The inner end of the hollow box is formed by an OSB board (Norbord), which also has the function of an airtight layer and a vapour control layer. The OSB board is screwed onto wooden T-beams (Steico company) and all butt joints are glued with airtight strips. With a board thickness of 15 mm, the OSB board achieves an Sd value of 3,0 – 4,5 m.

The client has decided to extensively renovate the building and to raise it to the most modern construction standard.\nThe aim of the renovation was to preserve the old building structure and achieve the living comfort of a passive house. To create sufficient room height, the building was undermined and placed on a reinforced concrete foundation.

A saw-rough silver fir formwork was applied to the OSB board. The combination of capillary-active properties of cellulose and the reduction of vapour diffusion through the OSB board contribute to the functionality of this solution.", "Why Does it work?": "The combination of capillary-active properties of cellulose and the reduction of vapour diffusion through the OSB board contribute to the functionality of this solution. Another essential aspect is the existing wood block wall. Due to the relatively high thermal resistance of the wooden wall, the temperature between the existing wall and the insulation is much higher compared to a solid stock wall. Another important factor is the air circulation through the wooden beams. The air exchange has a positive effect on the drying behaviour of the construction. Despite the lack of driving rain protection on the surface of the wooden wall, a certain constructive driving rain protection is given by the surrounding balcony and a relatively high base wall, which minimizes the moisture input from outside.

The client has decided to extensively renovate the building and to raise it to the most modern construction standard.\nThe aim of the renovation was to preserve the old building structure and achieve the living comfort of a passive house. To create sufficient room height, the building was undermined and placed on a reinforced concrete foundation.

The building is very characteristic for the village. Built in 1819 it is one of the oldest buildings of the village. It was built as former chandlers’ house with a connected barn and stable. Before the renovation, the house has been uninhabited for 40 years. The heritage preservation office has formulated clear requirements for the building, which is under monument protection, which were taken into account during the retrofit. Requirements for windows preservation: “Preservation of the historic window construction (an upgrade of the energy performance is possible): wooden windows with sash glazing bars and slender window frame, drip sill (Wetterschenkel) on the bottom side of the wooden frame.

To reduce transmission heat losses, the single glazing of the inner window sashes was substituted by a double-glazing. So that the historical narrow frame can hold the thicker glazing pane, it was reinforced on the outside by a wooden lath (see technical drawings). The insulating glazing was fixed again on the outside with putty (of linseed oil). The window frames were restored on-site by renewing the paint with linseed oil. The outer window sashes are painted with linseed oil paint in ochre according to the specifications of the monument office, while the inner window sashes are not painted with linseed oil paint as there is a risk that the linseed oil could damage the butyl of the insulating glass. Damaged outer panes were repaired with intact historical inner panes. Thus, all exterior windows have exclusively historical glazing. Airtightness of the windows was improved by adding a seal on the frame of the inner window. ", "Why Does it work?": "From the conservation point of view, the retrofit solution corresponds to the requirements of the heritage authority preserving the historic window construction and respecting all other criteria in terms of color and proportions. Minor visual changes were foreseen only on the inner view on the window: the replacement of the historic single glazing in the inner window sashes into the heavier double-glazing required the enlarging of the inner window frames with a wooden lath and also the float double-glazing has another appearance and optic with respect to the historic glazing. The integrated seal on the inner side of the window frame is only visible when the inner window sashes are open. Thus, the window appearance and proportions did not change at all from the outside and only slightly on the inside. \n\nAs regards the moisture safety the window construction after retrofit is generally moisture safe. Through the double-glazing in the inner window sashes, higher surface temperatures on the pane are obtained and thus less condensation risk. Surface temperatures in the angle between window frame and reveal are already higher in case of a box-type window. In case of the Knablhof interior insulation in the window reveal, avoids additionally condensation all around the window frame. The window manufacturer used special seals and a special manufacturing of the grooves which make it possible to make even slightly warped window frames completely airtight. Thus, no vapor can penetrate into the intermediate space between the two-window layer and condensate on the inner surface of the outer glazing. \n\nFinally from the energy point of view ventilation heat losses through leaky windows were decreased by improving the airtightness.

