Methodological Framework for Analysis of GPRA Metrics: Application to FY04 Projects in BT and WIP

Pacific Northwest National Laboratory (PNNL) estimated the fiscal year (FY) 2004 energy, environmental, and financial benefits (i.e., metrics) of the technologies and practices in the U.S. Department of Energys (DOEs) former Office of Building Technology, State and Community Programs (BTS) within the DOEs Office of Energy Efficiency and Renewable Energy (EERE). During the development of the estimates, EERE went through a large-scale reorganization, resulting in the reallocation of the former BTS projects (along with the other former offices) into two new Program Offices: the Office of Building Technologies Program (BT) and the Office of Weatherization and Intergovernmental Program (WIP). The remainder of this document will refer to these projects as BT/WIP for the sake of simplicity. This effort is referred to as GPRA Metrics because it stems from the requirements of the Government Performance and Results Act (GPRA) of 1993, which mandates the reporting of performance goals and measures. The benefits developed for EERE through the GPRA Metrics effort are submitted to EEREs Office of Planning, Budget Formulation, and Analysis (PBFA) as part of EEREs budget request. The GPRA estimates are also used in the formulation of EEREs performance measures. This report includes sections that detail the approach and methodologymorexa0» used to estimate future energy, environmental, and financial benefits produced by technologies and practices supported by BT/WIP in the FY 2004. An overview describes the GPRA process and the models used to estimate savings. The body of the document describes the models used and the diffusion curve estimates. Appendixes contain tables of forecasted benefits for all projects through 2030, along with individual project characterizations and overall results of the FY 2004 GPRA effort.«xa0less

Final Project Report: Self-Correcting Controls for VAV System Faults Filter/Fan/Coil and VAV Box Sections

This report addresses original research by the Pacific Northwest National Laboratory for the California Institute for Energy and Environment on self-correcting controls for variable-air-volume (VAV) heating, ventilating and air-conditioning systems and focuses specifically on air handling and VAV box components of the air side of the system. A complete set of faults for these components was compiled and a fault mode analysis performed to understand the detectable symptoms of the faults and the chain of causation. A set of 26 algorithms was developed to facilitate the automatic correction of these faults in typical commercial VAV systems. These algorithms include training tests that are used during commissioning to develop models of normal system operation, passive diagnostics used to detect the symptoms of faults, proactive diagnostics used to diagnose the cause of a fault, and finally fault correction algorithms. Ten of the twenty six algorithms were implemented in a prototype software package that interfaces with a test bed facility at PNNLs Richland, WA, laboratory. Measurement bias faults were instigated in the supply-air temperature sensor and the supply-air flow meter to test the algorithms developed. The algorithms as implemented in the laboratory software correctly detected, diagnosed and corrected these faults. Finally, an economic and impact assessment was performed for the State of California for deployment of self-correcting controls. Assuming 15% HVAC energy savings and a modeled deployment profile, 3.1-5.8 TBu of energy savings are possible by year 15.

Analysis of Potential Benefits and Costs of Adopting ASHRAE Standard 90.1-1999 as a Commercial Building Energy Code in Michigan

The state of Michigan is considering adpoting ASHRAE 90.1-1999 as its commercial building energy code. In an effort to evaluate whether or not this is an appropraite code for the state, the potential benefits and costs of adopting this standard are considered. Both qualitative and quantitative benefits are assessed. The energy simulation and economic results suggest that adopting ASHRAE 90.1-1999 would provide postitive net benefits to the state relative to the building and design requirements currently in place.

Statewide Savings Projections from the Adoption of Commercial Building Energy Codes in Illinois

ANSI/ASHRAE/IESNA Standard 90.1-1999 Energy Standard for Buildings except Low-Rise Residential Buildings was developed in an effort to set minimum requirements for the energy efficient design and construction of new commercial buildings. A number of jurisdictions in the state of Illinois are considering adopting ASHRAE 90.1-1999 as their commercial building energy code. This report builds on the results of a previous study, Analysis of Potential Benefits and Costs of Adopting ASHRAE Standard 90.1-1999 as a Commercial Building Energy Code in Illinois Jurisdictions, to estimate the total potential impact of adopting ASHRAE 90.1-1999 as a statewide commercial building code in terms of Life-Cycle Cost (LCC) savings, total primary energy savings, and pollution emissions reductions.

Analysis of Potential Benefits and Costs of Adopting ASHRAE Standard 90.1-1999 as a Commercial Building Energy Code in Illinois Jurisdictions

ASHRAE Standard 90.1-1999 was developed in an effort to set minimum requirements for energy efficienty design and construction of new commercial buildings. This report assesses the benefits and costs of adopting this standard as the building energy code in Illinois. Energy and economic impacts are estimated using BLAST combined with a Life-Cycle Cost approach to assess corresponding economic costs and benefits.
