Reading an ASLA interview of Jose Alminana, a principal at Andropogon Associates, we were reminded that Sidwell Friends School, the Quaker school of choice for the Obamas, the Clintons, the Gores, the Bidens, the Nixons — practically every member of Washington’s politocracy, except for the Carters, of course — has in the courtyard of a recently renovated building an artificial wetland.

Not merely an eco-ornament, it’s a machine that “manages all the wastewater generated by the building, as well as all the rain water that falls on the site.”

Typically, wastewater is drained away via a complex network of tunnels that requires vast financial resources just for its maintenance, an infrastructure that’s undoubtedly deteriorating just as fast as tax revenues get siphoned off away from public works budgets to General Motors and Bank of America. Miles and miles away from its point of origin, the water then gets treated in an energy intensive process. But it still isn’t entirely clean afterwards. Thus, when discharged, it still poses a risk to bodies of water, contributing in many instances to elevated bacterial count and eutrophication.

At Sidwell, wastewater is treated on-site, somewhat off-the-grid and using comparatively minimal infrastructure. The treatment cycle begins inside the building in a tank filled with anaerobic bacteria. Among other things, these bacteria help break down solids. The effluent is then pumped outside to a trickle filter before continuing on by gravity to a series of tiered wetlands. To lessen the health risk of contact with students and to mitigate any odor problems, water flows through beneath layers of pea gravel; there’s no surface flow, in other words. This planting medium contains phytoremediating plants which, together with the microorganisms attached to their root hairs and to the gravel stones, extract contaminants from the water. After slowly trickling its way outside for about a couple of days or so, the water then re-enters the building and gets collected in storage tank ready for reuse in flushing toilets, among other uses for greywater.

Just as with wastewater, managing urban stormwater typically involves massive infrastructure to dispose runoffs as efficiently and as quickly as possible. In addition to being a drain on municipal coffers, such a method is known to increase the probability and the intensity of a flood event during major storms, endangering human life and property. Moreover, since stormwater isn’t allowed to remain where it falls, (1) water doesn’t have enough time to infiltrate the soil and seep into waiting, possibly depleted groundwater aquifers, and (2) what may have been clean at first contact with the surface undoubtedly will not remain so as it moves through sidewalks, roads, parking lots and sewers before going on to pollute rivers, lakes and other sources of our drinking water.

At Sidwell, we get a hint of an alternative system for stormwater management: hyperlocal, lo-fi, modular (i.e., implementations at multiple sites would be needed to bring about an appreciable effect on urban hydrology), soft and comparatively cheap.

Runoff is directed to a rain garden and a permanent biology pond located downslope from the tiered wetlands used for wastewater treatment.

Some of the runoff gets in an underground cistern. During dry weather, this storage tank provides water to the pond. During heavy rains, excess water flows from the pond into the rain garden, simulating the hydrological dynamics of a floodplain environment. Water seeps through the soil and gets naturally filtered.

Andropogon describes this project as a “working landscape” but we might prefer calling it an “event landscape,” wherein natural processes are co-opted into a cybernetic amalgam of landscape, architecture, geology, biology and institutional pedagogy. Rather than in the inaccessible subterranean voids and in scientific abstractions, this eco-machine is made to perform out in the open for the edification of the elite who, in their dirty, smelly, real-world engagement with the landscape, will hopefully turn into great stewards of the earth.

As the credit crunch makes it harder than ever to obtain financing from lenders, some real estate players say an environmentally friendly portfolio may offer builders an advantage in securing funds to develop new projects.

“In general, financing anything is really difficult, given the credit crunch,” said Robert Politzer, president of Greenstreet Construction Inc., a New York-based builder with a New Jersey office in Princeton. But given the growing popularity of green building, developers who do not have green projects are at a competitive disadvantage, he said. “It would be easier these days to interest a potential funding group, whether a bank or private equity, in building a state-of-the-art green building than a conventional building project.”

Because of the benefits of green building, such as energy efficiency and reduced operating and maintenance costs, “you’re going to see increased tenant demand,” said Jim Lutz, senior vice president of development at Liberty Property Trust, a Malvern, Pa.-based commercial real estate developer that recently completed its first LEED-certified New Jersey project in Mount Laurel. LEED, short for Leadership in Energy and Environmental Design, establishes criteria for the design, construction and operation of sustainable buildings under the U.S. Green Building Council.

Higher demand means higher occupancy rates at green buildings as compared to conventional buildings, so “a lender who’s concerned with making sure that the loan gets paid back is going to see it as a less-risky investment,” Lutz said.

