When you get dressed in the morning, do you consider passive solar design principles? Probably not. At least not conciously. But I’ll bet you consider the weather as you choose what to wear? I do. If it’s going to be hot and sunny, I usually choose a light colored shirt that is made from a fabric that breathes.  Experience tells me to avoid black because it will soak up the sun’s heat and avoid a tightly woven fabric because it will trap air next to my skin and make me feel hotter. This is a principle of passive solar design that we use without even labeling it or thinking about it. And you can use these principles in your house design.

Metal roofs, now often referred to as “cool roofs,” can act like your light colored, open weave shirt and keep your house cooler in hot weather. They do this “passively”, that is they use no electricity in the process. Here’s why they work. In an article posted at Classic Metal Roofing Systems website, they list four energy benefits you’ll get with a metal roof. (more…)

You might think your house only becomes watertight when the siding, brick or stone is completely installed. Actually, sidings of any kind, including masonry and stucco, are not as watertight as you might imagine. They are not the last line of defense against water.

I refer to siding, brick, stone, stucco, and other sidings as the “weatherproofing” of the house. These materials keep the bulk of the wind and water out, but even perfectly installed siding material will still let in small, but significant, amounts of moisture. There is no effective way to stop this and it does not indicate the house is poorly built. (more…)

     Electric bills always seem to be going up. Wouldn’t you like to find a way to reduce your electric bill? To reduce our electric bill, we usually think of ways to use less electricity, which is a good thing. You can reduce your electric bill by making your house more energy efficient. You can reduce the wattage in the lights in your house. I’m not a fan of Compact Fluorescent Light Bulbs, as I’ve written in an earlier post to this blog. But advances in LED technology are quickly changing the way we produce light and much lower electrical consumption. Although it helps, changing light bulbs is not the quickest way to reduce your electric bill. You can immediately reduce your electric bill by 20% to 40% by installing a Computerized Energy Management System.

     One company I’ve worked with here in North Carolina is Smart Energy Solutions. They have a computerized system that manages the big consumers of electricity in your house, like water heaters, air conditioners, dryers, and such. Here’s how it works. In the background, without any noticeable change in your daily living habits and convenience, this system prevents the big electricity consumers in your house from coming on simultaneously. The dryer might wait to start its heating element until the air conditioner is done with its cycle, for instance. This prevents peaks in your electrical usage from occurring and levels out your electrical consumption throughout the “on-peak” period. In most places, the “on-peak” period is usually from around 8:00am through early evening during the weekdays. (more…)

Today, we awoke to a freak snowstorm here in Raleigh, North Carolina. I say “freak” because any snow is a rare occurrence in this part of the country. Snow in January is a novel concept in the southeast. Everything, and I mean everything was closed. We were crippled by Mother Nature.

When the flakes stopped falling, we had about six inches of nice, clean snow on the ground. I put on my tennis shoes (I don’t have boots anymore since I moved south) and found my gloves (they were in my golf bag where I left them following a chillier than usual round a few weeks ago) and set out to clear the snow. I don’t use a snow shovel any more. I’m not sure I still have one. I use my leaf blower, instead. It works surprisingly well. It fluffs up the snow and blows it away almost without a trace. I cleared my sizeable driveway in a little over an hour. The best part is my back doesn’t hurt!

The birth of “Building Green” arguably happened in Austin, Texas in the 1970’s. There’s a good article in Ecohome about Austin’s sustainable building program and their continuing progress. But the trigger for Austin may not have been what you might have guessed. Here is the first paragraph of the article by Jeffery Lee:

Austin, Texas – the state capital and home to the University of Texas – has long been known as a liberal bastion in a conservative state, and the city’s residents are renowned for their environmental consciousness. But it wasn’t the community’s mind-set that led to the establishment of the nation’s first comprehensive green building program; it was a nuclear power plant. (more…)

     People tend to not place enough emphasis on the lighting in their homes. It is often taken for granted and as a result, it is poorly designed.  There are lots of things you can do to reduce your electrical costs, improve the quality of the lighting in your home, avoid construction cost over-runs, and make your house more “green.”

      Natural day-lighting is something that has been under appreciated and undervalued in recent decades. But the current renewed concern about green building and high energy costs have changed that thinking. A good architect can help you orient your house properly on the land to maximize the benefits of free day-lighting without resulting in overheating of the house in summer months. In a well designed house, you should not have to turn on your electric lights during a sunny day. Simply placing windows on the southern walls (in a northern hemisphere site) will gain significant daylight, but the costs to cool the house will soar as the house will overheat badly. You will give up more energy money than you will save. Properly designed overhangs are needed, deciduous plantings, and sometimes shutters or shades can be used to maintain control over the natural lighting in your home. Indirect, reflected daylight is best. Direct sunlight is to be avoided. In addition to the heat gain direct sunlight can give, fabrics and carpets can fade under the intense rays of direct sunlight.

These days, nothing strikes fear into a homeowner’s heart like the news that mold has been found in their house. visions of unknown illnesses and physical maladies flash before their eyes, fueled by incredible lawsuits and media hype. But what is the real threat? How much concern should you have? What should be done?

I’ve been perplexed by this issue and I’ve found that it is very difficult to find dependable information on this subject. Part of the reason for this lack of good information is that no one really knows answers with any scientific foundation. I’ve been doing a lot of reading and based on that research, I’ve come to the following conclusions. As you read these, please keep in mind that I am also among the legions of mold non-experts who have voiced their opinions on the subject. But this information was taken from what I thought were reliable sources. Hopefully this will put the mold issue into perspective. (more…)

    When you mention wood floors to most people, they conjure up an image of a narrow board, red oak floor. But times have changed. Now there are many, many choices of board width and species. And many of these choices come at a modest cost increase. I’ve used white oak, antique chestnut oak, antique heart pine, santos mahogany, jatoba (aka Brazilian cherry), Australian cypress, cumaru, lyptus, and other species you may not have ever heard of. The range of color choices and grain patterns is impressive. (more…)

    Passive solar design, green and sustainable building are not new inventions. Who would have thought that we would be returning to the house design principles of more than a century and a half ago?

    I was in San Diego recently and visited the part of town they call Old Town San Diego. I don’t think the buildings are the actual original structures, but they are reproductions that are authentic to the mid 1800′s. One house La Casa de Estudillo, is built in the Spanish Colonial style of the early California settlers. You can see from the photographs that it is built in a “U” shape with a covered veranda wrapping the inside of the “U”. In the center is an outdoor space that is planted and has a water feature in the center. (more…)

    Green roofs are roofs that have grass of other plant materials growing right on top of them. The theory is that the roof will stay cooler and reflect less heat back into the atmosphere.

    There was an interesting article in the Raleigh News and Observer today. It was about how the local Universities are going “green” in an effort to attract students. They discussed some of the green projects, especially the green roof at Duke University Hospital. (more…)
