The Case for Optimization

Energy costs too high?  Look closer at your HVAC system

When was the last time you looked closer at how effective your building’s air conditioning or refrigeration system is operating?

If you can’t recall or if it’s been a long time, you’re in good company:  Most building owners and facility managers don’t pay much attention to how efficient their HVAC and refrigeration systems are operating until something goes wrong.

However, this also means those systems are very likely running far below their optimized performance parameters, and that is costing you a lot more energy (i.e. money) to keep them working every day.


The percentage you could potentially save on electricity by optimizing your HVAC system

Inside Your HVAC System

What exactly is ‘Advanced chiller and chilled water loop optimization’?

If your building’s HVAC system was a body, the chiller plant would usually be considered the “heart”. 

Not only is the chiller plant the main source of cooling, but its power requirements make up a large amount of a building’s energy consumption.  

This makes chiller optimization critical to achieving better building energy performance. 

A primary challenge with achieving chiller optimization is recognizing that your chiller plant is very likely not operating at it’s designed ‘temperature differential’, which is the temperature difference between the chilled water supply and the chilled water return – called the “Delta T.”

It is not uncommon to find chiller plants operating at far less than optimal levels (at a lower Delta T).   This can be caused many factors, including how the chiller equipment is controlled or how the air handlers, fan coils, etc. are operating.

The key to chiller optimization starts with the operation of the chillers and chilled water pumps.  A variable-primary chilled water system is a more efficient setup because only one set of pumps is used to move water through the chillers and the building systems.

A strategic, expert-level chiller optimization program can address many potential issues before they require expensive repairs and/or increase in energy bills.  Building owners and operators who want to keep costs under control should consider  an advanced chiller optimization strategy.

Smart Benefits

Lower Electricity and Maintenance Costs

Advanced chiller optimization is commonly recognized as a proven and reliable way for buildings and facilities to reduce the amount of money they are paying to run and operate their HVAC and refrigeration systems.

Most existing systems waste money cooling a building (as much as one out of every three dollars spent).  We remove that inefficiency, increasing system capacity and delivering long-term energy savings.

Clients typically see electric savings from 10% to 40%, and wear and tear on chiller equipment – motors, pumps, compressors, fans – are dramatically reduced, extending their lifespan.

Improved Occupant Comfort

Buildings and facilities of all sizes are under pressure to keep energy costs low while still delivering occupant comfort.

Advanced chiller optimization allows building and facility operators to regulate and maintain the right temperature with incredible precision. 

In some cases, clients have reported as high as a 90% reduction in comfort complaints.

And with the decrease in hot and cold calls, building and facility support staff have more time available for preventative maintenance activities. 

Environmental Sustainability

As the marketplace becomes increasingly aware of the impacts brought on by high energy consumption and its associated waste, building owners and operators must be diligent stewards of how their property impacts the environment as a whole.

Advanced chiller optimization has been a sensible and proven path to helping our clients achieve their environmental objectives – not only through reductions in energy consumption, but with the capacity to effectively measure and track energy consumption trends and proactively anticipated potential demand requirements.

Optimization with No Investment

No Budget?  No Problem.

Through our Energy Savings as a Service turnkey solution, your building or facility can receive a complete chiller or chilled loop optimization solution without the risk of using your own capital to invest in any equipment OR pay for any of the ongoing maintenance.

Instead, Onsite Utility Services makes the investment for you, freeing up your capital for other more pressing issues.

The equipment and installation costs are then taken from the new energy savings that are generated through the lower heating/cooling costs.

You enjoy reduced operational costs derived from lower energy utilization, coupled with no equipment maintenance expenses – all without spending or risking any of your own capital.

No Investment

There is no up-front or out-of-pocket expenditure – we make the investment for you.

No Maintenance

All the service & maintenance costs are fully included during the entire service term.

No Debt

It’s not a loan or traditional ‘financing’, so you get complete off-balance-sheet flexibility.

Frees Up Capital

Enjoy the benefits of reduced operational costs without the risk of spending your own capital.
