solar gain. Mechanical Cooling will be required in the retail unit, as heat gains from lights
and equipment will be more significant. However, further details of the approach adopted
to minimise cooling demand in the non-domestic buildings should be provided.

Renewable energy technologies (policy 4A.7)
87 Across the phases, the applicant is proposing to install 392 sq.m. of photovoltaic cells
(PV), reducing overall emissions by 1.6%. While PV is compatible with the use of CHP, the
overall reduction achieved from renewable energy is low, especially when compared
against the London Plan 20% target. The applicant is, therefore, asked to consider
whether there is further scope to install more PV within the development, perhaps as part
of a phased approach.
88 In terms of renewable heat technologies, it is accepted that solar thermal will compete
for the base heat load supplied by the CHP and biomass boilers would adversely affect the
air quality in the vicinity of the development (which is located within an air quality
management area). It is also acknowledged that other on-site renewable technologies are
not suitable for this development given its particular characteristics.
89 The proposals are broadly acceptable in principle subject to further information being
provided to ensure compliance with London Plan policies 4A.5, 4A.6 and 4A.7.
Sustainable design and construction (policy 4A.9)
90 The London Plan promotes five principles in policy 4A.9 to promote and support the
most effective adaptation to climate change. These are to minimise overheating and
contribute to heat island effects; minimise solar gain in summer; contribute to flood risk
reduction, including applying sustainable drainage; minimising water use; and protect and
enhance green infrastructure. Specific policies cover overheating, living roofs and walls and
water. The London Plan Consultation Draft Replacement Plan also includes policies to
ensure the development makes the fullest contribution to London’s adaptation to climate
change.
91 The applicant has assessed the proposal against London Plan policy and the
sustainability assessment checklist from the Mayor’s Essential and Preferred Standards in
the Sustainable Design and Construction SPG and the results of this are generally
acceptable.
Local planning authority’s position
92 Brent Council is currently reviewing the proposals but supports the principle of the
estate redevelopment.
Legal considerations
93 Under the arrangements set out in Article 4 of the Town and Country Planning (Mayor
of London) Order 2008 the Mayor is required to provide the local planning authority with
a statement setting out whether he considers that the application complies with the
London Plan, and his reasons for taking that view. Unless notified otherwise by the
Mayor, the Council must consult the Mayor again under Article 5 of the Order if it
subsequently resolves to make a draft decision on the application, in order that the Mayor
