Green Economics: City of Phoenix Saving $600k/year Due to Energy-Efficiency Program

Cfls If you’re new to CFLs, feel free to check out the Department of Energy’s information page on them.  When compared to incandescents, CFLs last longer, use less energy, and emit less heat.  While you need to pick the right one depending on your lighting idiosyncrasies and bulbs need to be disposed of at a hazardous waste center (see your packaging), groups like One Billion Bulbs are trying to get the word out on the benefits of CFLs.  It’s hard to calculate, but when energy is saved, the grid is called upon less and that’s a tangible benefit to your bill and your city.  Cities that keep using more energy end up debating with large companies like TXU about the pragmatics of building 11 more coal plants to meet out-of-control demand for cheap energy.  There are alternatives…

There’s an economic case for CFLs.  The City of Phoenix is saving about $600,000 a year after replacing traditional lighting with CFLs.  Mayor Phil Gordon said the city has replaced about 95% of the city’s lights with energy-efficient alternatives (as part of a $1.2 million one-time investment) and is starting to see the rewards.  At $600,000 in savings per year, that’s a 2 year payback on your investment.  This is smart business. 

Bioclimatic Design, Menara Mesiniaga + Ken Yeang (S2)

Iaa0291_1

I’ve had people ask me why I haven’t mentioned the Menara Mesiniaga, designed by architect Ken Yeang, in Subang Jaya Selangor, Malaysia.  Well…the building was modern + famous when it was finished in the ’90s, and it’s still modern + famous.  I don’t really know if I can do any justice trying to describe the structure, but I’ll direct you to some more detailed information on the building, in case you’re interested in studying bioclimatic skyscraper design and the like.  The Menara Mesiniaga, often referred to as the IBM building, is owned by Mesiniaga, a Malaysian public company in the IT sector that is somehow connected to IBM.  The 15 floor, 207 foot, intelligent building was finished in 1992, and interestingly, property values of the land around the building have flourished. 

Iaa0296 Excluding the costs of land acquisition, Menara Mesiniaga was constructed at a cost of roughly $8.9 M (USD).  The building design reduces long-term maintenance costs and lowers energy use.  On the north + south facades, curtain wall glazing minimizes solar gain.  On the east + west facades, aluminum fins and louvers provide sun shading.  All the office floor terraces have sliding doors that allow the occupants to control natural ventilation.  The trussed steel + aluminum sunroof also incorporates solar panels that power the building.  Some other features include the skycourt, vertical landscaping, and naturally ventilated core.  The Menara Mesiniaga is the epitome of building design that reflects climate characteristics specific to the location of the building.

A Simple, Effective PowerCost Monitor

Powercost-monitor-blue-line-innovations

When I lived in Japan, I was always feeling the pinch of electricity bills.  It wasn't because of over-consumption.  Things were just plain expensive.  And luckily, the electricity meter was always near the front door, so I got in the habit of opening the door to check the spin rate on the meter.  After looking at the meter, I'd walk around and unplug things that weren't in use.  Here in the U.S., though, there's no easy access to the meter, especially in the traditional single-family home.  Which is why something like the PowerCost Monitor could come in handy.

Central Oregon's First LEED-H Certified Residential Project: Newport District Modern House Project by Abacus GC

Newport_rendering

Have you ever been to Bend, Oregon?  Bend is smack dab in the middle of the state, it’s Central Oregon, and it’s beautiful.  Central Oregon is not to be confused with the rainy, western part of the state.  Bend is in close proximity to some of the best golfing, hiking, camping, rock climbing, and skiing locations in the world, which is why lots of Californians either relocate or have a vacation home in the area.  And real estate isn’t cheap, either (speaking from a Texas frame of mind).  But in Bend, you have an innovative, forward-thinking real estate company, Abacus GC, that has just received the first LEED-H (LEED for Homes) certification in Central Oregon for its Newport District Modern House Project.  It’s also Earth Advantage certified and will save about 54% more in energy consumption than a standard code-built home. 

This project (corner of NW 12th Street + Newport Avenue) includes 5 green, modern, luxurious homes, scheduled for completion in December 2006.  Each lot is 3,000 square feet, and each home is 2,000 square feet (prices starting at roughly $850k).  Here are some of the green features:  cool metal roof that reflects UV radiation and keeps the house cool in the summer; green roof trellises; xeriscaped lawns with drought tolerant and local plants (require less water and maintenance); Sierra Pacific windows made from timber that meets the Sustainable Forestry Initiative requirements; grid-tied solar energy system (2 kilowatt) from photovoltaic panels that run backwards; extensive use of FSC-certified lumber; blown in formaldehyde-free insulation (exterior walls, R-23; attic, R-50!) for energy-efficiency, sound control, and improved indoor air quality; lightweight all-aluminum garage doors that are maintenance free and recyclable; hydronic radiant floor heating systems powered by a 96% energy-efficient boiler; tons of strategically placed windows to optimize natural light and shade; locally harvested Madrone wood for the stairs and kitchen counter tops; Caroma dual-flush toilets that save up to 80% of annual water usage; 80% energy-efficient Ribbon fireplace by Spark Modern Fires (with the enclosure made of Eco-Terr recycled tiles); and Green Seal-certified, zero-VOC YOLO Colorhouse primer and paints.  These are just some of the many green features of the five homes in the Newport District Modern House Project. 

