LBC CERTIFICATION FEATURES
What Is Living Building Challenge
Introduction of Living Building Challenge
The Living Building Challenge (LBC) is a green building certification system for new and existing buildings that aims to create structures that are net-zero energy, water, waste, and carbon emissions. It was developed by the International Living Future Institute (ILFI) and is considered to be one of the most rigorous green building standards in the world.
The LBC is based on seven performance categories, or “petals”: Place, Water, Energy, Health + Happiness, Materials, Equity, and Beauty. Each petal has a set of imperatives that must be met in order to achieve certification.
The LBC is a voluntary certification program, and there is no legal requirement to achieve it. However, many developers and owners choose to pursue LBC certification because it can help them to reduce their environmental impact, save money, and improve the health and well-being of their occupants.
The LBC is a relatively new certification program, and there are currently only a few hundred LBC-certified buildings in the world. However, the ILFI is actively working to promote the LBC and to increase the number of LBC-certified buildings.
The objectives of the LBC are to:
- Create buildings that are net-zero energy, water, waste, and carbon emissions.
- Improve the health and well-being of building occupants.
- Reduce the environmental impact of the built environment.
- Promote the use of sustainable materials and practices.
- Inspire others to build more sustainably.
The LBC is a challenging certification program, but it is also a valuable tool for developers and owners who are committed to creating buildings that are environmentally friendly and healthy for occupants.
Living Building Challenge Criteria and Certification Levels
Criteria:
The LBC is based on seven performance categories, or “petals”:
- Place: This petal focuses on the site of the building, and how it interacts with its surroundings. Imperatives in this petal include protecting and restoring native habitat, reducing stormwater runoff, and maximizing access to natural light and views.
- Water: This petal focuses on the water used in and around the building. Imperatives in this petal include using rainwater harvesting, onsite wastewater treatment, and low-flow fixtures.
- Energy: This petal focuses on the energy used to power the building. Imperatives in this petal include generating all of the building’s energy on-site, using renewable energy sources, and improving the energy efficiency of the building’s envelope and systems.
- Health + Happiness: This petal focuses on the health and well-being of the building’s occupants. Imperatives in this petal include providing good indoor air quality, natural ventilation, and access to daylight.
- Materials: This petal focuses on the materials used in the construction of the building. Imperatives in this petal include using recycled and sustainably sourced materials, and avoiding materials that are harmful to human health or the environment.
- Equity: This petal focuses on the equitable use of the building and its resources. Imperatives in this petal include ensuring that the building is accessible to all people and that it is affordable to operate and maintain.
- Beauty: This petal focuses on the aesthetic appeal of the building. Imperatives in this petal include creating a building that is visually appealing and that contributes to the surrounding community.
Certification Levels
There are three levels of LBC certification:
- Living: This is the highest level of certification, and it is awarded to buildings that meet all of the imperatives in all seven petals.
- Petal: This level of certification is awarded to buildings that meet all of the imperatives in one or more petals.
- Zero: This level of certification is awarded to buildings that meet all of the imperatives in the Energy and Water petals.
Benefits of Living Building Challenge Certification
There are many benefits to achieving LBC certification, including:
- Reduced environmental impact: LBC-certified buildings have a significantly lower environmental impact than conventional buildings. This includes lower greenhouse gas emissions, water consumption, and waste production.
- Increased energy and water savings: LBC-certified buildings typically save significant amounts of energy and water compared to conventional buildings. This can lead to lower operating costs and increased tenant satisfaction.
- Improved occupant health and well-being: LBC-certified buildings have been shown to improve occupant health and well-being. This is due to factors such as better indoor air quality, reduced noise levels, and increased access to natural light.
- Increased marketability and value: LBC-certified buildings are typically more marketable and valuable than conventional buildings. This is because they are seen as being more sustainable, healthy, and desirable.
Different Living Building Challenge Certifications
There are three different levels of LBC certification:
- Living: This is the highest level of certification, and it is awarded to buildings that meet all of the imperatives in all seven petals.
- Petal: This level of certification is awarded to buildings that meet all of the imperatives in one or more petals.
- Zero: This level of certification is awarded to buildings that meet all of the imperatives in the Energy and Water petals.
In addition to these three levels, there are also two special types of LBC certification:
- Core: This certification is awarded to buildings that meet all of the imperatives in the Energy and Water petals, as well as a set of additional imperatives that focus on equity, beauty, and inspiration.
- Emerging Market: This certification is awarded to buildings that meet all of the imperatives in the Energy and Water petals, as well as a set of additional imperatives that are tailored to the specific needs of emerging market countries.
To achieve LBC certification, a building must be designed, constructed, and operated in a way that meets the requirements of the LBC standard. The LBC standard is a comprehensive document that covers a wide range of topics, including energy efficiency, water conservation, indoor air quality, materials selection, and site planning.
The LBC is a challenging certification program, but it is also a valuable tool for developers and owners who are committed to creating buildings that are environmentally friendly and healthy for occupants.
Each of the above ratings are detailed systems of credits and prerequisites. The certification process is equally complex. Consult a green building specialist to determine which rating system your project should adopt to reap the maximum benefit out of the certification without paying extra for the same brand.
Living Building Challenge Registration and Rating Procedure
The registration procedure for the Living Building Challenge (LBC) rating system involves the following steps:

- Third-party Final Audit upon completion of 12-month performance period
- Recognition as a Registered, Ready, or Certified project
Project Team Formation:
The project team, which typically includes the owner/developer, architect, engineer, and other relevant professionals, is formed to collaborate on the LBC certification process.
Familiarization with LBC Requirements: The project team familiarizes themselves with the LBC requirements, which include the seven performance areas or “Petals” (Place, Water, Energy, Health & Happiness, Materials, Equity, and Beauty) and the 20 Imperatives within those Petals. They study the LBC documentation, guidelines, and resources to gain a comprehensive understanding of the program.
Preliminary Assessment:
The project team conducts a preliminary assessment to evaluate the feasibility of pursuing LBC certification. This assessment considers factors such as project scope, budget, and alignment with LBC goals and principles.
Letter of Intent: If the project team decides to proceed with LBC certification, they submit a Letter of Intent (LOI) to the International Living Future Institute (ILFI), the organization responsible for administering LBC. The LOI signifies the project’s commitment to pursuing LBC certification and initiates the registration process.
Registration Fee:
The project team pays the required registration fee, which varies based on the project size and type. The fee helps support the ongoing administration and maintenance of the LBC program.
Project Listing:
After the LOI and registration fee are received, the project is listed on the ILFI’s website as a registered LBC project, indicating its intent to pursue certification.
Documentation and Design Process: The project team develops the necessary documentation, including drawings, calculations, narratives, and specifications, to demonstrate compliance with the LBC Imperatives. They integrate LBC requirements into the design process and seek innovative strategies to meet the performance targets.
It’s important to note that the registration procedure for LBC is the first step in the certification process. Once registered, the project team proceeds with the documentation, design, and performance monitoring stages to meet the LBC requirements and ultimately achieve certification as a Living Building.
The Living Building Challenge (LBC) is a rigorous green building certification program that requires projects to meet a wide range of sustainability criteria. The LBC rating system is based on 10 performance areas, or Petals, which are:
