Air Pressure Testing

If you are on a project of over 30 properties, individual property in a conservation area a listed building or a high rise your jobs will fall into Annex XX Risk Path C.  For all Risk Path C jobs that are lodged with Trustmark, there is a requirement to provide pre and post-air pressure testing to ensure that the PAS2030:

Clause 8.5.1

a test of the air permeability of the building envelope, using an approved method, including identification of key leakage locations;

and

Clause C.2.4.

if the proposed energy efficiency improvement measures are either intended to reduce the air permeability of the building envelope below 5 m3 /m2 h at 50 Pa or might do so, then existing IEV or PSV as described in C.2.3 (an acceptable, complete ventilation system) shall be assessed as inadequate

Retrofit Coordinator UK will provide air pressure testing completed using the traditional door blower system, enabling you to pinpoint areas of potential thermal bridging and demonstrate compliance with Clause 8.5.1

Our Air Tightness Testing partners specialise in Part L1A, L2B and E & Part F Building Regulations, the requirements for commercial and domestic dwellings.  They are regularly used by developers, self-build and multi-national companies for a number of services:

• Air Permeability or Air Tightness Testing
• Acoustic Sound Insulating Testing
• SAP Calculations
• Ventilation Testing
• Passiv Haus / Low Energy Testing
• BTS03 / HBN04 Isolation Suite Testing

Thermal Imaging

A thermal survey can provide many benefits for any building type, whether residential or commercial.

By utilising a state-of-the-art thermal imaging camera, it is possible to detect and identify a number of anomalies within your building which are normally not visible to the naked eye e.g. Heat loss, air leakage, defective insulation and cold bridging.

Thermographic measurements taken by the thermal imaging camera will record the temperature variations of the building’s envelope, with the resulting images helping our engineers to determine where remedial works may be required.

They can also operate as a quality control tool, ensuring that insulation that the insulation has been installed correctly Building Thermographers offer the highest level of qualifications and experience to satisfy any requirement, including BREEAM, Continuity of Insulation, investigating thermal comfort issues and diagnosing building faults.

Domestic EPCs

The EU Directive on the energy performance of buildings (the Directive) came into effect progressively in 2007. Its implementation remains an important part of the strategy to tackle climate change. The current requirements are set out in the Energy Performance of Buildings (England and Wales) Regulations 2012, which came into effect on 9 January 2013, although they have been amended since, and the Building Regulations 2010.

Key points

• Many publicly funded Domestic Retrofit Schemes require a post-installation EPC.
• An EPC is valid for 10 years and can be reused as many times as required within that period.
• The regulations require an EPC to be commissioned if there is no valid EPC for that building before a building is put on the market.
• Before marketing a building for sale or rent a person acting on behalf of the seller or landlord (for example, the estate or letting agent) must be satisfied that an
• EPC has been commissioned for that building.
• An EPC must be produced by an accredited energy assessor who is a member of a government-approved accreditation scheme.
• All advertisements in the commercial media must clearly show the energy rating of the building (where this is available).
• The regulations require an EPC to be given free of charge to the person who becomes the buyer or tenant of the building.
• An EPC shows the energy efficiency rating on an A–G rating scale for a building.
  The EPC includes recommendations on how to improve energy efficiency.

Non-Domestic EPCs

Since 1 April 2018, landlords of non-domestic rented properties have only been permitted to grant a new tenancy or to extend or renew an existing tenancy, if their property has at least an Energy Performance Certificate (EPC) E rating, unless they have registered a valid exemption.

From 1 April 2023, the requirement for non-domestic landlords to obtain at least an EPC E rating, unless they have registered a valid exemption, applies to all privately rented non-domestic properties (even where there has been no change in tenancy).

If your property is currently empty, and you are not planning to let it, you don’t need to take any action to improve its rating.  If you are planning reletting your non-domestic property you will require an EPC, if the EPC falls into a G or a G banding you will need to take steps to improve the energy efficiency of the property.

CPH Retrofit can then recommend a package of measures required to ensure your property reaches EPC Band E.
