Corners, headers,and rim joists making up the thermal envelope are insulated. � Insulation in floors(including above garage and cantilevered floors)is installed to maintain permanent contact with underside of subfloor decking. Exterior insulation for framed walls is in substantial contact and continuous alignment with the air barrier.Crawl space wall insulation installed in lieu of floor insulation is permanently attached to crawlspace walls. Inspection of log walls is in accordance with the provisions of ICC-400. � Spaces between fenestration jambs and framing and skylights and framing are sealed. Batts in narrow cavities are cut to fit;or narrow cavities are filled with insulation that readily fills the available cavity space. � Exposed earth in unvented crawl spaces is covered with Class I vapor retarder with overlapping joints taped. � Air sealing is installed between the garage and conditioned spaces. � Exterior walls adjacent to showers and tubs are insulated and have air barrier separating the wall from the shower and tubs. � Access openings,drop down stairs or knee wall doors to unconditioned attic spaces are insulated and sealed. � Recessed light fixtures installed in the building thermal envelope are IC rated,airtight labeled at air leakage rate<=2.0 cfm,and sealed to the drywall with gasket or caulk. � Duct shafts,utility penetrations,and flue shafts opening to exterior or unconditioned space are air sealed. � Plumbing and Wiring: Insulation is placed between the exterior of the wall assembly and pipes.Batt insulation is cut and fitted around wiring and plumbing,or for insulation that on installation readily conforms to available space such insulation shall fill all space between wall and piping/wiring. � Air barrier extends behind electrical or communication boxes or,air sealed type boxes are installed. � HVAC register boots that penetrate building thermal envelope are sealed to subfloor or drywall.

Sunrooms: � Sunrooms that are NOT thermally isolated from the building envelope meet the requirements applicable to the building envelope. Materials Identification and Installation: � Materials and equipment are installed in accordance with the manufacturer's installation instructions. � Materials and equipment are identified so that compliance can be determined. � Manufacturer manuals for all installed heating and cooling equipment and service water heating equipment have been provided. � Insulation R-values and glazing U-factors are clearly marked on the building plans or specifications. Duct Insulation: � Supply ducts in attics are insulated to a minimum of R-8.All other ducts in unconditioned spaces or outside the building envelope are insulated to at least R-6. Duct Construction and Testing: � Building framing cavities are not used as ducts or plenums. � All joints and seams of air ducts,air handlers,and filter boxes are substantially airtight by means of tapes,mastics, liquid sealants, gasketing or other approved closure systems.Tapes, mastics,and fasteners are rated UL 181A or UL 181 B and are labeled according to the duct construction.Metal duct connections with equipment and/or fittings are mechanically fastened.Crimp joints for round metal ducts have a contact lap of at least 1 1/2 inches and are fastened with a minimum of three equally spaced sheet-metal screws. Exceptions: Joint and seams covered with air-impermeable spray foam. Where a partially inaccessible duct connection exists,mechanical fasteners can be equally spaced on the exposed portion of the joint so as to prevent a hinge effect. Continuously welded and locking-type longitudinal joints and seams on ducts operating at less than 2 in.w.g.(500 Pa). � All ducts and air handlers are located within conditioned space. Temperature Controls: � Where the primary heating system is a forced air-furnace,at least one programmable thermostat is installed to control the primary heating system and has set-points initialized at 70 degree F for the heating cycle and 78 degree F for the cooling cycle. � Heat pumps having supplementary electric-resistance heat have controls that prevent supplemental heat operation when the compressor can meet the heating load. Heating and Cooling Equipment Sizing: � Equipment is sized in accordance with ACCA Manual S based on building loads calculated in accordance with ACCA Manual J or other approved heating and cooling calculation methodologies. � For systems serving multiple dwelling units documentation has been submitted demonstrating compliance with 2012 IECC Commercial Building Mechanical and/or Service Water Heating(Sections C403 and C404).
