Rethink Energy

Posted: by

Last night Michael Schaal, of the U.S. Energy Information Administration spoke about the outlook for future energy demand in the world and the United States.

Some of what he reported will not surprise you; we’ve heard a lot of this before.

Even with increased interest in renewable fuels, most of our energy needs will be met by fossil fuels. Demand increases with population and income, so demand is expected to increase in China, Russia, and India. Technology is helping us find new sources of fossil fuels. Technology is also helping us save energy; for example, the energy savings from more efficient appliances have helped keep US energy demand steady, even as we use more gadgets like cell phones and laptops.

Schaal pointed out … Continue reading

How can planning influence climate change numbers?

Posted: by

As we start writing the code for the new zoning ordinance, a “big picture” view seems in order. The biggest-picture formula in climate change, called the Kaya identity, is:

F=Pgef

F = Global CO2 emissions (combustion, flaring of natural gas, cement production, oxidation of nonfuel hydrocarbons, and transport) P = Global population (total number of human beings) g = Consumption per person (gross world product divided by population) e = Energy intensity of gross world product (global energy consumption divided by gross world product) f = Carbon used to make energy (global carbon dioxide emissions divided by global energy consumption)

The most obvious thing about this equation – if you remember even grade-school math – is … Continue reading

Old Buildings and Old Energy

Guest Post by Lisa Mroszczyk

Think of all the energy it has taken over generations to build the County’s existing building stock. This expenditure is embodied energy—the energy already invested to process materials, transport them, and finally construct a building.  Demolition wastes embodied energy.  When that waste is factored in with the energy needed to transport demolished building materials to a landfill and the energy needed to construct a new building on the site, any net energy savings typically doesn’t kick in for three or four decades.

Reusing existing buildings conserves energy and reduces construction and demolition debris in landfills. During National Preservation Month, we are reminded of historic preservation’s role in sustainability.

The Brookings Institution predicts that by … Continue reading

energy and beauty in symmetry and repetition

Posted: by

I think there is a particular kind of aesthetic beauty in the simple repetition of forms over large expanses of contrasting landscape. Even more so when those repeated forms provide sustainable energy.  The just-approved off-shore wind farm is one such example, solar “farms” are another.

The well-heeled opposition to the mentioned wind farm has only posed the aesthetic argument that this visual intrusion into the seascape must by definition be negative.  I disagree.  I think it’s quite attractive, calming, and interesting.  I think the connotations only increase our appreciation of the natural environment that serves as the backdrop (or, more appropriately, the visual context/physical participant).  My interpretation is built on the … Continue reading

Project Profile: The Burnside Rocket

Posted: by

Tacking onto Elza’s post on Silver Spring’s future form, I came across this building a few weeks ago and couldn’t help but think of Fenton Village. It’s cheerful, gritty, and almost certainly would feel at home in a neighborhood that already boasts an array of colors, from the similarly red Pyramid Atlantic to the tastefully pink Jackie’s Restaurant.

And while the Burnside Rocket may seem to offer little in the way of architectural distinction other than a few eccentric shutters painted by local artists (which I think are quite neat), between its crimson painted walls is a powerhouse at work. The LEED-Platinum certified structure is built both to last, approximately 300 years according to the project’s website, and operate … Continue reading
