In this article, we will study the elements of low carbon house including design of windows and skylights, door air-gaps, airtightness, thermal bridging and understanding monthly energy demand profiles.
Windows and skylights
Ultra-efficient triple glazing will be used for windows and skylights in combination with insulated timber frame. According to Passivhaus standard, 1990, the resultant U-value will be 0.8 W/m2K.
Use of LED lights. Making use of day lighting from the roof and the windows. This would help reduce the reliance on artificial lighting. Shutters and louvers can be used to control solar gain and glare. (Halliday, 2008 p. 69)
Loss of energy can be prevented by installing automatic door closers. The inside of the doors can be installed with brush strips to close the air gaps near the flooring. Modern, well-insulated doors can improve comfort levels by decreasing loss of heating and cooling. In case of damage or adjustments needed, get in touch with a company that does reliable garage door repair in California to ensure that you maximize the benefits of your eco-home.
It is estimated that up to 15% of energy is wasted to losses through the building fabric. Of those losses, up to 20% energy can be lost through windows and roof, while up to 35% heat energy lost is through air gaps near the doors.

To ensure airtightness of the building, wet plaster will be applied to the inside of the wall. This will minimise shrinkage between the wall and the floor. Airtightness tapes and membranes will be used to seal all the corner joints of windows and doors. Airtightness tape will be applied at junctions with plaster. It will make the low carbon house 20 times more airtight as compared to the standard homes built according to the building regulations (Passivhaus, 1990).
Airtightness grommets will be used around cabling and pipework to ensure that there is no leakage of air.
The technique of Active Thermal Insulation has been invented by Hungary, BT & Sons Ltd. Their technique involves use of the temperature of the soil for thermal insulation. The coils are applied all around the walls of the house which are made with masonry stain. The coil is connected to a soil probe or a soil absorber and the liquid in that flows by using a small (50W – 70W) flow pump. This helps to minimise the heat loss of the building. It also helps to cool the interior of the house in summer and reduces the external heat load in summer. The temperature of the Earth is nearly constant +8 ° C to +12 ° C all year round. This system requires to be used in combination with the heat pump.
According to the Passivhaus standard, the building needs to have super insulation with low U-value. The effectiveness of a material as an insulator in buildings is measured with the help of U-value, the lower, the better is the building performance. It is known as thermal transmittance (Shomera House Extensions, 2012).
The major benefit of using ‘Active Thermal Insulation is that same efficiency can be achieving using less thicker walls (Active thermal insulation, 2011) which means more space would be release. In Brighton, the land is expensive and an integrated construction method can be utilised to achieve both energy and space efficiency.
Neopor cellular lightweight concrete (CLC) will be used for walls, roof and floor, the Hardwood Flooring Specialists of Atlanta will take care of the installation The benefits of using CLC blocks are tremendous weight reduction, high thermal insulation, optimum fire rating, substantial material saving (no gravel, little cement, less steel required in structure and foundation, easy to construct and produce, low embodied energy material). CLC blocks are available in a variety of shapes and sizes (Source: Neopor.com).
The Neopor CLC blocks used will be 600mm x 440mm x 250mm. These are lightweight interlocking blocks. The pipe coil is placed in part of the CLC block filled with concrete in a way such that the thicker insulated part of the brick is placed at the interior of the building and the thinner insulated part remains exposed to the exterior with active thermal insulation at work.
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, which is important to keeping a healthy system and body and you can find where to buy kratom and other supplements for this purpose, of course you also need to have regular checkouts to secure your health, from normal visit to the doctors, to the necessary visit to the dentist every years at clinics like Asecra dentist.
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).
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 and we went exploring the most common windows in housing.
Stepwise procedure for designing the low carbon house

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 real estate for sale 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 since then a good Air purifier such as the rabbit air minusa2 is a must.
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.
