One of the ways to slow the advance of climate change is to reduce your personal carbon usage. While we cant efficiency our way to climate neutrality, we can buy ourselves time by slowing the rate of carbon emissions and conservation, as Negawatts are often the cheapest form of clean energy available (and the least polluting). Also when you have less energy to replace, its cheaper to do so (i.e. if you cut your energy use in half, then only half the renewables are needed to make it sustainable).

Our homes can seem like a monolithic entity they need heat and or cooling, they use water and heated hot water, they consume electricity, and need lighting and plumbing. But the structure plus our actions can alter how much carbon is produced by several orders of magnitude. Two equivalent homes standing side by side could have 5 to 20 times the difference in carbon pollution produced in daily operation. A 100+ year old leaky home with inefficient appliances and high electricity use creating dozens of tons of CO2 a year can stand next to a Passivhaus or Net Zero home, which has very low or even no carbon emissions whatsoever. And there is a huge continuum in between these extremes. Many existing homes that are inefficient can be upgraded to various degrees to reduce their carbon footprints.

This article series is focused on detached and semi-detached homes, but many of the concepts are applicable to all building types.

You can save energy by setting your thermostat to a lower temperature in heating season and a higher temperature during cooling season. This of course will test your familys comfort limits. Many people with programmable and smart thermostats set their houses to be cooler or warmer at night (winter/summer respectively) and also when they are away at work, then have them automatically adjust back to the desired temperature when they are awake or back at home. These daily temperature setbacks will save a few percent of energy because greater temperature differences between indoors and outdoors equalize more quickly (thanks to thermodynamics). For many types of heating this is fine, but for heat pumps and geothermal the time to equalize plus the extra wear and higher rate of change will eat into their efficiency advantage so this is something you should avoid or only go with slight setbacks of couple degrees at most.

Adjust dampers on ductwork to heat or cool specific parts of your home to your comfort requirements. If seldom used rooms can get by with less conditioning then you can adjust them for less hot or cold. If dampers are not installed in your ductwork they can be retrofitted, though some systems do not have balancing abilities, which may be the case for radiator type systems. After making adjustments, observe the results for a few days to determine their steady state effects between changes.

Check what areas of your home are being conditioned. If you have a dirt crawlspace or other unused spots and there are duct separations then fix them so you get conditioned air where you want it to be (though some conditioning can sometimes be necessary depending on layout, consult a building science expert if necessary). If you have storage rooms that dont need conditioning, then add dampers to the ductwork and close them. For many vent designs simply closing the vents is only partially effective. If you have an older home with gaps to outside that are leaking air, then find a way to seal them. This is common in very old homes with brick or stone foundations, homes built before building science understood the impacts of air sealing, balloon framing with gaps to the basement/attic, crawlspaces that were intentionally vented due to obsolete building codes that were later amended when building science advanced, and so forth.

If you have extra rooms you wish to condition, calculate whether its a good idea or not. Garages, sheds, sun rooms, and other auxiliary spaces can be very energy intensive to condition because they are often poorly insulated (or not insulated at all), have high amounts of low R-value glass or leaky garage doors or thermal bridging or metal walls/roofs, and in addition are often very poorly air sealed. They can amazingly have a higher load to condition than your entire house. Consider carefully if this is worth it when deciding whether or not to spend energy or carbon conditioning them. Get an expert to run numbers if you dont have them handy so you have the knowledge needed to make the best decision.

If your current appliances are not very efficient, it can sometimes be cost effective to replace them before they reach their natural end of life. This should be determined by running the numbers compared to higher efficiency equipment and determining the payback period if you replace it. If you are good with numbers you can run this yourself, or you can find energy efficiency auditors in many countries who can run the numbers for you. If its not cost effective to replace it early, the calculus will change when the current equipment wears out. The cost difference between lower and higher efficiency new equipment will typically pay for itself very quickly in energy savings, but think ahead and make decisions now so that when your equipment wears out you are not caught flat-footed trying to figure out numbers when you have no heat or no air conditioning. Dont disregard the possible issues due to planned obsolescence on new equipment. All this being said, even if the numbers dont favor early replacement for economic reasons, if you have the cash consider doing so for the environmental benefits if they are significant. And of course look at more environmentally friendly heating and cooling options, as replacing a high carbon heat source with a lower carbon or better yet carbon neutral electricity should be the ultimate aim.

