What is a net-zero home?
A net-zero energy home is engineered to produce as much energy as it consumes over a year, resulting in net-zero carbon emissions from building operations.
These homes are not simply energy-efficient — they are fully optimized systems that balance passive and active performance measures, integrating advanced construction techniques with renewable energy generation.
At Hapi Homes, every model is built to support net-zero energy readiness through a combination of:
- High-performance thermal envelopes
- Smart architectural orientation and passive design
- Solar-ready infrastructure
- Advanced mechanical and energy systems
Whether you’re installing a compact ADU in Los Angeles or a multi-bedroom home in Austin, Hapi Homes applies net-zero principles as a standard, not an option.
Why net-zero homes matte
Reduced costs
Optimized building envelopes paired with on-site energy generation (typically photovoltaic systems) allow for significant reductions — or elimination — of monthly utility bills. Over a 10–20 year horizon, this translates to $30,000–$80,000+ in lifetime energy savings, depending on climate and usage.
Superior indoor environmental quality (IEQ)
Airtight assemblies, balanced ventilation, and high-performance insulation systems reduce thermal fluctuations, improve indoor air quality, and limit condensation risks, supporting occupant health and comfort.
Environmental impact
The built environment is responsible for ~39% of global CO₂ emissions. Net-zero homes significantly reduce Scope 1 and 2 emissions by cutting direct energy consumption and indirect upstream impact.
How Hapi Homes builds for net-zero
Unlike traditional builders who retrofit sustainability, Hapi Homes starts with it. From the ground up, every home we design is optimized for performance and efficiency.
High-performance building envelope:
- Precision panelization with pre-cut, tightly toleranced components
- Continuous insulation in walls, roof, and floor assemblies (R-value optimized by zone)
- Airtight construction targeting ≤ 1.5 ACH50 (Air Changes per Hour @ 50 Pascals)
- Low-emissivity glazing, typically double-pane, with solar heat gain control (SHGC optimized)
On-site renewable infrastructure
- Solar-ready roof structures engineered for PV load and orientation
- Conduit pathways and inverter space pre-integrated
- Optional solar + battery system coordination via our installer marketplace
Passive design integration
- Building orientation to maximize winter sun and minimize summer heat gain
- Overhangs and shading are calculated based on solar path diagrams
- Natural cross-ventilation is enabled through operable windows and strategic airflow paths
Energy & mechanical systems
- Heat pump HVAC systems with zoned control
- ERV or HRV ventilation for healthy, balanced indoor air
- Induction cooktops, Energy Star appliances, and low-load lighting systems
- Optional EV charging & greywater systems
The Hapi Homes process for going net-zero
Model selection & climate adaptation
We advise on layouts that reduce conditioned volume, improve solar gain, and work with your specific site conditions.
Design customization
Through our digital configurator, you can add energy upgrades including rooftop solar, battery storage, induction appliances, low-flow fixtures, and passive solar features.
Certified installation
Our Certified Installer Network follows exacting standards to ensure every component — from floor panel to roofline — is installed to performance specs. We also offer field support and QA documentation.
Financing Pathways
We partner with lenders that offer green build loans, PACE financing, and other incentives that support sustainable construction, often with reduced rates or enhanced terms.
Want to go fully net-zero?
- Model selection guidance: We recommend layouts that minimize energy loads for your site and climate zone.
- Design customizations: Add solar, battery backup, EV charging, and energy-efficient appliance upgrades.
- Installer coordination: Our certified installer network ensures your home is delivered and sealed to net-zero specifications.
- Financing support: We work with lenders offering green home loans that reward net-zero builds.
The Hapi Homes difference
Unlike panelized systems, every Hapi Home is engineered to be net-zero capable and designed to deliver more than just energy savings:
- Architectural quality
- Digital-first customization
- 2–4 month build timeline
- Modern living, made smarter
Whether you’re building your forever home, a rental ADU, or a weekend retreat, net-zero is no longer the future. It’s the standard.
What Makes Hapi Homes Different?
No matter your lot size, lifestyle, or long-term goals, there’s a backyard ADU that can work for you — and we’ve built our entire platform around making that process simple, fast, and customizable.
From a compact Junior ADU conversion to a modern two-story rental-ready retreat, Hapi Homes gives Californians a more innovative, faster, more transparent way to build.
