Who We Are
And Why It Matters
Efficiency First California (EFCA) is a non-profit trade organization that represents and promotes clean energy contractors in California. For over 20 years, we have helped contractors like you succeed.
EFCA is directly involved in state policy discussions. One of our core responsibilities, as a trade organization, is to help contractors be aware and involved in state energy policy.
Policymakers on the local, state, and federal levels often reach out to us directly to better understand the contractor’s perspective. The contractor’s perspective is crucial in policy discussions. We listen to and advocate for you, the contractor.
We partner with industry stakeholders who share our common goals. Working collaboratively, we have been able to influence policy on a large scale.
We want to help you grow your business. Our monthly blog and advocacy update help you make well-informed decisions about the future of your business. We represent your best interests for sustainable, fair, and unbiased business models. We have an extensive list of industry contacts.

The Voice for Energy Efficiency & Clean Energy Contractors
training & events for clean energy & energy efficiency
Energy Management Systems (EMS) with HVAC Controls (2 Part Series)
Series Description Part 1 of 2 - September 23, 2025 (9:30am - 11:30am) Part 2 of 2 - September 24, 2025 (9:30am - 11:30am) Getting the most energy savings out of your HVAC requires building systems to be capable of adjustment, such as variable speed drives or demand limiting, as opposed to simple on/off control. However, these strategies often add a higher level of complexity making it more challenging to keep persistent energy savings over time. Energy Management Systems and
Next Generation Passive Solar
Event Description We all learned the principles of passive solar design in school – south facing orientation, strategic windows, thermal mass, etc., but the old rules don’t apply in the same way. Modern buildings should still incorporate passive strategies, including daylight and ventilation, but they need a new spin on the implementation to account for improved insulation, prevalence of high-performance glazing, and efficient HVAC systems and lighting. Learning Objectives Review passive thermal design strategies including basic climate analysis and guidelines
Avoiding Main Panel Upgrades – Part 1: Demystifying & Calculating Loads on Your Main Panel (Webinar)
Description: This is part 1 of a 2 part class. Understanding your main electrical panel is essential for the transition to an electrified home. This session simplifies the components of the main electrical panel in a home. It will explain prescriptive and performance-based load calculations to determine whether a main panel upgrade is necessary. It also covers load management techniques and how power-efficient appliances can reduce demand on the electrical panel. Learning Outcomes: As a result of attending this class
Advanced Thermostat Solutions: Best Practices and Trends
Join us for an in-depth look at how communicating thermostats are shaping the future of HVAC performance and customer satisfaction. In this session, experts from LG and Daikin will break down the latest in thermostat technology, going beyond basic programmable and schedulable controls to explore demand response-enabled systems, built-in Wi-Fi capabilities, and new control strategies. We’ll also highlight emerging technologies, best practices for contractors, and industry trends and concerns that every professional should be aware of. Don’t miss this opportunity

California Contractor Advocacy
Building a clean energy future for all
Efficiency First California is actively engaged in California policy. We monitor communications from the California Energy Commission and the California Public Utilities Commission. When needed, we provide feedback to ensure regulations and policies consider the contractor’s role and the implications proposed regulations may have on contractors.
Your feedback as a contractor is critical for our efforts. We encourage your participation in policy discussions. We feel it is our role to represent your perspectives.

Program Administrator for Sacramento Municipal Utility District
EFCA leads the way in rebate program management

We have been a key player in providing utility support services to different entities like TECH, SGIP, and PG&E, particularly as a program implementer for Sacramento Municipal Utility District (SMUD) incentive programs.
Our success has made EFCA a valuable resource for rebate program designers and implementers. We openly share our processes with others so they can also create successful programs, with the ultimate goal of making things easier for contractors (and homeowners).
