They are primarily focused on new non-domestic buildings but also include policies for existing non-domestic buildings and new and existing housing.<\/p>\n<p>Why are they changing? The Department for Levelling Up, Housing &amp; Communities says the changes \u2018mark an important step on our journey towards a cleaner, greener built environment and it supports us in our target to reduce the UK\u2019s carbon emissions to net-zero by 2050\u2019.<\/p>\n<p>The bulk of the changes are part of the roadmap, or rather interim measures to the government&#8217;s Future Homes Standard and Future Buildings Standard \u2013 planned for 2025 \u2013 for which a key part is that all new builds are capable of being net zero in terms of operational carbon when the grid decarbonises.<\/p>\n<p>According to numbers from the Department for Business, Energy &amp; Industrial Strategy, heating and power account for 40 per cent of the UK\u2019s total energy use. So implementing new building regulations that reduce the need to heat and power buildings can help the UK make lengths to reach its zero carbon goals.<\/p>\n<p>But will they enforce greener projects? And how will they improve on current Building Regulations? Architects and engineers criticised the government&#8217;s amendments to energy efficiency regulations in December when the AJ first reported on the proposed changes, describing them as <a href=\"https:\/\/www.architectsjournal.co.uk\/news\/architects-slam-extremely-disappointing-changes-to-energy-efficiency-regs\">\u2018a tiny step at a time when we need to be making a huge leap\u2019<\/a>.<\/p>\n<h3>What are the key changes?<\/h3>\n<ul>\n<li>From 15 June, new-build homes will need to produce at least 31 per cent less carbon emissions. The installation of electric heating systems combined with renewable energy sources such as solar are both seen as enablers for doing so<\/li>\n<li>New non-domestic builds will need to produce at least 27 per cent less carbon emissions with similar low energy measures to the previous in place<\/li>\n<li>A new metric for measuring energy efficiency has been introduced. \u2018Primary energy\u2019 will be used to measure the efficiency of a building\u2019s heating as well as the energy required to deliver fuel to a building (this even extends to including the efficiency of the power station supplying the electricity)<\/li>\n<li>New minimum efficiency standards have been provided. In all new domestic builds, the new U-value for walls will be 0.18 W\/m<sup>2<\/sup>, 1.4 for windows and rooflights and 1.4 for doors. In non-domestic builds there\u2019s a lowered U-value of 0.26 for walls and majority of windows\/curtain walling must achieve 1.6 W\/m<sup>2<\/sup><\/li>\n<li>New and replacement heating systems in both domestic and non-domestic builds must have a maximum flow temperature of 55\u00b0C<\/li>\n<li>Existing non-domestic buildings must improve the efficiency of heating and hot water boiler systems through installation of new controls. In new buildings (non-domestic), the minimum lighting efficacy has been raised to 80 luminaire lumens per circuit watt for display lighting and 95 for general lighting<\/li>\n<li>Background trickle vents have been recommended for non-domestic buildings along with a new requirement for CO2 monitors in all offices. The recommended minimum air supply rate is 0.5 l\/s.m<sup>2<\/sup><\/li>\n<li>The Fabric Energy Efficiency Standard (FEES) level in new homes will be set by a \u2018full fabric specification\u2019 and SAP compliance will now be applied to extensions built on existing properties<\/li>\n<li>The new Approved Document O introduces glazing limits in new-build homes, care homes, schools and student accommodation to reduce unwanted solar gain. It also enforces new levels of cross-ventilation<\/li>\n<li>The new Approved Document S requires all domestic new builds to have the preparatory work completed for future installation of an electric vehicle charging point<\/li>\n<\/ul>\n<p>The interim measures will apply to all projects after 15 June 2022, except where a building notice has been given or full plans have been submitted with local councils. However, the new regulations will apply to all projects regardless from 15 June 2023.<\/p>\n<p><em>The changes are outlined in documentation <a href=\"https:\/\/assets.publishing.service.gov.uk\/government\/uploads\/system\/uploads\/attachment_data\/file\/1057367\/Circular_letter_Jan_2022.pdf\">here<\/a>.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The updated regulations include amendments to Approved Documents Part F (Ventilation) and Part L (Conservation of fuel and power) and the release of a new Approved Document for Overheating (Part O)\u00a0and Infrastructure for charging electric vehicles (Part S).
