I have a Customer that has a very open floor plan. 2 story opening in the middle of the house.
When you walk up the stairs you feel a dramatic temperature change when you reach a certain point up the stairs.
What causes this and how can it be corrected ?
Stagnation / inversion layer - common with radiant heated buildings where the heat stays low & it is cooler the higher you go - awesome in commercial & other areas as you aren't heating everything. The reverse can also be in effect also. I talked about it some in http://thehtrc.com/2012/common-sense-radiant-heat-faq
The cause - lack of airflow, bedroom or other doors closed up top which might be conditioned. How do you fix? Use a ceiling fan to stir the air, open doors, windows, etc...
Are these winter conditions, is it colder or warmer upstairs, is it forced air or radiant heat?
It could be a variety of things.
This scenario occurs in the Winter Months. It is warmer upstairs. This is a forced Air System.
Thank you, Kevin
I also should have asked where the furnace was located,basement,1st or 2nd floor. In any case the simplest solution is to close some of the supplies upstairs and make sure they are fully open in the lower levels. The previous homeowner may have adjusted the distribution of conditioned air so it would be cool upstairs in the summer,