Your local grid may not be very renewable, and if youre upgrading equipment solely for environmental benefits it is worth figuring out how clean your current electrical mix is and its potential cleanliness in 10/20/50 years and using it in your planning. Bear in mind that any appliance decisions you make will lock you in for possibly decades until the equipment needs replacing. If you have or plan to install solar or wind on your property (or community renewables) this will also affect your decisions.

Often HVAC professionals will use rules of thumb to determine the sizing for new equipment. Do not fall for this, they typically lead to massive over-sizing which can cause the aforementioned comfort problems and accelerated equipment wear and higher equipment prices. Also avoid buying the same size as your current heating equipment, as it may already be vastly oversized, plus a higher efficiency unit will end up even more oversized than what you have now. For example, a 60K 80% efficient furnace puts out 48K of heat, but a 98% efficient 60K furnace puts out 58.8K of heat, 22.5% heat more for the same fuel but even more oversized. You can get proper sizing information from an energy audit or a heating and cooling analysis done by a proper professional. Dont fall for half-assed calculations made out of convenience.

Sometimes HVAC professionals recommend leaving the blower motor running 24/7 to help with comfort complaints or for other purposes. This is a waste of energy and adds wear to the equipment, but can provide better air mixing and a placebo effect on HVAC performance if there is no problem. If there are cold spots that it is addressing, then there is a problem that needs fixing. Whether its improperly balanced ductwork, oversized equipment, separated ducts, duct leakage, blocked vents or insulation/air sealing/thermal bridging problems or something else, it is best to determine the actual cause of the issue and fix it, rather than pay a perpetual energy (and carbon) penalty on a band-aid.

If you are replacing equipment you may also want to consider getting an ECM blower motor, which is far more energy efficient at varied speeds. At full power it will be about the same efficiency as a standard motor, but if you have a two-stage or variable furnace it will save a great deal of electricity at partial load. In a single-stage non-gas furnace, an ECM motor will still help reduce electricity consumption as the primary heat source will handle more of the full load. Also, ECM motors have less startup surge and are often more amenable to being run off generators or battery backup in case of local grid failure. If doing so, make sure the electricity has a clean enough sine wave to avoid damaging the motor.

It is worth reading the heating and cooling sections of my Disaster Preparedness articles Part One and Part Two.

Many companies recommend annual maintenance on new equipment, but it is outside the scope of this article to make recommendations on this, so do your own research.

In the US it is common to have HVAC equipment and ducts in the ceiling. This is incredibly inefficient as this ductwork is outside the building envelope (as these roofs are often vented). The stack effect causes heated air to rise, so even if the ceiling is insulated the heat/air conditioned air is above where the humans reside and the ductwork is often leaky, meaning hot and cold air end up where they least need to be. The ideal fix its to remove and relocate the HVAC appliances to inside the conditioned envelope of the house and air seal the ceiling. This is often not practical in an existing building, and the vents can be buried under the insulation, making it difficult to air seal. Do your best on this one and even consider making the roof unvented by insulating the rafters instead (making it a cathedral ceiling) after consulting professional advice to avoid destroying the roof with rotted rafters or sheathing over time. If designing a new house, do not install HVAC equipment and its ducting in the attic.

Improving The Efficiency Of Your Home, Series 2: Heating, Cooling, (Hot) Water Part Five - CleanTechnica

.......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... ..........

SANTA FE, N.M. I was visiting our friends Joe and Alice Hardy in their home in coastal southern Maine a year or so ago. They have solar panels and wood stoves but, as Joe explained, they also have a heat pump.

What are heat pumps? I asked. Joe tried to explain how heat pumps work. They work a lot like refrigerators, you know, he said, assuming I knew all about how refrigerators work. I honestly didnt understand what he was saying at the time or its implications.

So, what are they and how do they work? As I have since learned, heat pumps are an efficient home heating and cooling system that can save you money. They work because, believe it or not, heat can be extracted from cold air.

Joe was right. Our refrigerators are a lot like heat pumps. But a heat pump has a condenser unit that is outside your house. It yields both hot and cold air, and it also has an indoor unit that passes the hot or cold air into your home. Heat pumps use electricity and refrigerant to move heat from one location to another. A heat pump extracts heat from the air, transferring it to the coolant. When the coolant is compressed, heat is produced. Then the coolant is transferred to the indoor unit, where it releases heat.

