23 Energy Performance of Buildings Directive
Climate Change Climate change now seen to be “unequivocally” happening CO2 levels highest ever recorded This rapid change in CO2 levels has been linked to human activity It is predicted we have between 10/15 years left to implement serious measures to reduce emissions British Government has made a pledge to reduce Carbon emissions by 60% by 2050

24 Energy Performance of Buildings Directive
Kyoto protocol; The Kyoto Protocol is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC or FCCC) It set binding obligations on the industrialised countries to reduce their emissions of greenhouse gases. The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February 2005. The Kyoto Protocol is seen as an important first step towards a truly global emission reduction regime that will stabilize GHG emissions

25 Energy Performance of Buildings Directive
The UK has passed legislation that introduces the world’s first long-term legally binding framework to tackle the dangers of climate change. The Climate Change Act created a new approach to managing and responding to climate change in the UK, by: setting ambitious, legally binding targets taking powers to help meet those targets strengthening the institutional framework enhancing the UK’s ability to adapt to the impact of climate change establishing clear and regular accountability to the UK Parliament and to the devolved legislatures

26 Energy Performance of Buildings Directive
A key part of this legislation is the Energy Performance of Buildings Directive first published in 2002, It requires all EU countries to enhance their building regulations and to introduce energy certification schemes for buildings. All countries were also required to have inspections of boilers and air-conditioners. The EPBD was implemented in the UK in 2007

27 Energy Performance of Buildings Directive
Article 7 of the Energy Performance of Buildings Directive states: An energy performance certificate must be produced when a building is constructed, sold or rented out. These EPCs can only be produced by qualified and/or accredited energy assessors working in an independent manner. Display Energy Certificates EPBD Energy Performance Certificates The EPBD is very long and wordy, the bit which relates to us is…..

28 Energy Performance of Buildings Directive
Energy Labels First we had Washing Machines Then we had cars Now we have buildings Introduced through EU Directive 2002

33 EPCs for Non-domestic Properties
EPC for Non-Domestic Building?

34 Energy Performance of Buildings Directive
WHAT The EPC legislation was introduced in September 2007 Initially EPCs formed part of the Home Information Pack or HIP The HIP was abolished in 2010 by the coalition Government, but the EPC is still required for any property which is being sold or rented. The regulations apply to England, Wales, Northern Ireland and Scotland

35 Energy Performance of Buildings Directive
All Energy Performance Certificates (EPC’s) contain Energy Efficiency Rating and Environmental Impact Rating Current and potential costing for heating, lighting and hot water Summary of the property’s energy performance related features Recommendations to improve the energy efficiency of the property, with explanations.

36 Energy Performance of Buildings Directive
Domestic Energy Performance Certificate Calculated using RdSAP (Reduced Data Standard Assessment Procedure) Normalised for occupancy and weather Valid for up to 10 years Green Deal measures are valid for 3 years The owner of the property is not obliged to implement any of the recommendations

37 Energy Performance of Buildings Directive
Energy Assessors Only accredited energy assessors are able to carry out assessments and produce EPC’s and DEC’s To be accredited you must: hold the relevant qualification for the buildings you wish to survey, e.g. DEA, NDEA L3, 4 or 5 For DEA you must have a recent CRB check Join a Government approved accreditation scheme, such as Stroma

38 Energy Performance of Buildings Directive
Levels of EPC Assessors Domestic Energy Assessors use RdSAP Level 3 – for simple commercial buildings using SBEM Level 4 – more complex commercial buildings (new and existing) using SBEM Level 5 – highly qualified consultants able to survey complex buildings using Dynamic Simulation Models

39 Energy Performance of Buildings Directive
Buildings Requiring DEC’s Schools (not private) Leisure Centres (not private clubs) Hospitals (not private unless NHS patients are admitted) Public Golf Clubhouses Libraries Museums and Art Galleries operated or sponsored by Local Authorities

40 Energy Performance of Buildings Directive
Exempt from EPCs/DECs Temporary buildings in use for < 2 years (e.g. Site Offices) Places of Worship Low energy demand buildings (e.g. Barns) Stand-alone buildings < 50m2 (Sheds, Summer Houses) Listed buildings(sale & rental)

