New York Times – The Gas is Greener: A response

Thursday, June 23rd, 2011

Robert Bryce’s June 7, 2011 Op-ed in the New York Times “The Gas is Greener” zeros in on a fundamental fault in the logic of depending on solar, wind and other renewables as primary sources of energy.  As Bryce correctly points out, generating large quantities of electricity from renewable sources requires vast amounts of natural resources — most notably, land, not to mention the energy and resources expended to collect and distribute that power that could be generated.

These realizations aren’t new. Interestingly, in 1993 Carl Stein notes in “Energy Conscious Architecture” for the National Council of Architectural Registration Boards (NCARB) that a report from the Energy Policy Project determined:

“From 1965 to 1973, U.S. energy consumption grew at the annual rate of 4.5 percent. This is doubling roughly every 15 years. If we could, miraculously, switch to total solar power in 1995, and if this switch created a return to the “cheap energy” attitudes of the 1960s with the associated exponential growth, by 2010, we would have to devote one percent of our land area to solar collection; by 2025, 2 percent; by 2070…10 percent of the United States would be taken up by collection systems; and before 2110…solar collectors would completely cover the United States.”

Clearly, there is no “silver bullet” to meet our demand for energy consumption and when considering the environmental impact of creating such systems the attitude that renewable energy is the answer is, in fact, directly contradictory to an environmentally responsible point of view. As Carl further points out, “…we must never fall in the trap of thinking of [renewable energy] as easy, cheap or environmentally neutral.” Simply put, there is no free lunch.

The best and most immediate solutions to address the demand for energy are by decreasing the rate of consumption through conservation, resourceful planning and energy conscious design.

Does Saving Historic Buildings Really Save Energy? – A response

Thursday, April 28th, 2011

In a recent posting on BuildingGreen.com, “Does Saving Historic Buildings Really Save Energy?” Tristan Roberts pointed out a number of benefits that may be realized by the adaptive reuse of older buildings; however, he dismissed the notion that there is value in the energy embodied in these structures.  While he is correct in his assertions about the cultural and urban value of historic buildings, he misses the point, or at least part of the point of the value of the energy embodied in those buildings.  Despite the fact that there is no way to “recover” the embodied energy in old buildings, if their reuse offsets the need to build replacements, the energy that would have been embodied in those new buildings is saved – avoided cost.

Of course, there will almost certainly be some construction, and therefore some energy commitment, required to extend the useful life of older buildings including implementation of measures to significantly improve performance.  The net avoided energy cost will be less than the total energy cost on the new building.  Nonetheless, the new energy that must be “embodied” into the existing building will typically be 1/3 to 2/3 that of starting from scratch.  Additionally, there is that much less debris sent to landfill and that much more “embodied” culture carried forward.

Elemental Hosts ‘Greening Modernism’
Launch Party

Monday, December 13th, 2010

Last Thursday, December 9th, Elemental hosted the launch party for principal founder Carl Stein’s new book “Greening Modernism”.  Tom Stoelker of the Architect’s Newspaper writes:

Bodacious bourbon pours complimented savory vittles at the yet-to-be-opened Hudson Clearwater in Greenwich Village last night. The restaurant’s first event launched Carl Stein’s new book, Greening Modernism: preservation, sustainability and the modern movement (W.W. Norton, $60.00). The affair had a decidedly down to earth flavor, though the elegant crowd resembled intermission at The Met. The venue seemed a natural fit for Stein of Elemental Architecture, since Elemental’s John Barboni designed the space using salvaged material culled from the 180-year-old carriage house.

“From my perspective, it fits into all the themes of the book,” Barboni said from behind a kitchen counter made of the structure’s former floorboards. “Green is not a newfound subject for Carl.”

From atop a small flight of stairs Stein thanked his family and colleagues, then settled in with the band to play banjo.

Affordable Housing and Sustainable Action

Monday, September 20th, 2010

The LA Times article – http://www.latimes.com/business/la-fi-urban-green-20100903,0,588562.story – addressing the intersection of affordable housing and sustainable action raises a number of significant challenges as well as highlighting several relatively successful solutions.  Unfortunately, two conclusions, stated or implied, interfere with the simplest, most effective short-term strategies for greening our society.

