Preparing for Winter

Preventative HVAC Maintenance Autumn/early winter is an ideal time to perform preventative maintenance on your HVAC systems and switch schedules in your energy management system. Achieve energy savings as high as 25 percent by running clean HVAC equipment versus machines with dirty coils and/or filters (according to a recent ASHRAE study). Justin Lendowski, HVAC  expert …

Recouping your Energy Management System (EMS) Investment: HVAC Type, and Occupancy Sensing

(Part 5 of 5) What factors are used when calculating ROI on a new Energy Management System? When you’re shopping for an energy management system, you want to be presented with a realistic ROI. There are many factors that go into the calculation. Some are weighted more heavily than others. We’ve discussed: electricity prices, natural …

Does Outdoor Temperature Impact Energy Management System (EMS) Payback?

(Part 4 of 5) Energy management systems are an investment but they pay for themselves, typically within 2 – 4 years. EMS providers can calculate your project payback based on specific data. We’ve already talked about  natural gas rates, electricity rates and unitary room controls with central controls. This week we continue the discussion with temperature …

Energy Management System (EMS) Payback: Unitary Room Controls vs Central Building Controls – Or an Integration of the Two?

(Part 3 of 5) Energy Management Systems are—admittedly—a significant financial investment. The good news is they pay for themselves! A typical ROI (return on investment) is 2-4 years. Some EMS providers have continually collected usage data for a decade or more, and are putting that data to valuable use analyzing project payback. We’ve talked about …

Do Electricity Rates Impact Energy Management System (EMS) Payback?

(PART 2 OF 5) In general, electricity thermodynamically is a rather inefficient method of heating or cooling. But its supply is available everywhere, unlike natural gas. However, its rate structure is based upon variable cost constraints on its ability to supply. So the more you use it, the more per kWh it costs. Worse yet, …

Do Natural Gas Rates Impact Energy Management System (EMS) Payback?

(PART 1 OF 5) Energy Management Systems are admittedly a significant financial investment. However, we have good news: they pay for themselves! A typical ROI (return on investment) is 2-4 years. Calculating the amount of time it will take to pay off your investment (project payback projection) is an important function in the EMS purchasing …
