Description

Track: Residential Buildings: Standards Guidelines and Codes
Sponsor: 7.6 Building Energy Performance, SSPC 100, SSPC 90.2, Residential Building Committee
Chair: Michael Deru, Ph.D., Member, NREL, Golden, CO
Standard 100-2015 with recent revisions (for existing buildings) and revisions to ASHRAE Standard 90.2-2007 (for new buildings) each include performance compliance requirements for residential buildings that are intended to provide designers, retrofit contractors, and building owners a great amount of flexibility when choosing design alternatives for compliance. However, the two standards use significantly different metrics and methodologies to determine building energy performance. This seminar provides information on the development and application of the performance requirements in these two standards. It also illustrates impacts of the different methodologies as well as examples of performance options and calculations for compliance.

1. Standard 90.2: The Path to Performance
Theresa A. Weston, Ph.D., Member, DuPont Building Innovations, Richmond, VA
The revision of ASHRAE Standard 90.2‐2007 represents a new approach in residential building energy performance. This new Standard 90.2 seeks to deliver residential building energy performance that is at least 50% more efficient than the energy efficiency defined by the 2006 IECC. Key to accomplishing this objective is delivery of an accurate, flexible performance‐based tool to enable user creativity in meeting the performance objectives. This presentation describes the pathway to transform the standard.

2. Standard 100 Residential Applications and Options
Neil P. Leslie, P.E., Member, Gas Technology Institute, Des Plaines, IL
When first hearing about Standard 100, most people think it is a commercial building energy efficiency standard. However, Standard 100 also establishes building energy performance requirements for five different residential building types using climate-dependent target tables derived from the 2009 Residential Energy Consumption Survey database. This presentation summarizes the derivation of these table entries, identify and characterize differences in methodology between Standard 90.2 revisions and Standard 100, and illustrate application of the target tables to real-world homes. Plans for further refinements to the Standard 100 performance calculations are also discussed.
