Windows That Help with LEED Certification

This is the third installment in our series called Energy-Efficient Windows 101 made possible by Marvin Windows and Doors. In the previous article, I discussed some of the product options available for your energy-efficient windows. For this article I want to focus on how Marvin windows contribute towards a home’s efficiency and LEED certification.

Windows and Energy Efficiency

Windows are a weak point in the envelope of a home and can make a home uncomfortable or drafty. However, that doesn’t have to be the case with products available from Marvin. Energy-efficient windows and doors can help reduce energy bills by up to 15%, according to the Energy Star website, and Marvin has more than 150,000 options for meeting or exceeding Energy Star requirements. Marvin has dual- and triple-pane windows, various low-E coatings, insulating gases like argon and krypton, and several choices of framing materials.

Windows and LEED Certification

As you probably know, windows themselves can’t obtain LEED certification but they may contribute towards certification for a project or home. Marvin windows may help contribute toward LEED-H points in several categories relating to energy performance, construction waste management, recycled content, regional materials,daylighting and views, and certified wood.

Try the Smart Performance Promotion

Marvin is running a Smart Performance Promotion giving one lucky homeowner $5,000 toward the purchase of new Marvin windows and doors. In connection with the promotion, the company published a collection of energy efficiency and other home improvement tips from Lou Manfredini, a homebuilder, contributor to the Today Show, and host of HouseSmarts TV.

Philips Has a New A-19 LED Bulb Design

Philips recently announced its next-generation A-19 bulb with a new design that contrasts sharply with the old yellow EnduraLED or the fluorescent L-Prize bulb.  The 60-watt replacement has a white appearance and uses 11 watts while putting out 830 lumens.  It will be available in both Soft White or Daylight color temperatures when released.

The bulb, which was designed to exceed Energy Star specifications, is being released in select New York locations of Home Depot this month.  It will also be available at with a roll-out expected in the beginning of 2013.

Philips continues to aggressively innovate in the LED lighting space.  Most recently, in October 2012, the company released hue, which is a smart, web-enabled LED lighting system that can be purchased for under $200.

Terralite is a Light New Insulative Cement

Portland-based Terra Bona Materials launched Terralite Cement at Greenbuild this year hoping to deliver a product that meets the energy-efficiency demands of the greater building science community.  Terralite is a “lightweight” product made with cement and an aggregate that includes expanded polystyrene.  Marketing materials claim the product is 20% of the weight of traditional concrete and, according to company president Terry Cotton, insulative with an R-value of 1.8 per inch.

The standard wall system is 10 inches thick, said Cotton.  And Terra Bona claims the new product is suitable for roofs, floors, and walls with “increased strength over cellular concrete, predictable mechanical behavior, significant sound control, and is fire resistant.

Terralite Cement can be purchased from selected distributors and also directly from Terra Bona Materials.  Distribution is currently being established in the Northeast USA, Midwest, and certain markets in Southwest and California, said Cotton in an email to Jetson Green.

This is an update to let you know of the status of the much-anticipated liquid-cooling LEDs from San Jose-based Switch Lighting.  SWITCH60, a 60-watt equivalent bulb that produces 800 lumens at 12 watts (clear) or 13.5 watts (frosted), is currently available at 350 participating Batteries Plus stores nationwide.  The SWITCH40 and SWITCH 75 will also be available later this month from Batteries Plus.

Energy Efficient Windows with Marvin

Over the years I’ve tried to fill in our coverage with more substantive, or how-to, information on topics relating to sustainable homes.  One topic that I’ve been itching to cover is energy-efficient windows, and I’m happy to announce that Minnesota-based Marvin Windows and Doors has agreed to share their expertise with Jetson Green for a series of articles loosely titled “Energy-Efficient Windows 101.”

Before jumping into this new series, I think it makes sense to introduce Marvin because I’m writing these articles based on information, research, photos, and videos that the company is sharing with us.

Marvin, as you may know, started in the lumber business in the early 1900s and gradually moved into making windows when trying to keep employees busy during the slower months of winter.  Now the company is a recognized leader in the window industry and retains its family roots with management made up of third and fourth generation members of the Marvin family.

