2015 Virginia Residential Energy Code Resources

On behalf of Viridiant, the Virginia Department of Housing and Community Development and the Southeast Energy Efficiency Alliance, we are pleased to announce the following resources available to aid in the Virginia Residential Energy Code implementation.

Thanks to the support of participating jurisdictions, we worked with urban, rural and suburban localities both large and small across Virginia for diverse participation and to ensure that the voices of Virginia’s communities were heard. Each of their unique perspectives was crucial in compiling information to guide resource development.

The following resources have been identified and/or developed to aid in Residential Energy Code implementation across Virginia:

This document provides an overview of ventilation and filtration best practices with consideration of COVID-19. Submit feedback here.


Insulation & Air Barrier Field Checklist

A checklist intended to help Building Inspectors identify and verify pertinent inspection points covered by the 2015 VAECC as it relates to Insulation and Air Barrier installation and Air Sealing execution. Submit feedback here.


Insulation & Air Barrier Guide

The 2015 VA Residential and Energy Conservation codes give inspectors and plan reviewers the authority to inspect for and assess installation quality and execution. The intent of this document is to provide more context around the authority granted to code enforcement and assist in building the body of knowledge necessary to identify discrepancies on site. Submit feedback here.


Whole-House Fresh Air Ventilation Guide

This document is intended to provide an overview of Whole-house mechanical ventilation requirements incorporated into the 2015 Code Cycle. It covers the various strategies and systems commonly utilized to achieve this code requirement and the pros and cons of each. Submit feedback here.


Slab Edge Insulation Guide

Though the requirements have remained the same since 2009, questions about placement of insulation, depth of insulation, the thermal break between conditioned and unconditioned spaces, and how additions or retrofits to existing homes should be handled remain. The intent of this document is to assist Plans Examiners and Field Inspectors and provide additional information concerning this problematic, and often overlooked detail. Submit feedback here.


Duct Sealing and Testing Guide

Uncontrolled duct leakage is not only an energy penalty, but it also increases infiltration, causes comfort problems for occupants, and can lead to long-term durability concerns for structural components if left unchecked. Virginia’s new requirement of 4% Duct Leakage will be challenging but will have cumulative positive effects across the Commonwealth if effectively enforced. This document is intended to provide focus points and greater context around duct leakage. Submit feedback here.


Suggested Website Layout for Easy Navigating

The website template is meant to serve as jumping off point for a jurisdiction to use when considering updating the structure and content of the building permit section of their website. It is intended to reduce common, repetitive questions that staff receive from permit applicants, while improving the quality of application and plan submissions. A “How to Use” summary can be found here to help navigate the Suggested Website Layout resource. Submit feedback here.
