Can You Enjoy a Warmer Winter Without Increasing Your Energy Use?

Can You Enjoy a Warmer Winter Without Increasing Your Energy Use?

Excessive Energy Consumption in Winter

Home heating costs keep soaring yearly, creating a budget concern among American homeowners. In 2022, the National Energy Assistance Directors Association forecasted each home would pay an average of $1,328 for electricity in the winter of 2023 — a 17% increase from the previous year’s power consumption.

Because people need to stay warm and cozy indoors, the heating system operates for nearly 24 hours. While it’s necessary for survival, homeowners are getting more concerned about the rising energy costs and the impact of constantly running appliances on the environment.

So this brings the question, “Is it possible to keep warm and save on bills?” The answer is a big yes — and there are several options to do so. Here are the workarounds to keep your family warm during winter, minus the skyrocketing bills.

 

Maximize Passive Solar Heating

The easiest way to warm your space is to take advantage of the sun. Doing so doesn’t require any complicated upgrades or installations. All you have to do is open your windows during the day to allow warm air inside and improve circulation.

South-facing windows capture the most heat, so don’t block the sun by placing tall plants directly in front of them. In addition, run your ceiling fan counterclockwise direction — it circulates more warm air by pushing it down.

During the night, close the blinds to trap heat indoors. If you can, invest in thermal-lined curtains. They’re made of several layers of fabric and microfiber that provide a wall between your home and the cold outside air.

 

Insulate Various Home Areas

While it’s ideal to boost insulation from the roof to the foundation, such a move requires a considerable financial investment. The average cost of home insulation is between $3,000 and $10,000 for a 2,000-square-foot home.

 

Windows

If you lack the budget, simply insulating your doors and windows is energy-saving and pocket-friendly. Here are some hacks.

1. Put a Plastic Film or Bubble Wrap Over the Window

You can save up to $20 per window every winter by merely putting a film over your window. If you have five windows, you can put a potential extra $100 toward other expenses.

The process to do this is straightforward. Use tape to secure the plastic to the edge of the window frame. Then, fix the film to the window using a hair dryer.

2. Add Caulk and Weatherstripping

It’s easy to add caulk to your windows. Make sure to cut the tip of the tube to the same size as the gap between the wall and the frame. If you have double-hung windows, weatherstrip them with a V seal.

3. Install Cellular or Honeycomb Shades

This solution may be more expensive than the first two, but they can last for years. Installing honeycomb shades can save you as much as 15% of your yearly HVAC energy use. They just take a bit of measuring and drilling.

 

Doors

Weatherstripped doors can also prevent heat loss, warming up your space during winter. Follow these tips to insulate them.

1. Tighten the Screws and Fittings

Check if the doors’ fittings have come loose, which can happen with time. The door must hang appropriately in the frame.

2. Install Weatherproofing Strips and Seals

Self-adhesive strips are the easiest way to seal gaps between the door and the frame. Meanwhile, you can use a weather seal on the bottom of the door.

3. Hang Heavy Curtains on the Entry Doors

At the back of the entry doors, mount a curtain rail on top to hang thick curtains. You can take this down after winter. Remember to do the same for your garage door using rigid foam boards or other similar materials.

 

Use Smart Thermostats

Modern households are becoming technology-driven. By leveraging advancements, you can control energy use. A great example is a thermostat.

Smart thermostats are designed with sensors, algorithms and machine learning capabilities. When sensors detect someone entering the home, the thermostat automatically turns on and adjusts to the occupants’ optimal cooling or heating temperature.

With use, it can remember the best time to heat the home during winter, saving you 8% on heating and cooling bills or $50 per year. They’re also convenient, as you can control them remotely through an app and voice commands in some models.

 

Use Energy-Saving Mode on Appliances

Your choice of entertainment during winter — which may include a TV, game console or computer — can also add up on your bills. Hook them up to a battery saver or turn on low power mode when operating in this setting is possible. For instance, you can turn your laptop into power saver mode if you only do data entry tasks and don’t need the high-resolution video feature. By implementing this simple change, you can save up to $30 a year on energy bills.

