Energy Efficient Works - Technical Specifications and Considerations
All works must be undertaken by an SEAI registered Contractor in accordance with the technical requirements set out in the Contractor Code of Practice and Technical Specification. The table below sets out the summary performance requirements, however you are strongly advised to consult with your appointed Contractor for details, noting that homeowners cannot unilaterally waive any of the scheme requirements.
| Measure | Summary Requirement |
| Insulation | Attic Insulation | Ceiling Level: Target U-Value ≤ 0.16 W/m2K
Rafter Level: Target U-Value ≤ 0.20 W/m2K |
| Wall Insulation - Cavity | NSAI Agrément certified system
Target U-Value ≤ 0.27 W/m2K |
| Wall Insulation - External | NSAI Agrément certified system
Target U-Value ≤ 0.27 W/m2K |
| Wall Insulation - Internal Dry Lining | Target U-Value ≤ 0.27 W/m2K |
| Internal and external wall insulation grants are not single grant amounts but rather different grant levels will apply depending on the applicant’s house type. |
| Heating System | High Efficiency Oil / Gas Boiler with Controls upgrade. | Upgrade comprising - Boiler seasonal efficiency ≥90% (as indicated on the SEAI HARP database)
- Two zones (space and water) with 7 day programmer (time / temperature)
- Time / temperature control of electric immersion
- 1 additional zone OR installation of sufficient TRVs
|
| Heating Controls Upgrade only | Upgrade Comprising - Two zones (space and water) with 7 day programmer (time / temperature)
- Time / temperature control of electric immersion
- 1 additional zone OR installation of sufficient TRVs
|
| Solar Heating | Product (panel) must be on SEAI registered product list and supplying > 10 kWh/ m2/Yr |
| Building Energy Rating (BER) | Use registered BER assessor and BER published on National Administration System |
