CO₂ Savings: Demand Reduction

The results of the simulations show that significant annual carbon savings could be made.  There are two schemes that are looked at to improve the carbon footprint of the project zone.  The first is the best case scenario to see what is the maximum possible saving with improving the makeup of the various dwellings, regardless of cost.  The second scheme will show a more feasible saving that takes into account a more realistic economic allowance for home improvements.  Table 1 highlights the comparison of annual CO₂ savings for the realistic base case for the various dwellings.

	Best Scheme (tonnesCO2 per annum)	Realistic Scheme (tonnesCO2 per annum)
3 Storey Tenement Block	20.24	17.42
4 Storey Tenement Block	25.80	22.28
3 Storey Council Flat	22.38	16.98
4 Storey Council Flat	28.35	21.65
Detached House	6.03	5.07
Semi Detached House	5.568	4.68
Mid Terraced House	4.958	4.25
Total for Project Area	6,705.65	5,197.60

It is important to note that, for both of the schemes; calculations for modern flats were omitted.  This was because the insulation and boiler setups should be already to a high standard due to efficient building regulations that the flats had to meet when they were built.  As well as this, if fabric determinants and boilers could be changed in these modern flats, it would not improve efficiencies by much and the economic implications of these changes far outweigh the benefits gained.
