DETA ILED SUMM ARY OF CHANGE Changes from LEED 241 Welcome to LEED Beta Welcome to the next evolution of LEED for DESIGN and CONSTRUCTION ! Whether you are a seasoned LEED practitioner, or new to LEED, we encourage you to test out this bigger, stronger, bolder rating system for your buildings and to be a leader in shaping the future of BUILDING performance. There are four key goals that have guided our technical development process for the LEED BD+C rating system: ensure leadership increase achievability measure performance expand the market This version of LEED is the result of countless hours of effort from our volunteers and staff and we are confident that the rating system meets those goals.
6 -performance green buildings. For the last 18 years, various versions of LEED have pushed the global green BUILDING market forward progressively, with more than 93,000 registered and certified projects and more than 19 billion square feet of space worldwide. Regions and markets move at different paces, and we want to be sure we can meet the needs of everyone in the green BUILDING community. LEED represents a series of upgrades that will improve our standards, encourage leadership, and make our platform more user friendly, more accessibleand most importantlymore collaborative than ever before. requirement for adoption will come from our most valuable resource of allYOU! Highlights of LEED BD+C Integrative process The credit has a more balanced approach for project teams to understand, improve, and document both the process and outcomes of integrated DESIGN through a new documentation approach of a project team letter.
7 Project teams have greater flexibility to tell the story of their integrative process and earn more points for exemplary performance for new areas of interdisciplinary analysis at the frontier of green BUILDING , including social equity and public health. Projects can also demonstrate their thoughtful site selection decisions. Location and Transportation Reduced Parking Footprint recognizes variations in consumer behavior; preferred parking requirements are removed and three new credit options are added that reward projects for no off-street parking, providing carshare parking, or unbundling parking. Green Vehicles is renamed Electric Vehicles; the credit now refers to electric vehicles only and offers a new option rewarding the installation of electric vehicle infrastructure.
8 Bicycle Facilities requirements better accommodate diverse project-types; storage requirements are more representative of common site conditions and differing shower amounts were added for large-occupancy projects. Sustainable Sites Protect or Restore Habitat is more accessible for projects with a reduced restoration threshold, new soil and vegetation guidance, and lowered financial requirements. Rainwater Management requirements are more applicable and achievable; the credit features a reduced minimum percentile storm events and more guidance for zero-lot-line projects. Site Assessment is more relevant to international project teams; the US specific TR-55 standard is no longer required. Water Efficiency Updates to Indoor Water Use Reduction recognize variations in standard supply pressure across the globe and the European product labeling program.
9 Cooling Tower and process Water Use requirements are adjusted to be more relevant and achievable for projects; two new credit options incorporate a previous pilot credit and reward the use of alternative recycled water to meet process water demand. Core and Shell only: Points are re-allocated from Indoor Water Use Reduction to Outdoor Water Use Reduction and Cooling Tower and process Water Use to better align with Core and Shell scope of work. Energy and Atmosphere The referenced standard for energy performance is updated to ASHRAE ; projects are now required to demonstrate performance against two metrics: cost and greenhouse gas emissions. Optimize Energy Performance includes a new prescriptive option for individual systems optimization in BD+C.
10 Renewable Energy Production and Green Power and Carbon Offsets are combined into a new credit, Renewable Energy, to better address diverse methods of renewables procurement and evolving global renewables markets. Demand Response is updated to Grid Harmonization to recognize role of buildings in supporting grid-scale de-carbonization; the new credit option rewards technologies and strategies for BUILDING load flexibility and management. Materials and Resources To encourage greater uptake of all Materials and Resources credits, additional credit pathways and updated credit achievement thresholds are introduced for several credits, including BUILDING Life-Cycle Impact Reduction and BUILDING Product Disclosure and Optimization (BPDO) credits.
