Isn't the warmth of sunlight on our skin delightful? As humans, we simply can’t do without that essential vitamin D. It regulates our hormones, which in turn influence our sleep and our mood. Did you know it also helps our brains and eyes function at their best?
But sunlight also has another effect on our daily lives. Because we now spend up to 90% of our time indoors, it’s precisely there that sunlight can sometimes have a less pleasant impact.
Our homes are becoming increasingly well insulated. That’s great in winter, helping to keep the heat inside. But in summer, it’s a different story. Temperatures can rise quickly, and overheating becomes a real risk.
This isn’t only true for modern homes. Older houses with little or moderate insulation can face the same problem. The result can be a range of issues, from fatigue to health complaints, and from sleepless nights to a loss of concentration.
But it doesn’t have to come to that.
Meet dynamic solar shading: a smart system that responds to sunlight and temperature. Think of your external and internal solar shading, such as screens, roller shutters or blinds, that open and close at exactly the right moment. This allows you to regulate, with remarkable precision, how much light and heat enter your home.
With smart solar shading, you keep your home cool on warm days and comfortably warm in winter. No harsh sunlight on your screen, no sleepless nights caused by heat. Instead, calm, balance and a pleasant atmosphere, day after day.
In summer you keep the heat outside, in winter you let the sun’s warmth in. Smart solar shading thinks along with you, and quietly reduces the need for air conditioning, fans and heating.
It works automatically and ensures your home adapts to the climate. Summers are becoming hotter and energy more expensive. By smart use of sunlight, you contribute to a sustainable future and increase your home value.
When indoor temperatures rise above 27°C, overheating occurs. Sleeping becomes more difficult, your concentration drops and your sense of comfort at home quickly decreases.
Current energy prices continue to fluctuate. So how can we achieve greater certainty, comfort and a lower energy bill under these conditions? The answer is simple: let your smart solar shading help you reduce heating or cooling, without sacrificing convenience.
Dynamic solar shading consists of three components:
The result, cool in summer, warm in winter.
If you want to achieve the maximum benefit from dynamic solar shading, it starts with the type of solar shading installed in your home.
Electric roller shutters are the most effective, followed by (metallised) screens.
Curtains can also contribute to the result, provided they have a metallised layer. Window coverings can help as well, but they are less effective.
The TaHoma switch is the central hub for the automatic control of your external and internal solar shading. With the accompanying app, you can set up and adjust scenarios as you wish. These can be based on programmed schedules or automated through sensors.
The TaHoma switch and the sensors also allow your solar shading to operate when you are not at home. At any moment, you can check the situation in your home directly through the app.
Sensors continuously measure sunlight intensity and temperature. Your solar shading opens and closes automatically, so there is no chance of forgetting.
The sensors operate wirelessly and, in principle, each façade requires its own sensor.
to ask when you consider to purchase dynamic solar shading
Exterior blinds score better than indoor blinds to keep the heat out because it reflects solar radiation before the window heats up. Roller shutters are the most effective because they insulate well, they close the window completely and do not let light through unless you put it on the ventilation position. Screens are also effective in sun protection, especially if you use a dark fabric with a small openness factor (2%).
Alternatively, interior blinds can be used with metallized fabric. There is then a metallised coating on the outside of the roller gorin or pleated that reflects the sunlight. However, window coverings are always less effective than outdoor blinds. Curtains have the same effect as other interior blinds. When using curtains then black-out fabric is most effective. When closed they, to a large extent, will trap the suns heat but only when it has already entered the room.
The openness factor indicates how much daylight and visibility a fabric lets through. A low factor (2–3%) means a more densely woven fabric that lets in less light and heat, essential for preventing overheating. A higher factor (4–5%) offers more daylight but less protection.
For optimal comfort, choose tailor-made sun protection per façade:
Interior sun protection only stops the sun's rays after the glass has already warmed up. As a result, a large part of the heat still comes in. That is why indoor sun protection achieves a maximum of 70–80% of the effect of external sun protection
Always choose metallized fabric, which has a reflective metal layer on the window side. This ensures maximum reflection of solar radiation. The three best options:
Metallized roller blinds.
Metallized pleated blinds.
Duo roller blinds with metallized fabric. A low openness factor (2–3%) is essential; Color is less important than the metal layer present
Why is only dynamic shading really effective for thermal comfort?
Only automatic blinds react directly to sun and temperature and thus prevent your room from heating up. Manual systems are often operated too late and therefore offer insufficient protection. Dynamic sun protection provides stable comfort, without you having to think about it.
