A brief description of when and why the building energy consumption baseline was adopted:
The building energy consumption baseline was adopted as that was directly before the hiring of a full time Energy Management Coordinator.
None
A brief description of any building temperature standards employed by the institution:
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.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
To date, MCC has changed all screw base lamps on the Fort Omaha Campus to LED lighting and are currently working on replacing exterior building lamps as bulbs reach their end of life.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Most classrooms throughout MCC have occupancy sensors, as do a few offices. The buildings that are currently under construction at the Fort Campus will all employ occupancy sensors in classrooms and shared spaces.
None

N/A
None
A brief description of any ground-source heat pumps employed by the institution:
MCC's Sarpy location, which is a shared space with the Sarpy County library is served entirely by ground source heat pumps.
None

None
A brief description of any energy metering and management systems employed by the institution:
MCC's energy management system is moving towards more automated controls whenever possible.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
MCC is cognizant of the energy impacts outdated appliances and equipment can have on our energy usage. To that end, when appliances and equipment reach the end of their useful life we take into consideration the energy impact of updating to high efficiency alternatives both in terms of cost,environmental benefits, and reduction in energy usage.
