It isAi??is a philosophy, advocacy tool, and certification program that addresses development at all scales. It is comprised of seven performance areas called petals: Site, Water, Energy, Health, Materials, Equity, and Beauty. These are subdivided into a total of twenty Imperatives, each of which focuses on a specific sphere of influence.
Over 100 project teamsAi??are pursuing the Challenge. And certification is based on actual performance. Therefore, projects must be operational for at least 12 consecutive months prior to evaluation. Projects must meet all assigned Imperatives and have proven performance through at least 12 consecutive months of operation. To celebrate successes and to educate other efforts, project teams may earn a partial program certification by satisfying the requirements of a minimum of three categories, of which at least one must be water, energy or materials.
The Seven ai???Petalsai??? performance areas:
1. Site:
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. One of the Imperatives of the Site Petal is ai???Habitat Exchange,ai??? which requires that for each hectare of development, an equal amount of land away from the project site must be set aside in perpetuity.
2. Water:
The intent of this petal is to realign how people use water and redefine ai???wasteai??? in the built environment. 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 siteai??i??in other words, being a net-zero water facility and using 100% of storm water onsite for internal water needs.
3. Energy:
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.
4. Health:
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.
5. Materials:
This Petal strives to have a successful materials economy that is non-toxic, transparent and socially equitable. 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. Theyai??i??re also a lot of specifications on the type of timber that can be used and where the materials can be sourced.
6. Equity:
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 ai???Rights to Natureai??? that states that a project ai???may not block access to, nor diminish the quality of, fresh air, sunlight and natural waterways for any member of society or adjacent developments.ai???
7. Beauty:Ai??
The purpose of this Petal is to design buildings that elevate our spirits.Ai?? This Petal is based merely on genuine efforts to create aesthetically pleasing designs, so there are currently no limitations or restrictions for this Petal.
