3 Architectural Nexus is a Registered Provider with The American Institute of Architects Continuing Education Systems (AIA/CES). Credits(s) earned on completion of this program will be reported to AIA/CES for AIA member. Certificates of Completion for both AIA members and non-AIA members are available upon request. This program is registered with AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

4 Learning Objectives: 1. Understand how LEED is developing with recent changes proposed in LEED v4 2. Understand how LEED v4 restructures credits 3. Review new LEED categories 4. Understand how the new Materials and Resources credits impact industry standards

5 GBCI Credit This presentation is pre-approved for one hour of LEED-specific continuing education by the Green Building Certification Institute. Everyone will need to self report at gbci.org under 'my credentials.gbci.org Leave your at the sign-in table for certificates.

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 Permanent water meters for potable water – manual or automated Share 5 years of data with USGBC

31

32 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?

34

35 NEW

36 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

37 ASHRAE More efficient Baseline Must meet before counting Renewable Energy Option 1: Energy Simulation 5% NC, 3% MR, 2% CS Retail must include process load equipment Option 2: Prescriptive Compliance: ASHRAE 50% Energy Design Guide Option 3: Prescriptive Compliance: Advanced Buildings Core Performance Guide Less then 100,000 SF Not Healthcare Data Centers must be 5% over baseline by energy cost and IT equipment cost Includes cooling units for computer and data rooms and critical equipment 2% of 5% energy savings through building power cooling infrastructure Include process loads from unregulated load and IT equipment load

38 Meters for five years Share with USGBC Path 1: is similar to LEED 2009 Path 2: Additional point by developing monitoring-based procedures and identify measurement points to evaluate performance of systems AND/ OR (2pts) Option 2: Envelope Commissioning Data Centers that select Path 2 Option 1 must: Review of OPR and BOD before 50% CDs Back check review comments and Review at 95% Larger projects review at start of DDs, before 50% CDs, and at 100%
