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.

When small these children held hands between the window and have grown up to be close friends. Woolen Mills House by HEDS.

Low-energy solutions

We humans, occupants of the habitat we call The World, find ourselves in a predicament – confronted by a changing environment, we must adapt and do so quickly, achieving carbon neutrality by 2030 (See Ed Mazria’s 2030 Challenge). Advocates of biomimicry point to nature, with 3.8 billion years of R&D, as a source for cost-effective, low-energy strategies.  I recently read about the “Ripe Chair,” a project by Andreas Konradsen, part of the DON’T RUN OUT exhibit held in Paris this week, where a steel frame chair was submerged in salt water to naturally weld the joints.  ripe_chair

This process recalls one the Romans used in the production of concrete – they compacted volcanic ash and lime in forms submerged in sea water.  The mix, when in contact with sea water, underwent a chemical reaction to form concrete more durable than today’s.

Those of us architects focussed on sustainability think a lot about creating zero-energy use buildings.  The energy that goes into the production of materials used in buildings is equally important with the embodied energy associated with materials attributed to many years of a building’s life cycle costs.

Among the many materials buildings employ, concrete is the biggest contributor to greenhouse gases (an estimated at 7%).  The Roman’s knew how to produce low-energy concrete, how is it we continue to produce high-energy Portland Cement when there are solutions?  Research into alternatives, such as Belite Cement, is underway and Drexel University has produced a low-energy concrete.  There are other researchers exploring low-energy solutions.  Once these alternatives are on the market, I’m hoping the building industry can move quickly embrace the DON’T RUN OUT philosophy to integrate these technologies into new construction.

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

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.
