General description
The project foresees the demolition of an old building with a high level of energy consumption and the realization of a new Passive House building: a dry technology multi-residence, made with structural wood panels. This technology reach less walls thicknesses as well as important energetic performances and a construction time reduction of 60% compared to traditional wet technologies. In this case, the dry technology chosen was forced by project needs and scopes, over all considering some normative prescriptions as shape’s respect and boundaries limitations: each increase of walls dimensions would have produced a decrease of useful surfaces. In addition to that, timing reductions produce important benefits, overall in economic terms: less bank’s debt and a faster income for clients. The functional building envelope has, at last, a thickness of 40 cm and its stratigraphy could develop important energetic performances, both in term of transmittance (U=0.136 W/m2k) and of thermal lag (λ=16 hours). These performances in a traditional building (made with concrete and slabs) require thicknesses exceeded 30%. In continuity with energetic performances, the project devise the use of triple-glazed windows (UG=0,6W/m2k) as well as the integral and continuing insulation into all building overhangs, in proximity to junctions between opaque and transparent envelope, and in adherence with padding, sills and docks.

Energy efficiency and use of renewables
The project foresees a strong application of renewable energy sources (RES) to fulfill the energy demand. A PV plant will be installed on the roof supplying 10 kw of energy. An heat pump will be installed in order to provide hot water with the PV plant energy. The thermal energy needs is currently around 11 kwh/m2/year.
Gross building strucutre + technical service costs
1500 (EUR/m² of Treated Floor Area)
