Tips, not only for the professionals
With 40% of the global energy consumption (which is more than the industry and transportation sector), accounting for 21% of the worldwide CO2 production, buildings have a high potential for saving energy and the environment. First steps are already visible, e.g. by the step-by-step replacing of heat-creating lightbulbs by efficient LEDs and better insulation of walls and windows. Nevertheless, buildings still have a huge potential for saving energy on a massive scale. The following points will explain, how up to 60% of energy can be saved by adding simple features to a building.

1. Energy Efficient Devices
Although it might seem obvious, older devices are commonly used in households, such as the old washing machine, which was given by the mother to the soon-to-be college student, or the fridge with the hardly used ice compartment, which served perfectly for decades but now eats electricity. Although it is most likely not a secret to the users that these devices consume more energy than new energy efficient devices, but sadly, the initial investment of changing to an energy efficient model often leads to keeping the existing equipment.
What is often not taken into account is the fact that the initial investment can be recovered quickly; an initial investment of say, $1,000 for a new boiler could be recovered in as little as 3 years through lower energy cost savings. You not only enjoy a better piece of equipment, but also lower monthly outgoings.
Daylight - Natural and healthy lighting
2. Stronger usage of daylight and less usage of artificial light
Besides the many healthy aspects of daylight, the following is certain: daylight is free and daylight is available throughout the day (as long as you do not live in the area of polar bears and penguins at the wrong time of the year). Obviously, we can already fulfil our needs with ‘better’ light from the sun by opening blinds and shutters, instead of switching on a light, which would illuminate with 100% power.
It goes without saying that daylight harvesting does not always work, for example on a cloudy, rainy day, or simply during night. However, the daylight, which can be harvested throughout the day can be supported by the usage of simple dimmers. The purpose of dimming lights is therefore not only to create a cozy mood, but can also support the currently existing daylight in order to continue with working or with day-to-day activities. By using dimmed light, the lighting would not have to illuminate with a strength of 100%, but e.g. only by 20%. Just by adding the 20% of lighting, the lux level in the used room will be high enough for a proper well-being whilst using the benefits of daylight provided by the sun. Saving energy and enjoying health benefits.
