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.

Don’t Delay If you Don’t Have To!!

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

Improving Indoor Air Quality for Pools

Tuesday, 10 November 2015 by

A client recently approached Efficiency Engineering (EE) to review the HVAC system serving a pool and adjacent community center spaces for an apartment complex. The building has experienced a prolonged period of uncontrollable indoor air conditions and poor air quality in and around the basement pool and adjacent corridors and recreation spaces. The recreation centre

It is now possible to achieve the savings of a condensing boiler without the capital costs! During the past couple of design projects I have performed, a boiler retrofit project in Sarnia and a Social housing building in Toronto, I observed an interesting development.  I was using RBI boilers as a design basis in both
