LEED-H Silver, Energy Star, Earth Advantage – Dolph Creek Townhomes

Dolph_creek

In Portland, Oregon, there’s a sustainable development called The Headwaters at Tryon Creek, which is a 2.88 acre, master-planned, mixed-income community that prioritizes sustainable building practices, energy + water conservation, wildlife habit restoration, and stormwater management.  One portion of the development includes the Dolph Creek Townhomes, which are 14 for sale, attached townhouses that are LEED Silver, Energy Star, and Earth Advantage certified.  Quite the list of certifications!  These luxury townhouses vary in size from 1,585 – 1,695 square feet, and in price from $369,950 – $379,950…purchasers qualify for the State Residential Energy Tax Credit. 

In addition to saving up to 45% on annual energy costs, here are some of the green features:  solar panels with 80 gallon storage tank, energy efficient windows, green label carpet, formaldehyde free cabinetry and wood products, heat recovery ventilators, on-demand gas and solar water heating, polyfoam insulation, exhaust fans in all the garages, drip irrigation system, and low-flow toilets, showers, and water faucets.  Of course, the floors will be bamboo (hopefully not the Chinese import variety) and the patio will have ipe hardwood decking.  From what I’ve seen, this looks like quite the community.

The Energy Star-rated Owens Corning (NYSE: OC) world headquarters building in Toledo, Ohio, has added another badge of honor with Silver LEED-EB certification.  Designed by Cesar Pelli (listed by the AIA as one of the 10 Most Influential American Architects) and built in 1996, Pelli spoke approvingly of the certification, "I am pleased this facility provided the solid foundation needed to earn the recognition that the LEED Existing Building certification provides."  For a couple other examples of LEED-EB buildings, feel free to click over to read about Adobe + Union Bank of California Center.  Owens Corning also runs The Pink Panther Energy Blog, which informs customers on insulation + energy conservation best practices. 

Green Features:
Here are just a few of the green features mentioned in the certification: under-floor ventilation for energy-efficient air delivery and specific control of thermal comfort; low maintenance, indigenous landscaping; easterly facing building allowing for natural lighting control via adjustable shading; and reusable, removable, non-adhesive carpet squares throughout almost the entire building.  See also CO + PRNewswire

Skyscraper Sunday: Arterra – The LEED-Certified San Francisco Treat

Arterra

Arterra is an urban living, high-rise community in Mission Bay that will have a mixture of flats and townhomes of various sizes.  Arterra has three buildings: "Sky," a 16-level tower, "City," a 9-level building, and "Park," a 6-level building with 2-story homes.  Go to the Arterra website and you can watch a video that shows you the views from each building.  Because Arterra is a high-end lifestyle community, you will have benefits such as 24-hour concierge, state-of-the-art fitness center, community lounge, rooftop sun deck with lounge and barbecue, etc.  But, another feature of Arterra is that it will be the first LEED-Certified Green high-rise community in San Francisco. 

Green Features:
Arterra is going after LEED certification, so here are some of the current green amenities being planned:  formaldehyde-free cabinets (Studio Becker); low-emitting paint and carpets; high-efficiency water heating boiler; Kohler dual-flush toilets and other water-saving features; low-E, energy-efficient, insulated windows; Energy Star home appliances and gas ranges; bamboo for all standard kitchen floors; cork flooring at all elevator levels; recycled glass floors and FSC-Certified wood walls in entry-level lobby; bicycle storage in the parking garage; and recycled content panels for the exterior facade.  Arterra is being developed by Intracorp Companies

Green Building: Finding True South to Optimize Orientation

Petrangelo_001_1

You may have already heard that House & Garden Magazine took a green approach in its latest installment, the February issue I believe.  One article talks about an interview with William McDonough, in which he mentions the orientation of a home.  Earlier, I blogged about Global Green USA’s Top 20 list of low- or no-cost green building strategies and orientation was #1.  Regarding orientation, the rule is to "orient a building to maximize natural daylighting."  As part of the orientation process, one needs to find a building’s true south and build it in such a way, to maximize sun exposure/non-exposure, and thereby, optimize energy-efficiency (i.e., use the sun instead of artificial lighting, use the sun’s warmth instead of heating, use the shade’s cool instead of air conditioning, etc.). 

