Code for sustainable homes: case studies volume 2 - Gov.uk

BUYER/OCCUPANT
FEEDBACK
At the time of this research, none of the units
was occupied, so post-occupancy information
was not available. Feedback from the London
Quadrant Housing Association has been
positive, and they are pleased with the final
design of the units and the environmental
features integrated into them.
LESSONS LEARNT
The main lessons learnt from the development
have been:
• Having an in-house Code assessor is an
effective way of ensuring that the Code
requirements can be achieved in the most
cost effective way as well as ensuring the
post-construction evidence requirements
can be easily collated and submitted
• Achieving the minimum mandatory energy
credits for Code Level 3 typically requires
the use of renewable energy generating
technologies. Although the achievement
of a 25 per cent reduction in dwelling
emission rates is possible without using
renewable technologies, this is difficult
on flats and terraced units as they are
already inherently energy efficient
• Solutions to achieve Code Level 3 at
one development can be used on other
developments. For example, the Home User
Guide at Tempo can now be used as a
template document on other schemes
• Building homes with lower lebels of air
permeability may require additional training
for on-site operatives and design teams in
order to ensure that construction details
are designed and built correctly
