Improving the Energy Efficiency of Existing Windows

Friday, April 29th, 2011

There is a lot to be gained by purchasing energy efficient windows. They can help keep your temperature regulated air in and prevent outside forces from causing your HVAC system to work harder to keep your home comfortable. In some cases, it may make a lot of sense to replace your existing windows with newer, more energy efficient ones, but that is not always a viable option.

So what can you do instead? There are actually quite a few steps you can take to improve the energy efficiency of the windows you already have. For starters, it is a good idea to make sure that all of your windows also have storm windows in place. Storm windows are not necessarily the best, most insulating things you can buy, but they do provide an important extra barrier against air moving between the indoors and the outdoors.

And not all storm windows are created equal. You can certainly opt for the cheapest kind out there, or you can pay a bit more for a product that actually offers a bit more protection against the elements. You will also have to decide whether you want to go for the type of storm windows that are installed on the outside of your existing windows or on the inside. In general, the indoor windows are the best choice, particularly for windows above the ground floor because they are easy to put in and take out and they provide a better seal against the outdoors.

That is not the only thing you can do to improve the energy efficiency of your existing windows, however. Another important step to take is adding weather-stripping around the windows and caulking any areas where air could come through. Even the smallest cracks can cause large losses of heated air in the winter and cooled air in the summer, so making sure there is a good seal all around should be a top priority.

Another option worth considering is the application of one or more different window treatments. There are high-reflectivity films you can put on your windows that will help bounce the sun’s heat away from your home. You can also opt for more traditional sun blockers like awnings and blinds that will keep the sun from penetrating indoors and heating up your rooms all summer long.

Save with Insulation

Wednesday, April 27th, 2011

When you are looking for ways to save money around the house, it can be difficult to know where to begin. However, if you start examining things closely, you can actually find many small ways to cut here and there to save a few dollars. Of course, the savings you will generate by making these moves need to be worth the expense of making them, and it some cases that equation does not work out to your advantage.

For instance, when you are trying to save money on your heating or air conditioning bills, is it really worth it to get a top of the line system installed? Do you really need a 97% AFUE furnace? Sure your monthly heating bills will be lower, but it costs so much to install that it might not be worth it. For some people, the right choice will be to opt for the highest efficiency system, but that is far from a universal truth.

However, there is one investment along these lines that will be worth it no matter what your particular situation is. And that is making sure that your house has proper and effective insulation installed everywhere necessary. Certainly, most houses have insulation of some kind. But do you really know that your insulation is effective and that it is in the right place?

With the new technologies and types of insulation available, you should not have to pay too much to have someone come in to check your insulation and improve upon it. And you very likely will not believe the difference it can make in the way your house feels.

Proper insulation will keep heat in and cold out in the winter and the opposite in the summer. You will quite simply be more comfortable all year round. Plus, you will see a pretty dramatic drop in your home heating and cooling bills because your HVAC systems will not have to work as hard to keep your home comfortable.

This will also translate into less wear and tear on the system over all, making it possible for you to extend the useful life of your HVAC system as well. The savings that can be generated by having proper insulation put in will well outweigh the cost of that insulation in just about every case.

How Can You Improve Your Home’s Air Quality?

Monday, April 25th, 2011

One of the easiest ways to protect the health of your family is by maintaining high air quality in your home. Without good air quality, you run the risk of contracting Sick Building Syndrome or making other problems like allergies or asthma worse. Depending on what type of air quality system you already have in place, there are many things you can do to improve your air quality.

Filter Changes

The easiest way to improve air quality is to maintain the equipment you already have. Specifically, change your filters regularly. Filters each have a specified period of time for which they will last. However, if your home has high levels of larger contaminants like pollen and dander, you may need to change your filter more often.

Beyond filter changes, make sure your filtration device uses high quality HEPA filters, capable of stopping debris as small as 0.3 microns.

Cleaning Your Ducts and Equipment

Another easy way to reduce the load on your air quality system without paying for new filters every two months is to clean the equipment and the ducts in your house. Ductwork quickly gets clogged with dirt, dust, and other debris being blown by your furnace and air conditioner. If you have a boiler and radiant heat system this is less of an issue, but you should still check your air vents and any air conditioner units in your house for excess dirt and debris buildup.

Your air quality equipment should have a specified timeline for regular cleanings – usually every six months to one year depending on the size and quality of the equipment. A lot of this cleaning can be done by you, but for advanced cleaning or parts replacement, you may need a professional.

