A home is a dynamic system that interacts with it environment and occupants in many ways. Our homes are changing constantly because of energy and material inputs and losses. Walls may last for centuries, the roof for decades, and appliances for years. Food in the fridge may last for days or in my case a few weeks. Interior comfort can change in hours or minutes and light…well, it changes at the speed of light.
We are all aware of the electricity coming into our homes and the dollars flowing the other way to pay the bill. We may be somewhat less aware of the effects of sunlight, wind and rain…unless things are not working well. But in fact sunlight wind and rain can all be working for you, while reducing your out of pocket expense.
Modern high-performance homes are typically 60 percent more efficient than their predecessors. This is mostly due to new insight and technology. Clarifying your goals and home performance measures can help you on a path towards a high performance home. For more info see Earth Metabolics: Green Accounting
