Intelligent Energy Group

What Intelligent Energy Group does

Intelligent Energy Group (IEG) is a private, U.S.-based energy services company headquartered at 145 Huguenot Street, New Rochelle, New York, operating under the NovaVu brand. The company was founded with the goal of applying aerospace technology to building energy efficiency, and it serves two primary customer segments: owners of multi-family residential buildings and owners of large commercial buildings with fixed window systems.

IEG's core product is the NovaVu advanced secondary window insert — a custom-measured, custom-manufactured double-pane clear polycarbonate unit gasketed and mounted within an integrated structural frame. The insert installs into the interior frame of an existing window without cutting, drilling, or caulking, converting single- or double-pane windows into triple- or quadruple-pane configurations with three thermal airspaces. The system is protected by U.S. Patent No. 12,523,087 (awarded January 13, 2026) and features advanced gasketing tested by Intertek to reduce air infiltration by 99% or more.

The business model is direct sales of custom-manufactured hardware to building owners and property managers, supported by an enterprise field-sales motion targeting commercial and multi-family residential projects. Pricing is custom and not publicly disclosed; the company emphasizes cost advantages (up to 75% less than replacement windows, ROI typically under 5 years) and eligibility for utility rebates and accelerated depreciation. IEG operates a partnership with State Window Corporation, a full-service facade provider, to extend reach into building envelope projects. The company has 1–10 employees, no disclosed funding, no disclosed revenue, and a U.S.-only footprint currently centered on New York.

Core offering

Intelligent Energy Group manufactures and sells NovaVu, a patented advanced secondary window insert system made of double-pane clear polycarbonate with proprietary gasketing, mounted in an integrated structural frame. The custom-measured inserts convert existing single or double-pane windows into triple or quadruple-pane units with three thermal airspaces, reducing window heat loss by 50%, eliminating 99% of drafts, blocking 99% of UV radiation, and reducing outdoor noise by 20–40%. The product is sold for commercial buildings and multi-family residential applications at a fraction of the cost of window replacement.

Product overview

Intelligent Energy Group (IEG) offers NovaVu, a patented advanced secondary window insert system. The product portfolio includes NovaVu Window Inserts as the core product, available in two application variants: Commercial Window Inserts for commercial buildings and Residential Window Inserts for multi-family residential buildings. NovaVu inserts convert existing single or double-pane windows into triple or quadruple-pane units using double-pane clear polycarbonate with advanced gasketing, providing thermal insulation, UV protection (99%), and noise reduction (20-40%). The inserts are custom-measured and manufactured for precise fit, installed without cutting, drilling, or caulking, and come with a 10-year warranty.

Scale indicators3 records

Recent moves5 records

Expansion highlights4 records

Broad incumbents

• Marvin: Marvin is a premium window and door manufacturer serving residential and commercial projects, including large fixed-window commercial facades. It competes with NovaVu in the high-end retrofit and new-construction envelope market.
• Pilkington: Pilkington is a global glass manufacturer, including energy-efficient and low-emissivity products used in windows and facades. It represents the incumbent glazing-supply ecosystem that the NovaVu insert retroactively competes with for thermal performance.
• Pella: Pella is a large-scale window and door manufacturer with deep installer and dealer networks across residential and commercial segments. It represents the full-replacement alternative that NovaVu positions against on cost and disruption.
• Guardian Glass: Guardian Glass is a large float glass and IGU manufacturer with commercial and residential product lines. It supplies the high-performance glazing alternatives that NovaVu is positioned against in the commercial retrofit market.
• Andersen Windows: Andersen is a major incumbent window and door manufacturer with broad residential and commercial product lines, including replacement windows. It competes for the same retrofit-spend budget as NovaVu via full replacement rather than inserts.
• Eastman Chemical (Heat Mirror / Southwall): Heat Mirror by Eastman (formerly Southwall Technologies) is a suspended-film insulating glazing technology used inside multi-pane window assemblies. It targets the same multi-pane thermal performance improvement that NovaVu achieves via polycarbonate inserts.
• Cardinal Glass Industries: Cardinal is a major manufacturer of insulated glass units (IGUs) and low-e coated glass used in residential and commercial windows. Its IGU technology competes architecturally with the multi-pane performance NovaVu claims to replicate with inserts.

Direct peers

• Indow: Indow is a direct competitor in the interior window insert / secondary glazing category, selling custom-measured acrylic inserts that improve comfort and energy efficiency. It is the closest comparable to NovaVu's value proposition and target buyer (building owners, multi-family, commercial).

Emerging players

• View (View Dynamic Glass): View manufactures electrochromic smart glass for commercial facades that reduces solar heat gain and improves energy performance. While a different mechanism, View competes for the same commercial retrofit envelope-spend that NovaVu targets.

Others

• 3M Window Films: 3M supplies architectural window films for UV blocking, solar control, and safety glazing. Films are an alternative (non-insert) retrofit approach that building owners sometimes choose instead of inserts like NovaVu for similar energy/comfort outcomes.
