Offenbach, Germany (under construction) MIXED OFFICE+RESIDENTIAL UNITIS Arch: B&G 1970s Landmark Architecture 280 kwh/m²a Refurbishment (under construction) 56 kwh/m²a
RENOVATION CHALLENGES NO THERMAL INSULATION THERMAL BRIDGES THICK CONCRETE LAYER HIGH OPERATIONAL COSTS DESIGNATED HERITAGE BUILDING (FACADE PRESERVATION) HIGHLY CONDUCTIVE ALUMINIUM Thermal Conductivity Comparison insulation concrete Aluminum
OUR APPROACH INTERNAL THERMAL COMFORT INTERIOR INSULATION: ELIMINATE THERMAL BRIDGE PRESERVE FACADE ADD INSULATION ENSURE MINIMUM HEAT TRANSFER REDUCE HEATING DEMAND Energy Reductions Due to Facade Improvement Heating Energy Demand Old Facade New Facade, doublepane glazing New facade, triplepane glazing
HOW TO FUND A RENOVATION PROJECT COST-EFFECTIVENESS ANALYSIS: FUNDING OPTIONS IN GERMANY Maximum Funding 30 units x 75,000 Euro x 22.5% = 506,250 Euro This project will receive 0.5 million euros to achieve a more energy-efficient building after renovations
