1 An assessment of energy training for existing dwellings in the UK Stephen Todd Research Institute for the Built & Human Environment, University of Salford, UK

2 Introduction Background to Energy Labelling Key features of The Standard Assessment Procedure (SAP) and National Home Energy Rating (NHER) BREDEM Model Training skills Assessors and monitoring

3 Key Features

4 The NHER Scheme NES Ltd NHER Training Organisation Member Organisation Assessor SurveyorEnergy Ratings Licences Examines & monitors Trains Issues

5 NHER Surveyors or Assessors are required to pass the appropriate examination The skills required depend on whether the information is from drawings and specification or if a site survey is undertaken The site examination therefore tests the ability to collect the necessary information Site Assessors have all the skills of the site surveyor but has had further training on the software Key Features

6 The Quality Scheme

7 1.ISO EN 900 scheme in place for the administration of the scheme, including a legal agreement with members. 2.All Assessors and Surveyors need to pass a professional examination 3.All training delivered by approved trainers 4.Monitoring of Assessors work via certificates 5.Government endorsed software.

8 Training 1.ISO EN 900 scheme in place for the administration of the scheme, including a legal agreement with members. 2.All Assessors and Surveyors need to pass a professional examination 3.All training delivered by approved trainers 4.Monitoring of Assessors work via certificates 5.Government endorsed software.

9 Pre-Course Study Ideally delegates will have: 1.Read the training manual especially the section relating to completion of the survey form. 2.Some experience in surveying domestic properties and can identify standard construction types. 3.Less experienced candidates will need to spend more time reading the background material 4.One area that is traditionally difficult is the correct identification of heating systems and their controls 5.The training manual includes Survey Forms which can be used on practise dwellings

10 Data collection & Site Survey 1.Accurate completion of survey form or use of handheld e.g. Property Tectonics/University of Salford configuration 2.Dimensions of the dwelling including insulation, heating system, hw, lighting and appliances 3.Some intelligence built into the software e.g. window areas 4.Knowledge of applicable improvement required

11 Data collection & Site Survey 1.U-values – Where specifications are available can be calculated. Assumptions made for existing properties:

12 Site Survey The Surveyor must distinguish: Brick patterns – cavity, filled cavity or timber frame Primary and secondary heating (including controls) Use ‘extended data’ appropriately e.g. window areas, L50 Test Data Occupancy and heating pattern

45 Conclusions 1.Described an overview of skills and training requirements 2.Acquisition of site data to prescribed conventions 3.Trainers should develop an awareness of type/level of delegate 4.Training can be tailored to groups with generic skills 5.Overriding objective is to provide qualified professions working to appropriate quality standards to operate in the energy assessment market
