Net Zero Bidding Requirements You Need to Know

Net zero construction bids require embodied carbon reporting, operational energy standards, and comprehensive documentation that traditional bids do not demand. Contractors must demonstrate compliance with specific material requirements and provide third-party verification of environmental performance.

Embodied carbon reporting forms the foundation of net zero bidding. The Buy Clean Act requires Environmental Product Declarations (EPDs) for all structural materials including steel, concrete, glass, and insulation used in federally funded projects. EPDs provide lifecycle greenhouse gas emissions data for specific products, allowing procurement officials to compare environmental impacts. Contractors must source materials with EPDs that meet maximum Global Warming Potential (GWP) thresholds established by the EPA. Steel products cannot exceed 2.2 tonnes CO2e per tonne, structural concrete cannot exceed 300 kg CO2e per cubic meter, and flat glass cannot exceed 750 kg CO2e per tonne.

Operational energy standards require buildings to generate as much renewable energy as they consume annually. Net zero energy buildings meet this requirement through ultra-efficient building envelopes, high-performance mechanical systems, and on-site renewable generation. Bids must include energy modeling demonstrating compliance with ASHRAE 90.1 Appendix G, showing at least 50% energy savings compared to baseline buildings. Contractors provide commissioning plans that verify systems meet design specifications.

Whole-building life cycle assessment (WBLCA) evaluates total environmental impact from material extraction through building operation and end-of-life. Federal projects over $10 million require WBLCA using the ATHENA Impact Estimator or Tally software. Assessment includes embodied carbon from materials, construction process emissions, operational energy, water use, and waste generation. Contractors demonstrate GWP reductions of at least 30% compared to code-compliant baseline buildings.

Buy Clean Act material requirements extend beyond structural components to all major building materials. Insulation products require EPDs showing compliance with GWP limits of 1.5 kg CO2e per R-value. Window assemblies need product-specific EPDs for glass, frames, and spacers. Mechanical equipment including HVAC systems, heat pumps, and water heaters require lifecycle emissions data. Contractors work with manufacturers to obtain compliant EPDs months before bid submission.

Documentation requirements for net zero bids exceed traditional construction projects. Bids include material sourcing plans identifying suppliers with compliant EPDs, energy modeling reports, commissioning plans, construction waste management plans targeting 75% diversion, and Indoor Air Quality management plans meeting LEED requirements. Third-party verification from organizations like the International Living Future Institute or U.S. Green Building Council provides credibility for performance claims.

Key Certifications for Net Zero Construction Bids

Green building certifications demonstrate contractor capability and meet mandatory requirements for many net zero projects. Understanding which certifications agencies require determines bidding eligibility.

LEED v5 certification, launched in 2024, represents the most widely required standard for federal and state projects.
