Help us make housing more affordable and sustainable for low-income families, seniors, and disabled individuals. Donations will be leveraged to upgrade affordable housing properties using green and clean energy technologies to serve communities, provide economic mobility, and fight climate change.


"ICAST is synonymous with professionalism in every sense of the word. From the energy audit that was conducted, they are presenting us with several options which will enable us to upgrade our facility and make better use of our funds which is a win-win for us."
-- Frank Proffer, Senior Pastor, First Baptist Church, Pueblo, CO

"ICAST was able to include not only energy improvements for my building, but also other enhancements that have totally changed the look and feel of my building."
-- Kevin Liddy, Member at Reef Point Apartments IV, LLC

"Once the retrofit was completed, we started saving money on energy cost, which means more money can be spent towards our organization's mission."
-- Paul Major, President and CEO of Telluride Foundation

"For a project of this magnitude, ICAST did a great job. Their workers took care of everything in a professional and efficient way."
-- Audry Guthrie, Property Manager, Eagle Point Apartments

"Although it was difficult to work around the children when school was in session, the auditors and technicians were very respectful and did a great job!"
-- Greta Shackelford, Little Red Schoolhouse

"The residents have been very happy with the heat and insulation in each of their apartments. And when our residents are happy, we are happy. They also seem to like the new lights in their bathrooms too. Again, happy residents is a good thing."
-- Natalie Bowman, Executive Director, Rifle Housing Authority

"These new LED lights allow my grandchildren to safely play outside into the evening, and I can leave my apartment at night without worrying who may be lurking in the corridor."
-- Greenleaf Apartment Resident


ICAST's mission is to provide economic, environmental, and social benefits to communities in a manner that builds local capacity.

Background Statement

ICAST was founded in 2002 as an initiative in the Engineering School at the University of Colorado at Boulder. Shortly after, ICAST registered as a 501(c)(3) nonprofit social enterprise and moved to the Colorado School of Mines campus before establishing its Lakewood, CO office in 2007. Initially, ICAST projects focused on the the establishment of a successful solar power company, as well as several international job skills training programs. Following these projects, ICAST's main focus became centered around the U.S. multifamily housing sector, reducing energy and water consumption by retrofitting both income-eligible and market rate multifamily housing. Despite the varied and nonlinear initiatives ICAST has pursued, the nonprofit has always stayed on the path of its mission. In the pursuit of this mission, ICAST has innovated, collaborated, and creatively adapted to maximize community impact.
