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

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

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

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

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

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

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

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

Implementation Schedule

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

ENERGY STAR Features Insulation Air Sealing Windows HVAC/Ducts Products

Checklists

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

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

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

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

High Performance Fenestration (aka goodwindows) (aka good windows) Prescriptive Path Meet or exceed ENERGY STAR program requirements for residential windows www.energystar.gov/windows g Performance Path Meet or exceed 2009 IECC requirements Table 402.1.1

Dry/Humid Climates

Quality Installed Insulation Meet or exceed 2009 IECC levels Or Read 2.1.2 All insulation installed to RESNET Grade I Or Grade II for surfaces with qualifying i insulated sheathing

IECC Table 402.1.3

Properly Installed Insulation

Fully Aligned Air Barriers

Cantilevered Floor

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

Seal Seams Air barrier not sealed Air Barrier Sealed

Kneewalls & Skylights

Porch Roofs No air barrier Air barrier installed before porch roof

Floors Not in contact with subfloor In contact with subfloor

Reduced Thermal Bridging

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

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

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

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

Avoid Excess Framing

Headers

Air Sealing

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

Intentional Penetrations

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

Sill Plates

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

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

And Finally Attic Stairs/Panels Durable R10+ Gasketed

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

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

Drain roof Drain walls and penetrations Drain sides Drain ground

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

Slabs Sloped Away Patio slabs, porch slabs, walks, and driveways sloped at least 0.25 025in. per ft. away from home to edge of surface or 10 ft, whichever is less

Back Fill Sloped Away Back fill has been tamped and final grade sloped at least 0.5 05in per foot away from home for 10 feet or more.

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

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

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

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

Water Managed Walls

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

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

Water Managed Roof Assembly

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

Kick Flashing

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

Water Managed Building Materials

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: www.jameshardie.com

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

Changes in construction Insulation Reduces temperature of wall and roof sheathing

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

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

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

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