| Baseline period | June 1, 2009 | May 31, 2010 |
A brief description of when and why the energy consumption baseline was adopted:
The baseline year of Fiscal Year 2010 was chosen because of the quality of data available, combined with the historical greenhouse gas calculator estimate of campus emissions. 2010 is one year after the most recent large campus construction of new dormitories in 2009 and precedes the College's solar and LED installations.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls employed by the institution:
Catawba College recommends a temperature range of 68 to 72 degrees for all HVAC systems on campus.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Catawba College has undergone several lighting conversion projects to change most lighting to LEDs. These projects have occurred over a number of years and affect nearly all buildings on campus. The College will be undergoing an assessment of remaining non-LED fixtures with the goal of converting all remaining incandescent and fluorescent fixtures to LEDs.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Beginning in 2000, Catawba College installed geothermal heating and cooling systems for a number of campus buildings. The system now serves twelve campus buildings. The campus also has five buildings with solar thermal systems. Three dormitories, the fieldhouse, and the gymnasium have solar thermal systems for producing hot water. These systems were installed in 2015 as part of a larger project that also added photovoltaic systems to seven buildings and one parking lot on campus. All of these systems are designed to reduce the College's dependence on natural gas-fired boilers on campus and on electricity generated from hydrocarbon fuels off campus.
A brief description of co-generation employed by the institution:
None.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The College's Center for the Environment finished a renovation which was projected to lower the building's energy consumption by approximately 50%. The main changes include new HVAC systems, additional insulation to exterior walls and the roof of the building, and other improvements in the building envelope.
The College is in the process of eliminating gas dryers used across campus, mostly in residence halls.
