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

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.

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

A battery in general is a device which makes electrically charged atoms (ions) travel from one point to another, creating electrical current. It does this by: Having one positively charged electrode (cathode), and one negatively charged electrode (anode) in which the ions travel. In the middle you must have a material for the ions to

Introduction A Detailed Engineering Study for Combined Heat & Power (CHP) was recently completed by Efficiency Engineering at a world class hotel located in Niagara Falls, Ontario. The purpose of the study, funded by the Ontario Government under the Process and Systems Program, was to determine the feasibility of implementing a CHP system in order

Efficiency Engineering recently completed a Combined Heat and Power (CHP) feasibility study under the Process & Systems program offered by the government of Ontario. The purpose of the study was to show the building owner how to conserve energy costs by installing a behind-the-meter CHP system. The study was performed at a 110 unit apartment

The City of Toronto is following the lead of several large North American cities and looking to implement Energy Reporting and Benchmarking (ERB) on commercial and multi-residential buildings. Although details have yet to be finalized, it is expected that: It will start with commercial and multi-residential buildings over 250,000 ft², and eventually make it down

Ontario’s Electricity Production

Where does Ontario’s electricity come from? If you visit the Independent Electricity System Operator’s (IESO) website, you can find out the Ontario’s electricity grid contributors by type, on a day to day basis. Nuclear power plants supply over 50% of our electricity within the province, at all times. This is because nuclear power output does

“Engineers finding methods to make aging buildings more environmentally responsible” Efficiency Engineering was featured in a Toronto Star article on February 28, 2015. Read what our Vice President, Michael Zongor had to say about our recent work with the Oshawa site of Lakeridge Health.

There was an interesting article recently in the New York  Times recently regarding using Algae on Municipal sewage to create diesel fuel, fertilizer and carbon credits.  A Nevada company claims that they can do this cost effectively. The general consensus among climate change scientists and engineers is that there is no single solution that will
