Savings by Design (SBD) – Part 3 BuildingsEnergy Modelling Guide – 2020

The Enbridge Savings by Design (SBD) program as delivered by Sustainable Buildings Canada (SBC)
includes an integrated design process (IDP) component to help builders improve energy and
environmental performance in their new construction projects. The program is offered to commercial,
multi-unit residential and affordable housing projects falling under Part 3 of the OBC. The program may
also be applied for Part 10/11 or similar major retrofit programs as determined by Enbridge. Enbridge
offers the SBD program under 2 separate initiatives – SBD Commercial (SBD-Comm) and SBD Affordable
Housing (SBD-AH) where the primary distinction is the nature of the incentives provided to the
proponent. The energy modelling requirements are the same for each.
For the SBD-Comm program, qualifying projects must be located within the Enbridge service area, are
required to have a minimum floor area of 50,000 ft², must comply with Ontario Building Code (OBC)
Supplementary Standard SB-10, and be intended for commercial, institutional, industrial or multi-family
residential occupancy. Note that Enbridge will make exceptions to the 50,000 ft2 requirement on a case
by case basis. Projects are further required to use natural gas in the final design. The SBD-AH program
does not have a minimum size requirement but does require the use of natural gas in the final design.
The program includes a 1-day design workshop where builder teams and subject matter experts (SMEs)
collaborate on ways to improve the energy and environmental performance of the proposed building.
Energy modelling is used to demonstrate and estimate the energy performance potential for various
design and equipment improvements. Follow-on incentive funding is available for projects designed
and built to meet an annual energy performance level consistent with the requirements of the SBD-
Comm and SBD-AH programs.1 Details on those incentives can be found here:

Natalia Ortiz Moreno

Natalia Ortiz, student of Project Management Environmental (PME) program in Seneca Polytechnic, has an Environmental Engineering background completed at Universidad El Bosque in Colombia. She has always been involved in sustainability roles and projects that included Environmental Management Systems implementation, Water Treatment Systems’ design and operation, Hazardous and Conventional Waste management and minimization practices, as well as Ecosystem’s Conservation and Energy
Efficiency programs.

For the PME – Applied Project Management Course, Natalia developed a Green Roof Assessment Tool for Seneca Polytechnic’s Office of Sustainability, with the aim to provide green roof technology recommendations best suited to a particular scenario, taking into consideration multiple aspects of green roofs and buildings; infrastructure, design, materials, environmental factors, and costs, as well as the Toronto Municipal Code – Green Roof bylaw. Natalia also has a scientific journal publication as the main author of the project “Selection and sizing of industrial wastewater treatment units required at the
new maintenance, repair, and overhaul (MRO) aircraft facility owned by Avianca S.A. in Rionegro Antioquia” in the El Bosque University Journal of Technology.

Natalia strongly believes there are several research topics left to be developed, and the importance of
working towards Sustainability from different backgrounds, knowledge, and cultures to build strong, productive, and resilient communities.
With the vision of growing cities and infrastructure along with nature, always preserving and respecting the ecosystems’ attributes and services, Natalia would like to keep researching and acquiring more experience in Sustainability roles.



Emily Smit

Emily is a second-year PhD student in Geography at the University of Toronto, and a co-operator of a small home renovation company, Magnus Home Improvements. Her research seeks to determine how single-family homes can quickly and best be retrofit to achieve Toronto’s emissions reductions targets – including net-zero by 2040 – as part of the TransformTO climate action plan. Specifically, she will assess the impact of municipal home energy reporting and disclosure programs, as well as produce recommendations for growing the retrofit labour force in ways that attend to the UN Sustainable Development Goals. Further, her research seeks to understand how home retrofit activities can be regenerative and produce net-positive impacts for humans and the environment towards transformative, place-based sustainability. When not at her computer, Emily can be found cycling with her kids to and from school or making funky sounds on her analog synthesizer.

Bofa Udisi

Bofa is a sustainability professional with over seven years in the energy and environment industry. He has a Bachelor of Science in Energy and Petroleum Studies from Novena University in Nigeria and graduate certificates in Energy Management and Environmental Project Management from Seneca College in Toronto. In 2020, he graduated from the University of Waterloo with a Master of Environment and Business degree. He is currently a Ph.D. Candidate in the Building Science program at Toronto Metropolitan University, researching whole-life carbon reduction in new construction and building renovations.

Bofa‘s work experience is primarily in the built environment, working in the private and public sectors in roles that involve structural and environmental assessment of building structures, HVAC engineering design and sales, and facilities management. Bofa is a member of several industry associations, such as the Association of Energy Engineers (AEE), the American Society for Heating Refrigeration and Air Conditioning Engineers (ASHRAE), and the Project Management Institute (PMI). SBC’s bursary will go a long way in supporting Bofa‘s research and his desire to learn.
