Single-sash spruce windows with triple insulating glazing, factory gate

1. Scope and Applicability

This method is restricted to manually operated single-sash spruce windows for vertical wall openings, factory delivered with installed triple-pane argon insulating glazing, hardware, seals and actual coatings. Foreground starts from purchased kiln-dried laminated window scantlings and sealed insulating glazing assemblies; it includes machining, corner-joint bonding, finishing, assembly, acceptance and packaging. The electric foreground route excludes on-site drying, wood lamination, IGU fabrication and combustion boilers.

Excluded products are bare frames, unglazed sashes, French windows, multiple-sash windows, roof windows, aluminium-clad timber windows, other species routes and products requiring special fire/smoke performance. Frame stock, glazing assembly and accepted complete window have distinct delivery identities and cannot share one reference output. Mass is a manufacturing inventory basis, not proof of equivalent installed area, thermal service or fixed service life.

Bau EPD original pages 4–6 and 10–11 support complete-window composition and prefabrication-dependent boundaries. Its four Austrian manufacturers and 2019 production sample provide no default for all wood industries, recipes, quantities or life cycles. See bau-timber-window-2022.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Use cp_mass to weigh each accepted complete same-configuration window net mass and sum cohort Q. Exclude packaging; impose no universal per-window weight. Frame or glazing mass cannot replace complete-window mass.
glass_area	glazing_unit	Area 93a60a56-a3c8-19da-a746-0800200c9a66	m2	Use cp_components measured delivered-assembly area. Numerator is area while inventory denominator remains 1 kg window. Opening area or an unverified kg/m2 factor cannot replace the declared area.
energy_unit	electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Retain meter kWh records; 1 kWh = 3.6 MJ. Verify <1 kV consumer supply and background region/year. This electricity unit rule establishes no net delivered steam heat.
wood_moisture	wood_blank, offcut, waste_wood	Mass	kg	Use dry-basis moisture u = (wet mass - oven-dry mass)/oven-dry mass; retain wet physical mass and dry wood separately. Wood mass excludes adhesive/coating. See usda-wood-handbook-2021 chapter 13.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased kiln-dried laminated spruce window stock and sealed triple-argon glazing assembly, each at an explicit delivery gate
starting_condition_role	Foreground machining/assembly feed; resource extraction and upstream manufacture carried by matching supplier backgrounds
product_classification_scope	Narrow complete-window route within 31621; excludes frame-only and French-window products
recursive_input_rule	Purchased same-category complete window is an explicit external input with its upstream link; do not recursively unfold this method indefinitely or relabel it as scantling
upstream_dataset_requirement	Stock lamination/drying, every glazing constituent, hardware manufacture/finish, each chemical and formulation burden, electricity and water need state-compatible backgrounds; UUID identity is not a complete dataset
disclosure	Declare site/time, delivered states, upstream gates, actual factory stages and meter coverage, recipe completeness, shared-load attribution, packaging and external waste destination

rule_id	Rule	source_ids
boundary_complete_window	Terminal complete-window boundary includes glazing, hardware, seals and retained finish; bare-frame output cannot replace it.	bau-timber-window-2022
boundary_upstream	Count upstream manufacture of purchased dried laminated stock and sealed glazing once. Moving processes upstream does not remove their burdens or biogenic CO2.	bau-timber-window-2022; usda-wood-handbook-2021
boundary_route	Include machining, finishing, assembly, acceptance, packaging and auxiliaries. Actual boilers, steam, on-site stock drying or glazing fabrication make this route inapplicable and require a new evidenced boundary; do not silently set them to zero.	bau-timber-window-2022

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
window_manufacture	Wood-window machining, finishing, glazing/hardware assembly, acceptance and packaging	required	Purchased dried laminated spruce stock and sealed IGU; electric route	One complete-window foreground unit with separate stage measurement	finished_window

