  • For organizations like Green Roofs for Healthy Cities, early advocacy literally required translating data from German – the vast majority of studies on the benefits of green roofs at the times were in German
  • Main purposes: to decrease energy costs, especially in warmer environments, to alleviate the heat sink effect in urban areas, and to lessen rainwater runoff (permeable surface). But green roofs are branching out – literally. Modular trays are a new innovation in green roofs (BioTray® plant trays); helps with larger surface area projects; Roof slopes mimic terrain of SF
  • Extensive roofs, because of the shallower growing depth, are better for pre-existing buildings that don’t require significant retrofitting of the roof to carry more weight. Limitation: good for drought-resistant grasses, but not for a full garden. Also, public access can create a fire hazard if people smoke
  • Brown roofs are meant to mimic “brownfield" sites, critical habitat for many species since World War II that have been redeveloped, ironically threatening London’s biodiversity; "brown roofs" made from recycled crushed concrete and brick aggregate for the rare and protected black redstart (source: www.urbanhabitats.org); Primer: www.brownroofs.co.uk
  • A pilot project for the Urban Farming Food Chain, consisting of four locations in downtown LA. The project is now being expanded to include New York, Rochester, Detroit, and Las Vegas.
  • Educational and rec programs focus on health and nutrition, performing arts, technology, physical fitness, civic engagement and leadership development. Plants: vegetables, fruits, flowers, herbs and grasses (comprehensive educational program developed by the center’s garden manager). Learning process: seed-to-harvest cycle, environmental issues, the green roof, botany, cooking, and gardening. Question: can green roofs promote community in a way that boosts inner city neighborhoods? What are the limits? Costs?
  • Green roofs can add considerable value to residential and commercial properties, like this two-tiered green roof condo building in South Boston. An additional bonus: limiting rainwater runoff (with permeable paving stones in entry court) Slanted roof = visible model for neighborhood? But these roofs can also raise questions: a lap pool may be good for attracting tenants, but what’s the trade-off (perhaps a compromise solution from a full-sized pool?). Also, accessible roofs mean additional maintenance and safety precautions, including no smoking regulations for some.
  • An example of combination structures: this one combines green roof, water catchment systems and photovoltaic panels. So is it a technological advance? Experts might say yes. But is playing bocce ball on this green roof really green? That gets into more of the psychology of it. Same vein: City Center in Las Vegas, 1 Bryant Park in NYC; skyscraper in Santiago – huge buildings, so argument is: why not make them green?
  • Argument from Key West homeowner: white roof is a “solar device.” Therefore, should be allowed. Historic Architectural Review Commission disagreed; now formed: Key West White Roof Initiative PAC
  • LEED includes context of the building in its scale, but not every rating system does, leading to grumbling that some “green” buildings aren’t in pedestrian-friendly or sustainable locations
  • Appliance people will tell you that almost everything gets an ENERGY STAR rating now; so does it mean anything?
  • Plus: no shortage of organizations or companies jumping into this; Minus: how do you decide who’s both unbiased and experienced enough to make the call for consumers?
  • Terms you’ll be hearing far more of in the future; probably good to get acquainted with them now.
  • Psychology of green building: consumers need to understand in plain terms what they’ll be getting out of green add-ons. One question: how well are private and public programs actually explaining the benefits of different green systems? Journalists may need to prod some officials to get past their jargon-heavy “greenish.”
  • Ex: Cleveland-based Pro Energy Consultants (founded in 2008, now 54 franchises) www.proenergyconsultants.com Silver Star program will provide up-front rebates for the installation of specific energy-saving technologies, including insulation, duct sealing, windows and doors, air sealing, and water heaters (up to $3,000 in rebates). Gold Star program rewards homeowners who conduct a comprehensive energy audit and implement a full complement of measures to reduce energy use throughout the home ($3,000, or half the cost, for measures that reduce energy use by 20%, and can receive up to $8,000 when additional energy savings are achieved). Scams: Audits as marketing tools for window, door and solar companies; false claims about potential energy savings of specific products; misleading information about rebates and tax credits; solar panels sold for homes that are ill-suited for it (shadows, poor orientation to the sun)
  • New York-based Ecological (Co-founder & board member: former NY Gov. George Pataki); Kimberly Phipps-Nichol is based in Nevada
  • Many other growth industries can be found by visiting a local green expo – most of these will have ample representation from the building industry (Twitter is a great source for finding recent or upcoming ones)
  • Solar panels and geothermal-based heating systems for homes can be a great solution, but many consultants say homes can be green without them.
