11 Credit Categories - NEW - CHANGES - CHANGES - CHANGES - MAJOR CHANGES
Integrative process – new Sustainable sites – separated into location & transportation/sustainable sites Innovation – no changes Regional priority – no changes All changes in LEEDv4 are focused on improved performance. Focus on reporting performance, not yet guaranteeing performance (Living Building Challenge). Lots of small credit adjustments and we’ll give you some examples – and talk about what will most impact your work. - NO CHANGES - NO CHANGES

12 Question #1 What is one of the new categories in LEED v4?

13 Integrative Process New credit category.

14 ENCOURAGES EARLY ANALYSIS OF ENERGY AND WATER SYSTEMS TO INFORM DESIGN
v2009 DIDN’T EXIST v4 IPc1 NEW CREDIT ENCOURAGES EARLY ANALYSIS OF ENERGY AND WATER SYSTEMS TO INFORM DESIGN LEED has always fostered an integrated approach to design. Now projects can be rewarded for documenting that process. IPD, charrettes Involves entire project team to analyze opportunities early in design, before many choices have been made that could eliminate cost-effective options or concepts that if introduced down the line could not be achieved. All engineers, designers, owner, Cx agent, contractor if possible, other specialty team members – “Simple Box” energy model – energy, lighting, envelope; water budget

15 CHANGES IN SUSTAINABLE SITES
LOCATION & TRANSPORTATION v4 SUSTAINABLE SITES v4 SUSTAINABLE SITES v2009 Sustainable Sites has been reassembled to include a new credit rating category. The two types of site credits have been separated to provide a little more intuitiveness. SS category can now focus on project-specific site issues. 16 26 10

16 Location & Transportation
This new category focuses on the relationship between the project and the community where it is located. Credits are largely taken from the sustainable sites category of LEED2009. Services the Project provides, Services the community provides.

17 ENCOURAGES EARLY ANALYSIS OF ENERGY AND WATER SYSTEMS TO INFORM DESIGN
v2009 DIDN’T EXIST v4 LTc1 NEW CREDIT ENCOURAGES EARLY ANALYSIS OF ENERGY AND WATER SYSTEMS TO INFORM DESIGN New credit example: Outgrowth of “Site Selection” credit. Intent is to avoid inappropriate sites, reduce vehicle use, encourage physical activity. (walkability) Encourages projects to be located where community-level best practices have been established.

18 v2009 SSc4.1 v4 LTC5 CREDIT RENAMED FROM “ALTERNATIVE TRANSPORTATION – PUBLIC TRANSPORTATION ACCESS” MULTIPLE THRESHOLDS TO REWARD VARYING TRANSIT SERVICE LEVELS .25mi Revised Credit Example: Minimum trip counts for buses, transit, rideshare stops on both weekdays and weekends., More points for more trips. Pedestrian pathway instead of “as the bird flies”. RADIUS = .25mi WALKABLE DISTANCE = .25mi

19 v2009 Sc4.3 v4 LTc8 Credit renamed from “alternative transportation – low emitting and fuel efficient vehicles” The familiar preferred parking requirement plus: An additional 2% of parking spaces must have refueling stations-electric vehicle charging or liquid, gas, or battery facilities

20 Sustainable Sites

21 NEW RENAMED / REORGANIZED
Focus is on the project site and how it benefits the immediate ecosystem. RENAMED / REORGANIZED

22 ENCOURAGES EARLY ANALYSIS OF SITE CONDITIONS TO INFORM DESIGN
v2009 DIDN’T EXIST v4 SSc1 NEW CREDIT ENCOURAGES EARLY ANALYSIS OF SITE CONDITIONS TO INFORM DESIGN New credit example: Typography, hydrology, climate, vegetation, soils, human use, human health effects Examples: rainwater collection opportunities (hydrology) temperature ranges, solar exposure (climate)

23 v2009 SSc7.1 v4 SSc4 v2009 SSc7.2 COMBINATION OF “HEAT ISLAND EFFECT – NONROOF” AND “HEAT ISLAND EFFECT – ROOF” UPDATED Revised credit example: Combined; higher shading and solar reflective index thresholds. Why are heat islands important? (next slide). Details: Raised the minimum solar reflective index values + 3 year aged SRI values (low slope 78 > 82, aged 64; high slope 29 > 39, aged 32) Changed paving materials metric to solar reflectance (sr) Increased threshold for parking spaces under cover – 50% > 75% COMPARE TO T : low slope aged 75; high slope aged 16.