The building is very characteristic for the village. Built in 1819 it is one of the oldest buildings of the village. It was built as former chandlers’ house with a connected barn and stable. Before the renovation, the house has been uninhabited for 40 years. The heritage preservation office has formulated clear requirements for the building, which is under monument protection, which were taken into account during the retrofit. Requirements for windows preservation: “Preservation of the historic window construction (an upgrade of the energy performance is possible): wooden windows with sash glazing bars and slender window frame, drip sill (Wetterschenkel) on the bottom side of the wooden frame. Window colors in ochre with linseed oil paint, preservation of room layout, preservation of size and frame proportions, replacement of one window with a French door is possible”", "building_type": "Residential (rural)", "building_year": "1700-1800", "listed_building": "Yes", "conservation_area": "No", "building_structure": "Stone masonry wall", "country": "Italy", "city": "Racines (Mareit)", "latitude": 46.8922, "longitude": 11.3503, "altitude": 1040, "climatic_zone": "Dfc", "solution_year": 2017, "component_installation_year": "1900-1944", "what_is_the_solution": "The historic window construction consisted of box-type windows from 1930/34. To reduce transmission heat losses, the single glazing of the inner window sashes was substituted by a double-glazing. So that the historical narrow frame can hold the thicker glazing pane, it was reinforced on the outside by a wooden lath (see technical drawings). The insulating glazing was fixed again on the outside with putty (of linseed oil). The window frames were restored on-site by renewing the paint with linseed oil. The outer window sashes are painted with linseed oil paint in ochre according to the specifications of the monument office, while the inner window sashes are not painted with linseed oil paint as there is a risk that the linseed oil could damage the butyl of the insulating glass. Damaged outer panes were repaired with intact historical inner panes. Thus, all exterior windows have exclusively historical glazing. Airtightness of the windows was improved by adding a seal on the frame of the inner window. ", "why_does_it_work": "From the conservation point of view, the retrofit solution corresponds to the requirements of the heritage authority preserving the historic window construction and respecting all other criteria in terms of color and proportions. Minor visual changes were foreseen only on the inner view on the window: the replacement of the historic single glazing in the inner window sashes into the heavier double-glazing required the enlarging of the inner window frames with a wooden lath and also the float double-glazing has another appearance and optic with respect to the historic glazing. The integrated seal on the inner side of the window frame is only visible when the inner window sashes are open. Thus, the window appearance and proportions did not change at all from the outside and only slightly on the inside. \n\nAs regards the moisture safety the window construction after retrofit is generally moisture safe. Through the double-glazing in the inner window sashes, higher surface temperatures on the pane are obtained and thus less condensation risk. Surface temperatures in the angle between window frame and reveal are already higher in case of a box-type window. In case of the Knablhof interior insulation in the window reveal, avoids additionally condensation all around the window frame. The window manufacturer used special seals and a special manufacturing of the grooves which make it possible to make even slightly warped window frames completely airtight. Thus, no vapor can penetrate into the intermediate space between the two-window layer and condensate on the inner surface of the outer glazing. \n\nFinally from the energy point of view ventilation heat losses through leaky windows were decreased by improving the airtightness. Transmission heat losses were decreases by replacing the inner single glazing with a double-glazing (Ug = 1,10 W/(m²K) after; Ug = 5,75 W/(m²K) before).\n", "pros": "- The view from outside is completely preserved\n - Most of the parts of the original window construction can be preserved (all wooden parts).

Later on — with documented evidence as early as 1612 — the Community House was moved to Seyssel Square, but it wasn’t until 1789 that part of the current building was completed. Soon, however, the building appeared too small for the needs of the town, which had over 5,000 inhabitants, and in 1812, an expansion was begun based on a project by engineer Giovanni Casalis. We do not know when it was completed; however, by 1876, the municipal building already featured the 19th-century wing, and the 18th-century section had been significantly altered following the demolition of the internal stairs and the closure of the southern entrance.\nOver time, the building fell into a certain state of decay, leading the municipal administration to address the ongoing deterioration by initiating a conservation restoration in 2011. Thanks to the generous funding from the San Paolo Foundation, a bequest from a citizen of Sommariva, ………, and its own resources, the project was realized with substantial work on the council chamber, the Giunta hall (or \"Fathers of the Nation\" hall), the façade, and the furnishings, paintings, and prints.", "building_type": "Other", "building_year": "1600-1700", "listed_building": "Yes", "conservation_area": "Yes", "building_structure": "Brick masonry wall", "country": "Italy", "city": "Sommariva del Bosco (CN)", "latitude": 44.7697, "longitude": 7.7864, "altitude": 298, "climatic_zone": "Cfb", "solution_year": 2023, "component_installation_year": "1980-present", "what_is_the_solution": "The old window frames were made of lacquered wood, ivory-colored on the exterior and gray on the interior, with a traditional panelled design.

The only exceptions were some on the first floor, found in the council chamber and the Giunta hall, which were of an older origin but similar in shape and color to those of the other floors described above.", "why_does_it_work": "The window frames are made of laminated Scots Pine (Pinus Sylvestris) Finger Joint, consisting of a master frame and sash: a complete system for windows, constructed with wooden profiles with a moisture content of 10-12% and certified for sustainable forest management.

