BREEAM Thermography Surveys In London
Infrared Thermography is non-invasive, non-contact and hence non-destructive. It can be used to scan large areas quickly – such as large warehouses) and identify anomalies such as defective insulation or areas of dampness and trace and record paths in a way that other methods cannot.
Carrying out a BREEAM Thermography Survey in London can be a cost effective way of gaining that often much needed credit. Thermographic Surveys can diagnose problems after
the building envelope is complete. Thermographic Surveys can be carried out before and after work is completed to show improvement in the building envelope. Non-intrusive and large areas can be surveyed in a relatively short period of time. Thermography is a powerful tool for clients to check the performance of the building envelope.
Thermography is a type of photography which is based on infrared wavelengths (as opposed to visible wavelengths). Conventional photography relies on reflected energy from a light source, whether it’s artificial lighting or the sun, which is visible to our eyes. Thermal imaging relies on radiated energy in the infrared (IR) spectrum which cannot be seen by our eyes. All objects emit radiation energy within the IR spectrum and this IR radiation can and does vary depending on the temperature of that object.
As we cannot see the infrared (IR) spectrum with our eyes, we need to use a device which can detect the “invisible” energy. A thermal imaging camera can do this. The camera builds a pixelated image (much like a normal camera) of the IR radiation which allows us to “see” and measure the apparent temperature of the surface.
Ascertaining the surface temperature of a building helps our thermography engineers to decipher what is actually being detected, such as missing insulation, thermal bridging and other building heat loss aspects. We can also detect objects which contain moisture using different thermographic techniques.
Building thermography is usually a qualitative methodology, that’s means we look at temperature comparisons rather than absolute temperatures. Therefore, thermal images are often used with the temperature scale removed, as it’s more important to highlight the anomalies, patterns and relative temperatures. The anomalies show up by using high contrast colours. The colour scale shows relatively cold as black/purple/blue through to relatively hot as yellow/red/white.
When used in conjunction with other diagnostic tools such as air tightness testing thermography can be a very quick tool to highlight air leakage paths so targeted air sealing can be undertaken to improve the air tightness of buildings, thus lowering heating bills and your carbon footprint. Air Pressure Testing has ascertained the thermal performance of many types of building. APT conduct infrared surveys on commercial and residential buildings as well as listed buildings to the latest high performance Passivhaus structures.
Our main clients that require Thermography Survey in London are main contractors, developers, architects, engineers, building control facility management companies and councils and many others to verify new building performance, help drive refurbishment programs, gain BREEAM points and improve building performance and comfort.
Thermography Survey for BREEAM
Conducting a BREEAM thermographic survey can be one of the easiest and cost effective ways to generate BREEAM credits. Thermographic surveys are now a feature of BREEAM the environmental assessment method and rating system for commercial and domestic buildings. We have undertaken a large amount of thermographic surveys in compliance with the latest BREEAM schemes in London. We also work proactively with clients to ensure a successful outcome.
BREEAM New Construction and BREEAM 2012 Domestic Refurbishment award credits for thermography surveys carried out by a Level 2 certified thermography engineer. The way each scheme works with respect to awarding points for thermography is slightly different. The very latest BREEAM 2014 UK New Construction scheme provides BREEAM credits for thermographic surveys but is in a slightly different way. A quick summary is below:
BREEAM 2011 Scheme for New Construction.
This new BREEAM technical guide describes an environmental performance standard against which new, non-domestic buildings in the UK can be assessed, rated and certified. It grants 1 BREEAM credit for a BREEAM thermographic survey in London as part of Man 01 Sustainable Procurement and states the following:
1. The main contractor accounts for a thermographic survey within the project budget and programme of works.
2. Once construction is complete a thermographic survey of the building fabric is undertaken in accordance with the appropriate standard and by a professional holding a valid Level 2 certificate in thermography.
3. The survey confirms:
a. Continuity of insulation in accordance with the construction drawings
b. Avoidance of excessive thermal bridging
c. Avoidance of air leakage paths through the fabric (except through intentional openings)
d. Any defects identified via the post construction inspections are rectified
The BREEAM UK New Construction 2014 Scheme describes an environmental performance standard against which new, non-domestic buildings in the UK can be assessed and achieve a BREEAM New Construction rating. Of the 4 credits available in Man 04 Commissioning and Handover, 1 BREEAM credit is available for Testing and Inspecting Building Fabric through post construction testing and inspection.
The integrity of the building fabric is accessed and assured through the undertaking of a thermographic survey as well as an airtightness test, Air pressure Testing has engineers that are hold Level 3 certification and we are UKAS accredited for Air Tightness Testing.
We have extensive experience of assessing thermal performance of many types of building. We conduct London infrared surveys on large commercial buildings such as schools and residential buildings such as blocks of flats. Our main clients are architects, main contractors, developers, building control to verify new building performance and improve building comfort.
Infrared Thermography Surveys on Building Envelopes are incredibly useful as it provides the most rapid means to identify unintentional air leakage pathways in a building envelope.
The benefits of infrared thermography in this context are:
a. Air leakage pathways within a completed construction can be identified and rectified prior to air permeability tests, reducing the risk of repeat testing being required.
b. Depending upon the nature of the construction, even a building that meets or exceeds air tightness requirements may still be at risk of deterioration due to air leakage and subsequent condensation. Identifying where air leakage is occurring can be critical.
c. Air leakage pathways can often indicate rainwater ingress pathways adding to the potential benefits of an infrared survey.
