Cavity Wall and Loft Insulation: Cavity wall insulation and loft insulation reduce heat loss from the building,
while reducing the amount of fuel you need to keep warm. Draft Proofing: Draft proofing around external doors
and windows reduces losses of heat from the building. Double Glazed Windows: Double glazed windows trap a layer of
air between the two panes, creating an insulator that reduces heat losses. Energy Efficient Light Bulbs: Energy efficient light
bulbs can produce the same amount of light with 80% less energy input than
conventional tungsten bulbs. Condensing Boiler: Condensing boilers are applicable for
houses with water based heating systems. They extract an additional 10 to 20%
of the heat from flue gases compared to conventional boilers. Ground Source Heat Pump: Ground source heat pumps are under-floor
heating systems that can be used to replace traditional boilers that are used
for heating. Ground source heat pumps use temperature differences between the
ground adjacent to the building and the air inside to help warm the building
in winter and cool it in summer. A Tonne of Carbon: One tonne of CO2 emissions occupies 556m3 of space at 25 degrees Celsius and standard pressure. The volume of water in an Olympic swimming pool is approximately 2500m3. Therefore the average household CO2 emissions in the UK (approximately 10 tones per year) would be enough to fill about 2 Olympic swimming pools and the average household emissions in the USA (approximately 20 tonnes per year) would be enough to fill about 4 and a half Olympic swimming pools |
