Improved efficiency through plumbing

One simple idea for improving the efficiency of houses would be to add an array of pipes to dissipate the heat in water used for showers, dishwashers, and the like during the winter. It would effectively increase the efficiency of the appliances and water heater, reducing overall energy consumption. it probably wouldn’t be too expensive, and it would reduce the guilt associated with hot showers. Those who take baths can accomplish the same thing using no special equipment at all – just leave the water in the tub until it cools to the ambient temperature in the room.

A more elaborate version of such a system might be able to use cooler water from the mains during the summer as a less energy-intensive alternative to air conditioning.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
