Shed Roof the sunny side of the shed roof collects solar energy Architecture Shed Roof the sunny side of the shed roof collects solar energy the shaded side provides cool air for ventilation windows at shaded side provide even and natural illumination without direct sunlight

Selected Topics: Ventilation / Cooling Architecture Selected Topics: Ventilation / Cooling windows windows solar protection solar protection air air solar radiation solar radiation outside inside outside inside summer with sun protection winter

Architecture Typical Heat Bridges external wall cut trough concrete ceiling, cantilevered main bodies (balconies) attachments of all kinds non-insulated wall coping in roof slipped insulating layers, collapsed bulk insulations window reveals and window connections, window shutter boxes Installations, like pipe and wire ducts, integrated switchgear boxes etc.

Geothermal Heat Exchanger Architecture Geothermal Heat Exchanger Input Air Exhaust Air Heat Exchanger Geothermal Heat Exchanger Concrete tubes as heat exchanger Input air is cooled by heat exchange with the cooler soil

Activation of Construction Architecture Activation of Construction advantages to air conditioning: mild cooling no blowing higher economical efficiency Windows, breast and ceiling Glass façade, ceiling, part of floor cooling tube bundles combination of thermally active surfaces 1, from cold storage plant (day) 2, natural draft cooling tower (night)

Gross – Net Calorific Value Architecture Gross – Net Calorific Value Comparison of energy utilization Modern conventional boiler (natural gas) Condensing boiler (natural gas) Gross Net Gross Net condensation enthalpy heat losses in stack gas heat dissipation losses useable energy

Air conditioning - system Architecture Air conditioning - system Low pressure High pressure Heat source Heat utilization Boiler Condenser expansion valve

Zero-Emission-Factory Architecture Zero-Emission-Factory Walls and ceilings with timber-frame construction 70% energy being saved by high quality thermal insulation system and heat recovery of used air Solar collectors and Photovoltaics supply 30% of the needs for current and heating Using rapeseed oil for co-generation meets the remaining part of energy consumption 70% water consumption being saved in toilettes by vacuum drainage Passive cooling 50 % power being saved by optimized utilization of daylight and power saving office equipments 20% less revolving stocks by a consumption oriented logistics strategy Fa. Solvis GmbH
