This thesis investigates the role of the Architect in the operational performance of non-domestic buildings claiming to be low energy. The study used mixed research methods and built on the author’s previous work with the IEE-funded iSERV project to understand and quantify the influence architects exercise on the operational performance of low energy buildings. The mixed research methods comprised literature based research and a comparative case study investigation of two well monitored buildings,one constructed before and one after energy efficiency became a focal point of building regulations and energy policy. The later building promoted its low energy design aspirations. The comparative case study investigation traced the energy flows in the selected case studies at building, system, component, space and activity level. It also examined the indoor environmental quality achieved and occupant-perceived satisfaction with the indoor environment. The study demonstrated how energy was used in the selected case study buildings and quantified the influence of stakeholders on their energy performance. The thesis concluded that architects have only a partial influence on the non-performance of low energy buildings, with occupant behaviour and facility management also influencing a significant portion of the total energy consumption. The findings of this research suggested that the architect’s design decisions influenced approximately 23% to 28% of the total annual electricity use and nearly the total heat energy use in the recent low energy building studied. For the conventional existing building studied, these proportions became approximately 43% to 47% of the total annual electricity use and 94% to 97% of the annual heat energy use.
