Arc Supports for GRESB
February 2022
GRESB is the global benchmark for the environmental, social, and governance (ESG)
performance of real asset companies and funds. Many partners help GRESB participantsorganize and submit data. Arc works on the other side of the GRESB process; helping portfolio
managers do more with asset data and achieve higher GRESB scores.
Highlights●GRESB participants have multiple options to enter, link, or sync asset data, including
manual data enter, spreadsheet uploads, or connecting to ENERGY STAR,
Measurabl, Bractlet, Energy Watch, Wattics, QLEAR, Schneider Electric, and otherpartners.

●Arc provides opportunities to improve GRESB scores with operational building
certifications, energy ratings, waste management, employee engagement, tenantsatisfaction, risk assessment, and more.

●Arc tools provide a streamlined, data-driven path to LEED v4.1 O+M orRecertification.

Getting Started
Arc provides several pathways for GRESB participants to upload or link GRESB Asset data:

1. Arc can upload a GRESB Asset Spreadsheet. Arc users can find this tool in the Portfolio
section. It is available to all Arc users. Uploading a GRESB Asset Spreadsheet translates theGRESB structure into Arc and provides estimated Arc Performance Scores for energy, water,and waste. These are accompanied by an indication of the number of assumptions madeduring this conversion (e.g., estimates of occupancy, schedule, etc.). Arc users can add
data or edit parameters to generate full Arc Performance Scores and, for Arc Essentials users,
create LEED Readiness assessments as part of project and portfolio reports.

2. Arc users can connect projects via a partner. Arc maintains data connections with agrowing ecosystem of partners that collect and manage asset data for GRESB submission,
including arbnco, ENERGY STAR Portfolio Manager, Energy Watch, Meaurabl, Schneider
Electric, Bracelet, Wattics, QLEAR, Idun, and FGB Studio. Data managed by any of thesepartners can be connected to Arc. More information about how to activate eachconnection is found in the Apps section after signing into Arc.

3. Arc users can upload multiple projects via spreadsheet. Arc has a custom MicrosoftExcel workbook to load multiple projects. This spreadsheet can be used to organize and load
any number of projects. It allows for the bulk entry of any required Arc field, an advantage
over the GRESB spreadsheet. The workbook is available upon request fromcontact@arcskoru.com. The Arc team will advise users on the use of the workbook, and Arc
will load the data. Arc may charge a setup fee to support large or complex portfolios.

Improving GRESB Scores
Linking or loading projects is a starting point to understand sustainability performance and, inturn, earn higher GRESB scores. For 2022, new Arc tools and capabilities have expanded
opportunities to improve GRESB outcomes. These include opportunities that can be realized
over relatively short periods of time (e.g., risk assessments, energy ratings).

1. Building Certification. Arc powers LEED certification for existing spaces and wholebuildings. LEED certifications earn GRESB points for operational building certificates (BC 1.2). It2

is important to note that portfolio managers with existing LEED Building Design & Construction
certifications (BD&C) can improve their scores by using performance-based LEED
Recertification to achieve an operational building certificate. This streamlined process relies
on performance data and past certification.
Pro Tip: Performance-based recertification provides a fast, streamlined way to earn GRESB
points by adding operational building certificates to earlier design/construction building
certificates.

2. Energy Ratings. Arc can generate Performance Certificates. Energy ratings receive
recognition for GRESB indicator BC 2. Performance Certificates provide Arc Performance
Scores and key performance indicators for specified time periods. Performance Certificatesare available by subscription or in discounted bundles for portfolio users.
Pro Tip: Arc energy ratings can be generated on-demand for any space or building. Arc
recommends assets have 12-months of monthly energy data.

3. Human Experience. Surveys are an integral part of the Human Experience performance
category. Arc surveys can earn GRESB points related to employee and tenant engagement,
including SE 2.1, TC1.0, and TC 2.1. These surveys are available to all Arc users. If needed,
survey responses can be exported and submitted as documentation by generating a reportfrom the “gear” at the top of the Meters & Surveys menu.
Pro Tip: Arc Human Experience information should be entered into GRESB Portal as“independent third party” with an “overall satisfaction” metric. Response rates arecalculated and displayed in the Arc dashboard.

4. Waste management. Arc meets GRESB requirements for waste management (RA5).
Assets tracking waste in Arc based on LEED guidelines can earn GRESB points for on-going
waste performance monitoring, recycling, and waste stream audits.
Pro Tip: Waste audits can contribute to both GRESB and LEED. They are a useful tool tounderstand and manage waste streams. More information about the Arc Waste
Performance Score and the support LEED v2009 waste stream audit credit.

35. Risk assessment. Arc Climate Risk tools help GRESB participants earn points for the Risk
Assessment for Standing Investments Portfolio criteria (RA1). This GRESB indicator includes anextensive list of options. Arc supports these in two ways:●All Arc users can calculate energy scores for source energy and GHG emissions -supporting a positive response to the energy efficiency, energy supply, and GHG
emissions criteria●Arc Climate Risk adds support for the flooding and natural hazard criteria

As with other GRESB criteria, these assessments are scored as a percentage of the total
portfolio.
Pro Tip: Arc Climate Risk can quickly increase portfolio coverage for transition and physicalrisk.
