The patented technologies behind Ecostella have been thoroughly tested by numerous utilities as well as the Building Performance Institute and Pearl.  All of them began their lives in the commercial space and have had tens of thousands of installations in well known brands like McDonalds, Taco Bell, Papa Johns, Hilton, Marriott, and many more.  Since that time, many more thousands of homeowners have made Ecostella

energy efficiency part of their homes.

Ecostella is backed by BPI - Building Performance Institute and Pearl; both leading organizations for the certification of home efficiency.  Our performance is 100% guaranteed and our reputation is unparalleled.  Ecostella is leading the way in energy efficiency across the U.S. by delivering real value to homeowners setting the standard for efficient homes. Ecostella is also supported by and made available with financing through the National Energy Investment Fund and The Awareness Group.

BPI is a national standards development organization for residential energy efficiency and weatherization retrofit work. As an independent, not-for-profit organization, we bring together leading building science experts from across North America to develop our standards using a consensus-based process.  BPI functions as a vital connection between contractors, technicians, training organizations, and programs to ensure the entire home performance and weatherization workforce is following the same strict protocols.    Pearl Certification is the standard for homes that go above and beyond to keep you comfortable, healthy and saving energy. A home like that is valuable to you – and to future homebuyers. With Pearl Certification, you get the guidance and tools you need to increase your home’s value and maximize its price when it’s time to refinance or sell.

Pearl’s certification system enables home buyers to see and understand the value of a home’s high-performing assets when the home is sold. Research from across the U.S. shows that third-party home performance certifications like Pearl’s add an average of 4% to the sale price of high-performing homes, compared to similar homes lacking these assets. An appraiser-authored study on Pearl Certified homes showed a 5% premium when the homes were marketed correctly. Pearl is the only private certification firm to sponsor the U.S. Department of Energy’s prestigious Home Performance with ENERGY STAR program. Pearl is a National Association of Realtors (NAR) Reach Accelerator company.


The below represents a monthly comparison of energy consumption and device performance. This study was performed to ASHRAE standards and conforms to utility guidelines for measure and verification and performance monitoring. Devices installed include Stella Prime, Stella APC and SynCat360 along with a full HVAC system tune up.

Individual Technology/Product Data

Below are a few excerpts from utility and/or engineering case studies for our three core efficiency technologies. Complete studies and documents are available up on request

Stella Prime - 24V Variable Fan Timing and Compressor Control

Stella Prime has been evaluated by numerous utilities across the country and has been performing successfully in thousands of commercial applications and tens of thousands homes.

The figure below is an excerpt from a utility study performed in conjunction with the CA Energy Commission and illustrates the benefit of extending HVAC fan run-times.

Stella APC - Adaptive/Variable Fan Speed Control

Stella APC developed with grant funding from the Department of Energy and has been so effective that HVAC system manufacturers are beginning to incorporate variable speed fan technology into their newer more expensive systems; validating this tech even further.

Below is an excerpt from a study performed on a university in North Carolina residential housing unit which shows a 40% decrease in overall fan cycles. This is significant because the initial energy consumption on start up for the fan can be 6 times the energy consumed during operation.

The data below was taken from of DOE study which showed an overall energy savings of 22% during winter months and 38% during summer months.

SynCat360 - Synthetic Catalyst Additive

SynCat360's technology has been utilized for two decades and has been tested extensively in numerous applications from refrigeration to HVAC.

Siemens Energy conducted a comprehensive study of the SynCat360 technology and deployed the product in 435 HVAC systems serving the building. These results were tabulated and reviewed; an average electrical reduction of 28% was observed to be associated with the SynCat360 technology.

Another study was completed by MaraBrite Engineering the conclusion of which found energy savings ranging from 21-24%. An excerpt from that study is below.
