Joint Venture works closely with the highest levels of both the public and private sector to help Silicon Valley develop and manage our region's response to climate change.

We collaborate with regional government agencies, municipalities, supervisors, mayors, city councils, nonprofit organizations and community groups on a variety of projects to enhance sustainability.

Our public sector efforts focus on sustainability efforts in publicly owned buildings. On the private sector side, in 2009 Joint Venture created its Greenprint for Silicon Valley, a comprehensive strategy for leveraging innovations in clean technology to reduce greenhouse gases and make our region more sustainable while growing our economy at the same time.

Joint Venture’s climate initiatives consist of two distinct programs:

Public Sector: Climate Task Force

Since 2007, Joint Venture has convened representatives from many of the public agencies in Silicon Valley through the Public Sector Climate Task Force to develop strategies for reducing greenhouse gas emissions from public agency operations. The program focuses on inventories of greenhouse gas emissions from publicly owned buildings, setting goals for emissions reductions, and the creation of climate action plans. Through the Task Force, members share best practices related to their sustainability efforts, success stories and challenges, and embark on collaborative projects to achieve environmental goals.  Collaborative projects often include purchasing pools for green products and services, such as emissions inventories, tools, and renewable power.

Private Sector: Climate Prosperity Council

The Silicon Valley Climate Prosperity Council brings together businesses, executives and other private sector stakeholders from throughout our region and across multiple sectors to address climate change while growing our local economy. The Climate Prosperity Initiative focuses on four areas based on the California Global Warming Solutions Act and the opportunity to leverage local resources: renewable energy, building efficiency, clean, convenient transportation and green infrastructure. The initiative is guided by our Greenprint, and provides coordination among new and existing economic development and environmental initiatives.

Integration of EV Charging Infrastructure – ‘Use Case’ Scenarios

SEEDZ Projects > Electric Transport > ‘Use Case’ Scenarios

As companies in the Bay area expand their EV charging infrastructural deployments, they are looking to integrate this infrastructure with Energy Management and Demand Response capabilities.

Why This Matters

The primary benefit of a well-defined integration strategy for EV charging infrastructure is to reduce associated energy and demand charges for the hosting organization. It helps organizations effectively handle the most typical energy-related use cases they can expect to encounter, and determine how to best leverage an existing ecosystem of service providers. Also, it helps to identify and expose missing links where work still needs to be done.

Presented below are typical energy management ‘use cases’ for hosting organizations deploying and integrating EV charging infrastructure.

Scenario 1: Demand Response Scenario with Cloud-Based EVSE Control

This EV Infrastructure energy management use case involves a cloud-based EV charging network service provider. This enables EV charging infrastructure to react in apredictable/desired fashion when a DR event is called.

The EVSE service provider is integrated electronically with the utility to receive DR event signals, and then regulates charging at the hosting organization’s Electric Vehicle Supply Equipment (EVSE) according to DR rules pre-established by the host organization.

As shown above, the utility informs the cloud-based charging network about current demand related events on the grid. In response, the cloud-based service provider issues or fine tunes EV charging instructions via its cloud-based EVSE controller interface to charging stations, thus helping reduce the load for the building and addressing demand response for the grid. The charging network also keeps track of the vehicle status (for example, how much it is charged or how long it has been idle) and can apply local charging rules to further optimize the usage of electricity for the building and utility.

In this scenario the overall EV charging is controlled and managed by the third party charging network, which typically also manages authentication, notification and payment scenarios.

Scenario 2: Energy Management Scenario with Cloud-Based EVSE Control

This EV Infrastructure energy management use case describes how an office building or campus with an Energy Management System (EMS) can be integrated with EV charging infrastructure via a cloud-based EVSE control network.

As shown above, the building’s EMS directly interacts with the cloud-based EVSE controller. The EMS monitors overall energy use for the building or site (including EV charging). Based on the timing and cost of energy use (e.g. demand peaks, peak periods) the EMS sends signals to the cloud-based EVSE controller, to regulate EV charging load at the site according to specific charging instructions (e.g. reduce demand by a specified amount/time period). The EMS is also interfaced with the utility, thereby able to provide similar signals to the cloud-based EVSE when DR events are called by the utility.

Scenario 3: Energy Management Scenario with local EVSE Control

This scenario describes the use case for local controllers at one or multiple buildings on a campus site, to control EV charging and balance overall load.

The local controllers typically include a network connection with the building or campus for data, as well as connections for physical control of electric circuit(s). The building/campus Energy Management System interacts with the Utility and its DR/DM interface to receive demand response requirements as set by the utility, or by tracking local energy use, determines that EV load reduction is necessary. It then signals the local load controller to dial EV charging circuit capacity up or down, depending on what the building needs.

