A planning written ministerial statement was also published which outlined the government’s policy on the application of these technical standards for plan making and decision-taking. Please tell us what format you need. It will help us if you say what assistive technology you use.This addendum brings the Code into line with regulatory and national guidance changes.) It sets out the process by which a Code assessment is reached. It aims to make gaining a Code assessment as simple, transparent and rigorous as possible. A summary of the main changes made to the Code are provided in The Code for sustainable homes: Summary of the changes to the Technical Guidance - 2010 publication. To aid clarity, it follows the format of the Technical Guidance and is split into separate sections.

It was launched in 2006 to help reduce UK carbon emissions and create more sustainable homes. It was part of a package of measures including; Building A Greener Future and Planning Policy Statement: Planning and Climate Change. Its implementation is managed by BRE Global.Sellers were required to issue buyers of newly constructed homes a sustainability certificate (either a Code for Sustainable Homes certificate or a nil-rated certificate ). However, in 2010 the requirement for Home Information Packs was suspended along with the requirement for a sustainability certificate.http://xn--76--pdd4bl.xn--p1ai/pic/userfile/de-1000-fhd-centrifuge-manual.xml

It measures sustainability against nine categories:Credits are awarded depending on the performance of the dwelling in each area, and weightings are then applied to adjust their relative values.However, the Code as a Government standard, hasn’t resonated with consumers as this is key to really driving the market further forward. BRE is now working with the industry to do this.'It also allows house builders to highlight the innovative features of their homes and differentiate themselves in the marketplace. Amongst a great number of wide-ranging changes, the report states, 'The government does not intend to proceed with the zero carbon Allowable Solutions carbon offsetting scheme, or the proposed 2016 increase in on-site energy efficiency standards, but will keep energy efficiency standards under review, recognising that existing measures to increase energy efficiency of new buildings should be allowed time to become established.'November 2013.

The Code was an environmental assessment method intended to measure the whole home by taking into account nine impact categories.http://everestart.com/images/stories/de-809tc-manual.xml It was used by local planning authorities to set standards for new housing, and was mandatory for houses built using public sector funding. Private sector builds were required to be rated against the Code so that homeowners knew whether their home was built to higher standards than the Building Regulations. Since March 2015, the Code has been withdrawn apart from in legacy cases. The Code still operates for housing development supported by the Welsh Assembly and its Sponsored Bodies. In Practice Use of the Code for Sustainable Homes The Government withdrew the Code for Sustainable Homes on 27 March 2015 in a written ministerial statement following a review of housing standards. The code was withdrawn for all cases in England apart from the management of legacy cases. Legacy cases are classed as: those where residential developments are legally contracted to apply a code policy (eg affordable housing funded through the National Affordable Housing Programme 2015 to 2018, or earlier programme) where planning permission has been granted subject to a condition stipulating discharge of a code level, and developers are not appealing the condition nor seeking to have it removed or varied. Planning consents can no longer require compliance with the Code for Sustainable Homes. Instead, local authorities can set higher standards than the Building Regulations for access and water where they can demonstrate a local need for higher standards. There is also the option to adopt a nationally described space standard and security requirements have been included in the Building Regulations through the introduction of Part Q. In terms of energy efficiency, the Government has advised that local authorities are able to set energy efficiency standards higher than the Building Regulations using powers under the Planning and Energy Act 2008. This view was clarified in the Government’s response to a consultation on the revised National Planning Policy Framework (NPPF) in 2018.http://www.familyreunionapp.com/family/events/boss-dr-110-service-manual Although these additional options will give local authorities some choice to require developers to build standards above the minimum requirements, many issues covered by the Code are no longer included within the building standards. Categories lost include materials and life cycle, pollution and ecology. Zero carbon homes In its report, Fixing the Foundations: Creating a More Prosperous Nation, the Government has also stated that it does not intend to proceed with its zero carbon homes policy which required all new homes to meet a zero carbon standard by 2016. Wales The Code still applies in Wales for all new housing supported by the Welsh Government. In such cases, it should be read in conjunction with supplementary technical guidance and addendums to the Code. These amendments bring the Code in line with national guidance and regulatory changes, particularly in relation to Part L of the Building Regulations and surface water run-off and flooding. Overview of the Code for Sustainable Homes The Code measures the sustainability of a new home against nine categories of sustainable design, rating the “whole home” as a complete package. Each of the categories has an impact on the environment for which mitigation measures to reduce their impact