Sustainability Standards in the Built Environment

Holistic Building Standards

These are the most recognized global standards. They cover everything from energy to water to materials.

  • LEED O+M (Operations & Maintenance): Building performance for existing buildings.
  • LEED BD+C / ID+C: The standards for new construction and interior fit-outs.
  • BREEAM (USA & International): A rigorous, science-based alternative to LEED in much of Europe.
  • DGNB (German Sustainable Building Council): The gold standard in Denmark and much of Europe.

Human-Centric Project Standards (Health & Wellness)

These focus on the “S” in ESG—the health, comfort, and productivity of the people inside.

  • Fitwel: A standard focused on evidence-based health design.
  • WELL Building Standard: A more technical, performance-verified health standard that complements LEED.
  • Reset: Focuses specifically on continuous data monitoring for indoor air quality (IAQ).

Performance & Carbon Standards (Technical Deep Dives)

When focusing on Decarbonization, these are essential for high-level strategy.

  • Living Building Challenge (LBC): The most rigorous “regenerative” standard (Energy, Water, and Waste Petals).
  • Passive House (PHI / PHIUS): The ultimate standard for building envelope performance and thermal comfort.
  • Zero Carbon (ILFI): A specific certification for projects that have neutralized both embodied and operational carbon.

Specialized Standards (Site & Waste)

These cover the areas outside the building envelope or specific lifecycle issues.

  • SITES: Like LEED for the landscape; focuses on ecosystem services and land development.
  • TRUE (Total Resource Use and Efficiency): The zero-waste certification; perfect for operations-focused consulting.
  • PEER: A standard for power system performance, focusing on reliability and resilience.
