About Toby Yang
Building performance expert, educator, and advocate for sustainable living.
I believe that every building has the potential to be more than just a structure—it can be a healthy, comfortable, and energy-efficient home. With a background spanning over a decade in engineering, I have dedicated my career to the science of how we build.

My path to becoming a Passive House professional began with a Bachelor of Engineering in Renewable Energy Systems and a Master of Engineering in Solar Energy Technology. These foundational studies sparked a lasting commitment to sustainability, which eventually led me to specialize in high-performance building standards.

Why I Do What I Do
My work is driven by a passion for sharing knowledge. Whether I am:
