Zack is a building performance expert, working and challenging the field of low-energy domestic buildings for over 13 years. He undertook his academically commended PhD research on the contribution of user behaviours to building performance with Buro Happold Engineers. Subsequently, he worked with Willmott Dixon Energy Services, pioneering performance-feedback approaches, in particular on their wide-scale social housing retrofit schemes.