These profiles incorporate the energy and environmental characteristics required by European directives and national laws, while maintaining the narrow section width typical of the originals. The insulating glass, made with low-emissivity glass, is designed for Reinforced Thermal Insulation of glazed walls. It is ideal for insulating glass, enhancing thermal comfort and helping to reduce heating costs.\nThe product's energy characteristics (thermal transmittance, light transmission, and solar factor) are crucial and significantly impact the overall energy efficiency of the building.

Triple glazing: This provides superior thermal insulation compared to the original single-glazed windows with secondary glazing. 2. Inset installation: The new windows are recessed into the building's new internal insulation layer. This creates a continuous thermal and airtightness line, crucial for meeting the EnerPHit standard. 3. Omission of traditional elements: The new design removed the original sashes, transoms and mullions. While this was a departure from the building's heritage appearance, it was deemed necessary to maximise energy performance and daylighting. 4. Increased glazed area: The new windows increased the glazed area by 60% compared to the original windows, allowing for a 77% increase in natural daylight levels. 5. Improved thermal performance: Heat losses through the new windows are up to 35% lower compared to a double-glazed sash window with a traditional appearance. 6. Passivhaus certification: The windows meet the stringent Passivhaus standards, contributing significantly to the building's overall energy performance. 7. Bespoke manufacturing: Due to the specific requirements, the windows were sourced from an Austrian supplier, Inter norm, highlighting the current lack of suitable UK-based options for such high-performance windows. 8. Planning negotiation: The design team successfully argued for this modern window design within the conservation area, setting a precedent for balancing heritage considerations with urgent environmental sustainability needs.", "Why Does it work?": "1. Holistic approach: The window solution doesn't work in isolation, but as part of a comprehensive retrofit strategy. It integrates seamlessly with the new internal insulation and airtightness measures, creating a cohesive high-performance envelope. 2. Fabric-first principle: By focusing on improving the building fabric, including the windows, the solution addresses energy efficiency at its source, reducing the demand for heating and cooling. 3. Performance-driven design: The windows were specifically chosen to meet the rigorous EnerPHit standard, ensuring they contribute significantly to the overall energy performance goals. 4. Balanced compromise: The solution strikes a careful balance between heritage considerations and modern performance requirements. While some traditional features were omitted, the overall appearance remains sympathetic to the building's character. 5. Addresses multiple issues: The new windows solve several problems simultaneously - poor thermal performance, inadequate daylighting, and potential thermal discomfort - with a single intervention. 6. Future-oriented: By significantly exceeding current building regulations, the windows help future-proof the building against tightening energy standards. 7. Capitalises on technological advancements: The solution leverages modern glazing technology to achieve performance levels that simply weren't possible with traditional windows. 8. Tackles a major weakness: In many heritage buildings, windows are a significant source of heat loss. By addressing this weak point, the solution yields substantial energy savings. 9. Improves usability: The increased daylight and improved thermal comfort make the building more pleasant and functional for its users, supporting its continued use and relevance. 10. Sets new standards: By demonstrating what's possible in a conservation area, the solution works to shift perceptions and practices in heritage retrofits. 11. Addresses climate urgency: The high-performance windows contribute significantly to reducing the building's carbon footprint, aligning with urgent climate action needs.", "Pros": "1.

The building presents also a private courtyard and can use it as a common outside space. To benefit lights and outdoor spaces, oversized formers were created in the living rooms at the attic. This new building parts refer to the axes the arches of the courtyard and the existing Roof construction. On the neighbour area of the old artificial ice rink (KEB) on Calandastrasse in Chur, a new development with several apartment blocks has been implemented. A suitable replacement had to be created for the existing kindergarten by autumn 2015. The property at Calandastrasse 48/50, which is owned by the city of Chur, fulfils the requirements of the spatial program and is also suitable in terms of location and spatial qualities. Even if the building is not protected nor inserted in a conservation area, the owner (City of Chur) wanted to valorise the complex by making it a lighthouse for integration of energy saving and energy production in a refurbishment without demolishing the aspect. The heritage conservation was done from an urbanistic point of view more than form the choice of the construction details. In fact, the form, the shape and the walls of the building remains: the ensemble with the three-family house and especially the courtyard with the arch facade made of natural stone are the spatial parts worthy of preservation.

By moving on the opposite side, the roof space is optimally flooded with daylight. With a u-value of 0.41 W / m2K, the glasses on the north and east facade have a very good insulation value.

The building presents also a private courtyard and can use it as a common outside space. To benefit lights and outdoor spaces, oversized formers were created in the living rooms at the attic. This new building parts refer to the axes the arches of the courtyard and the existing Roof construction. On the neighbour area of the old artificial ice rink (KEB) on Calandastrasse in Chur, a new development with several apartment blocks has been implemented. A suitable replacement had to be created for the existing kindergarten by autumn 2015. The property at Calandastrasse 48/50, which is owned by the city of Chur, fulfils the requirements of the spatial program and is also suitable in terms of location and spatial qualities.

