## anica Landreneau: pioneering Sustainable Design and the Future of Green Building
The landscape of sustainable architecture is rapidly evolving, driven by urgent climate concerns and a growing demand for healthier, more equitable built environments. At the forefront of this transformation is Anica Landreneau, Assoc. AIA, WELL AP, Fitwel, GGP, and now, a distinguished LEED Fellow. Her leadership at HOK,a global architecture firm,coupled with her influential roles in shaping industry standards and international policy,positions her as a key figure in the future of sustainable design. This article delves into Landreneau’s remarkable career, her contributions to the field, and the implications of her work for architects, developers, and anyone invested in a greener future.

Did you know? The building sector accounts for nearly 40% of global energy-related carbon emissions, making sustainable design practices more critical than ever.
A Career Dedicated to High-Performance Buildings
For over 18 years, Anica Landreneau has been a driving force at HOK, currently leading the firm’s global sustainable design practice since 2013.Based in the Washington, D.C.office, her influence extends far beyond the firm’s walls. Landreneau’s expertise encompasses a broad spectrum of sustainable building strategies, including high-performance design, decarbonization, electrification, and the crucial optimization of embodied carbon – the total greenhouse gas emissions associated with a building’s entire lifecycle.
Her commitment isn’t limited to new construction. Landreneau champions “deep green retrofits” – extensive renovations that dramatically improve the environmental performance of existing buildings - and the sensitive repositioning of historic structures. This holistic approach recognizes the meaningful environmental impact of the existing building stock, which represents a ample portion of the built environment. According to a recent report by the World green Building Council (October 2025), retrofitting existing buildings could reduce global carbon emissions by up to 60% by 2050.
Influencing Policy and Global standards
Landreneau’s impact extends beyond project-level design. She has consistently served in advisory roles, shaping building codes and industry standards. Her multiple terms on the District of Columbia Green and Energy Codes TAG, the Mayor’s Green Building Advisory Council, and as co-chair of the Building Energy Performance Standard Task Force demonstrate a dedication to systemic change.
Perhaps most notably, Landreneau chaired the USGBC LEED Steering Committee during the pivotal development and rollout of LEED v5.This latest iteration of the Leadership in Energy and Environmental Design rating system places a greater emphasis on performance-based metrics, carbon reduction, and the integration of health and wellbeing considerations. LEED v5, launched in late 2024, represents a significant shift towards a more holistic and data-driven approach to green building.
Her global engagement is equally impressive. Landreneau participated as a virtual delegate to COP28, the 2023 United Nations Climate Change Conference, and was a speaker and delegate to the inaugural United Nations Environment Program Buildings and Climate Global Forum. These platforms allowed her to contribute to international dialogues on building decarbonization and advocate for policies that accelerate the transition to a sustainable built environment.
Pro tip: When evaluating a building’s sustainability, don’t just look at energy efficiency. Consider the entire lifecycle, including material sourcing, construction processes, and end-of-life disposal.
Beyond Sustainability: Health, Wellbeing, and Equity
Landreneau’s vision for sustainable design extends beyond environmental considerations. She actively integrates principles of health, wellbeing, and equity into her work, recognizing that truly sustainable buildings must benefit both people and the planet. Her certifications in WELL AP and Fitwel demonstrate a commitment to creating spaces that promote occupant health and wellness.
This focus on building performance is increasingly important. A 2024 study by Harvard’s T.H. Chan School of Public Health found that improved indoor air quality can lead to a 15% increase in cognitive function and a 6% increase in productivity. Landreneau’s work aligns with this growing body of evidence, demonstrating that sustainable design is not just about reducing environmental impact, but also about enhancing the quality of life for building occupants.
