The PCU Centre proposed to be built on the fairgrounds at Island Park in Portage la Prairie is a little short of the type of green it takes to construct such a project. However, once the recreation complex is completed, the building will definitely not be short on the kind of green it takes to be environmentally friendly.
That’s because the designers of the building have made sure to include enough environmentally sustainable features the project has been able to be registered as a Leadership in Energy and Environmental and Design (LEED) Silver-rated project.
“Right from the start, this was to be a LEED Silver building; that was a given,” explained Guenter Schaub, project manager for the multiplex and principal structural engineer at Tower Engineering. “And we were happy that it was because that means it’s a sustainable building.”
The LEED green building rating system was originally started by the U.S. Green Building Council in 1998, and was adopted by the Canada Green Building Council (CaGBC) in 2003.
According to the CaGBC website, buildings in Canada currently contribute as much as 35 per cent of the country’s overall greenhouse gas emissions. Their goal is to reduce the percentage of emissions in Canada to zero by 2030, by using the LEED program to make sure new buildings, such as the PCU Centre, are built more efficiently and use less energy, create less waste and conserve water.
“LEED looks at energy efficiency and sustainability, and it’s not just heating and insulation, although that is a big part of it,” explained Schaub. “It looks at a lot of things, like whether the site you’re building on has been built on before, or whether it’s raw land that you’re plowing up. It looks at what you’re doing with rain water: are you storing it on site and making use of it or are you just dumping it into the municipal system?; and where your building materials are coming from: are they coming from close by or are they coming from miles and miles away?”
The CaGBC LEED program uses five principal categories when deciding how green a building is and whether it will be given a silver, gold or platinum rating. The five categories are site sustainability, water efficiency, energy and atmosphere, materials and resource and indoor environmental quality.
Each category has a number of points associated with it, and the more goals a project hits, the more points it receives, giving it a higher rating.
Out of a possible 70 points, the PCU Centre had to hit between 33 and 38 points to receive the silver certification.
“Green building is really a tool to help communities to achieve their sustainability objectives,” said Rodney McDonald, chairman of CaGBC’s Manitoba chapter. “We’d like to congratulate the RM of Portage and the City of Portage for registering the project with the CaGBC, and pursuing a LEED certification; it shows real leadership for the community.”
To be able to register the project as LEED Silver, designers of the PCU Centre incorporated a number of environmentally sound ideas into the construction. For example, the building will use excess heat produced by the artificial ice plant, which keeps the two ice surfaces cold, to help heat both the building and pool water.
Also, water runoff from the parking lots and building surfaces will be naturally filtered and stored in a retention pond located on the fairground property before it is sent back to the lake. The pond will be aerated by three windmills, and the process is designed to remove foreign matter from the water, as well as provide a nice spot for people to sit around the multiplex.
“Basically, we’re making sure that we will not be putting anything into the ground that we shouldn’t,” explained Coun. Jeff Bereza, chairman of the city’s planning and economic development committee. “All the water will be pretreated before it goes into a water body like Crescent Lake.”
A number of smaller things will also help the building be as green as possible, such as using natural light instead of standard lighting wherever possible and using recycled materials in the concrete.
Not only will the LEED Silver designation aid the environment, it will also save some of the money needed to build the project.
The federal and provincial governments have each promised to give the project $3.3 million in public funding, but both levels of government would not have offered the money if the PCU Centre had not achieved at least a LEED Silver rating.
Portage Mayor Ken Brennan said although the provincial and federal funding played a role in the decision to reach the LEED Silver rating, he said there were other factors in the decision process as well.
“We wanted to build a building that makes sense as far as the environment is concerned, as far as energy consumption is concerned, and as far as operating costs are concerned,” he said. ‘The fact that it’s somewhere between a LEED Silver and LEED Gold rating means that it is a highly energy-efficient, green-type building, and that is just the right thing to do in this day and age.”
Brennan said some of the environmental choices made by the designers will also save the city money in running the facility, once it is operational. He pointed to the plan to use the heat from the ice plant to heat the building as a prime example of why the LEED Silver rating is good for both the environment and the city’s pocketbook as well.
“That is a huge cost saving to the city as far as operational costs down the road, and it’s also good for the environment,” explained the mayor. “We’re not using a lot of energy that we needn’t use, and we’re not blasting a lot of hydrocarbons by burning gas.”
At a public meeting held on May 15, the city announced the multiplex, which was originally estimated to cost no more than $38 million was actually going to come in at $42 million, and as a result, the project has been put on hold while costs are shaved.
The cost-saving measures taken to bring the price tag on the PCU Centre down to a workable amount will not affect the environmental aspects included in the original plan, according to Brennan.
“That’s something that we can’t change with the cost because it’s part of the criteria for the federal and provincial money,” he said. “I don’t think that we’d want to anyway because it’s important that we build that type of green building in our community.”
Bereza pointed out the PCU Centre is not only planned for people presently living in Portage and in the area, but as something people will be able to use and be proud of for a long time. He said spending a little more money right now to make sure the building is environmentally sustainable will make sure the sports complex will be around for a long time into the future.
“I think that when we looked at building the multiplex, we looked at building something for generations to come,” said Bereza about the project. “To be as environmentally responsible as possible and to make a project that is very energy efficient and is very ecologically efficient was incredibly important to us.”
