3. •31/12/2020: New constructions to be certified as nearly zero-energy
buildings
•31/12/2018: Public buildings certified as nearly zero-energy buildings
•No specific target for renovation.
JUSTIFICATION
DS²BE Doctoral Seminar on Sustainability Research in the
Built Environment
30/04/2014
2010/31/EU Directive
• Residential buildings consume 2/3 of the final energetic consumption of
buildings representing a 70% of the built-up area
• Refurbished buildings are the leading cause of CO2 emissions
• Energetic efficiency achievement requires striving to improve the energy
management of the existing residential buildings
Gaterell & McEvoy
• Construction consumes a 40% of the energetic demand
• 20% reduction in the consumption of primary energy
• Construction as a key factor in the energy consumption reduction
European Commission
Horizon 2020
• New constructions built under passive standards
• Refurbishment of public building performed by means of low energy
consumption standards
• Promotion of model houses and sustainable neighbourhoods
• Definition and application of a system to analyse the energy efficiency of
social housing stock
• Improvement of the energetic subsidies in the regional plans

5. “It is possible to define a methodology to identify the most optimal refurbishment
solutions, with regards to the improvement of energy efficiency, to apply to any building
belonging to the stock of historical residential buildings located in the area named East
Extension of Brussels, based on a clear typological building classification and the
identification of the applicable solutions”

HYPOTHESIS
6. GENERAL OBJECTIVES
# Objective
1 Define a methodology to support during the energy efficiency refurbishment of
historical buildings constructed between 1870 and 1930 in the East Extension of
Brussels, based on the outcomes of the REH
2 This methodology will be generalizable to all the buildings belonging to the same
DS²BE Doctoral Seminar on Sustainability Research in the
Built Environment

typology.
3 The methodology must be extensible to be reused in any building typology
4 The methodology must include a continuous improvement process to adjust and to
adapt the methodology by using the results and the feedback obtained from the
experience.
