None
A brief description of when and why the building energy consumption baseline was adopted:
Emory's fiscal year 2005 was the selected baseline for many sustainability metrics. It was the first year that was considered to have all required data for the measured utility/initiative.
None
A brief description of any building temperature standards employed by the institution:
Emory's temperature policy requires that all building thermostats fall within a range between 68-76 degrees Fahrenheit, and students are encouraged to follow the same guidelines in their dorm rooms. Emory uses the building automation system (BAS) to schedule automatic setbacks on a daily time schedule. During long holidays, buildings and floors of buildings must request to opt out of a building temperature setback lasting the duration of the time the University is closed for the holiday. These programs have dramatically reduced energy consumption and saved the University millions of dollars in utility costs.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
Our Oxford Road Building has the Winona LED cove lights on the fourth floor. There is 400 feet of LAs and 100 feet of LBs. On that project, we are also adding LED in the lowest level of the parking deck. Toki Star ELC linear LED is being used at the round staircase on the outside of the building. A color-changing LED pendant is in the bookstore, and LEDs are in the bookcases in the building's living room.
There are four other buildings/renovations with extensive use of LED fixtures.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Emory has lighting sensors in many of its LEED certified buildings. For example, Emory's Rollins School of Public Health building has occupancy sensors in all areas. Infrared and ultrasonic overhead sensors are our standard. Thirteen other buildings have occupancy sensors, as well.
None
A brief description of any passive solar heating employed by the institution:
None.
None
A brief description of any ground-source heat pumps employed by the institution:
None.
None
A brief description of any cogeneration technologies employed by the institution:
None.
None
A brief description of any building recommissioning or retrofit program employed by the institution:
Emory uses the process of Re-Commissioning (Re-Cx) to bring a facility up to optimal performance to meet its current functional requirements. To date Emory has completed 8 Re-Cx projects and by the Fall of 2014 will have completed 14 projects.
Emory's Sustainable Performance Program (SPP) utilizes the Building Automation System to monitor the buildings HVAC performance and send an alarm when operating conditions exist that lead to unnecessary energy consumption. To date Emory has 5 facilities in the SPP.
None
A brief description of any energy metering and management systems employed by the institution:
We track consumption of steam and chilled water in multiple buildings using our BAS. We have a utility billing system that allows us to track the performance of multiple buildings.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
Emory's procurement procedures are in place so that institutionally-procured equipment is required to be Energy Star certified. This guidance is also incorporated into the Green Office and Green Lab programs to advise individual purchasers. Additionally, the energy efficiency of mechanical systems is a high priority when they are replaced and purchased.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
---
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
Emory has numerous machines equipped with automatic shutdown devices. Some sense a total “lack of use” while others use different technology including motion to trigger the refrigeration shutdown. This cannot be used for items requiring continuous temperature control.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