The heritage conservation was done from an urbanistic point of view more than form the choice of the construction details. In fact, the form, the shape and the walls of the building remains: the ensemble with the three-family house and especially the courtyard with the arch facade made of natural stone are the spatial parts worthy of preservation.

Nevertheless, it was crucial that the new roof should fit into the old village centre and not stand out surrounded by the traditional stone roofs.", "building_type": "Religious", "building_year": "1960-1969", "listed_building": "No", "conservation_area": "No", "building_structure": "information not available", "country": "Switzerland", "city": "3906 Saas-Fee VS", "latitude": "46.10722", "longitude": "7.92477", "altitude": 1792, "climatic_zone": "ET", "solution_year": 2022, "component_installation_year": "1960-1969", "what_is_the_solution": "Although the church council was convinced of the merits of solar energy, the snow load and the visual appearance of a solar church roof initially raised doubts among some parish representatives. The church council was unsure whether a modern solar church roof would suit a parish\nchurch. Although many solar roofs still consist of conventional solar panels, there are now solar panels that are adapted in terms of colour and structure and no longer even shine. In a construction with these panels, you cannot tell at first glance that it is a solar roof. The use of these modern solar panels then convinced the church council and the project was commissioned.", "why_does_it_work": "Over 700 individual modules of different sizes were produced for the church roof in Saas-Fee.

"Building Name": "Villa Castelli", "Description of the Building and of the Context": "Villa Castelli is a listed building from the 19th century located at the riverside of Lake Como (Italy). The owners set the ambitious goal of renovating the Villa, which had belonged to the family for about 140 years, to the lowest possible energy demand while maintaining the original use of the rooms and the external appearance. The renovation achieved a 90% energy demand reduction and a significant increase in comfort, demonstrating that also a listed building can become nZEB. The villa is under formal protection in two respects: the building is listed in the land-use plan as a building worth preserving (vincolo architettonico) and as part of the riverside landscape, it is situated in a protected area (vincolo paesaggistico). In general there was no detailed assessment prior to the retrofit planning and no description of possible retrofit interventions from heritage office side.

