INDUSTRY VIEWFINDER: BUILDING REGULATIONS (PART F AND PART L) 43 RESPONDING TO


CHANGE – THE IMPACTS OF THE AMENDED PARTS L AND F


EXECUTIVE SUMMARY W


ith over one in fi ve homes in the country being fi rst constructed over  years ago, the  has the oldest  and arguably most ineffi cient  housing stock


in Europe.


n no small part because of this, at present it is estimated that over  of the ’s carbon emissions are produced by the housing sector, and, with etreme heat events already becoming more freuent and severe, it is clear that the overnment, and the sector itself, needs to do more. hile such action on retrofi t at present appears woefully inadeuate  with the reen omes rant argued to be but a fl ash in the pan by many  when it comes to new houses and new additions at least, the epartment for evellingp, ousing and ommunities  is moving forwards. s part of the overnment’s commitments to achieving et ero by , in a maor step for the construction industry  involving a number of consultations and revisements  The uture uildings tandard now reuires that new homes in England must produce around  less carbon emissions compared to the old regulations, as an interim measure towards  less by .


chieving this through changes to arts  of the uilding


egulations  with updates to art  upgrading the ventilation reuirements to support these tighter, more effi cient homes  this is an important move towards supporting the many proven technologies available today that can vastly reduce the emissions of a home.


hether it’s reducing energy consumption through insulation, subsidising energy use through solar panels, or heating a home with lowcarbon alternatives, the conservation of power and heat, and the ventilation to match, has never been easier, or more effective.


n our research of  housebuilders and developers   at director or euivalent level, and the vast maority being smaller fi rms building under  homes a year   our respondents cited a wide range of benefi ts they epect from the new changes and the epansion of these technologies, from the contribution these moves will make towards the ’s ourney to et ero, to reducing fuel poverty and closing the performance gap.


f course despite these lofty aims, innovation often comes at a cost in time, skills and fi nance, and many housebuilders  or perhaps more importantly, homebuyers  do not believe they can glean the value necessary to ustify the investment.


hile it is hoped by some that the changes to art  and  introduced will ‘level the playing fi eld’ for eco conscious builders, many housebuilders are especially fearful of rising costs  not least smaller fi rms. y far the most common concern among our respondents,  believe increased construction costs are the biggest challenge to the adoption of the standard, on average epecting building costs to rise by an average of k per unit  with the maority  set to pass these costs onto the consumer.


eyond this, many of our respondents were also fearful of the array of other challenges the standards pose, largely focussed on a lack of skills, eperience and homeowner awareness. n this research, ousebuilder  eveloper intends to delve deeper into how our respondents are adapting to these changes, how well the changes are understood, and the wider impacts they epect the regulations to have on their businesses  including more detailed, ualitative commentary from housebuilders pringbourne omes, tonewood artnerships and ayfi eld omes.
