Our current weather is a great reminder of why we choose to live in Arizona. However, our love of the spring air can also lead to higher energy costs, air quality issues relating to allergens, and more frequent visitations from bugs and insects. These things don’t seem to be related, but they are: in order to enjoy the cool air we prop our classroom doors open to allow that air into our classrooms and office spaces.
Please
remember that while it may seem like a good idea to let in some fresh air, it
isn't. As the temperature rises throughout the day, air conditioners will turn
on and in many cases the doors will still remain blocked open. Our HVAC systems
are not designed to handle the additional load of trying to cool (or heat) the
outdoors. The additional load will cause the unit to turn off if they run for
more than one hour and do not reach the thermostat set-point (FYI — it’s 74
degrees during warmer months). As a result, District HVAC technicians will have
to come to the campus and physically reset the unit before it will start again.
With only two HVAC technicians, you may be waiting a while for one of them to
show up. In
addition, your room’s air is filtered as it is drawn into the air conditioning
system, so the open doors cause the filters to clog faster. That results in a
decrease to the air conditioners's electrical efficiency, thus increasing the cost. Filters will also need to be changed more frequently, which also add to the costs.
While
we understand your desire to enjoy these cools mornings while they last,
leaving your classroom (or office) door open is not the best way to do so.
Please help us to stay the course on our energy and cost conservation efforts
by keeping your external classroom and office doors closed. We appreciate all the help and
consideration you can give us.