The company makes windows to order with an extensive offering of clad colors, wood options, and hardware.  For more discerning customers, Marvin can make entirely custom window products and has more than 150,000 options for meeting or exceeding Energy Star requirements.  In short, this is a company that can focus on both design and energy efficiency.

If you have any window questions, leave a comment below.  The first article you’ll see relates to reading the rating label that’s placed on windows.

A DIY Portable Plug-in EV Charging Station

When you’re generating a surplus of energy — similar to these solar-powered homeowners — having a sporty electrical vehicle seems to make sense.  EVs and plug-in hybrids are becoming more popular, and I’ve seen all sorts of garage products for charging them.  Perhaps one of the more interesting models of late is this EVSE-RS Plug-in charging station by AeroVironment.  The portable, DIY charger just needs a dedicated 240-volt service and the station can be mounted and installed in a pinch.

That means the charging system may be used by renters, because it can be uninstalled and taken to a subsequent location.  Or, one could install an additional bracket somewhere else — perhaps a cabin retreat, work, or a friend’s place — and charge there too.

The AeroVironment product is “the preferred charging station of the Nissan LEAF, BMW Active-E and Mitsubishi i-MiEV,” according to claims in a product listing with Amazon.

The EVSE-RS Plug-In is SAE J1772-compliant and UL-listed for indoor applications.  It installs on a 30A “pigtail” wall plug, and the cord is 25-feet long to accommodate more than one vehicle.  Additionally, the charger restarts in the event of a power outage, has ground-fault monitoring, and protects against live power.  The MSRP is $1,099, but I’ve seen the price drop below that when listed on

Alpen HPP Buys Serious Windows Assets

If you’re a designer, builder, or future owner of a high performance home, you’ll probably be interested in knowing that fiberglass window products previously sold under the SeriousWindows brand will now be sold under the Alpen brand.  Boulder-based Alpen High Performance Products announced the purchase of assets including the fiberglass window and architectural glass operation from California-based Serious Energy, Inc.

Originally, the same window and glass business was founded by Robert Clarke and sold under the Alpen brand from 1981 through 2008, when Serious Materials (a former sponsor of this site) bought the business, according to a statement by Alpen.

There will be a period of transition, but readers can now get the 525 Series, 725 Series, and 925 Series through Alpen.  In the future, expect more green building products, too.  Alpen CEO Brad Begin said: “As we grow our business to include other highly energy efficient products, we feel that Colorado offers a rich pool of talent for innovative green product development.

LIFX is a WiFi-Enabled Smart LED Bulb

I’ve seen innovation in the smart LED space from the likes of Google and Insteon, but San Francisco-based LIFX Labs aims to reinvent the light bulb with a new, successfully-funded Kickstarter project called LIFX. The LED bulb is WiFi-enabled, energy-efficient, multi-colored, and controllable from an iPhone or Android. It will be available as Edison-type, bayonet cap, or downlight with everything necessary to work at home or in a business with a pledge from $69 on Kickstarter.

Philips L Prize LED Now Selling for $40

I was walking the aisles of Home Depot when I happened upon a screaming deal for the L Prize winning LED light bulb by Philips. This is the bulb, you may recall, that caused a national fuss over the reported price tag of $60. Turns out you can get the same bulb just five months later for the more reasonable price tag of $40 at Home Depot right now.

So I picked one up, and I’ll say this is one impressive bulb. The L Prize light bulb is brighter than the 12.5-watt AmbientLED with a similar yellow exterior.  I have several of these, and they’re excellent but not as powerful as the L Prize bulb.

The L Prize LED bulb uses only 10 watts of energy and delivers 940 lumens, 92 CRI, 2700 Kelvin, and 30,000 hours. In addition, the light bulb is dimmable and installs in a cinch with the Edison-type base. The one thing you may not like is the sealed plastic packaging it comes in. After you hatchet through that and recycle the remains, you’ll be well on your way to conserving energy with a nice dose of soft and warm light.
