HVAC Energy Use

Heaters, chillers, pumps, fans, pneumatics, controls, and any other loads that constitute the HVAC system.

Building Energy Use

AEM helps determine energy consumed in a building for heating, ventilating, and air conditioning (HVAC), indoor lighting, facade lighting, domestic hot water (DHW), plug loads, people movers, and other building energy use, excluding Process Energy Use and Cogeneration Losses. When a building has multiple functions (e.g.,office, retail, laboratory, parking), the energy use may be itemized for each Functional Area for comparison to other buildings of the same types. Alternatively, the building may be analyzed as a whole and reported as a mixed-use building. Thereafter providing the best possible solutions for your company.

HVAC

(Heating, Ventilating and Air Conditioning) systems have evolved and gotten better with technology.

SYSTEM ENERGY EFFICIENCY

Depending on the application and occupancy, a higher SEER (Seasonal Energy Efficiency Rating) for equipment is preferable most of the time. A higher the SEER means more expensive equipment, but the lower operating cost is a win for energy and your occupants.

SYSTEM MAINTENANCE

When selecting the right HVAC system, keep in mind the occupancy type vs. the long-term cost of maintenance. Chilled water/boiler systems will require preventive maintenance for a chiller, cooling tower, boiler, heat exchanger, etc to a greater extent than a DX (direct expansion) unitary system. A DX split or packaged system will be a handful of components that are readily available and replaced at a minimal cost.

INSTALLATION COST

Most of the HVAC system cost is in the equipment and control system. Both are important to system sustainability. Duct systems normally require little maintenance if quality materials, closure systems, sealants and higher “R” value insulation are used. Providing the correct type of air distribution is just as vital as selecting the equipment and will maximize coverage, eliminate the draft effect on occupants as well as air noise transmitted from the device due to a high velocity (fpm) of air.

BUILDING AUTOMATION

Each control system has a place in the “right choice column.” A commercial building operating from 8 a.m. to 5 p.m. will have different needs than an institutional building or medical facility. The challenge with a fully automated system is it’s almost always proprietary in nature and can only be serviced by the brand vender, leaving the building owner with no other option for value shopping. A stand-alone zoned system with programmable thermostats is fairly user-friendly and can be serviced by any commercial company. This dramatically reduces long-term replacement and/or maintenance cost for the end user.

HVAC Energy Use = Heating Energy Use + Cooling Energy Use + Air Distribution