McDonough pointed out that many architects and builders don’t know how to find true south.  If a compass is used, the compass indicates south, which can differ from true south by more than 15 degrees.  Remember, orienting a home is about orienting the home to sun exposure, not magnetic south.  To find true south, one needs two things:  (1) to know your geography’s solar noon, and (2) to use the sun to draw perfect north/south line exactly at solar noon.  Solar noon is the time when the sun hits the highest point in the sky and can be found using the following Sunrise/Sunset Calculator.  Once the solar noon is figured out, take a line with a weight attached to it, hold it up in the air at solar noon, and the shadow line will reveal the proper north/south orientation of a home.  That line will point to true south and will help you build the home properly, assuming you have some latitude in deciding the orientation of the home.

SCIPs + Green Sandwich Technologies

[Runtime = 28:46 min.]  You probably heard about Green Sandwich Technologies (GST) earlier this year when William (Bill) McDonough, FAIA, announced that he’d be on the company’s advisory board.  Structural Concrete Insulating Panel (SCIP) technology, also known as Welded Wire Sandwich Panel, has been mentioned in most popular magazines and has the unique achievement of meeting the Cradle to Cradle design protocol.  This video shows Green Sandwich panels in action.

GST panels have 7 main advantages:  (1) strength – wind load capacity of 200 mph+ and earthquake tolerance of 8.0+; panels resist pests, mold, and vermin; have the highest fire rating in the industry and are water resistant; (2) speed – allow buildings to be erected in 1/2 the time of conventional construction; (3) flexibility – panels can be used for residential, commercial, and industrial uses for floors, walls, roofs, ceilings, pools, and fences; (4) superior sound insulation – they transfer 66% less noise than wood and steel frame walls; (5) superior temperature performance – delivers R-40 performance, good for both hot and cold climates; homeowners can save up to 60% on home energy costs; (6) environmental friendliness – panels contain about 60% recycled/reclaimed materials by volume (40% by weight) + all waste is 100% recyclable; and (7) affordable – builders recognize value in cost savings such as 50% less construction time, 4-12% labor savings, 4-12% material savings, equipment savings, loan carrying cost savings, and energy savings up to 60%.  Click here to see a list of building applications.

Top 20 No- or Low-Cost Green Building Strategies

Global_green_no_winner

One aspect of green building that gets overlooked is financial independence.  For instance, a commercial business may make an investment in solar power (provided incentives and rebates make it economically feasible) to stabilize electricity bills and hedge against future electricity cost increases.  Another example is the principle of waste reduction in green building.  Did you know that building green often costs the same or just a little bit more than standard code-built homes?  And did you know that even then, green homes will require less money going forward than standard code-built homes?  To that end, here are some affordable green building strategies (click this link to read more about each strategy):  Global Green’s 20 Affordable Green Building Strategies:

  1. Orient the Building to Maximize Natural Daylighting
  2. Place Windows to Provide Good Natural Ventilation
  3. Select a Light-colored Cool Roof
  4. Provide overhangs on South-facing Windows (be careful of your hemisphere!)
  5. Install Whole-House Fans or Ceiling Fans
  6. Eliminate Air Conditioning
  7. Provide Combined-Hydronic Heating
  8. Install Fluorescent Lights with Electronic Ballasts
  9. Install High R-value Insulation
  10. Select Energy Star Appliances
  11. Design Water-efficient Landscapes
  12. Install Water-efficient Toilets + Fixtures
  13. Use Permeable Paving Materials
  14. Use 30-50% Flyash in Concrete
  15. Use Engineered Wood for Headers, Joists, and Sheathing
  16. Use Recycled-content Insulation, Drywall, and Carpet
  17. Use Low- or No-VOC Paint
  18. Use Formaldehyde-free or Fully Sealed Materials for Cabinets + Counters
  19. Vent Rangehood to the Outside
  20. Install Carbon Monoxide Detector

[Key: Energy, Water, Materials, Indoor Air Quality]  Now, some of these may only work for new construction or for renovation, etc., but this is a good starting point for going green, in an affordable way.  Keep in mind the geographic constraints–this isn’t an exhaustive list for every location in the world.  Different locations present unique circumstances and opportunities can vary greatly.  Via Global Green.
