IEA SHC Task 56: Cooperation on Energy Balance and Building Design Tools

Submitted by Baerbel Epp on October 5, 2017
Task 56 meetingFacades of residential and tertiary buildings offer enough space for daylight control and HVAC (heating, ventilation and air conditioning) systems. Active envelope solutions include facade-integrated solar thermal collectors, PV panels, daylight control systems or panels containing ventilation units with heat recovery and/or a heat pump with all necessary connectors. Optimising their performance and building integration has been one of the main objectives of an international research programme called Building Integrated Solar Envelope Systems for HVAC and Lighting, also known as Task 56 of the IEA Solar Heating and Cooling Programme. The photo shows the around 20 task experts who met at Eindhoven University of Technology, Netherlands, on 21–22 September.

IEA SHC Task 50: LightingRetrofitAdviser.com for Investors and Planners

Submitted by Baerbel Epp on April 6, 2017
IEA SHC Task 50A redesign of lighting systems in office or public buildings helps to save electricity and improve lighting quality, as the office building of the Austrian company Bartenbach on the photos shows. However, lighting systems are rarely upgraded: For example, in Germany, retrofits can only be found in 3 % of the existing building stock and 75 % of lighting systems are out of date, as they are older than 25 years. To support planners and investors in their decision on what would be the most apt lighting retrofit, the researchers of Task 50 of the IEA Solar Heating and Cooling Programme, Advanced Lighting Solutions for Retrofitting Buildings, have launched a website called www.lightingretrofitadviser.com and an app for Android and iOS devices. Both provide stakeholders with information about successful case studies of lighting retrofits in buildings, a database of technologies as well as tools, for example, to give direct onsite support for decision making, whether it is sensible to retrofit a lighting system. A webinar on 21 March explained all the services and features of the new website and app. A recording of it is available online.
