Bilma was responsible for designing the energy requalification of a five-story residential building constructed around 1930. After the initial technical assessment, several critical issues emerged. These included the need to replace the outdated thermal power plant, improve the building’s energy performance, and centralize the production of heat and domestic hot water. Additionally, the presence of eight vertical uprights for heat distribution made it difficult to modify the floor layouts. Environmental remediation was also required, along with the conversion of the attic into two new real estate units.
After assessing the condition of the property, Bilma developed a project that included, among other things, the connection to the district heating network as the sole heat source for the condominium, the creation of a small, well-insulated vertical shaft to house the uprights for heat distribution, and the installation of meters at the entrance of each apartment. Due to the use of district heating, which is considered a renewable source, the installation of solar panels was avoided. Additionally, the removal of the outdated flame-fired thermal power plant eliminated the need for a fire prevention certificate.
