Implementation of the Swiss national building renovation program Das ebäudeprogramm for 6 States (Kantone) io. 0/a Activity leader IA VS Task erformance & Reliability of V Systems reliminary Remark: This is not a bouquet of astonishing IV buildings which are implemented with 0.5% V market share! This presentation is not a report of recent TNC project. Here are some considerations reflecting my 40 years of experience in solar power (V and thermal), housing technology and building efficiency. I will make here my own proposal for the possible steps of the V community and the industry to help improve energy and ecological wise the existing building stock in urope. From V Systems to nergy Solutions 7040008) «From V Systems to nergy Solutions» Agenda What makes hotovoltaic in buildings so important? Why do we need a joint uropean plan to allow high V penetration in the power grid? How do we emerge from lower cost V [ /kwh] market to a nergy Solution rovider? Why ower to heat, ower to storage and power to wheel? Seven Conclusions 0 500 000 500m
What makes hotovoltaic in buildings so important? Why should we start with the existing building stock? U uildings 5% of power, 6% CO emission! uildings allows longterm investments 5+ years. Credible owners have access to low interest capital. Domestic buildings pay high electricity rates. The thermal and electrical improvement of uropean domestic building-stock is 00bn long-lasting decentralized market. V modules are an important, but small part of the total investment. A important challenge: how can the owner (legally) share the cost with the renting party? How do we develop from cost driven V market [ /kwh] to a four dimensions nergy Solution rovider? lectrical & Thermal fficiency 08) lectro obility clever V Smart rid connection 0 500 000 500m lectrical fficiency in buildings Thermal fficiency in existing buildings CFL 00 LD 0 00 W CFL 8 W LD 0.5 W 879-990 < 50 kwhl/m RA < 5 l/m RA [fuel oil] RA = nergy Reference Area [m ]

Conclusions I Conclusions II onday We need V when retrofitting the U building stock. V offers attractive solutions and processes to improve energy solutions for buildings and allows almost CO free individual mobility. Tuesday Successful energy solutions have to address the thermal and the electrical efficiency. Thursday With market share of 5% 0% of V, the challenge is to provide smart grid connections of sustainable V houses. V self-consumption makes good technical and good economical sense. can nhance it by power to heat and power storage. Inverters are able to provide further grid services. Wednesday For clever V in buildings we aim to distribute V uniformly over 6 hours by orienting modules east and west with marginal losses in yield. Thanks to the economical progress and self consumption we can use V systems, which produce 00% and more of the annual electrical demand. Friday uy your electromobile today and charge it with V ower to wheel 0 000 km/a means additional 4-5 kwp of V with high self consumption. rid claimable services are in the same range as conventional buildings. Conclusions III Saturday The main challenge: we need a joint uropean plan to allow high V penetration in the power grid. The presented index may help develop such a common plan. Sunday hotovoltaic is part of the solution, and not a problem! To keep V attractive, we have to start developing todays V systems into integrated parts of the energy solution. Sustainable energy buildings with mobility can be a part of this solution. DF www.tnc.ch any thank`s to the TNC V Team Thomas Vontobel Ralph Lingel Stephanie Fehling Q & A TNC 00
