<p>The two-story Flexible Research Platfor (FRP) is located in Oak Ridge, Tennessee. The FRP, with a footprint of 40x40 ft (12x12m), is an unoccupied research appratus that can be used to physically simulate light commercial buildings common in the nation&apos;s existing building stock.</p>
<p><br>The systems in the two-story FRP are multi-zone HVAC systems with 10 thermal zones that can be controlled individually.</p>

<p>This model uses an actual meteorological year (AMY) weather data contatining one year of weather data of Oak Ridge, TN.</p>
