HVAC system repair has chilling effect

Feeling a bit chilly in your office lately? MSUM employees have wondered why we’re running the air conditioning in the low 60s during the summer.  The short is answer is that we’re replacing several of our steam pipes which would otherwise bring the temperatures back to normal in our buildings.  Sound silly? It’s a standard and sustainable practice. In order to control humidity and maintain healthy and comfortable levels of indoor air, we must cool the fresh air to the upper 50s to remove the water vapor.  We then reheat that air to the 70s once the humidity has been removed. If you are experiencing discomfort, Physical Plant staff can make specific adjustments in your area. Please submit a work order through the online system which can be found at: https://msumapps.mnstate.edu/authenticate/index.php?applicationid=34

 

Also, some find this practice dubious in terms of sustainability.  It’s actually a best practice for managing indoor air quality and temperature.  Heating, Ventilation, and Air Conditioning (a.k.a. HVAC) is the largest source of energy consumption for most buildings. Note: the air conditioning that we refer to is not only to cool a building, but also to bring in fresh air (i.e. condition air).  Facilities managers and sustainability professionals are constantly working to achieve a balance between energy efficiency and building comfort.  Too much humidity can lead to mold and sickness, too little fresh air can also make people feel ill.  Additionally, certain buildings have strict requirements for indoor climate.  The Center for Arts as well Langseth Hall use more energy than other buildings due to the unique nature of the building’s purpose (think musical instruments, art pieces, laboratory experiments).

The proper industry term is Indoor Environmental Quality, and more information on it can be found here: https://sftool.gov/learn/about/1/indoor-environmental-quality-ieq

Rest assured, our Physical Plant and Sustainability staff are doing the best we can to keep our electric bill and carbon footprint low while maintaining a safe and comfortable work environment.  If you’re interested in learning more about our efforts, please do not hesitate to contact Joe Herbst with the Office of Campus Sustainability.
