Ground water cooling - the most efficient method of rejecting heat in Bermuda's climate and geographical region. This should ensure that the cooling water stays at 72 degrees Fahrenheit.

Multi-stage chiller plant - designed to ramp up and down to meet the load intelligently and remain efficient regardless of the demand.

Variable speed drives - all of the major pumps and fan motors throughout are controlled through variable speed drives to maintain optimum efficiency and to only supply as needed.

Exhaust air recovery - outside air is pre-cooled by the exhaust air, reducing the energy required to cool fresh, outside air.

BAS (Building Automation Systems) and controls - there are hundreds of sensors that measure everything from temperature, flow and pressure to CO2 levels. All of these are processed by the BAS system to keep the building running as efficiently as possible.

Heat harvester - a separate heat pump utilises the condenser water from the chiller to produce hot water far more efficiently than traditional element-based heaters.

Efficient lighting - utilising energy efficient lighting throughout the facility.

Daylighting harvesting - sensors located on the perimeter of the office space dim the lighting based on the ambient light entering the space, therefore maintaining a constant light level and using only as much lighting as needed. This in turn also reduces the heat generated by lighting reducing HVAC (Heating Ventilating and Air Conditioning) load.

Occupancy sensors - sensors throughout sense occupancy and bring the lighting on/off as needed. these in many cases work with other sensors and inputs from the BAS system to reach maximum efficiency.

Metering - the electrical distribution system has dozens of electrical meters that can be trended and monitored, which allows detailed analysis of power consumption.
