OpenBuildingControl: Digitizing the control delivery from building energy modeling to specification, implementation and formal verification

Michael Wetter et al.

Summary: The current process of specifying, installing, and commissioning building control sequences is manual and lacks formal quality control, resulting in low performance sequences at scale. To address this, a digitized building control delivery workflow with formal verification and a Control Description Language was introduced to allow customization, testing, and improvement of sequences by mechanical designers. This process has led to a proposed standard, ASHRAE 231P, for digitizing the building control delivery process through a standardized format for exchanging control logic.

Development of a Unified Taxonomy for HVAC System Faults

Yimin Chen et al.

Summary: A unified taxonomy for HVAC faults has been developed, classifying faults based on characteristics and causal relations. The taxonomy uses a physical hierarchy of HVAC equipment and cause-effect relationship model to reveal root causes of faults in HVAC systems, with a structured and standardized vocabulary library to increase data representability and interpretability.
