IBPSA-USA Denver: Showcase Event

SimClub is excited for its first Showcase Event where building performance practitioners in the Denver area will present their latest work. This event will have two presentation topics:

  • Smart building software platform to enable decision-making with portfolios of buildings
  • Combining high-performance indirect evaporative coolers with heat pumps


People who manage lots of buildings often have limited visibility and control over their building systems or data. This makes it hard to make important business decisions about their portfolio, implement change consistently, or verify operations. A smart building software platform that connects all types of data from all types of buildings, to give visibility into building performance. Unlike a BMS or energy management tool, one central command and control center is provided for an entire portfolio to help make data-driven decisions about their global real estate assets.


High-performance indirect evaporative coolers now have the ability to shoulder significant portions of the air-conditioning load across the western US, bringing powerful enhancements to cooling efficiency and ventilation rates at a time when both are acutely needed. Hybridization with heat pumps allows for dehumidification and heating when needed. This can be accomplished within a packaged unit, or by parallel systems at the building level. Both approaches can be modeled with the ZoneHybrid module in EnergyPlus. Parametric simulations show hybridization can result in annual cooling savings ranging from 33% to 85% over a range of applications while flushing contaminants from the space with 30% to 100% fresh air. These outcomes agree with experience and field results are shared to support the projections.
