In Algeria, the residential and tertiary sectors are the ones with the highest energy consumption making use of 34% of the total energy. The government has launched a thermal renovation program for existing buildings to reduce the energy consumption. The existing stock has 1.050.000 of masonry dwelling built before 1945. Masonry buildings represent a cultural heritage. Thermal renovation of masonry buildings in Algeria requires a comprehensive approach as it simultaneously involves a multitude of decision makers that can express a multitude of criteria. This paper presents an integrated method that combines the structured group interaction method Delphi, the Fuzzy Analytical Hierarchy Process (FHAP), and the Preference Ranking Organization Methods for Enrichment Evaluation (PROMETHEE) for the thermal renovation of masonry buildings with a heritage value. The aim of the proposed method is to rank the thermal renovation solutions using a fuzzy multi-criteria and multi-decision makers approach. A case study using the proposed method to obtain a full ranking of thermal renovation options is detailed in the paper.
