This report summarizes technical analysis conducted by Pacific Northwest National Laboratory (PNNL), assessing expected end-use energy consumption in commercial buildings, based on recent editions of the model energy code for the commercial sector, ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. An accompanying spreadsheet is available containing detailed end use data results from the Progress Indicator analysis.
This document attempts to answer the following questions: What is the potential value of increasing compliance with the energy code and which code requirements should be emphasized during these studies? Ultimately, these are the questions that policy makers, funders, and program implementers care about. To answer them, a far more sophisticated approach is needed, one that addresses not only the question of value, but also the resource requirements to determine that value.
This report summarizes technical analysis conducted by Pacific Northwest National Laboratory (PNNL), assessing expected end-use energy consumption in commercial buildings, based on recent editions of the model energy code for the commercial sector, ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings.
This report considers the role of commercial building energy codes in enabling grid-interactive efficient buildings (GEBs). Specifically, it highlights the status of demand flexibility (DF) measures in ASHRAE Standard 90.1. It examines the model code-development process and identifies components preventing the consideration and inclusion of DF measures, including code scope, characterization and analysis of proposed new prescriptive measures, and the time-of-day and geographic differences in their benefits.
This study investigates the technical feasibility of achieving zero energy (ZE) new residential and commercial buildings with national model energy codes. The approach and analysis are intended to provide guidance, inform goal setting, and direct future code development.
