Net Zero Building Nears Completion in Edmonton

the mosaic centre for conscious community and commerce is nearly ready for occupancy, which could make it the most northerly net-zero structure on the planet.


>” […] The Edmonton centre’s designers and builders are hoping that others can learn from the project that sustainable design doesn’t have to be costly or time consuming – so much so that they have made the contract, calculations and drawings available to anyone.

The City of Edmonton said the Mosaic Centre will be the world’s most northerly commercial building to achieve net zero status, the city’s first designated LEED platinum building, the first in Alberta to be petal certified by the Living Building Challenge and Canada’s first triple bottom line commercial building.

Once completed, the new 30,000 square foot building will include  photovoltaic panels that will cover much of the roof.

It will also have LED lighting designed with a time-clock/daylight controller to meet minimum light levels and a geo-exchange system which will draw heat in winter and coolant in summer.

The 32 bore hole geothermal system reduced the size of the system by 40 kW, saving about $150,000.

It was built 25 per cent ahead of schedule and five per cent under budget.

HKA architect Vedran Skopac, who worked on the project, said it was done to prove to the industry that complex, sustainable buildings can be delivered on time, on budget and without animosity between the parties.

He said the key to this all started with using Integrated Project Delivery (IPD).

The model emphasizes collaboration at an early stage and encourages all the participants to use their talents and insights throughout the different stages for best results.

“It goes all the way down to the end of the line of the tradesmen,” Skopac said.

“We invested so much in designing the process, and training and making everyone a leader.”

Skopac said a major influence on designing the actual structure was creating collision spaces, or places where building residents would be forced to meet and interact.

Skopac also wanted to influence sustainable behavior, like making windows easy to operate and open rather than using air conditioning, and making natural light penetrate deep into the building rather than encourage residents to turn on lights. […]”<

Council plans ambitious geothermal energy facility in Crewe

See on Scoop.itGreen Energy Technologies & Development

PLANS to extract geothermal energy from beneath Crewe are being explored by Cheshire East Council (CEC). The town has been identified as one of only six sites in the UK with the potential to deliver the renewable energy source.

Duane Tilden‘s insight:

>The council point to independent studies that show parts of the borough are sitting on enough natural energy supplies to heat every home in Cheshire East for centuries.

Boreholes 4km deep will be drilled to access 100c hot water beneath the Cheshire Basin. The water could then be extracted and the steam used to drive turbines for electricity generation.

An independent study will now be commissioned to report on both the suitability of the site and how the extraction could take place.<

Go geothermal to maximize energy efficiency

A huge leap in energy conservation, and undoubtedly the most innovative of all energy saving tactics has its origins in the earth itself

Duane Tilden‘s insight:

>This geothermal system provides a quiet environment with a consistent temperature throughout the house or building; efficiently comfortable in the winter, and cool in the summer. The heating or cooling mode can be changed with a simple switch on the indoor thermostat. With virtually no use of fossil fuel, costs for heating and cooling for a typical 4,000-square-foot home can run as low as $2 per day/$60 per month.<
