Duncan Phillips

RWDI, Principal | Ontario, Canada


Duncan Phillips joined RWDI in 2000 as a CFD Specialist and became Principal in 2009. He is the Practice Area Leader for CFD/ Building Performance/ Ventilation team. This is the group that is involved in simulation of detailed physics including microclimate in urban designs, ventilation, and stack effect in tall buildings. Phillips has led technical work on all continents on Earth and a project on Mars addressing how climate impacts the built environment and vice versa. This frequently leads to the creation of new simulation tools. Measuring and modeling the movement of air around buildings and infrastructure is in Phillips’ DNA.