................................................................

What heat pumps do is provide heat, air-conditioning and humidity control. In the cold time of year, they move heat from outdoors to your home. In the hot time of year, they move heat from your house to the outside. And, as Consumer Reports states in its buying guide, they are often more cost-efficient than conventional furnaces, which generate heat by burning fossil fuels. The most common are air-source systems. They have both an indoor and an outdoor unit. The refrigerant circulates between the two units absorbing and releasing heat. But Consumer Report says that, if your winter temperatures are below 10 to 25 degrees, you will need an auxiliary heating system.

When this concept is applied to residential heating and cooling applications, it works because, in a heat pump, less energy is used to produce the hot or cold air than the heat or cold generated. And heat pumps work well for both applications. They also improve indoor air quality since fresh air is introduced into your home.

It seems counterintuitive, but even extreme cold has heat energy, and the heat pump extracts it and transfers into your home. However, they are not as efficient in cold temperatures, since more heating than cooling is required. So, in colder climates, heat pumps often require a back-up heating source. And make sure your home is well-insulated before you consider a heat pump. If you have a super insulated home, they could work very well.

There are three basic types: air source described above, water source should you have a nearby body of water, and ground source or geo-thermal. They all gather heat from different sources. The cheapest and easiest is air-source, but they need to be customized for maximum efficiency. Both ductless and ducted systems are available and they can be multi-zoned. All systems sold have an EnergyGuide label that explains their heating and cooling efficiency.

You can get a lot of information about heat pumps at energy.gov, or you can just ask your plumber, like I did.

My plumber referred me to Bob Deeds of Santa Fe Home Services. Bob moved here from Phoenix. He told me, Almost everyone in Phoenix is using heat pumps for both heating and cooling. They are up to three times more efficient than conventional systems.

He installs heat pump systems regularly. But he cautioned, here, you may need auxiliary heat and heat pumps are electric, so heating bills may be higher. Most people who put them in here do so for cooling because conventional cooling systems require so much maintenance.

Bob believes that, as we transition more from fossil fuels, heat pumps will play a much bigger role and that, eventually, heat pump systems will be automatically placed in new homes.

Joe Hardy runs his heat pump with solar. According to Joe, Efficiency Maine, a statewide program, hopes to help install 100,000 residential heat pumps in the next five years.

If it is time to replace your old furnace, you might consider a heat pump. Heat pumps can play a large role in reducing global emissions as we move from a carbon-intense economy. The bottom line is that, if they work in Maine, they can work even better here in a much warmer climate.

What are heat pumps and why would you want one? - Albuquerque Journal

SIOUX FALLS, S.D. (KELO) As the winter cold snap continues to move through the Midwest, energy cooperatives are urging members to conserve energy.

The Southwest Power Pools (SPP) region is experiencing a generation shortfall due to historic low temperatures along with limited wind resource output from North Dakota down to Arkansas according to a Facebook post by Oahe Electric Cooperative.

Oahe Electric is asking their members to help reduce the energy demand while these frigid temperatures continue by limiting showers, drying clothes, grain handling and drying, baking and other high energy demand activities during this cold snap.

Here are some of the other ways you can conserve energy in your household, according to energy.gov:

The sunlight is a good way to add some extra warmth to your house. Open curtains on south-facing windows during to day to allow sunlight to naturally heat your home. Make sure to close these curtains at night though, to reduce the chill from cold windows.

Using window treatments and coverings can help to improve your energy efficiency and reduce the amount of cold draft throughout your house. Apply a heavy-duty, clear plastic sheet on a frame or tape a clear, plastic film to the inside of your window frames, making sure they are tightly sealed to the frame to reduce infiltration. Install tight-fitting, insulating drapes or shades on windows that continue to feel drafty after weatherizing.

Adjusting your house temperature is an easy way to reduce your energy usage. When you are awake and home, set your thermostat as low as comfortable. When you are asleep or out of the house, turn your thermostat back ten to fifteen degrees for eight hours to save around ten percent on your heating and cooling bills. It is recommended to use a smart or programmable thermostat, which can make it easy to set back your temperature.

