LEED CHARRETTE
WHAT IS A LEED CHARRETTE?
A charrette is an intensive, one or two-day collaborative session where building stakeholders and building experts address particular design or project issues.
The goal is to generate possible design solutions and strategies to kick-off LEED implementation.

SS 1D – Heat Island Effect, Non-Roof
The LEED Submittal Template has been provided stating that the building site has 87.35% underground or covered parking. A minimum of 50% is required. The calculation, aerial photo, letter describing the parking, and a narrative provided support these claims.
One half point is anticipated.
Please note that two half points must be achieved to earn one full point.

Action
Move Green Cleaning from ID to SS1 for ½ credit for full credit
6
ID 1.2 – Innovation in Design Green Cleaning
The green cleaning strategy applies to the entire campus. Therefore, the strategy is applicable to SSc1 instead of IDc1.
Provide a narrative demonstrating that the Green Cleaning Program not applicable to the entire building or campus. Alternatively, the Project Team may pursue credit through SSc1.

Action
Pursue credit
through SS1L

SS 1L – Green Cleaning
This strategy is applied to the entire building, and it is an acceptable strategy for an SSc1 half point. However, documentation identifying the date and activities associated with floor maintenance has not been provided as required. One half point denied.
NOTE:For future project please provide the LEED Submittal Template of the applied rating system and credit.

Action
Appeal for $500. Include letter regarding date and activities associated with floor maintenance.

6 PROJECT SUMMARYDesign Review Result - AWARDED
Best Practices for LEED SS 1L Green Cleaning
1. Green cleaning is an ID credit when the project is proposing a new green cleaning strategy for the entire campus. Adopting an existing green cleaning strategy does not warrant an ID credit.
2. If the credit is not an innovation and addressed in another resource guide, it can be documented in SS1L for ½ credit.
3. Credit under SS1L should be documented with the submittal information requested from the pertinent rating system and not the ID credit.
6
SS 3.2 – Bicycle Storage & Changing Rooms
The bike racks identified in the provided documentation appear to be for the entire campus. However, the calculations are based on project occupancy.
The calculations indicate occupancy for the project (22) that is inconsistent with WEc1.1(25). All occupancy numbers must be reported consistently across all LEED credit submittals.
The provided letter states that employees are required to pay a monthly fee to have access to showers. The LEED-CI Reference Guide states that access to a health and fitness club, provided within the lease agreement, on the property in which the project is located meets the credit intent a long as there is unlimited free access to the showering facilities for the tenants.

Best Practices for LEED SS3.2 Bicycle Storage & Changing Rooms
1. Existing bicycle storage must be specific to project to earn this credit. Bicycle storage cannot be shared.
2. Verify occupancy is consistent through all credits
3. Shower and changing rooms must be free of charge
6
WE1.1 – Water Use Reduction
All occupancy numbers must be reported consistently across all LEED credit submittals.
Unless special conditions exist, projects should assume a 50 / 50 male / female ratio and an average of three fixture uses per day. Include visitors and transient occupants.
The water use calculations do not include all of the required EPAct fixtures (faucets, water closets, showers, and urinals). The project must document the EPAct fixtures used by the occupants even if they are not included in the project scope of work.
The water use calculations include process water consuming fixtures which are not included in the EPAct.

Best Practices for LEED WE 1.1 – Water use Reduction
1. Include all existing fixtures used by occupants in the calculation
2. Do not include process water fixtures in the calculation.
3. An innovation credit may be attempted by using water efficient process water fixtures. However, this may need to be applied to the entire building. See CIR.

EA 1.1 – Optimize Energy Performance – Lighting Power
The LEED Submittal Template has been provided stating a 16.72% reduction in connected lighting power density, using the space-by-space method, over that allowed by ASHRAE/IESNA Standard 90.1-2004. The ASHRAE/IESNA Standard 90.1-2004 User's Manual, Lighting Compliance Documentation and calculations have been provided. However, it is unclear if task lighting has been included.
Please provide a narrative with a brief description of task lighting. Provide a Revised LEED Submittal Template and Lighting Compliance Documentation as appropriate.

EQ 1 – Outside Air Delivery MonitoringIt is not clear if outdoor airflow measurement devices are capable of measuring the minimum outdoor airflow rate at all expected system operating conditions within 15% of the design minimum outdoor air rate.
It does not appear that the outdoor airflow monitors are configured to generate an alarm if the indicated outdoor airflow rate drops more than 10% below the minimum outdoor air rate required by Standard 62.1 2004.
The requirements for densely occupied spaces do not appear to have been addressed.

EQ 6.1 – Controllability of Systems, Lighting
The number of occupants enabled to make adjustments to suit individual task needs and preferences is unclear. Additionally, it is not clear if occupants in multi-occupant spaces have the ability to adjust lighting to suit their activities.
Provide a narrative describing the lighting controls enabling occupants to make adjustments to suit individual task needs and preferences. Provide calculations demonstrating that at least 90% of occupants have these controls. In addition, for all shared multi-occupant spaces, describe the activities and types of lighting controls available to the occupants demonstrating that lighting controls provide activity functionality.

EQ 6.2 – Controllability of Systems, Temperature and Ventilation
The documentation does not demonstrate that at least 50% of the space occupants have the ability to make adjustments to suit individual needs and preferences. To satisfy this portion of the requirement, all open plan workstations, private offices, and reception stations must be included in the count. Confirm that 50% or more of individuals occupying these locations have at least one means of individual control over thermal comfort.
Provide documentation, such as narrative and plans to demonstrate that at least 50% of occupants are provided with temperature and ventilation adjustments.
6 PROJECT SUMMARYDesign Review Comments and Resubmittal

6
EQ 6.2 – Controllability of Systems, Temperature and Ventilation
A narrative has been provided stating that all rooms have their own thermostat and that the open lab has two thermostats. This credit requires that 50% of the occupants must have the ability to make adjustments to suit individual needs and preferences.
The narrative provided with IEQc6.1 states that there are 20 occupants in the open lab. Thus, at least 18 of the 25 project occupants do not have the ability to make adjustments to suit individual needs and preferences. The documentation does not demonstrate credit compliance.