can be objectively assessed, evaluated and delivered in a practical and cost-effective way. Assessment Procedures Assessment is carried out by specifically trained and accredited independent assessors. For legacy cases, the client for the assessment chooses a service provider (currently BRE Global Ltd and Stroma Accreditation Ltd). The service provider then offers a register of licensed and trained assessors for the client to choose from. The chosen Code assessor registers the development formally with the service provider and will then conduct initial design stage checks, recommend a sustainability rating and issue an interim code certificate based on design drawings, specifications and commitments.http://phdpezeshki.com/images/804hv-manual.pdf A post-construction stage completion check will verify the rating before a final code certificate of compliance is issued. Reporting Quarterly statistical updates were provided by the Department for Communities and Local Government (DCLG, now the Ministry of Housing, Communities and Local Government) until the withdrawal of the Code in March 2015. The DCLG reported that there were 197,851 post-construction stage certificates and 297,375 design stage certificates issued up to 31 December 2014. Guidance The Code takes account of nine categories as defined in the publication Code for Sustainable Homes: Technical Guide. As a result of the Housing Standards Review many of the requirements of the Code for Sustainable Homes were consolidated into the Building Regulations. Prior to the withdrawal of the Code an addendum was published in May 2014 bringing the Code in line with regulatory and national guidance changes and to Part L of the Building Regulations. Part 1 of the guidance includes explanations of the: procedure for the assessment of houses and credit verification scoring and weighting system. Part 2 includes: the environmental issues to be assessed performance requirements and their evaluation evidence required to confirm performance evaluation calculation algorithms, checklists and other tools that are part of the assessment method. The Code in Practice A star rating system is used with a blue star awarded for each level achieved, extending from one star to six (the maximum), depending on the extent to which the building has achieved the required Code standards. In order to achieve a particular Code level, and the associated sustainability rating, a home must integrate minimum standards, and attain additional points for other design features. The following are the environmental categories and issues (“M” designates mandatory aspects of the Code). Energy and CO 2 emissions: dwelling emission rate (M) fabric energy efficiency (M) energy display devices drying space energy labelled white goods external lighting low and zero carbon technologies cycle storage home office. Water: indoor water use (M) external water use. Materials: environmental impact of materials (M) responsible sourcing of materials (basic building elements) responsible sourcing of materials (finishing elements). Surface water runoff: management of surface water runoff from developments (M) flood risk. Waste: storage of non-recyclable waste and recyclable household waste (M) construction site waste management composting. Pollution: global warming potential of insulants NOx emissions. Health and wellbeing: daylighting sound insulation private space lifetime homes (M). Management: home user guide considerate constructors scheme construction site impacts o security. Ecology: ecological value of site ecological enhancement protection of ecological features change in ecological value of site building footprint. The Code assigns one or more performance requirements (assessment criteria) to all of the environmental issues. When each performance requirement is achieved, a credit is awarded. The total number of credits available to a category is the sum of credits available for all the issues within it. Total Credits Available, Weighting Factors and Points Category Total credits Weighting factor () Approximate weighting value of credit Energy and CO 2 emissions 31 36.4 1.17 Water 6 9.0 1.50 Materials 24 7.2 0.30 Surface water run-off 4 2.2 0.55 Waste 8 6.4 0.80 Pollution 4 2.8 0.70 Health and wellbeing 12 14.0 1.17 Management 9 10.0 1.11 Ecology 9 12.0 1.33 Total — 100 — Within each category, credits are awarded for achieving specified degrees of performance. The weighting factors show the contribution made by each category to the total performance recognised and rewarded by the Code. Mandatory minimum standards Three uncredited mandatory issues are: environmental impact of materials management of surface water runoff from developments storage of non-recyclable waste and recyclable household waste. If any of the standards for the three non-creditable issues are not met, then a zero rating will result regardless of the other credits achieved, including the creditable mandatory issues. Two issues which had been increasing in importance, and had increasing mandatory minimum standards were: dwelling emission rate indoor water use. Note: A definition of a zero carbon home was omitted from the 2014 addendum to the Code as it will be defined by future legislation. The final two issues with mandatory requirements are fabric energy efficiency (FEE) and lifetime homes. To achieve an overall Code rating of level 5 it is necessary to achieve at least seven credits in FEE. To achieve an overall Code rating of level 6 it is necessary to achieve at least seven credits in FEE and three credits in lifetime homes. If all the non-creditable mandatory standards are met, but one of the creditable mandatory issues fails to reach the minimum required to achieve a higher level, the rating will be determined by the lowest mandatory level met. The assessment process (now for legacy cases only) should progress in order through