2016 CASE Measures

2016 CASE Measures

# Link to Measure Page Description
1 Residential Lighting Proposes requirements for high efficacy lighting in all residential new construction applications and eliminates exceptions that allow low efficacy lighting in combination with controls.
2 Residential High Performance Walls Reduces the prescriptive U-factor requirements for residential walls, which will reducing the amount of heat transfer through walls and thus reduce HVAC loads.
3 Residential High Performance Attics / Ducts in Conditioned Spaces (HPA/DCS) Proposes two alternatives to improve building thermal envelope and reduced HVAC distribution losses in residential buildings:

·        High Performance Attics (HPA) minimizes temperature difference between attic space and conditioned air being transported through ductwork in the attic.

·        Ducts in Conditioned Space (DCS) locates ducts and air handlers in the building’s thermal and air barrier envelope.

4 Residential HVAC Field Verification and Diagnostics Recommends revisions to existing refrigerant charging and verification procedures to reduce inefficiencies in residential HVAC equipment.
5 Residential Instantaneous Water Heaters Revise the prescriptive requirements for water heaters in single family homes and multifamily buildings with dedicated water heaters for each dwelling unit so the primary prescriptive pathway is based on a gas instantaneous water heater.
6 Residential Plug Load Modeling Proposed updated rulesets to use in the residential compliance software to estimate annual energy use of plug loads and lighting.
7 Nonresidential Indoor Lighting Power Densities (LPDs) Revises the lighting power allowances for nonresidential buildings so the values are comparable to those in ASHRAE 90.1-2013 where cost effective.
8 Nonresidential Lighting Controls: Partial-On Occupancy Sensors
9 Nonresidential Minimum Skylight Area Reinstate prescriptive requirement for minimum skylight area, which was inadvertently deleted during the 2013 code cycle, while maintaining overall simplicity of the daylighting requirements. The proposed requirement applies to large open spaces with high ceiling heights.
10 Nonresidential Lighting Clarification and Control Simplifies, clarifies, and provides compliance credit for inexpensive and effective lighting control strategies. Does not change the stringency of the building code.
11 Outdoor Lighting Power Allowance (LPA) Update the lighting power allowance requirements so they are based on LEDs as opposed to pulse start metal halides.
12 Outdoor Lighting Controls (Including Bi-level)
  • Expand existing requirement that outdoor lighting be equipped with motion controls that dim lighting when area is unoccupied to cover additional spaces including fueling stations and auto sales lots.
  • Revise allowed wattage reduction during unoccupied periods from 80% to 90%.
13 Nonresidential Opaque Envelope Revise the prescriptive opaque envelope requirements for all nonresidential and high-rise residential buildings.
14 Nonresidential HVAC Equipment Efficiencies (Based on ASHRAE 90.1) Update mandatory equipment efficiency requirements for space conditioning equipment so all equipment is least as efficient as requirements in ASHRAE 90.1-2013. Adds requirements for propeller or axial fan evaporative condensers and centrifugal fan evaporative condensers to harmonize with new requirements in ASHRAE 90.1-2013.
15 Direct Digital Control (DDC) (Based on ASHRAE 90.1) Requires most medium and large nonresidential buildings to be equipped with direct digital controls to the zone level.
16 Door & Window Switch Controls (Based on ASHRAE 90.1) Requires a mechanical switch that disables heating and cooling in perimeter zones when operable windows and doors are open.
17 Nonresidential Fan Efficiency Grade (Based on ASHRAE 90.1)
18 Elevators Lighting & Ventilation (Based on ASHRAE 90.1) Establishes lighting power density (0.6 watts per square foot) and ventilation efficiency (0.33 watts per cfm) requirements for elevators. When elevator is unoccupied, lighting and ventilation inside cab must shut off.
19 Escalators & Moving Walkways Speed Control (Based on ASHRAE 90.1) Speed must be reduced when the escalator or moving walkway is unoccupied
20 Nonresidential HVAC Economizer Modifications Clarifies existing requirements for Fault Detection and Diagnostic (FDD) systems for economizers and modifies economizer air flow and leakage requirements.
21 Nonresidential Thermally Driven Cooling Model Proposes adding a compliance options for the absorption chillers, adsorption chillers, and desiccant systems that would be available when using he performance approach. Recommends rulesets to add to the nonresidential compliance software.
22 Occupant Controlled Smart Thermostat (OCST)
23 CALGreen Commercial Kitchen Equipment
24 CALGreen Indoor Domestic Water Use Efficiency
