- Homebuilder Lennar to Build Largest Solar Homes Development in U.S. – According to a deal with Sacramento Municipality Utility District (SMUD), Lennar will build 1,254 energy-efficient homes with solar power systems as a standard feature in 11 communities in the Sacramento area. SMUD will provide a maximum of $10.9 million in incentives and Lennar will receive the rebates after homes are constructed. That’s about $8,700 per home for solar.
- Philips Supports a New Call-to-Action to Adopt More Energy-Efficient Lighting in North America – A congressional coalition of energy efficiency advocates announced plans for proposed legislative action for a major shift toward incorporating high-efficiency lighting technologies in home and office settings. The call-to-action was introduced by Philips Lighting North America, the Lighting Efficiency Coalition, Congressman Don Manzullo (R- Ill.) and Senator Mark Pryor (D-Ark.) to support the adoption of more energy- efficient lighting in North America.
- DOE Selects 13 Solar Energy Projects for up to $168 Million in Funding – U.S. Department of Energy (DOE) Secretary Samuel W. Bodman announced the selection of 13 industry-led solar technology development projects for negotiation for up to $168 million (FY’07-’09) in funding, subject to appropriation from Congress under President Bush’s Solar America Initiative. These projects will help significantly reduce the cost of producing and distributing solar energy.
I ran into a pretty thorough article on green roofing and wanted to pass it along to readers. There’s a growing interest in green and vegetative roofs, although one may not be perfect for every application. That said, there are numerous benefits and advantages to having a green roof.
Simply put, here are the benefits: (1) opportunity to utilize wasted or otherwise unused space, (2) reduction of storm water runoff, (3) mitigation against urban heat island effect, (4) airborne toxins are taken out of the air with oxygen getting released, (5) reduction in peak load (lower energy costs) for the building with the green roof, (6) longer roof life, and (7) considerable insulation from noise pollution.
Here are some of the drawbacks: (1) could cost up to twice as much as a conventional roof (but will offer a payback of 5-10 years in energy savings), (2) could be difficult to get zoning approvals depending on the sophistication of the approving authority, and (3) will constrain some types of architectural expression.
[Run time = 26 min.] I’ve posted about LivingHomes here, here, and here. Well, Steve Glenn is the company’s CEO and Founder and he has some interesting things to say. If you’re still unsure about his green cred, he built the first LEED Platinum home in the United States (with the design help of Ray Kappe). Enjoy…
If you’re going to office in what looks to be the greenest skyscraper in the country, you should also have a sustainable business strategy to go along with it. One Bryant Park, soon to be known as the Bank of America Tower, is the perfect place for a company that just announced a $20B initiative to support environmental lending. Designed by Cook + Fox Architects and developed by the Durst Organization, One Bryant Park is shooting for LEED Platinum certification. It’s a 2.1 million sf, 54-story, crystalline office tower located right in midtown Manhattan and is slated for completion in 2008.
ABC News recently ran an article on some of the more interesting green features of the building. Interestingly, it will only cost about 1-2% extra (of a total $1.2B) to include all the green additions, but those are expected to be paid for within a 2-4 year window as a result of saved energy expenses. That’s the business case for green building. There will be rainwater capture, floor-to-ceiling windows for natural lighting, advanced double wall technology to allow light and block heat, air cleaned of 95% of its particle matter, a floor duct air system controllable in each room or office, three state-of-the-art natural gas fuel cells to create on-site energy, building concrete made of 45% blast furnace slag for stronger construction, and daylight dimming and LED lights for reduced electric usage. The result: these green additions have the anticipated benefits of reducing energy consumption by 50%, reducing potable water consumption by 50%, reducing storm water contribution by 95%, and using about 50% recycled materials in construction. That’s a lighter footprint.
- Bank of America Announces $20 Billion Environmental Initiative – BofA announced a $20 billion initiative to support the growth of environmentally sustainable business activity to address global climate change. Bank of America’s ten-year initiative encourages development of environmentally sustainable business practices through lending, investing, philanthropy and the creation of new products and services.
- Residential Green Building Slow to Gain Momentum – The major homebuilders, who account for 80 percent of all homebuilding activity in the nation, face a unique challenge in implementing green building on a widespread scale. Many have added energy-saving features and experimented with environmentally friendly materials but have not yet been able to sign on a critical mass of buyers willing to pay more for them.
- Easy, Eco-friendly Ways to Put Those 21 Extra Hours of Evening Daylight to Good Use This Spring – Tomorrow, the entire nation will spring forward three weeks early, gaining an extra 21 hours of evening daylight. Since energy conservation is the driving force for the early time change, Lowe’s is encouraging homeowners to utilize these hours wisely with some simple, green projects that would make Mother Nature smile.
Don’t forget to spring forward tonight.
This is the K1 from kitHAUS, which is a prefab company based in Van Nuys, California. The K1 is 289 sf and costs around $59,000. kitHAUS has a series of modules that can be paired (or not) to create a small weekend retreat, backyard office or study, or gigantic residence. Plus, it can be off-grid or grid-tied with the optional solar setup, depending on your tastes.
