Chiller system optimization: The Hartman Loop in action at Humber

Written by  Robert Colman Thursday, 25 February 2010 01:39

Humber College is one of many educational institutes that are growing substantially right now to meet the needs of students. To meet those needs requires heating and cooling facilities that can handle growth while running at peak efficiency. So when the College had to replace an old 1970s central chiller plant, management looked for a solution that could match that description. This led them to SA Armstrong Limited and the company’s Integrated Plant Control system with Hartman LOOP control technology – one of the most innovative control technologies on the market today. 

Sustainable roofing – consider your options carefully

Written by  Robert Colman Wednesday, 24 February 2010 10:50

Roofs are an important part of the sustainability discussion. Buildings account for about 30 per cent of energy consumed and about 27 per cent of all greenhouse gases created in Canada. Roofs in cities contribute to the urban heat island, which basically makes cities between 2-5 degrees Celsius warmer than surrounding areas, due to a lack of vegetation and soil moisture. When planning a new build or the retrofit of an old roofing system, you can have an impact on this by installing a white, vegetative or high-performance roof. A building owner can offset some greenhouse gases and save energy while adding to a building’s appeal.

Air filtration & energy costs – cutting your unnecessary losses

Written by  Ron Cox Wednesday, 10 February 2010 13:55

One item that comes under scrutiny among facility managers looking to reduce expenses is the HVAC system. It may seem logical to save hundreds or thousands of dollars per year by reducing the frequency of air filter change-outs, or by downgrading to a lower-priced filter. In fact, the small amount of money saved by reducing air filter purchases or by purchasing lower-priced (and lower efficiency) filters pales in comparison to the energy and operating costs saved via robust air filtration maintenance.

2010 to be the year of the smart building app

Written by  Ken Sinclair Wednesday, 10 February 2010 13:39
We just returned from a very successful Air-Conditioning, Heating, Refrigerating Exposition - AHR Expo - in Orlando, and the buzz was all about how powerful cloud-based web services are radically changing building automation industry. Several vendors demonstrated augmented realities with close-coupled web services that provided iPhone-type mind expanding services at lower than before costs.

OPA to the rescue with energy retrofit incentives

Written by  Greg Jones Tuesday, 09 February 2010 16:40
Many thanks to all of you who responded to my question last month about why people won’t invest in energy efficiency with a 50-100 per cent ROI while they still line up for RRSPs returning three per cent. While the comments were interesting, I don’t think we solved the problem.

Are you effectively managing your compressed air? Find the energy savings today.

Written by  Alan Bandes Wednesday, 27 January 2010 13:23
It is amazing that while there is much discussion in various media about energy and carbon reduction, most plant personnel fail to realize that there are incredible opportunities for cutting energy waste and carbon gases right under their proverbial noses. These are opportunities that could dramatically improve their companies’ competitiveness.
Whether a building is labeled “green” or not doesn’t necessarily determine its efficiency level — some buildings are just better managed than others. The challenge in managing any property is to get individuals working within it to operate it properly. This is particularly difficult in restaurants where “efficiency” is all about getting people their food as quickly (and pleasantly) as possible. You can’t turn off a deep fryer with customers at the front of the house just to save energy. Or can you? Leslie Burns, Energy Manager for the Harmony Group of companies is finding there is a lot she can do with the teams at Earls, Joey Restaurants and Cactus Club restaurants to shed energy use without affecting customers.

Lofty ideas require grounding: how to implement a rooftop solar panel deal

Written by  Lisa Borsook and Jeff G. Cowan Tuesday, 26 January 2010 09:59
A number of landlords, owners and tenants have recently received inquiries from rooftop solar panel installers, interested in installing solar panels on their roofs. In principle, the idea sounds good, encouraging green power solutions. But in circumstances in which the owner is not the end user of the building (it has a tenant) or is thinking of selling the building, further consideration may be required before entering into licences for solar panels.

Building automation and the cloud educational series in Orlando

Written by  Ken Sinclair Thursday, 14 January 2010 09:37
I am often asked how one can learn more about the transitions now occurring in our building industry. One way is to travel to a warm location in January, and be part of the World's Largest HVAC&R Event and my 11th consecutive year of providing free education sessions at AHR Expo in Orlando, Florida (www.ahrexpo.com).

Lighting efficiency series: It’s RRSP time… for lighting?

Written by  Greg Jones Wednesday, 13 January 2010 17:27

Well, it’s that time of year again — RRSP season is just around the corner. Every year I leave this to the last minute. The delay is usually due to my procrastination over where to put my money. Where can I get a decent return? My choices are usually pretty limited.

Financial mechanisms to reduce carbon emissions - why they are important

Written by  Peter Rowles Wednesday, 13 January 2010 17:24
The topic of climate change has been hotly debated for the past 20 years. Until recently, scientists, politicians and business leaders, especially in North America, have not been able to agree on the existence of the problem let alone what measures should be taken to mitigate it. It is only recently that consensus levels have dramatically increased. Even the Terminator, Arnold Schwarzenegger, admits that climate change is real when he says: “The facts are there, that we have created... a self-inflicted wound through global warming.” It is now generally accepted that climate change is real, immediate and requires substantive action.
