Thermal Bridging And Airtightness

E2 were selected by Kier Construction to undertake the SBEM calculations and EPCs on all of the units at the development to ensure Part L compliance was achieved on all proposed buildings at Princes Gate. A 3D model of each building was created using architectural drawings.

Our SBEM design team, using their extensive knowledge of Part L, proposed target U values for the fabric of the buildings. Most of the units were Shell and Core buildings so applicable generic Heating, cooling and ventilation systems (HVAC) were used in the calculations.

For the units having HVAC systems installed, specialist M&E contractors provided E2 with schematics and details of the systems, specifics were input into the calculations. E2 worked closely with Kier to ensure any changes in the proposed design were accounted for and any SBEM calculations amended.

At completion stage Part L compliance was achieved on all units. 23 passing BRUKL documents alongside 23 Energy Performance Certificates were produced and handed over before the designated deadline. This allowed for the development to be signed off by building control, Kier were much more than “Part-Ly” satisfied with our service.
