44 INDUSTRY VIEWFINDER: BUILDING REGULATIONS (PART F AND PART L) INTRODUCTION How often have you built to these standards before?


THE FUTURE HOMES STANDARD n , the overnment launched its fi rst consultation on strengthening the building regulations, which would pave the way for the uture omes tandard.


uring this process, the consultations discussed realistic meas ures that could be undertaken here to drive down the carbon footprint of homes built after .


uch measures discussed included a range of new ventilation and effi ciency reuirements, as well as proposals to encourage the use of electric technologies such as air source heat pumps or the latest generation of solar panels, as well as the move to phase out certain gas boilers and other fossil fuel heating sys tems in new homes.


s part of the consultation process, it was decided that in order to reach the standards desired by   in which homes are epected to produce  lower carbon emissions com pared to current levels  interim measures would be necessary to ensure the industry is ready for the net stages.


INTERIM CHANGES t the time of writing, these interim measures are now in place, with new developments starting after the th of une  hav ing to produce  lower carbon emissions. Eisting homes are also subect to changes too, with etensions, replacements and


repairs all now reuiring higher standards of energy effi ciency. These reductions in emissions are being achieved through interim uplifts to arts  volumes  and  and  volume  of the building regulations. art  amendments, for instance, introduce new principal performance metrics to measure energy effi ciency. Termed ‘primary energy,’ the metric specifi es the maimum primary energy use for a dwelling  with primary energy described by the E as energy from renewable and nonrenewable sources which has not undergone any conversion of transformation process.


The overnment has also encouraged a fabricfi rst approach here. Though the new values have been criticised by some as ‘unambitious,’ suffi cient insulation and airtightness will be vital to meet the new reuirements, allowing for reduced energy con sumption of the technologies employed to heat and cool spaces. The changes to art  are focussed on ventilation strategies, covering the prevention of indoor air pollution, and a minimum air supply rate of . ls.m.