If you have a heat pump, maintain a moderate setting or use a programmable thermostat that is designed to be used with heat pumps.

Detect air leaks around the utility cut-throughs for pipes, gaps around chimneys and recessed lights in insulating ceilings and unfinished spaces. You should also add caulk or weather-stripping to seal air leaks around doors and windows.

Make sure you are maintaining your heating systems and schedule service for them. Replace you filter for furnaces and heat pumps once a month, or as need. When using wood-and pellet-burning heaters, make sure to clean the flue vent regularly, along with cleaning the inside of the appliance with a wire brush periodically.

Use can reduce heat loss from your fireplace by keeping the damper closed unless a fire is burning. When you use the fireplace, open dampers in the bottom of the firebox or open the nearest window slightly and close the doors into the room, while lowering the thermostat setting to between 50 and 55 degrees.

If you never use the fireplace, plug and seal the chimney flue to reduce heat loss. If you do use the fireplace, install tempered glass doors and a heat-air exchange system that blows the warmed air back into the room. You can find out more ways to improve fireplace efficiency at energy.gov.

Lower your water heating costs by turning down the water heater temperature to the warm setting (120 degrees F).

Why geothermal is a hot trend in new condos

Building an energy hub on an artificial island

Ontario has fewer Canada jays, likely thanks to climate change

Many condominiums being designed and built right now in Canada are greener than their predecessors not just from the ground up but also deep down. That's because many are turning to fossil fuel-free geothermal or geoexchange technology for their heating and cooling.

While most geothermal systems in the past 40 years have been installed in single-family homes, those in the industry say growth in the market is now driven by condominiums.

"That market is increasing and actually increasing very, very quickly right now," said Stanley Reitsma, president of the Ontario GeothermalAssociation.

Geoexchange is a type of electric heating and cooling that draws heat -- and cooling -- from the ground. (Note: While "geothermal" is the more commonly used term, "geoexchange" is preferred in the industry because it's less likely to be confused with geothermal energy, a different technology for power generation.)

In the past five years, the proportion of condos with this type of electric heating has more than doubled to five per cent in Ontario, Reitsma estimates.

Lloyd Jacobs, general manager of FortisBC Alternative Energy Services, which has installed geothermal systems in dozens of multi-residential buildings in B.C., said there is "a huge demand" for alternative heating systems in large buildings that might have been heated by fossil fuels or baseboard heaters in the past.

Traditionally, a challenge for geothermal energy is the high cost of digging and installing the borefield that is, the liquid-filled underground loops that store and supply the heating and cooling to the system.

But Martin Luymes, vice-president of government relations for the Heating Refrigeration and Air Conditioning Institute of Canada, said those upfront expenses are now offset by savings from things like lower energy and maintenance costs in as little as three to five years for large buildings.

Luymes and Reitsma said there are a few reasons for that and for why condos might want to install geoexchange systems now.

They include:

Green building regulations. Many cities are tightening building standards for efficiency and emissions. For example, the Toronto Green Standard is on track to require new buildings to have close to zero carbon emissions by 2030. Reitsma points out that's not too far away, so many builders want to learn and gain some experience with geoexchange systems now. Similarly, B.C.'s Energy Step Code aims to make all new buildings "net-zero energy ready" by 2032, prompting many condo developers to look for solutions, Jacobs said.

New ways to pay. Builders now have an alternative to paying the upfront infrastructure cost themselves third parties such as FortisBC Alternative Energy Systems and Toronto-based Diverso Energy will build and operate the borefield, then charge a monthly or annual service fee over decades to the condo owners. This way, "the developer gets to offload the risk and the costs associated with geothermal," said Jon Mesquita, Diverso Energy's chief operating officer. In B.C., such utilities are regulated and there are regulatory incentives for signing up with them.

Cheaper cooling and more leasable space. Reitsma said a big difference between condo buildings and smaller buildings is the cooling requirements. Highrises usually require bulky, expensive cooling towers. Because geoexchange systems cool as well as heat, they eliminate the need for cooling towers. That often frees up rooftop space that can be used for penthouse suites, rooftop gardens and other amenities. In multi-use buildings, Jacobs said, heat captured from commercial spaces during cooling can often be used in residential parts of the building.

Interest in and adoption of geoexchange isn't even across the country. Luymes said that's partly because the emissions reductions and therefore the incentive to switch away from heating with fossil fuels are greater in provinces with a clean grid.

