Thermographic Inspections for BREEAM Compliance

Thermographic Inspections for BREEAM Compliance

Thermographic Inspections for BREEAM Compliance

APT undertakes BREEAM thermal imaging surveys specifically tailored to meet the requirements of BREEAM. The thermography surveys can contribute towards extra credits for overall BREEAM certification and provides visual evidence to the energy performance of a building.

The BREEAM (Building Research Establishment Environmental Assessment Methodology) is a structured to analyse, rate and certify a building’s environmental and sustainability characteristics for both new build and refurbishment projects.


Why Does BREEAM ask for Thermal Imaging Surveys

Thermographic Inspections Survey
The standard that contains the requirements for a BREEAM thermal imaging survey is the SD5078 BREEAM UK New Construction standard. This was launched in 2014 and the section that deals with thermography is contained within thermal comfort for health and wellbeing. The aim of the BREEAM scheme is to mitigate environmental impacts throughout the life cycle of new buildings cost effective and robust manner.

The following text contains the necessary criteria set out within the BRE SD5076 scheme for gaining the extra credit/s for your project.

One Credit – Testing and Inspecting Building Fabric

    1. The commissioning and testing schedule and responsibilities credit is achieved.
    2. The integrity of the building fabric, including continuity of insulation, avoidance of thermal bridging and air leakage paths is quality assured through completion of post construction testing and inspection. Dependent on building type or construction, this can be demonstrated through the completion of a thermographic survey as well as an airtightness test and inspection (see compliance notes 3 and CN3.4. The survey and testing is undertaken by a Suitably Qualified Professional (see Relevant definitions) in accordance with the appropriate standard.
    3. Any defects identified in the thermographic survey or the airtightness testing reports are rectified prior to building handover and close out. Any remedial work must meet the required performance characteristics for the building/element.

We Use Level 3 Thermographers for BREEAM thermal imaging surveys

The importance of using one of our Level 3 trained thermographers cannot be understated as they are trained to be write predictive maintenance and inspection practices and to develop test procedures and ascertain severity criteria. To try and help clients prepare for the BREEAM thermal imaging survey to their building, we have written the following article: How we carry our thermal Surveys on commercial buildings. Here is some more information in regards to the new BREEAM Technical Standards as well as scoring extra BREEAM credits for your new development.

Thermographic Inspections Checklist
BREEAM provides extra points to projects that have a BREEAM Thermal survey undertaken. As not many clients are aware of BREEAM thermal surveys, we have included more information in our ‘What is a BREEAM thermal Imaging Survey’ article. Also to try and help clients prepare for their survey please download the APT Sound Testing Thermal Imaging Checklist.

The Importance of Thermal Imaging Surveys for BREEAM

Thermal imaging surveys are important for BREEAM (Building Research Establishment Environmental Assessment Method) for several reasons:

  1. Verify Thermal Performance: BREEAM environmental assessment method calls for thermal imaging surveys of the building fabric to verify that the thermal performance of a building is as designed.
  2. Identify Energy Loss: Thermal imaging can identify areas of energy loss through the building fabric, which is crucial for reducing the environmental impact of construction and ongoing usage of the building.
  3. Attain BREEAM Credits: Thermal imaging surveys can provide one BREEAM credit towards your building, which can improve your BREEAM rating.
  4. Resolve Heat Loss Issues: Thermal imaging surveys can quickly and conclusively resolve heat loss issues, which is crucial for the ongoing energy efficiency of the building.
  5. Compliance with Building Regulations: Thermal imaging is the best way to assess continuity of insulation or locate air leakage paths in a completed building. This helps project teams comply with the Building Regulations, specifically Part L4 and achieve building control signoff.

The Minimum Requirements for BREEAM Thermal Surveys

BREEAM Thermal imaging surveys should be conducted by certified inspectors to ensure accuracy and compliance. For BREEAM thermographic surveys, a minimum of Level 2/Category 2 certification in accordance with ISO 18436-7 is required. This certification requires approved training, stringent examination, and a minimum of 1200 hours of hands-on experience.

It’s worth noting that Level 1 thermographer is not permitted under ISO 18436-7 to conduct surveys unless working under the direction of a Level 2 thermographer. As of 6th June 2014, the PCN (Civil) Level 2 and ABBE Level 4 Building Thermographer qualifications are also recognised by the UKTA as suitable for BREEAM thermographic surveys. It’s always best to check with your specific BREEAM assessor to check they are happy with your thermographer’s qualifications.