The installed ventilation system provides balanced air flow and achieves a maximum volume flow rate of 300m³/h – to reach the required air change volume of 0.4 m³/h and provide living areas up to 220 m² with fresh air, level 2 with 220 m³/h will be sufficient.", "why_does_it_work": "Heating\n\nAt Ansitz Kofler there was no space available in the house or basement for fuel storage, but the pellets could be stored in a tank buried in the garden and are brought to the reservoir in the heating room with a suction turbine. Burying the tank could be combined with the earth works anyway done for the tubes allowing to pre-heat the ventilation air in winter and pre-cool it in summer.\nIntegrating the distribution ducts in the floor allows to hide them, nevertheless this measure can be adopted only if modifications to the existing floors are not restricted. In the case of Ansitz Kofler the existing floor were tiles on some cm of screed on earth ground – dating anyway from 1925 and not from the Orangerie, it was not worthy of preservation.\n\nVentilation\n\nCompatibility with conservation: Integrating the distribution ducts in the floor allows to hide them, nevertheless this measure can be adopted only if modifications to the existing floors are not restricted.\nMoisture safety: With ventilation systems high indoor humidity which might induce condensation within the construction at any weak point is avoided.\nEnergy improvement: A central system for controlled ventilation with heat recovery ensures not only that the necessary exchange of air takes place automatically but also that the incoming air from outdoors is warmed by cooling the exhaust air (the “Air-to-Air Heat Exchanger” recovers up to 85 percent of the heat from outgoing air). Introducing an automatic summer bypass unit guarantees that the outside air almost completely bypasses the heat exchanger preventing the supply air from being additionally warmed during warm summer months.", "pros": "Heating\n\n- Renewable and CO2 neutral source for space heating and DHW (high efficiency and reliability while lowering solid and gaseous pollutant emissions).\n- No visual impact on the ensemble, since the pellets tank could be buried.\n- No material impact, as the pellets boiler itself was installed in the original heating room.\n\nVentilation\n\n- It provides better air quality, lower humidity and no condensation.\n- Keeping slight negative pressure avoids that warm, humid interior air enter via cracks into the construction (causing moisture issues there).\n- the constant supply of warm air through the heat recovery system can reduce energy costs because the environment temperature is kept constant, this provides greater comfort in cold climates. ", "cons": "Heating\n\n- Biomass heating technology could have potential disadvantages in terms of required space, emissions and maintenance, compared to conventional heating systems, such as oil or gas boilers.\n\nVentilation\n\n- Mechanical ventilation systems with heat recovery do require that filters and fans must be kept clean to ensure effective operation (additional maintenance costs). \n- The heat recovery work efficiently a good level of airtightness must be achieved in the rooms where it is installed, this can lead to additional costs.", "cost_quantitative_additional_information": "information not available", "lca_of_the_solution": "information not available", "pre_intervention_pictures": "No", "post_intervention_pictures": "Yes", "technical_drawings": "No", "additional_documentation": "Yes", "heat_generator": "Boiler (non condensing)", "fuel_type": "Gas", "centralized_decentralized": "Centralized", "distribution_system": "Water", "heating_supply": "Radiators", "heat_generator_2": "Boiler (condensing)", "fuel_type_2": "Biomass", "centralized_decentralized_2": "Centralized", "distribution_system_2": "Water", "heating_supply_2": "Radiating Floor", "nominal_power": "Not available", "efficiency": "information not available", "same_as_heating_system": "yes", "heat_generator_3": "information not available", "fuel_type_3": "information not available", "centralized_decentralized_3": "information not available", "same_as_heating_system_2": "yes", "heat_generator_4": "information not available", "fuel_type_4": "information not available", "centralized_decentralized_4": "information not available", "nominal_power_2": "information not available", "efficiency_2": "information not available", "cooling_unit": "No Cooling System", "centralized_decentralized_5": "information not available", "distribution_system_3": "information not available", "cooling_supply": "information not available", "nominal_power_3": "information not available", "efficiency_3": "information not available", "type": "Balanced Mechanical Ventilation", "centralized_decentralized_room_by_room": "Centralized", "heat_recovery": "Plate heat exchanger", "heat_recovery_efficiency": 0.85, "sfp_if_relevant": "information not available", "assessment_criterion_1ga_did_the_renovation_work_focus_on_improving_replacing_the_heating_system_or_adding_a_new_one": "Yes ", "assessment_criterion_1gb_did_the_renovation_work_focus_on_improving_replacing_the_cooling_system_or_adding_a_new_one": "No", "assessment_criterion_1gc_did_the_renovation_work_focus_on_improving_the_ventilation_strategy_or_adding_a_new_ventilation_system": "Yes ", "assessment_criterion_1h_what_is_the_heat_generator_after_the_retrofit_intervention": "Boiler", "assessment_criterion_2h_is_the_heating_system_centralized_or_decentralized_after_the_retrofit_intervention": "Centralized (multi family house/non residential)", "assessment_criterion_3h_what_are_the_heating_supply_units_after_the_retrofit_intervention": "Radiating Floor", "assessment_criterion_4h_was_the_existing_distribution_system_reused": "No", "assessment_criterion_5h_was_any_circular_strategy_applied_in_the_realization_of_the_new_heating_system": "No", "assessment_criterion_6h_how_would_you_rate_the_investment_cost_for_the_implementation_of_the_heating_system": "High", "assessment_criterion_1c_what_is_the_cooling_generator_after_the_retrofit_intervention": "No Cooling System", "assessment_criterion_2c_is_the_cooling_system_centralized_or_decentralized_after_the_retrofit_intervention": null, "assessment_criterion_3c_what_are_the_cooling_supply_units_after_the_retrofit_intervention": null, "assessment_criterion_4c_was_any_circular_strategy_applied_in_the_realization_of_the_new_cooling_system": "No", "assessment_criterion_5c_how_would_you_rate_the_investment_cost_for_the_implementation_of_the_cooling_system": "Medium High", "assessment_criterion_1v_what_type_of_automatic_ventilation_strategy_was_implemented": "Mechanical Ventilation System", "assessment_criterion_2v_is_the_ventilation_system_centralized_or_decentralized": "Centralized (multi family house/non residential)", "assessment_criterion_3v_is_the_ventilation_system_equipped_with_heat_recovery": "Yes", "assessment_criterion_4v_was_any_circular_strategy_applied_in_the_implementation_of_the_new_ventilation_strategy": "No", "assessment_criterion_5v_how_would_you_rate_the_investment_cost_for_the_implementation_of_the_ventilation_strategy": "High" }, { "id": "hcv_hcv0007", "sheet": "HCV_Sol.", "component": "HCV", "row": 12, "title": "Content -

