Net Zero/Net Positive Carbon Building

A building is designed to be highly energy-efficient, with its remaining energy needs met entirely by renewable sources (preferably on-site, but off-site if necessary). This results in zero net carbon emissions annually. A Net Positive status is achieved when the renewable energy generation exceeds the building's total energy consumption.

Net Zero/Net Positive Carbon Building

Net Zero/Net Positive Water Building

This building type is designed to significantly reduce water use during both its construction and ongoing operations. It harvests, recycles, and reuses water such that the amount of water produced is equal to the amount consumed (Net Zero). A building is Net Positive when the water recycled or produced is greater than the total amount of water consumed.

Net Zero/Net Positive Water Building

Net Zero/Net Positive Waste Building

A building that manages its waste stream through reduction, reuse, and recovery of materials, ensuring that no solid waste is sent to a landfill over the course of a year, including both construction and operations, is considered Net Zero. It achieves Net Positive status if it processes waste from other sites, diverting it from landfill for productive reuse.

Net Zero/Net Positive Ecology Building

Achieving a Net Zero ecological impact means that a development on a greenfield site must maintain or restore the original pre-development ecological value of that site. For brownfield sites, existing developments, or greenfield sites, enhancing and improving the site's ecological features and biodiversity results in a Net Positive outcome.
