With short, cold winter days comes an all too familiar yearly ritual: We turn our heating up, to which the energy bills quickly follow. Did you know that space heating alone accounts for an average of 64.4% of energy consumption in European households (Source: Eurostat)?

Many homeowners try to save by manually turning down the thermostat or simply braving the cold in extra layers, but this often comes at the cost of daily comfort. With a KNX smart home, you don’t have to choose between warmth and sustainability. By shifting from passive energy use to a proactive, intelligent automation system, you can automatically reduce waste while enjoying a perfectly heated home.

Comfort per room: only consume heat where you live

In most traditional homes, heating is an all-or-nothing affair. A single thermostat in the living room often dictates the temperature for the entire house, meaning you end up heating empty hallways or guest rooms unnecessarily. KNX changes this through zoned heating.

  • Customized schedules: Set independent heating curves for every room. Ensure the bathroom is warm for your morning routine, while bedrooms stay at a crisp, energy-efficient temperature during the day.

Smart shading: your home’s natural thermal shield

A truly smart home doesn't just react to the cold; it anticipates outdoor conditions. By integrating a KNX Weather Station on your roof or facade, your home becomes weather-aware, turning your windows into active energy managers rather than just glass panes.

Harnessing free solar heat

Even on a freezing winter day, the sun provides significant thermal energy. Your KNX home can coordinate your blinds and heating to work in perfect harmony:

  • The solar boost: When the weather station detects bright winter sun, KNX automatically opens your blinds or curtains. Allowing solar radiation to naturally warm your floors and furniture, reducing the workload on your heating system.
  • Preventing the "overshoot": Because KNX is an integrated system, your heating system recognises solar contribution. It will preemptively throttle back the radiators or floor heating to ensure the room stays at your preferred temperature, preventing that uncomfortable (and wasteful) midday heat spike.

Creating an insulating barrier

The moment the sun sets, your windows become one of the biggest source of heat loss. KNX steps in to prevent the chill before it starts:

As dusk falls, your shutters or heavy curtains close automatically. This creates an extra layer of trapped air between the glass and the shutter, acting as a powerful thermal buffer that keeps the precious warmth inside.

Knowledge is power: trust in real-time energy monitoring

Many homeowners are surprised by their energy consumption when their final bill arrives. It’s difficult to change habits when you don’t know where the waste is happening. With KNX energy meters and monitoring tools, you gain real-time insights right at your fingertips.

Identify and eliminate energy leaks by tracking exactly how much electricity your heating pumps, appliances, and lighting are consuming at any given moment.

  • Data-driven changes: Instead of guessing, you can see the direct impact of your actions. Watch your consumption drop in real-time as you switch to night mode or as your smart shading takes over.

  • Cost forecasting: Advanced monitoring tools support tariff input, letting you forecast energy costs before the bill arrives. This transparency is the first step toward a truly high-performance, cost-effective home.

Effortless savings with automated scenes

Sustainable living becomes much easier when it requires zero effort. Smart scenes allow you to group multiple actions into a single command, ensuring your home always performs at peak efficiency based on your daily routine.

The "leave home" scene: We’ve all had that nagging feeling after leaving: "Did I turn off the kitchen light?" With one click, your KNX smart home can execute a ‘master off’ command. Every light is turned off, and non-essential standby devices, like your coffee machine, are disconnected to stop phantom energy drain. Simultaneously, your heating enters energy-saving mode, ensuring you don’t waste money heating an empty house.

Night mode: As you settle in, your home should transition with you. When activated, night mode automatically lowers your shutters to create an extra air pocket that prevents heat loss through the glass. While the living area temperature is reduced to save energy, the system maintains a perfect, healthy climate in the bedrooms for a restful night.

Start your sustainable winter journey today
