Glossary of Terms for PowerScore

Resource Innovation Institute is an objective, data-driven non-profit organization whose mission is to measure, verify and celebrate the world's most efficient agricultural ideas.

GENERAL

PowerScore
RII’s specialized resource benchmarking platform for controlled environment agriculture production facilities. PowerScore generates KPIs for resource efficiency and productivity of energy, water, emissions, and waste. The PowerScore platform includes several components: intake websites and surveys, facility Performance Snapshots, crop-specific Ranked Data Sets, user profiles, dashboards, and comparative analysis reports. PowerScore’s free service enables producers to enter self-reported data through the online PowerScore platform to get an unverified Performance Snapshot sharing key performance indicators and measuring year-over-year changes in your facility performance. For CEA markets where there is a statistically significant crop-specific Ranked Data Set, Performance Snapshots provide an unverified informative Facility Ranking.

PowerScore Pro
Enhanced PowerScore dashboard and comparative analysis and reporting platform that enables benchmarking across portfolios of facilities designed for producers with multiple facilities (like MSOs), global investors, efficiency programs, and design & construction partners. RII members can access PowerScore Pro and receive Competitive Facility Rankings.

PowerScore Comply
PowerScore intake survey available in markets where resource performance reporting is required and PowerScore is specified as a qualified benchmarking platform. Cannabis cultivation license-holders can report required facility performance details, such as annual production and monthly resource consumption.

PowerScore Flow
PowerScore intake survey for users to benchmark facilities using water consumption for water efficiency and productivity KPIs. This is currently an unpromoted feature.

DATA

Facility
The site (land and buildings) that comprises a controlled environment agriculture operation whose resource consumption and production efficiency is benchmarked in a PowerScore Performance Snapshot. PowerScore facilities are described in terms of average canopy area under production.

Performance Snapshot
Facility benchmarking summary of one year of production and resource consumption data that can also provide a Year-Over-Year Ranking and/or Facility Rankings. Performance Snapshots display key performance indicators, rankings, filters, and facility details from survey responses. Each Snapshot is unique and is described as a ‘PowerScore record’, and accessed with a unique URL.

Ranked Data Set
Complete data set of PowerScore records with archived records removed. Newly submitted records are reviewed for approval before being added by RII staff into the Ranked Data Set. Records flagged for data quality issues may be automatically or manually removed.

Verified PowerScore
Enhanced benchmarking service available to PowerScore Pro subscribers. System-reported data submitted for KPIs and rankings are validated by RII and marked as Verified on the facility’s Performance Snapshot on each KPI that has been third-party verified with utility bills and system monitoring reports.

Facility Types:

Indoor
Facilities are classified as Indoor if plants are grown under only electric light in their most advanced growth stage reported for the facility (most commonly, this is the flowering stage).

Greenhouse / Mixed Light: Ventilated and Hybrid
Facilities are classified as Mixed light if plants are grown for at least one harvest under both sunlight and electric light in their most advanced growth stage (most commonly, this is the flowering stage) in a greenhouse, hoop-house, glasshouse, conservatory, hothouse, or other similar structure.

Ventilated greenhouses use traditional greenhouse construction and have permeable building envelopes.

Sealed, or Hybrid greenhouse facilities are high-performance greenhouse operations in buildings with well-sealed and insulated building envelopes.

Outdoor
Facilities are classified as Outdoor if plants are grown under only sunlight in their most advanced growth stage reported for the facility (most commonly, this is the flowering stage) in rows or hoop houses.

Reporting


Year-Over-Year Ranking

If enough data is provided, a Performance Snapshot will include a comparison of prior years’ key performance indicators and summarize the difference with a Year-Over-Year Ranking. At least two full years of data are required to calculate year-over-year changes in KPIs. When comparing one submission (PowerScore A) to another submission (PowerScore B), each KPI is calculated like this:

= ( PowerScore A's KPI - PowerScore B's KPI )
/ PowerScore B's KPI


Facility Ranking
When enough data is provided in a crop-specific Ranked Data Set, unverified informative Facility Rankings describe a facility’s overall percentile ranking for a given 12 months of data. Facility Rankings use three key performance indicator (KPI) categories: 1) Energy Efficiency & Productivity, 2) Water Efficiency & Productivity, and 3) Waste Efficiency & Productivity. The Facility Ranking weighs the KPI categories: (Energy*50%)+(Water*25%)+(Waste*25%). Each Facility Ranking is then compared to operations of the same cultivation type in the appropriate crop-specific Ranked Data Set. This provides a full range of 0th to 100th percentile rankings, displayed with the PowerScore gauge.

Note: If a record does not have scores for all three categories, the category ratios are adjusted. For example, different scores may be calculated with (Energy*100%), or with Energy*67%)+(Water*33%), or with (Water*50%)+(Waste*50%).

Competitive Facility Ranking
Competitive Facility Rankings are enhanced Facility Rankings compared against specific years of Ranked Data Set records to assess KPI trends (year over year changes against the most recent Ranked Data Set).

Producer Resource Efficiency Plan (PREP)
Facility benchmarking summary that gathers PowerScore Performance Snapshot KPI trends, internal operational insights, and competitive recommendations for operators to consider to improve KPI performance and Facility Ranking.

Key Performance Indicator Rankings
KPI rankings are displayed on Performance Benchmark Reports using graduated bar scales displaying percentiles ranked relative to records in the Ranked Data Set that cultivate in the same way (indoor is compared against indoor, etc).
