Every type counted. Every U-factor, SHGC, and VT checked against the climate zone. Every egress and tempered call-out flagged. Signed by a senior estimator.
Pulled from real spec books. Every one we now handle, line by line, before the bid leaves your desk.
Estimators count unit types off elevations, then re-derive U-factor, SHGC, VT, and air-infiltration from the spec to confirm each type meets the energy path. One addendum changing climate zone invalidates hours of work.
We read the elevation, the schedule, and the spec in one pass. Every type gets U-factor, SHGC, VT, and AI mapped to its tested assembly. When the addendum drops, the bid re-derives in seconds, not days.
A unit ships whose tested NFRC U-factor or SHGC doesn't meet the prescriptive or COMcheck performance path. Caught at permit or commissioning. Custom units re-order at 10-14 week lead times.
Every type gets cross-referenced against the manufacturer's NFRC 100/200 certificate before the order. Climate zone is auto-applied. If a substitution fails the path, you see it on screen before the BOM ships.
ASCE 7 zone 4/5 corner pressures get tabulated by hand. Corner units sized for field pressure fail mock-up. A single corner window in a high-rise can require a different IGU make-up than the rest of the elevation.
We overlay ASCE 7 zone 4 and 5 onto every elevation. Corner windows get flagged with the design pressure they have to survive. If the spec'd assembly is rated below, the AI proposes a thicker IGU or different lite.
IBC §1030 requires 5.7 SF clear, 24" clear height, 20" clear width, 44" max sill on every habitable room window. One window 18" wide at clear opening fails inspection. Caught at TCO, replaced under the schedule.
We cross-walk every window against the room schedule. Bedrooms, sleeping rooms, basements with habitable use: each one gets clear-opening width, height, area, and sill checked. Fails get a red flag and a suggested unit.
IBC §2406 hazardous locations: glazing within 24" of a door, walking surfaces within 36" of glass below 60", tubs, stair landings. Annealed shows up where tempered is required. Reorder of custom IGUs.
We trace door swings, tub locations, stair landings, and walking surface clearances. Every glass lite within an §2406 zone gets a safety-glazing flag and a matching lite call-out on the schedule.
AAMA 101/I.S.2/A440 rates products by Performance Class and Performance Grade. A C-LC30 spec'd at a CW-PG50 exposure passes paperwork but fails in the field. Sub eats the warranty replacement.
Every unit's AAMA designation is cross-referenced against the elevation it sits on. Building type, floor, exposure category all factor in. Mismatches surface as red flags with the spec section that contradicts.
Scroll the four stages. The matrix updates live: extraction, performance values, climate-zone overlay, pass / fail badges. The same view your senior estimator signs.
5.7 sq ft clear. 24" clear height. 20" clear width. 44" max sill. On every habitable room window, drawn from the floor plan, checked before the BOM ships.
Every window, every elevation, every habitable room. The references the AHJ will check are the ones we check first.
U-factor, SHGC, and VT verified against §5.5 prescriptive limits by climate zone, or rolled into a §11 performance budget.
Window-by-window inputs auto-stage into COMcheck or REScheck. Climate zones 1A through 8.
5.7 SF clear, 24" H, 20" W, 44" sill verified on every habitable-room opening. IRC §R310 cross-walked.
Hazardous-location tempered call-outs at door swings, walking surfaces, tubs, and stair landings.
Zone 4 and 5 corner pressures auto-applied to every elevation. Design pressure rolled into product class.
Every unit cross-referenced to its NFRC CMA certificate. No certificate, no order.
R, LC, CW, AW, HC class verified against building type and exposure. NAFS label readiness checked.
Residential code path verified for habitable rooms, basements, and sleeping rooms with windows.
Zone 4 perimeter and zone 5 corner pressures auto-overlay onto your facade. Corner units get a separate design pressure budget. The AI proposes a thicker IGU or different lite when a unit is rated below the field.
The five things every window estimator asks.
