Greenbuild is owner operated by Gavin Ò Sè. Greenbuild has been operating building testing services since 2006 when Gavin saw in his own building work the need for a better way to quantify how well the houses were being built. The air pressure testing equipment used is calibrated and operated by trained professionals. The thermal imaging equipment is also operated by trained personnel. In terms of building information services, they have also had training and some experience in alternative construction methods as well as the more usual materials and methods.
