Delete "in the system" from the first sentence of the second paragraph.
Revise the last sentence in the 4th paragraph to read as: Initial certification projects that include at least three additional contaminants can use this as an Innovation Strategy under the Innovation credit.
Under Step by Step, Step 1, revise first paragraph to read as: "Administer an occupant comfort survey for the building. Conduct the survey in the Arc/LEED Online platform or via an alternative method. If conducting the survey outside of the Arc/LEED Online platform, submit an inquiry to https://www.gbci.org/contact prior to conducting the survey for pre-approval.
Add the following to Step 3, and rename the current Step 3 as Step 4.
"Determine occupant satisfaction score
An occupant satisfaction score will generate for your project once survey response data is entered into Arc/LEED Online and a minimum survey response rate is achieved.
If conducting the survey outside of the Arc/LEED Online platform, contact us at https://www.gbci.org/contact for data upload instructions.
Under the new Step 4, revise second sentence to read as: "Measurements may come from continuous monitoring (via installed sensors) or from one-time air testing"
Revise second paragraph under Step 4 to read as: "Measure in locations that are representative of the different space types in the building."
Add a new paragraph that reads: "For example, the LEEDv4 BD+C Indoor Air Assessment credit states the following as it relates to testing locations: At a minimum, indoor air testing/monitoring locations must cover a) "unventilated or less ventilated occupied spaces b) different space types within the building (e.g. small offices, classroom etc.) or different subtypes in a larger space (e.g. meeting/conference rooms, open office areas, kitchen etc. in a larger office setting) c) any recently renovated/furnished spaces.”
Add the following language to the end of the paragraph that starts "for TVOC...":
"When measuring concentrations below the limit of detection, reported values must be substituted with a value at or above the limit of detection For example, if the detection limit is 150 µg/m3, readings below that value should be provided as 150 µg/m3 and not 0 µg/m3."
Change the former Step 4 to:
"Step 5. Input data for Carbon Dioxide and TVOC
If using one-time air testing, input your project’s CO2 and TVOC measurements, using the Arc Data Template. TVOC data must be reported in µg/m3. CO2 data must be reported in ppm.
The Arc Data Template will calculate the project’s average 95th percentile CO2 value and maximum TVOC value.
If using continuous monitoring, we recommend you sync data directly to the Arc platform via data integration. Contact us at https://www.gbci.org/contact for further information and verification of sensor approach prior to transmitting data to Arc. GBCI verification will include reviewing any conversion factors used for the sensor, sensor detection limits, and processes to scrub raw data before transmitting to Arc.
Revise Required Documentation section to read as:
"- For projects pursuing points through the occupant satisfaction survey
o Completed occupant satisfaction survey including survey dates, occupant type, and satisfaction response.
o If the survey is completed outside of Arc/LEED Online include a copy of the pre-approval from GBCI and a description of the survey methodology and how it meets the survey requirements.
_ For projects pursuing points through the TVOC measurements and/or CO2 measurements:
o Indoor air quality evaluation report, including narrative explaining how test locations were determined, and which measurement methods were used.
o For One-time air testing: Arc data template including dates and times measurements were taken, and the measurement results from each location. If TVOC measurements were taken in other units (such as ppm), also include measurements in original units and any calculation details to demonstrate how the final values were converted to units of µg/m3.
o For continuous monitoring: include any relevant notes from data integration process and communication with GBCI verifying the sensor approach.
-Human experience score results, including occupant satisfaction score result and/or calculated CO2 score result and/or calculated TVOC score. A minimum Performance Score of 40/100 is required for initial certification.
