HPR San Lorenzo

The project for the Energy Renovation of a 30-year-old apartment building is based on a thorough Analysis of the Current State of the premises, a Solar Radiation Study, and the Calculation and Analysis of the Thermal Behavior of the Current Cladding, Glazing and Roofing. As a result, the project proposes a series of improvements for the building’s exteriors, adding renewable-energy sources as well as the repurposing of the roof for both a communal recreational area and an annex of two apartments.

​

The design of the former, in the front, incorporates the photovoltaic panels and terraced plots for urban agriculture to the recreational area. A sunshade shelters the seating area, equipped with barbecue grills and green areas.

​

The two-apartment annex is bioclimatic and highly-efficient, as they use a third of the energy consumed by a traditionally-designed apartment. Not only do they source their hot water through solar panels, but also the cladding has no thermal bridges and its thermal transmittance reaches a level B in the IRAM Guidelines.
