How do I save energy?

There are countless ways to save energy but you will find an overview below and also can see the role of LED lighting technology how LED lighting technology saves energy.

1) Choose a cheap energy supplier

2) Insulate your home

3) Choose a good heating technology

4) Install solar panels or a solar water heater

5) Watch out with sneaking consumption

6) Install LED lighting technology

1) Choose a cheap energy supplier

Now that the energy market has been liberalized, you have the option of choosing a different energy supplier. After last year’s commotion about overpriced energy prices, many suppliers have already revised their prices downwards. Yet there are still important savings to be made in this domain. To choose the most economical energy supplier for you.

When making your choice, also consider the environmental friendliness of your energy supplier.

2) Insulation

Insulation is one of the most important factors with which you can achieve good energy savings. That can be done in various ways; roof insulation, wall insulation, high-efficiency glass, floor insulation, Good roof insulation (12 to 15 cm glass wool) can easily save you 30% on your heating bill. The insulation of walls is also not negligible and also gives you 25% energy savings. The techniques for isolation have evolved enormously.

Moreover, you will still receive interesting premiums if you have the work carried out by a registered contractor

3) Choose a good heating technology

In the past, central heating techniques based on heating oil or gas was used. Because they are quite energy-consuming, many new technologies have been added in recent years that can produce attractive energy savings:

3.1 condensing boilers:

Condensing boilers ensure that an important part of the water vapor in the combustion gases can condense.

This releases more useful heat. In comparison with a low-temperature boiler, an energy saving of +/- 10% can be achieved through the condensing boiler.

3.2 underfloor heating:

Underfloor heating is not only aesthetic but according to enthusiasts also a comfortable system. It results in 100% radiant heat. Moreover, floor heating is also energy efficient. It requires virtually no maintenance and also does not circulate dust in the living room.

The disadvantage is that this is an expensive solution for the renovation market because you have to break up your existing floor.

3.3 wall heating:

You can not only heat your house with pipes in the floor, but pipes in the wall are also possible. The disadvantage is that you have to make openings in the wall when renovating. For the new-build the market there are built-in quick-build sand-lime bricks in which the factory has already made a trench and in which the plastic pipes can be placed.

3.4 air heating:

With air heating, ventilation and heating are integrated into one system. Interesting now that we have to thoroughly insulate our houses. The system is based on constant, imperceptible air circulation throughout the entire building.

3.5 heat pumps: 

There are different types of heat pumps:

a) Geothermal heat pumps

These use the soil as a heat source. Due to the soil temperature in the summer, passive cooling with a geothermal heat pump is possible.

We distinguish 2 types:

Horizontal capture: The garden is the heat source. At a depth of approximately 0.8 to 1.5 m, a pipe network is buried through which a liquid flows that extracts the heat from the ground. Solar radiation and rainfall also increase the heat emission capacity of the soil. The disadvantage is that you need a large area for this and that the investment is quite expensive.     

Vertical capture: Well drilling is done between 50 and 100 m. This system is the most cost-effective but requires a considerable investment. It is not always practically possible to drill deep.

b) Heat pumps with air as a heat source

These are the so-called aerothermal heat pumps. We distinguish between air/air and air/water heat pumps. Both systems use the outside air to extract heat. These heat pumps are cheaper than the geothermal heat pumps but also have a lower efficiency. 

c) Heat pumps with groundwater as a heat source (open systems)

These heat pumps use the groundwater to extract heat. After use, the pumped-up groundwater is discharged again into the same water layer (required by law). This system is not interesting for small assets (individuals).

3.6 Infrared

Heating Infrared heating is pleasant heating. This heating is heating like the sun: when you sit on a terrace in the mountains at -15 ° and the sun shines, you have a pleasant, warm feeling. This heat is feeling the warmth. It also has a good influence on blood flow, which strongly promotes the recovery of muscles and skin cells. These panels also provide relief for asthma patients because there is no air circulation. 

We distinguish 2 types of infrared heating:

a) Short wave

Better is known as terrace heating. Is especially suitable for outdoor heating.

b) Longwave heating: heating in the house or in sheds

The advantage of this heating is that it is easy to install, is inexpensive to purchase and use and, moreover, does not require maintenance.

3.7 pellet stoves

A pellet stove is a small biomass boiler. The fuel is wood pellets made of pressed, pure wood fibers. They are provided with a reservoir in which a complete bag of pellets can be poured. These are fed into the burner by means of a jack. The fan distributes the warm air. With a pellet stove you can quickly save up to 50% on your heating costs, you do not have to install extra pipes and they are odorless and CO2 neutral.

Pellet stoves are very cheap to use and they provide a nice energy saving compared to traditional techniques. They also require very little maintenance.

