An assessment of energy training for existing dwellings in the UK

1. An assessment of energy training for existing dwellings in the UK Stephen Todd Research Institutefor 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. Energy Ratings Surveyor The NHER Scheme Licences NES Ltd Member Organisation Assessor Examines & monitors Issues NHER Training Organisation Trains

5. Key Features • 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

6. The Quality Scheme

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

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

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

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

11. Data collection & Site Survey • 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

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