Bilma was the designer of the energy requalification of the property, a five floors residential building dating back to around 1930. After the first technical assessment a series of critical issues emerged including: the need to remove the thermal power plant no longer adequate; improve the energy performance of the building; centralize the production of heat and domestic hot water; the presence of 8 uprights for heat distribution up to the apartment radiators made it difficult to vary the layout of the floors; carry out some environmental remediation, finally the recovery of the attic to create two new real estate units.
Bilma, after having verified the state of the places, prepared a project which included, among other things: the connection to the district heating network as the only source of heat for the condominium; the creation of a small well-insulated vertical shaft to slide the uprights for heat distribution, for domestic hot water, the installation of meters at the entrance of each apartment; thanks to district heating which is considered a renewable source, the use of solar panels has been avoided; at the same time as the elimination of the flame-fired thermal power plant no more required the fire prevention certificate.
