- Historic retrofit with minimal disruption: modernized HVAC and plumbing systems within a 105,000 SF historic building while preserving existing fire ratings, floor assemblies, and architectural fabric—including abandoning embedded ductwork in place and working within tight ceiling and shaft constraints
- Complex phasing and system separation: successfully separated 24/7 State Patrol basement systems and domestic hot water from an existing steam distribution network serving adjacent buildings
- All-electric HVAC strategy: evaluated multiple system types and ultimately implemented a Variable Refrigerant (VRF) heat pump system with integral heat recovery, balancing first cost, constructability, O&M capacity, and energy performance
- Efficient ventilation solution: integrated a packaged heat pump Dedicated Outside Air System, (DOAS) with energy recovery to control building pressurization, reduce infiltration, and lower heating and cooling loads
- Sustainability-driven design: targeted LEED Gold through electrification, energy efficiency, refrigerant management considerations, and reduced water use—aligned with Colorado’s long-term environmental goals
- Plumbing upgrades: implemented water conservation and metering to support LEED requirements and improve long-term operational efficiency