The general situation of degradation and the need to minimize energy demand collide with the important aspect of historic buildings preservation. As usual at road forks and corner houses in the Kirchenfeld district, according to the Kirchenfeld-Brunnadern building inventory, the house was designed with special care: the south-east corner of the house is characterized by a corner risalite, which is covered with the mansard roof. The house is listed in the cantonal building inventory and classified as worthy of protection (highest protection level). For this reason, any changes must obtain the approval of the Department of Historic Monuments.", "Building Type": "Residential (urban)", "Building Year": "1850-1899", "Listed Building": "Yes", "Conservation Area": "Yes", "Building Structure": "Stone masonry wall" }, "Location info": { "Country": "Switzerland", "City": "Bern", "Latitude": "46.941479", "Longitude": "7.4528", "Altitude": 542, "Climatic Zone": "Cfb" }, "Solution info (Common Fields)": { "Solution Year": 2015, "Component Installation Year": "1850-1899", "What is the solution?": "The new heating system includes several interventions: \n- The main source is the water heat pump, which is supplied partly by geothermal probes and partly by the PVT system. The water is stored in a 2840 litters tank.\n- It also works thanks to the stove. The stove can be easily integrated into new or existing heating and hot water systems.\n- Combined with a thermal solar system, the entire heating system can be designed. \nThis not only reduces heating costs, but also the environmental impact, because is CO2 neutrally. \nIn addition, a 'Frischwasserstation' which contains a small heat exchanger to provide our warm water (Brauchwasser) on demand which prevents the formation of legionella were installed. The hot water of the solar tank is used to heat up the 'Brauchwasser' in the Frischwasserstation when required. From the tank the water is then distributed to the historical radiators and wall radiators. Since originally no conventional solar system was possible due to monument preservation regulations, a thermal collector that is not visible from the outside has been developed, with which the heat can be efficiently extracted from the natural slate roofing. The collector consists of copper lamellas, which are clamped between the slate plates. The heat is conducted via the fins into a soldered copper tube, through which it is dissipated via a glycol solution, as in conventional collectors. Due to possible condensation moisture and to increase efficiency, a 1cm aerogel insulation, covered by a sub-roof foil, was placed between the roof battens and the slate. The total thermal generation is around 10,000 kWh of heat per year.", "Why Does it work?": "A combination of several energy renewable sources has been implemented to achieve the best energy efficiency balance for the building considering the high level of protection. The goals for the renovation of this building are manifold: minimize energy demand (reach a Minergie level, the Swiss standard of quality, comfort and energy efficiency), use environmentally friendly building materials, maintaining the character of the house (preservation of historical monuments), consider urban environment, adhere to the cost framework (subsidies as Minergie and Bern renovated) and, where necessary, seek and implement new solutions. The challenge is to achieve maximum results while preserving the original historical value of the building (minimum impact). The whole system has been designed to perfectly integrate with the construction. The heat is distributed through radiators and through a stove. Historical radiators were not changed during the renovation (except newly painted) and wall radiators have been fitted to the wall with a minimal intervention in terms of space. The water heat pump is supplied partly by geothermal probes and partly by the PVT and the natural slate collector systems.

As usual at road forks and corner houses in the Kirchenfeld district, according to the Kirchenfeld-Brunnadern building inventory, the house was designed with special care: the south-east corner of the house is characterized by a corner risalite, which is covered with the mansard roof. The house is listed in the cantonal building inventory and classified as worthy of protection (highest protection level).

The water is stored in a 2840 litters tank.\n- It also works thanks to the stove. The stove can be easily integrated into new or existing heating and hot water systems.\n- Combined with a thermal solar system, the entire heating system can be designed. \nThis not only reduces heating costs, but also the environmental impact, because is CO2 neutrally. \nIn addition, a 'Frischwasserstation' which contains a small heat exchanger to provide our warm water (Brauchwasser) on demand which prevents the formation of legionella were installed. The hot water of the solar tank is used to heat up the 'Brauchwasser' in the Frischwasserstation when required. From the tank the water is then distributed to the historical radiators and wall radiators. Since originally no conventional solar system was possible due to monument preservation regulations, a thermal collector that is not visible from the outside has been developed, with which the heat can be efficiently extracted from the natural slate roofing. The collector consists of copper lamellas, which are clamped between the slate plates. The heat is conducted via the fins into a soldered copper tube, through which it is dissipated via a glycol solution, as in conventional collectors. Due to possible condensation moisture and to increase efficiency, a 1cm aerogel insulation, covered by a sub-roof foil, was placed between the roof battens and the slate. The total thermal generation is around 10,000 kWh of heat per year.", "why_does_it_work": "A combination of several energy renewable sources has been implemented to achieve the best energy efficiency balance for the building considering the high level of protection. The goals for the renovation of this building are manifold: minimize energy demand (reach a Minergie level, the Swiss standard of quality, comfort and energy efficiency), use environmentally friendly building materials, maintaining the character of the house (preservation of historical monuments), consider urban environment, adhere to the cost framework (subsidies as Minergie and Bern renovated) and, where necessary, seek and implement new solutions. The challenge is to achieve maximum results while preserving the original historical value of the building (minimum impact). The whole system has been designed to perfectly integrate with the construction. The heat is distributed through radiators and through a stove. Historical radiators were not changed during the renovation (except newly painted) and wall radiators have been fitted to the wall with a minimal intervention in terms of space.

