This paper provides a summary of the methods and results of performance testing for a coupled Indoor/Outdoor Environmental Simulator (C-I/O-ES). The simulator consists of an IEQ chamber, a climate chamber, and a replaceable “separation/test wall” assembly. Both chambers have stainless steel interior surfaces and are equipped with independent heating, ventilating, and air-conditioning (HVAC) systems for simulating indoor and outdoor thermal and air quality conditions, respectively. The “separation/test wall” assembly can be used to physically model building envelope assemblies and allows the study of combined air, heat, moisture, and contaminant transport through these assemblies. The simulator can be used to study various emission sources of chemical, particulate, and biological pollutants, space air diffusion systems, air-cleaning technologies, HVAC control systems, building envelope assemblies, and mechanical, natural, or hybrid building ventilation systems and components.
