E4tech's flagship software product, Lesosai 5.5, has now been developed to meet UK market requirements and named 'ECAT'.

Easy to install and use - ECAT allows designers to check building energy performance compliance with UK Building Regulations Part L2 (non domestic) without previous energy modelling experience. It Incorporates SBEM, the DCLG approved National Calculation Tool.

TLCA feature - ECAT can calculate a building's 'carbon footprint' taking into account lifetime CO2 emissions and energy associated with both the building materials and the building in use.

ECAT includes additional functionality to assist users in optimising energy performance including calculation of thermal characteristics of building envelope elements. ECAT also has a CEN (EN13790) calculation mode.
