JEANNE AND PETER LOUGHEED PERFORMING ARTS CENTRE

GREEN GLOBES PROJECT SUMMARY

JEANNE AND PETER LOUGHEED PERFORMING ARTS CENTRE

Green Globes is a program that is licensed for use by BOMA (Building Owners & Managers Association) Canada. It considers itself to be the practical rating system for sustainable building design and it was chosen by the University of Alberta because with Green Globes an owner, designer and contractor can develop a variety of sustainability strategies, maintain budgetary constraints and still receive recognition.

Although LEED is a more recognized certification process for sustainable architecture, using Green Globes as an alternative comes with perks. With Green Globes a building will receive certification if it is registered in the program and uses building practices that contribute to environmental stewardship standards. It is not an all or nothing approach to their certification. It recognizes every effort to achieve sustainability and recognizes that effort. LEED is a very rigorous beneficial program; however, a team may follow all the processes and checklists, if it misses a small portion of the intent, it will not receive all the points and therefore, may not achieve certification

Sustainability has three components to it; environmental, social and economic. Green Globes and all other programs, take those three components into consideration and each program is an effort approach to the continuous improvement of sustainability concepts in our built environment and as such are extremely valuable.

Green Globes provided timely answers to sustainability questions during this project. On past LEED projects BR2 had worked on, there had been challenges to get timely answers to sustainability questions through the design process.

The Jeanne and Peter Lougheed Performing Arts Centre used a Design Build project delivery method because the basic parameters of the project were established and there was a fixed budget to work with. Schick Shiner and Associates, the Theatre Consultant, was called upon for his expertise and to create some of the more innovative aspects for the theatre such as LED lights for the full lighting aspects of the theatre.

It was important to Clark Builders, the General Contractor on the project, that the entire team delivered a quality product and delivered the ‘best bang for the buck’ on this particular project. As a team, we maximized creativity yet had a very clear budget that we needed to follow. The University of Alberta was instrumental in creating opportunities for value by adding features to the theatre such as the 70 ft. photovoltaic tower, the largest building integrated solar voltaic system in Canada. The solar array generates 122 kilowatts of electricity, and any excess electricity produced can be sold back to the grid and help offset the facility’s operating costs. The panels were added to the project thanks to funding from the University of Alberta’s Envision Energy Reduction Program.
