Evidence review assessing the potential energy savings from the increased application of heating controls in residential properties across the European Union
This report, prepared for eu.bac (European Building Automation and Controls Association), once more emphasises the need for more action on home heating controls.
"This study confirms what industry has always believed and should serve as a ‘wake-up call’ to those who have neglected the importance of heating controls as an energy saving measure." said Gerhard Glinzerer, the chairman of the eu.bac residential sector group. "From the perspective of policy makers this is not so much low-hanging fruit as a windfall – a huge potential for energy savings from existing, low cost and readily available technologies that has not before been properly quantified."
eu.bac believes that it should be a priority to ensure that every home in the European Union has individual room temperature controls to reduce waste while delivering comfort, plus central time and temperature control so that the space heating appliance will run as efficiently as possible. The association will continue to work with the European Commission to show how the Ecodesign and Energy Labelling Directives can be utilised in conjunction with the Energy Performance of Buildings Directive to provide a much stronger regulatory framework that can bring the benefits of these cost effective technologies to every European citizen.
The study was carried out by an independent consultancy, Paula Owen Consulting based in London. This report presents an evidence-based assessment of the potential for energy and carbon emission savings through the appropriate installation and use of heating controls in all residential buildings throughout EU member states. This estimation of the potential for heating controls savings runs from the present day out to the year 2030. The assessment encompasses the potential at the individual country level as well as a total potential for the whole EU region. The resulting spreadsheet tool developed as the principal output of this project used the assembled data and evidence to define the housing stock in the EU-27. This included metrics such as the total floor area, the heating fuel mix, average useful heat demand and the current penetration of heating controls. These data sources were combined to form a snapshot of the present day situation in countries across the European Union.
From the starting point of the base year the tool uses a simple stock model to estimate how the efficiency of each country’s heating systems will improve as controls are installed.
This allows the calculation of the delivered energy for space heating in each country in future years, and by comparing a scenario of increased control installations against a baseline of business as usual (BAU) it is possible to calculate the difference in delivered energy and, consequently, the CO2 emission and fuel bill savings.