But while a green component may help to attract interest from lenders, it ultimately does not determine whether a building gets funded, experts say. “It’s much more subtle, how building green influences financing,” said Michael Saltzman, a partner at Newwork, a Newark-based real estate development company. “It’s more of a secondary factor.”

Less than two months ago, Newwork closed on nearly $17 million in financing from PNC Bank for The Richardson Building Lofts, a 67-unit, 86,000-square-foot, LEED Silver-proposed apartment building on Columbia Street in Newark. The project, which is the conversion of a former jewelry factory, broke ground Oct. 22, and is expected to be available for occupancy by next summer, Saltzman said.

“If a deal came into us that had green attributes, we’d be excited to see it, and we’d consider those as part of the overall underwriting,” said Bill Lashbrook, senior vice president of real estate finance at the East Brunswick office of PNC Bank, which has held in-house discussions about developing a green financing program.

The bank noted in its internal documents that Newwork had applied for LEED certification for its project, though Lashbrook said “the deal stood on its own merits,” including the property’s location in Newark, where PNC is looking to invest, and the current strength of the rental market.

The challenge of arranging financing for a green project lies in assessing the value of the building, Lashbrook said. “In real estate development financing and construction financing, the target is always to create enough value in the project so that [the] owner has the ability, whether it’s through refinance or the sale of the project, to repay the bank,” he said. But “we haven’t seen these properties trade in the market, so we’re not really sure how the market has come to value them.”

Many lenders helping to fund green projects are betting when the real estate market rebounds, such properties will bounce back faster than other types of buildings, said Lindsay Napor, executive vice president of Ecological Development LLC, a New York-based real estate developer working on two green residential projects in New Jersey. “People think when the market comes back … there will be a bump in value in those properties,” she said. Ecological Development has secured $90 million in financing for green projects in New Jersey in the past two years, and is working on obtaining money for two others, Napor said.

Rather than seeking loans from banks, Ecological Development has worked with real estate funds; real estate investment trusts, or REITs; and private investors for financing. “Real estate funds and REITs are still fairly well-funded,” said Anthony Sblendorio, the firm’s chief executive officer. “There’s still a desire by funds and REITs to deploy that money.”

Hampshire Generational Fund, for example, has made an equity investment in Ecological Development’s 89-acre green luxury residential development on Mine Brook Road in the Basking Ridge section of Bernards. The project, slated to begin construction in the spring, will include 12 LEED-rated single-family homes, organic agriculture and manmade wetlands for a stormwater treatment system.

The equity stake marks the first time that Hampshire Cos., the Morristown-based real estate investment firm that administers the fund, has committed capital to a green project, according to principal Robert Schmitt. “We liked the green concept,” he said. “We think it’s where the future is going to be for development.”

Hampshire is paying for improvements and entitlements for the property from its equity capital, Schmitt said, but the costs for land acquisition and construction will be far more substantial, he said. “That definitely hinders our flexibility with the capital structure for this project,” Schmitt said. The firm most likely will fund those costs through lines of credit set up with lending institutions prior to the crunch, rather than seeking new financing, he said.

It is uncertain whether Hampshire, which committed to the project in February 2006, would have made a similar investment during the current credit crisis, Schmitt said. “It’d be a tougher deal to commit to today,” he said. Still, “going forward, we expect to increase the number of green buildings in our portfolios,” he said. “They are buildings that are growing in value, because they are buildings that tenants want to occupy.”

About American Rivers

For more than 35 years, American Rivers has been the nation’s leading conservation organization.  American Rivers stands up for healthy rivers so our communities can thrive – protecting and restoring America’s rivers for the benefit of people, wildlife and nature.  Founded in 1973, American Rivers has more than 65,000 members and supporters nationwide, with headquarters in Washington, DC and offices across the country.

Through our work in five key program areas – Rivers and Global Warming, River Restoration, River Protection, Clean Water and Water Supply – American Rivers is working to protect our remaining natural heritage, undo the damage of the past and create a healthy future for our rivers and future generations.


Our Programs:

Rivers and Global Warming

The impacts of global warming will hit rivers first and worst, in the form of increased droughts, floods, and waterborne diseases. Fortunately, healthy rivers boost community safety and security, building resilience against these impacts and helping communities thrive in the face of a changing climate.  To address these issues, American Rivers is:

  • Raising awareness of how global warming impacts river health, clean water, and water supplies, and promoting 21st century green infrastructure solutions that enhance health, safety and quality of life.

