In your home, let the sun shine in

ASK A BUILDER

By CCHRC Staff

The “Ask a Builder” series is dedicated to answering some of the many questions Fairbanks residents have about building, energy and the many other parts of home life.

Q: Why is it beneficial to have south-facing windows on a home?

Because of the orientation with the sun, south-facing windows bring in both light and heat, which are important for homes in our climate. If you have a lot of north-facing windows, you’re going to lose a lot of heat with not a lot of heat gain.

The amount of heat your home gains from the sun should not be underestimated and sunlight also is good for your mood.

At the same time, some homes can become overheated in months like March, when there is no vegetation to provide shade, and the sun comes directly through your windows. Also, in the summer, the hot sun can overheat your home if your roof does not have enough overhang to shade your windows. Again, trees and other vegetation will help here as well.

Before you build your home, get a sense of where the sunlight falls in both winter and summer. If you are a morning person and you need that morning light to help wake you up, you’ll want to place your windows appropriately. If you like to entertain in the evening summer sun, then put windows in the appropriate place for that. It’s not just about getting light to see and heat your home, think about how light will affect your life in your home.

Q: I want to put a chimney in for a stove, but there are a bunch of things in the way, including a beam. How can I get around that?

It’s always frustrating when you’ve got the perfect place for a stove, but something is in the way. Ideally a chimney should be a straight shot for easy cleaning and proper drafting, but sometimes it just isn’t possible and you’ve got to put an elbow in the pipe. The best place to put an elbow is at the bottom because it allows you to scrub the chimney top to bottom when you clean it and you can still get inside the stove and vacuum out that elbow piece.

Sometimes you can run a stovepipe directly out the side of the house and up the exterior wall. How well this works is case dependent. If there is too much pipe in an uninsulated space, then the pipe can get cold and as a result, some of the smoke will get cold which can cause creosote build up and create a chimney fire hazard. Also, a fire started with a stovepipe that is cold may not draft properly so it may smoke and smolder and even introduce pollutants into your house if it’s not an airtight stove.

Q: What are the advantages of LED lights over those spiral compact fluorescents?

LEDs use less power, have a longer life and are more durable than compact fluorescents. Initially there have been some costs that have kept them from reaching the broad market, but every year brings new innovations in LED technology, bringing the cost down and improving the quality of light they produce. Compact fluorescents contain mercury, so disposing of them is a problem, while LEDs are fairly non-toxic. LEDs also work better than the average bulb in cold temperatures, which is important in our climate.

Optimize Computer Energy Settings and Save 50%

From The Daily Green, March 26, 2008:

Did you know that 90% of desktop computers are not optimized for energy efficiency? If yours is the one-in-ten that is, then pat yourself on the back, and get back to darning your handknit socks by the flickering light of a candle. If you’re like the rest of us, however, read on.

Dutch Harbor wind turbine still standing

From Alaska Dispatch, Tuesday, October 27, 2009:

According to a Business Wire press release (via Reuters), a residential wind turbine installed by Helix Wind Corp. in Dutch Harbor withstood its first major winter storm. The storm brought winds in excess of 80 mph, and the turbine worked perfectly. One of its owners, Joshua Williams, said after acknowledging he sometimes dreads the cold, wet winters, “After this last storm, as I watched our new wind turbine generate the sea winds back at us, it felt good to get even!” Read more here. Alaska Beat’s favorite part? The release made certain to note: “Dutch Harbor’s weather is considered among the worst in the world.”

Questions Linger Over Energy Star Ratings

From NPR, Thursday, October 22, 2009:

Energy Stars are those blue stickers that are supposed to help you choose the most energy-efficient appliances, TVs and other power-hungry gadgets. More than one-third of Americans use them to pick products, according to the Environmental Protection Agency, which runs the program with the Energy Department.

The government says Energy Star is working so well that last year it helped Americans save the same amount of greenhouse gas pollution as is produced by 29 million cars.

But for years, critics have pointed to several flaws in the program that raise doubts about the reliability of Energy Star ratings. For instance, side-by-side and French-door refrigerators can get Energy Stars even though they use a lot more electricity than do fridges with freezers on the top. That’s because the government splits up various types of refrigerators into different categories and judges each separately.

Disabled to get funds for Energy Star items

From the Anchorage Daily News on Friday, October 16, 2009:

The Alaska Housing Finance Corp. is preparing to divvy out Alaska’s comparatively small share of $300 million in federal stimulus money to cover rebates on energy-efficient appliances.Because Alaska got only about a dollar per person — $658,000 — and officials wanted to make it count, AHFC’s proposal limits eligibility to disabled individuals — those who qualify for Supplemental Security Income, said AHFC public affairs director Bryan Butcher. AHFC estimates there are 10,000 such individuals in Alaska.

People living in rural areas would get more to account for higher shipping costs, he said.

Under the plan, which is awaiting approval by the U.S. Department of Energy, qualified individuals in rural areas could get rebates of $500 on refrigerators and freezers and $300 for washers and dryers. Those in urban areas would get $300 for refrigerators and freezers and $150 for washers and dryers.

Energy Star appliances qualify for the rebate, and participants will be encouraged to destroy their old machines, Butcher said.

AHFC is hoping to get DOE approval in time to begin offering the rebate in December, Butcher said.

LED lights — not just for your DVD player anymore

From the New York Times on Sunday, May 10, 2009:

Most people think of LEDs as the lights blinking from inside electronic devices. They are being used increasingly to light rooms, though few people have ever bought them.

“In the U.S., 78 percent of the public is completely unaware that traditional light bulbs will be phased out in 2012,” said Charles F. Jerabek, president and chief executive of Osram Sylvania, a unit of Siemens. By law, bulbs must be 30 percent more efficient than current incandescent versions beginning that year.

Options for monitoring home energy use

From inhabit.com on Thursday, May 7, 2009:

… we’re focusing upon tracking energy usage, since the first step to cutting down on our power consumption is being able to measure it. Smart meters installed as part of smart grid projects will make it extra-easy to monitor home energy use — and while there are numerous smart grid-linked energy monitoring devices coming out soon, there are also are plenty of ways to keep track of your power consumption with an old-fashioned meter.

Solar incentives may light up US homeowners' pocketbooks

From the New York Times on Wednesday, March 18, 2009:

Solar cells adorn the roofs of many homes and warehouses across Germany, while the bright white blades of wind turbines are a frequent sight against the sky in Spain.

If one day these machines become as common on the plains and rooftops of the United States as they are abroad, it may be because the financing technique that gave Europe an early lead in renewable energy is starting to cross the Atlantic.

Put simply, the idea is to pay homeowners and businesses top dollar for producing green energy.

Smart grid could mean teaching consumers how to use less

From the Washington Post on Tuesday, March 10, 2009:

One gizmo allows you to run the dishwasher when electricity is cheapest. Another decides when to fire up the water heater if you plan on a 6 a.m. shower. Another routes solar energy from a rooftop panel to a battery in your garage and the wiring in your house.

Outside, towers equipped with sensors tell the electric company exactly where a storm has knocked out power. The power grid itself can react to trouble, rerouting juice from a healthy part of the system or isolating itself to prevent a larger meltdown.

Tracking home energy usage

From the New York Times on Tuesday, March 10, 2009:

Although home energy tracking devices like the single-outlet Kill A Watt or the whole-house Power2Save unit are gaining popularity in this energy-conscious age, I hadn’t tried one out until my electric bill topped out at $150 in January. That prompted me to invest in an Energy Detective, a device that retails for $145 and promises to give homeowners a telling glimpse into their personal energy consumption habits — and the appliances that consume the most juice.