New Equipment

Finally, you can buy new equipment that does a better job of removing contaminants from your indoor air. If you have only a simple air filter, consider getting a purifier as well to remove other contaminants like smoke and gas. If you have a smaller piece of equipment that works well but longer keeps up with the entire house, there are larger purifiers on the market that can handle a bigger space. Additionally, proper ventilation can help with your indoor air quality if you don’t currently have enough fresh air circulating through your home.

No matter what your problem, there is a solution you can work toward to keep the indoor air quality of your home high.

Does Your Humidifier Have an Odor?

Friday, April 22nd, 2011

The best way to avoid those dry, uncomfortable winters is to have a high quality humidifier in your home adding much needed moisture to your indoor air. This can help lessen the severity of cold and allergy symptoms and even reduce the risk of asthma attacks. But if you notice a strange or musky smell coming from your humidifier when you turn it on, you probably won’t want to use it as often.

Fortunately, a problem like this is relatively easy to fix. That’s because it’s probably caused by stagnant water or a buildup of mold or mildew inside the humidifier itself. This isn’t a particularly pleasant thought, of course, but it does mean that the smell is pretty easy to get rid of. All it takes is thorough cleaning with the right materials.

Before you clean out your humidifier, always make sure it’s unplugged. The first thing to do is to remove the filter and change it. In some cases, that will take care of the entire problem and you won’t have to invest any more time in this project.

If your humidifier doesn’t have a filter or if the smell persists even after the filter has been changed, a deeper cleaning is probably in order. Begin by getting rid of the water in the reservoir and washing it out thoroughly. Next, scrub out all the interior areas of the humidifier you can reach with bleach and water. Make sure you get the evaporator belt while you are in there – it’s a particularly tricky component that can contribute to the musky smell. Be sure to rinse out the bleach thoroughly afterwards or it will be introduced into your indoor air when you turn humidifier back on.

Once that’s done, reassemble the unit and run it as normal with a fresh supply of water. That should solve the problem, but to keep it from happening again, there are some simple preventative steps you can take. First of all, don’t leave water standing in the reservoir for any length of time.

Whenever you’re not using your humidifier, dump out excess water and dry the interior thoroughly to prevent the growth of mold or mildew. You can also add vinegar or baking soda to the water in your humidifier to help keep any unwanted smells from coming back. Ideally, this will never again be an issue for you. If it is, and you have kept your humidifier clean, you may need to have it more thoroughly cleaned or inspected.

Indoor Air Quality – Humidification/Dehumidification

Wednesday, April 20th, 2011

Most people don’t think much about the humidity in their home unless it gets unbearably high in the summer or extremely low in the winter. However, even slightly low or high humidity levels can have a huge impact on your indoor air quality, so even if you feel comfortable most of the time, a humidifier or dehumidifier is something you should look into. Many homes have humidity problems, and even if it’s not something you notice on a regular basis, air that’s too moist or too dry can have a large impact on your family’s health and the overall quality of your indoor air.

The Risks of High and Low Humidity

There are many reasons that proper humidity in your home is so important. For one thing, air that’s too humid promotes the growth of things like mold and dust mites that are significant airborne allergens. Without enough moisture, however, mold and dust mites can’t grow, so if you keep your indoor humidity below 50%, you’ll likely never need to worry about these allergens disrupting your family’s health or causing damage to your furniture.

But, dry air isn’t much better. Once the humidity level gets below 35%, a number of negative things can happen. Dry air enhances the symptoms of asthma, colds and allergies, and it causes damage to the wood fixtures and furnishings in your home. Even if it doesn’t do so much damage, dry air is simply uncomfortable, causing dried out skin, eyes, and hair.

Why Humidity Control Matters

Even if you have a state of the art air quality system installed in your home, humidity is very much something you need to be concerned about. Air that’s too moist or too dry can actually make it more difficult for indoor air cleaners and filters to get those contaminants out. In effect, poor humidity control makes every aspect of your air quality worse.

So if you want to be sure you’re getting the most possible out of your indoor air cleaner, the best thing you can do is put in a good humidification system as well. And when you’ve done that, you may even find that you can turn down the heat and air conditioning as well. Properly humidified air makes home heating and cooling more efficient, saving you both money on your monthly energy bill and wear and tear on your system. No matter how you look at it, proper humidity control is good for you and your home.

