Recent Work


Detailed below are summaries of some of the SAP calculation work that has been undertaken recently.


South London Development

SAP calculations for a development of over two hundred flats, and terraced houses in South London. The riverside scheme is to have heating and hot water provided by a ground source heat pump system and will provide dwellings for the private, rental and shared ownership sectors.


Herefordshire Social Housing Scheme

SAP calculations for a mixed development of a dozen timber framed dwellings in a Herefordshire market town. The scheme is using electric heating and hot water, with the hot water provision augmented by roof mounted solar panels.


Sheltered Residential Housing Development

Home energy ratings for fifty dwellings in a block of sheltered housing units for the elderley, located in Birmingham, for a national care provider. The scheme is having a community heating system and SAP calculations have been undertaken in association with a firm of consultant mechanical engineers tasked with providing energy ratings for the non-residential areas of the building, in order to demonstrate building regulations compliance for the development as a whole.


Code for Sustainable Homes Level 3 - Mixed Development

Assistance with developing a design specification to reach Code for Sustainable Homes Level 3 on a mixed development of flats and houses in Lincolnshire. The scheme is to include solar water heating for the houses and flue gas heat recovery systems and mechanical ventilation with heat recovery, to the flats.


SAP Calculations For Major National Housebuilder

In conjunction with other locally based associates we shall now be providing SAP calculation services on a regular basis to a leading national volume housebuilder on a selection of large new build sites in England and Wales.


1950s House Refurbishment in Malvern

Work on a project to refurbish an energy inefficient detached dwelling built in the 1950s in Malvern to a highly energy efficient one. In support of the client and the architect we will be using the NHER Plan Assessor software to establish a baseline SAP calculation for the existing dwelling and will then use the software to model and inform design choices which are likely to include increased levels of insulation, new heating and hot water systems (to include Solar Hot Water heating and a Ground Source Heat Pump), improved ventilation and more energy efficient lighting provision.
