Renovating Historic Buildings To Zero Energy

Deep Renovation of Historic Buildings Towards Lowest Possible Energy Demand and CO2 Emission (NZEB)

Historic buildings make up a considerable part of our building stock (one fourth for Europe). They are the trademark of numerous cities, and they will only survive if maintained as a living space. This means, that in order to save this heritage for future generations, we need to find conservation compatible energy retrofit approaches and solutions, which allow to preserve the historic and aesthetic values while increasing comfort, lowering energy bills and minimizing environmental impact.

In the last 10 years a shift in paradigm could be observed: While in times of the first EPBD, a strong opposition from conservators and architects could be observed – “don’t touch these buildings” – there is growing a new openness, a much more constructive approach – “let’s find the right solutions together”. Examples for this development are last but not least the installation of the International Scientific Committee on Energy and Sustainability within ICOMOS and the development of “Guidelines for improving the energy performance of historic buildings” (EN16883, now under final vote) by the CEN TC 346 on Conservation of Cultural Heritage.

Now is an important moment to identify and promote good approaches and solutions.

What's New
  • Producing hot water underneath natural slates - A state-of-the-art solar thermal system has been installed under the slate roof of a castle in Ghent, Belgium. Roll-bonded Thermoslate absorbers measuring 44 m2 have been integrated into the space between the wooden trusses and natural slate tiles of the historic structure built in the 12th century and cannot be seen by visitors.

  • New standard to improve energy performance of historic buildings - Maintaining the exterior of a historic building while raising energy efficiency is not necessarily a contradiction. The new EN 16883:2017 standard, Conservation of cultural heritage, provides guidance on how to improve the energy performance of historically significant structures. (Posted: 2018-08-25)
  • How to Turn Historic Structures into Nearly Zero Energy Buildings - More 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. (Posted: 2018-04-09)
