There is much talk recently about the high temperatures in the UK. Should we aircondition our buildings ?				The cost to insulate a typical classroom, 9m x 10m. Wall area 95 m2 Ceiling area 90 m2 Total area 185 m2 Plasterboard + 80mm Expanded Polystyrene back. 20/m2 Installation 10/m2 Plastering cost 20/m2 Painting 10/m2 Floor area 90 m2 20 mm extruded polystyrene 8/m2 Laminate flooring 24/m2 500mm fan installed 800 Total				Totals 3,700 1,850 3,700 1,850 720 2,160 800 14,780
NO. It takes ZERO CO2 to cool them (well almost) See how. We provide costing >>
*Insulation is cost effective, and the only way to reduce CO2 pollution.*
We simply either open the windows during the night or install fans timed to come on when it is cool at night. The graph for Sheffield below shows the temperatures during the heatwave were always below 20 degrees overnight (except for one day at under 21 degrees). In order to maintain the comfortable temperatures during the day, the rooms must be insulated. We provide costing to insulate a typical classroom, 9 metres x 10 metres.
					5 kWh airconditioner 8,000 Running cost 5*0.25 = 1.25/hr For a day, hours 10 Number days / year say 120 Annual cost = 1,500 The insulation is cheaper after only 5 years. And of couse vastly reduced CO2 footprint.
