How to design a Low Carbon House? | House Design
In this article, we will study the climate of the city, orientation of the structure (Waste House), building design and low energy specifications
Location of Waste House
The Waste House is located in Brighton, a town on the south coast of Great Britain. It is situated in the southeast side of Grand Parade campus of the University of Brighton.The low carbon house project is located in the southeast side of the Grand Parade campus of the University of Brighton.

Brighton has a temperate climate characterised by mild, calm weather and is sunny in summer, sea breezes and a healthy, bracing air.
Climate Data
According to the statistics provided by (Climate and temperature, 2012), we have almost 4.8 hours of sunshine per day which equates to 1766 hours of sunshine annually. Storms occurred in the years 1703, 1806, 1824, 1848, 1850, 1896, 1910 and 1987 caused serious damage. Also there have recent storms in December 2013 and February 2014 causing fierce wind and floods (The Guardian on ‘UK storms and flooding’, 2014).
Orientation
Waste house is a two storey house. Achieving energy efficiency is the key objective of the project. One of the most important design considerations is achieving optimum orientation of the building in order to achieving optimum energy efficiency.
The southern wall of the waste house will have windows and roof angled at approximately 35° to help in maximizing the solar gain in winter and take advantage of the elliptical solar path (Halliday, 2008 and Pitts and Lanchashire, 2011). Since, the building lies in the central location of the town, it is surrounded by buildings.
Low Carbon House Design Methodology | Part 2

Stepwise procedure for designing the low carbon house
Step One
Identifying nationally recognized methods for assessing the environmental performance of new buildings in the UK.
Most widely used methods include Code for Sustainable Homes (CSH) 2006 and British Research Establishment Environmental Assessment Method (BREEAM). Other methods include Association for Environment Conscious Building (AECB) Silver and Gold and PassivHaus.
Policies for Sustainable Development in Brighton and Hove
The City Plan Policy CP8 for Sustainable Buildings supported by Supplementary Planning Documents, SPD 08 – Sustainable Building Design is expected to deliver viable development that considers community aspirations, environmentally sensitive, high quality, adequate infrastructure and helps in mitigating the impacts of climate change by gradually transitioning towards achieving a low carbon economy (NPPF, 2012).
National Planning Policy Framework, 2012 expects the local plan policy to play an active role in guiding the development that is viable and sustainable. The principles of One Planet approach have been adopted by the Brighton & Hove City Council which aims at radical reductions in greenhouse gas emissions by reducing energy consumption before the construction and after it is built. Mitigating the impacts of climate change is an important aspect of delivering Sustainable development (Low Carbon Construction, 2010).
Her Majesty’s Government proposed Climate Change Act in 2008 which was the world’s first long-term legally binding framework to tackle the dangers of climate change. It include a statutory commitment to reducing the carbon dioxide emissions by 34% by 2020 and 80% by 2050.
Step two
One Planet living principles
It provides a framework that helps us examine and evaluate the sustainability challenges that we face and develop action plans in order to create a sustainable and healthy environment.

The ten principles are as follows:
- Zero Carbon
- Zero waste
- Sustainable transport
- Sustainable materials
- Local and sustainable food
- Sustainable water
- Land use and wildlife
- Culture and community
- Equity and local economy
- Health and happiness
Waste House Construction, Brighton, UK

Case study of Waste House in Brighton | Grand Parade Campus
Waste House is being constructed in the Grand Parade Campus of University of Brighton. Brighton is town in the southeast of England, UK. Duncan Baker Brown and Cat Fletcher are leads in the project. It is a challenging project. This house is going to be used as a studio for postgraduate design students. It will be open to public for viewing. The aim of the project is to demonstrate how waste can be efficiently used for the construction purposes without having to compromise on the quality.

Materials selected for the Waste House Project
Roof – solar roof (Solar PV tiles have been used on the roof.)
Sky harvester – Natural light source
Rainwater harvesting
Timber from local sustainer sources
Second hand timber
Since it is second hand timber and that its strength cannot be determined, the structural engineer assumes that the timber is of the weakest type and compensates in the design accordingly.
Walls
Lightweight prefabricated panels = lots of insulation
Reuse waste materials such as Hemp, glass, earth, tins, straw, carpet tiles
Heavy weight prefabricated panels = lots of heat storage
Chalk wall – 10 tonnes of chalk used + 10% clay
(Although only 100% chalk would mean better wall strength)
