1 ENERGY STAR Qualified New Homes Thermal Enclosure Checklist & Water Management Checklist Eli Caudill

2 ENERGY STAR Version 3 Tighter Standards Whole Home Approach Better, More Sustainable Construction Surpasses Rapidly ChangingBuilding Codes

3 What Do I Have to Do? Get Trained Get your Rater & Subcontractors on board Learn new requirements for an ENERGY STAR Version 3 Home Get Involved

4 Builder s Role for Version 3 Incorporate V3 changes into design Incorporate ENERGY STAR V3 qualified products Hire qualified subcontractors and Rater Complete Water Management System Checklist

5 Rater s Role for Version 3 Model home from building plans and determine HERS Target Score Perform inspections i and tests of home sufficient i to complete Thermal Enclosure System checklist and HVACSystem QualityInstallationRaterchecklist Prepare and submit proper paperwork

6 HVAC Contractor s Role for Version 3 Design and construct HVAC System in compliance with HVAC System Quality Installation Contractor Checklist Prepare and submit proper paperwork to Rater

7 Insulation Contractor s Role for Version 3 Design and Construct insulation and Air Barrier System in accordance with guidelines on Thermal Enclosure System Rater Checklist

9 ENERGY STAR Version 3: Checklists Checklists To earn the ENERGY STAR label, all homes must now be inspected for compliance with a new set of checklists. Two checklists are to be completed by the Home Energy Rater One checklistby the HVAC contractor One checklist by the builder

10 Implementation Schedule

11 What is ENERGY STAR Qualified new homes built to use 15% less energy than homes built to IRC 2004 Efficienti Safe Durable Healthy Comfortable

12 ENERGY STAR Features Insulation Air Sealing Windows HVAC/Ducts Products

13 Checklists

14 Remember Code supersedes ENERGY STAR requirements Raters must keep electronic or hard copies of completed and signed checklists Plan ahead Make all parties aware of requirements in checklist

15 Thermal Enclosure Checklist (What is it?) Detailed list of requirements for framing, air sealing, insulating new homes High Performance Fenestration ti Quality Installed Insulation Fully Aligned Air Barriers Reduced Thermal Bridging Air Sealing

16 Biggest Changes for Builders Reduced thermal bridging Additional air sealing 6 sided vertical insulation Insulation grading Eave insulation Corner/wall intersection insulation

17 The Checklist Typically two or more inspections Pre drywall inspection Items that cannot be confirmed after drywall installation Up to 8 items can be verified by builder/superintendent All applicable items must be completed

18 High Performance Fenestration (aka goodwindows) (aka good windows) Prescriptive Path Meet or exceed ENERGY STAR program requirements for residential windows g Performance Path Meet or exceed 2009 IECC requirements Table

19

20

21

22 Dry/Humid Climates

23 Quality Installed Insulation Meet or exceed 2009 IECC levels Or Read All insulation installed to RESNET Grade I Or Grade II for surfaces with qualifying i insulated sheathing

24 IECC Table

25 Properly Installed Insulation

26 Fully Aligned Air Barriers

27 Cantilevered Floor

28 Walls behind showers, tubs, fireplace Rigid backing preferred Use cap head nails or similar with flexible air barriers

29 Seal Seams Air barrier not sealed Air Barrier Sealed

30 Kneewalls & Skylights

31

32 Porch Roofs No air barrier Air barrier installed before porch roof

33 Floors Not in contact with subfloor In contact with subfloor

34 Reduced Thermal Bridging

35 Attics Grade I insulation Climate zones 1 5 Min R21 above exterior wall Climate zones 6 8 Min R30 above exterior wall

36 Slabs Entire slab edge insulated to R5 or greater (slab on grade) Depth as required by 2009 IECC 2 Zone 5 4 Zone 6

37 Above Grade Walls Continuous rigid iidinsulation Or Structural insulated panels Or Insulatedconcrete forms Or Double wall framing Or

