Sustainable Built Environment Performance Assessment (SBEPA) Network

It is in the operation of the built environment — how, when, in which ways buildings, landscapes and infrastructure are used, and by whom — that most affects an environment's performance and sustainability. In fact, for typical standards of construction, the embodied energy is equivalent to only a few years of operating energy. Therefore, a better understanding how buildings and landscapes are actually used is an increasingly important part of more sustainable and resilient design.

The SBEPA Network has recently been established to consider how the university campus can be a ‘living lab’ for testing enhanced approaches to evaluating the broad concept of sustainability in the built environment of U of T and beyond.  Faculty members within four Faculties (Arts and Science including the School of Environment and Computer Science; Applied Science and Engineering; the John H. Daniels Faculty of Architecture Landscape and Design; and the Dalla Lana School of Public Health) along with members of the Facilities and Services team at the University are participating in the Network. The goal of this interdisciplinary Network is to work towards the development of a new standard for the design of sustainable buildings and infrastructure that have mutually supportive and net positive benefits for human wellbeing and environmental performance. The SBEPA Network of faculty members and staff from across the university are working together to address the multi-disciplinary challenge of creating and applying a framework to go beyond the traditional energy use metrics to assess these broader aspects of built environment performance. This framework includes exploration of three performance gaps:

  1. Predicted versus actual resource use (e.g. modelled and measured energy, water consumption);
  2. Expected versus actual lived experience (e.g. Pre- and post-occupancy evaluations);
  3. Measured versus perceived environmental conditions (e.g. thermal comfort measurements and survey results).

The different disciplines involved bring a range of approaches to the complex issues concerning the built environment. The Network considers performance to include building, site, human, and environmental parameters. Highlighting positive co-benefits between, for example, how daylit spaces save on electric energy and also are linked to visitor and employee satisfaction and architectural quality, can be a way to gain support for design initiatives that have up-front cost. Calculating trade-offs and responding to shifting professional and academic roles in building design, construction, and operation are being challenged in sustainable and resilient design, and this cultural shift with this kind of network initiative is important if better performing buildings are to be a reality.
