Book excerpt: Building Automation Systems (BAS) are widely used in large commercial buildings to assist in the management of the building HVAC system. The purpose is to replace manual operation with automatic operation, improve indoor air comfort, and to reduce energy consumption through improved control strategies. One reason for lack of energy conservation for BASis that the settings in building automation system are not optimized according to the operation building system condition and load requirements. To address this issue, studies focused on commissioning for BAS, which can be called building re-tuning, have been developed by PNNL to provide optimized solutions for building operators. However, the building re-tuning solutions having been promoted are mainly for the Variable Air Volume system, problems may persist when the BAS for a different type of system needs to be commissioned, for example a Dedicated Outdoor Air System (DOAS). The air handling process for DOAS is very different from the process for a VAV system, despite the fact that DOAS is also widely implemented in commercial buildings.In order to address these issue, this project focuses on the evaluation of effectiveness of the common VAV BAS commissioning measures to the Dedicated Outdoor Air System. The main research method is modeling with the EnergyPlus program. Baseline models with DOAS and fan coil system have been built in this study, and 6 types of commissioning measures are implemented and compared with the base models. The energy performance for the commissioning measures are simulated in 16 different locations in the U.S. Finally, the analysis will be based on the comparison between the effectiveness of measures in different climates, between a VAV system and a DOAS, as well as comparison between DOAS unit and parallel cooling system.This document includes a literature review on commissioning and DOAS, a case study for commissioning a DOAS, and the energy modeling process for this study. The result of modeling and the detailed coding about the commissioning measures are also presented.
