4 Introduction This Performance Verification Guidebook contains details regarding the Performance Verification phase of WELL Certification for projects pursuing the WELL Community Standard pilot. For more information on WELL Certification and the steps involved in scheduling WELL performance testing, refer to the WELL Certification Guidebook: WELL Community Standard. Performance Verification Performance Verification for the WELL Community Standard entails a data collection phase followed by a Performance Review by a Green Business Certification Inc. (GBCI) WELL Reviewer. Submission of these data is a requirement for WELL Certification and the results of the data collected for each applicable feature are reviewed by GBCI to determine whether or not a feature has been achieved. Purpose of this Guidebook This guidebook dictates the data collection protocol for parameters covered in the following features in the WELL Community Standard: Air o AQU Fundamental Air Quality o LTA Long-Term Air Quality o LTE Enhanced Long-Term Air Quality o STA Short-Term Air Quality o STE Enhanced Short-Term Air Quality Water o WQT Drinking Water Quality o WAD Public Water Additives o PWT Periodic Water Testing o WQO High Quality Drinking Water o WFS Water Feature Sanitation Data Collection The project team is responsible for gathering environmental data (as applicable) during on-site conditions in accordance with this guidebook. Data collected on-site must be analyzed and the results must be reviewed by GBCI before feature compliance can be determined. For the purposes of certification, submission of performance data can only occur after the project has successfully passed Documentation Review. Details of when collection of data can occur are described within the descriptions of the test methods below. 4

5 Data Collection Protocols for the WELL Community Standard Air Within the five performance-based features in the WELL Air Concept, the following pollutants must be monitored: particulate matter (both PM 10 and PM 2.5), ozone (O 3), sulfur dioxide (SO 2), nitrogen dioxide (NO 2) and carbon monoxide (CO). Some pollutants and some measurement intervals (e.g., annual average nitrogen dioxide levels) are only relevant for a particular optimization. If the project is not pursuing the relevant feature, it is not required to collect and submit this information. These guidelines present two data acquisition methods for ambient air quality measurements: monitors installed by the project team (method 1) and publicly available data already collected from existing air quality monitoring stations (method 2). For each pollutant and each measurement interval (e.g., maximum 8-hr average of ozone), project teams may use either of the two methods, and may take an approach that combines methods, using method 1 in some cases and method 2 in others. Method 1: Project-Based Monitoring This method requires projects to conduct an investigation of the outdoor air quality of the site and its immediate surroundings by installing monitoring devices to measure environmental data. Sensitivity The monitoring devices used must meet the requirements described in Table 1. Table 1: Instrument specification and sensitivity Particular Matter Ozone Sulfur dioxide Nitrogen dioxide Carbon monoxide Instrument type light scattering airborne particle counter direct reading instrument direct reading instrument direct reading instrument direct reading instrument Measurement range 1-1,000 μg/m ppb ppb ppb 0-25 ppm Instrument resolution < 15% at 0.5 μm 1 ppb 0.5 ppb 0.5 ppb 0.1 ppm On-screen resolution 1 μg/m 3 1 ppb 1 ppb 1 ppb 1 ppm Lower detectable limit 1 μg/m 3 3 ppb 3 ppb 3 ppb 0.1 ppm 5

6 Location and Proximity Sampling should be representative of the local outdoor air quality of the site and its immediate surroundings and meet the following criteria: Sampling occurs within the project boundary. Not located in unusually dusty or dirty areas. Separated from the edge of the nearest traffic lane by at least 10 m [33 ft]. Positioned 1-2 m [ ft] above ground level. Positioned at least 5 m [16 ft] away from any buildings, walls, or drip line of trees. If no such location exists, a probe may be located closer to a structure so long as it is on the windward side of the building (i.e., not in the lee of the structure, based on prevailing winds). O 3 and NO 2 (if measured) must be sampled from the same location. To the extent possible, the monitoring device should be powered continuously. This may be accomplished via battery-dependent devices, but batteries must be replaced or re-charged promptly, as necessary. Monitoring devices must also be enclosed in an appropriate shelter at all times to protect instruments from moisture and direct sunlight. Monitoring devices must be secured to prevent tampering or loss. Timing For Feature AQU, data must be continuously collected for no less than seven consecutive days at four times each year, with the first day of measurement two to four months apart. For projects to be eligible for optimizations related to air quality (features LTA, LTE, STA, STE), data must be collected for no less than 90 days total, with at least 20 consecutive days per season. All data submitted for Performance Review must have been collected within the previous 12 months. Frequency Devices must report data at intervals no longer than the following: Particulate matter: at least one measurement per 24 hours. Ozone: at least one measurement per 8 hours. Carbon monoxide: at least one measurement per 8 hours. Nitrogen dioxide: at least one measurement per hour for feature STA and at least one measurement per 24 hours for features LTA and LTE. Sulfur dioxide: at least one measurement per hour. Calibration and Maintenance Instrument calibration is vital for accurate data. Project teams must ensure that the instrument is operating within its calibration period during data collection. Documentation attesting to instrument calibration must be submitted through WELL Online. Instrument performance should be maintained over the measurement period. Instrument maintenance processes include regularly cleaning the internal surfaces (especially optics) to prevent the buildup of debris or dust, replacing filters and/or batteries. The project team should 6

