A HISTORIC RETROFIT – WHY IT MAKES COMMERCIAL SENSE TO UPGRADE EXISTING BUILDINGS

 

The success of this project can be measured in the reduction of the Energy Performance Certificate from E to B and an increase in the rental value of 75%, justifying the investment by the landlord and attracting a new and very happy tenant.

The original architect is unknown but the building, built in 1888, presents layers of historical significance in the architecture, technology and human activity that has taken place here. Therefore a conservation approach has been taken in developing concepts for how best to retrofit the fabric of the roof, interior and whole new servicing infrastructure, whilst preserving and enhancing its character. Several significant alterations were made to the building, particularly in the years of occupation by the Rifles. Not least after damage caused by a bomb dropped from a Zeppelin in 1915!

A HISTORIC RETROFIT – THE E2 WAY; A CONTEMPORARY CONSERVATION APPROACH

 

Super low-g glass with reduced transmittance but a clear appearance in pre-glazed aluminium units that preserved the sightlines were specified. The concrete tiles were replaced with manmade slates (natural slate was too heavy). Beneath, multifoil insulation was integrated over the historic sarking boards to reduce heat gain as well as insulate.

All parapet gutters and flat roofs were insulated with warm roof liquid applied covering. Air tightness was improved at all junctions. This, with the removal of gas and installation of MVHR and ASHP, and full LED lighting, resulted in the EPC for the building being reduced from E to B, achieving PAS2038.

A HISTORIC RETROFIT – JOIN US ON A GUIDED TOUR OF THE BUILDING

 

We have already held two events with interested industry professionals, where we offer an in-person presentation by E2 Director Sam Cooper and Associate Jim Rooney digesting the project, its complexities and its successes – and revealing our approach to retrofit, founded in our ‘Contemporary Conservation’ approach, all whilst guiding you through and around the building.

If you would like to find out more about this project – and indeed join us for a tour, discussion and some refreshments afterwards – get in touch.