In addition to the green features, these homes are stylish:  top of the line hardware (Kohler, Grohe, Blum, Sub-Zero, etc.), 9-foot ceilings, Category-5 Ethernet cable installed, etc.  We’re are talking about luxury everything, in an extreme, environmentally-friendly orchestration.  The Newport District Modern House Project is everything that Jetson Green espouses:  Modern + Green + Healthy Living.  But specifically, these homes help an owner achieve water and energy independence, which is valuable in a world where energy prices will continue to rise and water will continue to become more scarce.  I really like the trajectory of this company and the projects they have in the pipeline–I’m sure this won’t be the last abacus GC project on Jetson Green.

Miami Design District's New Green Tower – COR (S2)

Cor_skyline

OPPENheim Architecture + Design just received unanimous approval for a $40 million, 25 story, 380 foot tall, multi-use green tower for Miami’s Design District (4025 NE 2nd Ave., Miami, FL  33137).  It’s called COR and construction will start July 2007 + complete in 2009.  COR will have 113 condominium units, 20,100 square feet of office space, and 5,400 square feet of retail space (includes cafe + furniture store).  Chad Oppenheim designed COR with the assistance of energy consultant Buro Happold + engineer Ysrael Seinuk.  As you can see by looking closely at the pictures, the 10 inch, energy-efficient exoskeleton incorporates wind turbines near the top and provides numerous environmental benefits (thermal mass for insulation, shading, enclosure for terraces).  In addition to wind turbines, the tower will use also photovoltaic panels and solar hot water generation. 

The funky, modern building design is expected to attract creative, design-oriented businesses and trendy, eclectic professionals.  Restaurants and retailers will occupy the ground floor, in an attempt to capture the urban energy of the building.  Of course, the interior will benefit from a mixture of natural sun and shading and design plans call for a high-tech building infrastructure.  Residences will range in size from studio to two-story penthouse units, which range in price from $400,000 to $1 million.  We’re talking about Energy Star appliances, recycled glass tile flooring, bamboo lined hallways, etc.  Residents will have access to the pool and fitness facility as well.  So far, so good I say.  Via Archiseek + Multi-Housing News.

  UPDATE:  I was hearing from various sources that this project wouldn’t happen.  Now, there’s an interview with Chad Oppenheim about the COR Tower.  This is legit and this is pretty cool. 

LEED-H Prototype Heather's Home: Modern, Green + Affordable

Apr_10_green_building_fort_worth_1_1 DFW builder Don Ferrier‘s daughter wanted an affordable, green home, so they retained the best, local green architect, Gary Olp of GGOArchitects, to get the job done.  The result is Heather’s Home, which has its own website at www.heathershome.info.  What’s interesting about this home is that it’s economically pragmatic, but it looks goods–it’s proof that a modern, green home can be relatively affordable.  We’re talking about a 2,038 square-foot home in the price range of about $117 per square foot ($230,000).  After getting the home design, she had to wait two months due to materials shortages, but the home took four months to build after that.  The monthly home heating and cooling bill averages $20-30 month.  That’s amazing, especially in Texas. 

Green Features:
There’s a rainwater collection system connected to a 3,000-gallon holding tank, which is used for irrigation and toilet water.  Toilets are low flush, of course.  She landscaped with drought-tolerant, native Texas plants, to conserve water.  She didn’t install a full blown solar system (costs about $30,000), but she did install enough solar panels to power the tankless water heater (also saves water).  The home design called for Structural Insulated Panels (SIP) to create a more energy-efficient, tight building envelope.  For heating and AC, the builder installed a Daikin HVAC system that runs at 20 SEER.  The HVAC system price tag was $5,500, which is cheaper than a geothermal heat pump and about 90% as efficient.  Of course, low-VOC paints and stains were used throughout.  Lights and appliances are energy star. 

The stairs are bamboo and some of the floors are stained concrete.  The kitchen island surface is a grenadine Formica (Green Guard certified) and the cabinets were created from regionally produced ash, treated with a low VOC stain.  You’ll notice the 33 glass block windows on the northerly wall, which invite natural lighting without diminishing interior privacy.  There’s a solar tube in the closet for natural lighting.  In the rooms with carpet, it is PET (polyethylene terephthalate) carpet, which is created from reclaimed polyester resins of two-liter soda bottles and and other plastic containers.  Some of the other carpet is InterFLOR modular carpet, made from corn husks.  The list of green features goes on and on!  You can go to this link to find the source of all the products used in this home.
