Worshop 1

Using ClimateStudio for rapid daylight and energy assessment in early design through a game

Participants will be introduced to a new simulation tool, ClimateStudio, which performs fast
annual illuminance, and energy models combined with an intuitive workflow-based user
interface. As a way of learning, a ‘simulation game’ will be played where participants adjust the
design and features of a prototype green building to optimize environmental performance under
budgetary constraints.


ALSTAN JAKUBIEC| University of Toronto

Alstan is an Assistant Professor at the University of Toronto where he focuses his efforts on the
design of buildings and cities with emphases on human comfort, performance simulation, low-
energy design, and renewable energy strategies. He believes that through data-driven
processes, built environments can be created that support social interaction, require less
energy, and last longer before being razed. Alstan co-creates the popular DIVA and
ClimateStudio tools for calculating the daylighting and energy performance of buildings and
cities and actively develops new software tools as part of his research. He also co-founded
Mapdwell, a technology company dedicated to providing information to homeowners about the
renewable energy potential of their rooftops. Before joining the University of Toronto, Alstan
taught sustainable building and urban design at the Singapore University of Technology and
Design. Alstan holds BA (Georgia Tech) and MA (University of Pennsylvania) degrees in
Architecture, and a PhD in Building Technology from the Massachusetts Institute of Technology.

Workshop 2


COMFEN is a tool designed to support the systematic evaluation of alternative fenestration systems for project-specific commercial building applications. COMFEN provides a simplified user interface that focuses attention on key variables in fenestration design. Under the hood is Energy Plus, a sophisticated analysis engine that dynamically simulates the effects of these key fenestration variables on energy consumption, peak energy demand, and thermal and visual comfort. The results from the Energy Plus simulations are presented in graphical and tabular format within the simplified user interface for comparative fenestration design cases to help users move toward optimal fenestration design choices for their project. 

Intended Audience

Architectural and engineering designers wanting to explore the many options in fenestration design. Fenestration product vendors wanting to compare the benefits of specific fenestration product choices.

 Features of ComFen: 1)Flexible Fenestration Facade Design 2)Comparative Facade Analysis 3) Graphical Display of analysis
