1 GREEN BUILDING A NECESSARY STEP

2 WHO AM I? How I became involved in LEED What I am doing here? Where to next? LEED and on-site waste water? My Experience as a LEED consultant Why I chose to get involved in the green building industry A great place to start Multi-Disciplinary It is the future of our built environment and humanity!

14 7+ Billion Humans NEED ENERGY AGENDA

15 COAL POWER # IN GIGATONS 98g of CO 2 per 10^6 J of energy 2 40% of excess is absorbed 1 67g of CO 2 per 10^6 J of energy 2

16 History [3]

17 Green House Effect Green House Gases are another warming mechanism Earth has increased 1.1 F since the 20 th century [3] [2]

18 This degree of change has never been recorded in history3

19 August 1941 August 2011 Oceans levels have risen more than 17cm 4 7

20 0.5 F Warmer Waters over 100 years 5 Category 5 Storms have Doubled in the past 30 years 5 HURRICANE SANDY:

21 DRAUGHT 30% of agricultural land surface is at risk Water Wars California Today! Due to warming temperature and waters 250 million Africans will suffer [Hadley Centre for Climate Prediction and Research. 10] [10]

22 Warmer Temperatures Better breeding for mosquitoes Disease carried easier and further [11] Health Impacts Directly linked to Respiratory Illness BEIJING! [11]

23 Finite amount of resources AGENDA Generous enough to share them Unevenly dispersed No sense in wasting I. Un-Economic II. Inefficient III. Short sighted Consumption Rate

25 Sustainability?

26 Looking at a Cold Climate

27 Looking A Brief History at a Warm Lesson Climate

28 SOURCE USE 3 Times as costly to Produce instead of Reduce [12

29 THE BUILT ENVIRONMENT BUILDING CONSUMPTION GREEN BUILDING CONSUMPTION 13% lower maintenance costs 26% less energy usage 27% higher levels of occupant satisfaction 33% lower carbon dioxide (CO2) emissions [6]

30 THE TRIPLE BOTTOM LINE [6]

31 TODAY`S SOLUTION Leadership in Energy and Environmental Design (LEED) Standard for a Sustainable Building LEED is a Realistic First Step For Society LEED Incorporates Proven Existing Standards (Ex. FSC) Legitimate Committed Marketable LEED and YOU?

32 LEED Overview THE RATING SYSTEMS 100 possible points + 10 Bonus = 110 TOTAL 7 main Sustainable Categories to earn points

33 Categories Prerequisites - mandatory Credits - optional Award

34 Integrative Process Location and Transportation Sustainable Sites Water Efficiency Energy & Atmosphere Materials and Resources Indoor Environmental Quality Innovation in Design Regional Priority

35 LEED FOR THE DEVELOPER Low Initial Cost ~ 1% I. Green Does not mean Money II. Incentives High Return on Investment o Reduced operations cost due to water and energy efficiency Marketability

36 [5]

37 LEED FOR THE DEVELOPER

38 LEED FOR THE CONSUMER Supply and Demand Healthy and productive indoor environments Generation X Baby Boom Echo i. Education Implementation Increased Awareness ii. Cultural Change i. Garbage Limit ii. Earth Day iii. New job market It is our Future

39 LEED FOR THE CONSUMER

40 Green Building Incentive Strategies 1. Structural incentives low / no cost to the municipality Expedited review / permitting process Density and height bonuses 2. Financial incentives direct incentives to the developer Rainwater / waste water mitigation incentives (Toronto) Tax credits 3. Non-financial incentives - other Technical assistance Marketing assistance

43 LEED VERSION 2009 (v3) Release Date June 2009 Registration Deadline October 2016* Major Changes from V2 Treated wastewater can be reused or infiltrated/discharged 100 points across all rating systems LEED 2009 values = climate change #1 priority

44 LEED VERSION 4 (v4) Release Date November 2013 Registration Deadline N/A Major Changes from V3 Treated wastewater must be reused on site Not discharged offsite Rearrangement of credits and categories Stronger, more logical organization of credits

45 - LEED % of our municipal energy load is for pumping and treating wastewater

46 Water Efficiency LEED V4 CONSERVATION FIRST STRATEGY (Prerequisites) Alternative Water supplies second (Credits)

47 Water Efficiency The Baseline EPAct - U.S. Energy Policy Act of 1992 or US Uniform Plumbing code of 2006 Outdoor Baseline: Vegetation Type and Location during peak watering month