A primary misconception is the belief that to introduce sustainable measures in low-income communities is problematic because of first cost, and second, that the most effective environmental measures take the form of add-ons such as solar panels.  In fact, many environmentally responsible approaches have equal or lower first costs than their less sustainable counterparts, as well as reducing ongoing operating costs.  Frequently, the only component that must be added is either clearly presented information, or in the case of new buildings or building retrofit, smart design.

This should not be seen as lowering of expectations or of quality of life, but rather as maximizing the usefulness of all resources utilized.  Mt. Airy Woods housing is an example of this strategy.  Completed in 1995, the twelve unit (six one-bedroom, three two-bedroom and three three-bedroom) complex had an average construction cost of just over $50,000 per unit which was very competitive with similar projects of the era.  However, unlike many low-cost housing projects, Mt. Airy Woods incorporated high-performance windows, significantly higher levels of insulation than required by code, responsive heating controls and zoning, earth-buffering, and low-maintenance materials throughout.

The use of higher quality materials and systems without compromising the budget was made possible by providing the maximum useful living space in the smallest possible package.  While the particulars of the Mt. Airy Woods project will not apply to every, or even most projects, understanding their impact is instructive.  The site is steeply sloping, having an average pitch of 1:3.  In general, this would have been considered a serious drawback to development; however, it allowed the design of multi-unit buildings with on-grade, direct access to every unit.  This, in turn, meant that there was no construction for public corridors or stairs.  This not only reduced the amount of building which in itself is a significant environmental benefit, but it also reduced the amount of building area that needs to be heated and maintained.  Further, it improved accessibility and security as well as giving each unit the sense of “entry” and arrival.

This is a limited explanation of a very specific example but is intended to suggest that the careful application of resources, both those that are purchased and those that pre-exist within the boundaries of a project, can address concerns for sustainability while enhancing quality of life issues, and do so within completely conventional budgets.

St. Vincent’s (A Lesson Learned the Hard Way)

Wednesday, June 30th, 2010

The precipitous collapse of St. Vincent’s came as a shock to many, if not most Village residents. It shouldn’t have. Despite the dense obfuscation by the hospital’s administration, there were adequate signs for all to see.  While there is little to be gained from finger-pointing, understanding what went wrong offers valuable lessons for addressing future issues facing the Village, other historic districts and communities throughout the City.

Land is a finite resource and land within historic districts is a particularly scarce finite resource. Institutions, such as hospitals and schools, which deliver services on a face-to-face basis need space from which to deliver these services. In general, serving more people requires more space and one of the claims made by St. Vincent’s throughout the hearing process was that the new building was needed to meet expanding demand for its services. The capacity to add space and to provide for temporary accommodation during renovation, especially in an historic district, is one of the most valuable assets available to an institution.  One need only look at the ongoing problems faced by both Columbia and NYU in finding opportunities to meet their expanding space needs, or, for that matter, the Department of Education’s difficulty in finding locations for new elementary and intermediate schools.  With this in mind, a red flag should fly when an institution that claims to be growing seeks to sell three-quarters of its land, ostensibly to insure long-term survival.  In the case of St. Vincent’s, even had the new building been economically feasible which certainly appears not to have been the case, the sale of the East Campus would have left the hospital so tightly crammed into an architectural straitjacket with so little swing space that accommodating changing technologies would have been very difficult at best, and likely impossible.  Looking only at the physical constraints, the Rudin/St. Vincent’s plan was not a viable plan for healthcare in the Village or, for that matter, for the west side of Manhattan. This, in itself, should have raised skepticism if not outright disbelief.

The financial conditions, even as they were generally known from the time of St. Vincent’s emergence from bankruptcy in 2007 until the impending collapse became publicly known in late 2009, should have given added warning. In 2007, St. Vincent’s was carrying a $700 million debt.  The sale of the East Campus would have covered less than half of that amount. With more than $400 million in debt carried forward, obtaining financing for a new facility that was estimated to cost nearly $1 billion seems unlikely to say the least.  Even if this had happened, it seems doubtful that the hospital could have remained viable while supporting a debt burden of nearly $1½ billion.

