Powering a Sustainable Future

At Co|Lab, HITT’s dedicated space for research and development (R&D) in Falls Church, Virginia, solar panels were added to the roof in December 2024. This is a crucial step towards achieving net zero certification for the sustainably designed, two-story mass timber building, which we aim to prove in 2025 and obtain in 2026. New materials and methodologies in sustainable construction such as solar will be key to pursuing net zero on HITT’s new headquarters building, set to deliver in 2027.

Leading the Way to Low Carbon Building

HITT is committed to reducing our carbon footprint through revised sustainability approaches and tangible strategies that align with industry best practices and emerging regulatory expectations. We are enhancing supplier engagement, expanding renewable energy initiatives, and aligning our reporting to global frameworks – all to make measurable progress towards a more sustainable built environment.

Implementing ECOPact on Data Centers

After successful testing, our mission critical teams implemented ECOPact, a low-carbon concrete mix with the potential to reshape industry standards, on data center jobsites nationwide in partnership with Holcim. ECOPact emits at least 30% less CO2 than standard concrete.

Smarter, Greener Building Materials

HITT’s R&D team actively explores next-generation materials that enhance sustainability, durability, and construction efficiency. In 2024, research focused on identifying alternatives to drywall and conventional insulation, addressing challenges related to embodied carbon, installation speed, and cost efficiency. To date, we’ve evaluated many low-carbon, bio-based materials with the potential to transform traditional wall assemblies, such as:

Engineered Bamboo Panels
Richlite Materials
Cork Insulation
Ekoa Bio-based Veneers

Optimizing Waste Reduction

HITT is shaping the future of construction waste management through data-driven tracking, advanced waste diversion strategies, and strategic partnerships. Our construction waste management policy, ensures all jobsites maximize material reuse, reduce landfill contributions, and improve material circularity.
