Green space urbanization

  1. 1. Key features :Surface : 300m² GFAConstruction method : wood frame on slab and basementEnergy need of heating : 8 Kwh./m²labels : PassivHaus (passive house) et Effinergie BBC(Low Energy Building)Summer comfort : Ground-coupled heat exchanger andnatural over-night ventilationHeating Solution :(under study) mass stove with adistribution via the mechanical ventilationHot water : SolarOther Features : green roof, rainwater harvesting,photovoltaic electricity production. Energy-plus-houseBudget : 1600 € HT /m²Workers: Denisse Caizatoa, Yolanda Tolosa, Paula Garcia,Nadia Mimbrera, Cristina Anaya and Natalia Perez.
  2. 2. Comments :This large bioclimatic house was desired by the client.This house shows that one can go very far on theecological plan without abandoning comfort andaesthetics. Its performances are that of a passive house.Even better the production of renewable energy makes thebuilding an energy-plus building.Its originality lies in its reversible mass stove which willassure not only the need for heating, but also tocontribute to the cooling of the house in summer by usingits important mass stove during this period. Athermodynamic simulation was conducted to calculate theimpact of different possible scenarios to refine theselection and identify areas of the house requiring aspecific hot or cold contribution depending on the time ofthe year.
  3. 3. Everything is designed and optimized up to the smallestdetail: the mix of the construction techniques is used as acombination of the used materials. The position of thedifferent elements has been designed to optimize theirperformance as well the comfort perceived by the user.The solar control is extremely pushed but appeals aboveall in simple solutions requiring little maintenance. Thenumerous glazed surfaces guided by the contemporaryarchitecture of this vast villa impose joiners workshopsand very successful glazings to respect the objectives.The insulation and the sealing against air have requiredstudies and a rigorous implementation. The green roofallows to compensate partially the carbon well thatconstituted the vegetation eliminated by the house butalso to contribute to the thermal regulation of the building;in particular in summer by absorbing the main part of thesolar attacks.
