Green Building Myth: Green Products Are Hard to Find

Posted on March 23, 2010 by Alex Wilson in Energy Solutions

The last few weeks I’ve written about common myths of green building: that it has to cost more to build green, that green building is mostly about materials, and that green products don’t work as well as conventional prod

Getting Retailers and Manufacturers on Board with Green Building

Posted on March 23, 2010 by Michael Strong, LEED Associate, CGP in Business Advisor

I recently returned from speaking to over 400 sales people at two different sales conventions for two very different, yet very well-known companies. The first company is a multi-state regional retailer of building products. The second is a national green products manufacturer/installer. In both cases I was there to give my perspective on the green marketplace from a custom builder-custom remodeler’s point of view. It was my goal to show them just how different today’s green builder looks from the typical builder of the last generation.

Architects Discuss Passive Solar Design

Posted on March 19, 2010 by Christopher Briley in Green Architects' Lounge

It's time once again to share a drink with our two podcasting Maine architects, Chris Briley and Phil Kaplan. In the latest episode of their Green Architects’ Lounge series, Chris and Phil discuss passive solar design as they sip(SIP) Building panel usually made of oriented strand board (OSB) skins surrounding a core of expanded polystyrene (EPS) foam insulation.

Forget Vapor Diffusion — Stop the Air Leaks!

Posted on March 19, 2010 by Martin Holladay, GBA Advisor in Musings of an Energy Nerd

Last week’s blog answered some common questions about vapor retarders. This elicited a comment from Bill Rose, research director of the Building Research Laboratory at the University of Illinois in Champaign. “We might imagine a future in which the building code sections that address the vapor barrier would all go blank,” Rose wrote.

Green Building Myth: Green Products Don’t Work as Well as Standard Products

Posted on March 16, 2010 by Alex Wilson in Energy Solutions

The last couple weeks I’ve written about two of the common myths of green building: that it has to cost more to build green and that green building is mostly about materials. This week I’ll cover another myth: that green building products don’t perform as well as conventional products.

New HUD Policy on Appliances for NSP

Posted on March 15, 2010 by Peter Yost in Green Communities

Ladies and Gentlemen…really great news! You can now include washers, dryers and dishwashers in your rehab work for NSP1 and NSP2, and furthermore, they have to be Energy Star labeled.

Is anyone else celebrating? I know there are some celebrations happening in Maricopa County, Arizona! A big “Thank you!” to Ben Chao, the NSP Director for the Housing Authority of Maricopa County, who was instrumental in getting this energy efficient policy guidance issued.

More Whining About Green Building Programs

Posted on March 15, 2010 by Carl Seville, GBA Advisor in Green Building Curmudgeon

Following up on my recent post about LEED and other green programs, it occurs to me that the people responsible for creating and managing most green home certification programs have completely missed the big picture. I hope and believe that one day, through a combination of more stringent codes, legislation, and marketplace demands, we will reach a point where green building becomes the minimum acceptable standard.

Vapor Retarders and Vapor Barriers

Posted on March 12, 2010 by Martin Holladay, GBA Advisor in Musings of an Energy Nerd

Although building science has evolved rapidly over the last 40 years, one theme has remained constant: builders are still confused about vapor barriers.

Any energy expert who fields questions from builders will tell you that, year after year, the same questions keep coming up: Does this wall need a vapor barrier? Will foam sheathingMaterial, usually plywood or oriented strand board (OSB), but sometimes wooden boards, installed on the exterior of wall studs, rafters, or roof trusses; siding or roofing installed on the sheathing—sometimes over strapping to create a rainscreen. trap moisture in my wall? How do I convince my local building inspector that my walls don’t need interior poly?

This podcast series is excerpted from a two-day class called "Building Science Fundamentals" taught by Dr. Joe Lstiburek and Dr. John Straube, of Building Science Corporation.

Fraudulent Green

Posted on March 9, 2010 by Michael Chandler, GBA Advisor in Green Building Blog

Until recently, I hadn’t really given much thought to the builders in my town with the green leaves on their signs and the logos — “We were green before it was a color” or “Green since 1978” — who never show up at the green council meetings and won’t even certify to Energy StarLabeling system sponsored by the Environmental Protection Agency and the US Department of Energy for labeling the most energy-efficient products on the market; applies to a wide range of products, from computers and office equipment to refrigerators and air conditioners. because “it’s too expensive.” I was there once, belligerently misinformed, so I figure I can afford to turn the other cheek when I drive past a greenwasher's sign on the street.
