Please Join Us for the First Collaborative Informational Session

We issued the invitations today to our first of six Collaborative Informational Sessions.  The first event is on Saturday, October 24 from 12:30 pm to 4:20 pm.

To register for the event, you must go to the event registration site.


We are hosting these informational events as part of our ‘showcase’ of innovative building materials and innovative construction practices.  We are collaborating with the Santa Clara Valley chapter of the AIA, the USGBC Northern California Silicon Valley Branch, and Build It Green‘s South Bay Guild.

Our invitation reads as follows: 

You are invited to the first of six collaborative information sessions to see the construction of a zero net energy, zero carbon house being built that is applying for LEED-H Platinum certification.
The benefit of seeing this house as it is being built is that you will see how green materials are used during the construction process. Many of these materials will be ‘covered’ when the house is completed so this is an opportunity to understand what is behind the walls. Attending the informational sessions allows you to see how we are using innovative building materials and innovative construction practices throughout the construction process.
During the informational session, you will be able to ask questions regarding the green building materials to better understand how these innovative building materials affect the cost of construction, the skills required to use these materials, and how using these materials affects the construction timeline.
The project involves constructing a full lower level (basement) under an Eichler home, built in 1969, while renovating the main floor. The green features of the house include:

  • Roof made with SIPs (Structural Insulated Panels) by Insulspan (12¼ inch – R47)
  • Geothermal heat exchange with 3,000 ft. ground loop in 25 vertical concrete piers
  • Floor constructed with 50 hollow core concrete panels, manufactured in Los Angeles (Irwindale) that were placed in 4 hours
  • Concrete mix that includes high slag content (70% in the mat slab and 50% in the shotcrete foundation retaining walls)
  • Water-to-water heat exchange with radiant heating throughout the house
  • 48 roof-mounted photovoltaic solar panels, with two inverters, to be a net generator of electricity
  • 3,700 gallon cistern, to harvest 100% of the rainwater, that will be used to irrigate drought-tolerant native California plant species
  • The original design of the house included generous roof overhangs that limit direct sunlight, reducing solar gain in the summer. This passive design has been enhanced with the use of 1.5 million lbs of insulated thermal mass (concrete) in the house that will slow heating from solar gain and slow night time cooling.
    Overall, the house performance exceeds (is better than) the Title 24 standard design by 72.9%, which is one of the highest performing single family dwellings in the State of California.
    Given this is an active construction site, you will have to register in advance to attend the session and, when entering the site, sign a waiver acknowledging the inherent risks of an active construction site.
