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. Energy codes are a subset of building codes, which establish … ASHRAE 90.1 also has a requirement of R-1.9 for supply ducts installed in indirectly conditioned spaces, which includes plenum spaces above ceilings. The most widely used of these standards is ASHRAE 90.1 which outlines standards for constructing energy efficient commercial buildings. Engineers may download Autodesk® Revit® Building Information Modules here. We produce a wide range of foam components for the automotive, athletic, medical and industrial markets. Therefore, where required, the insulation thickness could be 1" or 1-1/2" as listed above. 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. The 2015 version of the IECC significantly increased the requirements for insulation on service hot water pipes compared to previous versions. The table below shows the R-values for Armacell duct insulation. This section of the 2015 IECC/IRC provides details for inspecting to the specific provisions for construction of mechanical system piping insulation and service hot water heating systems, piping design, and insulation and controls where one or more specific types of inspection called for by the IECC or IRC may be necessary to confirm compliance. ASHRAE 90.1 still requires that only recirculation loops be completely insulated and only the first 8 ft from a non-recirculation system be insulated. Please see Armacell TB 38: Exterior Protection of Insulation for more information regarding protecting insulation installed outdoors. 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. The hot water pipes must be insulated according to table C403.2.10; the same table that is used for HVAC piping. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. 2012 IBC Houston Amendments - Print 2(adopted Sep. 1, 2018) 1.2. They meet both the IRC and IECC requirements for Georgia that way and aren’t required to add mechanical ventilation. 101.3 Numbering system. 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. The Houston Amendments to the current adopted codes are listed below. Use this link to access our comprehensive insulation product solution packages. The materials for this course may be used for in-person training purposes. One must simply choose the right thickness to comply with the code requirement for their particular application. The thickness required for low temperature pipes, like refrigerant and chiller water, is less than higher temperature pipes and smaller pipes require less insulation as well.1 In general, refrigerant suction lines and chilled water pipes require either 1/2" or 1" insulation depending on the size and temperature of the pipes. International Mechanical Code 2015 (IMC 2015) Chapter 1 Scope and Administration Chapter 2 Definitions Chapter 3 General Regulations Chapter 4 Ventilation Chapter 5 Exhaust Systems Chapter 6 Duct Systems 601 General 602 Plenums. Fiber-free, flexible elastomeric foam insulation for mechanical systems including: plumbing, refrigeration, HVAC and solar applications. Energy conservation is important to everyone. 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. Mechanic… 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. The 2012/2015 IECC does not specifically require whole-house mechanical ventilation, but it references the ventilation requirements of the 2012/2015 IRC or International Mechanical Code as a mandatory provision. The Armacell Energy division provides a range of industry leading flexible technical insulation and covering systems for industrial energy projects worldwide. Course materials originally published by the DOE Building Energy Codes Program, November 2014. International Energy Conservation Code (IECC), Commercial Mechanical Requirements of the 2015 IECC, Commercial Envelope Requirements of the 2015 IECC, Commercial Lighting Requirements of the 2015 IECC, Residential Requirements of the 2015 International Energy Conservation Code. Therefore, any insulation installed outdoors must have a protective coating or covering to meet energy codes. 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. Armacell pipe insulation products all fall within the thermal conductivity ranges specified in ASHRAE 90.1 and the IECC for the temperature ranges within the limits of the insulation. Building: 1.1. View ArmaFlex tube and sheet installation tips, new product news and more. 4. This is instead addressed in section 604.12 of the International Mechanical Code which requires an approved weatherproof barrier over any duct insulation installed outdoors. The 2015 International Energy Conservation Code® (IECC®) encourages efficiency in envelope design, mechanical systems and lighting systems as well as the use of new materials and techniques. For pipes, section 6.4.4.1.3 in ASHRAE 90.1 and section C403.2.10 in the IECC contain the identical table that shows the insulation thickness required depending on the pipe operating temperature and the size of the pipe.
