However, not all green roofs and walls are created equal – the Green Infrastructure Foundation has developed the Living Architecture Performance Tool (LAPT) to certify that green roofs and walls are designed to achieve certain measurable and replicable performance benefits. By mandating the use of design, construction, and maintenance best practices, we can help unlock the ability of green roofs and walls as part of a climate solution.
The LAPT has a wide range of potential audiences and uses:
Designers and building owners can use it as a best practice tool or design guideline to optimize the breadth and depth of green roof and wall benefits. By demonstrating the linkages between benefits and encouraging holistic thinking, it is possible to obtain many additional benefits without significantly increasing cost or difficulty of many projects.
Policy makers can use the LAPT as a decision-support tool to optimize incentives, mandates, or grant programs – ensuring that policies that promote green roofs and walls actually achieve the intended performance benefits.
Manufacturers of green roof systems or other accessories can use the LAPT as a guide to design products that use more sustainable materials and that achieve higher levels of performance.
