Air Testing & Leakage
Air Pressure Testing is not just for new-builds, it can be used to find leakage areas in existing buildings, improve the air tightness and improve/stop drafts..more
On Construction EPCs
By law, Energy Performance Certificates can only be produced by an Accredited On Construction Energy Assessor.*
People who are currently doing SAP calculations to show that they meet Target Emission Rates as part of Building Regulations will need to join an accreditation scheme before they can produce EPCs. The accreditation schemes protect builders and potential homeowners by making sure Energy Assessors have the appropriate skills to carry out energy assessments, and that EPCs are always of the same high quality.
So that they can produce an EPC, the On Construction Energy Assessor will need to use an approved version of the SAP software. The current SAP software is being upgraded so that it can produce EPCs. Energy Performance Certificates must be registered and stored in the national register at www.EPCregister.com with a unique reference number. This must be done by the On Construction Energy Assessor in conjunction with their accreditation scheme.
*An On Construction Energy Assessor will not need to visit the property to produce an EPC. The EPC will be the result of the As Built check which is an extension of the SAP calculation needed for Building Control.
If you have had the design sap calculations done already however you are unable to get hold of the person who did these calcs to produce the on construction EPCs or maybe they are simply too expensive or they are not qualified as an OCDEA to lodge new build EPCs with an official RRN, then look no further we can help contact E2 Consultants. To date we have undertaken thousands of On Construction EPCs on small and large schemes throughout England, Scotland & Wales.
An On Construction EPC certificate records how energy efficient the property is as a building and provides A – G ratings. These are similar to the labels now provided with domestic appliances such as refrigerators and washing machines. On Construction EPCs are produced off plan using full SAP methodology (standard assessment procedure) this is more accurate than RdSAP as used in existing dwellings because all the build specification is available to the assessor. Any new build EPC done using RDSAP methodology will not be accepted by building control.
On Construction EPCs (SAP)are required before a new build can be certified by building control, EPCs are also required for the sale and let of new build properties, new build properties can be marketed at the design stage as the assessor can produce a PDA (Predicted Energy Assessment) off the plan and build specification before the property is built. The property has to be completed before the full EPC can be issued. New buildings must comply with Building Regulation Part 1LA and the Air Tightness Test result is calculated in to the EPC calculation, the result of the Air Tightness Test affects the overall rating.
On Construction EPC can also be known as:
New Build On Construction Domestic EPC, Domestic On Construction EPC, New Build On Construction EPC, New Build EPC, New Build Domestic EPC, Predicted Energy Assessment, PEA,
