LEED V4

Materials Matter More

Materials Matter More

The materials section of the new LEED v4 rating system has been completely overhauled, with a big push towards market transformation and 3rd party certifications. The most drastic credit changes include the three new credits relating to Building Product Disclosure and Optimization:                             Across these three credits, Option 1 is based on the number of products in compliance, which means a threshold of 20+ different products from at least 5+ different manufacturers must be met. This option should be targeted early for easy credit achievement.  Option 2 is cost based, which makes it more difficult to grasp compliance until all product cost is tracked and documented. However, early material vetting is required, as well as proactive product selection strategies to maximize the number of credits a product can contribute towards.

ArchEcology’s 10th Anniversary

ArchEcology celebrated 10 years of certified green buildings with an anniversary event on September 15th held on the 40th floor of the Premiere on Pine building. Against a backdrop of spectacular views, participants learned what it takes to successfully certify a building in the newest LEED rating system – v4- which becomes mandatory for all new registrations on November 1, 2016. The presentation we gave, called How to Succeed in LEED v4, can be found on our Resources page. If you’d like to hear it from us and earn AIA continuing education credits, get in touch and we’ll schedule a lunch time session for your staff.

LEED v4 and Low Emitting Materials – Part Two … Wet Applied Products

LEED v4 and Low Emitting Materials – Part Two … Wet Applied Products

Previous versions of LEED have treated low emitting materials as 5 separate issues each worth 1pt. In LEED v4, all of these categories (plus a new one) have been combined into one credit called Low Emitting Materials that is worth only 3 possible points. Emissions testing has become the primary protocol for all products, but wet applied materials still carry the previous VOC content requirement like a cherry on top. While compliance may seem more simplified, perfect execution in at least 3 product categories is required which means the bar is set pretty high. You’ll need some proactive strategies. Assuring compliance for adhesives, sealants, paints or coatings before LEED v4 meant comparing grams per liter of VOCs in the product against VOC limits set by California regulations or GreenSeal standards. A project could provide product data with VOC content and receive a thumbs up or down on its use. If […]

LEED v4 and Low Emitting Materials – Part One … The Overview

LEED v4 and Low Emitting Materials – Part One … The Overview

Indoor air quality has always been a hallmark of LEED certification, and the new LEED v4 rating system raises the bar significantly when it comes to low emitting compliance. Previous versions of LEED have treated low emitting materials as 5 separate issues contained in 5 separate credits each worth 1pt. Adhesives and sealants comprised the first credit, followed by paints and coatings, flooring systems, composite wood and then systems furniture. Among the 5 credits were 3 different approaches to measuring low emissions based on product category – VOC content in grams per liter (g/l) for wet applied products, third party emissions testing for flooring and furniture, and no addition of urea formaldehyde to manufacturing of composite wood products. In v4, all of these issues have been combined into one credit called Low Emitting Materials that is worth a total of only 3 possible points. And the credit scope has grown […]
