Building Science

Building Science is the focus on a building's technical performance. This discipline brings together a deep understanding of buildings, building systems and their impact on energy efficiency, comfort, health and sustainability. Building Science engineers make informed design decisions before construction begins and deliver innovative design concepts that result in high-performance buildings that respond and adapt to their environment.
