The Department of Environmental Engineering requested for their educational program a specific thermohydrometrical conditioned and insulated shelter, where extremely sensitive scientific equipment had to be installed and operated.
It is about a 3.5 meters wide and 4.5 meters long mini shelter construction located in an interior space with one side attached to the wall. The suspended ceiling stands at 3 meters high but the exterior walls of the shelter are rising up to the roof, which has a variable height from 3 to 3.8 meters. Since the internal condition had to be extremely accurate, an anteroom with radar automatic operation of two pairs of sliding doors is placed where the one pair opens for entry while the other is kept closed and vise versa.
The initial drawings presented of the shelter have a wooden structure, which is no longer valid, as a metallic one proved to be more practical for this specific construction.
In particular, the shelter is made of 7.5 centimeters wide division walls with galvanized frames as a structure, insulated boards in both sides, and plasterboard in the suspended ceiling. Pillars (HE) able to endure 180 kilograms were added in the anteroom’s division walls, where the sliding doors are placed.

The equipment of the Environmental Shelter is as follows :
ultramicro balance with weighing accuracy of 0.1 mg
filtration kit
dust sampler
M – LOG, 5 inputs terminal board
power pack for M – LOG
humidity sensor
temperature sensor
relative humidity (record keeping and temperature of humidity sensor)
closed control unit PLENUM
LAB Refrigerator
blood plasma freezer
scale (ultramicro balance) antiseismic marble table
DORMA sliding doors with manual emergency bypass