All physical external rows use the same complete-period pool measured net finished mass Q under complete_period_normalization. Retain the unallocated process graph and wood mass, water, glazing and carbon balances. Stage transfers of the same material stay in raw records with equal amounts at both ends; no duplicate reference output is created. Keep a separate environmental attribution/allocation ledger: a burden share cannot reduce physical coproduct output. For supplier-made corner adhesive and each coating layer, retain one external exchange for each actual whole supplied formulation, including its carrier and additives; verify its own complete-product identity or keep a precise UUID-free row. The nine stable ingredient IDs glue_pvac, glue_water, coat_acrylic, coat_pur, coat_alkyd, coat_butoxy, coat_water, coat_tio2 and coat_pg also label composition/fate diagnostic records inside those formulations. Supplier-confirmed presence alone does not create a separate external purchase. Their Product input cards apply only to actual separately purchased compatible ingredients used in onsite preparation. Count actual onsite additions/mixing/dilution, supplier formulation/manufacture/preparation utilities and losses, packaging and delivery once at their actual boundary. Unknown composition or procurement remains a gap, not absence. Add each actual distinct supplied formulation, separately purchased additive, other packaging item or waste as a specific atomic row, never a collection label.

7. Allocation and Co-product Handling

rule_id	Rule	source_ids
allocation_subdivide	First subdivide the cohort by separate stage measurements from other products. Attribute shared energy only with measured operating-time/load causal evidence; disclose coverage and unmeasured shares rather than transferring industry averages.	bau-timber-window-2022
allocation_physical_ledger	Keep process graph, mass/water/carbon balances and coproduct outputs at full unallocated physical quantities. Allocate only in a separate environmental burden ledger. Internal links match at both ends; transferred offcuts cannot also fuel foreground.	bau-timber-window-2022
allocation_coproduct_review	Trace sold offcut use, price and treatment gate. The original EPD’s negligible-share rationale is no automatic allocation exemption. If measured causal subdivision is unavailable, declare alternative method, shares, rationale and sensitivity for independent methodological review; do not hide default credits.	bau-timber-window-2022

cp_mass	window_manufacture	accepted finished product	foreground and original records	product/configuration; unit serial; net weighed mass; tare; rejected output; cohort; Q	Weigh every accepted complete same-configuration window using a calibrated scale, excluding rack, film and straps; sum measured net masses to Q. No generic per-window mass. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	weighing and calibration records
cp_stock	window_manufacture	wood input	foreground and original records	supplier/lot; species; lamination; drying state; gross incoming mass; opening/closing stock; returns; moisture sample wet/dry mass	Weigh incoming stock and retained inventories; measure representative moisture by oven-dry comparison or calibrated species-specific meter cross-check. Supplier background includes drying/lamination. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg; %	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	scale, oven and supplier gate documentation
cp_formula	window_manufacture	each bought formulation; composition/fate diagnostics; actual separate ingredient purchases	foreground and original records	procurement status; supplier/product/layer; whole supplied formulation mass/state; complete component fractions/CAS; actual separate purchase receipts; opening/closing stock; unused returns; onsite additions/preparation; supplier manufacture/preparation utilities/losses/packaging/delivery; retained film; air/waste fate	Obtain complete supplier composition and actual whole supplied usage per product/layer; weigh and stock/return-adjust each whole formulation. Preserve listed nine ingredient IDs as separate composition/fate diagnostics using documented fractions; presence in a bought formulation alone creates no external ingredient purchase. External ingredient cards use actual separately purchased compatible quantities for onsite preparation only. Retain complete supplier formulation/manufacture/preparation utilities/losses/packaging/delivery once and genuine onsite mixing/additions once; do not add diagnostic ingredient burdens to an already complete formulation background. Unknown identity, fractions or procurement/boundaries stay specific gaps. Normalize each actual external whole-product or separate-purchase raw total once by Q under complete_period_normalization; never normalize a previously divided amount again.	kg	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	supplier formulation originals; batch/return and loss records
cp_components	window_manufacture	each purchased glass assembly and each hardware/seal part	foreground and original records	part/lot; material; finish; incoming installed rejected masses; delivered IGU area; individual pane schedule; argon; spacer; desiccant; seals; net geometry; thermal declaration	Weigh each material-specific part; measure each delivered IGU area and mass; verify constituent/geometry/performance original declarations and supplier manufacturing boundary.

Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg; m2	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	supplier bill of materials, drawings, performance originals and calibration
cp_energy	window_manufacture	electricity	foreground and original records	meter start/end; voltage; region/year; stage; compressed-air/extraction loads; other products; attribution basis	Meter each stage and shared auxiliaries; subtract separately measured unrelated consumption. Use measured operating-time/load evidence only when direct subdivision is unavailable; disclose unmeasured shares. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	MJ	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	meter records and attribution ledger
cp_water	window_manufacture	cleaning water	foreground and original records	supply meter; water specification; reusable volume; density if converted; discharge meter; opening/closing tanks; evaporation	Measure supply, reuse and external discharge separately; conversion from volume to mass requires measured temperature/density and compatible supplier quantity. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	meter, density and tank-balance records
cp_packaging	window_manufacture	each packaging item	foreground and original records	film grade; strap grade; rack species/net mass; shipped mass; scrap; return/reuse trips; opening/closing stock	Weigh film, rack and strap separately. Preserve full physical delivery quantities; retain an independent returnable-rack service ledger. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	weighing, dispatch and rack reuse records
cp_residues	window_manufacture	each coproduct or waste	foreground and original records	stream; contamination; wet/dry mass; glass assembly composition; storage changes; recipient; treatment; sold quantity; price	Weigh each separated stream and verify treatment/recipient; retain physical wood, water, glass and coating balance before environmental allocation. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	transfer tickets, assays, invoices and balance ledger
cp_emissions	window_manufacture	each outdoor species or disjoint particle interval	foreground and original records	species/CAS; air compartment; process; post-control concentration; exhaust volume; operating time; particle cutpoints; captured amount; detection limits	Use species-specific measured post-control releases for the cohort, including fugitive releases. Integrate calibrated concentration and compatible exhaust volume; unknown is not zero. Keep captured waste separate. Aggregate each atomic cohort exchange total divided by measured accepted net mass Q.	kg	each cohort and delivery	same declared production period and acceptance cohort	same factory, configuration and route	per 1 kg reference flow	sampling methods, assays and exhaust/control records

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
cohort_normalization	all inventory rows	Normalized row amount = net physical atomic cohort exchange total / Q; Q = sum of individually measured accepted complete-window net masses in the same cohort, kg. Output remains 1 kg; glazing is m2/kg, electricity MJ/kg, other rows kg/kg.	row protocol; cp_mass	normalized atomic exchange	bau-timber-window-2022
formulation_constituents	glue_pvac, glue_water, coat_acrylic, coat_pur, coat_alkyd, coat_butoxy, coat_water, coat_tio2, coat_pg	Diagnostic constituent mass = actual net whole supplied formulation usage × complete original supplier constituent mass fraction; calculate each product/layer separately, sum identical diagnostic constituent once and trace retained/air/waste/stock fate. These contained quantities are not external purchases or extra background exchanges. Whole bought formulations retain their own whole-product amount and matched complete supplier formulation/manufacture/preparation utilities/losses/packaging/delivery once; pure ingredient UUIDs cannot represent them. Only actual separately purchased compatible ingredients for onsite preparation use the corresponding external ingredient cards and measured stock/return-adjusted quantities, with onsite mixing/dilution/additions once. Do not add diagnostic constituent production burdens to a complete supplied-product background. Unknown complete-product identity, recipe or procurement remains pending.	cp_formula	diagnostic constituent/fate totals; actual whole-formulation and separate-purchase ledgers kept distinct	bau-timber-window-2022
physical_closure	wood_blank, offcut, waste_wood, glazing_unit, finished_window	Cohort inputs + opening stock = retained window composition + physical outputs/waste + releases + closing stock. Close dry wood, water, glazing and chemicals separately; carbon uses supplier/measured fractions, with no universal wood carbon fraction.	cp_stock; cp_formula; cp_components; cp_mass; cp_residues; cp_emissions	unallocated mass/water/carbon balances	usda-wood-handbook-2021; bau-timber-window-2022
particles_disjoint	pm25, pmcoarse, pmover10	If measurements are cumulative PM2.5, PM10 and total particulate, disjoint intervals are PM2.5, PM10-PM2.5 and total-PM10; require identical sampling, basis and control state, with nonnegative intervals. Incompatible measurements cannot be subtracted.	cp_emissions	three disjoint measured intervals
complete_period_normalization	all inventory rows	Every existing campaign, batch or lot amount rule and linked collection protocol uses one documented complete reporting-period pool for the same declared product, grade, route, configuration, site and reference state. Accepted-lot wording identifies the denominator only; retain all attributable startup, shutdown, wholly failed or zero-output batches, rejects, work in progress and rework in the raw native-unit numerator records. Count reworked reference product once only when finally accepted. Sum each attributable exchange over this matched pool, divide once by its strictly positive accepted reference-product quantity in the declared denominator unit, and scale to the declared reference quantity. Do not average batch ratios, drop a failed batch, pool unrelated products/periods or replace native numerator units. If the entire matched pool has no accepted output, retain the unnormalized absolute inventory and require review; issue no normalized result or fabricated output. Preserve stock/return and physical-transfer ledgers independently of burden allocation; allocation never removes already-incurred failed/rework activity.	all linked raw collection protocols; accepted reference-product pool; stock and rework links	native exchange unit per declared reference quantity; zero-output pool remains unnormalized

