The new IECC codes requires lower SHGCs. Does this imply that Optimizer will find for Las Vegas this increases energy use?
I tried your suggestion, however I found the field was not large enough for the detail I needed.
For instance, under air sealing, I want to include the following text:
Reduce air leakage of the building shell inside and outside. Below are minimum requirements, but not limited to:
Air sealing can be done with gun foam, caulk and stucco patch.
• Begin air sealing largest holes and attic bypasses. Seal largest holes first. e.g. gaps around supplies and returns to first floor. Cover large bypasses or soffits with a rigid air barrier (e.g. plywood, OSB, Thermo Ply) foam sealed in place.
• Seal all connections to the attic (highest) from the attic where possible. e.g. recessed cans, supply and return boots, smoke detectors, light fixtures, electrical and plumbing in drywall and top plates, seams in top plates.
• Recessed cans: If non-IC rated, replace with ICAT cans and manufacturer’s listed airtight trims and gasket (if specified). Air seal between drywall and can. If IC/ICAT cans installed, ensure approved air tight trim is installed.
• Seal voids where plumbing pipes penetrate walls. e.g. shower heads, toilets, under sinks, recessed clothes washer and ice box.
• Seal holes in interior finishes, around door frames/jambs, at strike plates, stairs, thermostat(s), medicine cabinets, etc.
• Seal sill plates.
• Seal exterior penetrations. e.g. cable wire, around doors, doorbell, electrical outlets/switches & light fixtures (Leave weep hole at bottom of fixture).
• Weatherstrip exterior doors.I read your response and still need to understand how one models radiant barrier. Weather integrated on the roof sheathing or stapled across the rafters.
