Save Energy Systems was launched in January 2012 and has grown steadily since. The Demand Limiting Controller, also known as the DLC, is installed in hundreds of locations in over 30 states.
Save Energy Systems was founded by Paul Laskow, president and owner, who sought to remedy an energy consumption issue he was experiencing at his electronics manufacturing facility. After not being able to find a company that offered the solution he was looking for, he created an innovative – and now patented – approach to HVAC controls that allows for the reduction of a facility’s HVAC related energy consumption and demand, reducing a facility’s energy bill by an average of 30%.
As an energy efficiency company, Save Energy Systems is focused on providing small to mid-sized facilities with a level of HVAC control functionality that is equal to, or better than, what is available in large management systems – all for an affordable price and without reducing comfort. Our patented Demand Limiting Controller (DLC) is an innovative system that prevents all of the units from coming on at once while maintaining a comfortable temperature. The result: reduced energy costs for our customers and less impact on the environment.
Our track record speaks for itself…since 2012, we have installed hundreds of systems, saving, in aggregate, millions of kilowatts/kilowatt-hours and achieving a combined savings of millions of dollars for our customers. We are not only saving our customers money but we are also doing our collective part in saving the environment!
What is the patented Demand Limiting Controller (DLC)?
While most businesses are well aware of the costs of energy, many don’t realize how much control they can potentially have over their utility expenses. Electricity, in particular, is often overlooked as a manageable expense.
The Save Energy Systems patented Demand Limiting Controller (DLC) is a cost-saving product designed specifically to reduce demand charges associated with HVAC.
By providing precision temperature control of HVAC systems, our DLC technology ensures Savings, Comfort and Control – all at the same time. It’s perfect for businesses such as health clubs, auto dealers, retailers, offices and distribution/logistics warehouses. By installing the DLC, our customers can take advantage of the same energy-saving techniques employed by big corporations (at a fraction of the price) and efficiently manage the equipment that’s the largest component of their energy bill… the HVAC system.
We have found that the typical installation pays for itself in approximately 18 months and customers save up to 30%, annually, on energy costs, one of their greatest monthly expenditures. Not only do our customers experience measurable benefits to the bottom line but they also greatly help to reduce pollution.
So, How Do We Do It?
The DLC is connected to all thermostats in a facility including zone and supply sensors while communicating via internet with the local weather station for temperature. We constantly monitor what’s occurring in each zone, HVAC unit and outside temperatures.
This next piece is critical – We input the energy use of each component for each roof top unit (or split) into the DLC, including each compressor and evaporator fan. We now have the energy consumption of the HVAC system.
Savings goal – We set the DLC to reduce Demand (the total energy consumed by the HVAC units) by 20%. We call it a goal because on a hot day we’ll let the HVAC systems run without limitations, to provide the highest level of comfort.
Manage to one degree – The DLC manages each zone to within one degree, broken down into tenths.
Actually reduce energy consumption – Before the DLC turns on a rooftop unit to cool or heat it checks to see if there is enough power available under the Demand limit. If so, it turns the unit on. If not, it looks at the temperature in each zone to determine if it within its “comfort zone” (within 1 degree of its set point). If it is, it will then turn off the unit to provide more power under the Demand limit. The DLC will shut off one or more components in one or more units to accommodate turning on the next unit. This process allows for an HVAC unit to be turned on with no net increase in energy consumption resulting in a decrease in Demand and overall energy consumption and saving you money.
