Self-Correcting HVAC Controls Project Final Report (Free PDF)

File Size: 1.25 Mb

This document represents the final project report for the Self-Correcting Heating, Ventilating and Air-Conditioning (HVAC) Controls Project jointly funded by Bonneville Power Administration (BPA) and the U.S. Department of Energy (DOE) Building Technologies Program (BTP). The project, initiated in October 2008, focused on exploratory initial development of self-correcting controls for selected HVAC components in air handlers. The report, along with the companion report documenting the algorithms developed, Self-Correcting HVAC Controls: Algorithms for Sensors and Dampers in Air-Handling Units (Fernandez et al. 2009), document the work performed and results of this project.

The objective of the project was to develop and laboratory test algorithms that implement selfcorrection capabilities for sensors, economizer dampers, and damper actuators in building airhandling systems. Satisfaction of this objective led to 1) algorithms ready for implementation in or connected to building and equipment control systems for field demonstration and commercial application and 2) underlying methods that may be transferable to creating selfcorrecting capabilities for other heating, ventilating, and air-conditioning (HVAC) system components. Full-scale commercial deployment of this technology will capture significant energy savings by automatically eliminating many of the faults that degrade the efficiency of HVAC systems, thus maintaining energy efficiency well above the efficiency at which these systems routinely operate. Furthermore, to the extent that HVAC electricity use and system peaking are coincident (e.g., in the summer), peak demand will also be reduced by deployment of this technology.
