The Greengauge consultancy reports on its ‘deep retrofit of a heritage community-owned pub’.
Greengauge writes:
The Limpley Stoke Community Benefit Society (LSCBS) has succeeded in retrofitting its 16th century Wiltshire village pub, bringing it back into use, and into community ownership. The retrofit aimed to address urgent structural issues and improve the building fabric and thermal performance of the pub. The Hop Pole Inn has now reopened following the sensitive retrofit of the Grade II listed building, led by conservation architects James Sibson RIBA AABC, who led the capital works on the board for LSCBS, and Rhys Brookes RIBA AABC of Harrison Brookes.
Greengauge was part of the project team supporting the retrofit with modelling in PHPP (Passivhaus Planning Package), dynamic thermal modelling, 2D & 3D thermal bridging modelling, mechanical and electrical building services design and moisture risk analysis of internal wall insulation strategies, using WUFI modelling.
Strategy
Retrofitting a Grade II heritage building required considerable care and attention to find the right fabric and building services strategy that would work with the building. Examining the existing condition of the building and researching its construction was essential to avoid any unintended consequences from the retrofit. Greengauge carried out analysis of the building fabric and used the findings when modelling the building using PHPP to evaluate any proposed improvements. Greengauge also undertook moisture risk analysis to ensure that any proposed internal wall insulation strategies would be suitable. To find the right, proportionate solutions, the team engaged in detailed consultation with the manufacturers of natural lime based insulating plaster products and traditional plaster. Building services design undertaken by Greengauge also helped ensure the right ventilation and heating strategy for the project.

Hannah Jones, Director, Greengauge [said] ‘It’s not about whether we can, or should heat historic buildings with clean energy, or whether we can or should improve their thermal performance. It’s about thoughtful balancing of multiple competing priorities!’
