Golden Gate Green

san franciscoIn a series of independent studies, San Francisco has consistently earned top marks for being environmentally friendly, ranking in the top three (with Portland and Seattle), often taking the the top spot.

Being eco-conscious can be difficult to define, and depending who is conducting the study the parameters may vary. One key factor is per capita public transit ridership. New York City ranks #1, with San Francisco coming in at #2. Addiotionally San Francisco ranks very high for bike ridership with nearly 50,000 weekday commuters riding bikes. In 2017, 14 miles of bikeways were added or upgraded.

For recycling and carbon footprint, San Francisco again ranked in the top three along with Seattle and Portland. In this category San Francisco edged out the other contenders due to voter awareness, participation,and routinely voting for aggressive green programs and renewable energy programs. San Francisco diverts 70 of its waste due to mandatory recycling and composting.

Is the sustainable food category San Francisco again earned top ranking. With the farm to table movement, veganism, and grocery stores which feature and support sustainable practices, San Francisco has become known as an epicenter for healthy dining options. It is also worth noting that San Francisco residents on average consume less than half compared to the rest of the state.

With its green and open spaces, myriad hiking and biking trails and coastline, San Francisco is a great place to be green.

The Sky is the Limit

Sales Force Tower

In addition to the many green projects we work on, we like to showcase innovative green and smart structures here at home and around the world, hi-lighting the cutting edge building technologies, products and designs that are now available.

Salesforce Tower is now the tallest building in San Francisco, with an overall height of 1,070 ft. In keeping with Channel Lumber’s high standards for sustainability and green building, Salesforce tower is pre-Certified LEED platinum.

Over a decade of planning went into bringing this icon into fruition. It is part of the Transbay redevelopment plan, which will develop offices, transportation, residential and retail uses.

The top portion of the building features an electronic sculpture, “Day or Night”, created by artist Jim Campbell. The sculpture projects images and video captured around the city on the same day.

The construction of the project is a massive achievement for modern day engineering, materials, and subcontractors. Starting at the ground level, the mat slab floor, the foundation of the building, is reinforced with #18 rebar, the largest available. The concrete pour for the foundation started at midnight and ran 14 hours, until 2 pm, at a rate of 900 yards per hour. This amount of concrete could fill 1,400 trucks. The rebar weighs a total of 5 million lbs. The core walls surrounding the mat slab floor are 4 feet thick, the thickest of any San Francisco building.

The pace of construction was extremely fast requiring flawless planning and execution. Once the foundation was laid, 2 floors per week were built on a round the clock schedule.

The building features a state of the art air distribution system, and blackwater recycling system, among many green features.

The building is currently at 97% occupancy, with Salesforce.com being the primary lessee.

Smart and Green: The Manna House

Manna HouseChannel Lumber is committed to green and sustainable building. The Channel Lumber headquarters itself has many green amenities and features including a broad energy efficiency and solar generation platform.

In addition to the many green projects we work on, we like to showcase innovative green and smart structures, and the cutting edge technologies, products and design that are now available.

The Manna house in Los Angeles, designed by architect Jeremy Levine is a modern smart home that utilizes extensive sustainable systems, and recycled and non toxic materials. The flooring throughout the house is either recycled or unfinished plywood, as are the ceilings. All of the decking is composite recycled material. The kitchen and bathroom countertops were all poured in place with concrete using environmentally friendly fly ash.

The home is powered by a photovoltaic solar energy system. It also features a rain collection and grey water recycling system which are both utilized to water fruit trees and a garden. The passive cooling system is acheived by using low windows on one side of the house and high windows on the opposing side creating a natural breezeway, and a movable fan for days when there is no breeze.

Non VOC paints and stains were used, and all electrical appliances are energy star rated.

BART Berkeley Hills Tunnel

Bart car

The BART Berkeley Hills Tunnel runs between the Rockridge and Orinda stations. Construction began in 1965, with construction completed in 1967 after 465 work days. The tunnels are offset to the north of the Caldecott Tunnel, and provide a more direct alignment. The contract for construction was $31 million USD.

Channel Lumber has partnered with engineering and construction firms providing services and goods in BART construction since BART’s inception.

The Berkeley Hills tunnels are 3.1 miles longs and about 17.5 feet in diameter. There are emergency cross tunnels every 1,000 feet for evacuations. The east portal has roll down doors which close off the tunnel, or allow for ventilation in and out. The tunnel runs across the active Hayward Fault.

Construction of the tunnels involved over 27 million pounds of steel. The rate of advance between boring, blasting and excavation was 19 feet per day. The project was one of the earliest high profile tunnels to be built with Tunnel Boring Machines (TBMs) as opposed to hand mining.

The building of BART during a cycle of high inflation, led to many well documented budget and political problems. In many instances these problems led to political reform. In 1974 BART was nominated for Outstanding Civil Engineering Achievement of the American Society of Civil Engineers.

Green Giant: Bank of America Tower, Manhattan

Channel Lumber is committed to the process of Green Building, and supporting LEED certification. Today we want to showcase a cutting edge Green skyscraper and highlight the latest Green design and amenity features.

In 2009, construction of the Bank of America Tower, in Manhattan, was completed. The building earned a LEED Platinum rating, the highest awarded. The rating is based on various environmental considerations. The design earns “points” for various energy saving and environmentally beneficial features. The cost of construction was One Billion USD. It is the fourth tallest building in Manhattan.

