ENERGY EFFICACY (lumens per watt) DURATION Incasdencent10-17750-2500 h Fluorescent Save 65-75% compared with incasdescent 30-1107000-24000 h High-intensity discharge Save 75-90% compared with incasdescent 25 - 14016000 – 24000 h 10 min to produce light Intense light  industrial use. Low-pressure sodium 25 – 1505000 – 24000 h The most energy-efficient outdoor lighting. Very poor color rendition FLUORESCENT lamps for indoor. LOW-PRESSURE SODIUM lamps for outdoor. LIGHTING MECHANICAL VENTILATION MECHANICAL SUPPLY AND EXHAUST Possibility of preheating and pre-cooling the air supply Possibility of humidify and dehumidify the air supply Optimum comfort in quality air Best noise reduction Best energy saving

10. Recycling Rainwater Plenty rainfall to supply demand Tank sized to hold one months demand. Costs of the tank, filter, pump and installation are: – 2 bed = £2522.70 – 3 bed = £3208.20 – 4 bed = £3893.70

11. ENERGY DEMAND Heating  12 kWh/m 2 year  46035.36 kWh/year  5.3 kW Appliances, lighting, hot water…  90 kWh/m 2 year  345265.2 kWh/year Hot water  Taking 50 l /person day Q= 57294.4 kWh / year = 60-15 ºC Heating + hot water  103329.76 kWh/year  11.8 kW Electricity (appliances, lighting…)  287970.8 kWh/year  32.9 kW CHP 1:2 11.8 kW Heating+ hot water 5.9 kW Electricity 27 kW PV, wind turbines… ASHP 1 :2.4 5.3 kW Heating 2.2 electricity 35.1 kW Electricity PV, wind turbines…

12. Combined Heat and Power CHP sizing: Base load of heat and hot water: 11.8kW. Heat to power ratio : 2:1 The CHP will produce around 5.9kW of electricity. Case study: University of Nottingham 2 DACHS mini-CHP supplied by Baxi Technology UK Each CHP produces 12.5kWth and 5.5kWe