Restoring Rivers

Restored rivers and floodplains protect and enhance local communities and support fish and wildlife.  We are committed to restoring our nation’s rivers through:

  • Removing obsolete and unsafe dams
  • Improving the operations of dams, levees and other river infrastructure
  • Significantly reducing losses from catastrophic floods
  • Connecting people to their local river

Protecting Rivers

America’s highest quality rivers provide drinking water, flood protection, fish and wildlife habitat and recreation opportunities.  To ensure that our nation’s rivers are protected, we focus on:

  • Preventing harmful and destructive projects such as logging, mining, drilling or damming
  • Protecting critical watersheds
  • Bringing national attention to threatened rivers
  • Providing an opportunity for advocacy on behalf of rivers

Clean Water

By focusing our efforts on stopping pollution from sewage spills and stormwater runoff, we are working to ensure that our urban and suburban environments are safe for drinking, fishing and boating.  We focus on ensuring clean water supplies through:

  • Protecting wetlands and other natural landscapes that provide clean water
  • Encouraging municipalities to effectively treat stormwater and wastewater, and consider them resources not waste products

Water Supply

Ensuring that our rivers and communities have enough water is critical to supporting a healthy environment and thriving economy.  We must ensure the nation’s long-term water supply through:

  • Blocking expensive and inefficient water storage projects that will damage rivers without providing substantial community benefits
  • Reducing total water consumption through proven water efficiency practices
  • Balancing human water consumption with the natural requirements of rivers and the habitats they support.

WATER FOR PEOPLE

WATER FOR PEOPLE

from Water for People

In the early 1980s, Ken Miller, a former President of AWWA, Wayne Weiss, with Black & Veatch, and John B. Mannion, a former Executive Director for AWWA, shared the heartfelt vision of a world where all people have access to clean water, adequate sanitation and basic health services.

Their vision touched the hearts of other leaders in AWWA. Together they put this idea into motion transforming it into the social responsibility of the water industry. AWWA members provided the unprecedented excellence of the North American water utilities, manufacturing companies and engineering consultants.

In 2007, Water For People provided more than 108,000 people with safe drinking water resources and/or improved sanitation facilities.

By the late 1980’s, AWWA’s International Affairs Committee received a gift from the Ford Meter Box Company, Inc., for John Kalbermatten to prepare a feasibility study on helping people in developing countries. In 1989, the study resulted in a small ad hoc group to study issues concerning the organization’s start up.

In February 1991, the dream turned into reality as Water For People became incorporated as a 501(c)(3) international nonprofit development organization, followed by the establishment of Water For People-Canada as a charitable organization in 1995.

One of our favorite projects mentioned in the AIA/COTE 2007 list of Top Ten Green Projects was perennial Inhabitat favorite Stephen Holl’s Whitney Water Treatment Plant located in New Haven, CT. This project is fantastic in many ways, but the real beauty of it lies in the fact that the 30,000 square feet water treatment facility is sitting under the largest green roof in the state of Connecticut.

The long stainless steel building shown on the images house the extensive operational facilities required for the plant as well as an exhibition lobby, laboratories, a lecture hall, and conference spaces which are used for the multiple education programs that run on the facility. The roof garden design, the largest in Connecticut, expanded the existing wetland area where the site was located.

The shape of the building serves multiple functions. Architecturally the building has been cladded in thin steel shingles. The shingles, due to the shape in which they have been warped, absorb and reflect the heat of the sun preventing the exposed facility from gaining too much heat. Furthermore, the inverse-raindrop shape of the building, as well as reminding us of, well, rain droplets, also helps in reducing the area exposed to the sun reducing the heat gain even further.

The thin profile for the building allows all regularly occupied areas to have easy access to daylight. Furthermore, domed skylights in the green roofs allow daylight to enter the water treatment plant. These domed skylights serve a secondary function, which is that of allowing the visitors to the public parklands to see the water treatment process occurring within in the facility. On the materials side, the stainless steel shingles of the facade are recyclable and reusable. The building also features recycled terrazzo tiles, cork tile flooring, low VOC paints and sealants.

And of course, the most important feature of this facility lies in the way that it handles water for the project as well as how it interprets the processes of the water treatment in the facility below. The project is divided into six areas analogous to what is happening below the surface in the treatment plant. Those domed skylights mentioned above? They sit right above the ozonation bubbling area of the plant. On an area where there is rapid mixing and high turbulence, little streams move along the grass above. Furthermore the facility’s landscape manages the storm water drainage system for the facility, preventing storm water runoff as much as possible.

