What are the spatial patterns of high and low net solar potential across the County?
As Los Angeles County seeks to meet regional and statewide climate and sustainability goals,
solar power and Zero Net Energy (ZNE) capable buildings are gaining policymaker attention. With a growing population, increasing energy demand, and a critical need for reducing greenhouse gas (GHG) emissions, investing in renewable energy and energy efficiency has never been more important. Electricity production alone accounts for 32% of total carbon emissions in California, the second-largest GHG-emitting state in the country (CPUC, 2008). In response, the state and public utilities have set a goal for ZNE residential construction by 2020 and ZNE commercial construction by 2030.

Mapping Net Solar Potentialof Building Types in LA County
This project offers insight into how cities throughout LA County can target high potential ZNE buildings using high-resolution energy consumption data. The maps explore the relationship between annual rooftop solar potential and current energy consumption among building types and sizes for each city in LA County. Because fine-scale energy consumption data is publicly inaccessible, this project is the first exploration of ZNE building potential based upon the LA County Solar Map and address-level energy consumption information. The combination of these powerful datasets allows for an exploration of geographic and building type net solar potential among the 88 cities in LA County.
METHODOLOGY
(1) LA County Solar Map & Planning Tool(2) LA County Energy Database from the California Center for Sustainable Communities at UCLA (Both datasets contain parcel-level data)
STEP ONE : COMPARING TWO DATASETS
• Annual electricity (kWh) consumption and solar PV potential for five building types and seven building size categories spatially summed and compared for each city in LA County
• Identified building types and sizes with highest net solar potential
• Ran entire process as python command in a spatially-enabled PostgreSQL database with CSV table output
STEP TWO : SPATIAL SUMMING
STEP THREE : MAPPING
mapped using ArcMap 10.2

High resolution energy consumption data allows for a more dis-aggregated view of high potential zero net energy building types throughout Los Angeles County.CPUC 15/15 privacy guidelines limit the ability to analyze high resolution data in many cities. These guidelines preclude analysis for geographies with accounts using more than 15% of the total consumption, or geographies with less than 15 accounts. Northern and eastern regions of Los Angeles have highest net solar potential.

• Residential buildings are largely high potential opportunities for net positive solar, particularly for single family residential and multi-family residential in northern and eastern regions.
• Though industrial uses tend to use comparatively more electricity, Map 4 shows the high level of positive net potential in many cities with industria facilities. This building type is the only category for which the city of Los Angeles is net positive.
• LA County is rife with solar resources that in some cases exceed annual electricity consumption.
