International Energy Conservation Code – IECC
In Texas, as of November 1, 2016, the 2015 IECC has replaced the 2009 IECC version for commercial buildings and for low-rise residential buildings (three stories or less in height above grade) that cannot be certified using the International Residential Code (IRC), Chapter 11.
Bluegill Energy can help keep you in compliance with the requirements of the IECC. With more than 15 years of experience cutting through the complexity of energy codes, we can help builders like you save time and energy by providing in-depth answers to your questions and concerns.
The IECC contains two sets of provisions for compliance:
- Commercial Provisions
- Residential Provisions
Prior to permitting, each jurisdiction requires the completion of a preliminary design analysis using one of the methods described below to determine if the building complies with the requirements set forth in the code. The jurisdiction also requires a signed report indicating the building has met the requirements. Each building official has the authority to determine who is qualified to perform the analysis and provide the compliance report.
The commercial provisions of the IECC establish minimum regulations for energy-efficient building using one the following preliminary compliance paths:
- Prescriptive – Choice of optionsEnvelope Tradeoff – ASHRAE Standard 90.1-2007/2010 – COMCheck™
- Deemed to Comply Software – COMCheck™
Each compliance path may have mandatory, prescriptive or tradeoff requirements. Mandatory requirements must be met in every building design no matter which compliance path is chosen. Performance testing and commissioning is a mandatory requirement that may require special equipment and trained professionals to complete.
The requirements vary based on the Climate Zone in which the building is constructed. Texas has three Climate Zones (2, 3 and 4), outlined in the map below. Additionally, some cities may have additional requirements beyond those required by the codes.
To meet compliance, various stages of construction require inspections performed by certified professionals, such as:
- Prior to the application of interior wall coverings in order to verify thermal components such as insulation, windows, and air sealing
- At final stages in order to verify lighting and other components
We would be glad to answer all of your commercial IECC compliance questions and provide compliance services in a timely manner.
