[Audio] NOCN Level 3 Award in Energy Efficiency Measures for Older and Traditional Buildings UNIT 3 Evaluating the option for introducing energy efficiency measures to older and traditional buildings BS 7913.

Justify the selection of energy efficiency measures Legislation and guidance drivers are a common cause of unsympathetic and unrealistic expectations regarding a building along with the use of inappropriate materials to achieve building standards. This can be seen in the application of the following measures: • Wall Insulation that does not consider damp issues • Installation of injected damp proof courses • Replacement of timber floors with insulated concrete • Replacement of windows with double glazed units • Installation of loft insulation • Installation of mechanical ventilation systems.

Justify the selection of energy efficiency measures.

JUSTIFIED Justify the selection of energy efficiency measures • Rationale for why energy efficiency measures may, or may not, have been selected. • The choice of energy efficiency measures is likely to be governed by what are the priorities, although another critical factor will be affordability. • Improvements...will often depend on factors such as whether improvement work can be carried out...without damaging existing fabric . or whether potential solutions are compatible with the existing construction'. • In all cases the 'do nothing' approach should o b considere •nitiall.

• Justify the selection of energy efficiency measures • Specific design, installation or operational features used to minimize the impact of the chosen energy efficiency measure must be considered! MOTIVATION.

Delivery of the Energy Efficiency Measures. Planning the work of installing energy efficiency measures must always be done in consultation with the householder/occupants..

The Roles and Responsibilities in a Retrofit Project The range of roles include; Retrofit Assessor/Domestic Energy Assessor Retrofit Coordinator Designer Installer/subcontractors The professional team will require qualifications, skills, knowledge The installers will require Vocational competence.

The Stages of a Retrofit Project Design Installation Testing Commissioning Handover and handover advice to occupants Ongoing monitoring and fine-tuning, such as post occupancy evaluation Evaluation (including auditing against proposed works) Future maintenance of the building and energy efficiency measures.
