Harshul Singhal
Principal
LEED AP BD+C

As a sustainability specialist, Harshul is wholly committed to sustainability and climate responsive designs. He has considerable expertise in developing high performance design strategies both for new-build and refurbishment projects, and an extensive analytical knowledge of building energy performance and resource conservation strategies.

His substantial body of creative work in the USA, China, India and other parts of the world demonstrates his commitment to sustainable and renewable sources, while his ongoing research and teaching responsibilities enables him to underpin his professional work with scholarship and contribute to lifelong learning.

As an architect and an engineer, he has proved to be a highly effective bridge between the two very different worlds of architectural design and building services, where communication has traditionally been poor.
