In pursuit of happiness – the question of size and architecture

In November of 2014 I wrote about the Not so Big Apartment and of Gary Chang’s clever Swiss army knife style apartment that transforms into 24 different spaces.   I admired the inventiveness of Cheng’s project and the notion of living well in a small setting.

The topic of size comes up a lot at architectural conferences. The issue is an important one for obvious reasons – bigger homes require more energy to heat and cool and more energy goes into the construction materials. Clients however aren’t always so interested in the notion of doing with less. That’s not surprising in the US, home to the super-sized Big Mac and it’s cousin the McMansion.

At HEDS we think big, from the perspective of living well, is beside the point –size has very little to do with the qualities that foster a sense of well-being and happiness. Size is what builders promote in the absence of good design. This is size over substance thinking – size is a false prize.

We share our clients’ goal that our designs should contribute to their happiness and well-being. In pursuit of their happiness, we promote more substantive qualities such as homes that bring richness through CLEVER ideas. Other qualities we pursue in our designs: FUN, COMMUNITY at all levels (between siblings, within the family, with neighbors and the larger community), a connection with NATURE, and last but not least, COOL.

Lewis & Clark Exploratory Center of Virginia: Engaging people is key to a building’s success

We design with the philosophy that engaging people in our buildings is key to a project’s success.  We think a lot about how to create opportunities for discovery, for collaboration, for a conversation with nature… Take for example, The Lewis & Clark Exploratory Center (LCEC).  We designed the roof as an vegetated garden/overlook to the Rivanna River.  This is where a visitor first arrives and the roof signals the building’s larger goals: to connect to the Lewis & Clark story, and to engage the visitor with nature.  The vegetated roof is to be planted with species gathered by the explorers on their journey west.  The overlook, with a replica of a ship in the foreground and the Rivanna in the background, recalls to the visitor that the exploration was carried out by river.  The building also teaches about water, how precious it is, how it is the source of life: the roof water is directed to a riverstone channel that flanks the stairs descending to the exhibit space.  Water is collected in a basin at the entry below and the visitor crosses a bridge to enter the building – again, references to Lewis & Clark’s river journey as well as modern concerns about the environment and the importance of water quality.  The building is designed to achieve LEED Silver, and its many sustainable features are teaching examples for visitors.  Best of all though is how active the center is with community activities.  The building teaches about the Lewis & Clark’s journey, about nature while serving as an ideal setting for the activities organized by LCEC.  It is gratifying to see our goals realized.  IMG_1463IMG_1478

Sustainable design requires creative solutions

A sustainable architect needs to solve for more than would the typical designer.  I liken our process to solving the Rubic’s cube – where all the goals, challenges and givens must be in alignment.  The typical architect might be solving for the nine squares/side cube, we are solving for the 16 square/side Rubic.  Take for instance HEDS-designed RiversEdge House: Good urban design suggested house be sited in alignment with street grid.  Classic #PassiveSolar approach would rotate the primary windows toward south and shade with deep overhangs.  But the street grid wasn’t on a north-south axis.  To solve for both passive solar and urban siting, we angled the front wall toward south while maintaining the overall orientation to that of the street.

This project was designed as part of the RiversEdge community and speculative – we were the developers.  We know first-hand that passive solar takes advantage of free energy from the sun at no additional cost to the builder – a win-win solution.  RiversEdge5-heds

Allison Ewing shares her green design expertise at Hanley Wood’s Vision 2020 Symposium

Allison Ewing shares her expertise on green design at the Hanley Wood Vision 2020 Video Symposium. She discusses why the building is at a Darwinian crossroads and it’s time to evolve an Architecture of the Fittest. Architects must find solutions that are attractive to home developers who will build 75% of new housing in the coming decades. Nature, with 3.8 billion years of R&D has a lot to teach us about adaptive — and cost effective — strategies in a changing environment. Ms. Ewing discusses how bigger is not better, rather connecting people with the landscape is fulfilling, and how creative designers are finding clever solutions to living richly in a small setting. She tackles creating the zero energy home, the use of low-embodied energy materials and new technologies such as 3D printed buildings which will transform how we build. Some researchers are even exploring buildings which are self-assembling, patterning processes on nature.

shape in context

Bermann’s Rule (1847) – members of species are larger in colder parts of their range attributed to surface to volume ratio.

Bermann’s Rule (1847) – members of species are larger in colder parts of their range attributed to surface to volume ratio.

The natural world has many examples of adaptation to climate. The northern white-tailed deer has a lower surface area to volume ratio than does its more diminutive southern cousin and radiates less body heat per unit of mass, allowing it to stay warmer in the colder climate.  The southern white-tailed deer has a higher surface are to volume ratio facilitating heat loss through the skin, helping to cool the body.  The former is built to retain heat, the latter to cool.

vtvaThe advent of heating and cooling systems coupled with improvements in the building envelope and cheap energy have led to the homogenization of homebuilding. Compare the floor plan of a developer home in Vermont to one in Arizona. Apart from a little white cladding here and stucco there, the blueprints are the same. I grew up in a 1770’s home in Vermont that was four rooms over four (more volume to surface area). The traditional home in Virginia (where I now reside, apparently I can only live in states that start with “V”) is two over two (more surface area to volume). The former built to heat, the latter to breathe.  Vermont has 6006 heating degree days (measurement that reflects the demand for energy needed to heat a building), Virginia has half that number, 3304.   Vermont has 747 cooling degree days while VA has 1422 (twice as many).  Without air conditioning, modern heating, homes from the 18th century were adapted to conserve or reject heat — a strategy seen in nature and one which, when applied to the building industry, has low first costs. This is a strategy the Developer-Builder can easily adopt. It’s called Regionalism.

the butterfly effect

If a single flap of a butterfly’s wings can be instrumental in generating a tornado, so also can all the previous and subsequent flaps of its wings, as can the flaps of the wings of millions of other butterflies, not to mention the activities of innumerable more powerful creatures, including our own species. – Edward Lorenz, pioneer of the chaos theory

architecture of the fittest – 01

Belvedere Civic Core

Fossil records support a theory on evolution whereby isolated populations, subjected to a new environmental pressures adapt rapidly, often within several or a dozen generations. We humans, occupants of the habitat we callThe World, now find ourselves in a like predicament – confronted by a changing environment, we must adapt and do so quickly, achieving carbon neutrality by 2030 (See Ed Mazria’s 2030 Challenge).

According to the Punctuated Equilibrium theory described above (the debate continues between these adherents and the Gradualists like the feud between the Hatfields and McCoys), the isolated population, having adapted to the new environment, now reintroduced to its original habitat, out-competes its sister lineage.  The homebuilding industry is developer-builder driven (20+ percent of the market is built by the ten top builders). In evolutionary terms, the Developer-Builder is the general population which operates on the premise of stasis.  We, let’s call us Team 2030 – the Ecohome-read’in, LEED-A.P.’in, xeroscap’in, carbon-sequester’in, Greenspec-tot’in, , Biophiliacs — those committed to changing the business-as-usual of the industry — must define a new species of building, one that operates at scale.
