The need for more energy-related renovation

To achieve targets set by the EU for the building sector, we need to get a clearer picture of what is needed for Europe’s non-residential stock. To allow designing suitable policies for the building sector, it is essential not just to know the current status of the building stock, but also entirely understand its metabolism and future characteristics. New construction, demolition and renovation activities are the most important factors in this context. In order to anticipate the future energy consumption and connected emissions in the building sector, it is not only vital to know the type of realised renovations, but also their quality.

In a recent study, Ecofys found that the overall renovation rate in the European Union’s non-residential building stock totals approximately 14% while only 3% thereof are energy-related renovations and a mere 0.3% represent ‘complete renovations’, where both, the interior building equipment (HVAC) as well as the building envelope (façade, roof, cellar ceiling) is retrofitted. However, it is energy-related renovations of that kind that Member States mainly need to address to get on track towards the aim of an “almost carbon-neutral building sector” in 2050.

Yet, as the study found, as few as one in one thousand buildings undergoes complete energy-related renovations in Hungary and Poland (0.1%) each year. InSweden, the annual figure is two in one thousand buildings (0.2%), while inGermanyit is four in one thousand (0.4%). Renovations inSpainwere also running at 0.4% in 2009. At those rates, less than one quarter of the non-residential building stock inGermanywill experience a renovation that will have a major effect on energy performance during a typical non-residential building’s lifetime of 55 years. InHungaryandPoland, the energy performance of just one in 20 buildings will be upgraded during the building stock’s lifetime.

The renovation demand should lead to a major increase in investments in energy efficiency measures and cleaner sources of energy for the buildings. But if renovation behaviours don’t change in the near future and the renovation rate cannot be increased significantly, the European Union will not achieve its greenhouse gas reduction targets in the building sector.
