BSRIA is proud to announce that the e-learning courses on thermal imaging and airtightness testing are now live.
The courses have been developed with funding from the Horizon 2020 Built2Spec project which was launched in January 2015 and is scheduled to continue until December 2018. The project aims to help meet the EU energy efficiency targets for both new builds and retrofits to reduce the gap between the design and build performance of a building.
As the “Task Leader” on training development and execution in the Built2Spec project, BSRIA has developed the courses. The courses are free to access and can be completed using the links:
Thermal Imaging is the use of special equipment that can detect the heat produced by people or things and use it to produce images of them. Thermal imaging is increasingly being used in the construction industry to check the quality of the building fabric. As well as examining the thermal insulation, it can also be used to test for areas of unusual heat loss or gain and cold areas of internal surfaces that might lead to discomfort, condensation and mould growth. This makes it a useful tool for checking quality in new buildings.
Airtightness is the measure of how much air leakage there is from a building. This is determined by carrying out an airtightness test and the figure obtained from the testing is the air permeability value. Air leakage is the uncontrolled flow of air through gaps and cracks in the fabric of a building which can be caused either by the wind blowing against or across a building, or warm air rising within a building (the stack effect).
Heated air escapes through holes and gaps in the building fabric such as cracks around doors and window frames, poorly sealed electrical and plumbing connections and unfinished service holes. Too much air leakage leads to unnecessary heat loss, and discomfort to the occupants from cold draughts.
Divya Deepankar, Research Engineer, BSRIA Sustainable Construction Group, said:
“BSRIA is delighted to launch two new e-learning courses to help improve industry knowledge on reducing the building energy performance gap. The first course on thermal imaging, concentrates on thermal imaging for building fabric insulation. It aims to help people involved in constructing, owning and operating buildings to obtain the thermal imaging they need when they need it. And to have a basic understanding of the information that can be obtained from thermal images.
The second course on airtightness testing focuses on The Building Regulations 2010 for use in England and the supporting guidance document Approved Document L Conservation of fuel and power. Similar regulations exist in Wales, Scotland and Northern Ireland.
At the end of the course the reader will have a good understanding of: what is airtightness testing, the need for airtightness testing, the theory of air permeability measurement, airtightness testing methods and site requirements and procedures.”