The chimney effect in combination with leaky windows provided certain effect of natural ventilation. However this sort of natural ventilation was unregulated and created additional heat losses during the heating season. After the renovation, the house was equipped with a mechanical ventilation system with cascaded air distribution. This means that fresh air is directed into the bedrooms and living rooms. The exhaust air is extracted from the bathroom, WC and kitchen. One heat recovery unit for each dwelling unit with a nominal air flow rate of 150-250 m3/h each were used.", "Why Does it work?": "There were no monument protection or historical prescriptions available. However, the builder wanted the ventilation ducts and elements to be as invisible as possible so the air ducts were mounted within the ceilings, in order to avoid any visual impact of the historic interiors. The design of the supply air outlet was adapted to the historic wooden ceiling. An additional way to minimize the air ducts was the use of cascade ventilation. The air passes over from bedrooms and living rooms via the corridors to the bathrooms and kitchen. When the heating system was changed to floor heating, the originally negative pressure driven ventilation through leakages is substituted by mechanical ventilation to ensure the dehumidification and good air quality. The high heat recovery rate guarantees draft free supply air and the counterflow heat exchanger ensures high energy efficiency for heat recovery.", "Pros": "- The ductwork does not influence the visual aspect of the interiors.\n- Individual unit for each dwelling has the advantage to get rid of any additional effort for fire protection.\n- The highly efficient heat recovery assures high comfort and reduction of ventilation losses.", "Cons": "- The use of one heat recovery unit per dwelling has the disadvantage of more duct work and more costs compared to a central system.", "Cost (quantitative) -

