Why Energy Efficiency Starts With Commissioning

It is commonly assumed that increased energy efficiency is achieved simply by installing the latest equipment or technologies. In practice, this is far from the truth! Without well executed and thorough commissioning, even the most advanced systems can fall short of their potential, resulting in ongoing energy loss and increased costs.

 

Here at Crosscount we consistently find recurring similar issues such as improperly balanced systems, equipment running unnecessarily or a poorly configured controls schedule. An international study carried out and published by the International Energy Agency into Building’s Commissioning Programs shows re-commissioning HVAC systems to ensure they are operating correctly and efficiently can deliver energy savings of 20-30%!

 

Simply put, purchasing the latest plant and technologies is not enough. A diligent and proven commissioning program is the key to unlocking savings, both financially and environmentally.

 

The Cost Of Poor Commissioning

 

As published by the Greater London Authority buildings account for 74% of London’s direct emissions, that’s 21 million tonnes of CO2 per year, of which commercial buildings alone contribute 8 million tonnes. Correct commissioning is integral to reducing this figure.

 

Typical examples of inefficiency include:

 

• Fans and pumps running at full speed against incorrect setpoints.

• Imbalances in air distribution leading to over supply in some areas and undersupply in others.

• Control strategies that are never optimised, causing systems to operate continuously.

 

Recent Case Study

 

On a recent project, targeted adjustments to air handling units delivered an energy saving of almost 20% on fan operation. This was achieved without replacing a single component. Clearly demonstrating how focused commissioning can unlock immediate and measurable benefits.

 

Why It Matters Now

 

With the current geopolitical situation energy costs remain high and organisations continue to come under increasing pressure to demonstrate progress towards Net Zero. Commissioning is no longer a background activity, it is central to the delivery of efficient, sustainable buildings.

 

How We Can Support Your Energy Efficiency Goals

 

Measurable real world energy efficiency is not defined by equipment specification. It depends on how well those systems are set up, tested and balanced. As we move towards sustainable buildings commissioning places itself at the forefront of ongoing optimisation and energy savings.

 

Here at Crosscount our team has delivered commissioning services on projects achieving BREEAM Very Good and Excellent ratings as well as LEED Gold and Platinum accreditations - We also employ a licensed NABERS assessor.