41 Differences between SAP and RdSAP
Used for new dwellings. Used for buildings which have undergone a ‘change of use’. Report produced off plan. Property is not visited. Uses a more comprehensive methodology. Assessor must hold Dip OCDEA qualification. Report based on U-values. Uses SAP software. RdSAP Used for existing dwellings. Assessment conducted at the dwelling. Uses a reduced methodology taken from SAP. Assessor must hold DipDEA qualification. Report based on assumptions. Uses RdSAP Software. The following points relate to SAP: Used for new dwellings Used for buildings which have undergone a ‘change of use’ Report produced off plan. Property is not visited Uses a more comprehensive methodology Assessor must hold Dip OCDEA qualification Report based on U-values Uses SAP software RdSAP relates to the following: Used for existing dwellings Assessment conducted at the dwelling Uses a reduced methodology taken from SAP Assessor must hold DipDEA qualification Report based on assumptions Uses RdSAP Software

42 RdSAP RSAP stands for Reduced data Standard Assessment Procedure.
RdSAP is the Government approved calculation used to calculate the ratings on an EPC. RdSAP is derived from full SAP, Standard Assessment Procedure, which is used for assessing newly built dwellings. We are currently using RSAP version 9.91, updated on 1st April 2012. RdSAP 9.91 includes a few additional options which had not been available previously and make RSAP more flexible. RdSAP determines what data should be gathered during an assessment and how it should be entered into the software to produce the EPC. All Accreditation Schemes provide access to approved RdSAP software, which allows their members to lodge EPCs to Landmark.

43 RdSAP Assumptions The EPC is designed so an EPC for one property can be a compared with another. Different people use their house and it’s contents in different ways. EPCs are therefore not specific to the occupants, but to the dwelling itself. Assumptions are made by RdSAP so household behaviour does not impact on the EPC rating Standard occupancy – the actual number of occupants is not accounted for. RdSAP assumes occupancy based on the floor area. This is then used to determine factors like domestic hot water requirement Standard heating pattern – some people have their heating set to 25o all day every day, some people have their heating on for half an hour a day. To avoid this type of behaviour skewing EPC data a standard heating pattern is used. 9 hours heating a day during the week 16 hours a day at the weekend The living area is heated to 21oC and the rest of the house to 18oC RdSAP does not account for energy use by electrical appliances and non-fitted lighting It is assumed these will not be left at the property by the current owner/occupier

44 RdSAP Assumptions RdSAP makes some assumptions based on the data collected by a DEA Window area – a ratio has been calculated which assumes an average window area based on the age of the property and the total floor area U-values – this is the rate of heat loss through windows, walls, floors and the roof of the dwelling. The software assumes U-values for different construction types based on the building techniques used and materials available.

45 RdSAP Documents Appendix S: Appendix T: Conventions:
The methodology list all the data collection fields and their explanations Appendix T: The list of all the improvement measures and their triggers Conventions: The conventions give clear guidance on how assessment criteria is determined and clarify grey areas of the methodology that could lead to variation in interpretation As a DEA all you will need a working knowledge of all 3 documents, and you should understand how, and when to apply the information contained within them.

46 Rating Differences Over time there has been changes to RdSAP they have been made to make the calculation more consistent and accurate We have moved from: SAP v9.83 SAP v9.9 SAP v9.91 (current) Any calculation using newer methodology will be different from a calculation using an earlier methodology. The revisions of the methodology is to better model the energy performance of the property

47 Health & Safety issues for the Energy Assessor

48 Risk assessment As a lone worker working in different surroundings every day, it is of the utmost importance that you carry out a full risk assessment for every survey you carry out.

49 Risk Assessment The Health and Safety Executive (HSE) recommends 5 steps to Risk Assessment:- • Step 1. Identify the hazards • Step 2. Decide who might be harmed and how • Step 3. Evaluate the risks and decide on precautions • Step 4. Record your findings and implement them • Step 5. Review risk assessments and update

50 Assessing Risks When making appointments to inspect properties ask questions to identify potential hazards Consider use of a pre-inspection questionnaire to be sent out with appointment confirmation What questions could you ask the seller over the phone, by or ideally by completing a health & safety questionnaire included with your survey acceptance letter and terms & conditions?

51 Assessing Risks Is the property inhabited or uninhabited?
If uninhabited is it derelict? Are services turned on, e.g. is artificial lighting available? Is the assessor visiting an empty property? What are the parking arrangements – any restrictions? How old is the property, what type and how big is it ? Will all parts of the property be accessible?

