The challenge

To be part of a competitively-selected cohort of startup and/or seed stage ventures who offer products or services, including smart home and building technologies, aimed at reducing fossil fuel use and greenhouse gas emissions in buildings, enable better integration of distributed resources and smart building technologies, increase resiliency and/or support demand management strategies that avoid peak time energy usage.

The goal for the DeltaClimeVT Energy2020 program was to help move us toward a zero-carbon future through better integration of distributed resources and smart building technologies and to help Vermont’s utilities harden the distribution network against outages.

We were particularly interested in technologies that have wide potential applicability and enable low and moderate-income populations and multi-family building residents to participate in the low-carbon economy.

Examples of technologies or services could include but were not limited to:

  • Innovative heating systems, such as advanced wood heat, geothermal heat pumps, advanced air to water heat pump systems or heat pump technology with integrated storage or demand response controls;
  • Building controls that align with utility demand response signals;
  • New weatherization materials or building construction materials that have lower embodied carbon footprints and help reduce energy use;
  • Smart thermostats, EV charging supply equipment and other devices to include storage that could align with utility demand response signals;
  • Fuel cell technologies;
  • Innovative solutions to bring reliable connectivity (ex. broadband) to rural areas to enable behind the meter technologies;
  • Innovative financing models for technologies and services (e.g. innovative loans, on-bill financing, heating as a service)
  • Any other technology or service that reduces energy use and greenhouse gas emissions in buildings and/or supports demand management in buildings.

Vermont offers entrepreneurs the opportunity to access services, networks and growth capital, in a state known for its high quality of life. Vermont was recently ranked the #1 state to move to thanks to growing professional opportunities. DeltaClimeVT programs are held in Burlington, the state’s largest city, which sports a vibrant entrepreneurial ecosystem supported by:

  • innovative companies willing to pilot new, groundbreaking products and services
  • growing incubation and co-working infrastructure
  • an active lending and investment community
  • like minded companies eager to help and partner
  • regular entrepreneurial meetups and events
  • robust technical and professional services
  • multiple higher educational institutions

The undesirable fact that climate change will have a large effect on the way we all live our lives and how we interact with each other has created an opportunity for innovative entrepreneurs to develop products and services that aim to mitigate the risks and deal with the consequences of climate change.