Turning stormwater into drinking water
Reference: 07/212

A public tasting of reclaimed stormwater will be held during National Water Week in a seminar being organised by Water for a Healthy Country Flagship to highlight innovations in urban water management.

The seminar, detailing how stormwater previously left to flow down drains can be harvested for drinking water, will be held at the Plant Research Centre, Hartley Grove, Waite campus, Urrbrae, on Monday, 22 October at 4pm.

The public seminar has been organised by Water for a Healthy Country Flagship to highlight innovations in urban water management.

Speakers from CSIRO, the Salisbury Council and the National Water Commission will discuss how stormwater innovation is being used to meet Australia’s water challenge.

The seminar will highlight two case studies where stormwater has been used for drinking, historically in Mount Gambier in SA’s south east, and more recently, a project under development at metropolitan Salisbury, Adelaide.

“Dr Peter Dillon, who leads CSIRO’s Recycling and Diversified Supply stream in the  Water for a Healthy Country’ Flagship’s Urban Water Theme, says the process has been used for a demonstration bottling of stormwater as drinking water, which will be available for tasting after the seminar.”

Colin Pitman, Director, City Projects, City of Salisbury, will discuss the Aquifer Storage Transfer and Recovery (ASTR) project, an unique project involving CSIRO, United Water, the City of  Salisbury, SA Water and the SA Department of Water, Land and Biodiversity Conservation.

The ASTR demonstration project will involve about 200,000 cubic metres of urban stormwater being harvested each year via a reed bed and injected into an aquifer to improve quality before recovery from separate wells at drinking water standards.

Dr Peter Dillon, who leads CSIRO’s Recycling and Diversified Supply stream in the  Water for a Healthy Country’ Flagship’s Urban Water Theme, says the process has been used for a demonstration bottling of stormwater as drinking water, which will be available for tasting after the seminar.

Prime Minister John Howard and Environment and  Water Resources Minister Malcolm Turnbull were amongst the first to drink the bottled stormwater at the 17th meeting of the Prime Minister’s Science, Engineering and Innovation Council in Canberra in June, 2007.

The seminar will be introduced by Dr John Radcliffe AM, FTSE, a commissioner with the National Water Commission and Honorary Research Fellow with CSIRO.

Architecture 2030

infromation taken from http://www.architecture2030.org

Credible scientists give us 10 years to be well on our way toward global greenhouse gas (GHG) emissions reductions in order to avoid catastrophic climate change. Yet there are hundreds of coal-fired power plants currently on the drawing boards in the US. Seventy-six percent (76%) of the energy produced by these plants will go to operate buildings.

Buildings are the major source of demand for energy and materials that produce by-product greenhouse gases (GHG). Slowing the growth rate of GHG emissions and then reversing it over the next ten years is the key to keeping global warming under one degree centigrade (°C) above today’s level. It will require immediate action and a concerted global effort.

To accomplish this, Architecture 2030 has issued The 2030 Challenge asking the global architecture and building community to adopt the following targets:

  • All new buildings, developments and major renovations shall be designed to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 50% of the regional (or country) average for that building type.
  • At a minimum, an equal amount of existing building area shall be renovated annually to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 50% of the regional (or country) average for that building type.
  • The fossil fuel reduction standard for all new buildings and major renovations shall be increased to:
    60% in 2010
    70% in 2015
    80% in 2020
    90% in 2025
    Carbon-neutral in 2030 (using no fossil fuel GHG emitting energy to operate).

    These targets may be accomplished by implementing innovative sustainable design strategies, generating on-site renewable power and/or purchasing (20% maximum) renewable energy and/or certified renewable energy credits.

Multiply Your Stimulus Dollars:
14x Stimulus
A Plan for State and Local Governments

With: ICLEI – Local Governments for Sustainability, RESNET, and Veterans Green Jobs
14x Stimulus Plan Download the 14x Stimulus Plan
Take Action to Implement 14x Stimulus in Your Community

What if there was a way for states, cities, and counties to leverage each $1 of federal stimulus money spent to generate $14 of private spending, create 14 times the number of jobs, reimburse the federal government $3, and get $1 back to boot? Well, there is a way, the ‘14x Stimulus’ plan.

The plan, which is being proposed by Architecture 2030 and its partners ICLEI – Local Governments for Sustainability, RESNET, and Veterans Green Jobs is a state/local version of Architecture 2030’s Two-Year, Nine-Million-Jobs Investment Plan. The effectiveness of the national plan in creating jobs and private spending has prompted these groups to propose a public/private partnership to strategically focus stimulus dollars that will enable a full-scale building industry revival while simultaneously addressing energy and greenhouse gas emissions reductions.

