Reduce demand charges by clipping consumption spikes

Commercial buildings are typically charged for "demand" which can represent half of the electric bill. Demand charges are dictated by your highest electricity consumption spike in a month. That spike, that one instance, when everything was running can cost you half of your bill. Here is how to clip the spike.

Demand Charges are dictated by your highest electricity consumption spike in a month. To get a better idea of what peak demand is, think of it this way: if you turned on one 40 watt light bulb for an hour, shut it off, then turned on another 40 watt light bulb for an hour, you would have consumed 80 watt-hours of electricity, but since you only had one bulb on at a time, your peak demand would be only 40 watts. If you turn both 40 watt bulbs at the same time and leave them both on for an hour, your energy consumption after an hour would still be 80 watt-hours, but your peak demand would increase to 80 watts. Your usage bill would be the same, but your demand charge would be double.

The same applies for heating and air conditioning (HVAC). If your facility has more than one unit the example of the light bulb applies. 

Though it is certainly not practical to keep only a poriton of the AC units running because it won't be comfortable inside the building, we offer a clever solution to manage the HVAC scheduling that can keep you comfortable while reducing your peak demand

  1. STAGGERING THE HVAC START TIMES - our solution orchestrates when all HVAC units start and will be smart ensuring the starting of the units do not start at once to reduce the spike.
  2. THERMAL MASS - Thermal mass is the ability of a material to absorb and store heat energy. High density materials like concrete, bricks and tiles have high thermal mass. Lightweight materials such as timber have low thermal mass.  Our solution understand the thermal mass of your facility and decides based on temperature forecasts how early to start the AC units. For example, if we anticipate to have 110F during the Sunday service of a church, knowing the thermal mass we can calculate when to start the AC units to achieve a low spike while meeting the desired temperature goal for the service. This means the AC units may start in a staggered manner many hours before the service when ambient temperature is lower.
  3. 24/7 REAL TIME USAGE MONITORING - Our solution is in the cloud connected 24/7 to read forecast for your specific location and reading the facilities consumption to optimize the AC units usage.
