In fact, warming our homes is one of the big items on the climate accounts. An average Danish residence emits an average of 1.3 tonnes of CO2 every year.
However, that number can be significantly reduced if, for example, you get new windows or insulate the walls.
Here are a few tips on how to optimize your home’s energy:
Much of the heat dissipates through poorly insulated attics, especially in older homes. If you are a little handy, you can even insulate the ceiling without the hassle. If, for example, 100 millimetres of insulation is already in place, it will cost DKK 15-20,000 for materials for 100 square meters of the ceiling, which pays for itself after 5-7 years.
Another easy and effective approach is to get insulated wall insulation. Older houses often have 70-100 millimeters of air between the front brick and the rear brick. For 90-100 kroner per square meters you can get the space isolated, which pays for itself home after 5-7 years.
You can save up to 10 percent on the heating bill if you replace old thermostats with new ones. Typically, you will be able to save around DKK 100 per year. thermostat that you replace. They cost between 200-500 kroner and it is easy to replace them. It will pay home again in 2-5 years.
Another option is to get a so-called “smart thermostat” where you can control the heat consumption when you are at home when you sleep, etc. In this way, you do not use unnecessary amounts of heat when you do not need it.
Doors and windows
Window sealing strips can become less dense over the years and it is actually both easy and cheap to replace them. Sealing strips cost 10-50 kr. meters. The real effect on the heating bill is difficult to give an example of, as it depends on how leaky the sealing strips are.
Much of the heat can be wasted energy if pipes in e.g. basement or attic are not insulated. There is at least DKK 200 to be collected per year. meters of heat-conducting pipe you insulate. It can be purchased for just £ 10-40. per. meters, so it can pay back pretty quickly.
If you have older windows, it may sometimes be worthwhile to replace the panes or install the panes. Replacement for energy glazing costs approx. 2,000 kr. square meters, while new windows cost about DKK 8,000. Depending on the type, mounting windows can be mounted for DKK 500-2,000.
Another possible improvement, of a slightly larger nature, is to replace the heating installations. It is e.g. much heavier on the CO2 accounts to use an old oil stove, rather than gas or district heating plants. In addition, there are of course also options such as solar, geothermal or wind energy which can provide the house with cheaper and more sustainable energy.
It is not always that we are the master of these things. If you live, for example. for rent, it is often not an opportunity to make the proposed improvements. And that being said, it will still leave an impression on the climate that you are heating up your home, regardless of whether all these parameters are well controlled. Here it may be an opportunity to offset CO2 for the imprint it is not possible for one to reduce.
