HAWAII'S PREMIER ARCHITECTURE FIRM: General Architecture & Net-Zero Building

11/05/2026

Modern Man. Modern Luxury Hawaiʻi named David E. Sellers, AIA, principal of Hawaii Off Grid Architecture & Engineering, one of its 2026 Modern Men.

"Architects solve real problems, prove sustainability makes financial sense and leave a lasting community legacy."

The Nov/Dec 2026 digital feature is live, and the print issue is on shelves this month. Photography by Courtney Maui Visual.

Mahalo to Modern Luxury Hawaiʻi. The team will celebrate at Velocity Honolulu on November 22.

In good company. Architizer named Hawaii Off-Grid Architecture & Engineering one of "7 Firms at the Forefront of Sustainable Architectural Practice," drawn from the Best in Sustainability Firm category of the 14th Architizer A+Awards.

The feature highlights two of our projects: Ohana Hope Village in Kahului and Kailua in Maui County.

Architizer writes that we approach sustainability "as a measurable performance goal, designing buildings to achieve at least net-zero energy use," combining passive climate strategies, renewable energy systems and carbon-conscious materials.

Mahalo to Architizer for including us alongside tono Inc., Green Architecture Design & Research Institute of CADG, ZGF Architects, TROOST + PESSOA Architects, KPF and Hennebery Eddy Architects.

A century of AIA Hawaiʻi. On Friday, Oct 23, David joined fellow AIA Hawaiʻi State Council board members in the Governor's Ceremonial Room at the State Capitol in Honolulu, where Governor Josh Green presented a proclamation recognizing the AIA Hawaiʻi Centennial.

“Celebrating AIA Hawaii’s 100th year is an honor and a highlight of my career. Mahalo to the AIA for all it has given me, and especially our community in its time of need. Mahalo to Governor Green for this recognition, to my colleagues, and to all who came before us and set the values that guide us today.”

Bunkhouse update. Matt Kopp walks us through where our Habitat for Humanity mass timber bunkhouse stands today.

The exterior building wrap is on, and the Marvin windows are installed and flashed. Last week volunteers came out to install the roofing system. Next up, Kapili Roofing puts on the roof using material they generously donated. After that comes the exterior envelope, with Rockwool rigid insulation and Hardie board, both donated as well.

Mahalo to everyone helping bring this one home. More soon.

Why the wall works.

David Sellers breaks down what goes into every Surf Block wall:

Resistant to earthquakes and hurricanes.
Twice the R-value required by code.
Non-combustible.
Resists termites and mold.

For Maui, and for the Lahaina rebuild, the wall itself matters. Built to last in the place we live.

Solar you can see.

At the Hawi Residence on Hawaiʻi Island, net-zero was non-negotiable from day one. So instead of hiding the system, we made it part of the architecture: an overhead solar awning built with about 30 Lumos Vision modules, supplemented by additional PV to meet the home's energy needs.

Our architects and in-house solar install team worked side by side from the start, designing around a system that was meant to be seen. The array, the water infrastructure and the other sustainable systems are visible throughout the property, part of the experience of the home.

Off grid in Hawi also means planning every material and every piece of equipment ahead, and it means real energy independence through intense weather and outages.

Designing a school rooted on Maui.

A first look at early concept renderings for our Mass Timber School Project. Learning spaces are organized around courtyards and covered play areas, with a dining commons that opens towards Haleakalā. The campus is designed for wind and sun, with the goal of a net-zero-energy school.

Mass timber brings warmth, strength and a lower carbon footprint to the places keiki learn every day. Exposed wood structure, natural light and open air connections make the building part of the lesson.

Shade that pays for itself.

A solar canopy over the lanai. It cools the outdoor living space and feeds the house from the same structure. Exposed steel framing, a standing seam roof, and deep overhangs are built for Maui sun and trade winds, with the view left open.

Off grid doesn't have to mean giving anything up. It just means designing smarter from the start.

Keeping foam out of the landfill. At Hawaii Off Grid, waste surfboard foam is diverted from the Maui landfill, ground into beads and cast into Surf Block walls. Each block is about 85% recycled foam, non-combustible and wildfire resilient. Less waste in the ground, more resilient homes, made on Maui.

Mahalo, Central Maui, for showing up.

Families and neighbors came out to both sessions of Informational Open House II for the New Central Maui School, Thursday evening and Saturday afternoon in the Cafetorium at Puʻu Kukui Elementary. You walked the boards, from the site plan and site access to how culture, art and place can shape the campus, and you talked story with our team. Every question and idea helps shape a school that reflects this community.

Phase I opens as a middle school in 2031, and the full campus will serve up to 1,650 students. We're proud to be the architect of record, and grateful to be designing it alongside the people it will serve.

Mahalo to the Hawaiʻi School Facilities Authority for hosting, and to everyone who brought their questions, their ideas and their ʻohana.
