The 2012 and 2015 IECC and other provisions in the International Residential Code (IRC)/International Mechanical Code include air leakage requirements. In both standards, the required insulation thickness is based on the climate zone and where the duct is located. INTRODUCTION Section I. Therefore, where required, the insulation thickness could be 1" or 1-1/2" as listed above. Helpful online resources for successful mechanical insulation applications. Overall, builders will find the 2015 IECC to be a better code than the 2012 version. One must simply choose the right thickness to comply with the code requirement for their particular application. 10/10/2018 2 IECC ‘Envelope’ Compliance - Four Options + One = 5 in Utah PRESCRIPTIVE NEW 2015 ENERGY RATING INDEX (ERI) Mechanical + all Building Energy SIMULATED PERFORMANCE Mechanical Component - U-factor (tradeoffs within individual components) - UA (tradeoffs between components) … Duct insulation requirements are outlined in section 6.4.4.1.2 of ASHRAE 90.1 and in section C403.2.9 of the IECC. The IECC does not differentiate between heating and cooling ducts and the thickness requirements are based on the heating and AC requirements from ASHRAE 90.1. The materials for this course may be used for in-person training purposes. 603 Duct Construction and Installation. 1. The table below shows the R-values for Armacell duct insulation. 2012 IBC Houston Amendments(adopted Feb. 1, 2016) 2. The requirements for insulation on pipes and ducts supporting an HVAC system are outlined in both ASHRAE 90.1 and the IECC. 2021 © Armacell LLC • 55 Vilcom Center Drive • Suite 200  • Chapel Hill, NC 27514 • tel 800 866 5638 • email: info.us@armacell.com. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. Gravity (nonmotorized) dampers shall have an air leakage rate not greater than 20 cfm/ft2 where not less than 24 inches in either dimension and 40 cfm/ft2 where less than 24 inches (610 mm) in either dimension. Therefore, any insulation installed outdoors must have a protective coating or covering to meet energy codes. 2015 IECC - Existing Buildings • C502 Additions shall comply with new construction requirements • C503 Alterations shall comply with new construction requirements with some variations • C504 Repairs not normally required to comply. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. By far, the most widely adopted model energy code is the International Energy Conservation Code (IECC) which uses a significant portion of the energy-saving provisions of ASHRAE 90.1.Over 80% of states have a mandatory energy conservation code and all of these states have used ASHRAE 90.1, the IECC, or a combination of both as a basis for their code. BUILDING ENERGY CODES PROGRAM PNNL-SA-105484 2015 IECC Commercial Scope and Envelope Requirements . The Houston Amendments to the current adopted codes are listed below. Requirements of the outside air dictated by mechanical code not energy code. Structure of the 2015 IECC – Structure of the code – need a slide that shows the different chapters of the code for residential and commercial 3 Table of Contents Residential Provisions Chapter 1 –Scope and Administration. Additional reference material and articles of interest to the specifier or contractor. Between August 12, 2016 and January 1, 2017, the applicant may have selected either version for compliance. The Houston Administrative provisions to the NEC are currently awaiting review by City Council. C405.5 (modification) – exterior lighting. 2015 IECC Commercial: Overview of the HVAC Requirements Howard Wiig, Hawaii State Energy Office Eric Makela, Cadmus. By far, the most widely adopted model energy code is the International Energy Conservation Code (IECC) which uses a significant portion of the energy-saving provisions of ASHRAE 90.1. Whereas previous versions required insulation only on recirculation hot water lines and the first 8 feet of pipe from the water heater in a non-recirculation system, the 2015 IECC requires all service hot water pipes to be insulated from the water heater to the fixture. This is a new requirement for dwelling units that is not in the 2015 IECC, but it is essentially the same requirement as found in Section C403.2.6 of the 2015 IECC for all occupancies. We produce a wide range of foam components for the automotive, athletic, medical and industrial markets. Use this link to access our comprehensive insulation product solution packages. The hot water pipes must be insulated according to table C403.2.10; the same table that is used for HVAC piping. 2015 International Mechanical Code (IMC) 2014 NFPA 70 2015 International Fuel Gas Code (IFGC) 2015 International Energy Conservation Code (IECC) 2015 International Residential Code (IRC) Note 2: The IRC is applicable to the construction of detached one-family and two-family dwellings and townhouses as set out in Section 310. Over 80% of states have a mandatory energy conservation code and all of these states have used ASHRAE 90.1, the IECC, or a combination of both as a basis for their code. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. Since ASHRAE 90.1 is a standard, and not a law, it is not enforceable unless it is adopted by a state or municipality or provisions within it are included in a model code that is adopted. Energy codes are a subset of building codes, which establish baseline requirements and govern building … 2 Hot pipes require anywhere from 1" to 5" of insulation depending on size and temperature. 4. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. Because the City jumped from the 2009 version into the 2015 version, we bypassed the IECC 2012 code where commissioning was first required, and as a result, some members in our community may be seeing commissioning for the first time. However, not every state is inclined to follow the same cycle when it comes to adoption of the IECC. Our foam is used for padding, gaskets, seals and acoustical purposes. As a result, energy conservation standards and codes were developed to ensure energy conservation is a priority for new and existing buildings. Where insulation is required, the thickness must be installed according to table 6.8.3-1; the same table used for HVAC systems and the IECC. Mechanical ventilation shall be provided for dwelling units in accordance with the International Mechanical Code. The 2015 version of the IECC significantly increased the requirements for insulation on service hot water pipes compared to previous versions. If the insulation is not within the range, it can still be used but a thickness must be calculated using a supplied calculation. Therefore, Armacell insulation complies with the standards at the thickness listed in the tables. By Tim Ledden - Armacell Technical Manager-Insulation. BUILDING ENERGY CODES www.energycodes.gov 2 – Energy codes and standards set minimum efficiency requirements for new and renovated buildings, assuring reductions in energy use and emissions over the life of the building.

Start typing to browse our database. To help get a handle on the changes, we have studied the code extensively as well as the City’s take on its requirements, and present our findings below. Electrical: The 2017 National Electrical Code (NEC) became mandatory by state law effective September 15, 2017. The International Code Council (ICC) continues to develop the International Energy Conservation Code (IECC) on a three-year cycle which has culminated in the latest version, the 2015 IECC. In fact, there is almost no difference between these documents when it comes to mechanical insulation for HVAC systems. 2015 INTERNATIONAL MECHANICAL CODE - CHAPTER 4 ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures.