He suggested that could change in the future as provincial governments work to decarbonize their electricity grids.

Given the current rock-bottom prices for natural gas, he said, "geoexchange probably won't become a predominant or default technology in our industry ever unless and until supportive policies by the government are implemented."

Last week, Jade Prevost-Manuel wrote about the relative lack of rooftop solar installations in Canada compared to other countries and some of the reasons.

A number of you pointed out that one disincentive in Canada is our electricity bills have a lot of fixed charges, such as distribution and transmission.

Rochelle Jackson wrote: "I've looked into this and if we were to put solar panels on our home and generate our own power, we would still have to pay all those other charges, regardless of how much power we use from the grid. Where is the incentive for homeowners to pay for panels when the bulk of the bill they now pay will still arrive every month?"

There are also some risks with solar in urban areas.Christine Brown wrote: "We have a south-facing roof on our Toronto house, and would gladly install solar panels, except for one problem. In many neighbourhoods in the city, additional floors are constantly being added to existing residential structures. As there are no real restrictions to prevent this, any solar panels we might install could be rendered useless should our neighbour to the south decide to add another story. Urban planning and licensing need to be part of the solar energy strategy."

Some of you also noted that utility-scale solar is much cheaper than rooftop solar.

Robert Macinnes wrote: "Community-built fields of collectors are far more efficient in terms of labour and cost. Each municipality should offer its citizens a chance to buy shares in a large solar array. This has been realized the world over with very satisfactory results."

There's also a radio show! As the rescue in Uttarakhand, India, unfolds after deadly flooding that followed part of a glacier breaking away, scientists are questioning whether climate change was the cause.

Denmark is the largest oil producer in the European Union, but the country plans to phase out fossil fuel extraction by 2050. As part of its transition strategy, the Danish Energy Agency is building an artificial island in the North Sea to gather and distribute green energy from hundreds of offshore wind turbines to countries in Europe. The energy hub, billed as the first of its kind in the world, will be 80 kilometres offshore and cover at least 12 hectares -- the size of nearly 15 Canadian football fields. In the first phase, about 200 wind turbines will generate five gigawatts of energy, or enough to power three million homes. Later, the plan is to expand that to 12 gigawatts, or enough to power 10 million homes. The Danish Energy Agency announced an agreement earlier this month to build the hub as a public-private partnership, although the island itself will be majority-owned by the government. It is scheduled for completion by 2030.

The number of Canada jays in southern Ontario is decreasing because of more frequent freeze-thaw days as a result of climate change, according to recently published research.

The birds' winter food stock was compromised when fall temperatures fluctuated. The food would defrost, grow bacteria and in some cases become inedible.

And that had an effect on the birds' reproduction and population numbers, University of Guelph researchers found in a study recently published in the scientific journal Global Change Biology.

"If your food is being spoiled, you have less food that you can devote to survival and reproduction," said Alex Sutton, who was a PhD student at the University of Guelph when he co-led the study with Ryan Norris, an associate professor in the university's department of integrative biology.

"What seems to be happening is that they need to decide either to survive or to reproduce," said Sutton, now a post-doctoral fellow at Kansas State University.

If the warming pattern in the fall continues to affect reproduction and food supply, the birds could become locally extinct from Algonquin Provincial Park and other southern Ontario ranges, said Sutton.

Canada jays are known for storing their food which can be anything from berries to roadkill meat in nearby trees for the winter.

However, when their food supply degraded with the freeze-thaw weather, the non-migratory birds produced fewer young or hatchlings in poorer condition, Sutton said.

"On average, the number of nestlings has declined over time, or at least in years where there's unfavourable fall conditions," he said.

And that has long-term implications, according to the study with data spanning almost 40 years.

The study looked at the birds in a small part of the park, which is about 280 kilometres northeast of Toronto. However, the Canada jay population that has been studied in the park has ranged from a high of 85 to now between 40 and 50 depending on the year, Sutton said.

"Reproduction was really the key thing that was promoting this decline in Algonquin."

The study used bird population numbers from 1980 to 2018, as well as environment data recorded in Algonquin Provincial Park since 1977 to look at the effects of the fluctuations in temperatures on the bird population and their food supply.