38 Above Grade Walls continued Advanced d framing including All corners insulated to at least R6 to edge All headers above windows/doors insulated Limited framing at windows & doors Interior/exterior wall intersections insulated to same R value as rest of exterior wall Stud spacing (unless construction documents specify otherwise) 16 OC for 2x4 framing 24 OC for 2x6 framing

39

40 Avoid Excess Framing

41

42

43

44 Headers

45 Air Sealing

46 Air Sealing Solid blocking or flashing and gaps sealed with caulk/foam Cracks fully sealed And other openings

47

48 Intentional Penetrations

49

50 Recessed Lighting in Unconditioned Space ICAT Rated Fully gasketed Above is insulated to R10 if in unconditioned space

51 Sill Plates

52 Top Plates Drywall sealed to top plates at unconditioned attic/wall interfaces Caulk, foam, drywall adhesive, or equivalent material

53

54 Windows & Doors Rough opening sealed with caulk or foam Not tfibrous insulation

55 And Finally Attic Stairs/Panels Durable R10+ Gasketed

56 Water Management Checklist Moisture responsible for a majority of building and material failures Foundation, drainage, flashing details to implement for longerterm durability Filled out by builder

57 Water Management Moisture is introduced d from either inside or outside the structure Control bulk moisture Control capillary moisture it movement Control vapor Ifsomething gets wet, build so it can dry

58 Drain roof Drain walls and penetrations Drain sides Drain ground

59 Inspections Water Managed Site and Foundation Water Managed Wall Assembly Water Managed Roof Assembly Water Managed Building Materials

60 Slabs Sloped Away Patio slabs, porch slabs, walks, and driveways sloped at least in. per ft. away from home to edge of surface or 10 ft, whichever is less

61 Back Fill Sloped Away Back fill has been tamped and final grade sloped at least in per foot away from home for 10 feet or more.

62 Foundation Capillary Breaks Polyethylene sheeting or extruded polystyrene with taped joints beneath slabs Polyethylene sheeting not required in Dry (B) climates

63 Below Grade Walls Exterior Surfaces Poured concrete, concrete masonry, insulated concrete forms Finish with damp proofing coating Wood framed walls finish with polyethylene and adhesive or equivalent

64 Below Grade Walls Class 1 vapor retarders not installed on the interior side of air permeable insulation in exterior ete below grade gade walls

65 Drain Tile Surrounded with clean gravel and fabric filter Footings of basement t& crawlspace walls Sloped to outside grade or sump pump Top of drain pipe below bottom of slab lbor crawlspace floor

66 Water Managed Walls

67 Flashing At Bottom of Exterior Walls Flashing with weep holes for masonry walls Weep screed for stucco cladding systems

68 Drainage Plane Continuous Laps over flashing Bond break for stucco and non structural masonry cladding

69

70 Water Managed Roof Assembly

71 Flashing Step and kick out flashing at all roof wall intersections, extending at least 4 on wall surface above roof deck and integrated with drainage plane above

72 Kick Flashing

73 Valleys & Roof Deck Penetrations Self sealing bituminous membrane or equivalent at valleys & roof deck penetrations (not required in dry climates)

74 Water Managed Building Materials

75 Moisture Resistant Backing Cement tboard or equivalent moistureresistant backing material installed on all walls behind tub and shower enclosures h h d composed of tile or panel assemblies with caulked joints. Photo:

76 And Finally Use Dry Materials Building materials with visible signs of water damage or mold odnot installed

77 Changes in construction Insulation Reduces temperature of wall and roof sheathing

78 Changes in construction Hospitality to mold Tree Lumber Plywood OSB Cardboard Particleboard Paper

79 Why so many moisture problems? Reduced drying gpotential Longer dwell time for water More air conditioning Less water storage capacity Materials that are more sensitive to water

80 Moisture barriers Moisture/vapor retarders 1 perm or less Moisture/vapor barrier Near zero perm rating Aluminum foil = perm rating of 0 Polyethylene sheeting 6.0 mil. = perm rating of 0.06

81 Capillary action Porous materials: wood, concrete Capillary breaks Pore blockers
