Here are a few benefits of our proposed design

Integration into East Village, the new Central Library and City Hall through the District Energy Centre. Citizens and visitors will be able to see green technology at its best and will create intrigue to visiting the facility.

Provides a covering for the upper level of the building, which is intended to be rented for events and generate revenue, making it useable all year round.

Allows filtered light down into the atrium of the existing facility.

Right on the YYC flight path which will become the centre of attention to all YYC visitors.

The Big Idea

The “Big Idea” is to create a solar thermal roof over the new Platform Innovation Centre parkade and enable Calgary to advance its Environment, Social and Governance (ESG) mandate.

Our Technology

What is novel about SolarSteam’s technology is its transformative design for extreme climates. It uses a transparent membrane structure with enclosures that have curved mirrors to concentrate sunlight onto a receiver tube containing pressurized water for heat generation for district heating & cooling, and industrial process heat applications.

Green Building Transformation

Our solar collectors are light-weight and the exterior membrane is ETFE which is  strong and light-weight as well. The roof structure could be made of timber and steel to span large distances, therefore reducing the number of times it connects to the existing structure. The structural loads are proposed to be on the existing interior concrete columns and the two concrete cores. Structural loading will be verified and revised (if required) upon further exploration of the concept. What a person would see from the street level is a floating roof and the solar thermal collectors tracking the sun.

The upper floor would now be covered by a floating mass timber structure. Using this sustainable material will enable the City of Calgary to sequester carbon in the wood fibre using local resources.

Project Location

Located in the heart of Calgary’s historical East Village, the Platform Innovation Centre is an architecturally beautiful structure, with the potential for state-of-the-art SolarSteam system installations.

With ample southern exposure, the opportunity is to mix an eye-catching architectural work of art and inspire Calgarians with SolarSteam’s innovative renewable heat technology that provokes curiosity and vision of a greener future.

District heating

INTEGRATION

As the ENMAX district heating facility is directly to the East of the Platform Innovation Centre, this would be an ideal location of the proposed system.

The shape of the new solar roof will compliment the existing building and will accommodate a large SolarSteam installation.

The heat created will supply the future uses of the new Platform building and will compliment the district heating system in the East Village. The piping to transfer the heat from the rooftop to the ground level is minimal and will run on the south side of the building and then run east towards the district energy facility.

environment

SolarSteam is part of the emerging energy transition in Alberta by achieving Environmental goals that reduce GHGs by 50% compared to fossil fuel powered heat generation.

It is of note that the heat produced by SolarSteam’s system can also be used to heat the existing building, including any new office or residential uses. Using green technologies in assisting future uses helps to tell the story that this building is truly future proof!

While harvesting solar energy is often thought of as only practical in equatorial latitudes, Calgary offers incredible promise for this technology by being the sunniest city in Canada. In addition, the Platform Innovation Centre offers an unprecedented opportunity with an elevated roof, unobstructed southern view and proximity to the ENMAX District Energy Centre.

SolarSteam’s proposed system is projected to produce more than 2 TJ of energy per year with a peak thermal output of 500 kW. This will provide 177 tonnes of CO2 offset otherwise produced by natural gas per year.

social

Integrating SolarSteam’s solution creates Social value by creating high-quality jobs and by establishing Calgary as a global leader in sustainable technology and entrepreneurship.

The upper floor would now be sheltered with a beautiful structure. This upper level is intended to be used as programmable space for events.

Additionally, we could partially enclose this level with folding glazed partitions which would increase revenue, making it useable all year round. Guests will enjoy views to the atrium, SolarSteam’s system, the Central Library and city skyline.

governance

Our fully integrated renewable heat technology represents Calgary’s vision to become a world leader and a global technology development hub in emerging clean technology. Our system will be a showpiece of Calgary’s entrepreneurial spirit, innovation and sustainability not to mention our architectural and engineering expertise. This will be a new architectural landmark to add to Calgary’s beautiful skyline.

The wood soffit ties nicely into the Central Library Design and adds warmth to the existing building.

SolarSteam’s deployment supports the City of Calgary Governance goals such as improving financial performance by as much as 40%, data driven reporting (assisted by Artificial Intelligence & Machine Learning) which is in alignment with global performance standards.
