The Environment Laboratory is utilized to research comfortable indoor environments, and to develop ways of saving energy. In the experimental rooms, various environments can be created, related to air conditioning, hygienics, fire safety equipment, natural energy and radiation, and many other relevant conditions.

Artificial Climate Experimental Room

Artificial Climate Experimenrtal Room

In the experimental room, artificial outdoor environmental conditions can be recreated by means of temperature control (-30 - 80), humidity, rainfall, snowfall, and sun radiation levels. Heat characteristics and weatherproofing materials can also be tested. Room Dimensions---3.7(L)x3.6(W)x3.4(H)m Temperature--- -30 - +80 Relative Humidity---40 - 95% Special Equipment--- Sunlight 0 - 800kcal/m3h   Rainfall 0 - 100mm/h   Snowfall 0 - 25mm/h

Large Environment Experimental Room

Various scale-model experiments are performed in this room (5m x 8m x 3m). Test pieces can be attached to a partition separating it from the artificial climate experimental room, so that condensation and heat insulation tests can also be performed by controlling temperature and humidity in the two rooms.
Room Dimensions---5.5(L)x8.6(W)x3.4(H)m
Temperature--- -20 - +80
Relative Humidity---40 - 95%
Special Equipment---Test pieces (2.0(L)x2.0(W)x0.2(D)m) can be attached to the partition separating this room and artificial climate experimental room.

HVAC Experimental Room

HVAC Experimental Room

Scale-model experiments and thermal efficiency tests are performed in this room (15m x 10m x 10m). Chilled or hot water can be supplied for experiments. In the HVAC room, scale-model experiments are performed on air conditioning and fire safety systems destined for use in office buildings and large structures such as stadiums and atriums. Room Dimensions---15.0(L)x10.0(W)x10.0(H)m Temperature--- -15 - +35 Relative Humidity---40 - 85% Special Equipment---The facility utilizes equipment for supplying chilled and hot water, and warm and cold air for scale-model experiments.

Clean Rooms

Clean rooms are indispensable in biological, medical and super LSI research and development. Airflow, vibration, noise and static electricity are measured in order to enable engineers to make improvements in the planning and maintenance of these important facilities.
Room Dimensions---6.3(L)x6.4(W)x2.8(H)m
Air purity---CLASS 1 (FED-STD-209D) (Laminar air flow type)
Temperature--- - 22 - +26
Relative Humidity---50%
Static pressure---2mmAq

RI Radiation Room

Hazama is developing radiation protection systems for facilities such as hospitals, and developing new materials through the use of radioisotopes.
Neutron activity---4(GBq)/1.2x10¹⁰ (neutron/decay)
Neutron detector---2"x2"NE-213+256x256[ch]2D-MCA
ray detector---Hp-Ge+4,096[ch]MCA (resolution) 1.9keV/Cs-137
ßray detector---Low background liquid scintillation detector
