9 SUSTAINABILITY The key aim of the project is to create sustainable, grade A office space with an excellent working environment. The existing façade is to be retained, although aesthetically improved. Services are to be completely replaced with a new energy efficient design and controls. A great deal of focus has been placed on the working environment, as well as the creation of cycle parking and shower facilities. The building is targeted to achieve a BREEAM rating of Very Good under the BREEAM 2008 for Offices Scheme. The building is expected to achieve an EPC B rating. Below are some of the key sustainability measures for the project: Monitor, report and set targets for CO 2 emissions or energy arising from energy consumption, transport, water related to construction activities. Use of principal / main contractor who operates an Environmental Management System (EMS). Energy efficient air source heat recovery heat pumps as part of a VRF (variable refrigerant flow) air conditioning system. This matches the flow rate of refrigerant to the required heating or cooling loads, thereby saving energy and providing more accurate control than the previous VAV (variable air volume) system. The use of heat recovery type units further improves the efficiency of the VRF system by using the byproduct of cooling and heating to transfer energy within the occupied space where it is required. Energy efficient lifts, with a standby mode that automatically switches off lighting and ventilation when the lift is not being used. Energy efficient lighting system with motion sensors and daylight dimmers. High-performance glazing and building fabric insulation from sustainable sources, locally sourced where possible, as well as use of materials with low embodied carbon. Low water use fittings, including low flow taps and sensoractivated urinal flushing. Building management system controls that activate and deactivate water supply, including hot water, according to occupancy. Appropriate energy management measures via energy metering and BMS. It is predicted that the new building design will have 30% lower absolute CO 2 emissions, compared to the existing building, saving 139 tonnes each year and cutting energy costs. This level of performance is achieved with a combination of a high performance facade with sensible amounts of glass, heat recovery on the air handling systems, generously sized ductwork allowing low specific fan power, and efficient variable refrigerant flow (VRF) air conditioning system with heat recovery.
