An energy strategy for a residential scheme in London

Abstract: This thesis will investigate the option to implement onsite renewable and
efficient energy systems in an urban area in the UK. This is in order to
lower the carbon dioxide emissions for a residential scheme that is being
developed at the Lots Road site in London. The energy strategy target for
the Lots Road site is to achieve a 50% reduction in carbon dioxide
emissions compared to utilizing fossil fuelled energy.

Energy system studies and a Lots Road site investigation were made in order
to gain understanding of the energy generation process and where they could
be placed onsite. Then an evaluation of the energy systems carbon dioxide
emissions and energy outputs were carried out with the purpose of finding
suitable systems for the Lots Road site. From the energy system evaluation
biomass, combined heat and power, solar water heating and photovoltaic were
selected as being suitable energy systems to be used at the Lots Road site.

The thesis shows that there are several options that could be implemented
into the energy strategy to achieve the 50% reduction target. The final
option is to use biomass fuel for thermal energy generation. It will be
burnt in biomass boilers in two energy centres on the Lots Road site. The
biomass boilers will be utilized to deliver the major part of the sites
thermal demand. It will be used together with on site roof based solar
water heating panels. The panels will help to deliver thermal energy for
the site. Roof based photovoltaic (PV) panels will also be put in place to
deliver electricity and will together with green roofs be used as
sustainable design features. The final option will achieve a carbon dioxide
reduction of 54.5%.

The use of biomass boilers, solar water heating and photovoltaic panels at
the Lots Road site are the most suitable energy strategy options. This is
because the selected renewable energies reduce the sites carbon dioxide
emissions and are available on sites across the UK.
