Q: What can your average person do to make their home "greener"?

A: Much of green living has to do with conservation of energy use, so sealing obvious air leaks in the shell of the house, providing good insulation in the walls and ceilings, putting thermal curtains on windows in the cold season, replacing incandescent lights with compact fluorescent, and buying energy-efficient appliances are all fairly simple measures that conserve energy.

Q: What kinds of products do you recommend to people who want to infuse green products into their living spaces?

A: I have suggested some of these above, but I would like to emphasize that living "green" is more about consciousness than about "products". If you make it a goal to conserve energy, then you can develop habits of turning off lights that are not needed, etc.

Q: What are some comparisons between sustainable items and non-efficient items for your house?

A: compact fluorescent light bulbs vs. incandescent, solar space heating  vs. electric heating, solar water heating vs. gas water heating, solar electricity vs. grid electricity, front-loading washing machines vs. top-loading machines, clay paint vs. synthetic paint.

Q: I have a question about simply trying to keep our house a bit cooler on days when we are trying not to use the air conditioning. In our front bedroom upstairs, the afternoon sun pours in, heating the room to somewhat uncomfortable levels. We have the windows open to let any breezes in, but eventually I pull the shades all the way down to keep the sun and heat from pouring in. My wife likes to keep the shades up a bit to let fresh air in. I think with the shades up even a few inches that the little bit of sun coming in and bouncing off the wood floors heats the room up and that it is more important to keep the sun and heat out than to let fresh air in as it is more difficult to cool the house down once it warms up. Who's right in this situation?

A: Well, you are both right to some extent, but who is "more right" depends on various factors. First of all, it is really important that any air that comes in that window is able to replace the hot stagnant air in the room. In other words you need to have adequate ventilation above, through the attic and eventually back outside. If this is not the case, then you are probably right, it is likely better to eliminate the sun entering the room.

If you don't already have one, I recommend installing a "whole house" attic ventilation system that will force hot air our through vents in the attic space. This can make a big difference in the build-up of heat in a house.

Having light-colored roofing materials can also help reduce the heat that will enter your house.

West-facing windows are notoriously cookers in the summer. Under some circumstances you might even consider installing insulated shades on those window to block even more heat from entering. Then it is also possible to make air vents that will allow air to circulate from outside without letting the sun in at the same time.

Q: I am building an active adult community of several hundred houses on my farm (Virginia Berry Farm) on which I raised more container-grown fruit plants than anyone else for many years. We sold the business in 2007 but now are transforming it into a place for about 1,000 people to live. I would be very interested in your suggestions as to how to proceed. Am thoroughly familiar with building regulations, county government, construction, etc. It is in the creation of 5-8 story buildings, overlooking a forest, that my questions lie. I have lived in Amsterdam about 9 months of each year since 2,000 so have a lot of experience with conventional buildings.

A: Many of the natural building methods described at this website are not suitable for such tall buildings, but that doesn't mean that you can't employ some of the concepts for sustainable architecture advocated here. For instance, any building can be well-designed for passive solar heating and passive cooling, and employ aspects of water and energy conservation, even providing renewable electricity to some extent. Another aspect of sustainability that housing complexes such as what you are describing could easily employ is the sharing of facilities. Many such strategies are described here. There are quite a few manufactured building materials that can be used in the construction of taller buildings, and many of these are described here. All of these materials or techniques offer some sustainable advantage over conventional wood-framed construction.

Q: How can we make our normal homes green?

A: There are various ways to improve an existing home. Providing good insulation and sealing air leaks can save a lot of wasted energy. Adding windows to provide passive solar heat can help, as can adding thermal mass materials within the building to help absorb and hold that heat for use later when the sun is not shining. Attaching a solar greenhouse can not only provide additional heat for the home, but healthy produce as well.
