ASHRAE Global Headquarters

Atlanta, Georgia
A Deep-Green Net Zero Energy Retrofit Accomplished on a Tight Budget

ASHRAE’s new global headquarters demonstrates how an old, existing three-story building built in the 1970’s can be transformed into a high-performing, net-zero ready, multi-use facility in a cost-effective way that offers a framework for others to replicate. The 66,700 square foot office building was completely renovated and retrofitted using innovative technologies, systems, integrated design, and sustainable materials to reduce energy use, water consumption, and carbon footprint. The new building pursuing Net Zero certification, exceeds all of ASHRAE’s own energy and indoor environmental standards to achieve a high-performing and environmentally sustainable building with inviting spaces to work, adaptable educational places, and shared communal areas for gathering. McLennan Design lead the project with Houser Walker Architects as partner.

Reusing entire structures and retrofitting them to be both super efficient and then powered by renewables is the ultimate solution, as it addresses both operational and embodied carbon impacts.

The goal of the project was to produce one of the most energy efficient buildings in the south, and to exhibit advanced mechanical and electrical solutions as a demonstration of high performance design.

Healthy indoor spaces filled with daylight
The goal of the project was to pursue a design that minimized the environmental footprint on the site, while trying to optimize the use of the building’s roof and adjacent areas that did not involve land disturbance or removal of established trees.

As a center of education and awareness of energy efficiency practices, we believe this project helps people understand how to design for specific climates and ecosystems and to work with what they have. Not everyone can afford the design of expensive new construction- this project is an example of a cost effective, deep retrofit that is needed in cities all over the globe.  More resilience in our communities emerges by re-using and upgrading existing  infrastructure, rather than continuing to sprawl outwards with new buildings and new systems.
