On October, 18th, PRACSIS coordinated and organised a European Commission event on electronic and web-based tools for energy efficiency. An increasing number of Intelligent Energy Europe and Horizon 2020 Energy Efficiency projects use electronic and online tools in their activities. The event brought together all current European initiatives on buildings, heating and cooling to create synergies and support exchange of expertise. The event was the opportunity to gather experts and discuss the most available manner to deploy electronic tools in the field. Testimonials came from a wide range of invited experts from the European Commission, research institutes and universities, and private companies. PRACSIS was in charge of online registration, travel arrangements, logistical support to the Commission’s Executive Agency for Small and Medium Enterprises (EASME) on the coordination of simultaneous break-out sessions. PRACSIS furthermore leads the publication of a best practice guide on tools for professionals, for policy-makers, and consumers. The report will be accessible through our project BUILD UP.
