Akerra buildings meet the regulatory criteria (e.g. PEB, RT 2020) but are designed to achieve enhanced energy performance objectives.
The project characteristics obviously depends on the environmental context. For example, in a dense urban area, the renewable energy potential of the site is often insufficient to reach the global zero energy objective and only the zero thermal energy objective will be retained.
The target energy performance level in the technical study will be evaluated using specific performance indicators. Evaluated on a full annual cycle, these metrics serve as a basis for equiment sizing. It should be noted that the real level of performance achieved depends on the climatic conditions as well as the consumption practices of the residents. The performance evaluation will therefore only be valid if carried out at the end of at least twelve months of occupation.
