100k House, Trifecta of Modern, Green, Affordable

100khouseroof

Overnight, Postgreen announced its first development project in the Kensington neighborhood of Philadelphia.  It will be a small project with two small, two-bedroom homes that will be modern, green, and affordable, a powerful trifecta of aspirations.  Generally speaking, the homes will be designed by Interface Studio Architects and will be loftstyle with 2 bedrooms, 1 bathroom, and enough green amenities to qualify for about a LEED Silver certification.

Interestingly, Postgreen is also conducting a case study to try to build one of the homes for only $100K.  The purpose would be to prove that modern, green homes can be affordably built today.  They’ve started a blog, the 100k House, to document the entire process from planning to construction to sale.  If you have experience in this endeavor, and I’m sure you do or you wouldn’t be reading Jetson Green, Postgreen is looking for feedback for every step of the process, which you can do by visiting the 100k House blog.  More here.

ASAP House, Northeastern Net Zero Energy Home

ASAP House

This is the ASAP House, a House About Saving A Planet designed by Laszlo Kiss.  Like many green designs generated these days, this home will be a net zero energy home — it will produce as much energy as it uses over a certain period of time.  To do that, the home will have good insulation, Energy Star lighting fixtures, a 10 kW photovoltaic array, and a geothermal heating and cooling system.  Currently, a prototype ASAP House is being built for Sag Harbor, New York.  Just last month, the factory was moving along well on three modules that will end up completing the home. 

The ASAP house will cost roughly $250-265 psf, depending on site conditions, and is being designed with LEED certification in the works.  It is anticipated that the finished home will be about 2,500 sf, with 4 bedrooms, and 2.5 bathrooms.  It’ll be fun to follow the blog progress and see the finished product.  At that point, we’ll officially have one more prefab contender, and more particularly, one that can service the Northeast!

House of Tomorrow, Zero Energy Green Prefab

House of Tomorrow

This green prefab, sponsored by French architecture magazine Architectures à Vivre, was on display last weekend at the Batimat Show in Paris.  I think it’s called La Maison de Demain, which I also think is French for House of Tomorrow.  We’ll go with that as the name for now.  Their website is in French, so if anything, you can glean certain design elements from studying the images.  Some of the below information is from Google’s translation, so I hope it’s accurate. 

The home is built with three prefabricated modules and meant to show that green design can be affordable and attractive.  An important aspect of the house is the open area in the middle, which could be used as a covered patio to extend the footprint of the home into the natural environment.  Everything about the home is green, too, as far as I can tell: FSC-certified wood and siding, green label paints, low-VOC recycled carpet tiles, LED lighting, low-flow toilet, reinforced insulation, and photovoltaic panels.  You’ll also notice the living roof that provides numerous efficiency benefits (and seems to get water from the slanted roof).  In the end, the compact, modern home is very efficient.  Matter of fact, it’s nearly net zero energy consumption once the solar panels are live.  Nice.

[Video] Greening the Office, 7 World Trade Center

This is a quality video by Wall Street Journal’s Dana Mattioli featuring Andrew Shapiro, founder and CEO of GreenOrder.  GreenOrder is a sustainable marketing and strategy firm that’s been called the "Green McKinsey" on occasion.  Shapiro takes Mattioli through 7 World Trade Center, explaining the building’s several green aspects, including the rainwater reclamation system, floor-to-ceiling windows, design for natural lighting, and white roof.  You’ll notice also the layout of employees, which is a little more collaborative and fluid.  Experts laud these open layouts as a way to do more with less space, and thereby, save materials.  I’m still unsure as to whether tighter quarters can be more effective, especially with the extra noise and commotion — I definitely think it depends on the job type.  It probably reduces internet usage, though.

Half-Moon Outfitters Takes Platinum in Green Rehab

Halfmoon

It’s nice to hear about companies that stretch just to get the LEED Platinum certification, especially when it’s easier to go ‘certified’ and brandish that certification like it’s a shiny, new, plug-in hybrid.  Half-Moon Outfitters received the Platinum certification in the middle of the summer for their 9,600 sf distribution center in North Charleston, South Carolina.  They went for Platinum under the LEED-NC 2.2 system, and more importantly, they didn’t skimp in the energy and atmosphere category, opting instead to rack up ten points.  The distribution center was formerly an old Piggly Wiggly store, but it’s been through what could be the greenest renovation in the country.  It’s now a super green, corporate office and distribution center. 

Here’s what they did:  First, they installed two 1550 gallon storage tanks, which combined with the water efficient fixtures and native landscaping, helped them use about 78% less domestic potable water than a conventional building.  Second, they added insulation throughout the building and installed both a 4,900-watt photovoltaic system and 19 SEER efficient Lennox heat pump system.  Third, they switched to energy-efficient fluorescent lamps and found ways to benefit from the building’s east-west orientation (passive and active solar strategies).  Nice work!