48 Water Efficiency Indoor/Outdoor Reduction (2009) Indoor Water Use Reduction Percentage Reduction Points (BD+C) 20% Prerequisite 30% 2 35% 3 40% 4 45% EP Outdoor Water Use Reduction Percentage Reduction Points (BD+C) 0% Prerequisite 50% 2 100% 4 1. Low flow fixtures 2. Waterless Urinals / Composting 3. ENERGY STAR rated appliances 4. Use Recycled grey water or rainwater for non potable needs 1. Adaptive/Native Plants 2. Xeriscaping 3. Efficient Irrigation 4. Demand Meters 5. Non-potable Irrigation 6. Gray Water Irrigation

49 Water Efficiency Indoor/Outdoor Reduction (v4) Indoor Water Use Reduction Percentage Reduction Points (BD+C) 20% Prerequisite 25% 1 30% 2 35% 3 40% 4 45% 5 50% 6 55% (EP) 7 1. Low flow fixtures 2.

Demand Meters 5. Non-potable Irrigation 6. Gray Water Irrigation

50 Innovative Wastewater Technologies (2 Points) Requirements Option 1 50% Reduction from EPAct 1992 or 2005 A. Conservation - OR B. Alternative Sources Option 2 Treat 50% of wastewater on-site To tertiary standards+ A. Used onsite - OR - B. Infiltrated by any means Option 1/2 Bonus point for 100%

51 Option 2 On-site Wastewater Treatment Steps 1. Integrative Process water goals 2. Schematic Design conservation vs. on-site 3. Early Design Size and Costs 4. Design and Development LEED Calcs 5. Construction Documents - specs 6. Construction - commission

52 On-site Wastewater Treatment Steps Considerations Environmental Benefits and Issues Reduce load on infrastructure On-site versus off-site treatment and supply Local/Regional codes for tertiary treatment Economic Benefits and Issues Capital Investment and ongoing Maintenance Savings from greywater Added construction costs (Ex. Dual plumbing lines) Regional incentives

53 On-site Wastewater Treatment Steps Synergies On-site Wastewater Treatment Steps Impacts

54 Accepted On-site Wastewater Treatment Wastewater must be treated to Tertiary Standards through: 1. Constructed Wetlands 2. Mechanical Recirculating Sand Bio Reactor system 3. Anaerobic Biological Treatment Reactors NOT ACCEPTED 1. Technologies which can contaminate the aquifer (Septic Tank)

55 Example - On-site Wastewater Treatment 1. Anaerobic Septic 2. Closed Aerobic Reactor 3. Open Aerobic Reactor 4. Constructed Wetland 5. Clean and non-potable water is the result

56 Case Study 1 - Oregon Health & Science University Building Type: Medical office and wellness building Building Size: 400,000 square feet Treatment system: Membrane Bio-Reactor (MBR) Capacity: 30,000 gallons per day Cost of wastewater treatment system: $1.2 million to build LEED Rating: LEED-NC Platinum

57 Case Study 1 - Oregon Health & Science University Facts GpD treated to highest standards for reuse (Oregon State) gallon fire-suppression tank to harvest 100% of rainwater 73% of water used in building is captured or reclaimed Water bills < $100 / month Rainwater, ground water and effluent is used for toilets, landscape irrigation, and the cooling tower

58 Case Study 2 The Solaire in New York City Building Type: Multi-unit residential Building Size: 357,000 square feet, 27-story Treatment system: ZENON Membrane Solutions from GE ] Treatment Plant Size: 700 sq. feet Capacity: 25,000 gallons per day LEED Rating: LEED-NC Gold

59 Case Study 2 The Solaire in New York City

60 Case Study 2 The Solaire in New York City Facts: 100% of wastewater is recycled and 5000 G provided to park No potable water used outdoors and 75% less in the building Roof retains 70% of rainwater

61 Case Study 3 Old Trail School, Bath, OH Living Machine Wastewater treatment system 1. Waste is piped from the independent school gallon primary tank fed by gravity fed sewer separates solids 3. Gray water flows into Horizontal Flow Wetland 4. Water pushed into Greenhouse into 2 tidal flow wetlands Empty and fill 5. Repeat steps two and three 17 times 6. Small vertical flow wetland 7. UV Chamber to kill bacteria 8. Pumped out to the tributary and into the Cuyahoga River
