Q: Does it matter what type of wood I burn in my woodstove?

Most species of local wood are suitable for burning in a stove but do not burn wood that has been treated or painted. Regardless of the species, the best wood to use has been properly seasoned and stored. Wood that is fresh, or “green,” contains higher amounts of moisture, which will bring down a stove’s efficiency and cause excessive particulates and creosote buildup inside a chimney.

On a related point, only burn paper in your stove when starting a fire. Too much paper has the potential to produce a fire that is more than a stove or chimney can handle. Burning coal in a wood stove will have the same effect; so do not burn coal unless the stove is rated for it. Overall, avoid burning large amounts of paper or other combustibles that can significantly raise the stack temperature or cause the stove to burn hotter than it is designed to.

Q: I am thinking of installing solar panels on my home or property. What things do I need to think about before I begin?

There are a number of things to take into consideration when looking into a solar power system. First are the cost of electricity and financial incentives. A solar photovoltaic system has a large upfront cost but will provide savings over many years and will eventually pay itself off. Installing a large solar power system and selling the home a few years later will not provide enough time to pay back the investment. However, even pinning down exact numbers for payback can be a challenge since the cost of fuel and electricity both fluctuate. The federal government also provides tax incentives for solar panels and solar thermal systems.

More information can be found at www.energystar.gov. Golden Valley Electric Association’s SNAP program provides incentives as well.

More information on SNAP is available at www.gvea.com/ energyprograms/snap/.

Another challenge is location. Property on the north side of a hill will not collect as much light as a south-facing exposure. Also look at the amount of direct sunlight on a solar panel throughout the day. Shade from trees and other objects will lower the amount of power you make.

Consider the amount of maintenance that goes into a solar power system. Snow and leaves fall on solar arrays and should be cleaned off.

The amount debris can be limited by tilting panels to 49 degrees in the non-snowy months and 90 degrees in other months, which will also help capture more light from the sun’s low angle.

Contact a professional for further information and tips before getting started with an installation.

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

For starters, there are the basics of electrical safety: when you are plugging in anything, you do not want to make direct contact with the circuit because of the risk of electric shock. Besides that, a lot of Fairbanks car fires can be attributed to improperly maintained vehicles. Oil leaks, fuel leaks or other heating elements can be ignited by a small spark. Because winterizing cars in Fairbanks includes installing electrical heating devices, people need to be more cautious about leaks because of the risk of fire.

So if you have leaks, get them checked out and perform any other standard car maintenance.

Could those work in Alaska?

The shingles are going to be covered with snow, so how will that factor into their

East or west might work too, depending on how your roof is built and the pitch of the roof. Consider all the options before choosing a system.

A Heat Recovery Ventilator, or HRV, is designed to bring fresh air into your home. The “tighter” your home is (fewer leaks in insulation, doors and windows), the more essential an HRV is to the safety of the occupants. The other important part of an HRV, heat recovery, means it captures as much of the heat that is leaving the building as possible. You have already heated the air in the house.

To bring fresh air in, you are going to have to expel stale air, but that air has heat in it that you do not want to waste. So the HRV acts as a heat exchanger. As cold fresh air moves in, the warm stale air moves out. When the two air flows pass by each other, the heat from the warm, stale air is transferred to the cold, fresh air through a heat exchanger. These devices will help keep your home warmer in the winter, while saving you energy and money because you do not have to reheat the air coming into your home quite as much.

Increasing sunlight has helped improve particulate pollution in Fairbanks, according to borough air quality specialist Jim Conner.

The average particulate pollution level in Fairbanks on Monday was 40 micrograms per cubic meter of air, making the air unhealthy for sensitive groups, Conner said.

Earlier this month, daily averages were reaching nearly 100 micrograms of pollution, which made the air unhealthy for everyone.

What changed?

Conner said weather fronts have been more active and there’s more sunlight. Both help diffuse temperature inversions, when a mass of warm air sits on top of cold air, trapping fine particulate pollution known as PM 2.5, which can embed in the lungs and make people sick.

“When the sun comes up, usually the concentrations (of PM 2.5) drop dramatically,” Conner said. “When the sun goes down, the numbers will go up.”

There are those who love huge outdoor displays of Christmas lights — life-size reindeer up on the roof and all the trees in the yard covered with glowing bulbs — and those who groan at the sight of a weather-proof extension cord.

