'Pioneering' Crossway Passive House featured on 'Grand Designs'

Ben Welter - Thursday, July 30, 2015

Crossway Passive House

Renowned architect Richard Hawkes' Crossway Passive House, completed in 2009, gets another look on this week's episode of the British TV series "Grand Designs."  

"The iconic feature of this pioneering house," writes Building Construction Design, "is a scarily thin soaring arched roof. Made by gluing clay tiles together using Plaster of Paris without any formwork, this in turn supports over 100 tons of soil which is now host to a thriving wildflower habitat."

The 3,000-square-foot home is packed with energy-efficient technology, including 580 liters of phase change thermal storage and DuPont Energain PCM panels in the south-facing rooms.

Vertellus doubles alkane production capacity at Michigan plant

Ben Welter - Thursday, July 16, 2015

Vertellus, a manufacturer of specialty chemicals, has doubled alkane production capacity at its Zeeland, Mich., hydrogenation plant. The company expects alkanes to be one of several innovative chemistries supplying a growing global market for phase change material.  

"North America’s competitive feedstock costs resulting from low natural gas prices are helping drive Vertellus’ alkane production efficiencies," the company said in a news release. "The company initiated the Zeeland upgrades in 2014, the same year it commercialized hexadecane (A16T). With added alkane production capacity in place, Vertellus will develop eicosane (A20T) in its 2015 pipeline. Octadecane (A18T) represents the company’s largest category of alkane production due to its ability to absorb and release heat close to the human body temperature."