Between 1980 and 1996, which had 10 years of above-average freeze-thaw cycles, the researchers found that the birds' numbers dropped significantly.

Although there were fewer above-average number of freeze-thaw cycles and more breeding success in later years, the birds' numbers never rebounded from "a period of poor environmental conditions that occurred several decades prior," according to the study.

David Bird, a retired professor of wildlife biology at Montreal's McGill University, said the amount of detailed data included in the study is impressive but the results are troubling.

"There's still lots of challenges out there," he said. "Climate change is very worrisome."

Sutton and Bird believe the effects of climate change on the birds' food supply could eventually push the species further north.

The Canada jay can be found in every province and territory, but little is known about the effects of climate change on northern populations.

The study said citizen science databases, like Christmas bird counts, "help to fill this gap in our knowledge and be used to estimate population trends at more northern latitudes." The bird is important to many Canadians, so much so there's a campaign led by Bird and others, like Norris, to name the Canada jay the country's national bird.

Sutton said it's important that we find out more about the Canada jay.

"I think it's really important that we try to understand how this species is actually responding to climate change throughout its entire range," Sutton said.

"This could be a really key point to understanding how future population declines or even changes might occur with changing climate."

Why geothermal is a hot trend in new condos - CBC.ca

The Solar Initiatives (tSI) heat pump subsidy program has proved to be very popular. Over 40 island families have signed up or are ready to learn more. tSI is offering up to $6,000 to offset the cost of a home heat pump installation. That sounds great, but what is a heat pump and how does it work?

Some heat pump facts:

1. A heat pump does not generate heat; rather it moves (pumps) heat from one place to another, for example, from outside to inside your home. Because it does not generate heat, it is much more efficient regarding energy consumption than the old resistance type electrical heating systems.

2. Not surprisingly then, a heat pump system has two major components: the pump, which is located outdoors and an air-handler (which many folk call a minisplit), which is located indoors.

3. The outdoor unit contains a fan which blows air across a coil. Thus heat is transferred to the fluid in the coil. Then a condenser condenses the fluid making it even hotter and pumps it indoors.

4. At that point the indoor unit goes to work blowing air across the now fluid, heated coil and into the rooms of your home.

5. The fluid that conveys the heat is usually a refrigerant, thus necessitating licensed installers.

6. The connection between the outdoor unit and the indoor one are two pipes, usually about one inch in diameter. Often these pipes are hidden in a soffit for aesthetic reasons.

7. Now one of the magical things about this heat pump system is that it can work backwards! When the direction is reversedit takes heat out of your house and pumps it outdoors. So one heat pump system is a heater in the winter and an air conditioner in the summer.

8. And while cooling your house in the summer, it condenses moisture which is typically drained outside via--wait for it--a drainage hose.

9. Now heat pump systems are generally much more efficient than other heating sources. But when the temperature drops down below 10 degrees F, its efficiency declines. For homes with an existing heat source, the Solar Initiative recommends maintaining that system for use on extremely cold days.

10. Although heat pump systems use pre-manufactured components, the exact sizing and configuration needs to be customized to each home and the owners needs and wishes. Once COVID allows us to resume proposals, contracts, and installations we will do so, but it may be some time before we can install systems in every home that wishes one.

Now lets talk about the subsidy. If the equipment you order for the installation at your home equals or exceeds $6,000 you will receive the full subsidy of $6,000. If not, then you will be eligible for a two thirds subsidy of the installation up to a cap of $6,000. However, you must contact me by email at pappas.anthony@gmail.com before March 31st to be on the subsidy list. Subsequently, CoolEnergy will make a proposal which you will be free to accept or reject.

David Reidy of CoolEnergy is our installer. He will be contacting everyone on our list as soon as health and safety factors allow.

Flores Construction: Specialists in Window and Door Installations and Home Renovations Latest News on The News Front - The News Front

KANSAS CITY, MO (KCTV) Having your heating bills rise in this extreme cold is almost unavoidable, but there are ways to lessen that expense.

Two energy efficiency representatives, one from electricity supplier Evergy and one from natural gas supplier Sprire, walked us through a house to highlight those places and solutions.

I like to work from the bottom and go up, said Evergys Nicholas Newport, move the same way the air does, from the basement into the attic.

Newport said one thing to look for is cobwebs.