4) Install solar panels or a solar water heater

Solar panels and solar boilers have been very popular in recent years. Despite the reduction in subsidies for photovoltaic panels (also called PV panels), an investment in this remains attractive. The subsidies for solar boilers were increased in 2012.

A PV panel converts solar energy into electricity. For this photovoltaic cells are mounted on a panel.

These solar cells are made of silicon and under the influence of the light, an electric current flows between the 2 layers of silicone. This direct current must be converted into alternating current by an inverter. The solar panels are usually connected to the grid, ie they draw electricity back into the grid. The electricity supplied by the energy supplier is supplied via the grid manager and the electricity meter is turned back via the production of the solar panels. This reduces the electricity bill. In addition, subsidies are also given for the production of green energy. These are the so-called green power certificates. These have been systematically phased out in recent years because they became too expensive for the network operator. Currently, these certificates are:

Installations up to and including 10 kW

Banding factor 0.23, so 4,348 kWh are required for 1 certificate of 93 euros, or approximately 21 euros per 1,000 kWh

Installations from 10 to 250 kW

Banding factor 0.63, so 1.587 kWh needed for 1 certificate of 93 euros, or approximately 59 euros per 1,000 kWh

Installations from 250 kW to 750 kW

Banding factor 0.49, therefore 2.041 kWh needed for 1 certificate of 93 euros or approximately 46 euros per 1,000 kWh

Solar panels Solar water heaters are also interesting. Solar water heaters are collectors equipped with a sensor that measures the temperature. Once a certain temperature is reached, water flows through it. That water, in turn, warms up the boiler. There are hot water solar boilers (only for heating the domestic hot water) and combi solar boilers (heating support and heating the domestic hot water).

In 2012, the solar boiler premium amounts to 550 euros per m² of collector area, with a maximum of 2,750 euros, which corresponds to an area of 5m², which is more than sufficient to heat a 200-liter vessel. The premium can never exceed 50% of the invoice. For non-residential buildings (both existing buildings and new buildings) the premium is 200 euros per m² with a maximum of 10,000 euros. The premium can never be higher than the invoice amount excluding VAT.

5) Pay attention to stealth consumption

Some devices also use electricity if you are not using the device or if the device appears to be switched off: standby, sneaking or continuous consumption. This dormant consumption can quickly amount to 10% of the total electricity consumption of an average household.

With a number of simple measures, you can already prevent half of this stealth consumption.

Some devices also use electricity if you are not using the device or if the device appears to be switched off: standby, sneaking or continuous consumption. This dormant consumption can quickly add up to an energy saving of 10% of the total annual electricity consumption of an average household.

Also, pay attention to large consumers: Defrost your freezer on a regular basis, so a number of times a year gives a better functioning of your freezer and ensures that you have a saving of +/- € 20 on your energy bill.

With a number of simple measures, you can already prevent half of this stealth consumption.

Use the power button of a device instead of the standby button.

Unplug the power cord from devices that you will not use for a long time.

If you have several devices together, you can put all the plugs in a socket with an on / off switch. Simply switch off the socket after use.

Halogen lamps often have the switch between the lamp and the transformer. The transformer continues to consume power when the lamp is off. If you put the on / off switch between the transformer and the socket, this problem is quickly remedied.

Chargers of a petty thief, toothbrush or mobile phone use electricity even when there is no longer charging. Unplug them from the wall socket when you are not charging or when the device is fully charged.

6) place LED lighting Technology

LED lighting technology has evolved enormously in recent years. Where the lamps used to emit a cold white light, there are now also options for having the warmer LED light. A light color is expressed in Kelvin (K). The higher the Kelvin number, the colder the light. An average light bulb has 2700 Kelvin. LED lighting technology has a choice between warm white (2700-3200K), normal white (4000-4500K) and cold white (6000-6500K). There are currently LED modules on the market that match the warm light color of halogen. CREE LED distinguishes itself from the traditional LED by its brightness and warm light color. There are also LED COB lamps on the market that have very high brightness and a good heat resistance. In this way, they manage to get a lot of light output (lumen) on a small surface.

The big advantage of LED lighting technology is that it consumes considerably less than traditional lamps. An LED lamp will average:

 1/7 use of a halogen lamp, a bar lamp, and an incandescent lamp

1/2 to 1/3 consumption of a fluorescent lamp

1/3 use of a mercury vapor lamp

In addition, LED lighting technology has a great advantage that it lasts much longer than traditional lamps:

LED light: burning hours 50,000.

Light bulb: 1,000 burning hours

Energy-saving lamp: between 8,000 and 15,000 burning hours

Fluorescent tube: 12,000 (T8) or 24,000 (T5) burning hours

Halogen lamp: between 1000 and 5000 burning hours

The prices of LED lamps have also reached an acceptable level.
