You're referring to the state sanitary code which provides the standards with which an owner must comply. It has nothing to do with the landlord tenant relationship which is a matter of contract and/or landlord-tenant statutes.

Indeed, the code that I am reading doesn't even make allowance for the scenario that the tenant does not want the heat to be at 64 and actually turns the thermostat done or shuts down the radiator.
I suggest you give up thinking about ways to mess with the landlord. Tenants who mess with the landlord and cost the landlord money are subject to eviction, loss of security deposit, lawsuits, and trashed credit.

Beyond that I have no idea what the point of your post is.
