Temperature Guidelines

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.

Temperature Control Sequence

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.

Scope

Energy conservation is the responsibility of all employees of the College. Practices to be implemented by faculty, staff, and students:

  • Turn off all lighting in unoccupied areas (even for brief periods).
  • Do not prop open doors leading to the outside of buildings. Open doors and windows in the winter can cause freeze-ups in radiators near windows and result in broken water pipes.
  • Do not open windows during the heating season. Note: Open windows and doors send erroneous information to the thermostats causing more occupant discomfort and excess energy use.
  • Report any obvious malfunctions or abuses of energy on the campus to Campus Planning & Sustainability.

Space Heaters

Space heaters are a fire hazard, create hot and cold spots in the building and are being phased out, unless medically necessary.

Space heaters often make the comfort problem worse by tricking thermostats. For example in the winter, if you use a space heater because you are cold, it will make a thermostat register a warmer temperature in that room and therefore not turn on when others need heat down the hall. So a space heater in one room can affect the comfort of many co-workers in your area.

The same affect happens in summer. If you are so cold you need a space heater, there is definitely a problem. If you end up using a space heater, the heater will make the thermostat think its warmer and turn the air conditioner on more, making you colder yet.

Generally, space heaters will only be allowed temporarily if the building’s heating system fails and only until the heating system is functional again.
