Windows can be a defining feature of a home, enhancing both its curb appeal and interior ambience. But they can also be a major source of air leakage, outside noise and water problems.

Whether replacing existing windows in your home or selecting windows for a new house, making the right choices today can reduce your energy costs, improve comfort levels and reduce maintenance needs for years to come.

One of your first decisions will be about frame material: should you go with wood, vinyl, aluminum or fibreglass? Each has benefits in terms of energy efficiency, upkeep, ease of operation and appearance, so do some research before making a decision.

Another important consideration is whether you want a fixed or operable window.

{Visual}: Close-up detail of the fixed window.

Fixed windows are often the best energy performers because there are no moving parts that can allow air leakage.

If you need an operable window, casement or awning units are generally the best choice since they provide a relatively airtight seal.

For enhanced performance, consider installing triple-pane windows. Make sure they have insulating spacers between the panes to avoid heat loss in the winter and prevent condensation issues.

Solar heat gain is another consideration. By allowing solar energy from the sun into your house during the winter, high-performance windows can significantly reduce your home heating bill. But the key is location, size () and the right type of specialized coatings that can be applied to the glass. Too many south-facing windows can overheat rooms, even in winter.

Exterior shading devices, such as awnings, can help control unwanted solar gains.

Poor installation can affect the performance of even the most energy-efficient windows, so talk to a window specialist and make sure your new windows are installed by a certified technician.

Water heating can account for 25 per cent of the energy bill for many Canadian homes — especially those with large families that use lots of hot water.

Hot water usage can be reduced by installing low-flow shower heads, faucet aerators, insulating pipes, and water efficient appliances.

You may also be able to reduce your water heating bill by installing an “on-demand” or “instantaneous” water heater.

These compact water heaters use high inputs of gas or electricity to instantly heat water as it is needed.

As high-efficiency tankless water heaters don’t have to keep large volumes of water heated 24 hours a day, studies have shown that they can reduce energy consumption for water heating by 40 per cent.

Tankless water heaters can be hung on a wall and require little floor space making them attractive for smaller homes.

But they need to be properly located, sized and installed to meet your household’s needs.

For instance, gas-fired instantaneous water tanks may need different venting arrangements and perhaps larger gas pipes to deliver higher gas flows to the heater.

Keep in mind that the energy savings from an instantaneous water heater can literally go down the drain if their “endless” hot water capabilities just mean longer showers by household members. Whatever system you choose, it’s always a good idea to know the costs and potential savings so you can make an informed decision.

Ask a qualified contractor to assess your hot water needs and recommend a water heating system that will meet them as efficiently and cost-effectively as possible.

If you live in a home with energy-efficient, south-facing windows, you’re probably enjoying lower heating bills thanks to passive solar heat gain from the sun’s rays. In summer, however, this same phenomenon can make your home uncomfortably hot, causing the air conditioner to work harder and your cooling costs to rise.

The answer to this dilemma may lie in outdoor shading devices, such as window awnings and screens, which can limit how much sun enters your home.

{Visual}: Two different types of awnings.

Once a common feature on houses and storefronts, outdoor awnings are making a comeback thanks in part to rising energy costs and concerns about the environment.

Awnings can help reduce a home’s cooling load by about 15 per cent during the summer season. They can also keep the entire house cooler — not just the rooms where the awnings are installed — when continuous air mixing is provided by your furnace fan.

{Visual}: Images of different awning styles and installations, followed by an awning being extended over a small patio.

Awnings come in many styles, colours and materials. They can be fixed or retractable, and can cover large areas like a deck or patio, or individual windows.

Retractable awnings can be manual or fully automated, and some models can detect high winds and close the awning before damage occurs.

Solar screens are a less common outdoor shading technology. They roll down like interior blinds and can do a great job blocking the sun’s rays, but may also block the view.

Most of us take hot water for bathing and showering for granted — until we open our utility bills.

Close to 20 per cent of the energy used in a typical home is for heating hot water — and most of it goes right down the drain. But it doesn’t have to be that way — you can reduce your water heating costs by capturing some of the heat from wastewater.

{Visual}:  Drainwater heat recovery system with copper piping around a drainpipe. Illustration of warm water transfer.

Drainwater heat recovery systems consist of copper piping coiled around a drainpipe. As warm water flows down the drainpipe, some of its heat is transferred to cold water flowing upward through the copper coil.

{Visual}: Close up view of drainwater heat recovery system and piping.

This heated water can then be delivered to your hot water tank, where it helps to warm the cold water provided by your municipality or well.

{Visual}: Water coming out of a shower head and water going down the drain.

This means that your water heater doesn’t have to work as hard to bring the water up to a useable temperature, which reduces your energy consumption and saves you money.

These systems range in cost from $400 to $1,000, plus installation.

Search online for drainwater energy savings calculators to help you determine how much energy and money you can save, based on factors such as shower usage and local energy costs.

Drainwater heat recovery systems need to be properly sized and installed in compliance with local codes and regulations. You’ll want to make sure they make sense for your new home or as a part of a renovation.