Why Carry Out Thermal Imaging Surveys to ISO 18436-7:2014?

ISO 18436-7:2014 is an international standard that specifies the requirements for qualification and assessment of personnel who perform machinery condition monitoring and diagnostics using infrared thermography.

Here are some key points about ISO 18436-7:2014:

  • It provides recognition of the qualifications and competence of individuals to perform thermal measurements and analysis for machinery condition monitoring using portable thermal imaging equipment.
  • This procedure might not apply to specialized equipment or other specific situations.
  • It specifies a three-category classification programme that is based on the technical areas delineated in the standard.
  • A certificate or declaration of conformity to ISO 18436-7:2014 is often required for professionals conducting thermographic surveys, including those for BREEAM.

The Required Thermal Camera Specification for BREEAM

The minimum thermal camera specification for a BREEAM thermal imaging survey is a resolution of 320×240. However, most professional thermographers use a 640×480 camera, which has 4 times more pixels per image, to ensure adequate analysis. Some services also specify the use of large format FLIR thermal imaging cameras with 45-degree lenses which can cost upwards of £30K. Please note that these specifications can vary and it’s always best to check with the specific requirements of your BREEAM survey.

How Do I Find a Suitably Trained BREEAM Thermographer

There are several resources available to help you find a certified thermographer:

  • IACT (International Association of Certified Thermographers): The IACT maintains a list of certified thermographers and technicians who have had their training and certification verified and accepted by the respective board to undertake BREEAM thermal surveys.
  • UKTA (United Kingdom Thermography Association): The UKTA is an association of professional practitioners of thermography. It provides a list of certified thermographers who are fully qualified in thermal imaging for BREEAM.

Sound, Air & Vent Testing Services

Sound, Air & Vent Testing Services

Sound, Air & Vent Testing in One Seamless Package!

For most new projects you are required to undertake air tightness, sound insulation and domestic extract testing. We are one of the few companies that are UKAS accredited to undertake both Air & Sound testing in compliance to Building Regulations and Standards.

This means we can undertake Air, Sound and Vent Testing Packages during the same visit which provides our clients with substantial cost savings and reducing potential coordination issues. Also, unlike many companies we do not subcontract our works so our testing engineers offer the highest standard possible.

Sound, Air & Vent Testing

Sound Insulation Testing

Pre completion sound testing under Part E of Building Regulations has been a mandatory requirement since July 2003. All new build properties and conversions which were built after this date require 10% of each party wall/floor construction type to be tested. Sound Testing is to be carried out between pairs of rooms separated by party walls or floors.

Sound insulation testing is required to make sure that a residential development can demonstrate acceptable levels of noise attenuation performance. Building Regulations Part E requires you undertake two different types of sound testing including airborne noise (i.e.sound/noise transmitted through the air, such as televisions and conversations between people) and impact noise (i.e. noise resulting from an impact on the floor surface, such as footsteps on the floor). By undertaking the two types of sound testing ensures the dwelling provides a reasonable resistance to the passage of sound.

Air Tightness Testing

Air testing to achieve satisfactory levels of air tightness became a legal requirement in 2006 in England and Wales, under Building Regulations Part L and is becoming increasingly important to help produce greener buildings, via the reduction of carbon emissions as energy is not being needlessly lost from residences via large air leakage paths etc.

Building Regulation Part L defines ‘air leakage’ as the uncontrolled flow of air through gaps and cracks in the fabric of a building. The general public recognise it as draughts. When you lose energy through the building fabric this is known as the building emission rate. Newprojects/developments must meet specific requirements for air testing and emission rates.The usual target for a standard dwelling is 5.0m3/hr/m2; however for commercial buildings the target rate is often much lower – around 3.0m3/hr/m2.

Extractor Fan Testing

Extractor Fan Testing under Part F of Building Regulations has been a mandatory requirement since 2014. All new extract ventilation that uses intermittent extractor fans such as bathrooms, WC and kitchens in new buildings need to have their air flow rates measured on site and the results submitted to the building control body prior to completion and handover.

As buildings become more insulated and air tightness is improved, it is essential that any installed ventilation systems are fit for purpose, balanced and commissioned correctly to ensure optimum levels of operation for the well being of the occupants and prevent on going damage to the properties via mould etc.

We can undertake the extractor fan testing at the same time as the air and sound testing which helps to reduce coordination issues as well as offering a substantial cost saving. You can also be safe the knowledge that the works are being carried out by a UKAS accredited company.
