Nottingham radical retrofit
Gil Schalom Design undertook a radical whole house refurbishment on a 2-bed Victorian house in Nottingham, with the help of a number of 21° products, including MVHR system, airtightness products and triple glazed timber windows. At the design stage, the project has achieved an impressive space heating requirement of 18.77 kWh/m2/annum and peak total heat loss of 1.6 KW.
As the house is within a conservation area, the majority of the energy efficiency measures were applied internally to preserve the exterior appearance. Designed using Passivhaus Planning Package (PHPP), the house has 500 mm insulation in the loft, up to 270 mm on the walls and 250 mm in the ground floor plus triple glazed windows with insulated frames. Two airtightness barriers plus a lot of attention to detail have made it possible to avoid the need for central heating.
MVHR system
21° designed, supplied and commissioned the Focus 200 PAUL MVHR system for the project, offering over 90% efficiency.
