This paper examines the energy profile and construction approach for a low-carbon house modeled on a structure built at Grand Parade, Brighton. It begins by analyzing Brighton's oceanic climate, including monthly temperature and precipitation data, to establish heating requirements. The paper then identifies appropriate sustainable construction materials — including insulated prefabricated panels, waste paper, hemp, straw, and reclaimed materials — suited to Brighton's heat-retention needs. Finally, it reviews relevant UK standards, particularly the Code for Sustainable Homes (CSH) and BREEAM framework, and outlines best practices in sustainable construction covering environmental, social, and economic dimensions.
The focus of this study is the energy profile of a house identical to the one constructed at Grand Parade, Brighton — an energy-efficient house built from waste materials. The local climate will be considered alongside the standards and best practices relevant to sustainable construction in the UK.
Brighton is reported to have an oceanic climate, much like the majority of southern Britain. During the summer months, sea breezes lower temperatures by approximately five degrees compared to inland areas. Snow is common in Brighton during winter. The table below shows monthly average high and low temperatures and precipitation throughout the year.

As the monthly average temperatures indicate, there is very little need for cooling in Brighton. The need for heating, while consistent, does not require a sustained high output — rather, it requires only enough to maintain comfortable and healthy indoor temperatures. Heating provision in Brighton is therefore primarily focused on retaining heat once the optimal temperature level is achieved. This means that building construction in Brighton should incorporate materials and design features that create heat pockets to maintain a building's internal temperature.
Construction materials suitable for this type of project include a skyharvester — a natural light source — as well as lightweight prefabricated panels with a high level of insulation. Insulation is constructed from waste paper and timber sourced from local sustainable suppliers. Heavyweight prefabricated panels make use of waste materials including hemp, glass, earth, reclaimed tins, straw, and carpet tiles.
The Code for Sustainable Homes (CSH) became operational in England in April 2007. From 1st May 2008, a minimum of Code Level 3 has been required for all new housing promoted or supported by the Welsh Assembly Government or its sponsored bodies. From 2nd June 2008, Code Level 3 is also required for all new self-contained social homes. The CSH is an environmental assessment method for rating and certifying the performance of new homes, based on BRE Global's EcoHomes scheme. It is a government-owned national standard intended to encourage continuous improvement in sustainable home building. It operates on a rating scale of one to six stars — Code Level 6 being the government target for 2016 — and contains mandatory requirements in key areas such as energy and water. BRE Global acts as advisor on issues related to the maintenance and development of the CSH's technical content, and manages implementation of the scheme under contract to the Department of Communities and Local Government (DCLG).
