It's gonna be a bright sunshiny day

As the rains from last week (yes all week) subside, the skies are clear, fresh and clean.  As I am evaluating the performance of the photovoltaic system with California Solar Energy Company we are reviewing the estimated generation vs. actual conditions. 

The results for today: Great news.  Each system was estimated to produce 6.7 KW/H and were ahead of track at about 7.4 KW/H for the systems we reviewed at noon. 

It seems the rain potentially cleaned the panels, paired with ideal solar conditions; a lot of sunshine and mild temperatures, and they were cranking out power. 

Now on to more studies on how we can potentially optimize the generation.   Stay tuned.

Fill er up



To help enumerate the water savings associated with the features in this project, we've decided to compare it to a "standard" home.  A standard home is one designed to meet minimum code requirements.   These are estimates and will hopefully be confirmed, denied, or amplified, during the life of this study.  The water saving features include dual-flush toilets, low-flow showerheads, and native planting.

I acre foot = 325,851.427 gallons, which equates to approx 1 football field filled with 1 foot of water. 
  • It is estimated that 1.9 million gallons of water will be saved per year (5.8 acre feet). 
  • Over 55 years this = 104,500,000 gallons of water (320.7 acre feet).
  1. Lake Cahuilla has 1,500 acre feet, or 488,777,140.5 gallons of water.  The amount of water saved over a period of 55 years will fill up approximately one quarter of Lake Cahuilla. 
  2. The Desert Water Agency says that 1 acre foot of water is enough for a family of 4 to live on for a year.  Vista Dunes saves about six acre feet of water per year - enough water to supply 6 families of 4 for an entire year, or 330 families of 4 over the course of 55 years. 
  3. If Vista Dunes saves 320.7 acre feet of water over 55 years, that's enough water to fill almost three football stadiums (based on the size of Arizona State University's Sun Devil stadium which is 122 feet high)
  4. The average golf course uses 144 million gallons of water per year, or 441 acre feet.  It would take 76 years to water a golf course for one year using the water saved by Vista Dunes. 
  5. The Empire State Building is 115,284,752 cubic feet, which could hold 862,399,833 gallons of water, or 2646 acre feet.

New beginnings

In the spirit of the new decade upon us I pulled out this photo of the Vista Dunes site as it existed in the mid 1900's.  Known as Happy Dunes Trailer Park, it was the first establishment in La Quinta, California.  You can just feel that fresh desert air with the snow-capped mountains in the distance and the open space around the site.  The road (now Miles Avenue) leads both newcomer and wary traveler the same, into the community. An open invitation to establish a life in any way you choose.   The subsistence of this site has now transpired as much an inspiration and opportunity for a new life as it was in this first photo.

Telling a Thousand Words


We have our first families involved.  What an enormous volume of information they are willing to give.  Surprisingly none of the participants are hesitant to talk about any aspects of their daily life and habits, and definitely not hesitant to relinquish opinions on materials, water temperature and unit design.  It's like the cliche, A picture tells a thousand words.  A tank-less water heater, an inverter, a shade trellis, and a snowman in the desert- how does it all play out?


Ray is a single mom with 2 daughters.  She has lived in Vista Dunes for over a year, with the last 9 months in a 2-bedroom rather than a 3 bedroom, where she previously lived.  Before moving to Vista Dunes, she lived with her mother.  She does not own a car, she does not work outside the home, and she walks or takes the bus everywhere she goes.  Her electricity bill is currently $11 per month, while her mother's whom is local to her, just paid $220.  She appreciates the difference.  According to Ray, her thermostat is set to 79 degrees all day and night in the summer, but the concrete floors help.  "It's better than going swimming in the pool.  If you need to cool off (in the summer), just lay on the concrete floor".  She told me how she grows her own vegetables outside in a baby pool in the spring and summer. 

Dr. Turf is likely to be the most difficult to improve upon, because he's already in tune with what is going on in his home.  He lives alone in a 3-bedroom, and used 748 gallons of water in the month of November.  He's budgeted 7480 to remain in the Excellent  Service Charge range.  He owns a vehicle, travels out of Vista Dunes for work with varying mileage, and uses the bus to travel some.

Jane has lives in a 2-bedroom alone, as his youngest daughter just moved out.  He does not work because he became disabled on the job several years ago.  He chooses to drive his vehicle everywhere noting that walking or the bus are too hard on his back.  Jane enjoys comparing habits, particularly showering habits of men vs. women.  His electrical consumption has gone up since his daughter moved out a month ago, but he checks the solar inverter every day to make sure it is generating.  My favorite line; "the (warm) water in the kitchen sink travels to Paris, then to Mexico, before it comes out in the sink".

Dashboard Envy




I have sent out the Resident Questionnaires, have begun planning my first trip later this week, have reviewed input from numerous parties, and I have now reached the part of this study where I covet more.  Already.  

I want a Dashboard for this project.  Not those where I can see how much gas is not left in my vehicle or the average mpg we are all used to looking at, a sleek, and beautiful Building Dashboard.  One that shows me on a screen exact numbers on resource consumption of the house, stores it and displays it in endless possibilities. 

For now, I will fine-tune my typed questions and personal meetings, and I realize that some things can not be studied from a computer.  To satisfy my impulse, and will get a TED for my house and gift one to a family member for a little friendly competition.

A meeting of the Minds


I recently traveled down the unspeakable 5 freeway to San Diego to meet up with a colleague and friend I met through the Vista Dunes.  Rather than The Fountainhead version of design, Vista Dunes utilized a bit of collaboration through Design Architect, Studio E Architects.  As Eric Naslund and I caught up on recent projects, I asked if there was anything he would like to specifically evaluate in this study.   I could almost say the response simultaneously as he noted "Yes, do they use the vent towers"?  We did not get any "credit" for those in LEED-H or in California T-24, but the idea is that they help the natural ventilation and add more daylight to the living space in the units.  More to come on that topic.

hand-off

As the residents moved in and the punch-lists were closed up on the project, National Community Renaissance or CORE began managing the site.  Check out the developer's project site information and online tour.

WHAT am I doing?

Hey, my forte is to design buildings or homes and not blogs, and I recognize that, but I'm also looking for ways to impart experiences on this project with others.   So now, join me as I tread lightly on new territory and add comments, criticism, supplemental information, or suggestions on what you'd like to see. 

Here is information on the Home Depot Foundation Award Announcement and more information on the project.

One Fine Day

On Friday, November 13, 2009, at the Greenbuild Closing Plenary in Phoenix Arizona, the Vista Dunes Courtyard Homes was announced as the winner of The Home Depot Foundation Award of Excellence receipient.  This blog will follow the year-long study in evaluating the successes and failures (maybe there will be 1....?  or 2?) of this project in hopes to provide public information for projects of the future. Any and all feedback is welcome.
