We aim to build environmentally sustainable buildings and embed sustainability into the management of our estate. Any new building or refurbishment is planned, built and occupied to ensure the greatest energy and water efficiency and lowest carbon emissions possible. The Eastern Gateway Building (completed in May 2012) was rated BREEAM Excellent.
Current initiatives include:
- Replacement of inefficient lighting with low energy sources and the provision of lighting controls.
- Installation of a combined heat and power unit supplying electricity and hot water to the Isambard complex
- Provision of enhanced thermal insulation to flat roofs during the periodic replacement of roof coverings.
- Improvements in the Building Management System
The Estates Department aims to promote a sustainable future through leadership and good practice by:
- reducing energy use and carbon emissions by investing in cost effective efficiency measures.
- ensuring operational staff are suitably trained and are updated as necessary to achieve the best possible return on investment in energy efficiency measures.
- exploring the opportunities for exploiting alternative fuels and new technologies.
- seeking to achieve BREEAM 'excellent' or 'very good' ratings for new University buildings. Incorporating energy efficiency measures into annual building maintenance and refurbishment programmes where practical.
Practical measures include:
- Land use: Materials from demolished buildings are recycled to minimise landfill.
- Aggregate use: Specification of recycled aggregates for new concrete structures and recycling of excavation for landscaping.
- Water conservation: Installing water efficient devices such as waterless urinals and spray taps. Recycling rain water for toilet flushing.
- Sustainable building materials: The use of materials with low embodied energy and glazing with low E coating materials are selected for high durability and low maintenance. Prefabricated elements are used to cut down wastage.
- Energy efficient design: The use of natural ventilation to cool buildings. Reducing glazed areas and orientating buildings to minimise solar gain. Buildings are designed to meet and go beyond the new Part L regulations to enhance energy efficiency. Ultra-efficient heating and lighting systems
- Renewable energy technologies: Consideration of feasibility studies to install alternative energy systems such as solar PV cells, heat pumps and wind turbines.
