Operational reason: Unified occupancy functions § Much of the energy consumed by building systems is to serve the occupants § But sometimes they aren’t there; the need is gone and the service continues § Cutting that waste is a major purpose of building automation § “Comprehensive setback” applies to ventilation, temperature, lights and shading Page 3 Copyright © 2017 All rights reserved.

Ventilation setback in labs Big savings but affects Safety § Application of occupancy sensors to ventilation is sometimes special for labs § In conference rooms and offices, occupancy indicated by schedule AND sensor § In labs it’s operating safely according to an occupancy schedule OR sensor § This approach helps get the safety officer behind the program Page 4 Copyright © 2017 All rights reserved.

Poll the audience § What means have you used to share data between lighting and hvac controls? 1. Common occupancy sensor with multiple sets of contacts 2. BAS gateway reading and writing objects on common network 3. Unified room controller handling complete lighting and hvac function Page 5 Copyright © 2017 All rights reserved.

Special considerations § Requirements for speed in lab air flow control call for special control equipment § Combination of TRA disciplines adds different processing demands Page 9 Copyright © 2017 All rights reserved.

Construction reasons § One automation system instead of 2 or 3 means § Less material § Less labor § Easier construction coordination § Project experience indicates construction savings up to 35% Page 10 35% Less installed cost Copyright © 2017 All rights reserved.

Unified interface panel to engage occupants § A building isn’t Green, if it doesn’t work § If it doesn’t work, for occupants, then it doesn’t work § LEED supports a trend toward increasing control by occupants Page 11 Copyright © 2017 All rights reserved.

Involve occupants in efficiency § Occupants affect energy use § Want to conserve, but don’t know how § Inform them! § Empower them! § Help them participate in sustainability! Page 12 Copyright © 2017 All rights reserved.

Engage occupants: Green Leaf rules for the Room The light rules Setpoint adjustment lighting Lights switched on when there is sufficient daylight The blind rules Winter: Blinds lowered, sunny day and heating Summer: Blinds raised and cooling Page 14 Copyright © 2017 All rights reserved.
