Cheap Ways to Cut Heating Costs
As far as HVAC equipment performance is concerned, cost is a major factor among most entities. When seeking to reduce operational expenses, most technicians look to updating controls, motor replacement and other major improvements. However, there are other low- and no-cost steps that could be taken to trim heating and air conditioning costs.
It's surprisingly common to find entities conditioning unused spaces and areas whose utilization has significantly changed. This is a huge area as far as wastage is concerned. An easy step would be to cut off air flow to such spaces by shutting off fans and doors and closing dampers till normal usage resumes. If usage has changed permanently, then air flow should be adjusted accordingly, especially where the demand for outdoor air isn't significant. To be sure that you are doing this properly, you may want to consult a professional heating and cooling service, such as Schmitt Heating.
This can be done by replacing the fan's pulley wheel with one of a smaller size. This reduces the heat output as well as the load exerted on the fan motor. This would not only slash power consumption, but also reduce the chiller load.
Tasks such as lighting require significant cooling levels. To cut costs, lighting levels should be reduced or controlled to match demand during off-peak hours. This could involve manually turning them off or installing automatic sensors and timers. Turning off lights reduces energy consumption in two areas - the power channeled to the fixture as well as the cooling demand.
Gadgets like vending machines consume power from lights and internal cooling mechanism. Unless there's need to preserve food, the coolers would only be needed to counter heat emission by internal lights. There are some cheap sensors that could shut off such equipment based on demand. Exhaust fans can also be shut off till just before the day starts in order to keep conditioned air inside the building.
Whenever it's possible to control a load that's not needed round the clock, it should be checked accordingly. Otherwise, electric motors left to run continuously contribute to a heat buildup, which results in demand for cooling. Obvious culprits here include escalators, copy machines and ceiling fans. Computer room units should also be shut off or controlled according to demand whenever cooling loads drop.
