What does it really take to achieve extreme energy efficiency, and is it cost effective?

Is it possible to achieve extreme energy efficiency across all disciplines and still be a shining example of great design? The renovation of the Ontario Association of Architects’ (OAA) Headquarters building did just that. What did this mean for the lighting design? It needed to honour the existing architecture, create flexible comfortable spaces, and control and leverage the abundance of daylight.

The OAA project (now completed) serves as our case study to help demystify how to effectively incorporate the free light of the sun. We begin with daylight modeling and discuss how it informed the work of other disciplines, as well as the impact on electrical lighting design and control strategy. Finally, we take a detailed look at the financial implications to answer the question: Is it really worth it?

This project illustrates best practices to produce attractive, workable and cost-effective solutions while maintaining the architectural integrity of the building. It has been recognized internationally five times across all facets of light including lighting design, controls, and energy efficiency.

At the end of the seminar, attendees will:
1. Understand the value of daylight modeling and how it informs electrical lighting, lighting controls, and glare control,
2. Recognize the value of the integrated design process,
3. Appreciate the critical value of lighting controls, and
4. Realize the possibility of achieving extreme energy efficiency without compromising aesthetics.

As an added bonus for Ottawa Section, this seminar will be introduced by Toon Dreessen, President of Architects DCA, and OAA past-president.
