Interval meters are devices that are installed in a building to log and monitor real time energy consumption in intervals of set time increments. These meters are typically found in larger commercial and industrial facilities, most of whom are large consumers of energy. Interval meters are used to determine electricity consumption of the building and

Many of Efficiency Engineering’s clients contact us from time-to-time to comment on the validity of claims from product vendors.  It is our experience that vendors of products with questionable energy conservation claims tend to approach building owners/managers directly instead of approaching engineering firms. Some products that we review very quickly fall into the “not a

Typical cold storage facilities are illuminated by High Intensity Discharge (HID) and/or linear fluorescent fixtures. While these technologies each have their own advantages and disadvantages, LED technology now offers advantages well beyond the upfront energy savings. LED Technology Advantages in Cold Environments: Energy Savings Quality LEDs have greater efficacy than metal halide (MH) technology. This

Green Rating Systems and Certification

Monday, 25 January 2016 by

Sustainable construction and operation of our built environment is key to our planet’s future. While we can argue that any step towards a sustainable environment is a positive one, having rating and certification systems helps guide us to achieving our building goals. There are many sustainable building rating systems available to the North American market.

It is a very common occurrence in the experience of Efficiency Engineering for there to be 1-3 years between a recommendation/design being made and it’s actual implementation. Many of our retrofits cost well into the 6 figures and even 7 from time to time, as such there is an understandable reticence to launch a project.

The Northeast blackout of August 2003 affected over 55 million North Americans, including 10 million in Ontario.  I remember it quite vividly, as it was eerie to walk around the house in complete darkness and silence, and to go outside and see the night sky in all its glory.  I have fond memories of that

With the introduction of energy efficient equipment and lighting technologies in recent years, hydro users everywhere, whether they be commercial, industrial, or residential have been able to shave their utility costs. With the rate of hydro increasing and the cost of technology going there are greater and greater incentives to upgrade aging equipment and lighting

Some of our clients are often surprised when they see the installed cost of a Combined Heat and Power (CHP) plant.  Their point of reference is often the cost of a back-up generator.  The cost difference between the CHP and the backup generators is significant, even when accounting for the extra mechanical, electrical and venting
