The iconoclastic owner of the San Jose tract home featured in this article takes exception to the notion that green is expensive. Green, to him, is rooted in conservation of all resources, not the least of them being money.
Frank Schiavo’s compact, tract-built, three-bedroom ranch-style home in a modest San Jose neighborhood demonstrates that remodeling to create a cutting-edge green home is neither difficult nor expensive. Heated with sunlight and cooled by night air, his home is comfortable, quiet and tasteful, filled with light and local art. With only modest investments in a sun room, extra insulation, new windows, a very small array of rooftop photovoltaic and solar hot water panels, his electricity bill for the coldest, cloudiest months of the year averages a few dollars a month. His gas bill is even more modest.
What’s most impressive about Schiavo’s house isn’t that it’s so comfortable and practical for him to own, it’s that it demonstrates that lofty resource conservation goals can be achieved on a modest remodeling budget.

What is Heat Exactly?
If we’re going to talk about better ways to heat a home, we’d better have some idea of what heat is. What you experience as heat is just the energization of the molecules in your body. Heat is the energy that gives those molecules kinetic (vibratory) energy.
Obviously, your body produces its own heat through the metabolic process (burning calories); the important thing is that your environment neither inundates you with excess energy (when it’s too warm), or draws too much energy away from you (when it’s too cold). This begs the question, how does your environment give or take energy from you?

Author’s note: the following article on home heating is the first in an eight-part series. The series specifically targets climate found in the San Francisco Bay Area, but has applicability elsewhere.
According to the U.S. Department of Energy, heating and cooling amounts to 46% of all energy consumed by our homes. Water heating uses another 14%. In coastal California, where extreme heat is rare and winters are mild, a properly sited, well designed passive solar home can generate its own heat and hot water, and do without air conditioning.
Historically, few homes are so well sited or built. Since our area has more heating days than cooling days, most homeowners need a heating system. What few know is that many indoor air quality problems can be by-products of forced air heating, ventilation and air-conditioning (HVAC) systems installed in their homes.
