BCIT Seminar Nov 27 with Stefan Storey & James Montgomery SBSP Seminar Nov 28 w/ Sylvia Coleman

A reminder about two seminars next week.


Smart Building Control 2.0: Understanding Occupancy to Find

Reductions in Energy Costs

By Stefan Storey, Ph.D.

Graduate from SBSP (Sustainable Building Science Program), UBC

& James Montgomery, Ph.D. Candidate,

Department of Mechanical Engineering, SBSP Trainee, UBC

Thursday, November 27th from 12-1:30pm

BCIT, NE1-318


James Montgomery and Stefan Storey, co-founders of Sensible Building Science, have

developed a novel methodology to determine actual building occupancy at hourly intervals. This

methodology allows for a comparison of energy use and occupancy to optimize building systems

to only condition spaces that are occupied.

A case study was used to investigate the occupancy-energy relation for key buildings on UBC

campus between Nov. 2013 and June 2014. The results show that building systems generally

condition spaces for significant periods of time when they are unoccupied, even for buildings with

recent BC Hydro Continuous Optimization retrofits. This represents a potential 1-25% savings

when using occupancy to directly control building systems. These savings could potentially

amount to $400,000/yr savings if implemented in all campus buildings.

We also discuss a new ‘Smart Building’ pilot study at UBC where a large library is now being

controlled in real-time by the Sensible Building Science solution, the first institutional building in

Canada to be occupant controlled


Stefan is recent Ph.D. graduate from the Sustainable Building Science Program at

the University of British Columbia. He holds a Master’s degree in Mechanical

Engineering and a Bachelor’s degree in Engineering Physics. Stefan is a specialist

in building science including topics such as building performance evaluation,

occupancy analytics, life cycle costing and environmental analysis. Stefan has

recently co-founded Sensible Building Science, a company specializing in smart

building control, with James Montgomery.


James is a Ph.D. candidate in the Department of Mechanical Engineering at UBC.

He holds a B.A.Sc. in Mechanical Engineering from the University of Waterloo

(2008) and an M.A.Sc. in Mechanical Engineering from The University of British

Columbia (2010). His current research focuses on the impacts of filtration and

ventilation systems on indoor air quality and building energy consumption through

investigating systems at the macro and micro scale. Current projects include the

use of aerosol modelling to determine financial and health implications of filtration

systems in urban environments around the world and a micro scale study of the impact of relative

humidity on filter performance.




The Development of Net-Positive Social Factors at CIRS:

From Pre- to Post-Occupancy Evaluation

By Sylvia Coleman, PhD Candidate, Institute for Resources, Environment and Sustainability

(IRES), Sustainable Building Science Program (SBSP) Trainee, UBC

Friday, Nov 28th, 2014, 1-2pm in BC Hydro Theater, CIRS Building, 2260 West Mall



We know that green and regenerative buildings are designed to perform to certain environmental and

energy standards, but how do they affect the inhabitants inside? Can well-being, health and productivity

be enhanced by a building environment like the Centre for Interactive Research on Sustainability (CIRS)?

Relying on Julia Reckermann’s Pre-Occupancy Evaluation data, provided by inhabitant participants prior

to their move into CIRS and used as a baseline, Sylvia attempted to assess change in several social

factors, by employing a Post-Occupancy Evaluation (POE) survey after the move. The results from the

POE, and from the statistical comparison of pre- and post-occupancy evaluation surveys will be

presented, and feedback invited. The presentation will touch on self-reported well-being, health and

productivity, satisfaction with workspace and building features, engagement with the building’s controls

and communities, expectations, and simple behavior change.


Sylvia Coleman is a doctoral candidate at the University of British Columbia’s Institute for Resources,

Environment and Sustainability (IRES), under the supervision of Dr. John Robinson (IRES) and Dr. Ray

Cole (SALA).

She thinks that “environmental problems” are outcomes of human practices employed to achieve goals of

comfort and convenience, constrained and supported by a context of speed, systemic offerings, and

social norms. Sylvia was previously a sustainability researcher for Busby Perkins + Will, the architectural

firm that designed CIRS. She was also a co-founding partner of Recollective, a green building consulting

firm in Vancouver. In previous lives, Sylvia studied Analytical Biochem and Anthropology. For her Masters

in Advanced Studies in Architecture, she assessed the LEED rating system for socio-cultural values, and

capability for social transformation, and conducted a post-occupancy evaluation of the first LEED Gold

building in Canada (the VITP). In her spare time she dreams of taking the weekend off.
