SageGlass at a glance: products and EPDs

What SageGlass makes

SageGlass focuses on electrochromic insulating glass units for building envelopes. Think facades, windows, curtain wall infills, and skylights that tint automatically or on command to cut glare and solar gain while keeping views.

Product families typically include classic full‑pane tinting, in‑pane gradient options like Harmony, plus controls and sensors that tie into BMS platforms. Their sustainability page outlines use cases across offices, healthcare, and airports.

Product breadth and likely SKU count

This is a focused portfolio rather than a broad building‑materials catalog. Within dynamic IGUs, you will find variations by thickness, coatings, laminate makeups, acoustic interlayers, color, and DGU vs TGU build‑ups. That quickly adds up to dozens of sellable configurations, and for large projects, into the low hundreds.

Where the EPDs stand in 2025

SageGlass has current, product‑specific EPDs covering its core electrochromic IGUs. At minimum, a triple glazing unit EPD published in 2025 lists validity through May 29, 2030 and applies to Europe and the USA, verified under EN 15804+A2 and ISO 14025 (EPD International, 2025) (EPD International, 2025). That scope aligns with how most specs buy dynamic glass today, especially for unitized curtain wall packages.

Energy impact, in plain numbers

Field and modeling studies from Lawrence Berkeley National Laboratory report perimeter‑zone energy reductions of roughly 10 to 20 percent in many climates for electrochromic windows with daylighting controls, with peak demand reductions commonly in the 20 to 30 percent range for large window walls. Peak cuts around a quarter have been observed in monitored testbeds on clear sunny days (LBNL, 2004; LBNL, 2006) (LBNL, 2006). This is the kind of evidence teams can reference in design narratives alongside a product‑specific EPD.

Coverage strengths and likely gaps

Coverage is strong on the core IGU builds that most facade contractors procure. Where questions can arise is at the variant level. A specifier may ask whether gradient‑tint SKUs, special laminates, or project‑specific acoustic stacks are explicitly enumerated in the EPD scope. Controls hardware and wiring are typically outside a glass EPD boundary, which is normal, but worth stating clearly in submittals.

If a high‑volume SKU is marketed under a distinct sub‑brand yet maps to the same manufacturing recipe, add an appendix that names it explicitly in the EPD or publish a variant EPD. That small paperwork step can remove friction for LEED v5‑minded reviewers who scan documents quickly.

The competitor set you will meet on bids

On like‑kind dynamic glass, the most frequent comparables are View and Halio. View has previously published a third‑party verified EPD for its dynamic glass, though age and current validity should be checked during submittals. Halio markets fast tint switching and is building partnerships with major fabricators. In substitution discussions, static solar‑control options also show up, such as low‑e IGUs paired with interior or exterior shading from large float‑glass suppliers. Those suppliers publish fresh EPDs for flat and processed glass, for example Guardian’s 2024 updates that report about 1,102 kg CO2e per ton A1‑A3 for unprocessed flat glass in North America (Guardian Glass, 2024) (Guardian Glass, 2024).

Where missing EPDs could cost spec wins

If a project mandates product‑specific EPDs, a dynamic IGU without one forces the design team to assume conservative generic impacts that can ding their carbon budget. In that head‑to‑head, a rival with a current EPD can look like the safer, faster path. A practical example is a skylight package that uses an electrochromic IGU but ships as a system. If the IGU has an EPD yet the full skylight is silent, call out system boundaries in the cover sheet so reviewers understand what is and is not included. Otherwise, bids risk delay.

What manufacturers can do next

Keep the scope product‑forward. Match the EPD PCR to the category your competitors use so the comparison is apples to apples. Name high‑volume variants in the EPD text so reps are not emailing clarifications every week. Make data collection painless inside the plant. The fastest programs are the ones that wrangle utilities, bills of materials, and waste streams up front, then publish with the operator your market trusts.

Bottom line for the spec table

SageGlass is a pure play in dynamic IGUs with EPD coverage that reaches the core of what owners actually buy. Fill any remaining paperwork gaps around variants and packaged systems, and the product moves from enviromental nice‑to‑have to default choice on LEED‑oriented projects. The ROI often shows up not in a single rebate, but in fewer objections and more awarded alternates when carbon is a gating criteria.
