YIT and energy efficiency

One of the main trends in residential construction today is energy efficiency. However, this is not just limited to correctly chosen insulation, proper doors and windows, or solar batteries. How energy efficiently you use your house and its equipment is also important. The synergy between these two fields is important.

 

Energy efficiency

The first and most important step is choosing an energy-efficient dwelling. When designing the project and subsequently implementing it, the question is always how to achieve rational energy efficiency that is proportionate to the costs.

Energy labelling

A system of energy efficiency cards for structures has been or is being created in all European countries, with energy labelling that indicates the level of energy efficiency. We are all familiar with the energy labelling on electrical home appliances, such as refrigerators, washing machines and dishwashers. Energy labelling provides a clear and general picture of a building’s energy efficiency expressed in absolute numbers, based on which it is easy to calculate the annual energy savings. This labelling also provides a clear graphic view of how a particular solution compares to the required minimum values in the country.

Standards

Several factors need to be considered when assessing the energy efficiency of a building. These include the means for providing heat and hot water. Each country has regulations for assessing the energy efficiency of buildings. This are based not only on the different climatic conditions, but also on the economic and technical standards that apply in the area.

   

Easy ways to save energy at home

One way is to choose a suitable energy-efficient dwelling, and another is to make use of the dwelling’s entire potential. There are many ways how to save energy at home without having to give up anything.

You are probably already aware that various energy consumers consume energy at various rates, and you should pay attention to energy labelling. But do you know how much the equipment that you leave on standby for a long time costs you annually? Or how much more effectively refrigerators and freezers work if you vacuum clean their cooling elements at least once a year? There are an endless number of ways to save energy at home, but the first and most important step is to always choose the right project!

Some tips on how to easily save energy at home

  •  

    Do not open the refrigerator door unnecessarily. Warm air moves into the refrigerator when the door is opened, and this must then be cooled. The humidity in the refrigerator also increases, and this creates ice that in turn increases energy consumption. Another unwelcome result is food spoilage and increased bacteria.

     

    Use special heating appliances (electric kettles, coffeemakers, toasters) in the kitchen. This saves time and energy.

     

  •  

    Use as little water as possible when boiling food. For example, 1/8 litre of water is sufficient for boiling potatoes or vegetables. For long-term boiling use a pressure cooker that can help to save up to 40% of consumed electricity and 30% of time.

     

    At least once a year, thoroughly vacuum the dust off the refrigerator’s cooling element (but sure to be careful) – the dust inhibits the cooling process and thus increased energy consumption.

  •  

    Do not put uncovered liquids (soups, drinks, water for making ice cubes) in the refrigerator, because cold liquids vaporise and create ice.

     

    Do not place the refrigerator or freezer too close to the wall, since a resulting insufficient supply of air may increase energy consumption by up to 10%.

  •  

    Every time you open the oven door to check on the food, the temperature drops by 20 to 40 degrees. If your oven does not have a glass door, use a kitchen timer.

     

    Use suitable pots for cooking food – flat-bottom pots can save up to 30% of energy.
