Commercial
Commercial
Office buildings represent one of the most common commercial typologies modeled by Enerphi, ranging from compact commercial offices to large-scale headquarters. These projects often require detailed occupancy scheduling, advanced HVAC configurations, daylight-responsive lighting controls, and tenant-specific operational profiles.
| Parameter | Description |
|---|---|
| Typical Gross Floor Area | 5,000–500,000+ m² |
| Typical Number of Floors | 1–6 |
| Typical HVAC Systems | Central Chilled Water Plants, AHUs, VAV Systems, Heat Recovery |
| Occupancy Density | High and highly variable |
| Operating Schedule | 24 hours/day |
Multi-tenant occupancy means schedule diversity needs careful handling. Plug loads dominate end-use breakdown in modern open offices and need realistic EPD modelling. Core-and-shell vs full build-out submissions need different approaches under LEED. WELL pairing is now common. Corporate clients target LEED Gold and WELL Silver as standard.
Case study
30,000 sqm office in Iberia. LEED v4 BD+C. Four floors above grade. VRF system serving fan-coil units. ASHRAE 90.1 Appendix G baseline. Engineered for first-time review.
