Implementation Part 4, Energy Performance of Buildings (Certificates and Inspections) (England & Wales) Regulations 2007 implements Article 9 of the Energy Performance of Buildings Directive, requiring: Ø Local weights and measures authorities are responsible for ensuring that owners of air-conditioning (AC) systems over 12 k. W are in possession of an inspection report. Ø Systems have to be inspected by an accredited inspector at least once every 5 years. (Sites which have had EPCs and DECs done can be revisited and have an Air Conditioning Inspection performed. ) Stroma Certification – ABBE Level 3 Air Conditioning course material 2015 House keeping © Stroma Certification 2014 | Version 1. 0

Implementation Why are Air-Conditioning Inspections Required? Inspections designed to: - üImprove efficiency üReduce electricity consumption üReduce operating costs üReduce carbon emissions Will highlight opportunities for: - q. Improvements to operation q. Replacement of older less efficient systems q. Replacement of oversized systems Stroma Certification – ABBE Level 3 Air Conditioning course material 2015 House keeping © Stroma Certification 2014 | Version 1. 0

Implementation Responsible Ownership of Systems: - ØBuilding owners/managers who control air conditioning systems have statutory obligations and duties of care in the operation and maintenance of air conditioning systems. ØAir-conditioning energy inspections are additional to the normal activities associated with the operation and ownership of the air-conditioning systems. Stroma Certification – ABBE Level 3 Air Conditioning course material 2015 House keeping © Stroma Certification 2014 | Version 1. 0

Implementation Definition of a building: Ø “a roofed construction having walls, for which energy is used to condition the indoor climate, and a reference to a building includes a reference to a part of a building which has been designed or altered to be used separately”. A part of a building designed or altered to be used separately: – – where accommodation is adapted to for separate occupation; could be indicated by having separate access; separate provision of heating, ventilation and air-conditioning (HVAC); shared HVAC but the occupier has the ability to independently control the services • (for example shared kitchen and toilet facilities. ) Stroma Certification – ABBE Level 3 Air Conditioning course material 2015 House keeping © Stroma Certification 2014 | Version 1. 0

Implementation How is an Air-Conditioning System Defined? Air-Conditioning System: Ø “refers to any system where refrigeration is used to provide cooling for the comfort of the occupants”. It Excludes: – separate refrigeration provided solely for process application • e. g. cold store, pharmaceutical production, server rooms etc. Stroma Certification – ABBE Level 3 Air Conditioning course material 2015 House keeping © Stroma Certification 2014 | Version 1. 0

Display Energy Certificate (DEC) – required by occupiers of public buildings; • building greater than 1, 000 m 2; • occupied by public Authority or institututions providing public services to a large number of persons; • the public visit the building. • New regualtion that came in on 1 st January 2013, buildings greater than 500 m² but are valid for 10 years • Now the building level is >250 m²and are valid for 10 years Stroma Certification – ABBE Level 3 Air Conditioning course material 2015 House keeping © Stroma Certification 2014 | Version 1. 0

Implementation Article ‘ 3’ of the F-Gas Regulation requires: - – operators to use all technically feasible measures; – not entailing disproportionate cost; • to prevent leakage of F-Gas to the atmosphere • and to repair any detected leakage from: – refrigeration, air conditioning and heat pump equipment and associated circuits; – fire protection systems. • “Checked for leakage” means that: – Equipment or system parts that are most likely to leak have been examined using direct or indirect methods.