The chimney effect in combination with leaky windows provided certain effect of natural ventilation. However this sort of natural ventilation was unregulated and created additional heat losses during the heating season. After the renovation, the house was equipped with a mechanical ventilation system with cascaded air distribution. This means that fresh air is directed into the bedrooms and living rooms. The exhaust air is extracted from the bathroom, WC and kitchen. One heat recovery unit for each dwelling unit with a nominal air flow rate of 150-250 m3/h each were used.", "why_does_it_work": "There were no monument protection or historical prescriptions available. However, the builder wanted the ventilation ducts and elements to be as invisible as possible so the air ducts were mounted within the ceilings, in order to avoid any visual impact of the historic interiors. The design of the supply air outlet was adapted to the historic wooden ceiling. An additional way to minimize the air ducts was the use of cascade ventilation. The air passes over from bedrooms and living rooms via the corridors to the bathrooms and kitchen. When the heating system was changed to floor heating, the originally negative pressure driven ventilation through leakages is substituted by mechanical ventilation to ensure the dehumidification and good air quality. The high heat recovery rate guarantees draft free supply air and the counterflow heat exchanger ensures high energy efficiency for heat recovery.", "pros": "- The ductwork does not influence the visual aspect of the interiors.\n- Individual unit for each dwelling has the advantage to get rid of any additional effort for fire protection.\n- The highly efficient heat recovery assures high comfort and reduction of ventilation losses.", "cons": "- The use of one heat recovery unit per dwelling has the disadvantage of more duct work and more costs compared to a central system.", "cost_quantitative_additional_information": "information not available", "lca_of_the_solution": "information not available", "pre_intervention_pictures": "No", "post_intervention_pictures": "Yes", "technical_drawings": "No", "additional_documentation": "No", "heat_generator": "Boiler (non condensing)", "fuel_type": "Oil", "centralized_decentralized": "Centralized", "distribution_system": "Water", "heating_supply": "Radiators", "heat_generator_2": "Heat Pump ", "fuel_type_2": "Electricity", "centralized_decentralized_2": "Centralized", "distribution_system_2": "Water", "heating_supply_2": "Radiating Floor", "nominal_power": 12.3, "efficiency": "information not available", "same_as_heating_system": "no", "heat_generator_3": "Direct Electric", "fuel_type_3": "Electricity", "centralized_decentralized_3": "Decentralized", "same_as_heating_system_2": "yes", "heat_generator_4": "information not available", "fuel_type_4": "information not available", "centralized_decentralized_4": "information not available", "nominal_power_2": "information not available", "efficiency_2": "information not available", "cooling_unit": "No Cooling System", "centralized_decentralized_5": "information not available", "distribution_system_3": "information not available", "cooling_supply": "information not available", "nominal_power_3": "information not available", "efficiency_3": "information not available", "type": "Balanced Mechanical Ventilation", "centralized_decentralized_room_by_room": "Decentralized", "heat_recovery": "Plate heat exchanger", "heat_recovery_efficiency": "information not available", "sfp_if_relevant": "information not available", "assessment_criterion_1ga_did_the_renovation_work_focus_on_improving_replacing_the_heating_system_or_adding_a_new_one": "Yes ", "assessment_criterion_1gb_did_the_renovation_work_focus_on_improving_replacing_the_cooling_system_or_adding_a_new_one": "No", "assessment_criterion_1gc_did_the_renovation_work_focus_on_improving_the_ventilation_strategy_or_adding_a_new_ventilation_system": "Yes ", "assessment_criterion_1h_what_is_the_heat_generator_after_the_retrofit_intervention": "Heat Pump", "assessment_criterion_2h_is_the_heating_system_centralized_or_decentralized_after_the_retrofit_intervention": "Decentralized (multi family house/non residential)", "assessment_criterion_3h_what_are_the_heating_supply_units_after_the_retrofit_intervention": "Air outlets", "assessment_criterion_4h_was_the_existing_distribution_system_reused": "No", "assessment_criterion_5h_was_any_circular_strategy_applied_in_the_realization_of_the_new_heating_system": "No", "assessment_criterion_6h_how_would_you_rate_the_investment_cost_for_the_implementation_of_the_heating_system": "Medium Low", "assessment_criterion_1c_what_is_the_cooling_generator_after_the_retrofit_intervention": "No Cooling System", "assessment_criterion_2c_is_the_cooling_system_centralized_or_decentralized_after_the_retrofit_intervention": null, "assessment_criterion_3c_what_are_the_cooling_supply_units_after_the_retrofit_intervention": null, "assessment_criterion_4c_was_any_circular_strategy_applied_in_the_realization_of_the_new_cooling_system": "No", "assessment_criterion_5c_how_would_you_rate_the_investment_cost_for_the_implementation_of_the_cooling_system": "Medium High", "assessment_criterion_1v_what_type_of_automatic_ventilation_strategy_was_implemented": "Mechanical Ventilation System", "assessment_criterion_2v_is_the_ventilation_system_centralized_or_decentralized": "Decentralized (multi family house/non residential)", "assessment_criterion_3v_is_the_ventilation_system_equipped_with_heat_recovery": "Yes", "assessment_criterion_4v_was_any_circular_strategy_applied_in_the_implementation_of_the_new_ventilation_strategy": "No", "assessment_criterion_5v_how_would_you_rate_the_investment_cost_for_the_implementation_of_the_ventilation_strategy": "Medium Low" }, { "id": "hcv_hcv0018", "sheet": "HCV_Sol.", "component": "HCV", "row": 23, "title": "Content -

The building is particularly characterized by its impressive ornamental half-timbered construction on the east side and the slate panelling on the west side.

Together with the market place buildings, the town hall is under ensemble protection.

In the shop, the 36W fan built into the wall allows excess heat to be removed from the salesroom in the morning hours during the summer and cool air to be drawn in via a supply air opening on the north-west side. At the beginning of the renovation measures, the Ritterhof had no connection to the sewage system. Today, the domestic hot water is mainly heated by the pellet boiler, with a solar system supporting the heating and covering most of it in summer.", "why_does_it_work": "The intervention improves indoor comfort and does not affect the preservation of the original architectural features as it simply replaces the previous system. The new heating system uses a more economical and sustainable source than the previous system, which also guarantees a higher level of energy efficiency.

In their place a new ceiling heating system (2,063 m²) has been installed. \nFor the cooling system, 2 heat pumps have been installed along with a thermodynamic system (type Outdoor air - underfloor water) with an EER: 2.74 and a nominal and unit power of 144 kW. As emitters cold air supply (396 m²), radiant ceiling (1,590 m²) and air handling unit ventilation network (245 m²) have been chosen.\n\nVentilation\nThe solution consist of the installation of dual-flow ventilation in place of natural ventilation by opening windows with a 77% heat exchanger efficiency. Single flow ventilation have been chosen in bathrooms.\nThe solution was studied to not impact on the facade.", "why_does_it_work": "The renovation work involved improving the thermal quality of the building envelope by providing new insulation for the walls, roofs and lower floors.

Braces or ‘dwangs’ were fastened at right angles to the joists where additional lateral stiffness was necessary. To improve the airflow in the solum, it had to be cleared of about 40 rubble bags of debris. Following the repair and upgrade of the timber joists on the ground floor, wood-fibre insulation was fitted between the joists. The wood-fibre insulation is a semi-rigid batt, 100mm thick.
