ES-SO White Paper EPBD on overheating risk in low energy buildings

22 November 2016

Buildings in Europe account for about 40 % of the total energy consumption and of 36% of the CO2 emissions. Currently, about 35% of the EU's buildings are over 50 years old. By improving the energy efficiency of buildings, Europe could reduce total EU energy consumption by 6% and lower CO2 emissions by about 5%. (Source: http://ec.europa.eu/energy/en/topics/energy-efficiency/buildings).


ES-SO is strongly supporting the Energy Performance of Buildings Directive (EPBD) which has since its Recast in 2010 given to Member States a powerful means to improve the energy performance of their buildings. The EU Commisison launched on 30th November 2016 its Clean Energy package.  

ES-SO would like to stress a point of attention, which is not sufficiently addressed:

"Overheating risk in low energy buildings to combat": Low energy construction methods and a progressing climate change are reported as playing a significant role in increasing overheating in new built and renovated buildings, which will shift the energy need for heating into more energy needed for cooling. To address this properly an explicit article on overheating has to be included in the coming EPBD review.

Joint Position Paper EPBD

14 November 2016

Revising the Energy Performance of Buildings Directive: Tapping the potential of windows, Joint Position Paper

For the first time, the building glass façade and window industry represented by European Aluminium, EuroWindoor, ES-SO and Glass for Europe come together to call for a modernised EPBD to unleash the energy savings potential of high performing windows.

Windows and glazed areas in buildings are essential to the overall energy performance of buildings but also to the general comfort and well-being of people living and working in these buildings. To reap these distinctive benefits of modern windows, the four associations call for a revision for the Energy Performance of Buildings Directive, in particular to ensure the energy performance of glazed areas is fairly assessed and to put in place the right mechanisms and incentives for market actors to deliver massive energy savings.


In the joint position paper enclosed, the signatories call on the European Commission to consider three priorities ahead of its review of the EPBD:
1. Increasing the renovation rate of European buildings to obtain larger energy use reductions
2. Using the energy balance approach to assess the energy performance of windows
3. Recognising the benefits of daylight, natural ventilation and solar management

ES-SO Position Paper 2015

15 April 2015

Solar and daylight management as an essential concept in energy performance buildings, ES-SO Position paper 2015

Solar and daylight management increases the indoor and visual comfort, health and productivity of inhabitants and users and is crucial to avoid overheating in nearly-zero energy buildings. 

In order to achieve the green energy targets, solar shading solutions should be integrated as a concept by architects and builders in all designs for both new sustainable buildings as well as refurbishments.

Year-long scientific study shows that manual operation of shading does not help: human behaviour collides with efficiency. Automation is the answer, both for saving energy and for optimizing natural daylight. Read the summary of the Swiss ESTIA study here.
