We plan to operate the development so that, the net emissions of CO₂ are zero.

The redevelopment of Clegg Hall Mills incorporates a number of measures to reduce energy use in the individual apartments and the houses. Achieving lower energy consumption will result in lower running costs for the home owners compared to operating a similar dwelling without the energy efficiency features.

As well as saving the owner money on fuel bills, the energy efficiency measures will reduce CO₂ emissions. It is estimated that the resultant overall CO₂ emissions from the domestic accommodation will be reduced by over 50% compared with a more conventional development.

As well as operating with lower energy demand, Clegg Hall Mills will incorporate it's own 'green' generating plant to ensure that the energy consumed in the building will be supplied mainly from renewable sources. This will mean that emissions of carbon dioxide (the main greenhouse gas) from the Mills will be very low. It is planned to operate the building so that, on an annual basis, the net emissions of CO₂ from the domestic properties are zero.

A basic description outlining some of the proposed renewable energy systems for Clegg Hall Mills are as follows:

• Integration of Ground Source Heat Pumps using heat from external ground collectors laid within adjacent lake.
• Intelligent control systems for energy efficient heating and hot water.
• Underfloor heating throughout for high efficiency heating.
• Low energy lighting and electrical appliances.
• Heat recovery ventilation systems.
• High efficiency gas condensing boilers.
• High thermal mass through the retention of the existing concrete and thick walls, reducing overheating in summer and retaining comfortable temperatures during winter months.
• Individual metering for all dwellings.
• High insulation exceeding target 'U' values.