the environmental impact categories and issues. Check that the non-creditable mandatory issues have been met. The mandatory requirements for CO 2 emissions, FEE, internal water use and lifetime homes should be checked and confirmed at the minimum values to meet the Code level sought. The remaining tradable credits should be checked and confirmed that they contribute to the required Code level. Further credits are available on a free-choice or tradable basis from other issues so developers may choose how to add performance credits (converted through weighting to percentage points) to achieve the rating they are aiming for. The Directive requires that all new homes (and other homes, when they are sold or leased) have an Energy Performance Certificate providing key information about the energy efficiency and carbon performance of the home. To avoid the need for duplication, energy assessment under the Code uses the same calculation methodology. Practical Examples In 2006, the DCLG issued details of how some of the levels will be calculated. The examples below to detail the two extremes of levels under the Code for Sustainable Homes: Levels 1 and 6. Although the Code was subsequently updated and has now been withdrawn, the examples are useful in demonstrating how consideration of the various environmental issues can lead to the achievement of a particular Code level. Code Level 1 To be graded Level 1, a home would have to be 10 more energy efficient than one built to the standards of the Building Regulations 2006. This could be achieved by: improving the thermal efficiency of the walls, windows, and roof (eg by using more insulation or better glass) reducing air permeability by improving the control of the fresh air into a home, and the stale air out of a home — a certain amount of air ventilation is needed in a home for health reasons installing a high efficiency condensing boiler designing the fabric of the home to reduce thermal bridging (thermal bridging allows heat to easily escape between the inner walls and the outer walls of a home). The home would have to be designed to use no more than about 120 litres of water per person per day. However, this still does not complete the list of requirements. To be awarded Level 1, the home must amass a total of 36 points. Code Level 6 At the other extreme, a home meeting the exemplary Level 6 status will have to be completely zero carbon with zero net emissions of CO 2 from all energy use in the home. This could be achieved by: improving the thermal efficiency of the walls, windows and roof as far as is practically possible reducing air permeability to the minimum consistent with health requirements installing a high efficiency condensing boiler, or being on a district heating system carefully designing the fabric of the home to reduce thermal bridging using low and zero carbon technologies such as solar thermal panels, biomass boilers, wind turbines, and combined heat and power systems (CHP) (this would mean that energy taken from the national grid would have to be replaced by low or zero carbon generated energy, so that over a year, the net emissions would be zero). Furthermore, the home will have to be designed to use no more than about 80 litres of water per person per day. To achieve the standard would also mean that about 30 of the water requirement of the home was provided from non-potable sources such as rainwater harvesting systems or grey water recycling systems. Other minimum requirements are required for: surface water management materials waste management. In fact, they would need to address 90 of everything in the Code to achieve Level 6, including: energy efficient appliances and lighting supplying accessible water butts reducing surface water run-off as much as possible using highly environmentally-friendly materials minimising construction waste maximum, accessible provision for recycling improved daylighting, sound insulation and security building to the Lifetime Homes standard assessing and minimising the ecological impact of the construction of the home. Case studies Four volumes of case studies were issued by the DCLG, providing examples of how new Code Homes were designed, planned and built, and what they are like to live in. In February 2014, the Zero Carbon Hub published a guide that uses a number of new housing developments as illustrative schemes to demonstrate approaches that could be taken. Zero Carbon Strategies for Tomorrow’s New Homes gives specification details for three approaches categorised as: balanced, extreme fabric, or extreme low carbon technologies. It should be noted that the Zero Carbon Hub is no longer being actively contributed to or updated, but information on improving the performance of new homes is still accessible on its website. EcoHomes The Code for Sustainable Homes was developed using the Building Research Establishment’s (BRE) EcoHomes System, which was itself intended to reduce the impact of affordable housing projects, in particular within the social housing sector. Since the withdrawal of the Code for Sustainable Homes, BRE has developed a voluntary standard, the Home Quality Mark (HQM), that is designed to provide an indication of the quality and performance of a new home allowing house builders to differentiate themselves in the marketplace. Using a five-star rating system, the HQM provides clear information to householders on the overall running costs of the home, its health and wellbeing benefits, the environmental footprint of the home as well as its resilience to flooding and overheating to allow for changes in climate. The HQM is now open for registrations in England, Scotland and Wales through a licensed HQM assessor. Assessors can be found on the online Green Book.A Guide for Building Designers, Operators and Users (2010) Specification Specification Code of Practice External Environment.
