Giordano-Lanzi House

It has been a basis design parameter to reduce as much as possible the use of active energy strategies like plants, artificial lights and mechanical ventilation.

Some energy simulations provide us the opportunity to reach the best synthesis between thermal comfort level and natural daylight, maximizing the use of passive strategies (cross ventilation, free cooling, sunlight thermal energy, ecc.). The air quality in all the room is controlled and optimized to keep temperature, relative humidity and CO2 level within set range.

The basic focus has been maximize passive energy strategies to optimize the building energy needs. Despite several restrictions due to strict civil building regulations the building has been designed to reduce north glass partition and maximize views on the south and west walls. Optimal insulations has been reached reducing thermal bridges, creating an air tight envelope that will be tested with blower door test and also designing a ventilated façade in the second level envelope. Thereby the need for energy to reach the optimal comfort has reached a level of 37 kWh/m2 and with the supplementary use of energy for hot water, ventilation, light, ecc. The overall energy use is around 47 kWh/m2.

Heat pumps with a COP of 4,64, mechanical ventilation with heat recovery, sunlight responsive raffstore in the windows and 43,68 kWh/m2 of PV supplied energy imply that the final need of grid energy use will be around 5kWh/m2.

The building has been designed to maximize the use of dry technologies to allow the most effective regenerative process of building materials at the end of their use. The bearing structure, on the other hand, and the envelope has been design with concrete and brick technologies mainly to reduce economical impacts of the construction and of course could be reused after the internal partition and false walls and ceiling disassembly.

The outer surface of the second level is designed with completely reusable aluminum cladding, as well as the windows frame. All the wood used in the construction, especially the structure of the roof, comes from forests that are FSC certified
