iIntroduction
Insight was developed by Skanska USA, the U.S. Green Building Council (USGBC), andArc Skoru Inc. (Arc). Insight uses the Leadership in Energy and Environmental Design(LEED) project database to provide information about energy, water and waste design
goals across regions and within targeted project types.
Insight interprets and aggregates project-level information and makes it easily
accessible to those making decisions about the design and performance of buildings.
Insight is currently limited to LEED New Construction projects.
Early adopters of Insight have applied the tools for business development, projectvisioning, and conceptual design.

Insight Solutions••Analyze project design goals for energy, water, and waste;
Evaluate the achievement rate for LEED strategies;• View progress toward net zero energy with zEPI scores; •Create and compare alternative project designs;• Export high-quality reports and supporting data.

Access Insight
Insight is available to Arc Essentials users through ArcSkoru.com. There are three steps toget started.
1. Use your USGBC Username and Password to access ArcSkoru.com. You cancreate a new account for free on USGBC.org.
2. Upgrade your account to Arc Essentials
3. Select Insight from the top navigation
Enter a search for a location or create a model and explore!

1Analyze
Insight provides tools to analyze green building activity in markets around the world.
Start with the Markets tile. Enter an address or place name – anywhere recognized byGoogle will work.
Then, select a search radius and, optionally, select one or more project types. Not
selecting a project type will return all LEED projects within the radius. Click Search tocontinue.
The Insight tool pulls information for all LEED New Construction projects contained in theUSGBC’s database that are publicly accessible (not marked as private/confidential),from version 2.1 and onwards.

ProjectsThe search defaults to a Project View with a map and project list. The searchparameters are displayed below the total number of projects. Zooming in and clickingon the red symbols on the map displays the project names and USGBC project
numbers. Note, only non-confidential projects are LEED projects are displayed on themap. In some cases, errors or incomplete address information may result in missing or
misplaced projects. Project information can be updated in LEED Online or bycontacting GBCI Customer Service.
2Metrics
EnergyInsight uses the zEPI scale to compare the designed energy performance of buildings
across LEED versions, helping push the conversation and market towards net zero. A
score of 100 equates to the average energy performance of U.S. building stock in theyear 2000. A net zero energy building would have a score of 0. The designed energy
performance for buildings in your data set is displayed on the zEPI scale. Projects aregrouped into deciles to improve display quality.
Both the ASHRAE 90.1 2010 Energy code baseline and the LEED v4 prerequisite (5%better than AHSRAE 90.1 2010) are shown as vertical lines to serve as reference points.
Calculations are based on the Optimize Energy Performance credits and prerequisites
in LEED, building type, location, and climate zones.
The LEED credits used to calculate the energy metric include Energy & Atmosphere (EA)
credit 1.1-EAc1.10 in LEED version 2.1 and version 2.2, EA prerequisite 1, EA prerequisite
2, EAc1.1-EAc1.19 in LEED 2009 and the Optimize Energy Performance prerequisite andcredits in LEED version 4. The database aggregates LEED certified new construction andmajor renovation projects. The zEPI score is based on the energy performance of newconstruction projects. Be aware that the energy reduction view will depict higher
energy performance than average for renovation projects.

projects within 10 miles of 2101 L Street, NW, Washington, D.C. Lower scores indicate
more ambitious, higher performance designs.

Water
Water savings are calculated with reference to EPAct 1992. For U.S. projects, this can beinterpreted as improvement relative to regulatory minimum performance standards. Of
course, local requirements may exceed these levels, and these are not captured in thetool. Similarly, some jurisdictions may have lower or no regulatory requirements. The
savings calculation will underestimate benefits for these locations.
Projects that did not achieve the LEED credit show up as a 0% water savings (relative toEPAct 1992) and are not used to calculate the percent average reduction. LEEDcredits WEc3.1, WEc3.2 in v2.1, v 2.2, v3, WEp1 in v3 and the Indoor water use credits
and prerequisite in v4 form the basis of this data.

WasteWaste reduction metrics reflect construction and demolition (C&D) waste diverted fromlandfill. LEED credits MRc2.1, 2.2 in V 2.1, 2.2 and 3 and the Construction and Demolition
Waste Management credit in LEED v4 form the basis of this data. There is no widely usednational or international benchmark for C&D waste, and it is reasonable to expect thatpractices will vary significantly between markets and regions.
Projects that did not achieve these credits are shown as having a 0% diversion fromlandfill and are not used to calculate the average diversion.

