The EPRA Sustainability Workshop brings together the industry by connecting:
and other key stakeholders committed to creating a sustainable built environment.
This year we are exploring key themes of climate change mitigation opportunities, new technologies and innovation as key elements to shape new business strategies and create value for investors, tenants and communities in which listed property companies operate.
Roxana Isaiu, Director, Real Estate, GRESB will be participating in a panel discussion.

The climate coin toss: Has your business set carbon reduction targets that only have a 50% chance of preventing a catastrophe?
The Science-Based Targets Initiative is helping companies to set carbon targets to achieve the Paris Agreement’s ‘2ºC’ goal, but their approach gives just a 50% chance of success. Can we risk the fate of the planet on a coin toss? [Read more…]
When Algonquin College made a commitment to become a more sustainable institution for future generations, it turned to Siemens to help achieve its goals.
For more than 25 years, Siemens and Algonquin College have partnered to work towards an ambitious goal of ensuring the college reaches a zero net carbon footprint by 2042.
A perfect partnership
As the first Canadian college to sign the Talloires Declaration, which commits post-secondary institutions around the world to be leaders in sustainability, Algonquin College set out to find a provider that could turn its visions of sustainability into a reality. After a strong bid combining solutions from a number of business units, Algonquin College signed on Siemens and its innovative approach.
John Tattersall, Director of Physical Resources Algonquin College:
At Algonquin College, we want to be recognized as global leaders in providing innovative and sustainable learning environments for our students so they can realize their hopes, their dreams, their aspirations. To do that we want a strategic partner that is a global leader. Siemens Canada is that strategic partner. Siemens not only understood the ‘what’ we were after, they clearly understood the ‘why’ we were after it.
Siemens ingenuity powers the campus
Siemens proposal was bold – a Campus Transformation supported by a Strategic Partnership. The scope included Campus-wide lighting and controls, water conservation, major HVAC upgrades, Demand Flow technology, Central Plant improvements, Building Automation and many other building improvements. The transformation also included a 4 MW cogeneration plant, scaled Solar PV, power storage and EV charging stations controlled by a Siemens Microgrid solution. In addition, an on-site Sustainability Coordinator was introduced to support the communication plan and drive non-technical savings through behavior and cultural change.

- Smart Metering
- Substation Automation
- Total Building Solution
A unique energy management system
On top of this extensive renovation, Siemens technology has allowed Algonquin College to create, direct and store its own energy. Siemens microgrid controller sets energy needs from the solar PV and CoGen. They then direct energy to the load, Algonquin College and to energy storage. When needed, the microgrid controller can direct stored energy to Algonquin College.
These improvements have resulted in significant reductions in greenhouse gas emissions from campus buildings, as well as substantial financial benefits. Long term, these will add up to tens of millions of dollars in operating cost savings and reduced deferred maintenance costs. In fact, Algonquin College has seen an annual reduction in costs of $3.2 million, which has been put back into improved classrooms and facilities for its most important stakeholder – its students.

Basin Street Properties Retrofit Seven Rooftop Units with SMC Motors And Saw Total Annualized HVAC Fan Energy Savings of 53%
Basin Street Properties is one of Northern California and Northern Nevada’s prominent developers, investors, and managers of commercial properties with over 4 million square feet under management. The company is committed to sustainable and resilient asset management including energy performance improvement across its portfolio.
Basin Street Properties had a specific goal to optimize HVAC system energy efficiency and make the system intelligent. The ideal HVAC solution would:
- Remotely correlate rooftop unit (RTU) motor data with thermostat data collected by its Building Automation System (BAS)
- Enable it to evolve from scheduled to predictive maintenance operations and dynamic maintenance scheduling
- Feature remote monitoring and fault detection for better service quality so its facilities team could respond to HVAC issues before customers had complaints with how the system was performing
Solution: SMC Smart Motor System (the “LED of Motors”)
SMC Smart Motors feature a patented Switched Reluctance design. Industry results highlight exponential improvements against standard induction motors in performance capabilities including torque, power density, efficiency and versatility. The SMC Smart Motor System combines internet-of-things (IoT) building automation technology to help building operators, facility managers, and certified contractors create intelligent and efficient energy systems. It provides real-time visibility and actionable insights for key components of commercial and industrial buildings. The SMC motor uses electricity only when needed to perform useful work and is less expensive to own and operate than a conventional induction motor.
Implementation: Retrofitting motors
Pilot site: The Lakes, 2255 Challenger Way, Santa Rosa, CA, owned and operated by Basin Street Properties. Building square footage: 20,000
Scope: The pilot project consisted of retrofitting seven RTUs (Manufacturer: Bryant) and replacing existing 1HP fixed-speed induction motors with 1HP SMC Smart Motors
Installation Partner: Mechanical Legacy and Energy Services
Measurement & Verification (M&V) partner: Gridium, Inc.
By replacing induction motors in RTU applications with SMC Smart Motor Systems, Basin Street Properties achieved:
- Total annualized fan energy savings of 53%
- Power draw savings of 30% in Heat/Cool mode (1550 RPM) and 87% in Vent mode (690 RPM)
- Monthly energy savings of 881 kWh when energy use was reduced from 1659 kWh before the project to 778 kWh after
The systems’ remote monitoring capabilities enabled SMC to detect that a motor pulley broke during the pilot and to alert maintenance teams immediately that it needed to be replaced.
- By replacing seven motors in its RTU HVAC system, Basin Street Properties achieved total annualized fan energy savings of 53%.
- The significant energy savings and reduced peak demand shrank the building’s carbon footprint and improved the company’s operations related to sustainability and resiliency.
- The simple motor design and predictive maintenance capabilities made the system more reliable and resilient.
- Equally important for a company that owns and leases office space, Basin Street Properties could better monitor and control comfort levels for the building’s occupants.
One of the benefits of early participation in the GRESB Real Estate Assessment was that it helped real estate portfolios improve their environmental, social and governance (ESG) -related policies and management systems. [Read more…]
