Overview
Local Government CodeSec. 399.002. DEFINITIONS. • Qualified Improvement – Permanent improvement fixed to property
– Customer side of the meter
– Decrease water or energy consumption or demand
– Energy technology to generate electricity, provide thermal energy, or regulate temperature
Overview
Local Government CodeSec. 399.011. REVIEW REQUIRED. • Independent third party• Before construction activities– Review of water or energy baseline conditions
– Review of projected water or energy savings
• After project is completed– Verification that the qualified project was properly
completed and is operating as intended
Overview
ParticipantsProperty Owner– Separate contracts
Independent Third Party Review (ITPR) Engineer– At beginning and through PACE contract
Engineer of Record– At beginning and through construction phase
Contractor– At beginning, construction and M+V
Overview
Technical StandardsInvestor Confidence Project (ICP) Energy Performance Protocols (EPP) for Standard and Large Commercial Facilities
Standardize the technical review of energy efficiency projects to bring uniformity and reliability on a national scale
Overview
Technical RequirementsStep 1: Establish BaselineWater and energy use must be measured
Step 2: Project SavingsWater and energy conserving measures must be quantified
Step 3: Independent Third Party ReviewProject must be reviewed by the ITPR Engineer
Step 4: Annual ReportingProperty Owner reports savings to PACE Administrator

Independent Third Party Review
The ITPR EngineerTechnical Standards Manual – Section II
• Selected by the property owner• Validates projected future energy or water
savings (not an original review) • Verifies that project was properly completed
and is operating as intended• Reviews and validates of post-construction
M&V reports• Ideally, the same ITPR should follow a project
from initial review to project completion
Independent Third Party Review
ITPR Engineer QualificationsTechnical Standards Manual – Section II
• Licensed Professional Engineer with energy/water efficiency experience
• Without conflict or relationship to the project • One of the following certifications:
– American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE)
– Building Energy Assessment Professional (BEAP)– Building Energy Modeling Professional– Association of Energy Engineers (AEE)– Certified Energy Manager (CEM)– Certified Measurement and Verification Professional (CMVP)– Certified Energy Auditor (CEA)– Building Commissioning Association– Certified Commissioning Professional– Investor Confidence Project (ICP) Credentialed Quality Assurance Provider
Independent Third Party Review
ITPR Engineer CertificationsTechnical Standards Manual – Section II
• Reviewer’s Certification• Statement of Compliance
Independent Third Party Review (ITPR)
ITPR Engineer Site VisitsTechnical Standards Manual – Section II
Site Visit 1: Reviewer’s Certification
• Reviews completed Energy/Water Assessment Report
• Visits site
• Project Verification Certificate
– No conflict of interest– Certification that project complies with PACE guidelines– Sealed by Texas Professional Engineer
Independent Third Party Review (ITPR)
ITPR Site Visits (cont.)Technical Standards Manual – Section II
Site Visit 2: Statement of Compliance

• Revisit the site to confirm that the improvements were properly installed, meet EPP guidelines, and are operating as intended
• Statement of Compliance– No conflict of interest– Certification that project complies with PACE guidelines– Sealed by Texas Professional Engineer
Project Process
• Engage Independent Third Party Reviewer (ITPR)
• Engage Engineer of Record– Full Assessment– FAST TRACK Assessment

Full Assessment / Fast Track ProtocolEngineer of Record ResponsibilitiesTechnical Standards Manual – Section III
• Multiple Energy and/or Water Efficiency Measure Projects
Fast Track• Type 1 – Like-for-Like
Replacement – Example: Lighting retrofit or A/C
unit upgrade
• Type 2 – Single-Measure Efficiency Projects – Example: Window film,
additional insulation, or reflective roof coating
• Type 3 - Distributed Generation – Examples: CHP, micro turbines,
solar photovoltaic (PV)
Full Assessment
Full Assessment / Fast Track ProtocolEngineer of Record ResponsibilitiesTechnical Standards Manual – Section III
Fast Track• Projects do not qualify for
the FAST TRACK approach if:– Project requires energy
modeling – Project requires IPMVP
(Option C or D) measurement and verification
– Project value to building appraisal ratio exceeds 0.10 (10%)
Full Assessment
ProtocolEngineer of Record ResponsibilitiesTechnical Standards Manual – Section III
1. Establishes energy and water baseline conditions 2. Prepares the Energy/Water Assessment Report3. Provides oversight during construction activities4. Evaluates project performance (M&V)
ProtocolApproaches for Different Project TypesTechnical Standards Manual – Section III1. Commercial Projects– ASHRAE standards based
2. Industrial and Agricultural Projects– Facility, process or equipment
3. Distributed Generation (DG)– Metering of delivered energy without a baseline
is often recommended in the M&V approach– Delivers energy on customer side of meter
Protocol
Using Prior AuditsTechnical Standards Manual – Section III
Engineer of Record:• Prior ASHRAE Level II or Level III energy/water
audit may be used provided that it was completed within the last three (3) years – see conditions
• Update baseline utility data
Protocol
Projected Savings CalculationsTechnical Standards Manual – Section III
Engineer of Record
• “Open book” methodology – Savings calculations are transparent – Results are readily verifiable
• “Closed book” methodology (proprietary software is prohibited) – Exception – If it meets open book methodology
standards
Project Process
• Engage Independent Third Party Reviewer (ITPR)
• Engage Engineer of Record– Full Assessment– FAST TRACK Assessment
• Engage Contractor if Design Build Contract
• Measurement and Verification (M&V)– Plan (decide at beginning)– Implementation

Texas PACE law: “After a qualified project is completed, the local government shall obtain verification that the qualified project was properly completed and is operating as intended.”
• ITPR Engineer Validation– ASHRAE Guideline 14, Whole Building Performance Path and
the International Performance Measurement and Verification Protocol (IPMVP)
– IPMVP Options (Decided when Full Assessment is Developed)
• Owner’s Contractor– May continue M&V throughout the term of the assessment or
