Demand Responsive
Thermostatic Controls |
This
measure evaluates the feasibility of requiring programmable
thermostats in residential and nonresidential buildings that
can be easily
upgraded to have demand response capabilities. |

Demand Responsive Lighting
Controls |
This measure is developing
specifications to define lighting control systems with
adequate demand response capabilities and an acceptance test
to ensure DR equipment functions as designed. |

Water Heater Standing
Loss |
This measure is developing
requirements that will reduce standby losses from natural
draft circulation up the flue in natural gas water heaters.
Mandatory requirement for
water heaters to be equipped with flue dampers or have force
draft design. |

PIER Study Acceptance
Testing |
Project will take the results
of a PIER project investigating acceptance testing
requirements, propose strategies to simplify tests or
testing procedures, and/or propose new tests as appropriate,
and support the recommendations through the CEC rulemaking
process. |
Acceptance Testing and Design-phase Commissioning |
|
Commissioning/RCx
Acceptance Tests |
Propose new acceptance tests
from experience with retro commissioning or commissioning
programs that have identified common failure modes that can
be identified with a short directed acceptance test. |

PV ready buildings |
Require non-residential
buildings to be PV Ready by requiring pre-piping conduit
between service panel and roof, and/or requiring a minimum %
of roof space be left free for PV, and/or other structural
or rooftop configuration measures. |
Solar Topics |
|
Cooling towers |
Investigate appropriate W/Btu
of heat rejection appropriate for longer hours associated
with process cooling, VSD control of fans. Add closed
circuit fluid coolers to table 112-G. Provide prescriptive
minimum approach based on minimum efficiency, hours of use
and climate. |

Air compressors |
Develop requirements for
industrial plants with compressed air systems to implement
system control mechanisms on multi-compressor systems. |
Process Air Compressors, Boilers, and Water Heaters |
|
Boilers |
This measure will investigate
draft damper or forced draft, parallel positioning and O2
trim control, and VFD for large boilers |
Process Air Compressors, Boilers, and Water Heaters |
|
Solar water heating |
Increase the prescriptive
requirement for residential solar water heating when
electric resistance water heating is used, and implement
requirement for commercial building types where electric
water heat is used. Introduce an hourly solar thermal model
for solar water heating. |
Solar Topics |
|
Boiler temperature reset
controls |
Remove the current chilled and
hot water temperature reset controls exception in section
144J to apply only to hot water systems with VSDs, rather
than all hydronic systems with variable flow |
