Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 67,585.50 MMBtu | 89,349 MMBtu |
| Electricity from on-site renewables | 1,639.60 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 110,918 MMBtu | 155,081 MMBtu |
| Total | 180,143.10 MMBtu | 244,430 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2015 | June 30, 2016 |
| Baseline Year | July 1, 2009 | June 30, 2010 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
Baseline year immediately preceeds insitutional adoption of comprehensive energy conservation program including focus on behavior & operations, installation of solar pv array, and multiple campus retrofit projects. Also preceeds addition of staff positions in engineering and sustainability that have impacted internal cpabilities. The selected baseline allows for measuring progress yielded from these changes.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
Energy policy includes broad university and specific department wide expectations, but also specifies expectations for individual actions, including turning off computers/monitors/printers in work spaces nightly. Regular audits are performed during unoccupied times and notes are left to individuals who have left items on. Since 2012 we have held a student energy conservation contest, and in 2016 added a faculty staff competition. Both create awareness through positive messaging and friendly competition. Energy program staff speak regularly at departmental staff meetings, and student fora ranging from orientation for Residential Advisers to environmental science classes. Energy information and reminders are shared regularly through social and campus media and annual targeted poster campaigns, and an energy conservation "tool box" is available for check out at the main library.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
nightly shutdowns in nearly all buildings (excepting residences) and greater shutdowns during holidays and summer months. All hot water setpoints are adjusted for outside air temperature and all buildings have outside air lockouts for heat. The central chiller is carefully managed to remain off as much as possible. Vacancy and daylight harvesting sensors for lighting are employed in newly renovated/constructed buildings
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Lighting has been renovated to LED in the main campus gym, a the tennis center, the concert hall and main theater, and in all new and replacement outdoor lighting. All lighting in newly renovated dorm and brand new student housing village is LED. Vacancy sensors are standard and ligt harvesting sensors were employed in a recent renovation at the School of Law. Lighting in public spaces in may large buildings is controlled through central EMS and programmed according to the building's daily occupancy. Outdoor lighting is controlled by photocell and regularly audited for malfunction.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
---
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
Since 2011, seven major campus buildings have been retrocomissioned, the central chiller plant has been optimized, a comprehensive campaign to insulate steam pipes campus wide has been launched.