24 SACRAMENTO Neil—Importance of reducing heat islands - design day temperatures to include heat island effect

25 INCLUDED EXTERIOR SIGNAGE REQUIREMENTS ADDED EXEMPTIONS
v2009 SSc8 v4 SSc6 INCLUDED THE BUG RATING METHODOLOGY AS A PRESCRIPTIVE WAY TO MEET THE EXTERIOR LIGHTING REQUIREMENTS ADDED LIGHTING ZONE 0 INCLUDED EXTERIOR SIGNAGE REQUIREMENTS ADDED EXEMPTIONS Prescriptive per-fixture method: BUG = backlight, uplight and glare Performance Calculation = photometrics– similar to LEED2009 Intent: Reduce glare, light trespass, and skyglow, improve nightime visibility Effect: Worst offender: gas station – forget headlights Large Energy Impact

27 Question #2 What importance does the heat island effect have on mechanical systems and architectural design?

28 Water Efficiency

29 NEW

30 No irrigation beyond 2-yr. maximum establishment period, OR
30% minimum irrigation water reduction for peak watering month. Building Water Use 20% minimum indoor water reduction. New fixtures: Watersense labeled Appliance and Process Water Use Standards for Appliances – ENERGY STAR, CEE Standards for Processes: No once-through potable water cooling for appliances that reject heat Cooling Towers and Evap. Condensers: Equip with additional meters and alarms to reduce water use First time a pre req in water Permanent water meters for potable water – manual or automated Share 5 years of data with USGBC

31 Templates now combine matching prerequisites and credits

32 +1 point: Increase treatment OR use 20% recycled non-potable water
Conduct a one-time potable water analysis in cooling towers and evaporative condensers to measure concentrations of 4 minerals + conductivity 1 point: Limit cooling tower cycles to avoid exceeding maximum concentration levels. +1 point: Increase treatment OR use 20% recycled non-potable water Permanent Water Meters for Two or More Subsystems: Irrigation Indoor plumbing fixtures Domestic hot water Large boilers Reclaimed water Other process water

33 Question #3 Why is it important to distinguish between potable and non-potable water use? More than 50% of fresh water in CA goes to irrigation

34 Energy & Atmosphere

35 NEW NEW

36 Addition of exterior closures in OPR and BOD documents
Reference Guides: ASHRAE Guidance and ASHRAE Guideline for HVAC&R Systems NIBS Guideline for exterior closures Addition of exterior closures in OPR and BOD documents Can be reviewed by member of design or construction team Creation of Facilities Maintenance Plan

43 Question #4 What is the biggest change in Energy & Atmosphere when compared to LEED 2009?

44 Materials & Resources Category with the most changes – LEEDv4 introduces entirely new approaches to these credits. Elephant in the room, main source of LEEDv4 controversy.

45 NEW The big change center around the “building product disclosure and optimization” credits, or “Product transparency” credits: Vs LEED2009 single-attribute credits we are used to – recycled content, rapidly renewable, regional, certified wood. Example: “This product is sustainable because it has recycled content.” What if it also has unhealthy ingredients in it? Where did old MR credits go? Embedded within these new credits, with some changes. Let’s

46 Option 1: Divert 50% and three material streams (1 point)
New: Now can Include wood waste converted to fuel (bio-fuel) in the calculations Waste-to-energy systems may be considered waste diversion if listed directives are followed Option 1: Divert 50% and three material streams (1 point) Option 2: Divert 75% and four material streams (2 points) Option 3: Reduction of total waste material (2 points) Do not generate more than 2.5 pounds of construction waste per square foot of the building's floor area. Option 3: Why? 2.5 pounds per bldg. s.f. assumed normal in early LEED – not so!

47 Chico Gateway Museum: 114.72 tons generated = 229,440 pounds
9,698 s.f. 23.68 psf generated! (68% diverted) Fausel Professional Building: tons generated = 316,480 pounds 18,637 s.f. 16.98 psf generated! (82% diverted) NRF Production Support Complex: tons generated = 606,800 pounds 89,964 s.f. 6.74 psf generated! (65.5% diverted) Products: Packaging, minimizing waste Gateway: Small project, normal amount of sitework Fausel: Medium project, significant amount of sitework PSC: Large project, small amount of sitework How to help: Packaging – reusable, recyclable

48 BUILDING PRODUCT DISCLOSURE AND OPTIMIZATION CREDITS: ALPHABET SOUP
LCAs EPDs HPDs C2C Athena Impact Estimator Lots of new acronyms, can be overwhelming. -Let’s provide some definitions.

