Engineering Building Performance, Systems & Products.
We help engineering firms, building developers, and HVAC equipment manufacturers with building energy modeling, mechanical systems engineering, thermal product development, and BIM documentation.
What we've delivered.
Building energy modeling, mechanical/BIM coordination, and performance analysis work for engineering, building, and construction teams.
LEED EAp2 Energy Modeling for a Mixed-Use Office Tower
DesignBuilder · EnergyPlus
A whole-building energy model developed for a 24,000+ m² mixed-use office tower to support LEED EAp2 performance evaluation. Baseline and Proposed models were built in DesignBuilder/EnergyPlus under ASHRAE 90.1-2016 Appendix G, with detailed representation of HVAC, central plant operation, site energy, utility cost, GHG emissions, and model performance validation.