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_scope	all inventory rows	Match configuration, species, moisture, glazing and delivery route; source averages serve only as boundary evidence.	supplier and acceptance originals
dq_recipes	cp_formula	Resolve every actual adhesive, primer, preservative treatment and finish composition and fate under the listed ingredient IDs; unknown additives/fractions block composition completeness and cannot default to zero. Separately verify each actual whole supplied formulation or true separately purchased ingredient, its physical identity/reference basis and compatible supplier/onsite preparation boundary. Composition presence alone does not establish procurement.	complete recipes, procurement originals and whole-product/diagnostic/separate-purchase usage ledgers
dq_coverage	all inventory rows	Retain metering period, calibration, stocks and detection limits; distinguish missing, below-detection and evidenced inapplicability.	raw records and coverage table

9. Validation Rules

rule_id	Rule	source_ids
validate_reference	Exactly one terminal complete-window output uses the 1 kg measured net complete-window basis. Do not substitute frame or glazing UUIDs, or hide known identity to evade multiple-output checks.
validate_native_quantities	Measured glazing assembly area matches upstream Area/m2; window/opening area and thermal performance come from measurement/originals and establish no fixed mass or lifetime.	bau-timber-window-2022
validate_atomic	Each external row contains one actual supplied physical product or released species; each bought whole formulation remains one product, while ingredients contained in it remain composition/fate diagnostics and are not additional purchases. Ingredient external cards apply only to actual separate purchases for onsite preparation. Add each actual distinct formulation, separately purchased additive, glazing assembly and hardware item separately; verify whole supplied identity/reference basis, supplier manufacture/preparation/delivery and actual onsite additions once. Verify elementary species, medium/submedium, unit and fossil/biogenic origin where applicable; correction flows and broad substitutes are prohibited.
validate_balances	Check unallocated physical mass/water/carbon balances separately from environmental allocation. Do not double-count particles or delete background/actual combustion biogenic CO2 from LCI because of a GHG impact convention. Foreground combustion requires a new boundary and is not covered by this route.
validate_completeness	Missing reference identity, complete recipe, upstream compatibility, actual measurement or unresolved relationships remain incomplete; tool failure and unsupported relationships cannot be reported as passing.

10. Published Dataset Profile

Field	Value
dataset_role	Factory-gate foreground manufacturing process linked to verified upstreams
downstream_use	secondary_dataset; background_dataset
allowed_use	Manufacturing inventory for the declared single-sash spruce, triple-argon glazing, electric machining/assembly route
excluded_use	Full CPC coverage; frame-only or French-window products; equivalent thermal-service comparison; fixed service life; building EPD certification
required_metadata	Site/time, configuration, measured net mass, separate areas, performance originals, incoming states, component recipes, meter coverage and upstream gates
required_quality_disclosure	Missing identities, recipes and background compatibility; sampling uncertainty; shared-load attribution; allocation method and sensitivity
update_trigger	Changed configuration, species, glazing/recipe, gate, energy route, supplier background or methodological evidence
