rinaldo vesileza pictureClean, fresh water is an essential resource that has been dwindling at an alarming rate over the past few years. The importance of conserving and recycling water will be the topic for this event. In particular, examples of sound practices in architectural design will be described that have implications on Silicon Valley and all of California in this severe "drought state" and state of mind. Please come join us for this fascinating talk with real world examples of what cities and businesses can do and are doing with proper planning, design, and communication. 



Industrialized Fog Water Harvesting PDF Print E-mail
Written by Tatiana Estevez Carlucci   

tatiana linked in picOur November 19th meeting will provide insite into an industrialized methodology and technology for passive catchment and storage of fog as a new water source for residential and industrial use. As rain water is considered vertical precipitation harvesting, fog water is considered horizontal precipitation harvesting and can collect up to three times more water than rain without disrupting other ecosystems in areas where the requirements for fog water harvesting are met. Tatiana Estevez Carlucci will take us on a journey to explore a fascinating new technology which is being realized through her company, Permalution. Join us for this exciting look at a technology that can provide a new water source and help address some drought issues.

California Clean Initiative PDF Print E-mail

Cheriel Jensent picThe statewide initiative we are planning will prohibit the most common mind-damaging, cancer -causing, birth defect-causing chemicals in our bodies, food, water, soil, air, and creatures of the environment.

It will prohibit aircraft and truck mounted pesticide foggings and the significant off-site drift they cause. Remember the medfly Malathion aircraft spraying in this valley in 1980-82? Remember the Monterey-Santa Cruz plastic-bead-encased pesticide from aircraft fogging using the Light Brown Apple Moth "emergency" excuse?  And remember the last 10 years of repeated summer pesticide fogging in Santa Clara County claiming a West Nile emergency? When we discovered that the first pesticide they used Pyrenone 25-5 contained cancer-causing piperonyl butoxide they switched to the even more toxic Zenivex E4.  The Department of Agriculture is planning on endless toxic dousing for whatever new emergency they concoct.  They have finalized their so-called Environmental Impact Report.  So we must do an initiative now to stop this repeated poisoning.

Opportunities for Sustainability in Commercial Buildings PDF Print E-mail
Written by Tony Green   

TonyGreenCommercial buildings include buildings greater than 1,000 square feet which devote more than half of their floor space to activities which are neither residential, manufacturing, industrial, nor agricultural.


This includes stores, office buildings, schools, churches, gymnasiums, libraries, museums, hospitals, clinics, warehouses, and malls. The design, construction, operation of commercial buildings impact natural resources, environmental quality, worker productivity, and community well-being.


Approximately 9 percent of the total water use is consumed by commercial and institutional facilities in the United States and up to 17% of publicly-supplied water use. Three applications: sanitary (e.g., toilets, sinks), landscaping, and heating/cooling account for 88% of commercial building water use.
