The recent Stern report on the economic cost of Global Warming again emphasises the need to take action now on reducing the nation’s carbon footprint.

As Climate change continues to rise up the political agenda, reports last month indicate that the Government is likely to propose further legislation for the next session of Parliament. This all points in one direction; we can expect ever-tighter constraints on emissions of CO2 .
Transport, power generation, industry and households all have their part to play in the reduction of greenhouse gas emissions, but with C02 making up 88% of the cocktail, the reduction of energy waste in the home and at work is where we can act as individuals.
On the new home front, with public awareness growing of the need to reduce greenhouse emissions, smart builders are focussing on achieving the highest SAP rating possible for their new dwellings. Displaying the SAP rating to potential buyers is mandatory and with 45% of CO2 emissions coming from buildings and 40% of the emission savings expected to be derived from the domestic residential sector, building regulations part L 1 and F1 have been revised to improve energy efficiencies.
Ventilation is now linked to energy efficiency. The new SAP appendix Q procedure promotes carbon efficiency through new technologies, which can be factored into the SAP rating.
With regard to energy efficient mechanical ventilation, the new Part L SAP calculations require Specific Fan Power and heat exchanger efficiency as independently tested through Appendix Q.
