Thanks to Fire Resistant Architecture, UC Santa Cruz – Big Creek Reserve Unharmed by Dolan Fire

We were relieved to learn that the Research and housing that we recently completed at the UCSC Big Creek Reserve escaped the Dolan Fire undamaged thanks to fire resistant architecture and the work of Reserve managers and UC staff alongside CDF to face the emergency. It is also the result of good planning that included WUI (Wildland Urban Interface) standards for fire-resistant construction, water storage and site preparedness. ⁠

Resilience in the face of climate change, and the study of how the coastal ecosystem is responding is a big part of the mission of The Reserve. The Conservation Biologists who study and work at Big Creek know the fire cycle from academic and up-close-and-personal perspectives. We appreciate and support their work and are glad that advanced planning, architecture, and design helped in some way.⁠

Working with the Conservation Biology Department, Levy Art + Architecture developed fire-resistant designs for a living classroom, scientific research housing and staff housing on the 7000 acre Natural Reserve site. In addition to developing an appropriate architectural language, we have coordinated a project team to create a complete, standalone facility that is self-powering, and environmentally neutral in terms of water supply and wastewater disposal. The level of difficulty is increased by the close proximity to the pristine Big Creek and its riparian zone. Budget constraints were extreme as we were asked to develop two, separate sites, that each required complete infrastructure for water, power, wastewater, road and fire access, as well as protection for sensitive environments and species. We have worked through a rigorous UC process and created an exemplary architectural response.

This project aims to be the first residence in San Francisco that is completely self-powering and carbon neutral. The architecture has been developed in conjunction with the mechanical systems and landscape design, each influencing the other to arrive at an integrated solution. Working from the historic facade, the design preserves the traditional formal parlors transitioning to an open plan at the central stairwell which defines the distinction between eras. The new floor plates act as passive solar collectors and radiant tubing redistributes collected warmth to the original, North facing portions of the house. Careful consideration has been given to the envelope design in order to reduce the overall space conditioning needs, retrofitting the old and maximizing insulation in the new.

An Edwardian Divorces PG&E

As the managing director of San Jose–based SunPower corporation, William Kelly unabashedly geeks out about solar panels. But when he set about expanding his family’s 1904 Noe Valley Edwardian, he took things a step further, getting “off the pipe”— eliminating the need for natural gas. Instead, a radiant system of water-filled tubing beneath the floorboards provides heat, and cooking is done on an induction stovetop. San Francisco firm Levy Art and Architecture expanded the home to 2,424 square feet, moving living areas to the south-facing rear of the house to harness the sunlight; a skylight over the glass-encased three-story staircase lets natural light reach from rooftop to basement. Meanwhile, SunPower’s photovoltaic solar panel system channels 7.6 kilowatts of electricity—enough to power the home and the family’s two cars. J.F.

Zero Energy House hits Asia

Blog FuturArc JanFeb2013cover

Zero Energy House was published in FuturARC (an Asian Green Architecture magazine) early in 2013, in an article written by Jalel Sager.  The article explores the California codes, the most stringent in the US (probably the world). Here Jalel finds several developments that go further than most; their owners speak of sharing their abode with the planet. The battle between the personal and the political is fought on the fringes of mainstream Green.

Fly Ash in Concrete

R FlyAsh NeonTumbler

There has been a lot of discussion recently about fly ash in concrete as there are concerns about heavy metals in this by-product of coal fired power production.

 “Replacing Portland cement is a high priority for all of us…” Russell Perry, Smith Group

“The Environmental Building News (Alex Wilson) continues to support the use of coal fly ash in building materials as long as:

  1. the use of fly ash reduces green house gas emissions elsewhere in the materials stream and
  2. the fly ash is chemically and physically locked up so that the risk of leaching is kept acceptably low.

A 2008 study by researchers at The Ohio State University found that fly ash concrete exposed to heat through steam curing retained 99% of its mercury content and showed final emissions similar to thoseof common soil.

A follow up study at Ohio State in 2009 that looked at both gas emissions and liquid leaching showed that the amount of mercury emitted from fly ash concrete was independent of the amount of mercury in the cement.

In California and much of the Western United States, the primary cement substitute in concrete is slag. Bode concrete, for example, advertises a “green” mix that is 30% slag and 15% flay ash, in place of 45% of Portland Cement.

Slag is byproduct of the metal smelting process. Common components of slag include the oxides of silicon, aluminum, and magnesium, as well as sulfur, which is always present. Slag also contains phosphorous, calcium, ash, remnants of flux materials such as limestone, and remainders of chemical reactions between the metal and the furnace lining. Slag cement has actually been used in concrete projects in the United States for over a century. The earliest use of slag cement was documented in 1774, when it was combined with slaked lime and used as a mortar. Slag cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slag-lime cement.

Eco-Justice

R EcoJ EBBoatScrap

Supporters of eco-justice attack the historic lack of regard for non-human parts of the environment. They encourage respect for living things as well as the various parts of the biosphere.

Advocates of eco-justice reject the idea that the worth of a thing is its value to human beings. They argue that other parts of nature have value entirely independent of their usefulness to humanity.

Natural systems depend on diversity, and adaptation to provide resilience in a dynamic environment

Human beings, as part of this system, depend upon bio-diversity as a reservoir of potential that allows for the entire system to respond to changing conditions.

Given our growing ability to comprehend the profound nature of these inter-relationships, human beings have an ethical responsibility to protect these processes.

Wasteful practices and their hazardous byproducts have typically impacted the less fortunate (or less vocal), be they human, animal or plant, giving rise to the idea of Eco-Justice

There are a variety of Guidelines and programs aimed at reducing our environmental footprint.  The more modest attempt to be “less bad.” The most progressive propose to create a healing framework.

  • Reducing Impacts
  • Increasing efficiency
  • Achieving Net Zero Energy Use
  • Achieving Net Zero Water Use
  • Building Regenerative Systems