52 Personal Preparations
Dress suitably - durable, warm and waterproof clothing. Mobile phone fully charged and switched on; Carry personal alarm; Park close by and put valuables in the boot, park in a legal and safe position; Do not inspect at dusk or after dark; Do not carry unnecessary valuables into the property; Take all appropriate tools/equipment, Let your office know when you are starting and finishing the inspection Lone worker, need to be fully prepared

53 Main risk areas General health and safety issues affecting DEAs;
Travel to inspection - car safety, mobile phone use, journey times Weather- wet, windy, icy Location- unsafe car parking, areas of high social stress, busy road, unlit stairwells Unsafe property- externally- Loose masonry, roof tile, open man holes Lone working- Empty property, ensure someone is aware of your location? Unsafe property- internally- Uneven floor, loose carpets, low ceiling Personal safety- Toxic/dangerous substances, needles and drugs, asbestos Occupants- Threatening, intoxicated Animals- Dogs, other large or potentially dangerous animals Loft/Roof void- Too high (over 3m), located over stairwell Services- Faulty electrical point/meter, gas leak Vermin- rats, insects

54 Surveying Empty Properties
If you are being accompanied by the agent or owner during the inspection, check the person’s credentials When entering the empty building, carry out a cursory inspection of all rooms whilst loudly announcing your presence If you are on your own, lock the external doors when you are inside and keep the keys with you; If you discover an unauthorized person(s), briefly and calmly explain who you are, why you are there and that you are leaving right away. If you discover signs of unauthorized occupation and/or the property is unsecured, leave the property immediately and notify the person responsible.

55 Roof space inspections
When inspecting roof spaces: • Do not site your ladder near any potential hazard Be careful of heavy loft hatches; • Put ladder up properly and extend min. 1.0m above back of ceiling joists; • Wear face mask, check for animal/bird life/wasp nests • Use a strong, bright torch; • Only go in if it is essential and step on the rear of visible ceiling joists. • Watch out for any poorly fixed walking boards; • Look out for low beams/purlins, protruding nails, etc. Do not roll back insulation unnecessarily, just lift a corner for measurement purposes.

56 Ladders Check ladders every time they are used. Refer to the leaflet “HSE Safe use of Ladders & Stepladders An Employers Guide” For their correct use.

72 Roof space inspections

73 Roof space inspections

74 H & S Samples As a group discussions what would you do in the following situations? Then check your answers Scenario 1: The occupant becomes very aggressive and uses threatening language as you carry out your inspection?

75 Scenario 1 You should have your mobile phone and personal alarm with you; Try to stay calm and do not argue; If you feel threatened, leave immediately; Develop a distress signal/password for use between yourself and office staff if you feel it is an emergency.

76 Scenario 2 A 2 storey property with ceiling height of 2.7m, the loft hatch is located at the top of the staircase. Would you inspect the loft?

77 Scenario 2 No, there is a risk of falling a considerable height. Inform the homeowner/occupier that there is too greater risk to access the loft due to it’s location.

78 Scenario 3 The owner shows you into the house and points out their 2 massive dogs, but says, ‘Don’t worry, they wouldn’t hurt a fly’.

79 Scenario 3 You can never be too careful with dogs, politely request that the dogs are kept in another room or outside whilst you carry out the survey. Point out that it is a health and safety precaution, people will generally understand; If not then explain that you will need to end the survey.

80 Scenario 4 You cut yourself when putting up your ladder
The owner says they are a qualified first aider and insists on dressing your cut.

81 Scenario 4 Refuse their help, do not allow anyone else to administer first aid Keep a first aid kit in your surveying equipment

82 Would you inspect this cellar?
Health & Safety Would you inspect this cellar?

83 Health and Safety Low pipework

84 Health & Safety Possible asbestos debris

85 Asbestos Asbestos was extensively used as a building material in the UK from the 1950s through to the mid-1980s. It was used for a variety of purposes and was ideal for fireproofing and insulation. Any building built before 2000 can contain asbestos. Asbestos materials in good condition are safe. Only when fibres become airborne are they dangerous, which happens when materials are damaged. When the fibres are inhaled they can cause these serious diseases: mesothelioma, lung cancer and asbestosis

86 Asbestos As a DEA you should be able to identify asbestos for the purposes of your own safety. If you suspect there is unstable asbestos in a property do not go near it or touch it. If it is located in a confined space such as loft or cellar then consider not accessing the area at all Should not be a common problem in most houses, just need to be aware of it

87 Asbestos Asbestos can be found in a wide variety of products
Asbestos cement Asbestos insulation board

88 Asbestos Textured coatings (Artex) Floor tiles

89 Asbestos Asbestos cement soffit Pipe lagging
