Editor's Notes
- + 6 BREEAM in UK = 41 total
- The common threadWhat does this have to do with O&M of buildings? This will likely be changing someone's behavior: manager, employee, vendor, etc.
- EXAMPLE: Green Cleaning. BIG change for many janitorial services when we started. EXAMPLE: Janitorial Co. and recycling – docked pay when not done correctly.
- LINK for Act 129!
- Go to your building after hours and see what has been left ON. – Night AuditsTypical Office Environment – 50-55 hours occupied vs. 113-118 unoccupied. What’s going on during those unoccupied hoursEducate tenants to turn off / unplug equipmentOcc. Sensors – offices, bathrooms, closets, etc.
- Research has shown that between 50% and 90% of a company’s market value can be attributed to reputation and other intangibles.Studies show that ¼ to 1/3 of a company’s public reputation is based on social and environmental performance.Social responsibility and other sustainability initiatives can have a positive effect on reputation, but a perceived lack of responsibility can have an even more pronounced effect in harming it.(Blackburn)
