MEMORANDUM:
Please review the narrative below in conjunction with the Preliminary LEED checklist
(attached)
Location and Transportation
Floodplain avoidance - Prerequisite
The proposed development is not within a flood plain
Site Selection:
The proposed development utilizes a previously developed lot (4 points) and is
considered infill development (2 points) and is located within an existing street network
(1 point)
Compact Development:
The proposed development provides more than 55 Dwelling units/ acre (2 points)
Community Resources:
The proposed development is within 1/2 mile walking distance to more than 12
community uses such as supermarkets, community-serving retail, community services
such as banks, civic and community facilities. 2 points are anticipated.
Access to Transit:
The proposed development is within 1/4 mile walking distance of a bus stop (Routes
929 and 704). The number of points is dependent on the minimum daily transit service
based on the number of trips. 2 points are anticipated. At least 1 point will be obtained.
Sustainable Sites
Construction activity pollution prevention - Prerequisite
The proposed development will comply with local, state and federal regulations with
regards to controlling soil erosion, waterway sedimentation and airborne dust during
construction.
No invasive plants - Prerequisite
The proposed development will not use any invasive plant species
Attachment 12
Heat Island Reduction:
The proposed development will have more than 75% of hardscape and roof surfaces
either shaded or shall be of a light - colored, high - albedo material or vegetation covered
(2 points)
Rainwater management:
The proposed development will utilize low- impact development (LID) techniques to
minimize the amount of stormwater that leaves the site. By utilizing planters on roofs
and at grade, infiltration planters and permeable paving, we anticipate 65 -79% of the
total lot area will comply (2 points)
Non -toxic pest control:
It is not anticipated that the project will attempt these 2 points at this time.
Water Efficiency
Water metering - Prerequisite
The proposed development will install a water submeter for each unit and residents will
be aware of their individual water use.
Total water use:
The proposed development will utilize high efficiency plumbing fixtures and water
efficient landscaping irrigation and drought tolerant plants. Of the 12 available points
for this credit we anticipate obtaining 5 points by reducing overall indoor and outdoor
water use by 30% over baseline.
Energy and Atmosphere
Minimum energy performance - Prerequisite
The proposed development will be 5% betterthan the baseline energy performance rating
based on ASHRAE Standard 90.1 -2010, as shown via a whole - building energy simulation. The
development will be commissioned using Energy Star protocols or a prescriptive path.
Energy metering - Prerequisite
The proposed development will have an electric submeter for each unit and residents
will be aware of their individual energy use.
Education of homeowner ortenant - Prerequisite
The developer shall create an operations and maintenance manual and provide to all tenants
outlining the energy efficient features of their home.
Annual energy use:
Of the 30 available points for this credit we anticipate obtaining 15 points by improving
the building's energy performance by 20% over baseline (ASH RAE 90.1 -2010)
Efficient hot water distribution system:
The proposed development shall be designed with an energy efficient hot water
distribution system based on maximum pipe length requirements or maximum pipe
volume limits (2 points). In addition insulation will be provided on all domestic hot water
piping (2 points)
Advanced utility tracking:
It is not anticipated that the project will attempt these points at this time.
Materials and Resources
Certified Tropical Wood - Prerequisite
The use of tropical wood in the building is not anticipated.
Durability Management - Prerequisite
The proposed development will take required interior moisture control measures such as
water resistant flooring at kitchens and bathrooms, drain and drain pan at washers.
Durability Management Verification:
The development will be inspected to ensure compliance with each measure relating to
durability management (1 paint)
Environmentally preferable products:
Out of the total of 5 points available, the proposed development anticipates achieving 3
points through the use of local production such as aggregate and sand for concrete and
through the use of reclaimed, bio-based FSC certified or recycled materials
Construction waste management:
The proposed development will reduce total construction waste 60% below the baseline by
recycling materials and diverting from landfills (3 points)
Indoor Environmental quality
Ventilation - Prerequisite
The proposed development will provide a whole -unit ventilation system that complies with
ASHRAE Standard 62.2 -2010
Combustion venting - Prerequisite
Any combustion appliances will be vented to the exterior, such as fireplaces, if they occur.
Carbon monoxide sensors will be provided in each unit.
Garage Pollutant Protection - Prerequisite
All air - handling equipmentond ductwork serving residential units shall be placed outside the
garage envelope. Shared surfaces between the garage and residential units shall be tightly
sealed.
Radon - Resistant Construction - Prerequisite
Since the proposed residential development is above a garage level, the development is
inherently resistant to the transfer of radon gas from the soil to the occupants.
Air Filtering - Prerequisite
MERV 8 air filters shall be used at recirculating air conditioning systems per ASHRAE 62.2-
2010
Environmental Tobacco Smoke - Prerequisite
The proposed development will prohibit smoking in all common areas. Any exterior
designated smoking areas, including balconies where smoking is permitted, will be located at
least 25 feet from entries, outdoor air intakes, and operable windows opening to common
areas.
Compartmentalization - Prerequisite
Each residential unit will be compartmentalized from another to minimize air leakage
between units by sealing penetrations, weatherstripping doors. Units shall be tested to
demonstrate compliance.
Enhanced Ventilation:
The proposed development will utilize an occupancy sensor or delay timer or automatic
humidistot controller or a continuously operating exhaust fan at the dwelling unit bathrooms
to control the exhaust fan (1 point) Each dwelling unit will have a balanced whole -house
ventilation system per ASHRAE 62.2 -2010 and will not exceed the standard by more than
10% (2 points)
Contaminant Control:
The proposed developmentwill have a pre - occupancy flush of the systems and airtesting.
During construction all permanent ducts and vents will be sealed to minimize contamination
from construction and upon completion of construction will be flushed with fresh air (0.5
points). Air testing will be performed at the end of construction to ensure that contaminants
do not exceed maximum allowed levels (0.5 points)
Balancing of Heating and Cooling Distribution Systems
The proposed development will test supply airflow and pressure balance the ductwprk and
HVAC system within each residential unit (2 points)
Enhanced Compartmentalization
It is not anticipated that the project will attempt these points at this time.
Enhanced Combustion Venting
The proposed development meets the requirements of this credit by not installing any
fireplaces of wood stoves (2 points)
Enhanced Garage Pollutant Protection
The proposed development will provide an exhaust fan on controls within the multkor garage
per ASHRAE 62.2 -2010 (1 point)
Low Emitting Products
The proposed development will use products for interior paints and coatings, flooring,
insulation and adhesives and sealants that have been tested and found compliant with the
California Department of Public Health Standard Method V1.1 -2010, using CA Section
01350,Appendix B, New Single - Family Residence Scenario, for emissions testing guidance (3
points)
No Environmental Tobacco Smoke
It is not anticipated that the project will attempt these points at this time.
Innovation
Preliminary Rating - Prerequisite
Design and construction team will conduct a preliminary LEED meeting in the early stages of
design to confirm and document LEED goals.
Innovation:
The proposed development anticipates receiving 2 points for innovation for measures such as
green cleaning program, acoustical performance, solid waste management policy, green
building education. Specific measures to be determined.
LEED AP Homes:
The project team will include a professional who is LEED AP Homes accredited (1 point)
Regional Priority
The proposed development anticipates receiving 3 additional points for credits which have a
regional priority.
