This might be a basic question.
Does the internal temperature of a stack affect the neutral pressure height? Would adding heat into a stack cause the neutral pressure point to rise? Instinctively I think it does, but I cannot find the equation for this.
Appreciate any feedback
Thanks

The natural pressure level (NPL) is roughly mid-height of the building.
What plays a role in NPL deviating from mid-height are mainly the openings in the envelope. Naturally, with more openings at the bottom of the building (entrance, backdoors, garage ramps, loading decks, etc.) the NPL drops down (half-a-floor, or more).
Thanks.
