  1. 1. PART 2 PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  2. 2. Part L of the UK Building Regulations You are already familiar with some parts of Part L of the Building Regulations, for instance why do central heating systems need to be installed with so many controls and why we need to use (TRV) thermostatic radiator valves Part L of the Building Regulations sets out to increase energy efficiency and reduce our co2 imitations and foot print As of 6 April 2006 split into four sections: L1a New dwellings L1b Existing Dwellings L2c New Buildings other than Dwellings L2d Existing Buildings other than dwellings Fuel &Energy conservation legislation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  3. 3.  ‘Approved Document Part L of the UK Building Regulations requires ‘reasonable provision to be made for the conservation of fuel and power in buildings’. Part L1A sets out minimum energy performance requirements for new dwellings, in the form of limiting fabric U-values and air permeability, efficient building services, effective controls and overall target CO2 emission rates. Part L1B, which has slightly less onerous requirements in many cases, deals with the refurbishment of dwellings. The overall target CO2 emissions and those predicted to be achieved by the dwelling are measured using the Standard Assessment Procedure (SAP)6. These standards are set to rise, leading to increased use of LZC technologies in domestic buildings.’ (CE317, Energy Saving Trust, 2011) Fuel &Energy conservation legislation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  4. 4.   Did you know you could sell some of the energy your home produces back to energy generators via Renewables Obligations Certificates (ROCs).  The government has set out regulations to the major energy producers to generate energy from renewable sources. This means baying it off of people with homes that produce energy through renewable sourses. Use of Renewables PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  5. 5.  The Renewables Obligation is a UK government requirement for licensed electricity suppliers to source a specific and annually increasing percentage of the electricity they supply from renewable sources. The current level is 9.1% for 2008/09, rising to 15.4% by 2015/16. Renewables Obligation Certificates (ROCs) are issued to electricity generators in order to demonstrate that they have reached the required level. Alternatively, these can be purchased on the open market from those who generate renewable energy, or a buyout can be paid.’ (CE317, Energy Saving Trust, 2011) Renewables obligation PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  6. 6.  ‘The Code for Sustainable Homes is the Government’s key strategy vehicle for driving sustainability in the domestic construction sector. It is a credits-based rating system that encompasses many aspects of sustainability, from energy and water through to pollution and the use of materials. There are nine categories in total. Each of the discrete credits is either achieved or withheld and the final score translates into a star rating from one to six.’ (CE317, Energy Saving Trust, 2011) The Code for Sustainable Homes PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  7. 7.  The Act makes it the duty of the Secretary of State to ensure that the net UK carbon account for all six Kyoto greenhouse gases for the year 2050 is at least 80% lower than the 1990 baseline, toward avoiding dangerous climate change. The Act aims to enable the United Kingdom to become a low- carbon economy and gives ministers powers to introduce the measures necessary to achieve a range of greenhouse gas reduction targets. An independent Committee on Climate Change (CCC) has been created under the Act to provide advice to UK Government on these targets and related policies. In the act Secretary of State refers to the Secretary of State PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM The climate change act 2008
  8. 8.  PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM Changes to SEDBUK All boilers must now be SEDBUK 2005 90% or SEDBUK 2009 88% Oil boilers must have an energy efficiency of 85%. There are also now minimum efficiencies for solid fuel boilers and individual heating appliances and requirements for: • Cleansing and water treatment for wet central heating systems • Commissioning certificate to confirm completion • Provision of a suitable set of operating and maintenance instructions • Minimum standards for hot water storage cylinders • Minimum standards for heating and hot water controls • SEDBUK = seasonal efficiency of domestic boilers united kingdom
  9. 9.  Band SEDBUK range A 90% and above B 86% - 90% C 82% - 86% D 78% - 82% E 74% - 78% F 70% - 74% G below 70%PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM SEDBUK TABLE
  10. 10.   The Standard Assessment Procedure (SAP) which is done on a scale from 1 to 100 is the methodology used by the Government to assess and compare the energy and environmental performance of dwellings. Its purpose is to provide accurate and reliable assessments of dwelling energy performances that are needed to underpin energy and environmental policy initiatives.  Energy performance certificates are given (EPC)  All exposed pipework have to be insulated, the building fabric is an insulation too and has a ‘U’ value - the higher the ‘U’ value the better the insulation is The Standard Assessment Procedure (SAP) PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM
  11. 11.  The Central Heating System Specification (CHeSS) was produced by the Building Research Establishment’s BRECSU. CHeSS was seen as essential because of the difficulties facing the domestic heating installation industry due to a lack of common standards and little understanding of what should be done to improve energy efficiency. CHeSS gives recommendations for good practice and best practice for the energy efficiency of domestic wet central heating systems, and plumbers should use them as a basis for developing a system specification and costing's PRACTICE PLUMBING EXAMS © WWW.PRACTICEPLUMBINGEXAMS.COM Central heating System (CHeSS) 2008 CE51
  12. 12.   The 2013 editions of the Domestic and Non-Domestic Building Services Compliance Guides are the current editions for use in England. They support the 2013 editions of Approved Documents L1A and L2A and the 2010 editions of Approved Documents L1B and L2B (as amended).  They provide guidance on complying with Building Regulations requirements for space heating and hot water systems, mechanical ventilation, comfort cooling, fixed internal and external lighting and renewable energy systems.
