2. Sustainability and Non Domestic Buildings: Reducing the impactEnergy efficient improvements in commercial buildings Christopher Gorse

3. Identify ways in which commercial buildings can be improved to reduce their impact on the environment.

4.  Natural ventilation • Natural light • Daylight compensation lighting • Effective recycling • Water efficiency measures within the building • Solar shading and control  • Reduced Water Consumption • Low flow taps / showers • Surface water management • Site Waste Management • Use of reclaimed materials

5. Maximise daylight – reducing need for lighting • High air-tightness – reduced thermal loss • Highly insulated – increased u-values throughout • Low carbon heat and power from CHP (combined heat and power) • Using internet protocol to monitor building performance • Feedback systems on energy use • Temperature and humidity • Average building use, annual cycles

6. Free cooling chillers • Heating, cooling and ventilation distributed by active chilled beams • Rainwater harvesting • Grey water – water capture, reuse • Grey water used to flush WC’s and washing machines • Work with water authority to utilise black water • Low water fitting to sanitary areas

7. Green travel plan • Cycling storage • Showers to encourage alternative means to get to the place of work • Re-use of brown field land • Natural grasses and plants introduced • Dedicated Energy Efficient Lighting, PIR’s (passive infrared • sensors)

8. Material Sourcing • Recycling Facilities • Photovoltaics • Wind power – local wind turbines, large scale turbines that feed into the grid • Hydropower • Rooftop wind turbines to communal electricity supply or Large scale wind turbine • Rooftop solar thermal system - hot water • Heat Recovery mechanisms - Heating/Cooling & Hot Water system

9. Reducing need to travel • On site amenities • Cycle storage • Carbon Footprinting • Health & Wellbeing on site • Ecological assessment of site • A/A+ Rated Appliances • On Site Renewable Energy • Heating/Cooling via Open Loop Borehole & VRF (variable refrigerant flow)
