What's New in HVAC ... the Standard 180 P!
So much depends on the air we breathe – our comfort, health and happiness. Carl Wolf, President of Service Unlimited, Inc. and past President of Delaware ASHRAE, states that, "... proper HVAC maintenance plays an important role in creating a healthy indoor environment and lowering energy costs. Carl also states that “inconsistent practices in inspection and maintenance of HVAC systems are common in the building industry. As a result, systems frequently operate outside optimum performance, without providing the energy efficiency, thermal comfort and indoor air quality they were designed to provide."
Because of this, ASHRAE is currently developing Standard 180 P; the Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems. The Standard 180 P would establish minimum HVAC inspection and maintenance requirements that aid a system's ability to achieve acceptable thermal comfort, energy efficiency and indoor air quality in commercial buildings.
This standard practice would benefit occupants and also ensure that indoor environmental conditions are maintained as energy-efficiently and cost-effectively as possible.
Highlights of the proposed standard include:
- Responsibility for compliance with the standard would be on the building owner; a common reason given for lack of maintenance is lack of sufficient resources available to maintenance personnel.
- Each building must have a written plan that addresses 57 inspection/maintenance items required if those components are present in the building (for example, if a building has cooling towers, items dealing with cooling towers are mandated as part of the plan).
- An additional list of 563 optional inspection and maintenance items that building owners/operators may wish to consider when preparing their individual plan.
- The standard especially concentrates on those factors that impact thermal comfort, energy efficiency and indoor air quality so as to promote sustainability.
Service Unlimited, Inc.'s Green Comprehensive Maintenance Programs will meet or exceed Standard 180 P, ensuring that you are in compliance, energy efficient and saving money.