Strategies
The Strategies tab provides details about the use of green building practices in a given
location and, if selected, property type. Strategies represent an aggregation of similar
LEED credits from multiple building design and construction rating systems. This provides
a synthetic view of practices; however, it does not represent any particular LEEDversion.

6Export
Insight allows users to create a downloadable PDF containing project counts bycertification level, zEPI scores, LEED strategies, and metrics. Users can generate thereport by clicking the Export button at the top of the screen.

7Models
Insight allows users to create “models”. These are tools that can be used to explore how
combinations of credit achievement translate into energy, water, and waste
performance, Models can be compared to each other or regional practices.

What is a Model (in Insight)?
mod·el, noun, a representation of a person or thing or of a proposed structure.
An Insight model is a hypothetical project. Insight models do not represent realprojects or real-world energy use, water consumption, or waste generation. They are
not connected to Arc project data. Information entered into Insight models is notaccessible in other parts of the Arc platform.

Create a ModelGet started by clicking the Create Your First Model button.

Fields include:••[Required] Name: Enter a descriptive name for your project[Required] Version: Use this section to indicate what phase the project is at (e.g.
Order of Magnitude or Design Development) per the standard preconstruction
definitions (found here). This field is automatically populated with Version 1.0, but
we encourage you to update that to something more meaningful that will allow
us to accurately compare between versions as the project progresses.

•[Required] CM/Arch: Enter the Construction Manager (CM). This field can beused to aggregate projects for reporting by CM.

•••[Optional] CM Project Number: Enter your internal project number.
[Optional] Rating System: Enter a rating system to determine energy baseline.
[Optional] Space Type: Enter the project type. This is used in the zEPI calculation.
If the exact type is not available, select the space type that most closely
resembles the energy use profile of the project.

Select LEED Strategies
After entering basic “Model Details”, click the Next button to create your project in thesystem. The next tab displays “Strategies”. The table presents high-level, aggregatedstrategies mirroring, to the degree possible, credit intents. They do not reflect Alternative
Compliance Paths.

10After selecting credits and point achievement, click Next for the reduction view. Thisview presents the estimated energy, water, and waste impact of the selected credits.

Optionally, projects may specify a goal that goes beyond credit achievements levels,
such as zero net energy, water or waste.

11Benchmark Strategies
Clicking Next allows you to benchmark the reductions against existing LEED projects.
The comparison set can be refined by location and project type.

More metrics are available in the How Scoring Works tab. Notably, this displays the zEPI
score and its score components: space type, climate zone, baseline energy code(based on the rating system version), baseline energy use intensity (EUI), energy use
reduction (based on LEED credit achievement), estimated building EUI (baseline – theenergy use reduction).
Project locations are used to look up ASHRAE Climate Zones. Data are based on
ASHRAE Standard 169-2013 for locations across the United States and internationally.
Projects are assigned the climate zone for the closest ASHRAE station. Thesecomponents are used to estimate the zEPI score.

The model created through these steps is automatically saved, and can be retrieved
through the Models tab. The Export Model button creates an Excel file summarizing allmodel parameters and scores.

Compare ProjectsUsers can compare up to three projects in a single view. The user selects a model foreach column. They have the option to create one or more versions of this model.
Reductions are summarized by performance area (energy, water, and waste) or LEED
credit category (e.g., Location & Transportation, Energy & Atmosphere).

efficient performance of buildings. About ASHRAE.
Climate Zones: Climate zones are used as part of the zEPI calculation and are used todescribe the climate in a given region. The US is sorted into eight distinct climate zones,
which are further categorized by sub-climate (moist, dry and marine).

EUI: Refers to the energy use intensity of a building, it is calculated by dividing theenergy used by the square footage. A three-minute video is available on the EnergyStar website to help provide you with a better understanding. For more information:
https://portfoliomanager.zendesk.com/hc/en-us/articles/213381958-What-is-EUIzEPI Score: Historically we have measured energy performance as a percent better
than code, but that kind of baseline continually shifts as new, more stringent codes areadopted. zEPI eliminates the challenge of comparing buildings across time and codes
by setting an absolute scale where the end points are the average performance of US
building stock in the year 2000 (a score of 100) and zero net energy (a score of 0). The
zEPI scale extends in a linear fashion between, above, and below those two points. Forexample, a building that uses twice as much energy as an average building receives ascore of a 200. A building that uses half as much energy as an average buildingreceives a score of 50. It is normalized for building type and climate.
