Energy/Building Automation Systems (BAS)
This department has the campus wide responsibility of monitoring and tracking energy usage and looking for opportunities for equipment or building energy improvements. This department is also responsible for maintaining and upgrading the BAS on campus.

Recommissioning - Recommissioning is the process of improving the operation and maintenance of building systems to meet the owner's operational needs, while using only as much energy as necessary.
Building envelop - The building envelop is the exterior of a building including windows, doors, attics etc. To check the integrity of the building envelope the interior space is placed in a negative pressure and a thermal imaging camera is used to look for infiltration of outside air into the space. (See images below) To check the attics the interior is placed into a positive pressure and thermal images are taken in the attic to look for infiltration from the interior space into the attic.
HVAC/BAS – The building HVAC and the BAS systems are checked to insure that they are functioning at the level they were when the building was commissioned as a new building. Valves, dampers, sensors, transmitters etc. are checked, repaired or replaced and or calibrated.
Engineers are brought in to look at the original design and how the building in presently being operated. Corrections are made to the original design if the building use has changed or if the original design is incorrect.
A Test and Balance company (TAB) is brought in to check air and water flows to insure that the HVAC systems are not wasting energy due to excessive flows and to make any changes that are recommended by the engineers.
The original equipment drawings are amended to reflect the changes the original design.
Riley Hall - Furman is in the process of recommissioning its existing buildings starting with Riley Hall. We have already corrected a number of problems that were discovered and have made some modifications to the mechanical systems thus improving the comfort levels of the staff while using less energy.
Below are some images inside of Riley Hall during the negative pressure test. The test was done 8/9/2010 at 1 pm with an outside air temp. of 90 deg. F.
These are two of the four fans that were used to conduct the building pressurization test.
The images below are taken while the building was in a negative pressure.

Building Automation System (BAS)
Building automation describes the functionality provided by the control system of a building. A building automation system (BAS) is an example of a distributed control system. The control system is a computerized, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems in a building.
BAS core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and device failures and provides email and/or text notifications to building engineering staff. The BAS functionality reduces building energy and maintenance costs when compared to a non-controlled building. A building controlled by a BAS is often referred to as an intelligent building system.
