The Importance of an Energy Assessment for Commercial Buildings

Building owners and property managers that take on the responsibility of limiting energy consumption can be looked at as environmental leaders. While energy management adds extra tasks to everyday lists, the benefits outweigh the time and money spent, which is usually returned in savings.

There are numerous areas to take into consideration when it comes to commercial buildings, and being that commercial buildings are generally large, the impact can be large as well. These areas include the HVAC system, chillers, windows, lighting, electrical equipment, and any other factors that may be contributing to the building’s energy consumption.

While there are various ways to be involved with bettering the environment outside of where you live and work, starting in a place that you occupy everyday has the potential of having long term results if the actions are carried through as often as you’re there.

Consider creating an outlined approach for managing the building’s energy with these areas in mind:

Identify Sustainable Alternatives Where Energy is Being Used:

  • Are there upgraded, energy-efficient versions of the equipment you can be using instead?
  • Could you use different settings on the equipment?

Assess the Purpose of Every Area:

  • Is the lighting being utilized in every room?
  • Is the size of the HVAC system an adequate fit for the building and its purpose?

Evaluate Maintenance Plans:

  • How frequent are the utilities maintained?
  • Do the maintenance technicians practice with energy efficiency in mind?

Look for Possible Areas of Energy Loss:

  • Are the building’s windows sealed properly?
  • Is the equipment too old for efficient functioning?

These are questions you should ask yourself if you’re trying to assess energy consumption and find that alternative route to save not only energy, but money as well.

After addressing these questions, you may find yourself planning to make some changes. Here is the information you should know for doing so:

Energy Efficient Equipment: Whether it’s the HVAC system, the utility lighting or the other various appliances being used in the building, there are energy-efficient options to consider. This includes ones with ENERGY STAR ratings, which match the standards set by the government.

Settings & Thermostats: Just by being knowledgeable about specific settings and the different types of available thermostats, you can be saving a substantial amount of energy. Depending on the type of building and the function(s) of the building, settings can be applied to use less energy in an area that doesn’t need it. The same idea goes for thermostats. Programmable thermostats allow for precise regulation of energy consumption. This means making sure the temperatures aren’t set too high or too low when the building or part of a building isn’t in use. Programmable thermostats keep the location comfortable when needed, but help save energy when it’s not.

Lighting: It’s better to be the building that turns its lights off when it isn’t being used, than a building that keeps them on 24/7. It’s also important to consider energy-saving types, such as LED or solar. With these kinds, you can also invest in timers and dimmers.

HVAC Size: According to ENERGY STAR, “at least 25% of all rooftop HVAC units are oversized, resulting in increased energy costs and equipment wear.” Determining what size HVAC system the building needs is a job for a professional technician, and it’s an important part of the overall building assessment.

Maintenance: Building maintenance is not only important for saving energy and money, it’s important for the building’s health and those occupying it. This includes electrical, HVAC, plumbing, etc. While there are tasks you can manage on your own, there are specific tasks that are recommended for the hands of a professional technician. Whatever the area, it’s important to have maintenance scheduled. Having a definite schedule helps to prevent sudden issues, which prevents sudden energy loss as well.

Technicians: Certain companies know the importance of offering energy-efficient services. This means that they practice in ways that are beneficial for the environment. Research the companies in your area and look for the ways they’re working to save energy and you money. This is an important quality, and more companies are beginning to realize that.

Windows, Replacements & Other Areas of Loss: Other ways to assess energy is by looking into the not so obvious. This includes windows, old systems that don’t show signs of stress until it’s too late, and too many running appliances and pieces of equipment causing heat. If windows aren’t sealed properly, especially in summer and winter, your HVAC system may be working harder than it has to in order to reach the desired temperature. Leaks of hot or cold air will cause this. Another concern are systems that don’t show signs of stress. If the system is old, it’s definitely recommended to have it maintained, even if you think otherwise. The inside has moving parts that may be working very hard to keep it running, and the machine giving out might be the first sign if you wait too long. Lastly, there may be too much heat. Too many heat producing appliances or pieces of equipment may cause the air conditioner to work harder, similar to an open window on a hot summer day.

Commercial buildings don’t function alone, they need the help of energy, and all building owners and property managers can help conserve it.

  1. It is true that many rooftop units are oversized for the need, however changing out that equipment can be a costly undertaking for the owner. I think it’s a good idea to see if that equipment is running as efficiently as it can be in the circumstance. Savings gained here can then be put towards the ultimate replacement of the equipment.

  2. Couldn’t agree more with John. However, facility managers are so busy and they loose focus on energy management while putting out fires all the time. Even a part-time person responsible for energy management helps immensely in achieving the results.
