Start where the heat affects the operation
Locate hot work areas, the time of day and the activities affected. Identify whether the concern is worker comfort, cooling load or a temperature-sensitive process. Those objectives call for different measurements.
Follow the path through the building
Review the roof build-up and existing insulation, sun-exposed walls, doors and glazing. Check process equipment and ventilation. A hot roof surface is one observation, not a complete explanation of the occupied-area conditions.
Separate cooled and uncooled spaces
In an air-conditioned area, assess the cooling schedule and air leakage as well as the envelope. In an uncooled warehouse, focus on conditions in the occupied area. A cooling-energy reduction from a small conditioned office is not a validated result for an unconditioned production hall.
What the Malaysia pilot taught us
Our roof-only result could not be determined because temperature logging was interrupted. It did not prove that the roof was unimportant. The later combined roof and wall result reinforced the need for continuous baseline and post-work measurement.
Prepare for the first discussion
Share the facility location, hot areas, normal working hours and any available photos or drawings. We will review the likely pathways and explain which information or site checks are needed next.
