Z Group at the 2026 Green Expo: Advancing Sustainable Architecture in Aspen
Aspen architects join CORE and the Roaring Fork Valley community to explore the future of sustainable buildings and climate-conscious design.
On September 11, Z Group Architecture & Interior Design joined sustainability leaders, building professionals, and community members at CORE’s 2026 Green Expo at Aspen Meadows.
Hosted by the Community Office for Resource Efficiency (CORE), the annual Aspen event brought together more than 20 businesses and organizations working across climate, energy, and the built environment. The afternoon included a Solutions Showcase, a panel exploring the future of sustainable buildings, and opportunities for conversation and collaboration.
Sustainable Architecture Rooted in the Roaring Fork Valley
For Z Group, sustainability is not a separate layer added to a project. It is part of a larger commitment to designing architecture that responds thoughtfully to its site, its occupants, and the surrounding landscape.
At the Green Expo, our team shared examples of how that philosophy is being translated into practical strategies across residential, hospitality, mixed-use, and community architecture in Aspen and the Roaring Fork Valley.
Our Sustainability Showcase featured projects incorporating strategies such as solar power and battery storage, ground-source heat exchange, structural insulated panel construction, LEED-certified design strategies, building-envelope improvements, electrification, and passive solar shading.
Among them, The Inn at Aspen features a 243.2 kW solar array with 608 panels, identified in our event handout as the largest private array in the Roaring Fork Valley. The Farm Collaborative’s new Welcome and Learning Center incorporates structural insulated panel construction alongside a 22 kW solar array and battery storage, while River House, a new single-family residence, incorporates a 10-well ground-source heat-exchange system.
Reimagining an Aspen-Area Architecture Office for the Future
Our Green Expo display also highlighted the ongoing transformation of Z Group’s office at 208 Midland Avenue in Basalt, a project completed in partnership with CORE.
The architecture office remodel preserves a historic façade dating to 1894 while improving the performance of the building behind it. The design includes a fully re-insulated core structure, low-E triple-pane windows, conversion from gas to an electric heat pump, and custom window boxes and louvered steel overhangs informed by passive-shading studies.
It is a fitting example of an idea central to Z Group’s work: the most sustainable path forward does not always mean starting over. Thoughtful architecture can honor the story of an existing place while adapting it for a more resilient future.
Collaboration Is Part of Sustainable Design
CORE describes the Green Expo as an opportunity to explore practical solutions for reducing carbon emissions, with this year’s programming examining technologies, design strategies, policy, financial incentives, and grid resilience as interconnected parts of building decarbonization.
That collaborative approach resonates deeply with Z Group.
Since our beginnings in Aspen in 1952, our work has been shaped by the relationship between architecture and the extraordinary environment of Colorado’s mountain communities. Today, that legacy continues through an evolving understanding of what responsible design can accomplish—for our clients, our communities, and the landscapes we share.
Thank you to CORE and everyone who stopped by the Z Group table to exchange ideas about the future of sustainable design in the Roaring Fork Valley.

FAQs: Frequently Asked Questions About Sustainable Architecture in Aspen
What is Z Group’s approach to sustainable architecture in Aspen?
Z Group Architecture & Interior Design approaches sustainability as an integral part of site-sensitive design. The firm considers building performance, energy use, materials, passive design, renewable energy, and the relationship between architecture and the surrounding landscape. Across projects in Aspen and the Roaring Fork Valley, Z Group has incorporated strategies including solar power, battery storage, ground-source heat exchange, high-performance building envelopes, electrification, passive shading, and LEED-focused design.
What sustainable design strategies does Z Group use?
Sustainable strategies vary according to each project, site, and client. Z Group’s Green Expo Sustainability Showcase featured solar arrays, battery storage, ground-source heat exchange, structural insulated panels (SIPs), low-E triple-pane windows, electric heat pumps, passive shading, and LEED-certified design strategies.
Does Z Group design energy-efficient homes in Aspen and the Roaring Fork Valley?
Yes. Z Group designs residential architecture with sustainability and site sensitivity as core considerations. For example, the firm’s River House, a new single-family residence, incorporates a 10-well ground-source heat-exchange system with 289.5 kBtu total production.
Does Z Group work on sustainable commercial, hospitality, and community projects?
Yes. Z Group’s sustainable design experience spans multiple building types. Projects highlighted at the 2026 Green Expo included The Basalt River Park Gallery, a mixed-use development; The Inn at Aspen, a multifamily and hospitality renovation; The Farm Collaborative, a new Welcome and Learning Center; and residential work including River House.
How does Z Group incorporate solar energy into architecture?
Solar design is evaluated according to the needs and opportunities of each project. The Basalt River Park Gallery incorporates a 40 kW solar array with battery storage, while The Farm Collaborative features a 22 kW solar array with battery storage. The Inn at Aspen incorporates a 243.2 kW array with 608 solar panels, identified in Z Group’s Green Expo materials as the largest private solar array in the Roaring Fork Valley.
Can historic buildings in Colorado be made more energy efficient?
Z Group’s remodel of its architecture office at 208 Midland Avenue in Basalt, Colorado demonstrates one approach to improving an existing historic building. The project preserves a historic façade dating to 1894 while incorporating a fully re-insulated core structure, low-E triple-pane windows, conversion from gas to an electric heat pump, and calculated passive shading using custom window boxes and louvered steel overhangs. Z Group partnered with CORE on the project.
Why is site-sensitive architecture important in Aspen and Colorado’s mountain communities?
For Z Group, site sensitivity means designing architecture that responds thoughtfully to its environment rather than treating the landscape as a backdrop. The approach is rooted in the firm’s long-standing philosophy of creating architecture that lives in harmony with the landscape while considering sustainability, natural and local materials, human experience, and the relationship between nature and architecture.
Who is CORE, and what is the Green Expo?
CORE—the Community Office for Resource Efficiency—organizes the Green Expo in Aspen as a community event focused on climate, energy, and the built environment. Z Group participated in the 2026 Green Expo, sharing examples of sustainable architecture and building-performance strategies from projects throughout Aspen and the Roaring Fork Valley.
How can I work with Z Group on a sustainable architecture project in Colorado?
Z Group Architecture & Interior Design works across residential, hospitality, commercial, institutional, and community-focused architecture and interior design. Clients interested in sustainable, energy-conscious, and site-sensitive design can connect with the Z Group team to discuss how environmental goals can become part of a project’s larger architectural vision.
