2. What if every single act of design and construction made the world a
better place?
imagine a building that is as efficient as a flower; a simple symbol for
the ideal built environment.

3. The Living Building Challenge (LBC) is a certification program that
defines the most advanced measure of sustainability
It is one of most rigorous performance standards in the industry, as it
requires net-zero energy, waste and water by every project.

4. Each facet of the Living Building Challenge is performance-based so
every building must measure for 12 consecutive months after
completion before receiving certification.
But when projects achieve this level of performance, they can claim to
be the ‘greenest’ anywhere and will serve as role models for future
construction.

5. THE SEVEN “PETALS”
The LBC is comprised of seven performance areas, or “Petals” –
Materials, Site, Water, Energy, Health, Equity, and Beauty.

6. 1. SITE PETAL
This petal clearly articulates where it is acceptable to build, how to
protect and restore a place once it has been developed and how to
encourage the creation of communities that are based on the
pedestrian and not the automobile.

7. 2. WATER PETAL
being a net-zero water facility and using 100% of storm water onsite
for internal water needs.
With the scarcity of potable water becoming a serious issue in many
countries, the LBC envisions a future whereby all forthcoming
buildings are configured based on carrying capacity of the site

8. 3. ENERGY PETAL
The Energy Petal requires all buildings to rely solely on renewable
forms of energy and operate year round in a pollution-free manner.
Therefore, the LBC requires all projects to have net-zero energy,
which can be attained by methods like photovoltaic solar panels,
natural daylighting and other systems.

9. 4. HEALTH PETAL
The intent of the Health Petal is to create robust, healthy spaces and
encourage a highly productive indoor environment.
For example, this Petal requires that every occupied interior space in
the building must have operable windows to provide fresh air and
daylight.

10. 5. MATERIALS PETAL
This Petal strives to have a successful materials economy that is non-
toxic.
This is one of the most challenging Petals of the LBC because every
project cannot contain any of the identified Red List materials,
including PVC and Formaldehyde.
Therefore, a detailed record of how each material is made by the
manufacturer must be kept and turned in before certification can be
achieved.

11. 6. EQUITY PETAL
The Equity Petal is focused on creating communities with equitable
access to all people regardless of physical abilities, age or
socioeconomic status.
One Imperative of this Petal is “Rights to Nature” that states that a
project “may not block access to, nor diminish the quality of, fresh
air, sunlight and natural waterways for any member of society or
adjacent developments.”

12. 7. BEAUTY PETAL
The purpose of this Petal is to design buildings that elevate our
spirits.
This Petal is based merely on genuine efforts to create aesthetically
pleasing designs, so there are currently no limitations or restrictions
for this Petal.
