The Benefits of Energy Retro-Commissioning for Commercial Buildings

Buildings, while they can withstand the tests of time, aren’t going to stick around forever. For every year that passes, the components within them start to wear out. Eventually, it will come to a point where the building’s owner needs to step in and apply repairs. One of the best solutions for keeping long-standing buildings intact is retro commissioning.

In this article, we’ll explore what is energy retro-commissioning. Then we’ll explore how it can benefit commercial buildings.

What is Retro-Commissioning?

Before we head over to the main topic, let’s understand first what Retro-Commissioning is. So, retro-commissioning is a process that assesses building systems to see if they work as intended. The assessment of factors in the original design and specifications of the structure. Aside from that, it also addresses any changes that occurred since the building’s construction.

Be aware that retro-commissioning services are characterized by knowledge and labor-heavy steps. Despite the intensive knowledge and labor required, the material costs can be either minimal or none. Also, retro-commission can open opportunities for structural improvements - some examples are retrofits and upgrades to equipment.

The Benefits of Energy Retro-Commissioning

Your commercial space can benefit greatly from energy retro-commission services. That’s because this process will ensure that they save a lot of energy in the long run. With that said, let’s explore in detail how this service can enhance energy efficiency for commercial structures.

1. Better Indoor Air Quality

Take note that if your commercial space doesn’t have the right ventilation, its indoor air quality could plummet. The insides of your building could become too muggy or hot for your team to handle. However, through retro-commissioning; you can see whether the HVAC system is working well. Also, you can get a clearer image of your building’s humidity levels.

On top of that, the services will help you in improving the indoor air quality. That’s through improving your commercial space’s ventilation and adding humidity controls.

2. Optimal Temperature Comfort

In connection with the first benefit, maintaining temperature control in your building can lower energy bill costs. An example is a well-optimized HVAC system that circulates cooled air around the building. It will keep your workers comfortable during the warm parts of the year. Whereas during the cold months, hot air is circulated to keep everyone warm and comfy.

Through retro-commissioning, you also prevent hot or cold spots within the building. Thus, everyone who is working within your commercial space is comfortable wherever they go.

3. Promotes Productivity and Safety

Retro-commissioning your commercial space also promotes both productivity and safety. When your workers are comfortable working within your building, they become more productive. Also, through optimal lighting, workers can concentrate better on their tasks. Gone are the days when they were distracted by dim or intense lights or flickering lighting.

In addition to that, fewer accidents will happen. That means your workers are less likely to trip on something along the way. Or in some cases, stumble downstairs by accident.

4. Extends your Equipment’s Expected Lifespan

Be aware that systems such as HVAC or lighting will have a lower lifespan if maintained poorly. For example, if an HVAC system operates non-stop, it will wear down faster. As a result, you will have to replace that system at some point which will cost you a lot. In comparison, retro-commissioning allows you to maintain the same HVAC unit with little to no costs.

Retro-commissioning services will assist you in ensuring that the systems will be functional for years to come. It also ensures that you won’t have to make premature replacements of parts, thus maximizing efficiency.

5. Lesser Need for Repairs or Warranty Claims

It’s best advised that you seek out retro-commissioning services to lessen the frequency of repairs.
