Energy retrofitting of historic or existing buildings is a challenge that it has not yet been properly solved. Multiple projects and methodologies are published every day but neither of them with the holistic approach that will assure success since the design phase. Nevertheless, these buildings play a key role in the achievement of the ambitious energy saving and greenhouse gas reduction targets that Europe has fixed for 2020 and 2050. Research has demonstrated that the impact in terms of decrease of energy use and CO2 will be strong, considering that, in Europe, 80% of the 2030 building stock already exists and 30% are historical buildings. To achieve these goals, reliable data about energy consumption, building components and systems performance of the existing building stock is needed. With the residential stock occupying a 75% of Europe’s floor space, this becomes a difficult task as this stock is never considered as a whole. Its components are installed, serviced and maintained by different companies and in different stages without a holistic approach to the overall building operation. The result is a lack of energy efficiency and feedback of the solutions implemented once the buildings are refurbished. This paper presents a pre-assessment methodology to tackle the energy retrofitting of historic and existing residential buildings based in the Maturity Matrix Assessment. The maturity of the implementation of energy efficiency measures in Brussels historic residential stock is evaluated to measure the gap between the “as is” and “to be” and define future appropriate strategies. The matrix synthetizes appropriate strategies for this specific stock that provides a global map of the problematic, requirements and solutions.
