Brief
EcoConsulting
was appointed to carry out the SAP energy
ratings and the EcoHomes assessment of a
104-unit residential new built.
Our consultants conducted the SAP
assessments, and all of the penthouse flats
were failing Part L Building Regulations in
the initial analysis. We had to re-assess a
variety of different options in order to
find, flat by flat, a viable solution to
achieve compliance. This proved difficult
given that the development was almost
completely built, and given the client’s
budgetary constraints and planning approval.
Indeed, given that the planning approval had
already been obtained, the design could not
significantly change without having to ask
for another planning permission, which was
unrealistic at this stage in the
development.
We evaluated various alternatives and
combined different options to achieve Part L
compliance, including: increased insulation,
additional water tank insulation, installing
a geothermal heat pump, installing solar hot
water panels, improving glazing u-value
performance, and replacing the glazed
curtain walling with filled-in and insulated
panels. We also advised on the cost
implications of each alternative seeking
quotes from manufacturers where requested.
The final solution combined replacing part
of the glazed curtain walling with solid
panels to improve the overall u-value of the
wall, additional roof insulation, and the
installation of air-to-air heat pumps in the
livable areas (i.e. living rooms and
bedrooms). |