7 also regularly examine site conditions near monitoring devices to ensure that no significant changes to the landscape have occurred. Reporting & Compliance Project must submit the complete data set for all environmental parameters measured, including dates and times of monitoring, the instrument type and placement details (including photographs), plus general information about the site. Compliance is based on values collected during the measurement period compared against the requirements in WELL plus a tolerance of 20% for particulate matter, and 5% for ozone, carbon monoxide, nitrogen dioxide and sulfur dioxide. Method 2: Data Station Monitoring Projects may utilize data from an existing data station located within 4 km [2.5 mi] of the project boundary. The regional outdoor air quality information can be obtained from any data station or reported measurements in compliance with device sensitivity requirements listed in Method 1: Project-Based Monitoring or from data sources such as: The World Health Organization at for particulate matter data for the entire world. The U.S. EPA website at for the United States. European Environment Agency at for Europe. New South Wales Office of Environment and Heritage at for Australia. Projects must provide the exact source of information, providing any relevant links or documentation, as appropriate. Timing Data must be available over the course of one year, with at least 75% of time periods accounted for with valid measurements, and with no less than 50 days of data per season. Analysis may not discard any data that are available within the one-year period (i.e., data filtering is not permitted). Projects must use the most recent data available. Reported data must not be older than 5 years. Frequency See Frequency in Method 1: Project-Based Monitoring. Reporting & Compliance Projects must submit all information published by the data source on relevant features and measured environmental parameters. For example, Feature AQU includes thresholds for the fourth highest 24-hour average (the 99 th percentile) of PM 2.5. If the data source publishes data labeled as the 99 th percentile, the project would submit that value; if the source published the 24-hour average PM 2.5 for all days in the year, the project would submit all the values in addition to the calculated 99 th percentile. 7

8 Projects may extrapolate data that are available to a more stringent reporting value. For example, if a project has data available showing the highest daily PM 10 level is less than 150 µg/m³, it may infer that the fourth highest is also less than 150 µg/m³ and the requirement for Part 1.d of Feature AQU is met. However, the project would not be able use 95 th percentile data in lieu of 99 th percentile, since the 99 th percentile value will always be higher than the 95 th percentile. Compliance is based on values collected during the measurement period compared against the requirements in WELL plus a tolerance of 20% for particulate matter, and 5% for ozone, carbon monoxide, nitrogen dioxide and sulfur dioxide. Water Features WQT, WAD, PWT and WQO require testing contaminant levels in outdoor drinking water fountains located in public use areas. Note that the contaminant concentrations obtained for PWT are not used for certification purposes. Refer to the instructions in the Water section of the WELL Performance Verification Guidebook for buildings for instructions on how to collect and report this information. Projects must test at 5% of relevant water fountains (rounding up), with a maximum of three fountains. Feature WFS requires tests in water used for various recreational purposes. Part 1 requires tests for coliforms in several bodies of water, performed every two weeks. Refer to the WELL Performance Verification Guidebook for buildings for instructions. Part 2 requires testing of different chemicals associated with water disinfection. Tests must be done using kits or devices that comply with NSF/ANSI Standard relating to Equipment for Swimming Pools, Spas, Hot Tubs, and Other Recreational Water Facilities or any more recent version. Tests for chlorine or bromine levels and ph are done on a daily basis while the interactive water feature is in operation. Projects are only required to test for the disinfectant(s) they use. Tests for cyanuric acid are done every seven days (while the water feature is in operation) and are only necessary if chlorine is used as a disinfectant. 8
