ENGIE Impact - BPS Process

Page 1


The Building Performance Standards Compliance Advisory process will occur in 4 steps

Analyze

Results & Compliance Pathways

BPS Report & Compliance Roadmap

• Site list review

• Initial data collection

• Data completeness check

• Data alignment and questions

• Apply regulations and requirements to portfolio

• Recommend and verify Compliance Pathways with client

• Safety and onsite procedure discussions

• Preliminary site analysis and prioritization

• Site visit scheduling and execution with facilities team

• Review data collected onsite

• Perform opportunity analysis and calculations

• Analyze compliance status and potential pathways in each applicable jurisdiction

• Prepare onsite audit report

• Prepare BPS Compliance Roadmap

• Submit documentation to jurisdictions

• Present final summary

Compliance with immediate requirements, including an on-site energy audit, submission of audit report, and additional documentation where required

Actionable roadmap to compliance with relevant building performance target

Step 1: Collect & Review Preliminary Data

In this step, ENGIE Impact will collect and request relevant available data about each site, review, and confirm compliance requirements

Process Sample Checklist

• Review site list and confirm scope

• Stakeholder alignment

• Initial data collection according to checklist

• Data completeness check

• Apply regulations and requirements to portfolio to determine actions and documentation needed at each site

Data and Information Requested

✓ Two Years Monthly Utility data

✓ Facility attributes (size, age, remodel dates)

✓ Two years production, utilization, occupancy, traffic, etc

✓ Facility Plan and MEP As-built Drawings

✓ Equipment inventories/Asset Lists

✓ CapEx project lists / plans (identified, in-progress, approved, planned)

✓ Vendor proposals for unimplemented / hold projects

✓ Portfolio growth / contraction forecasts (acquisitions or divestments)

✓ Information on Existing Building Energy Management System

✓ Existing onsite renewable data

✓ Details of recently completed efficiency and or on-site generation projects

✓ List of key stakeholders and contact information

✓ Financial hurdle rates / investment requirements

✓ Growth plans of the business (divestment, acquisitions, new markets)

✓ Purchasing/Efficiency standards

✓ Relevant risk assessment and mitigation strategies

Step 2 – On-site Energy Audit

A qualified ENGIE Impact auditor will facilitate an ASHRAE Level 2 audit at each site as outlined in ASHRAE Standard 211-2018

Process

Detailed energy survey analysis

• Perform a whole building survey

• Examine major energy and water utilization systems and equipment

• Interview on-site staff to understand operating procedures

• Analyze utility bills over a longer timeframe to understand seasonal variations and energy patterns

Energy breakdown

• Breakdown of energy consumption by end-use (lighting, HVAC, etc.) in detail to highlight areas with the most significant savings potential

Identification and financial analysis of measures

• Propose energy conservation measures (ECMs) and cost savings opportunities

• Estimate cost-effectiveness and financial payback period of proposed improvements

Actionable recommendations

• The audit provides the foundation for a clear roadmap for improvement, outlining specific ECMs like upgrading equipment, improving building envelope performance, and optimizing operational practices

Step 2

Areas of focus during an ASHRAE Level 2 audit

• Schedules and setpoints

• Maintenance schedules

HVAC

• Equipment replacement

• BAS (if applicable)

• IndoorAir Quality/COVID changes

• Schedules and controls

Lighting

• Replacement guidelines

• Leveraging daylighting techniques

Building

Envelope

Specialty Equipment

• Entrances and exits

• Windows

• Roofs

• Insulation

General

• Studio equipment

• Plugload controls

• Kitchen equipment

• Start up and shut down

• Hot water

• Irrigation control

Step 3 – Post-Audit Performance Analysis

ENGIE Impact will analyze results from each on-site energy audit

Process

Compile data and observations for each site

• Consolidate notes and request additional information as needed

• Generate an end-use breakdown to understand drivers of energy use

• Review existing conditions of all equipment

• Calculate energy, carbon, and cost savings potential

• Identify energy conservation measures (ECM) and estimate cost and payback

Analyze compliance status and potential compliance pathways

• Examine current state energy performance versus the target for the relevant jurisdiction

• Analyze and recommend a compliance pathway for each site

• Estimate penalties from noncompliance

Output

• Initial audit report

• Compliance pathway recommendation and selection

Step 4 – Develop and Submit Compliance Roadmap

ENGIE Impact will produce necessary documents to submit to the jurisdiction and a summary of all sites visited

Process

Develop site-level audit report and additional documentation as required

• Prepare audit report including described in previous step

• Energy conservation measure calculation and descriptions

• Recommended project prioritization and capital planning based on individual building’s target

• Prepare any additional documentation as required by the jurisdiction

• Submit all required documentation to jurisdiction

Develop final portfolio summary report for sites visited

• Develop report summarizing findings at a portfolio or jurisdiction level, recommended phased project prioritization and capital planning

• Submit to Client only

Output

• Submittal of initial BPS or energy audit requirements as per the jurisdiction, which can include the energy audit, supplemental documentation, compliance roadmap, compliance pathway selection, etc.

• Overview of portfolio performance, recommendations for highest priority focus areas to achieve compliance and maximize investment
