Lennar and Dandelion Energy Bring Geothermal Energy To New Homes

Geothermal heating is coming to a new home community in Colorado, thanks to a partnership between Lennar and Dandelion Energy.

The homes in the Ken Caryl community in Littleton, Colorado – which will be both single family and townhomes – will feature individual home systems rather than a community-wide one for their geothermal heating.

Why it matters: Geothermal systems use the temperature of the ground to heat and cool the home, and will result in collective savings — around $30 million over 20 years compared to air-based systems, according to Builderonline.

Bigger Picture

wider use of geothermal pumps in Colorado could mean:

  • Lower energy bills for homeowners: high efficiency and grid-friendly performance reduces demand during peak times, helping all ratepayers.

  • Less strain on the state’s power grid: geothermal heat pumps have the potential to reduce electricity demand by up to 13% by 2050.

  • Tax credits and initiatives: the state of Colorado offers incentives, such as tax breaks and grants, that companies and individuals can take advantage of.

  • Job creation: Scaling GHPs to 36 million homes by 2050 will require a bigger, trained workforce and faster permitting and installation processes.

How it Works

Dandelion Energy, Lennar’s partner in implementing the geothermal systems, is installing them in two phases.

  1. Exterior work (drilling boreholes): Takes place on the site before construction on individual homes

  2. Interior implementation: Happens during the same phase during which workers would typically install a conventional air conditioner and furnace.

Bottom line: As major builders like Lennar embrace geothermal heating in new communities, homeowners stand to benefit from lower energy bills, valuable tax incentives, and a more resilient, future-ready home – all while helping ease the strain on the power grid.