If you’re in the latter group, this post isn’t for you. But if you decorate with outdoor lights, you might be interested to find that you can now buy solar-powered decorative outdoor lights.

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.

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.

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.

When clothes dryers account for at least 6% of the electricity used by U.S. households, is it any wonder that line-drying is coming back? In places where the practice is banned as an unsightly nuisance to neighbors, right-to-dry activists and blogging eco-moms are forming an alliance. Their cause: to reduce energy consumption and to call upon sunlight rather than bleach to get those whites even whiter.

The movement also includes homeowners pinched by rising electric bills as well as some celebrity converts. Yes, there’s even a blog dedicated to tracking who’s who in L.A. line-drying. (For the curious, it’s blog.linedryit.com/eco_facts/, which lists the likes of “The O.C.” actress Rachel Bilson and singer Olivia Newton-John.)

This is the second of a series of columns exploring how solar energy can be used at home to reduce your energy costs.

Even in winter, enough sunlight peeks over the horizon to make a difference in your home’s comfort and energy consumption. Last week, we looked at using active solar technology to heat water and generate electricity, but passive solar design is among the most cost-effective ways to improve the energy efficiency and comfort of your home – without a lot of fancy gadgetry.

Passive solar design uses a combination of building features to increase heating and cooling efficiency while improving the feel of your home’s indoor space. Best of all, these features require minimal maintenance, can bolster resale value, and are relatively easy to implement especially if you’re starting with new construction. It’s all about letting the sun shine in.

Solar geometry, site selection, and window technology determine a home’s solar potential. Every building site can be optimized to receive the maximum amount of sunlight possible, but given Fairbanks’s hills, you’re starting off with an advantage if you’re on a south slope or on flat ground. Trees are swell, but strategic trimming or cutting might be necessary to ensure that you’re getting all the radiant heat you’re entitled to (but be mindful of permafrost). Deciduous trees, such as birch, will allow more sunlight to pass into your home during the winter than conifers. If possible, build away from structures that might block the sun’s path.

Once you have a bright site selected, orient your home’s widest section to within 30 degrees of south and along an east-west axis to give the sun as much face time as possible. When placing windows, always consider the angles at which the sun strikes your house. This will affect not only how you shape and locate your windows, but at what height.

Now that you’re in the sun’s good graces, it’s time to ponder the three ways that the sun warms your cockles: By shining on your skin (direct gain); by radiating from objects that are heated by the sun’s rays (indirect gain); and by selectively opening up or closing certain rooms based on their exposure to the sun (isolated gain). Placing the largest and greatest number of windows along the south side of your house will increase heat gain from all three sources.

Direct sunlight is great when it’s available, but you can bank sunlight for later use by using special heat-absorbent flooring and walls that act as thermal masses. Long after the sun has set, these objects will continue to radiate heat into your home. Carpet may keep your feet more comfortable on a poorly insulated floor, but will inhibit solar heat absorption. To cut down on heating costs, use select rooms during the time of day when the sun shines the most and then close them off from your heated living area when not in use.

In the summer, when the sun shines nearly all the time, use carefully measured eves to cut down on glare and help keep your house cool. The overhangs should be wide enough to block the higher-angle sunlight in summer, but allow the lower-angle sunlight through your windows in winter. Landscaping, such as shrubs or yard gnomes, can also help manage your house’s seasonal exposure to the sun.

Next week, we will look at specific window technologies that are critical to passive solar design and insulating your home effectively. When improving an existing home’s solar design, choosing the right replacement windows is especially critical.

“In our view, too much solar capacity has been added relative to demand, and will lead to oversupply,” Goldman Sachs analysts wrote, adding that the consequences would drive module prices down by about 15 percent next year.

Oversupply and an easing of demand as economies slow will help the cost of photovoltaic solar energy fall in line with the cost of conventional electricity — so-called “grid parity” — which will ultimately give the sector a boost, but not before many companies have fallen by the wayside.

A toxic mix of tight credit and falling prices will make it especially perilous for those solar companies with weak cash flows and high debt.

“On a global average, three out of four (solar energy) companies will not make it,” said Robert Schramm, analyst at Germany’s Commerzbank.
