Building Design and Environmental Data
Description
The School of Chemical Engineering and Analytical Science (CEAS) is a University Faculty building comprising five floors of mixed teaching space, research laboratories, teaching laboratories and support accommodation. The interior is arranged either side of an atrium running the full height of the building. To one side of the atrium is an experimental 'Pilot Plant' area where industrial scale experiments can be undertaken across a number of floors. At the other side of the atrium are teaching labs, office spaces, staff areas, and research labs.
Environmental Data
A Design Stage BREEAM score of 64.48% has been targeted under the BREEAM Education 2006 assessment scheme. BREEAM credentials will be enhanced through the construction period to improve this score and rating.
The building services serving the CEAS building are designed to minimise energy usage and reduce the carbon emissions associated with the operation of the facility. Heating is to be provided to the building by a closed loop ground source heat pump, energy is extracted from the ground via an array of 24 bore holes drilled to a depth of 150 m, this energy is converted to higher temperature water within the heat pump which is then circulated around heating loops embedded within the concrete floor slabs to provide heating to the building, during the summer months the heat pump can be reversed to provide cooling to the laboratories in order to limit the peak internal temperatures. See here for more information on the ground source heat pump
High efficiency lighting and controls will be installed across all areas of the building ensuring that only those areas in use are illuminated, whilst maintaining lighting levels along escape routes from occupied areas.
In the new building, rainwater is harvested from the roof areas and utilised for flushing toilets and urinals within the building. It is predicted that the installed rainwater systems will reduce the total volume of water used within the building by 60%.
Construction Phase Reduction of Environmental Impacts
- Water recycling when drilling ground source heat pump.
- Plunge taps fitted to wash hand basins in temporary site facilities.
- Passive switches to lighting in site office.
- All timber used on site from renewable source.
- Concrete demolished on site crushed, graded and reused on site.
- Off site manufacture of Mechanical and Electrical works to be delivered and installed in manageable units and modules.
- Segregation of waste materials.
