Fenestration |
This measure seeks to update fenestration U-factors and SHGC
prescriptive requirements. This includes angular SHGC
considerations similar to those contained in the overall
envelope approach. Evaluation should be conducted with
daylighting controls conditions. Evaluation will be
conducted with daylighting controls conditions. Key updates
to the life-cycle cost analysis will include an updated
database of available glazing products, their rated thermal
properties, and their costs. This will be compared with
ASHRAE 90.1/IECC. |

Daylighting |
This measure proposes to revise prescriptive minimum
daylight area requirement; revise minimum sidelit area
trigger for mandatory photocontrols requirement; re-evaluate
the cost-effectiveness calculations; examine possible
removal of the < 0.5 W/sf exemption; examine possible
removal of parking garage exemption for sidelit spaces;
re-examine the minimum effective aperture of 10% requirement
for sidelighting; re-evaluating the daylighting code to
simplify calculations. |

Indoor Lighting |
This
measure seeks to reduce retail lighting power consumption to
the extent it is technically and economically feasible. This
measure will also investigate controls in retail
applications. |

Outdoor Lighting |
This measure proposes bi-level controls for exterior parking
and a review of ASHRAE values. |

Sign Lighting |
This measure seeks to label signs as CA compliant based on
W/sf. It also seeks to simplify compliance verification
based on labels and revise W/sf limits based on new
developments in efficient sign illumination technology. |
This CASE is on hold for a
future code cycle. |
|
HVAC Controls and Economizing |
This measure proposes a rating method and certification of
durable code compliant economizers; proposes requiring
economizer on smaller AC along with compliant thermostats;
FDD prescriptive requirement with signaling capability to
thermostat or exterior gateway; spaces required to have
occupancy sensors are required to setback thermostat when
room is unoccupied; lab testing of RTU and economizer
control. |

Radiant Cooling |
This measure will develop and implement and test comfort
model in ACM so credit can be given to radiant cooling &
heating. |

|
HVAC Efficiency and Baseline |
This measure will develop a prescriptive base case based on
AHRI agreement and will develop compliance options for
evaporative cooling. |

Variable Speed Single Zone |
This measure will evaluate if it is cost-effective for
single zone air conditioners under 9 tons to be variable
speed. |

Cool Ducts |
The CASE will estimate the prevalence of exterior ductwork
on commercial buildings by a survey of existing buildings
using existing aerial and satellite photography sources in
order to extrapolate the savings potential statewide. |
This CASE is on hold for a future code cycle. |
|
Reduce HVAC Reheat |
This measure will examine three methods for minimizing
outside air-related energy use including acceptance testing,
feasibility of reducing outside air ventilation rates
immediately after economizer mode and determining thresholds
for cost-effective heat recovery between outside air and
exhaust air. Tradeoffs between outside air ventilation,
indoor air quality and productivity will be reviewed to
inform the discussion with the latest IAQ research and
current codes/standards issues. |

Outside Air |
This measure will examine methods for minimizing outside
air-related energy use. Tradeoffs between outside air
ventilation, indoor air quality and productivity will be
reviewed. |

Refrigerated Warehouses |
This measure will look at requirements for condenser fan
power, unitary condenser maximum W/Btu, fan efficiency
standard, evaporator sizing, and compressor staging and
acceptance tests. |

Supermarket Refrigeration
|
This measure is supporting an ARB refrigerant leakage
and GHG emissions study focusing on energy efficiency. The
focus is on supermarket sector larger than 8,000 square
feet. The measure includes DOE2.2R simulations of SBD
measures and will work with ICF on refrigerant
charge/leakage and methods to compare direct GHG (leakage
and refrigerant type) with indirect GHG (energy usage). |
