1 SOLAR DECATHLON EUROPE 2010 PROTOTYPE SOLAR HOUSE UPC LOW ³ LOW ENERGY - LOW IMPACT - LOW COST LOW3 INTERMEDIATE SPACES IN ENERGY SELF-SUFFICIENT SOLAR HOUSES Torsten Masseck CISOL Solar Research Centre ETSAV Director LOW3_ Solar Decathlon UPC 2010 UPC_Barcelona Tech

2 Intermediate spaces Transitional spaces between interior and exterior Bioclimatic element Glass as building material Low energy architecture

3 LOW3 Concept Low energy _Low impact_low cost Bioclimatic house in house concept Industrialized, low cost building materials Passive low energy architecture

4 Micro climatic building skin Of the shelf agricultural greenhouse Adaptation to housing Integration of Solar Technologies Bioclimatic optimization

5 LOW3 Concept Modular, minimum floor plan Exploration of the potential of intermediate spaces Flexible, growing housing concept

6 South Façade Summer: Shaded intermediate space (ts= 7%) Winter: Collector Façade (U=2,4 W/m2K, g= 0,77) Integrated hot water solar collector (7,2 m2, solar fraction 87,3%)

7 Ventilated PV-roof 19º inclination (95% of maximum energy generation) 20 cm ventilated air gap for back ventilation Poly cristalline PV installation 4,0 kwp 6000 kwh/y (Madrid)

8 Bioclimatic Elements Shading Devices (fixed and flexible sun screens, south overhang) Cross ventilation (south façade and roof opening) Evaporative Cooling System (Active pulverisation) Sunspace /greenhouse effect (direct solar radiation and buffer space)

19 Energy efficiency analysis in the hot/cold radiant ceiling system, experimented in the LOW3 prototype Authors: Ludovica Rossi (LOW3 architecture designer - PhD students UPC) José Maria Nacenta Anmella (Departament de Màquines i Motors Tèrmics - Laboratori de Termotècnia - E.T.S. Enginyeria Industrial de Barcelona UPC Vicenç Rodríguez Barraguer (Departament de Màquines i Motors Tèrmics - Laboratori de Termotècnia - E.T.S. Enginyeria Industrial de Barcelona UPC - engineering researcher) Torsten Masseck (LOW3 Faculty Advisor of UPC - architect)

20 LOW3 Concept Box in a box concept Highly insulated living modules Actively conditioned floor area: 42 m2 Micro climatic building shell

21 Heating and Cooling System Air-water heat pump 2kW Radiant ceiling + batteries NAC Comfort Energy storage tank 750 l Enthalpic Air Heat Exchanger

22 Radiant ceiling system Radiant ceiling panels REHAUTHERM Approximately 30 W/m2 cooling power Cold/hot water battery with grill for condensation Air inlet through battery

23 NAC Comfort under load Temperature levels in different parts of the system Distributed radiant cooling effect Natural air circulation (down draft) under battery Intermediate response time

24 Subjective Perception Re-radiation of surfaces Lower surface temperatures Higher comfort with less cooling 26º C interior air temperature acceptable

25 Subjective Perception Re-radiation of surfaces Lower surface temperatures Higher comfort with less cooling 26º C interior air temperature acceptable

26 Conclusion Experimental stage of a low3 heating and cooling system Winter performance Overall energy consumption under real conditions to be evaluated
