Changes that pay for themselves within 3 years
Recommendation Potential impact
Replace tungsten GLS lamps with CFLs: Payback period dependent on hours of use. Low
Consider replacing T8 lamps with retrofit T5 conversion kit. High
Introduce HF (high frequency) ballasts for fluorescent tubes: Reduced number of fittings required. Low
In some spaces, the solar gain limit defined in the NCM is exceeded, which might cause overheating. Consider solar control measures such as the application of reflective coating or shading devices to windows. Medium
Changes that pay for themselves within 3 to 7 years
Recommendation Potential impact
Add optimum start/stop to the heating system. Low
Changes that pay for themselves in more than 7 years
Recommendation Potential impact
The default heat generator efficiency is chosen. It is recommended that the heat generator system be investigated to gain an understanding of its efficiency and possible improvements. Low
Some walls have uninsulated cavities - introduce cavity wall insulation. Low
Some windows have high U-values - consider installing secondary glazing. Low
Add weather compensation controls to heating system. Low
Some solid walls are poorly insulated - introduce or improve internal wall insulation. Low
