East Bridgford Project Existing Projects The Green Box Project Adaptation Techniques used within this project:- Natural ventilation is increased by a passive cross ventilation regime seen in figure 1.2. This method enables the residents to encourage passive cross-ventilation through the movement of air across the building from the south side to the north side through the openings of windows, doors or vents. Monocrystalline Photovoltaic roof panels are fitted onto the south facing roof slope that is rated at 1.26kW peak. They are predicted to deliver 1,050kWhrs of electricity per year displacing 590Kg CO2 annually. Rainwater Harvesting is collected from the roof and is stored in a water tank with a capacity of 1100 liters capacity seen in figure 1.3. A low grade electric underfloor heating system is embedded into the concrete floor slab which is thermostatically controlled. In replacement of a central heating boiler there is no pipe work, radiators, boilers, fuel and none of the associated emissions. The Green Box is a project adapting an existing building, 21 The Street, Ringland to a low carbon house that will encourage a sustainable future in reducing the effects of climate change. This is done by decreasing its greenhouse gas emissions, energy, water and waste costs. Through modifying the buildings fabric, enclosing the external walls with insulation and increasing the buildings thermal capacity will help solar gains and reduce the rate of heat transmittance. Therefore, the buildings heating load necessity is reduced while sunlight and daylight level are increased. Figure 1.1 shows the rearranging of the windows to the south, contributing to the availability of passive solar heat gains, while glazing on the north side is diminished to reduce heat losses.

Honingham Earth-Sheltered Social Housing Scheme East Bridgford Project Existing Projects This project shown in figure 2 is UKs first earth sheltered social housing scheme that is a four, single story, two bedroom dwellings in Norfolk village of honningham. Each building has a high thermal mass structure, are very well insulated and are orientated south. These characteristics have enabled some of the households to reduce their total annual energy consumption significantly. Use of specific energy saving techniques and minimal environmental impact:- Orientating the buildings around the suns path has ensured maximum solar gains and enhanced daylight is achieved. Each building is landscaped into its natural environment. Each individual room is one room deep ensuring all rooms take full advantage of the solar gains. The building is adapted for the use of renewable energy sources and enhanced the local environment. Each building is equipped with its own energy efficient task lighting which can be adjusted to suit individual requirements. Rationalising the construction process:- Carbon emissions were reduced by the decrease of subterranean excavation (the material removed from the ground below). 80% of materials used throughout the constriction process contained recycled ingredients. These included bottom furnace ash, woodchip and pulverised fuel ash. Extensive use of cavity walls, skirting boards, architraves, stud walls, plasterboard, plastering and roof voids ensures a faster, more cost effective construction process. Figure 2