Energy Efficient Home Cooling Tips

Monday, April 18th, 2011

Having an energy efficient air conditioning system in place is a great way to keep cool in the summer for less. But that is far from the only thing you can do to help reduce your energy bills throughout the hottest months of the year. In fact, there are several simple steps you can take to start cutting down on your cooling costs right now and lighten the cooling load that your air conditioning system has to bear.

One of the main things to remember when you are trying to keep your house cool is that every door and window is potentially letting in warmer air from outside and letting the cooler indoor air escape. You can cut down on this considerably if you simply take the time to seal up these access points and any others you are able to find.

Putting up plastic over unused doors and windows and checking all areas of the house for drafts and adequate insulation will dramatically reduce the cost of keeping your house cool in the summer. Also, you can keep the sun from warming up your indoor air by drawing the blinds, particularly on those windows that let in the hot afternoon sun.

Putting up light colored siding and reflective roofing will also do a great deal to keep your overall cooling costs down. That is because these materials are able to direct the heat of the sun away from your house rather than letting it be absorbed so that it can heat up the inside. The vast majority of the heat that your air conditioning system has to remove from your house comes in through your roof and walls, so blocking this access point is extremely helpful in keeping your overall cooling costs down.

All of these are steps you can take to reduce the total cooling load that your air conditioning system has to deal with. But if you want your system to continue to function at peak energy efficiency, you will have to take care of it as well.

This typically means having someone come in once a year to perform a thorough inspection of your air conditioning system and to clean out any debris that may have accumulated over time. Having this done will make it possible for your air conditioner to continue to function at the highest possible levels of energy efficiency for years to come.

IAQ – Ultra Violet Lighting

Friday, April 15th, 2011

With a state of the art home comfort system in place, complimented by a high tech indoor air cleaner, you may think you’re set to take on climate and contaminant related challenges to your air quality. But you’re probably missing one thing, and that’s the ability to remove living contaminants like bacteria and viruses from your indoor air.

Unlike non-living particulate indoor air contaminants, bacteria and viruses are not easily caught by indoor air filters or ionizers. They often slip through and continue to circulate again and again through your home, greatly increasing the likelihood that you and your family will get sick. They also tend to reproduce, so the longer you go without eliminating these germs, the more of them there will be.

Killing those Germs for Good

Fortunately there is a technological solution to this indoor air quality problem. The inclusion of ultra violet lights into your air purification system not only specifically targets bacteria and viruses; it helps to slow the spread of disease when someone in your home gets sick.

UV germicidal lights are extremely effective at removing all types of living contaminants from your indoor air. Unlike HEPA filters and air ionizers, UV germicidal lights don’t try to remove these contaminants by trapping them. Instead, they kill them outright, making sure that the germs can’t stick around to reproduce or work their way free of the containment system.

Installation and Maintenance

For most indoor air contaminants, you want to have someone test your air first. However, with bacteria and viruses, you can rest assured that they are always in the air around you. It often only takes a smaller number of pathogens to make someone ill.

Most UV germicidal lights are easy to integrate into your existing indoor air cleaning system. They are usually installed just past the filters so they can catch the germs without other indoor air contaminants getting in the way. And best of all, UV germicidal lights require very little attention or maintenance.

Simply put them in place and let them do their work. You should schedule a routine maintenance visit every so often to make sure that no part of your indoor air cleaning system needs to be repaired or replaced. But other than that, installing UV germicidal lights in your home allows you to relax and enjoy a completely contaminant free living environment.

How Much Can I Save with New Equipment?

Wednesday, April 13th, 2011

There is certainly something to be said for upgrading your current HVAC equipment to newer, more energy efficient equipment. Doing so can save you a ton of money in heating and cooling costs and it can make your home a more comfortable place in general. Of course, upgrading your equipment is a big investment, but ideally you will save enough on your monthly energy bills that it will more than make up for the initial cost of the installation.

But before you can decide whether or not it makes sense for you to upgrade, you need to know exactly how much you stand to save every month by upgrading. And that will vary considerably depending on several particulars of your situation.

For instance, you will have to take the age of your current system into account. No matter how energy efficient your system was when you first bought it, that energy efficiency has almost certainly deteriorated over time. Plus, the older your system is, the less energy efficient it probably was to start with. And the less energy efficient your current system is, the more you will save when you upgrade to a newer, more energy efficient system.

But that is not the only variable you will have to be on top of. The amount you will save monthly and annually will also have to do with how much you use your HVAC system. If you live in a rather temperate climate, you may use your HVAC much less, both in the summer and the winter.

