Title: Development of Automated Procedures to Generate Reference Building Models for ASHRAE Standard 90.1 and India’s Building Energy Code and Implementation in OpenStudio

Abstract

This paper describes a software system for automatically generating a reference (baseline) building energy model from the proposed (as-designed) building energy model. This system is built using the OpenStudio Software Development Kit (SDK) and is designed to operate on building energy models in the OpenStudio file format.

  • ASHRAE Standard 90.1-2001 Energy Standard for Buildings except Low-Rise Residential Buildings (hereafter referred to as ASHRAE 90.1-2001 or 90.1-2001) was developed in an effort to set minimum requirements for the energy efficient design and construction of new commercial buildings. The State of Tennessee is considering adopting ASHRAE 90.1-2001 as its commercial building energy code. In an effort to evaluate whether or not this is an appropriate code for the state, the potential benefits and costs of adopting this standard are considered in this report. Both qualitative and quantitative benefits and costs are assessed. Energy and economic impacts are estimated usingmore » the Building Loads Analysis and System Thermodynamics (BLAST) simulations combined with a Life-Cycle Cost (LCC) approach to assess corresponding economic costs and benefits. Tennessee currently has ASHRAE Standard 90A-1980 as the statewide voluntary/recommended commercial energy standard; however, it is up to the local jurisdiction to adopt this code. Because 90A-1980 is the recommended standard, many of the requirements of ASHRAE 90A-1980 were used as a baseline for simulations.« less
  • 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.
  • 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.
  • This report focuses on enhancements to prototype building models used to determine the energy impact of various versions of ANSI/ASHRAE/IES Standard 90.1. Since the last publication of the prototype building models, PNNL has made numerous enhancements to the original prototype models compliant with the 2004, 2007, and 2010 editions of Standard 90.1. Those enhancements are described here and were made for several reasons: (1) to change or improve prototype design assumptions; (2) to improve the simulation accuracy; (3) to improve the simulation infrastructure; and (4) to add additional detail to the models needed to capture certain energy impacts from Standardmore » 90.1 improvements. These enhancements impact simulated prototype energy use, and consequently impact the savings estimated from edition to edition of Standard 90.1.« less
  • Detailed construction data from the McGraw Hill Construction Database was used to develop construction weights by climate zones for use with DOE Benchmark Buildings and for the ASHRAE Standard 90.1-2010 development. These construction weights were applied to energy savings estimates from simulation of the benchmark buildings to establish weighted national energy savings.
