New standard to improve energy performance of historic buildings

The new EN 16883:2017 standard, Conservation of cultural heritage, provides guidance on how to improve the energy performance of historically significant structures. A group made up of 45 experts from 12 countries had mapped out the guidelines for six years before they were published by the European Committee for Standardisation in June 2017. Researchers working for the IEA Solar Heating and Cooling Programme, also known as IEA SHC, are now on the lookout for suitable case studies to evaluate processes and assessments proposed in the standard.

IEA SHC: How to Turn Historic Structures into Nearly Zero Energy Buildings

Submitted by Baerbel Epp on May 17, 2017
Villa CastelliMore than one-fourth of all residential buildings in Europe date from before 1945. Over the past decade, preservationists have taken to the idea of renovating historic structures in an energy-efficient manner. The planned IEA SHC task titled Deep Renovation of Historic Buildings Towards Lowest Possible Energy Demand and CO2 Emission intends to find the best solutions to this challenge. The photo shows the Villa Castelli at Lake Como in Italy. The energy requirements of the building have been reduced and the remaining demand has been met by a heat pump and PV-generated electricity.
