Energy Recovery

There's a GOLD MINE in Your Basement!
(...or on your roof..., or in your mechanical room.) And we will pay to help you find it!

You spend money every day of your life on one or more of these things:
  • Heating or Cooling your home or office
  • Heating your swimming pool or spa
  • Paying for electricity to run your factory, keep the conveyer belts turning, run the elevators, etc.

Somewhere in your home, office, or place of work is a mechanical room filled with equipment that heats and cools the building. In large buildings or factories the heating, ventilation and air conditioning (HVAC) equipment can be immense and will consume large amounts of energy. But the separate subsystems are rarely interconnected and they are not "smart" enough to know what the other subsystems are doing.

Think of a hotel as an example. It's a big building with a lobby and a restaurant, lots of hallways and perhaps thousands of individual rooms. The kitchen consumes lots of natural gas to cook food, and a lot of the extra heat from burning that gas goes up the exhaust chutes from the giant fans that eject smoke and odors. And the occupant of one room might find that 76 degrees F is a pleasant room temperature and has the heat turned on, while the occupant of the room next door is more comfortable at 68 degrees F and has the air conditioning turned on.

So while the kitchen is ejecting waste heat, some of the hotel rooms are creating new heat for those occupants. Meanwhile next door the air conditioning equipment is injecting cool air into the room and ejecting waste heat into the environment.

All the equipment consumes electricity or perhaps burns natural gas. And the owner of the building is paying for all the costs.

There is a better way: in many cases it is possible to capture some of the "waste" heat from the kitchen ventilation equipment, and more of the "waste" heat from the air conditioning equipment. That heat can then be delivered to storage where it can be used to meet the needs of the occupant who wants a warmer room.

The cost, both in dollars and in energy consumed, to MOVE heat or cold is much, much less than it is to CREATE the heat or cold being used in different places at different times.

Enertopia Corporation can assess the equipment subsystems that run in your building or factory to determine if there are opportunities to capture wasted energy from one subsystem, and use it to benefit another. Every building and factory is unique and so too are our solutions. But generally speaking, if any of your equipment is more than ten years old, then chances are very, very good that you are paying too much for energy that is being wasted.

Methods and Applications
  • Multi-family residential buildings.
  • Shopping centers, commercial buildings.
  • Factories, warehouses, processing and fabrication plants.
  • Mining or Oil & Gas operations.

The methods of recapturing wasted energy are very diverse and can almost limitless applications. For example consider electric motors. Older systems usually used constant-speed electric motors in fixed applications. Ninety percent of all electric motors are AC induction motors, commonly found in air conditioners, industrial machinery, fans and other applications.

But changing to a variable speed electric motor can offer energy savings of 15% - 75%. For larger motors this can be hundreds or thousands of dollars per month in electricity savings. It is possible to recover the entire cost of an advanced new variable speed motor in just six months!

Electric motors generate heat while in operation. It may be possible to capture some of that wasted heat which could extend the useful life of the motor by allowing it to run cooler. The recovered heat might be useful to heat part of the building or in another industrial process, thus lowering costs of heat in that location.

But electric motors are just one of hundreds of different items that need to be reviewed in every serious energy recovery plan. At Enertopia we know that your money is precious to you: so if your limited budget is best spent on replacing an outdated electric motor, we'll tell you that. But if we discover it is more economical to recover waste heat being ejected from your air-conditioning system, and move that heat to a more productive location, we can do that for you too.
