A.
Durability of Materials.
B.
Shade, Cooling and Energy Conservation Requirements. New development shall incorporate at least two of the following thermal design/energy conservation measures:
1.
"Cool" surfacing materials and roofs with high reflectivity values.
2.
Adequate openings and interior ventilation, as well as ventilation corridors between buildings and public spaces.
3.
A combination of building placement, vegetation, and structural shade features to provide heat mitigation and improve human thermal comfort. Structural shade features may include ramadas, pergolas, and canvas shades and other built structures can provide varying shade amounts.
4.
Fixed overhangs over all south-facing windows in combination with window coverings on south and west exposures.
5.
Building orientation, including the incorporation of courtyards, to provide shade and passive cooling.
6.
On buildings sides with high solar exposure, improvements such as shade screens, window glazing, and less than 50% glass on east and west walls.
7.
Use of high-performance building envelopes, including insulation of floors, walls, and ceilings that exceed California Code of Regulations Title 24 standards, use of low-e glass and other high-performance curtain wall or glazing systems.
8.
Alternative means to address interior thermal regulation such as installation operable windows to allow cross-ventilation, celling fans, and alternative heating and cooling systems such as heat pump or on-demand water heating.
9.
Employment of heat recovery ventilation within residential or nonresidential buildings, which rather than venting warm exhaust air outside, captures the exhaust air and uses it to preheat incoming air.
10.
Use of energy efficient appliances and lighting that meet, at minimum California Green Building Code Tier 1 standards.
C.
Sustainable Materials and Construction Practices. New development and redevelopment/renovations shall consider the following:
1.
Sustainable local and renewable building materials should be used and verified whenever feasible.
2.
Projects shall strive to reduce or eliminate waste during design, construction, operation, and end of life in order to conserve natural resources.
3.
The use of low-carbon cement is encouraged whenever feasible and/or the use of alternative materials.
4.
Consider prefabricated building/structural components when feasible.
5.
Leftover material stock should be recycled, donated, or returned for alternative use at the completion of construction.
D.
Electrification. All new buildings shall be all-electric ready, including providing for sufficient capacity in the installed utility service, dedicated wiring, reserved electrical breaker space, and a space large enough for future electric appliances or equipment. All new development shall meet California Green Building Code requirements.
E.
Water Conservation/Quality. The following guidelines are recommended to minimize water use and/or improve water quality for all new development and redevelopment/renovations:
1.
Use high-performance water fixtures that reduce water consumption and reduce demand on the water supply and the amount of wastewater entering the wastewater system.
2.
Design streets, parking lots, and building surfaces to collect stormwater run-off using low impact development techniques, such as bioswales or other biofiltration systems.
3.
Capture rainwater in cistern or other devices to supply water for landscape irrigation during dry months or channel rainwater from building rooftop drains to landscaping in common areas.
F.
Affordable Unit Design. Affordable units and market rate units in the same development shall be constructed of the same or similar exterior materials and details such that the units are not distinguishable.
G.
Universal Design. For residential projects with at least 10 dwelling units, 10% of the units must adhere to the following principles of Universal Design:
1.
At least one entrance without steps and a flat threshold.
2.
Living space on one floor or stair landings big enough to accept lifts.
3.
Wide interior doors (32-inch clear, typically provided with 36-inch door), hallways, and alcoves with 60-inch by 60-inch turning space at doors, in kitchens, and dead ends.
4.
At least one bedroom and one bathroom must be located on the ground level. A family room or den may satisfy this bedroom requirement if a sleeping structure (such as a bed, futon, hideaway, or Murphy bed) can be placed in the room and if the room complies with provisions for emergency escape and rescue and smoke alarms in the California Building Code (CBC).
5.
At least one accessible route through the hallways consistent with the requirements of CBC Chapter 11A from the accessible entrance of the dwelling unit to the primary entry level powder room or bathroom, a common use room, and the kitchen if located on the primary entry level.
6.
If on the primary entry level, miscellaneous areas or facilities (such as a patio or yard, laundry room, or storage area) for the dwelling must have an accessible route to and from the accessible entrance, either through the dwelling unit or around the dwelling unit.
7.
A 30-inch by 48-inch clear space at appliances and fixtures in bathrooms and kitchens.
8.
Flooring throughout the residential dwelling unit consistent with CBC Chapter 11A.
9.
The installation of all receptacle outlets, lighting controls and environmental controls through the balance of the residential dwelling unit must comply with CBC Chapter 11A or applicable provisions of the California Electrical Code.
