The Goal… Smarter Design & Control Strategies
Higher Efficiency Primary & Secondary
Systems
On & Off-‐site Renewable Energy Systems
§ UJlizing efficient building systems helps lower overall building W/m2
§ Replacing uJlity power with renewable energy helps lower building W/m2 further
§ IncorporaJng integrated building control strategies helps lower W/m2 even further!
IBT… § Goes beyond controls
§ Defines ‘how’ disparate building energy consuming systems will communicate to one another by creaJng a specific set of repeatable business rules (Example: if this, then that statements)
§ Allows for individual controls of energy consuming systems to communicate with one another seamlessly through hardware & somware
§ Re-‐defines the design process. Design team members can no longer design a project with a goal to merely obtain a permit and construct it. Design team members need to think about how the building will operate long amer the cerJficate of occupancy is received.
§ Is a means to ensure greater energy savings than ever before

Integrated Building Technology Examples
The President of a fortune 500 company schedules an 9:00am meeJng, in the summer, to be held in the conference room and wants to present a power point
Ø The mee;ng is cancelled at the last minute, but the IT department is not no;fied. The lights & projector remain on for the rest of the day. The blinds remained closed. The HVAC system con;nues to cool an unoccupied room. Other employees would like to use the conference room later on in the day, but go elsewhere because they are not sure if there is a mee;ng about to begin in the conference room or not.
Non-‐Integrated Example
• He sends out meeJng invite via Outlook Calendar
• Emails IT department to prepare the room which includes: sesng up & turning on the projector, manually closing the blinds, adjusJng the thermostat to pre-‐cool the room down to prepare for a large group of people, and turning the lights on
The President of a fortune 500 company schedules an 9:00am meeJng, in the summer, to be held in the conference room and wants to present a power point
Integrated Example
• Sends out meeJng invite via Outlook Calendar
Ø The mee;ng is cancelled at the last minute. At 9:10am the room’s occupancy sensor senses no presence & sends a signal to the building’s Energy Management System which automa;cally turns the lights & projector off, the motorized blackout shades open, the hvac system stops cooling and returns to an un-‐occupied set point temperature, and the Outlook integrated touch screen next to the door indicates the room is ‘Open’ and others may use it
• 5 minutes before the meeJng is to begin, the room automates to a pre-‐programmed ‘AV PresentaJon’ preset. The lights go to a preset scene, the projector warms up, the blackout shades close, and the room pre-‐cools itself down to a pre-‐determined set point temperature for an occupied space
On July 21st, the owner of an office building receives an email from the Power Company that he needs to load shed his building by at least 10% to prevent a rolling blackout
Ø The maintenance person physically goes to each tenant on every floor to adjust the thermostat up. He’s not exactly sure how many degrees & and as soon as he leaves the tenants turn the temperature back down. The tenants refuse to turn off any of their lights and they did not install dimming ballasts
• The owner asks the maintenance person to raise the overall temp of the each floor a few degrees
Non-‐Integrated Example
• The owner also asks the maintenance person to turn off 20% of the lights on each floor
Integrated Example On July 21st, the owner of an office building receives an email from the Power Company that he needs to load shed his building by at least 10% to prevent a rolling blackout
Ø An email is broadcast to all building occupants sta;ng that the building has gone into an emergency ‘Demand Response’ mode.
Ø All lights are caped to a pre-‐programmed ‘Demand response’ scene (ex: 75% max light level)
Ø All pre-‐programmed hvac setpoint temperatures are offset a few degrees (ex: cooling temp is raised 2 degrees)
• The owner has the facility manager check the ‘Demand Response’ tab on the building’s Energy Management somware
