FAQ
Public answers on BIPV, products, studies, green building programs, and tax modelling — without gated capital-stack economics.
Core
Core BIPV questions in public, machine-readable language without gated project economics.
BIPV is solar photovoltaic material that replaces conventional building envelope material - such as spandrel, curtain wall, or cladding - rather than being mounted on top of it. The glazing itself generates electricity while serving its normal facade role.
Powerglass supplies and integrates CdTe (cadmium telluride) thin-film photovoltaic glass, which performs comparatively well in the diffuse and lower-light conditions common across Canadian climates relative to crystalline silicon. CdTe requires proper encapsulation and an end-of-life handling program, consistent with any semiconductor glazing product. Powerglass does not manufacture the underlying CdTe semiconductor technology.
No. Powerglass supplies material only. Installation, EPC, and general contracting are handled by the project's own contractor team; compliance submissions (LEED, TIER, NECB, municipal energy codes) require qualified engineers, energy modellers, and LEED Accredited Professionals.
No. On-site generation can reduce operating cost exposure over the building's asset life, but outcomes depend on project-specific scope, incentive eligibility, and electricity rates. Powerglass does not represent any project as self-funding, and full capital-stack economics are prepared only after a project-specific review.
Products
Product guidance for architects and envelope teams. Public copy stays qualitative and pricing-free.
Powerglass offers five CdTe BIPV glazing product lines: COM-M1 (opaque spandrel), COM-CA2 (architectural/stone-texture glazing), COM-CBS1 (coloured/designer glazing), COM-Z3 (vision-zone glazing), and COM-S1 (railing/safety glazing) - covering opaque, vision, coloured, and railing applications in a single coordinated envelope.
Powerglass COM series catalog entries are wind-load tested to 2400 Pa, with a CdTe temperature coefficient of -0.189%/°C engineered for -40°C to +85°C operation. COM-S1 safety/railing laminate is ANSI Z97.1 impact-rated; impact rating for other lines is confirmed at product submittal for the project specification.
COM-CA2 and COM-CBS1 support stone-look, coloured, and designer glazing textures in standard curtain-wall coordination, allowing architects to specify active solar glazing without changing the intended facade language.
Studies
Methodology, city-adjusted generation, and illustrative context. Project-specific economics remain gated.
Each case study uses Natural Resources Canada (NRCan) vertical south-facing reference yield data for the specific city, an illustrative facade area, and a disclosed electricity rate to estimate annual generation and energy value. Capital-stack economics (incentive treatment, payback, net premium) are prepared only after a project-specific review confirms scope, ownership, and baseline material - they are not published publicly.
Each scenario is compared against the specific supply-only traditional material it displaces - for example, metal cladding, precast panel, stone cladding, or designer glass - so outcomes reflect the actual displaced material cost, not a single blended industry figure.
No. Case studies are illustrative financial models using disclosed assumptions, not delivered projects. Orientation, shading, current material pricing, incentive eligibility, and tax treatment must be validated for the actual site.
Green building
Program fit, emissions framing, and valuation context. Compliance submissions stay with qualified professionals.
On-site BIPV generation can contribute to LEED Canada (CaGBC) EA Credit: Renewable Energy Production and EA Credit: Optimize Energy Performance when included in the project's whole-building energy study by a qualified LEED Accredited Professional. Powerglass supplies material only and does not perform LEED submissions.
On-site generation displaces grid electricity, which can reduce Scope 2 emissions relevant to Alberta's TIER regulation for applicable facilities. Actual TIER credit treatment requires project-specific accounting by a qualified Alberta-registered GHG auditor; Powerglass does not provide TIER compliance advice.
Buildings unable to demonstrate a decarbonization trajectory face a valuation discount at disposition, a pattern identified by CBRE Canada and Altus Group. A BIPV facade can help mitigate that risk over the asset life by converting a sunk facade cost into an income-producing building element.
Tax information
Modelling assumptions and source pathways only. Eligibility depends on the project, owner, and filing position.
BIPV facade material may qualify as clean technology property under the federal ITC and CCA Class 43.2, depending on ownership structure, commissioning, and tax position. This is illustrative only - not tax, legal, or investment advice - and must be confirmed with a qualified tax advisor for the specific project.
Capital Cost Allowance Class 43.2 provides accelerated depreciation treatment for qualifying clean energy equipment. Eligibility and the applicable rate depend on the specific asset, ownership, and tax filing position; project teams should confirm treatment with their accountant before relying on any modelled figure. Powerglass modelling uses a conservative Class 43.2 treatment for screening only.
No. Provincial rules vary significantly and change over time - for example, net metering export rates and program availability differ by province and have changed in some provinces. Current program status should always be verified with the applicable provincial utility regulator rather than assumed from a general model.
