13. Standard 100 Revision Flow Chart Compliance Requirements Section 4 Standard 100 Compliance Does Building Meet Energy Target? Sect. 7 NO YES Is there a Target for Building type? Section 7 YES NO Standard 100 Seek Compliance Implement Mandatory Operations and Maintenance, Section 6 Complete Compliance Forms for Buildings with Targets Section 4 Complete Compliance Forms for Buildings w/o Targets Section 4 Verify Energy Savings Section 9 Prioritize, Implement & Commission EEMs Section 9 Verify Energy Savings Section 9 Prioritize, Implement & Commission EEMs Section 9 Conduct Energy Audit Section 8 Conduct Energy Audit Section 8 Identify Building Type, Climate Zone and Collect Energy Use Data, Section 7 Implement Mandatory Energy Management Program, Section 5
22. Create O&M Plan Identify Systems and Equipment Section 6 Operations & Maintenance O&M Plan Documented Yes No Section 6: Operations and Maintenance Flow Chart Maintenance Due? Go to section 4 Compliance Domestic hot water Refrigeration Controls HVAC Lighting Other Systems No Implement Plan Yes Due Last System? Yes No Done Done Done Due Due Due Record Work performed Repair, Replace Perform O&M Repair Or O&M Justification Replace This section is for all sub categories Record Work performed Yes Precede to Next System Yes Yes Done Done Done Due Due
26. On-Site Energy Production On-Site Solar Electric Energy On-Site Solar Thermal Energy On-Site Thermal Waste Stream Energy Recovery Energy Delivered to Site Electric Power to site Gas/Oil to site Combined Heat & Power (CHP) Building Energy Use on-site On-Site Co-Gen Energy Produced Net energy use concept Excess Solar Thermal from site sold to another building Captured waste heat sold to another building Excess Electric Energy from site sold to Grid
36. Draft Commercial and Residential Building Energy Performance Benchmarks Based on Integrated Development Approach (kBtu/ft2-yr) Note: Results shown for 11 commercial building types due to limited space. Zonal EUI = CBECS/RECS National Median EUI x Zonal Ratio

39. Collect Building Energy Use Data Meet Energy Target? Go to Section 4 Compliance Generate Target Building Use Type? CBECS = 48 RECS = 5 Sub Types Apply Multiplier for Baseline Bldg Data Section 7 - Energy Survey & Target Requirements Flow Chart NO Yes Go to Section 8 Audits Calculate Percent of the Total Building Area for EACH Building Use Type Calculate BLENDED Building Use Mixed Use Define Each Building Area for Building Use Type Single Use Does Building have benchmark Target? NO Go to Section 8 Audits Yes Calculate Building Baseline
43. Section 8 - Energy Audit Requirements Flow Chart Building With Target That Has Not Been Met Building Without Target Perform Level II Analysis (Cost-cap at 10% of Annual Energy Cost) Building Audited within past 3 years? … Section 9 No Yes STD 100 Select EEM’s & Optimize Bundle to Reduce Energy Usage (cost effectiveness criteria for 5 year simple payback) STD 100 Perform Level I Analysis Bundle EEM’s to Reduce Energy Usage Meet Target? Perform Level II Energy Analysis … Section 9 No Yes Building Audited within past 3 years? No Yes Calculate Energy Use (on paper) & Compare with Building Target
44. Sections 9 Implementation and Verification Requirements

47. Section 9 Implementation Requirements Flow Chart STD 100 Develop Implementation Plan Use 1 year utility data (post-retrofit) to develop new EUI Energy Use Less than Building Target … Section 4 Compliance forms No No Yes Implement and commission EEM’s per plan Yes Verification Does Building have Target? … Section 7 Audit
-purpose and scope is the same Big expansion in the definitions Compliance: some apparent enhancements Added and Energy Management Program -Modified O&M -Added Targets Enhanced Energy Audit requirements -Added implementation requirements
-Timeline…could be extended since need to monitor, verify , and potentially re-audit and retest -Compliance Process- flow chart provided, and timeline, and forms Must create an energy management program and O&M plan -Must benchmark and meet or beat benchmark
-just note that appears following good practice
-review this
-note the sources and challenges
-fly over next few slides
-they appear to have chosen option 3, which was a blend with some modeling
-multiple buildings must have a plan for coordinating such measures and an EIU on a campus basis
- The question of commissioning is being proposed in the new standard, but was not shown in detail in the public review draft -With Targets: EUI’s shall be monitored for one full years data results (bldgs with targets) - W/O targets: Same, but auditor shall review results and ensure package of ECM’s meets 75% of projected savings.
