Conserving water, Saving money…

For those of you who have followed the issue, or our newsletters, you know that conserving energy resources can be done for any one of several reasons. As we’ve stated on many occasions ‘it’s not just about climate change‘. The issue extends to national security, economic security and even personal health. So getting on board should be easy. Even if you don’t agree with the scientists and climatologists about global warming you’ll probably still want to save money, and conserving energy is one way to do that.

The same applies to conserving water.

As population grows unchecked, and weather patters change, water resources will become more scarce, whether or not you agree that humans are to blame for global warming. And just like fossil fuels the cost of water will continue to rise. Consequently when you have the opportunity to buy new plumbing  fixtures think about conserving water with low flow shower heads, dual flush toilets and low consumption dish and clothes washers. Even more importantly reconsider your landscaping. If you’re in the suburbs two thirds of your water use is going to support your lawn. Think about it differently by planting drought resistant perennials and other low maintenance plants. Or harvest rainwater and greywater for use in your lawn and garden. And if nothing else learn 100 ways to save water by going here.

Good riddance….

If there is a silver lining in this recession it’s the death of the McMansion. Not only from the perspective of environmental, economic and cultural sustainability but also from the standpoint of design.

I met a local home builder recently who was involved in the construction of these mega homes  and was still promoting his experience using examples of these grotesque icons of a leveraged gilded age. It’s one thing to grasp the waste of resources tied up in one of these environmental and cultural disasters and another to be bludgeoned by its appearance. One can only hope that design professionals were co-opted in the process of delivering these products rather than aiding and abetting their creation.

All too often functional floor plans – reasonably sized rooms arranged in a fashion to compliment their use; and properly scaled exteriors – the placing of appropriate scaled windows and doors, the shape of walls and roofs, and the selection of materials – were totally absent, were out of out of balance with each other or historically misinterpreted by trying to match up some high-brow Renaissance motif with low-brow construction technology or mind-set.

I’m not trying to suggest that it would have been OK to develop McMansions if, in total, they were better designed. My commentary really is meant to illustrate that architecture is primarily a ‘following edge’ art form. Meaning that what gets built is a reflection of where a culture is, not where it’s going.

In the residential arena, architecture, like the culture that it comes from, has primarily focused on the formal aspect of design. The appearance, the surface, the skin and  the shape of a building dominates the conversation, and in a ironic twist, influences more important components. In particular, and for the sake of appearance, the culture dismissed the relevance of a thoughtful development program – connecting with the stated, and unstated, needs of the buildings inhabitants – or the importance of a functional floor plan, where the arrangement of rooms enhance movement and efficiency, and at a subtle level just make sense – or the selection of materials, where it seems enough is never enough, or at least less isn’t more. A concept that, if not applied to materials, was certainly applied to size.

It seems that homes couldn’t be big enough to satisfy an egocentric demand for grandiosity, like a blow fish trying to scare away an aggressor, or at least impress the daylights out of him. Unfortunately the irresponsible desire to display a manufactured image of wealth coupled with an unscrupulous cadre  of enablers in the form of shadow bankers and politicians pushed our economy off a cliff. Consequently the financial capacity to continue this show has pretty much ended. At the risk of sounding simple minded, or coming late to the party, it’s time to re-evaluate what’s important and re-balance the system. In an architectural sense this means  focusing on well designed buildings based on the real needs of its users, not on over blown estimates of self worth.  It also means building in concert with the real needs of our culture, in essence balancing the egocentric concept of ‘me’ with the community concept of ‘we’. And I think that’s a good thing.

Internet HVAC & Lighting controls for homeowners

Schlage Company – the hardware manufacturer, in cooperation with Trane – the furnace and air conditioning manufacturer, has a line of electronic entry hardware (door handles, lock-sets), security cameras, thermostats and add on wall outlets, (like a multi plug that goes into a an existing electrical outlet) that are all able to be controlled over the Internet. Lock or unlock your door, set your thermostat, see what’s going on with the camera, and turn lights on and off (plugged into that add on outlet) all through your Internet connection. Each item is wireless and talks to an  interface that connects to your cable or DSL connection. So when your away from home you can do what you should have done before you left…(did I turn down the furnace?) Go here to learn more.

Coal power plant efficiencies…

Link here to an article about coal fired power plants in China and the US.  This article describes the relative efficiencies of coal as a source for the generation of electricity.

US Energy Flow Trends…

usenergyflows

This chart represents the flow of energy as it is produced from natural resources and distributed to the 4 primary sectors where energy is used; electric power generation, residential and commercial use, industrial production and transportation.

While this chart and the backup report (available here) is 7 years old it is still relatively accurate in terms of percentages of energy production resources and energy consumption sectors. I’ve included it in this post primarily because it has an explanation of the energy losses attached to each sector, which in my opinion is severely under reported and critical to the basic understanding of energy and how we use it.

For instance it’s one thing to talk about the efficiency of a car by rating miles per gallon of gasoline and quite another to understand that a typical internal combustion engine is only 18-20% efficient. In other words 80% of the energy input is lost and only 20% is delivered to the drive train.

Now look at the chart and see the lost energy in the production of electricity. Clearly the majority of energy input is lost in the conversion process of turning the various fuels into electricity and a relatively small percentage reaches your home or office.

While there are thermodynamic limits as to how efficient any given energy system can convert our natural resources into useful work I don’t think it’s critical or necessary to understand the physics in detail.  However I feel it is important to have a global view of how well – or not well – these systems work, how efficiencies can be increased, and where to apply political pressure to ensure that that an appropriate U.S. energy  policy is developed.

Paint technology….

Link here for an article about current – no pun intended – paint technology.

This article is a one page description of photovoltaic and other high tech, high performing paints and coatings.

Energy as a form giver…

southhaven

Hilltop residence near the eastern shore of Lake Michigan.

This drawing is a study model of a residence using wind and solar as the only sources of energy. The form of the house is shaped by the  coincidence of the site topography, prevailing wind, sun angles, views, and the augmentation of a wind turbine with a gull winged roof.

The purpose of an exercise like this is to explore the technology of a self-sustaining building as well as the non-traditional forms that can  result.

This view is an x-ray looking through the topography of the site. Obvious forms are the gull-wing roof, the angled solar energy collector/wall and the partially buried living space.

Off The Grid – The CornCobb House

Horace - A home for the future.

High efficiency home for the future.

Due to its small scale and inherent complexities the real laboratory for architectural innovation lies in residential design.

Pictured above is a sketch of a high efficiency free standing home. This structure is  oriented to take full advantage of  passive solar heating energy delivered directly to mass storage devices such as concrete slabs and trombe walls. Summer exposure is controlled by overhangs and heat loss is controlled by high tech glass, insulation and a green roof. Using active systems like  photovoltaics and custom designed wind turbines we are able to get this home entirely off of the electrical grid .

We’re also investigating the hydrological cycle in order address the issue of water conservation and the affect of this homes water use on natural aquifers.
