“When people are thinking about building a new house they generally work with an architect with a clear opinion on the style, size and rooms that will be a priority. But the most important issue every homeowner and architect should consider when building a new house is the thermal envelope and how the house will work as a system to limit the use of energy and water while also minimizing wasteful and toxic materials. This is an environmentally sound objective as well as a financial and comfort goal.”
