The default answer when you want to do pretty much anything to a listed building is ‘no’. The default assumption if you want to achieve the Enerphit standard for retrofit is ‘tackle everything’. So how on earth do you retrofit a listed building to within a whisker of the Enerphit standard — with the blessing of the conservation officer?

Architecture practice vHH has announce that it is planning to adopt the passive house standard on a three-storey extension to the Grade 11 listed Leicester Cathedral, which is due to start on site in July 2019.

When it came to upgrading an old stone-walled building to the Enerphit standard — with all the inherent challenges such an upgrade poses for energy, airtightness and moisture — who better to have as your client and defacto site manager than a professor of physics?

This pioneering upgrade project, completed in 2009, turned a Victorian redbrick in Birmingham into one of the UK’s greenest homes. Along with a much wider ecological agenda, the house employed fabric first principles of insulation and airtightness, and met passive house design targets at a time when the standard was still in its infancy in the UK.

Most energy upgrades to historic homes in architectural conservation zones take a fairly gentle approach to insulation and airtightness — this one did the exact opposite.

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.
