Background
The first project was developed by Pembrokeshire Housing Association’s (PHA) and
consists of six four-person (two bedroom) houses on Britannia Drive, in Pembroke Dock
built to Code for Sustainable Homes level four. The project was one of twenty-two
schemes which used a portion of the Social Housing Grant programme to assess the
implications of building to higher standards of the CfSH and inform the timetable for
achieving the aspiration for all new homes to be zero carbon (Welsh Government 2011).

The six units in Pembroke Dock were built using timber frame construction, infilled with
insulation, with a rendered blockwork outer skin and photovoltaic (PV) panels mounted
on the roof. This construction represents a ‘tried and tested methodology’ of PHA and
has been used on almost all of their house design over the past five years. The pilot
project was not prescriptive about how each development should achieve the target of
CfSH level four or higher, which allowed PHA to meet the requirements by using PV
panels to upgrade a standard house design.
