Heating Crawl Space?

[Designer_82]

16 Unit apartment building with townhouse style apartments.

A section of the basement is full height and another section is crawl space only.

The hvac engineer has provided unit heaters and dehumidifiers in the full height section of the basement but he has also done this for the crawl space.

Any good reason why you would want to heat/dehumidify crawl space?

There is not going to be sprinklers in this crawl space area.

The crawl space has access to soil moisture that may condense when the wet bulb is high outdoors. Wood structure does not like moisture.
If you have now or will have any piping in the crawl space, you will be glad you heated it depending upon outside conditions. In Fla, no: in NY, yes.
It's also nice to have a warm floor over the crawl space in a cold climate.

Depends on... climate, how is the crawls pace built (vapor barriers etc.), and is it vented?
With proper building science you don't need to heat it, but the information given is not sufficient....
