Living Building Challenge Resources

The Living Building Challenge Standard

The Living Building Challenge Standard is the core document that project teams use to guide a path toward certification. Download the pdf to learn more about the regenerative design framework and program requirements.

Documentation Requirements

Project teams should refer to this document periodically throughout every phase of their project, from predesign through the end of the performance period, in order to prepare for the audit.

Living Building Challenge 3.1 Guidance Handbook

This Early Guidance Handbook is a free addition to the LBC Petal Handbook series, a critical resource for project teams pursuing the Living Building Challenge 3.1. There is one Petal Handbook for each of the seven Petals, and those handbooks define the requirements for each Petal as of their date of issue.

Dive into the details of the Living Building Challenge’s seven performance areas. The Petal Handbooks include critical information for projects pursuing every certification type.

Each Petal-specific handbook includes:

  • Technical guidance
  • Clarifications and exceptions
  • Terms and definitions

The Dialogue

Registered project teams have access to the Dialogue, which is an online platform for teams to request precedent setting clarifications and exceptions. These rulings inform the ongoing evolution of the LBC standard and the compliance of proposed strategies for meeting LBC requirements. Dialogue access is through each project’s LBC dashboard. If you experience difficulty accessing or posting to the Dialogue, please contact

Materials Databases

Declare Product Database

ILFI’s Declare database hosts detailed information on all materials and products that have registered with the Declare program.

Materials Petal Database

Healthy Urban Places is a third-party website with information about various building materials, listed by CSI division.

This resource can be a starting point for teams pursuing the Materials Petal of the Living Building Challenge.

Important: Materials in this database do not automatically meet the requirements of the Living Building Challenge. Project teams must still vet each material and gather their own documentation.

The Red List

The Red List contains twenty-two classes of chemicals. Each chemical class contains a multitude of individual chemicals, identified by their Chemical Abstract Services Registry Number, or CAS RN. Taken together, these classes comprise nearly eight hundred individual ingredients.

Use this resource to show manufacturers precisely which ingredients are prohibited from inclusion in Living Buildings.

Sample Division 01 Specifications

ILFI has drafted sample Division 01 specifications for project teams to reference when including the Materials Petal and Health & Happiness Petal requirements in their Construction Documents. The use of these sample specifications is not required and the information should be incorporated into the Construction Documents at the project team’s discretion. These sections are intended to serve as a guide and should be modified to meet the specific needs of the project. ILFI is collecting project team feedback using the published Spec Resource Feedback Form and will incorporate feedback into the final LBC Specification Resource package.

+ Section 01 74 19-Construction Waste Management

+ Section 01 81 13-Sustainable Design Requirements

FSC Sourcing Guide

The Forest Stewardship Council (FSC) Sourcing Guide provides an overview of the Living Building Challenge requirements for wood and includes sourcing tips.

Sample Materials Lists

Several project teams have made their materials lists publicly available. Project teams must still conduct their own research to ensure that the materials from these lists comply with the current materials requirements.

Important: We don’t guarantee the compliance of listed products: these lists have not been reviewed by ILFI and are not sufficient for materials documentation.

Biophilic Exploration Guidebook

ILFI has developed this guidebook to help Living Building Challenge project teams develop more biophilic projects and comply with the requirements and intent of Imperative 09 – Biophilic Environment. The guidebook includes a general overview, as well as recommended topics, content and tips.

Charrette Facilitation

We’re here to help you find feasible solutions for their Living Building Challenge projects. Charrettes are optional kick-off meetings to help your team define fundamental and strategic goals.

We design the agenda, facilitate the session, and provide a follow-up summary.

Design Development Guidance

Spends a day with ILFI staff to discuss how your project accounts for each Imperative of the Living Building Challenge. Following a review of the project documents, we will issue a report outlining our guidance that will help your team achieve certification. Guidance can be focused on the Imperatives within a single Petal, select Petals, or all seven Petals of the Living Building Challenge.

In-House Workshops

Customized training is available as an optional service for organizations and project teams to ensure that project team members have a shared understanding of the Living Building Challenge or particular Petal area. The most common workshop requested is a full-day introduction to Living Building Challenge. During these workshops, we’ll discuss contextual information such as development patterns and density, and regulatory, financial, behavioral and technological barriers and incentives. We also offer customized technical assistance for teams working on projects currently in the design phase.

Product Consulting

We support manufacturers as they embrace transparency and investigate how their products meet the Living Building Challenge requirements. We’ll examine your manufacturing process, supply chain, and product performance requirements in order to identify Red List chemicals and possible alternatives.

Green Star-Design & As Built + Living Building Challenge 3.1

The Green Building Council of Australia and the International Living Future Institute have agreed to work collaboratively to promote the design, construction and operations of positive and restorative buildings in Australia. This document provides assistance for new buildings seeking to obtain both a certified Green Star – Design & As Built rating and a Living Building Challenge Certified rating.

Living Building Challenge 3.1 & WELL Building Standard

The International Living Future Institute (ILFI) and the International WELL Building Institute (IWBI), have agreed to work collaboratively to promote the design, construction and operations of healthy and restorative buildings. The two organizations will work together to identify opportunities to align the two rating systems, coordinate events and education offerings, and promote building practices that significantly raise the standard of what green buildings should be.
