A Tale of Two Bldgs: In-Depth Performance Comparison + PHIUS Monitoring Protocol

Join us as we explore high level protocols and in-depth performance results of energy and indoor environmental quality measurement within PHIUS+ multi-family buildings. Providing more perspective on actual operation is a key step to transforming the market towards passive design principles.

The presentation team will discuss findings from a ComEd monitoring study conducted by Slipstream which looks at two nearly identical affordable housing multi-family buildings in Chicago: one meeting ENERGY STAR Multifamily requirements and the other achieving PHIUS+ standards. Although we won’t cover all aspects of the comprehensive research-grade undertaking, we will touch on energy, load breakdowns, indoor air quality, and a couple of lessons learned.

Stepping back from the specific study, an overview and key findings of the PHIUS+ Monitoring Protocol will also be presented. The certification requirements of the PHIUS+ program are designed to produce efficient, comfortable, healthy, and durable buildings. But currently those requirements pertain to the design and construction of the building; certification ends as building occupation and operation begins. The purpose of the monitoring protocol is to verify that the desired outcomes are being achieved; to, at least, detect problems in case they are not; and preferably, to diagnose problems as well.