In a case like this, the percentage you will save with an equipment upgrade will be the same as it would for someone who lived in an area with a harsher climate, but the actual dollar value will be much lower. All that really means is that it will take you longer to recoup your investment, but it may still be worth it to invest in a new system now.

You will also need to be aware of other factors that could impact the energy efficiency of your HVAC system. For instance, if your house is not well insulated, it will not matter how good your HVAC system is. You will still be paying more than you should to keep the indoors comfortable, and while investing in a new system may save you money, you will save more by taking care of your insulation problem first.

What Is the Single Biggest Money-Saver Upgrade You Can Make?

Monday, April 11th, 2011

While it would be great if there was a simple answer to this question, the real right answer depends to a great extent on your own particular situation. There are literally dozens of steps you can take to save on your home heating and cooling costs, and which ones are most appropriate for you will have a lot to do with what you already have, how you use it and where you live.

For instance, if you have a well-insulated house but your HVAC system is more than 10 or 15 years old, investing in a new system will almost certainly save you a ton in the long run. Even if your existing system is working well, the newer systems available are simply so much more energy efficient that having one will cut your monthly bills dramatically.

Plus, you will be replacing your system relatively soon anyway if it is that old, so you might as well start saving now on your heating and cooling costs. However, even the best heating and cooling system on the market will not save you that much money if you do not have a properly insulated and sealed house.

Insulation keeps the warm air in during the winter, and it also keeps colder air from seeping in. In the summer, it works the other way around, keeping in the air you are paying to cool and keeping out the hotter outside air. If you do not have thorough insulation or if it is too old, that temperature controlled air that you are paying for will be leaking out and unwanted outdoor air will be finding its way in. You will pay much more than necessary to keep the indoor temperature comfortable as a result.

If you have both good insulation and an energy efficient HVAC system, your thermostat might be the place to look when you want to try and cut your energy costs. A programmable or wireless thermostat might be just the ticket you need to cut back even more on your energy bills because of the added control it gives you to more precisely regulate the temperature inside your home.

Particularly if you have a large house, you might even consider having a zone control system put in so that you can set different temperatures for different areas of the house. After all, there is no need to be paying to regulate the temperature in a part of the house that is unoccupied.

What is a Green Building?

Friday, April 8th, 2011

A green building is environmentally responsible and resource-efficient throughout its life-cycle, minimizing the building’s impact on human health and the natural environment.

Some of the criteria that can go into evaluating a green building include:

  • Location
  • Design
  • Construction
  • Operation
  • Maintenance
  • Renovation
  • Demolition

Of course, there are many different kinds of green buildings, each with its own particular strengths. Here are a few:

Buildings located in New Urbanist communities. New Urbanism is an urban design movement that promotes walkable neighborhoods with multi-use buildings so that residents can live, shop, and work within their local area. The goal is to promote community, reduce the amount of energy used for transportation, and reduce emissions from car travel.

Net-zero buildings. A net-zero building produces renewable energy equal to or greater than the energy the home consumes from public utilities. A net-zero building saves energy by being extremely energy efficient, and by generating its own renewable power using solar, wind, micro-hydro, or geothermal systems.

Ultra-small” homes. Super-small houses (30 square meters and even smaller!) are a growing trend in home design. Tiny spaces dramatically reduce the occupants’ energy use – in some cases, the entire home can be run on the equivalent of a couple of light bulbs.

Buildings constructed with local, natural materials. Homes made of earth, straw bales, stone, stucco, and other natural materials are often cheaper to build and require much less gas for transporting construction materials. They can also be extremely energy-efficient to operate because the building materials are suited to the climate.

Buildings constructed entirely or in part with reclaimed materials. Recycling keeps building materials out of the landfill and reduces the energy needed to manufacture new items. One commonly-used reclaimed material is shipping containers, which are strong, cheap, and can be assembled in a modular fashion to create homes of any size.

R-2000-certified buildings. R-2000 is a voluntary standard administered by Natural Resources Canada (NRCan) that evaluates three main areas of construction: energy performance, indoor air quality and use of environmentally preferred materials. Builders are given the freedom to choose the best and most cost-effective way to achieve the R-2000 goals, which means they can incorporate any of the techniques or building styles described above.

LEED-accredited buildings. Probably the best-known green building accreditation system, LEED offers third-party verification that a home is above average in the following areas: sustainability of building site, water efficiency, energy use, sustainability of materials, use of resources, indoor environmental quality, location, transportation connections, and innovation in design. LEED-accredited homes are extremely efficient to operate and have a high resale value.