Wherever you see cobwebs is actually where the air is moving in and out of the house, Newport explained.

If you have an unfinished basement, you might notice them in the corners of the ceiling. That means you should add some insulation on those upper walls

The basement windows we looked at were filled with cobwebs and on closer inspection, there was light coming through gaps in the wooden window frames.

You can feel that air coming in and now you can see the light coming in, Newport said as he held his hand up to the window.

The way to fix that is with window caulk or low expanding foam.

Another culprit is the pipes, starting in the basement then working your way up.

When youre thinking about air infiltration coming into your house, its coming in from outside and going up through your house and to your attic. And the leading spot for that actually is the bathroom. Newport said.

Those gaps should be filled with an expanding foam spray.

Once upstairs, check your doors. Feel for air. Look for light coming through the sides or bottom.

Spire energy efficiency representative Lemartt Holman suggested a test that involves nothing more than a piece of paper.

If I simply open the door and I place a piece of paper in, [then shut the door], and Im able to easily pull it out, thats another opportunity for insulation, Holman described.

Weather stripping, including door sweeps for the base of the door, can accommodate even canted door frames in a house that has settled over many years

When you screw it into your door, you can adjust the angle of it, Newport clarified.

Until you get to the hardware store for that, theres the quick short-term fix of shoving an old towel up against the bottom of the door.

Then there are the windows.

Youve probably heard about the heat-sealed plastic that can seal windows. You might not want it on windows through which youd escape a fire, but there are other windows you might not think about.

Newport noticed a decorative back door with windows.

On your door here, you have a lot of single pane windows. And this actually get very cold, he noted. To touch it felt like reaching into the refrigerator.

Thats why a storm door is important, but its also where that plastic works well.

Newport said the plastic can go on either side of the window. Pick the side less likely to get paint damage, which is a possibility when removed. If you want the edges less visible, consider putting it on the outside.

And you put on this tape right around the edges here, attach the film to it, cut it to size and use a blow dryer to make it tight, he demonstrated.

Another option is heavyweight curtains.

Holman said its also a good idea to double check the windows with sashes to be sure they are securely closed.

One of the ways that youre able to stop airflow from coming into your home is to make sure that your windows are completely locked, pressing completely to the top, and then locking these, it will help to keep the insulation engaged, he said.

Also, be sure your screen is switched to the storm if you have one. It seems obvious, but some of us might have neglected that.

Regular air conditioners are known to be something of an energy hog, drinking power to cool down or heat up your house. So how could a solar air conditioner help?

A solar air conditioner is an air conditioner that runs off of its own dedicated solar panels, rather than one that's hooked up to a regular solar system or the main electricity grid. Effectively, it runs on its own self-contained circuit.

The solar air conditioner consists of three main components:

There are two points at which you may be able to save with a solar air conditioner:

Let's compare the costs of installing a 3.5kW solar air conditioner from Solar ACDC to installing a normal solar system and separate aircon unit.

Solar system + air con

Solar air conditioner

1. Estimates are from this calculator.2. Figure is from this site.

For this comparison, assume that you run your 3.5kW air conditioner for 4 hours every day during all 90 days of summer, keeping it set to 22 degrees Celsius3. Then, if energy from the grid costs 30c/kWh, running an air conditioner on mains power will cost you:

$0.25 (hourly cost of aircon) x 4 (hours per day) x 90 (days in summer) = $90

This means your solar aircon will save you about $90 in running costs annually, if you don't have to rely upon mains power. For larger air conditioners, this might stretch up to $200 annually.

With this in mind, the solar air conditioner will save you about $1,600 on install, and $100 - $200 yearly, for each year you run it. Heating has been excluded from this analysis, since it's most required in late afternoon or evening, after the sun has set and your solar air conditioner is inactive.

3. Calculations are based on this site.

While the solar air conditioner is great in concept, there are a few drawbacks to be aware of compared to just using an air conditioner with a normal solar system:

Solar ACDC claims that some elderly Australians may be able to cover the costs of solar air conditioner installation under the My Aged Care benefits scheme. This scheme is designed to give financial assistance to older Australians who need extra care or services to live safely and independently in their home.

However, Finder's analysis of the requirements for My Aged Care funding suggests that getting coverage for a solar air conditioner is unlikely at best, and you should check the scheme's requirements before making any financial decisions.
