Occupants’ impact on building energy use continues to increase as building components and systems become more efficient. This source of uncertainty extends well beyond lights and plug loads, often including heating and cooling.

Lighting for humans, not for lumens
In today’s world, the economic engines of modern society run ceaselessly. Globalisation is twisting time zones, internet and satellite communications have virtually eliminated distances pushing economies around the world into a state of perpetual motion. As a consequence, many workers have to adopt the same functional patterns. However, these employees cannot perform like machines constantly over the 24-hour day; rather their productivity, alertness, and mental performance diminishes on the night shift.

Of all the sources of renewable energy available to us, solar energy is arguably the most flexible and least controversial. Solar technology can be deployed at any scale large or small, and can be effective both in rural and urban environments. Although solar panels are often constructed of high embodied energy materials such as steel and glass, the energy they produce over their service life greatly exceeds that required for their manufacture.

2012 SAB Awards Winning Project - Biological Sciences Building University of British Columbia, VancouverThursday, July 26th, 2012
The mandate of the University of British Columbia Renew program is to modernize, rather than replace, out-dated and obsolete buildings. By rehabilitating old structures, substantial reductions in raw materials, energy inputs, and pollutants are achieved – more than any replacement ‘green’ building could accomplish.
Energy Efficiency and Water Self-Sufficiency in remote locations
In the summer of 2011, the Churchill Northern Studies Centre in northern Manitoba, moved into its new 2600m2 facility. The building is designed for 88 visiting scientists and 12 staff working year-round on sub-arctic scientific research and education. The goals for the new facility were to lower utility and operating costs, create a high-performance building that showcases best practice green building engineering design, meet the unique needs of a remote research building in a harsh northern climate, and meet budgetary and time constraints.

Lighting Retrofit of the Social Sciences Centre, University of Western Ontario
Located in London, Ontario, the University of Western Ontario has 239 faculty members, over 6,400 undergraduates and 550 graduate students. The University has 76 buildings – many dating from the 1970s and earlier. As with many older structures, automation or energy control systems were not installed when the buildings were first constructed. As is common at many universities, lights remain on 24/7 all year long. As a result, the cost of lighting classrooms, hallways and common areas can represent as much as 30% of the University’s total utility bill during prime operating periods.
