Our commercial air leakage testing (blower door test) allows us to test larger buildings such as schools, shops, factories, multi story buildings and other various designs and sizes of buildings. For small building the single fan usually is sufficient, larger building will require multiple fans and for large buildings we use lorry mounted fans.
Irish Energy Assessors specialise in air tightness testing, which is now a requirement for all new houses under the current Irish building regulations. Once leaks are identified, we use a number of different methods to improve the air tightness of the house.