The design teams for the tower had one directive: to demonstrate that economic and environmental principles are compatible. When Green features added to the cost of construction, only those features which would pay for themselves within 5 years were included.

There were many other areas where the tower scored well including site selection (near public transportation), building form, and energy conservation.

The towers’ sloped form has two primary benefits. First, it allows more natural light to penetrate the building. 90% of workers have floor to ceiling windows which can be fully lit with natural light. Second, the sloped form allows for the efficient capture of rainwater, which can then be used in a variety of ways.

The Bank of America tower has an onsite natural gas power plant which generates 70% of the buildings electricity consumption, and 30% peak hour consumption. This eliminates electrical transmission losses which are significant on the city’s power grid.

The power plant makes ice at night which is used to cool the building in the day. Additionally the waterless urinals save up to 8 million gallons of water annually.

Channel Lumber has an extensive list of Green Projects and clients including the Aria Resort and Casino, Veer Towers, and the Portola Valley Town Center.

Channel Lumber Custom Lumber Shop: Corbels

In architecture a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket.

Stone corbels - Channel Lumber

An example of an ornate stone corbel on a building

You see corbels throughout San Francisco, and they are very common on Victorian homes. Many corbels on homes are made of wood, and as such are prone to rot over time. The corbels often have unique shapes, and we copy the shape to replace rotten corbels, and match any remaining corbels on the building.

Profile of a corbel

Custom corbels are made according to the following steps:

  1. Wood of the proper thickness is chosen, or wood is laminated to achieve the desired thickness.
  2. The wood is run on the joiner, cleaning up and making smooth surfaces.
  3. The wood is chopped to length with a miter saw, giving two clean working ends.
  4. The wood is then run through the thickness planer bringing to the proper dimension.
  5. The outline of the old corbel is then traced onto the wood.
  6. The outline is cut with a bandsaw.
  7. The new corbel is sanded and painted as needed.

Earth Day 2018

View of Earth from SpaceEarth Day is a Global event which will be held on April 22 of this year. The campaign and focus for this years’ Earth Day is “A World Without Plastic Pollution”.

Over the past several decades, plastic pollution on our planet has grown exponentially. As a result, Earth Day is committed to fundamentally changing human attitudes and behaviors about plastics, and to sparking a drastic reduction in plastic pollution globally.

Plastic Pollution is pervasive at all levels in nature and within our infrastructure. We have all seen pictures of plastic bottles in nature, etc. but this is just the tip of the iceberg. As plastics decompose, they become smaller and smaller bits of pollution eventually so small they can not be seen and are very difficult to contain. Eventually these particles make it into our tap water system. A recent study showed that 94% of American tap water contained plastic pollutants.

The Earth Day Campaign will be an all out attempt to build a Global framework of plastic pollutant reduction with a vertical approach, from grassroots education, school system outreach, advertising, encouraging more reports in the news, and reaching out to our Global Leaders to take an aggressive stand on the issue.

You can track your own plastic pollutant footprint and learn how to make changes using the Earth Day End Plastic Pollution Kit.

For more information and to get involved please visit the Earth Day website.

Today is International Day of Forests

forestInternational Day of Forests is celebrated on 21 March each year. It was established in 2013 by the United Nations, and the week long symposium and celebration is hosted by a different country each year. The theme for this years’ International Day of Forests (IDF) is “Forests and Sustainable Cities”.

The slogan for this year’s’ celebration is “Let’s make our cities greener, happier, healthier places to live.” There is comprehensive list of topics on the IDF website, and among the primary messages are that trees contribute to a host of benefits in an urban setting. These include that forests store carbon and help to mitigate climate change. Trees can be used to cool air, thus decreasing the need for air-conditioning and power consumption. Lastly that green urban spaces contribute to more healthy active lifestyles.

It is estimated that deforestation contributes to 10-20% of climate change related problems. Each year the world loses 13 million hectares of forests, approximately the size of England.

The concept for IDF started casually at Oxford, England, when two professors agreed that the consequences of deforestation especially as it relates to climate change was being grossly underestimated. Over the next several years, with support of the United Nations, the IDF was founded and continues to be a source of education, awareness and action around protecting and developing forestry around the world.

Sustainable forestry is, and will always be, one of our driving missions at Channel Lumber.

Alaskan Yellow Cedar

sail boat - channel lumberTransformational Sailing is an organization which helps Veterans and others with stress related disorders find relaxation through sailing. Their motto reads “The Power of Healing Through Wind, Sea, and Sky”. The organization is also involved in boat building for which Channel Lumber recently donated Alaskan Yellow Cedar.

Sailing is an activity which can provide a climate for community building, safe communication, working as a team and relying on others, to name just a few of the benefits. For veterans who have become disconnected through war related trauma, Transformational Sailing offers participants a chance to recover a normal, healthy lifestyle, and relate to others with similar experiences.

The Transformational Sailing website features several videos where the participants are asked what the highlight of their day was. Gerry, a former WWII captain answers “getting the feel of the helm again. It’s good to get back on the wheel”. Jason, another Veteran, simply answers “To feel human again. To get to be just like everybody else.” The testimonials are heartfelt and powerful.  They communicate what a needed and transformational experience these sailing voyages provide.

The sailing trips are typically about three hours throughout the Bay. Newcomers often just sit and enjoy the adventure, but over time participants learn sailing skills, and have progressively hands on experiences including manning the helm.

To find out how to get involved and or make a donation please visit the Transformational Sailing Website.
