Energy efficiency is more than skin deep: Improving construction quality control in new-build housing using thermography
MetadataDangos cofnod eitem llawn
Objective The objective of the research is to investigate the scope for testing the thermal performance of the building envelope during the construction process using thermography. The purpose of these tests is to enable early identification of performance issues in new residential buildings and support the management of construction quality on site. Methods The application of thermography at different stages during the construction process has been developed through field tests on housing projects in Wales, UK. Results The scope for four types of "in-construction" test have been identified: early stage checks on the installation of insulation; identifying air leakage through the building envelope; assessing insulation continuity and the severity of thermal bridges; and investigating the performance of building services. Conclusion Carrying out tests on a construction site brings practical challenges not usually encountered in thermographic inspections of a completed building. However, useful results can be obtained following the testing approach introduced in the article. Practice implications Early identification of performance issues in new buildings is advantageous so that remedial work can be carried out in a timely and appropriate way. Further research should establish guidelines for the conditions in which reliable results can be obtained using the "in-construction" thermography approach.

Assessing the thermal performance of buildings at the construction stage using thermography. Development and evaluation of a testing approach in the context of new housing in Wales Taylor, Tim (Cardiff Metropolitan University, 2014)At present there are concerns that new housing in the UK under-performs in terms of energy-efficiency. In research studies where the thermal performance of the building fabric has been measured, post-construction, significant ...
Assessing the severity of workmanship defects using thermography and 2-D and 3-D heat transfer models Taylor, Tim; Counsell, John; Gill, Steve; Oakley, Gerraint (Verlag der Technischen Universität Graz, 2013-09)The effectiveness of insulation in reducing heat loss depends to an important extent on the quality of its installation. For new buildings, it is advantageous if the performance of insulation can be checked before construction ...
Combining thermography and computer simulation to identify and assess insulation defects in the construction of building façades Taylor, Tim; Counsell, John; Gill, Steve (Elsevier, 2014-03-12)Thermography is a non-destructive testing technique used to evaluate the thermal performance of buildings, typically post-construction. However, establishing objective criteria for the interpretation of test results is not ...
