A brief description of when and why the building energy consumption baseline was adopted:
---

A brief description of any building temperature standards employed by the institution:

Timers controlling HVAC are in place, and controlled through the Building Air Control system.


A brief description of any light emitting diode (LED) lighting employed by the institution:

Knox College Facilities have been installing and retrofitting campus lighting with more energy-efficient LED lighting. Some of the major areas have included the outdoor campus lighting and the lighting in the T. Fleming Fieldhouse. The newly renovated Alumni Hall has LED lighting as well.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Sensors are present in many areas subject to frequent changes in occupancy.


A brief description of any passive solar heating employed by the institution:

none


A brief description of any ground-source heat pumps employed by the institution:

none


A brief description of any cogeneration technologies employed by the institution:

none


A brief description of any building recommissioning or retrofit program employed by the institution:

In 2006, as part of a 2.5 million dollar energy upgrade, air handling units were recommissioned. This included duct repair and rebalancing units to original building specifications.


A brief description of any energy metering and management systems employed by the institution:

The energy tracking system that the College has is an Excel spread sheet that the Director of Facilities maintains. All utility consumption data is updated monthly. The tracking can be done by building and/or meter for monthly, yearly and multiple years for gas, water and electricity.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

As Knox College replaces appliances, we replace them only with Energy Star appliances. In December of 2013, the college replaced all laundry machines with top-loading energy star washing machines.


A brief description of any energy-efficient landscape design initiatives employed by the institution:

We have implemented an in-house policy that for every mature tree removed, we replace it with two trees.


A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

None at the time. All vending machines are owned by a third party.


A brief description of other energy conservation and efficiency initiatives employed by the institution:

Within the central plant, Knox Facilities monitors and manages control of steam and chilled water, including daily water testing, bi-weekly third party management of chemical treatment, and a service contract to maintain peak performance of the chillers and boilers.