The Plan: How it Works
Based on the same principles as the national plan, the 14x Stimulus plan recommends using state and local stimulus money to create a local mortgage buy-down program that offers reduced mortgage interest rates contingent upon renovating or building to meet specific energy reduction targets. For existing homes, mortgage interest rates would be lowered by 1% if, with a minimum homeowner investment in efficiency upgrades and/or renewable energy systems, the home is renovated to meet a minimum HERS 70 (or equivalent1 rating. For new homes, interest rates would be lowered by ½% for achieving a HERS 70 rating and 1% for achieving a HERS 50 rating. Assuming the current U.S. average, 30-year, fixed mortgage interest rate is 5%, the mortgage buy-down program would work as follows:
Mortgage Interest Rates
To qualify for the lower interest rate, new homes need only meet or exceed the minimum HERS 70 or HERS 50 rating. For existing homes, the homeowner must meet both the minimum HERS 70 rating and invest a minimum amount in energy efficiency and/or renewable energy systems. The minimum amount required to be invested is double the cost of the buy-down and is dependent on the amount of the mortgage as illustrated in the following table:
14x Stimulus Plan for State and Local Governments
The Return on Investment: Everybody Wins
The seemingly odd pairing of interest rates and energy reduction targets turns out to be economically powerful, both creating an immediate demand for construction jobs and generating significant private spending. For example, if a homeowner wanted to refinance a $200,000, 6%, 30-year mortgage at a 4% interest rate, the home would need to be renovated to meet a HERS 70 rating (30% more efficient than that required by the latest energy codes), immediately creating jobs by putting construction teams back to work. To qualify for the program, the homeowner must invest a minimum of $16,000 in efficiency measures, thereby generating much-needed private spending. However, even with the cost of the efficiency upgrades added into the new mortgage, at the lower 4% interest rate, the homeowner would pay a minimum of $168 less each month. Add to that an additional savings on energy bills of approximately $60 and the homeowner would save $228 or more every month. In addition, homeowners can take advantage of the $1,500 federal energy efficiency improvement and 30% solar tax credits, as well as any local incentives that apply.

The plan also encourages new home buying with reduced mortgage interest rates of homes meeting a HERS 70 and HERS 50 rating. For each new home sold under this plan, $1 of stimulus money generates about $42 of private investment.

It is this ability to generate large amounts of private spending that so effectively leverages each stimulus dollar. As a result, the 14x Stimulus plan generates 14 times the amount of stimulus funding4 in private spending and 14 times the number of jobs that would have been created by the stimulus dollars alone.

For example, if a city or county invests $1 million of its stimulus dollars and $1 million in additional state stimulus matching funds ($2 million total), the plan would generate $28 million in local private spending and create 434 new jobs. The federal government would be paid back $6 million in new taxes, triple its investment, with an additional $2 million in new tax revenue going into city, county and state coffers. An incredible return on investment. The more money invested, the greater the return.

It is also likely that, with lower rates and increased savings, homeowners will take advantage of the construction team being on site to do additional renovations – fix a bathroom, add a bedroom, remodel a kitchen – spending even more. In this case, the return on investment would be even higher, making this strategy even more effective.

The Urgency: Seizing the Opportunity
The private building sector represents 93% of total U.S. building stock while the public building sector represents only 7%. The economic health of every U.S. industry is tied to the private building sector, especially housing. This includes everything from steel, insulation, caulking, mechanical and electrical equipment, solar systems, glass, wood, metals, tile, fabrics and paint to architecture, planning, design, engineering, banking, development manufacturing, construction, wholesale, retail and distribution. Simply put, if we do not stimulate building construction, specifically, renovation and home building, we will not revive the U.S. economy in any substantive and lasting way.

In order to capture the job-creation and private-spending potential of the private building sector, the new 14x Stimulus plan encourages households off the sidelines and into the renovation and home-buying market. However, there are many other benefits to the plan, including reduced risk of mortgage failure, increasing home values, more disposable income for homeowners, jobs to those who will pay federal taxes, a new market for material and product manufacturers, and dramatically reduced home energy consumption and greenhouse gas emissions. The result is that, with a single solution, we can address the economic crisis, move the country toward energy independence and begin to tackle climate change.

There are few opportunities that come along that allow us to address several major crises at once, but this is definitely one. We cannot afford to let this opportunity slip through our fingers.