49 Life Cycle Assessment (LCA)
ALPHABET SOUP Life Cycle Assessment (LCA) Environmental Product Declaration (EPD): Environmental Report of product performance based on Life Cycle Assessment Lots of acronyms. Let’s look first at Lifecycle Impact Reduction: LCAs – cradle to grave or cradle to cradle Lifecycle Impacts can be reduced by: Use of historic or abandoned buildings Reuse and salvage of building materials Shorter transportation distances (“REGIONAL MATERIALS”) Whole building LCA – 10% better design case than base case EPDs: Certified 3rd party report of the environmental impacts from extraction, manufacturing, use, and disposal or reuse of a product. Manufacturers will be asked to provide these to designers and contractors. Provides designers reliable data to make informed product choices about embodied carbon, energy, and water. Example: Reduces individual designer research such as gypsum board – recycled vs manufactured close by – which is better? Example: Bamboo – transportation distance? I see this change to LEEDv4 making my life easier as a specifier – helps centralize the information I am looking for to evaluate products. Image: Edge Environment

50 Step 1: Disclosure of impacts Step 2: Optimization of impacts
PRODUCT TRANSPARENCY Step 1: Disclosure of impacts Step 2: Optimization of impacts LEEDv4 new/reorganized material credits have a first point for the simple disclosure of life cycle costs and chemicals of concern, and climate change potential, and additional points for optimization of those materials – using materials that have a smaller life cycle cost, contain fewer or no chemicals of concern, and/or “less bad” or “good” climate change potential. - Image: GreenScreen

51 Products sourced within 100 miles are valued at 200% of their cost
Option 1: Environmental Product Declaration - Disclosure Use at least 20 different products from at least 5 different manufacturers that meet one of the disclosure criteria Option 2: Multi-Attribute Optimization - Optimization 50% of products by cost reduce: Global warming potential Depletion of the ozone layer Acidification of land and water sources Eutrophication (nitrogen, phosphate) Formulation of tropospheric ozone Depletion of nonrenewable energy resources Intent: To encourage adaptive reuse and optimize the environmental performance of products and materials. One point for disclosure – products that have LCA’s. Another point for optimization - choosing products that have improved environmental impact than industry average. Example: closed-loop recycling program. Here you see the old “Regional Materials” credit tightened and within another credit. Products sourced within 100 miles are valued at 200% of their cost

52 Mechanical engineers: Your architect is going to be requiring these for the insulation you specify around your ducts or below your rooftop HVAC units…. Plumbing engineers: For your piping….. (PVC?)

53 Health Product Declaration (HPD):
ALPHABET SOUP Health Product Declaration (HPD): “An impartial tool for the accurate reporting of product contents and each ingredient’s relationship to the bigger picture of human and ecological health.” -The HPD Collaborative HPDs provide a disclosure of the potential chemicals of concern in products by comparing product ingredients to a wide variety of “hazard” lists published by government authorities and scientific associations. It is ONE OF THE STANDARDS to meet the credit requirements for meeting the material ingredient credit we’ll look at next.

54 “RED LIST” The subject is complex – we are not chemists. How do we choose healthy materials? Chemistry was my worst subject…

55 Option 1 – Material Ingredient Reporting (1 point)
Use at least 20 different products from at least 5 different manufacturers that use any of the following programs to demonstrate the chemical inventory of the product to at least 0.1% (1000 ppm): Manufacturer Inventory Health Product Declaration Cradle to Cradle USGBC approved program Option 2 – Material Ingredient Optimization (1 point) Use products that document their material ingredient optimization using the paths below for at least 25%, by cost, of the total value of permanently installed products in the project: GreenScreen v1.2 Benchmark. Cradle to Cradle Certified (if Platinum can use 150% of cost) International Alternative Compliance Path – REACH Optimization Option 3 – Product Manufacturer Supply Chain Optimization Intent: To encourage the use of products and materials for which chemical content information is available and that have environmentally, economically, and socially preferable life-cycle impacts. The material ingredient, or “product transparency” reports are similar to a nutrition label at the grocery store. Center of controversy over LEEDv4: Health and materials: Battle between USGBC and some chemical manufacturers (American Chemistry Council) who tried to ban LEED because they don’t want the public to know what is in their products: Convinced some state governors. Federal Standards now: LEED or Green Globes Why should you care? – Right to know what chemicals are in our buildings that we spend 90 of our lives in, like what food we put in our bodies. Building health is important to everyone: -”My child has asthma….” -”My mother has sick building syndrome and is in a hospital that is making her worse instead of better….”

56 PRODUCT TRANSPARENCY INITIATIVES HDR Perkins + Will
Architectural Nexus U.S. Chamber of Commerce: July 2013: “Skanska announced our resignation from the U.S. Chamber of Commerce to protest the Chamber’s backing of a chemical industry-led initiative (amendment in 2013 Senate Bill 761) to effectively ban the future use of LEED for government buildings. “ Patty: Describe Nexus commitment and initiative – to creating healthy buildings. Neil: Describe Glumac commitment Information = Impact

57 Question #5 What is the difference between an environmental product declaration and a health product declaration?
