Are some of your bedrooms too hot or too cold? This is a common problem in new homes. Often the master bedroom will be fine, but the other rooms get too cold or too hot during the night. The culprit is not necessarily your Heating and Air Conditioning unit. The culprit is the closed door.

Your guests won’t tell you if you have a problem. They’re too polite. Your kids probably have their door open when they are small and don’t have a problem.  Your teenagers probably don’t talk to you much anyway. How can you know if there’s a problem? It’s a good idea to spend a night in each of the other bedrooms in your house, particularly the guest room, if you have one, to see how the temperature goes with the door closed for eight hours. And do this on a cold night and a hot night. You might be surprised at what you find. (more…)

It’s freezing cold across much of the United States. Are you wearing passive solar clothes to stay warm?

I know it sounds like an odd question. We tend to think of using solar design for houses, not clothes. I’ll explain.

If you know it’s a cold day, do you think about what you’re going to wear? Of course you do. You might wear several layers. The layering forms more tiny air spaces around you and increases the insulating effectiveness of your clothing. You might pick out dark colors. Even if you don’t think of this as “passive solar dressing,” it is. dark colors absorb the radiant energy from the sun better than light colors. I’m sure when you’re outside on a cold, but sunny day, you walk on the sunny side of the street to stay warmer than you’d be on the shaded side. Ah! Passive solar principles, again. It’s nothing more than proper insulation and receiving the free energy benefit from the sun. (more…)

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…)

Over the years, I have seen a strong trend away from wood-burning fireplaces toward gas fireplaces.

There are two reasons for that. First is the cost. Traditional, all masonry fireplaces are very expensive to build. The entire chimney must be built of masonry and the tall column of cement blocks, bricks, and terra cotta flue liner is very expensive. Plus, a true masonry fireplace requires a foundation to carry the weight. That adds more cost. Pre-fab metal units have taken over the marketplace for cost alone. Some pre-fab fireplace companies are Heatilator, Majestic, and Heat-n-Glo. These fireplaces have some limitations on the size of the firebox opening. If I need a particularly large opening, I turn to Isokern. This is a fireplace that is made of a special type of concrete block system, but it does not require the full masonry flue. So it is a compromise between the design freedom of the traditional masonry fireplace and the cost benefits of the pre-fab units. (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…)

    The days of “Living Large” may be numbered. House design is changing. We might soon be bragging that we’re “Living Small.” With the current economic conditions, we are seeing our dreams and desires in a whole new light. High energy costs, environmental concerns, maintenance costs and the cost of the house itself are strong motivators to reevaluate one’s needs and create a house design that responds to those needs.

    I think the best way to reduce your living space is to write out what we architects call a “program.” This is the first thing i do when doing a house design. This is a list of needs and desires plus a target size for the spaces you want. It’s a good idea to multiply out the areas of these rooms, include hallways, closets, stairs, and other small spaces and add them up to get a total. Take that total and multiply it by 1.15 to add 15% for the area the walls themselves take up. You’ll end up with the total square footage your house design will need to include all that you want. If this total is too much, go back and reevaluate what rooms and spaces you included. Trim out the excess. I discuss this process at length in my book, Designing Your Perfect House. A good, well thought out program will become your road map to the right sized house design. (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…)

      Do you want to control your homebuilding costs? Do you have electrical plans for your new house? Many stock plans show some electrical information, i.e. the location of switches, light fixtures and electrical outlets. Chances are this layout will not meet your needs, if you have a plan at all. One of the primary sources of homebuilding cost overruns is in the electrical work. If you do not have a well defined, complete plan that shows every switch, which lights each one controls, every electrical outlet, every telephone jack and every television jack, you will not have a guarantee that the contractor is planning on providing what you want in his contract price. I’ve seen people add numerous additional devices only to be shocked when the electrician tallies up the final total and presents the customers with a bill for the extras. Even if the cost is only $30 or $40 per device, they can add up fast and you’ll find yourself with thousands of dollars of homebuilding costs you never anticipated.

      Many electricians base their price on the number of junction boxes they install. Each switch, each electrical outlet and each light fixture counts as one box. So if you add an overhead light and a wall switch, this counts as two boxes. Usually, the location of the boxes does not matter. It is the number of boxes that is critical to your homebuilding costs.
