New LED Lighting Styles Launched by Barn Light Electric

Modern Kitchen LED Red Cherry Aero

Barn Light Electric has announced its launch a a new line of lighting fixtures that utilize innovative LED technology from Cree, Inc., an innovator in LED lighting.

Barn Light is combining its vintage-styled lighting with energy-efficient, low-maintenance LEDs. Cree provides a proprietary TrueWhite® technology that transmits a warm light similar to traditional incandescent bulbs.

“While LED lighting is hardly new, many people are unclear on all of the benefits of using LEDs,” said Scott Dodson, Project Manager and LED Liaison at Barn Light Electric. “When you invest in LED lighting, it may cost more up front than incandescent or fluorescent bulbs, but you’ll start saving money, through reduced energy consumption and lower maintenance costs, the minute you flip the switch.” Read more »

Low-Carbon Concrete Products to be Developed by Atlas Block and CarbonCure

Atlas Concrete Carbon Neutral Block

Atlas Block, a manufacturer of concrete products based in Ontario, has signed a licensing agreement with CarbonCure, an emerging leader in science-based concrete technology for green building, to manufacture low-carbon concrete that will significantly reduce the carbon footprint of the concrete industry.

Several months have been spent testing the bolt-on technology from CarbonCure at the Atlas Block Hillsdale plant. The method sequesters carbon dioxide into the concrete during the manufacturing process. CO2 waste is consumed during concrete production to transform it into solid limestone, thus creating a better concrete product. Read more »

13 Reasons to Plan a Foam-Free Enclosure

Spray foam has been the subject of much discussion in green building circles.  Whether the concern is installation safety or global warming potential or better energy performance, it seems there’s no shortage of debate.  Along these lines, the guys at 475 High Performance Building Supply, a Brooklyn-based provider of products for high-performance projects, have a list describing 13 ways foam fails, starting with the “dangerous toxic ingredients.

Wood Fiber Insulation Arrives in the USA

Looks like wood-fiber insulation board is coming to the USA, according to a Greenbuild update on Green Building Advisor.  Agepan THD is the name of the product and it’s used as exterior sheathing for walls and roofs.  Agepan boards connect in tongue and groove fashion and insulate to R-5.74 per panel (2″ x 74.5″ x 23-5/8″).  The material has a high permeability (18 U.S. perms) and can be used in a wall assembly to dry to the exterior.  It’s offered through Washington-based The Small Planet Workshop Store.

Omni Block is an Insulated Concrete Block

I noticed in Dwell‘s Prefab edition that one prefab was partially built with an innovative concrete masonry unit (CMU) by Nevada-based Omni Block.  Omni Block is a structural CMU filled with Expanded Polystyrene inserts.  Walls with Omni Block can be finished or, in the case of the Simpatico project (see below), left exposed for a modern interior or exterior.  The manufacturer says the material is fire resistant, durable, and thermally efficient, and the blocks come in colors or with special aggregates.
