This was one of the main messages of the International Workshop on the Status of PVT Systems, organised by Fraunhofer ISE on 16 May 2018 in Freiburg. The event, held as part of IEA SHC Task 60, Application of PVT Collectors and New Solutions in HVAC Systems, featured 15 speakers, who updated 63 attendees working in industry and science on the progress made with PVT products and research.

Position Paper: Actions Needed to Pave Way for Net Zero Energy Buildings

Submitted by Baerbel Epp on August 3, 2015

Over 40 % of primary energy use and 24 % of greenhouse gas emissions are attributed to global energy use in buildings so architects and builders are being posed the challenge of creating highly energy-efficient structures. One vision promoted by stakeholders in many countries worldwide is Net Zero Energy Buildings (NetZEBs). To provide an analysis of the market potential and the actions required for a market uptake of this architectural design approach, the IEA Solar Heating and Cooling Programme published a position paper entitled SHC Net Zero Energy Solar Buildings in June. The 10-page summary is based on the insights of 82 experts from 19 countries, who have been conducting research within a joint IEA SHC Task 40 and Annex 52 of the Energy in Buildings and Communities Programme (EBCP) over several years (see the attached document). The photos show three French NetZEBs: a university research building on the tropical Island of La Reunion, an office building in Paris and a school in the city of Poitou‐Charentes.
