Passive House Multi-Family 2015 (Weinberg Commons)

Posted on Thu, Jan 14, 2016

Last November UltimateAir was very excited to see the completion of one of the most exciting projects of 2015. Our friends at ZAVOS Architecture & Design finished their Passive House project named the Harry and Jeanette Weinberg Commons.

Located in Washington DC, Weinberg Commons represents a groundbreaking construction which is the first of its kind in the city. The project included three retrofitted Multi-Family buildings totaling 37 two bedroom apartments. The energy demands were kept particularly low by including R-41 dense pack fiberglass, triple pane windows, R-80 attic insulation, and of course Energy Recovery Ventilation units from UltimateAir Inc! Air changes per hour were tested below the Passive House standard of 0.60 ACH50 and the buildings are classified as “Zero Energy” ready (near zero energy use). PHIUS+ certification has been preapproved on one of the buildings, although all three were constructed to meet Passive House criteria.

Our team couldn’t have been more proud to be involved and working with ZA+D Architects has been an absolute pleasure. We hope to see projects such as the Weinberg Commons continue to make headway in the US building market. Yet again we witness a United States project far exceed the standard levels of energy efficiency which are commonly accepted in our industry. Great work to everyone involved and UltimateAir is thrilled to see what the future holds for ZA+D Architects and Washington DC’s hopefully blossoming addiction to Passive House building techniques! Special thanks to Architect Matt Fine for all his dedicated work on this project.

Commercial RecoupAerator Part of First Public School Passive House

Ultimate Air and the RecoupAerator have been featured in the Green Mechanical Contractor’s latest article, “The Building That Teaches- First Passivhaus U.S. School Building”.

This Franklin County, Virgina public school (K-12) is the first in the United States designed to Passive House standards and is equipped with the first ever  commercial RecoupAerator on the market!

Adam Cohen, LEED AP, co-owner of Structures Design Build LLC, has been involved with the CEED project (Center for Energy Efficient Design) since 2007.

When asked why his company selected the RecoupAerator over similar products he said, “There are no other products in the United States that have this type of cutting edge technology and efficiency. We also wanted to use a U.S. based manufacturer.”

Passive House design is a fabric first approach to low energy use, and the RecoupAerator lowers energy use with its high efficiency air exchanger. It’s all about numbers, Cohen says, revolving the three metrics: heating and cooling annual demand, air tightness and overall energy use.

The United States has a huge opportunity to improve our nation’s energy efficiency by adhering to Passive House standards for new commercial and residentail building projects. As a leading air filtration/ventilation system that uses less energy than most lightbulbs, the RecoupAerator is well positioned to serve this market.

Be sure to read the full article in the latest GMC, and learn more about how the RecoupAerator can be part of your next Passive House project.

RecoupAerator Installed in Massachusetts' First Passive House

Posted on Wed, Aug 10, 2011

passivehouseUltimateAir and the RecoupAerator have been featured in the Green Building Advisor’s latest blog article, “Matt Beaton’s Fill-Court Passivhaus Press." 

Built last September, a home in Shewsbury, Massachusetts has become the first certified Passive House in the Bay State. 

The Recoupaertor plays a vital role; because it's so energy efficient, it's contributed to Beaton's home's Passive House U.S. Certification, which was issued in July.

Passive House standards are growing in popularity throughout the United States because of the demand for environmental friendliness, long-term energy savings and exceptional indoor air quality. Because the Passive House is air-tight it is imperative that one has a quality air filtration system installed - and that's where we come in.

These homes will serve as a model for future homes and Ultimate Air was happy to be a part of this project and many more to come.
