The challenge was to create a simple,sustainable, two-storey unit that would fit into a special site: a matureforest inside a northern Romanian city.
House Che subtly rises aroundthe inner courtyard in a mesmerizing natural environment with whom the buildingcommunicates through wide openings and various inner-out passages.
The house was designed andbuilt to reach the passive house standard in the harsh climate conditions ofnorthern Romania (Suceava) and is in the passive evaluation process. Theestimated energy demanded for heating and hot water is lower than 14kwh/sqm/year (according to preliminary phpp calculations).
The natural day factor is fourtimes bigger than the usual amount while the generous glazed surfaces alsoincrease the solar passive energy gain. The iconic shape of the roof maximizesthe solar input used for heating, offering in the meanwhile a contemporarydynamic expression.
To match the surroundings,exterior finishing is made out of natural cedar slats that preserve theirphysical-chemical properties even in the northern climate. The green roofrecovers the vegetal surface displaced for the house construction.
The minimal need for heatingis covered by a ground/water power heat pump. Photovoltaic panels will beinstalled on the roof at a later stage in order to provide the electric energynecessary for vital consumption and domestic hot water is obtained throughsolar thermal collectors and a heat buffer tank.
