Almost 50% of all energy needs in a home falls to the heating system. When building sustainably we can achieve bigger savings in all energy types, particularly heat and electricity without lowering our comfort. This is why building sustainably is a key factor in modern housing.
More than ⅕ of electrical energy within a typical household is used for saving food. What we choose as a refrigerator and/or cooler is very important as those types of appliances are running 24 hours a day so how much they use up is immediately reflected in your budget and monthly expenses. In addition to keeping track of how much energy they use, it is also important to note how much volume you actually need, so keep in mind not to buy too small or too big of an appliance. In both freezers and refrigerators temperatures should be set to the optimal level (– 7 °C for refrigerators and – 18 °C for freezers) so that there is no need for extra energy to keep all of the food and beverage items fresh.
For energy rational and efficient use of dishwasher and washing machines it is important that they be optimally filled as well to use proper washing programs. Instead of using an electrical dryer, you can choose to air dry your laundry. The biggest part of electrical energy is used to heat up water and dry out clothes, so when you try to avoid unnecessary extra heating you can save up a lot of energy
In order to reduce energy consumption for electricity, particularly in terms of room cooling, it is advised to maintain an optimal room temperature. Those temperatures depend on the type of the room - for ex. 20 degrees Celsius for living room and classroom , while 24 degrees is recommended for bathrooms.
Fluorescent lightbulbs ("neon tubes") are made from a glass tube lined with phosphor. The tube contains inert gas with a very small amount of mercury. Fluorocompact lightbulbs are bent fluorescent tubes with an inert muffler.
LED lights are now being increasingly used as a substitute for a classic lightbulb, as they use up less energy and last longer than the bulbs that have a tungsten filament.
Day light reduces the need for using artificial lights and by doing so allows for significant energy savings. This is why it’s important to reduce the use of indoor lights and opt for daylight whenever possible. Apart from lowering our electricity bill, daylight is important for our health as well.
There are a lot of reasons why we should use sun energy as much as possible.
Kitchen has a lot of appliances that need a lot of energy and all of them are used daily. Apart from the dishwasher and the refrigerator, these large energy users also include the stove and kitchen hood. This is why we need to be mindful when purchasing those elements as by selecting appliances with a higher energy class, we can save a lot more.
One of the ways to use the stove rationally is to select a heating area that matches the size of the pot used – it shouldn't be larger, or smaller than the pot bottom. By doing so energy isn’t radiated around nor does it take longer to cook.