And however dark the pre-collapse outlook may have appeared to those on the outside, it was far less dire than the actual conditions, conditions that must have been known to the hospital’s leadership.  Based on reporting in The New York Times and Crain’s New York Business, we now know that the debt has grown to something over $1 billion, an increase of more than $300 million in three years or average losses of more than $8 million per month. St. Vincent’s argued or at least strongly implied that the new building was the key to its financial viability; however, if the project had gone forward and was completed in four years, a highly ambitious schedule, the intervening 48 months during which the hospital would have had to continue in its present facilities would have added yet another $450 million in debt. In other words, given the current debt, the added operating debt incurred during construction and the cost of construction itself, and allowing for the income from the sale of the East Campus, based on what we now know, St. Vincent’s would have moved into its new facility owing more than $2 billion. Even with subsidized construction financing, this hardly seems like a realistic plan.

In early 2010, the public is just beginning to understand the full extent of St. Vincent’s problems. Given the revelations that are occurring almost daily, the emergence of additional concerns would not be unexpected. On the other hand, again based on newspaper reporting including coverage of the recent bankruptcy filing, the people responsible for management and long-term planning for the hospital must have known for several years that this day was coming. Despite this, the situation had reached a point in January that it was only the last minute infusion of millions of dollars from the State and the creditors that prevented the immediate closure of the hospital. The threat was that without a massive bailout, St. Vincent’s doors would be locked within days or weeks at the most. As it turns out, the results are only marginally better with the shutdown spanning a few months rather than days.

What does all of this say to our community, to historic districts in general and to our society as a whole?  First and foremost, we must insist that the critical decisions that affect us all be based on hard facts and, when analyzing these facts, that we avoid diversions. Looking back on the presentations at the Landmarks Preservation Commission as well as at Community Board hearings and other public events, the discussions of adding or removing a floor or two, changing the shape of the curved wall of the tower, the color of the wall cladding or revising the window layout seems ludicrous. A 2015 St. Vincent’s Medical Center $2 billion in debt is not and never was a realistic option. Further, compressing most of the 2008 hospital program onto a piece of land about one fourth of the current site seems so highly questionable that the question has to be raised as to whether it was ever a serious proposal.  Finally, although the $300 million sale price of the East Campus is a substantial sum, it represents only 15-20 percent of the money that St. Vincent’s would have needed to construct its new facility and to clear up its debts. This seems a staggeringly small amount for the abandonment of its prime physical resource.

To recap, from the outset of the discussions regarding St. Vincent’s attempts to sell the East Campus and relocate onto the O’Toole site, we have known, or should have known, that the undertaking would still have left the hospital very deeply in debt and with a physical plant that would have been profoundly problematic if not completely unworkable. That the project got as far as it did is testament to the fact that the developers were able to keep discussions focused on details rather than on the big picture.  We must not allow this to happen again. For decades, the stated mission of St. Vincent’s – to provide health services to the City as a whole – has informed public planning and zoning decisions affecting the site. This has included a number of very significant concessions that would not have been given to other applicants. As such, any plans for the future use of the East Campus must consider how this critical resource may continue to support community or public purposes, for healthcare or other vital services. Until this is done, I believe that it is imperative that any decision regarding the future of East Campus be reserved. As I said at the outset, land, or in this case real estate, is a finite resource. It is also essentially a non-renewable resource.  Once it’s gone, it cannot be reclaimed within a meaningful timeframe. We must not let this tremendous resource be lost to trivial usage.

New York Times Op-Ed: Don’t LEED Us Astray

Monday, May 24th, 2010

In the May 19th issue of the #NYTimes, Alec Appelbaum writes a well positioned Op-Ed piece on the question of green, LEED-rated buildings potentially loosing their luster once in full operation.  Mr. Appelbaum essentially promotes the idea of a creating an incentive program for buildings to go beyond LEED certification, a benchmark that many new construction projects can achieve, and that those buildings should receive credits/subsidies to maintain and promote further energy and resource conservation – a position we fully support.

While we’re fully in support of LEED and the sea change it has created,  Mr. Appelbaum’s view and critique of where LEED certification leaves off is one we also maintain.

Carl Stein – Renewable Energy World North America: “Renewable but Finite”

Thursday, December 3rd, 2009

Carl Stein’s article in Renewable Energy World North America ‘Defining Renewable’ segment is available in print and for download now.

Renewable Energy

As Carl concludes:

“With remarkable shortsightedness, we have come to believe that the petroleum-era paradigm which was made possible by the availability of plentiful, cheap energy represents the natural order. In fact, it is not sustainable and is tending toward catastrophic results. The shift to renewable energies as our primary resources will reconnect us to the cultural/ethical continuum of humankind; a new paradigm.”
