Carbon Dioxide (CO2) Equivalents (1990)
 
CO2 emissions are often expressed in terms of their carbon content. One tonne of carbon is equivalent to 3.67 tonnes of carbon dioxide. Electricity consumption produces more carbon dioxide than other fuels. This is produced from the amount of fuel burnt at the power stations to generate electricity.
 
Fuel Kg co2/Kwh Kg Carbon/Kwh
Coal 0.31 0.085
Coke 0.44 0.12
Other Solid Fuel 0.48 0.13
Gas 0.21 0.057
Oil 0.30 0.057
Electricity 0.73 0.20

'U' Values
Here are some typical 'U' Values as guidance in comparing structures and structural options.

steel or asbestos roofing sheets, unlined 6.0 (very poor) The rate at which buildings let heat escape is measured
single glazing windows 5.7 by a figure called the 'U' value, in
flat roof, felt on metal, no ceiling 3.3 Watts/sq metre/°C. This means that thin walls
double glazing sealed window units 2.9 have higher 'U' values indicating more heat loss.
cavity brick wall. 11", plastered 1.6 Good insulation produces lower 'U' values.
flat roof, felt on metal, plasterboard 1.5  
cavity loss density block wall, plastered 1.1 There are British Standards for the design of
tiled pitched roof, felt underlay 0.8 new buildings, which in general should have an
cavity wall with foam filling 0.5 average 'U' value of better than 0.45 (1990
fully insulated roof 0.4 (good) Building Regulations
