ENERGY EFFICIENCY IN HISTORIC BUILDINGS

Refurbishment of historic buildings is a unique condition in many European Countries. Due to the need of developing a harmonized approach focusing on historic buildings rehabilitation, in 2014 AiCARR published a specific Guidelines. On this base, a further effort has been made developing an updated and revised guide at European level on the behalf of REHVA and with the inclusion of case studies from several European countries. In this work, the methodology to carry out energy audit of historic buildings is described, as implemented in the Guidelines, which focus on the needs and peculiarities of the cultural heritage that designers have to face with. The proposed methodology also provides to the institutions, responsible for protecting the building, objective criteria in deciding what energy saving opportunity is complying or not with conservation purposes
