Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 66,919.58 MMBtu | 56,750.94 MMBtu |
| Electricity from on-site renewables | 0 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) | 0 MMBtu | 0 MMBtu |
| Total | 66,919.58 MMBtu | 56,750.94 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2016 | June 30, 2017 |
| Baseline Year | July 1, 2011 | June 30, 2012 |
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):
The building energy consumption baseline was adopted as that was directly before the hiring of a full time Energy Management Coordinator.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 1,109,712 Gross square feet | 901,539 Gross square feet |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.06 MMBtu per square foot | 0.06 MMBtu per square foot |
| Source energy | 0.19 MMBtu per square foot | 0.20 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 5,310 Degree-Days (°F) |
| Cooling degree days | 1,334 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 0 Square feet |

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):
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The goal of Campus Planning & Sustainability, and the College, is to maintain a comfortable temperature for our students, faculty, and staff, but in a reasonable range so the college isn't wasting money on energy dollars over-cooling in the summer or over heating in the winter. To do this, the college has implemented building temperature goals. These are the temperature set points that will be maintained in our buildings, determined by the season and comfort ranges. ASHRAE, an expert in building technology and comfort, has found that 85% of occupants are comfortable within the temperature range below.
Normally Occupied Hours* Winter Summer
7:00am - 10:30pm 68° F +/- 2° 76° F +/- 2°
Unoccupied Hours
10:30pm - 7:00am 55° F +/- 2° 85° F +/- 2°
It is our job as employees to make sure we are dressed appropriately for work and for temperature comfort. While individual comfort preferences can vary, we have used college-wide and building code resources to determine an average comfort level. Therefore, if you tend to be either cool or warm in any season, you can make wardrobe adjustments to ensure comfort in your office area.
Purpose
The purpose of this goal is to create a reasonably comfortable working and learning environment while balancing the need to economize and use our resources wisely. Facilities management is aware of the impact internal temperature variations can have on the comfort and productivity of building occupants. Therefore, guidelines have been
developed to assist in the understanding of our goals for providing the optimum working environment.
The cooling season
Generally from mid-‐April to mid-‐October (depending upon prevailing weather conditions). During Normally Occupied Hours, cooling is provided to maintain indoor temperatures as close to 76⁰F as practical (usually ±2⁰F). During off hours, temperatures may be allowed to either rise above this temperature, or in the case of the hottest periods, drop below this level in order to lower our cooling demand during peak use periods. The target temperature is a balance based on ASHRAE standards (Thermal Environmental Conditions for Human Occupancy) to be comfortable for most people who are dressed appropriately for the season and the desire to be as energy wise and resource efficient as possible.
Heating Season
The heating season is generally from mid‐October to mid‐April (depending upon prevailing weather conditions). During Normally Occupied Hours, heat will be provided to maintain indoor temperatures as close to 68⁰F as practical (usually ±2⁰F). During off hours, temperatures may be allowed to drop as low as 55⁰F. This is consistent with ASHRAE standards (Thermal Environmental Conditions for Human Occupancy) to be comfortable for most people who are dressed appropriately for the season.
