As energy codes evolve and climate goals become more urgent, net-zero construction is no longer a future concept—it’s here now. Whether you're building new or retrofitting, the building envelope is where net-zero performance starts.
What Is a Net-Zero Building?
A net-zero building produces as much energy as it consumes annually. That requires:
High-efficiency HVAC systems
Solar energy or renewable sources
And most critically—a super-sealed, insulated building envelope
Top Envelope Upgrades for Net-Zero Goals
Exterior Insulation (CI Systems): Continuous insulation prevents thermal bridging and enhances overall R-value.
Airtight Layers: Taped sheathing, air barriers, and weatherproof membranes are essential to eliminating drafts.
High-Performance Windows & Doors: Triple-pane units with thermally broken frames and insulated sills are key.
Rain-Screen + Durable Cladding: Helps manage moisture while protecting the insulation and structure.
Integrated Detailing: Proper flashing and seals ensure long-term air and water control.
Accent Exteriors works with designers and builders to deliver envelope systems that meet Passive House, Step Code, and net-zero performance standards without compromising on budget or style.
