Decreased CO² Emissions with InfraMax LX70 HC Energy Efficient Coating Installed
HELP TO REDUCE THE 'CARBON FOOTPRINT' EVEN FURTHER!
POSSIBLE SAVINGS
From recent research carried out in the US:
Accepted CO² emissions from power plants to produce electricity are as follows:
Natural Gas Burning Plants…………………………..…...1.0 lbs. per 1 kWh
Oil Burning Plants…………………………………...……...1.7 lbs. per 1 kWh
Coal Burning Plants……………………………………..….2.0 lbs. per 1 kWh
(Source: Sustainable Energy and Economy Network)
Typical large office building in London with 24,000 square feet of glass (Clear IGU) would require 89,971 less kWh with the application of InfraMax® LX 70 window film. This would be a reduction of the following CO² emissions depending on the type of power plant:
Natural Gas Burning Plant……………………….…….…89,971 lbs. per year
Oil Burning Plant…………………………………………152,950 lbs. per year
Coal Burning Plant……………………………………….179,942 lbs. per year
(Source: Demand Analyzer Program - Based on DOE 2)
Based on the above, a square foot of applied InfraMax LX 70 with a shading coefficient of .53 would reduce CO² emissions as follows for the different types of power plants:
Natural Gas Burning Plants………………..…………….3.75 lbs. per year
Oil Burning Plants……………………………………..…..6.37 lbs. per year
Coal Burning Plants…………………………………..…..7.50 lbs. per year
The building used in this example is a new building (post 1992) with a chiller system with COP of 4.5 - this is a very efficient system and probably exceeds the efficiency of older and smaller buildings. With an air conditioning system, with an SEER of 12 (100% efficiency) the usage rate is approximately 1kWh per ton of cooling (Source: Pacific Gas and Electric Co.) and that figure was used in these calculations.
Relating this to a particular case study being carried out, with information provided of window sizes and floor plans of a large city office building, it has been calculated that the projected reduction in CO2 emission would be as follows:
Natural Gas Burning Plants………………………….....292.81 Tons per year
Oil Burning Plants………………………….……….…...497.77 Tons per year
Coal Burning Plants………………………………..…….585.62 Tons per year
