Printable Single-Family Residential Field Study Data Collection Form for the 2021 IECC.

This document contains checklists of items to photograph while onsite to help answer questions that may arise regarding the accuracy of entries in the data collection form. Questions may be raised during quality assurance reviews by the project team and PNNL. For each piece of data entered, it is a best practice to have photo-documentation to facilitate future validation of that value. Photographs are also extremely useful for subsequent training programs, field guides, and educational documents.

This PowerPoint is intended to be adapted by project teams to fit their needs and the needs of their stakeholders. The slide theme and other features may be changed to suit the presenting organization.

Field study project teams are required to perform quality assurance (QA) on the data they collect prior to sending it to PNNL for additional QA and analysis. This document provides a list of QA checks that project teams should perform.

Presentation walkthrough of how to fill out the Residential Field Study Data Collection form. 

The primary method for creating a population of homes from which to derive a random sample, as explained in the methodology, is to contact sample jurisdictions to obtain lists of homes. These lists are then sorted randomly to fulfill the sample. While this method has had success, it is not always possible to obtain a list of permits from a jurisdiction. In addition, even when permit data is available directly through a jurisdiction, it can be difficult to ascertain information on the construction status of sample homes. Knowing the phase of construction can be used to inform the timing of site visits to improve data collection efficiency.

For these reasons, alternative or supplemental methods of creating a home population for random sampling may be necessary. Alternative methods that may be used to build a list of recently permitted homes include target searches using jurisdictional inspection schedules, online real estate services, and general internet searches. The same alternative sources of data used to generate the population of homes may also help in scheduling site visits to arrive during phases of construction that maximize the number of observations per site visit.

States, territories, tribal governments, and local governments, with the support of partnering organizations, have a unique opportunity to leverage significant federal funding to support improvements to new and existing buildings in jurisdictions across the country. The Department of Energy (DOE) launched two related grant programs that government entities with the authority to adopt building energy codes, and their partner organizations, can access in support of the adoption, implementation, and enforcement of building energy codes.

These prototypes are used to calculate Building Performance Factors (BPFs) for use with the Performance Rating Method of ASHRAE Standard 90.1-2016 though 2022. These prototypes are used to implement the new approach to calculating BPFs that follow the Appendix G baseline rules and include adjustments to the prototype models made after a specific code has been published. Those BPFs are therefore different than those published in ASHRAE Standard 90.1 2016-2022. This new approach is discussed in more detail in the PNNL Technical Support Document titled, ​Commercial Building Prototypes Based on ANSI/ASHRAE/IES Standard 90.1-2019 Appendix G PRM.
