Why we do this… 6

What is L.E.E.D.? 7 Leadership in Energy & Environmental Design Framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions

Brief Introduction 8 A system to define and measure “green buildings” Started with Version 1.0 (1998) - now 3.0 (2009) Voluntary (currently mandatory for certain state funding) Consensus-based Market-driven

LEED Building Categories 9 4 Levels of Certification

LEED Point System 10 Credits accumulate to determine rating Certified40-49 Points Silver50-59 Points Gold60-79 Points Platinum Points Must meet pre-requisite credits

What LEED measures 11 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Benefits to LEED process 12 Integrative Design Process (I.D.P) Brings all parties together to create a holistic design

Case Study – ALF Voorhees, NJ 13 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality

How We Got Started 18 Meet for collective goal setting (I.D.P.) Review LEED objectives –LEED for Healthcare vs. LEED for New Construction Set certification target Schedule milestones in process Discuss factors affecting target certification

LEED-HC (Healthcare) 19 Designated Medical Facilities Inpatient and Outpatient Facilities Looks at CCRCs & Operations New 2011 LEED-NC (New Construction) Office, Warehouse or Residential New Construction/ Major Renovations Around since 1993 Which way to go…

What LEED-HC looks at… 20 Minimize potable water use for medical equipment cooling Measure water serving –Laboratories –Sterile Department –Surgical Suite –Steam Boilers Conform to ASHRAE 170

21 SCORECARD TOTAL POINTS

22 TOTAL POINTS SCORECARD

What LEED measures… 23 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Site Development – Maximize Open Space – Respect Existing Wetlands – Minimum Parking Capacity – Re-purpose an existing site Sustainable Sites 24

25 Site Plan Maximize open space Natural Habitat Views to ball field Community pathway and Retail access Court Buffer

Alternative Transportation – Public Transportation – Bicycle Storage / Changing Room – Fuel Efficient Vehicle Parking – Minimum Parking Capacity Sustainable Sites 26

What LEED measures 27 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Water Efficiency 28 Water Use Reduction – 30% –Maintained aesthetic while increasing efficiency –Considered multiple fixtures 165 Toilets 170 Faucets 115 Showers 4 Washing Machines –ROI (months)

Water Efficiency GPM VS. 2.2 GPM 1.5 GPM VS. 2.0 GPM 1.28 GPF VS. 1.6 GPF

What LEED measures 30 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Goals from I.D.P. – Reduce energy load without compromising Comfort Aesthetic Amenities – Minimize first costs – Reduce overall operating costs – Be better than ASHRAE by 10% Energy & Atmosphere 31

The Lighting Discussion –Decorative incandescent fixtures needed to remain –Energy code still must be met –Most Energy Efficient option investigated for general lighting LED vs. Fluorescent The ROI Energy & Atmosphere 32

33 LED vs. Fluorescent ROI

34

The HVAC Discussion –Electric PTAC’s used for residents in past –PTAC’s already ruled out prior to pursuing LEED –Reviewed options with Owner Energy & Atmosphere 35

What we compared… –PTACs –2-Pipe Fan Coil Units –4-Pipe Fan Coil Units –Variable Refrigerant Systems –Air-cooled chillers/Water-cooled chillers –Boiler Plant Energy & Atmosphere 36

Energy & Atmosphere 37 Final Decisions –4-Pipe Fan Coil Units Individual residents choose heating vs. cooling Versatile and flexible Increased resident comfort –Air-cooled Chiller with Glycol No compressor noise in rooms –Dedicated Outdoor Air System Pressurize the building Eliminate drafts through PTACs and windows

Energy & Atmosphere 38 Creating a comparison: Energy Modeling –ASHRAE 90.1 Appendix G Provide constraints for energy model Provides assumptions for energy model Provides data for baseline building –From the Architect Develop Baseline Building Use the ASHRAE 90.1 minimum prescriptive reqs.

Energy & Atmosphere 39 How Energy Modeling results are compared –Develop Baseline Model Rotate it 90 o / Run Energy model Rotate it 180 o / Run Energy model Rotate it 270 o / Run Energy model –Compare models to proposed building

40 Baseline Energy Costs ASHRAE Modeled Baseline Cost

41 Baseline Energy Costs Proposed Building Energy Costs

42 36% Energy Savings 25% Energy Cost Savings Savings

Energy & Atmosphere 43 Energy efficiency is an ongoing process –Building Commissioning is included –Maintenance of building systems ensures continued, appropriate operations –Integration of direct digital control system monitors and controls systems

What LEED measures 44 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Recycling –Construction Waste Management Plan –Recycling Programs by Facility Materials Selections –Recycled Content –Regionally Manufactured/Extracted No VOCs Materials + Sources 45

What LEED measures 47 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Construction practices: IAQ Management Plan Materials selection (Low VOCs) Ventilation increases - Energy Recovery System IEQ (Indoor Environmental Quality) 48

What LEED measures 49 Sustainable Sites Water Efficiency Energy & Atmosphere Material + Sources Indoor Environmental Quality Innovation in Design

Use anticipated credits from LEED-HC – Connection to Natural World – Water Use Reduction: Food Waste Systems Use credits from other Rating Systems –LEED-CI: Energy Star Appliances –LEED-EB: Green Cleaning Policy Innovation in Design 50

Big Picture – Does it Cost More? 54 3% more for a better HVAC system ROI +/-7 years 1% more for fees (USGBC, architect, engineer, contractor, etc.) No longer premium for building materials

Conclusions 55 Start early in design process Employ Integrated Design Process Establish Sustainability goals Assist team in understanding the process Understand green building is good design
