Building Retrofit Expert Interview Series

Navigating Code Compliance and Grant Requirements for Nonprofit Retrofits


There’s a well-known adage in the green building community—that “the most sustainable building is the one that already exists.” It’s a sentiment that drives the work of Maria Bergh, Founder and Architect at We Build Agency and lead architect on the nonprofit Plant Chicago’s adaptive reuse of a 100-year-old-plus Chicago Firehouse into their new, sustainable headquarters and indoor urban farm. Maria recently sat down with us to discuss her experiences retrofitting older buildings in Chicago for nonprofit and small business clients, and provide lessons for other design and construction professionals.

How Architects Can Drive High-Performance Office Fit-Out Projects

March 10, 2025
Resource Overview Architects are essential players in designing, constructing, and operating high-performance spaces for tenants, the demand for which continues to rise. Half of all commercial buildings in the US are leased, and retrofitting existing buildings is a must for meeting our evolving climate and emissions targets. How can architects take advantage of this opportunity, and get involved in these projects? TEOP for Architects takes ULI’s established Tenant Energy Optimization Program (TEOP), a 10-step process for embedding energy efficiency into leased spaces during initial fit-outs or significant renovations, and shows how architects can plug in and use it to streamline their work. Drawing on interviews with architects and real estate professionals from firms leading in sustainability, TEOP for Architects is filled with practical advice and data points for addressing common barriers, whether it’s how to approach clients that are new to sustainability, how to integrate energy modeling into your practice, or how to ensure building operations help meet initial performance goals. TEOP for Architects shows that tenant spaces are just as ripe for design excellence and innovation in performance as new construction. Whether you’re an experienced architect just getting familiar with tenant fit-outs or you’re entirely new to the world of sustainability, TEOP for Architects can help you get situated and start delivering the efficient, elegant projects that clients and the climate both need.

Fitting Out Spaces for Net Zero

March 10, 2025
Resource Overview Fit-outs tend to attract less attention than the construction and operation of buildings, despite the fact that it has a significant impact on the operational performance of the occupied space. In addition, in nondomestic buildings, the interiors can be replaced every three to 10 years, making fit-outs a crucial part of a building’s life cycle. This tenant primer focuses on the importance of fit-outs.

Tenant Energy Optimization Program

March 7, 2025
Resource Overview The Tenant Energy Optimization Program Infographic provides stakeholders with an overview of ULI's TEOP program as well as an outline of the 10-step process which outlines steps you can take to integrate energy efficiency into tenant space, design, and construction.

Green Leasing as Part of a Sustainable Tenant Fit-Out

March 6, 2025
Resource Overview Building owners and tenants are often characterized by conflicting interests and split incentives, hindering joint efforts towards energy efficient buildings. However, both parties play a vital role in embedding sustainability into the built environment and ultimately have common ground that can be leveraged to achieve shared goals. The Urban Land Institute’s (ULI) Tenant Energy Optimization Program (TEOP) and the Institute for Market Transformation (IMT) and U.S. Department of Energy’s (DOE) Green Lease Leaders program share complementary, actionable steps for landlord-tenant collaboration in advancing sustainability in leased spaces. Green Leasing as Part of a Sustainable Tenant Fit-out: Tenant Energy Optimization Program and Green Lease Leaders Program provides an overview of TEOP and Green Lease Leaders, highlighting how the two programs can work together to offer a robust roadmap for landlord-tenant energy efficiency achievements.

Green Lease Leaders

January 20, 2025
Resource Overview  Launched in 2014 by the U.S. Department of Energy’s Better Buildings Alliance and the Institute for Market Transformation, Green Lease leaders sets the standard for what constitutes a green lease. The program provides guidance in leasing practices to advance mutually beneficial landlord-tenant relationships that lead to higher-performing buildings and healthier, more sustainable communities. Participants benefit from established guidelines and free support while developing their leases, as well as peer leadership recognition and substantial energy savings when leases have been implemented. Honorees are announced annually at the Department of Energy’s Better Buildings Conference .