  • Settling, how effective it is at creating a tight vapor barriers, toxicity, potential for rodent infestation, cost, geographical source of materials: all are considerations for insulation
  • Air-sealing qualities are really important, because air will find the weakest point and escape. A high-quality bucket is useless if it has a big hole in it. For Robin Pharo, the key in green building is to have this conversation.
  • UltraTouch from Bonded Logic made in Chandler, Arizona
  • Technically, bamboo is a grass, it readily re-grows and doesn’t require pesticides. Also, some suggestions that other forested areas are being cleared to plant more bamboo. Traditionally, most bamboo flooring companies lacked certification, but this is changing; also, as the formaldehyde issue gains more press, many companies touting lower levels; LEED gives points for sourcing building materials within 500 mile; (hickory, oak, maple)
  • Questions: Can an “eco-aware” wood source help with reforestation? Weyerhaeuser: Plantations include eucalyptus hybrids + native tropical trees on former agricultural and grazing lands (reforestation); Eucalyptus are also very susceptible to fires – is that a concern? Not a lot of independent reporting on Lyptu; wood is heavy and durable, darkens with age
  • Early predecessor made from soy protein and fibers from recycled newspapers; claim is that hulls and paper waste would otherwise have been discarded; (Other examples: TimberTech, Fiberon, Trex, Azek); rice hulls = outer husks of rice grains; Another claim: “As compared to wood decking, all composite decking products are much more eco-friendly and sustainable.”
  • OK, sward is a stretch, but it fits (sod, turf); Example shown here is porphyry (natural store) and an aggregate, turf, and spreading thyme in the joints; Green cement is also a HUGE endeavor right now, with multiple companies in the mix. California-based Calera makes cement by transforming carbon dioxide from power plants into carbonate. Other companies use calcium magnesium particles; some claim eye-popping abilities to actually absorb carbon dioxide from the atmosphere. More examples here: http://www.newscientist.com/article/dn18885-green-machine-cementing-greener-construction.html
  • Other features: Former brownfield site, accessible by public transportation Brownfield site is an abandoned commercial or industrial space; U.S. Department of State has come up with a 184-page “Green Guide for Embassy and Consulate Operations” OBO Green Team www.state.gov/obo/c29962.htm
  • Juliet Rice Wichman Botanical Research Center Other features: Permeable sidewalks, water-efficient endemic plants for landscaping 2008 blog on building’s features: http://ntbgfellows.wordpress.com/scientific-research-and-education
  • The inclusion of “eco-reps” is critical. One criticism of LEED standards is that they don’t address what happens in an occupied building. But these students do, and peer-pressure can be powerful psychology. Also signifies the growing use of Energy STAR for commercial buildings (label is seen as desirable)
  • Blog about Unity House: http://livinggreeninunityhouse.blogspot.com
  • 1 st net-zero high school in U.S.
  • All building products from Green Depot ( www.greendepot.com ); Interior features from reclaimed/ reused items (recycled glass flooring, service line, oven); Gray water bathroom system (sink water used for toilets)
  • Another example: The Collective Café in Manhattan; interior design all from reclaimed items.
  • Montgomery County: up to $5,000 for commercial property; PG&E = Pacific Gas and Electric Company; If All Politics Is Local, What’s the Impact on Green Building?
  • All politics is local, right? But with the right combination of sticks and carrots, some cities, states, etc. are convinced they can become far greener; one big reason: it’s widely believed that most buildings now are wildly inefficient. A 25-30% improvement then, is very feasible (see white roofs)
  • “ Smart Grids” and LEDs can reduce energy consumption, BUT so can dimmers; 5% drop is an amount imperceptible to the eye; Energy dashboards can provide real-time information on energy use, but an adjustable thermostat could keep you from getting overheated by the bill; triple-pane windows and solar reflective films are great, but opening your windows can lessen the need for A/C and improve indoor air quality; Consumers want to do the right thing, but sometimes “smart” grids aren’t so smart. Consumers don’t like on-again, off-again dryers that result in wrinkled clothes

  • 14. “ Put simply, a building’s LEED rating is more like a snapshot taken at its opening, not a promise of performance. Unless local, state and federal agencies do their part to ensure long-term compliance with the program’s ideals, it could end up putting a shiny green stamp on a generation of unsustainable buildings.” -Alec Apelbaum, “Don’t LEED Us Astray,” NYT May 19, 2010 LEED: A Point of Departure, No Longer the Destination
