I study how buildings perform: what the model predicts, what sensors measure, and why they disagree.

關於(01) Background
Hi, I’m Marco.
I’m from Hong Kong and study Honours Mechanical Engineering Co-op at the University of Waterloo. My co-op terms have taken me from BIM at Hong Kong International Airport and WSP in Toronto to water-treatment engineering at Chevalier in Kwai Chung.

2.1Project one
ME572 · 2026
Whole-Building Energy Model
A 5,000 ft² Rochester office, benchmarked against ENERGY STAR, then pushed through 17 parametric runs.
- Runs
- 17
- Peak cooling
- −31.5%
- Emissions
- +10.6%
2.1Shading
Facades that react to the sun
This tower’s adaptive shading closes against low sun and opens when the outside air helps. Responsive facades like this are what I want to research.
2.1Envelope
One variable, three answers
Lower glazing SHGC: cooling −31.5%, emissions +10.6%.
2.1Air
Outdoor air is a heating load
30 → 10 cfm/person barely moves cooling but swings emissions 18 points.
2.1Lighting
Less light, more heat
−25% lighting power: EUI −6.3%, heating +13.6%.
2.1Measurement
Predicted, not yet measured
Next: instrument real buildings and explain the gap, starting with Hong Kong.
2.1All runs
Every run, side by side
The building changed one thing at a time. Here is the best tested value of each parameter against the control, or all 17 runs at once.

Office Lighting Layout
A 48 × 34 ft office lit to 52 fc under the 0.6 W/ft² cap. Then COMFEN showed what less light does to heating.