Why this Matters

The SEEDZ EV Infrastructure Interest Group has been established to provide a structured forum and meeting venue for local organizations and practitioners focused on setting up, managing and expanding their EV infrastructure.

This interest group addresses key practices, challenges for scaling and deployment, solutions, resources, collaboration strategies and other themes relevant to this growing community of Bay Area employers. The group is helping to facilitate development of a shared knowledge base and best practices for deployment of EV infrastructure at the workplace. The group serves as a good representation of demand for workplace EV charging, and real issues faced by these organizations in deploying and managing EV infrastructure. This, in turn, becomes a useful forum for periodic engagement with government agencies, utilities, and third party service providers (suppliers) regarding solutions and approaches that are needed in the market today.

The SEEDZ EV Interest Group meets bi-monthly, with meeting dates posted on the SEEDZ event schedule. For more information, please contact Michael Lenchner at This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

Integration of EV Charging Infrastructure – ‘Use Case’ Scenarios


Workplace EV Infrastructure Survey

SEEDZ Projects > Electric Transport > Workplace EV Infrastructure Survey

Why this Matters

Over just the past few years, a range of plug-in hybrid and full battery-electric vehicles have been brought to market by auto manufacturers. Silicon Valley has rapidly adopted this technology, and has the highest rate of EV ownership in the world. Deployment of supporting EV charging infrastructure has become a priority for many major employers in the area, local municipalities and businesses. As Bay Area companies rapidly add campus EV charging infrastructure for use by their employees, they are confronting a number of challenges including system planning and architecture, supporting business processes, organizational policies, integration with energy management systems, demand response with utilities, and interfacing with different systems and solution providers.

A key challenge is how major employers and other EV infrastructure stakeholders can deploy infrastructure that will survive and thrive into the future. A comprehensive survey was undertaken by Joint Venture in association with the Moffett Park Business Group. The survey involved local Bay Area employers that have invested in workplace EV charging solutions for use by employees. This survey focused on a diverse range of topics like current EV usage and charging stations, operations, trends, financial models, governance, third-party services integration, employee/driver engagements, and future plans. The goal was to identify common practices, challenges, and opportunities.

Key Survey Findings

The survey reveals some interesting data and trends:

  • EV Charging is mostly driven by employee demand, followed by corporate sustainability and branding efforts.
  • Almost all Bay area companies provide free charging to their employees and visitors. Usually charging stations are utilized for about 8 to 11 hours on weekdays. Ratios of EVs to charging stations range between 2-5 cars per station. Most stations are dual port and usually located in parking garages. Cord sharing is an increasingly common practice. EV services are usually offered over weekends as well.
  • Nearly 60% of these companies engage with third parties for cloud charging solutions and services, like Chargepoint, Blink Ecotality and EV Connect. None of the participants developed in-house solutions as alternatives.
  • Companies plan to increase the charging stations in proportion to their employee size.
  • Typical challenges include the number of charging stations that can be accommodated within limited areas, the need to better integrate energy management with Building Management Systems, storage, renewables, and utility DR/DM programs, EV sharing employee etiquettes, registration and activation delays, and a service infrastructure that manages all these aspects for companies.
  • In general organizations are looking for cost effective and efficient processes, organizational policies, smart charging programs, and solutions for integrating EV charging with building energy management, storage, renewables and utility DR/DM programs.

SEEDZ Projects - Electric Transport

SEEDZ Projects > Electric Transport

Advancing Vehicle Electrification and Charging Infrastructure

Within the Silicon Valley SEEDZ area, transportation currently accounts for 45% of all GHG emissions. So to meet state and local GHG reduction goals of 50-80% by 2050, transformation of our transportation infrastructure is vital. Electrification of vehicles and vehicle infrastructure will be one of the most critical elements in this transformation. Electric Vehicles (EV) in our area produce dramatically fewer GHG emissions per mile than comparable gasoline-powered vehicles – representing as much as an 80-90% emissions reduction opportunity.

Electric vehicles comprise a small but rapidly growing percentage of new vehicle registrations in our area, and propagation of EV charging infrastructure will be essential for maintaining this important trend. As Silicon Valley moves to broadly deploy EV charging infrastructure, a variety of challenges are emerging. How charging infrastructure will be most effectively and economically deployed throughout the community is a work in process. And there are many use cases – including charging at home, the workplace, in public places, and destination and corridor locations. SEEDZ project activity is focused on leveraging EV infrastructure deployment experience, plans, and investment among both private and public sector practitioners.
