ATTMA has worked with The Energy Conservatory to introduce TECtite version 4.0.59. The updated software sees more data being taken from the software into Lodgement for more detailed statistical analyses. the other big change is the re-introduction of Volume, which allows ACH50 to be calculated directly in the software. The introduction of Volume allows ATTMA members to output lodgements that average the positive and negative tests, whilst averaging the n50 and AP50. This will allow the certificate to be accepted for Passivhaus and Low Energy buildings.
All ATTMA members will be required to update to Version 4.0.59 before 31st December 2018.