 

Switch to LEDs

Lighting accounts for about 15% of your entire home energy use, which is considerable. Swapping to quality LED fixtures will result in huge savings since they use 75% less energy and last more than 20 times longer than incandescent bulbs.

Besides their low energy consumption, LEDs are more durable than traditional lighting. They’re made of epoxy lenses — not glass — increasing their resistance to breakage. More importantly, their longer life span makes them good for the environment, as they emit less carbon.

 

Layer up Indoors

Another simple, sustainable winter practice is to wear warm clothing at home to reduce the need for heating. Wearing thick winter clothes will preserve your body’s natural heat, decreasing your reliance on electricity to warm up. You’ll have to apply the same hack when sleeping — ensure you cover yourself with a layered blanket.

 

Enjoy a Warmer Winter at No Extra Cost

Power bills shoot up during winter due to the extensive use of the heating system. Fortunately, you can enjoy warm, cozy evenings without increasing your energy use by harnessing the sun’s power to heat your home, insulating any openings where heat can leak and switching to a smart thermostat. Save hundreds of dollars yearly using these simple tips to prepare your home for winter.

Future cities could be 3D printed – using concrete made with recycled glass

Future cities could be 3D printed – using concrete made with recycled glass

3D printed concrete may lead to a shift in architecture and construction. Because it can be used to produce new shapes and forms that current technologies struggle with, it may change the centuries-old processes and procedures that are still used to construct buildings, resulting in lower costs and saved time.

However, concrete has a significant environmental impact. Vast quantities of natural sand are currently used to meet the world’s insatiable appetite for concrete, at great cost to the environment. In general, the construction industry struggles with sustainability. It creates around 35% of all landfill waste globally.

Our new research suggests a way to curb this impact. We have trialled using recycled glass as a component of concrete for 3D printing.

Concrete is made of a mix of cement, water, and aggregates such as sand. We trialled replacing up to 100% of the aggregate in the mix with glass. Simply put, glass is produced from sand, is easy to recycle, and can be used to make concrete without any complex processing.

Demand from the construction industry could also help ensure glass is recycled. In 2018 in the US only a quarter of glass was recycled, with more than half going to landfill.

 

Building better

We used brown soda-lime beverage glass obtained from a local recycling company. The glass bottles were first crushed using a crushing machine and then the crushed pieces were washed, dried, milled, and sieved. The resulting particles were smaller than a millimetre square.

The crushed glass was then used to make concrete in the same way that sand would be. We used this concrete to 3D print wall elements and prefabricated building blocks that could be fitted together to make a whole building.

If used in this way, waste glass can find a new life as part of a construction material.

The presence of glass does not only solve the problem of waste but also contributes to the development of a concrete with superior properties than that containing natural sand.

The thermal conductivity of soda-lime glass – the most common type of glass, which you find in windows and bottles – is more than three times lower than that of quartz aggregate, which is used extensively in concrete. This means that concrete containing recycled glass has better insulation properties. They could substantially decrease the costs required for cooling or heating during summer or winter.

 

Improving sustainability

We also made other changes to the concrete mixture in order to make it more sustainable as a building material, including replacing some of the Portland cement with limestone powder.

Portland cement is a key component of concrete, used to bind the other ingredients together into a mix that will harden. However, the production of ordinary Portland cement leads to the release of significant amounts of carbon dioxide as well as other greenhouse gases. The cement production industry accounts for around 8% of all carbon dioxide emissions in the environment.

Limestone is less hazardous and has less environmental impact during the its production process than Portland cement. It can be used instead of ordinary Portland cement in concrete for 3D printing without a reduction in the quality of the printing mixture.

We also added lightweight fillers, made from tiny hollow thermoplastic spheres, to reduce the density of the concrete. This changed the thermal conductivity of the concrete, reducing it by up to 40% when compared with other concrete used for 3D printing. This further improved the insulation properties of the concrete, and reduced the amount of raw material required.

Using 3D printing technology, we can simply develop a wall structure on a computer, convert it to simple code and send it to a 3D printer to be constructed. 3D printers can operate for 24 hours a day, decrease the amount of waste produced, as well as increase the safety of construction workers.

Our research shows that an ultra-lightweight, well insulated 3D building is possible – something that could be a vital step on our mission towards net zero.
