Heating Plant Boiler Retrofits (Design)

Friday, 22 December 2017 by

The premise of condensing technology is to have low return water temperatures and as the low temperature water passes through the boiler, it reduces the temperature of the flue gas much lower than older non-condensing boilers. As the flue gas temperature drops below 130F, water will begin to condense out of the flue gas. A

As an engineering consulting firm that performs energy audits, our job is to help our clients understand how their building uses energy and steps they can take to improve their energy consumption. It is important to be able to convey our findings to our clients in ways that are accessible for them. We are ultimately

Cap & Trade in Ontario

Monday, 31 July 2017 by

At the beginning of this year, the first compliance period of the Ontario cap and trade program began. The cap and trade program is designed to encourage the reduction of carbon emissions in the province and meet percent reductions of carbon emissions mandated by the Federal Government of Canada. For most, the additional costs of

Traits of a Great Project Manager

Wednesday, 05 July 2017 by

The title “Project Manager” is used frequently across the Engineering disciplines.  Unlike a Professional Engineering licence, the title is an un-regulated one and most anyone can assume the role.  In light of this the Project Management Institute (PMI) aims to set a high standard with its Project Management Professional (PMP) designation.  The requirements are difficult

Global Adjustment In 2005, the Ontario government established a line item on electricity bills called Global Adjustment (GA).  The intent of GA was to account for differences in the Hourly Ontario Energy Price (HOEP) and the contracted electricity rates that the Ontario government pays to third party contracts through Ontario Power Generation (OPG), Independent Electricity

I have recently been involved in a pool dehumidification project to size and select a new dehumidification unit for a pool in the Toronto area. It was a small indoor pool, around 1000 SFT in size, used by tenants for recreational purposes. The Pool house was built above ground with lots of glass walls and

The International Institute for Sustainable Development issued a report quantifying the impact of pollution and climate change on Canadian society.  Highlights are: Urban smog is responsible for 7,712 deaths in 2015. Climate change related heat waves cost an estimated $1.6B in 2015. The cost of extreme weather events from climate change could not be calculated

A refrigeration system is a combination of equipment connected in a closed circuit. A refrigerant is cycled through this circuit absorbing heat in one space and rejecting it to another. Many different compounds are used as refrigerants, but unfortunately many compounds that make excellent refrigerants can be harmful if leaked into an occupied space. As

CHP, or combined heat and power, is an innovative way of reducing the operating costs of your building by generating a portion of your buildings on-site electrical demand and supplementing heat to your primary heating source and domestic hot water systems. Natural gas is burned in an engine to produce electricity and useful heat. CHP
