Building / HVAC System Schematic
Project Overview
Designed an HVAC system for a 12-story residential condominium, balancing comfort, energy efficiency, and sustainability.
Evaluated conventional, GSHP, and hybrid GSHP systems to compare energy use, greenhouse gas emissions, and operational costs.
Key Outcome: The hybrid GSHP system reduced GHG emissions by ~90% compared to conventional systems.
Challenge
- Provide reliable heating and cooling under peak summer and winter conditions
- Reduce operational costs and environmental impact
- Integrate ground-source heat pump technology efficiently within a multi-story building
