Project
The air conditioning design : first and second floor mezzanine and sections .
SPECIAL / UNIQUE PROJECT ELEMENTS The traditional approach to humidity control in industrial applications has been to reduce fresh air input to an absolute minimum and , in many cases , to exclude it entirely . This results in spaces that are difficult to use and to maintain due to airlock and sealing maintenance issues .
It also results in spaces that are designed to run at negative pressures . This is due to the cooling of the air within the space , reducing its volume and creating a vacuum that sucks uncontrolled and unfiltered air into the space . Essentially you cannot exclude fresh air from such a space , it will find its way in anyway , so it ’ s far better to control it , condition it and provide a clean , comfortable and safe environment with excellent air quality for the occupants . In essence , don ’ t make buildings with a poor quality indoor environment . RACA
