City of Santa Monica: Sustainability

Environmental & Regulatory ContextState Goals• Single-family NC to be Zero Net Energy by 2020• Commercial NC to be Zero Net Energy by 2030• 12,000 MW from distributed generation by 2020• Increase energy efficiency from existing buildings by 50%• Increase renewable energy to 50%City Goals• Reduce communitywide emissions:

– 50% below baseline by 2030– Carbon neutral by 2050

• 7.5 MW installed solar capacity by 2020

Mandatory Solar

1. Single Family Homes1.5 Watts per Square Foot

2. Multi-Family/Commercial2 Watts per Square Foot (building footprint)

Reach Code: ZNE1.Santa Monica historically implements more

progressive energy requirements than theState

2.California will require ZNE for all newResidential construction in 2020

3.Combined with current solar requirement,energy measures beyond code are minimal

4.Santa Monica homes will be more valuable,more resilient

Energy Code History

Reach Code

All new buildings shall bedesigned to use xx% less energythan required by the CaliforniaEnergy Code (Title 24, Part 6)

Reach Code: ZNE

ZNE – California Codes• A ZNE Code Building is one where:

• the value of the energyproduced by on-site renewableenergy resources is equal to thevalue of the energy consumedannually by the building,

• at the level of a single “project”seeking developmententitlements and building codepermits,

• measured using the CaliforniaEnergy Commission’s TimeDependent Valuation metric.

• A ZNE Code Building (residential) is a building that hasa Energy Design Rating of Zero (aka TDV Zero)• Score is based on CEC approved ACM calculations and

assumptions• Includes energy used for space heating, space cooling,

water heating, lighting, plug and appliance energy use• Uses a reference home compliant with the 2006

International Energy Conservation Code (IECC)• Goal is to better align with RESNET

• Energy Design Rating =(TDV Proposed/TDV Reference) x 100• Will be calculated by CEC approved residential software

ZNE – California Codes

2016 CalGreen Efficiency Tiers

• Tier I: 15% lower energy than 2016 base code• Regulated end uses only – space heating, space cooling and water heating

• Tier II: 30% lower energy than 2016 basecode• Regulated end uses only – space heating, space cooling and water heating

• Tier III (aka ZNE Tier): meet Tier II energyefficiency + have EDR = 0• Through combination of EE and renewables

Is It Cost-Effective?

• Cost-Effectiveness Analysis – Accordingto CEC’s Life-Cycle Cost methodology

• Energy savings benefits using TDV andcost data specific to Climate Zone 6

• Benefit-to-Cost Ratio• Performed by CEC/CPUC funded process

Compares the costs and benefits over the life of the system

1) Average consumer savings - evaluates cost‐effectiveness forresidential and commercial building owners on average

2) Market‐segmented savings - evaluates cost‐effectiveness based ontheir specific retail rate and annual electricity consumption

Life‐cycle costs and benefits are evaluated over a 25‐year horizon. Thelife‐cycle costs of PV are evaluated over a 20‐year period, the standardduration of power purchase agreements (PPAs), followed by a 5‐yearperiod of no additional costs to the customer.

factors• Reduced infiltration• Cool roofs• Radiant heating and cooling• Heat pump water heaters• Combined hydronic heating• Compact domestic hot water

piping• HVAC design changes• Photovoltaics

Non-Residential• High efficacy lighting• Advanced lighting controls• Institutional lighting tuning• Increased fenestration U-

factors• Increased envelope insulation• Cool roofs• Heat pump water heaters• HVAC design changes (e.g.,

fan efficiency, dedicatedoutside air systems, heatrecovery)
