Switzerland Tightens Energy Requirements in 2026
Starting in 2026, Switzerland will implement a new law on building energy efficiency. This regulation aims to reduce energy consumption and encourage the use of more sustainable technologies. For building owners and managers, this means an increased need to monitor and optimize heating and lighting systems.
Why is this law important?
The new Swiss law on building energy efficiency aims to reduce the environmental impact of homes and infrastructure. It imposes strict standards for energy consumption, particularly concerning heating and lighting. Buildings will need to be equipped with systems that effectively measure and control these two major energy expenses.
How casasmooth can help you
At casasmooth, we offer innovative solutions to meet these new requirements. Our platform allows you to monitor and optimize energy consumption simply and effectively.
Heating monitoring
With casasmooth, you can monitor and adjust your heating system in real time. Our system integrates temperature sensors and smart thermostats that adapt to your needs and schedule. You can use window-opening sensors, for example, to pause heating when a window is open. This way, you can reduce energy consumption without compromising comfort.
Lighting management
casasmooth also provides solutions to optimize your home's lighting. Our system allows you to adjust light intensity and color based on the time of day, ambient brightness, and room occupancy. This not only reduces energy consumption but also creates a pleasant atmosphere tailored to each moment.
Detailed electricity consumption tracking
casasmooth measures your consumption at the electrical panel level and for each circuit using three-phase modules (e.g., Shelly Pro 3EM), as well as for each device via smart plugs with built-in metering. You can precisely identify the biggest consumers (space heaters, appliances, IT equipment, standby modes) and take action where it matters most. Historical data is stored locally with minute-level precision, without relying on external cloud services.
Control of energy-intensive appliances
Washing machines, dryers, dishwashers, water heaters, pool pumps, office equipment: all these can be scheduled and triggered at the right time. casasmooth automates their operation based on occupancy, time, available local energy, and real-time electricity prices to avoid unnecessary consumption and shift flexible loads to more favorable periods.
Automatic adaptation during energy shortages
casasmooth automatically adjusts your home when available energy decreases: reducing non-priority loads, putting non-essential devices on standby, maintaining critical functions. This works both during power outages and supply shortages, with no internet dependency.
Control of AC units and heat pumps
Via connected infrared controllers (e.g., NodOn AC Zigbee) or compatible interfaces, casasmooth can control your AC or air-to-air heat pump without replacing it, adjusting settings room by room based on your habits, occupancy, and outdoor temperature.
SmartGridReady compatibility
casasmooth complies with the Swiss SmartGridReady standard, which defines harmonized communication between buildings, equipment (PV, batteries, heat pumps, charging stations), and grid operators. Your home becomes a node capable of receiving tariff and control signals from the utility and automatically regulating equipment accordingly — without relying on closed proprietary platforms.
Real-time energy pricing
casasmooth retrieves hourly electricity tariffs (regulated or dynamic depending on your provider and the ongoing LApEl revision) and uses them directly in automations. A laundry cycle started at 1 PM instead of 7 PM, an EV charge shifted to off-peak hours, a water heater activated during the lowest tariff window: decisions are no longer based on "fixed off-peak hours" but on CHF per kWh when it counts.
Calculation of actual energy mix costs
At any time, casasmooth calculates the cost and footprint of the energy mix actually consumed by your home: self-produced share (free), battery share (deferred), grid share (at current hourly rates). You see not just how much you consume, but what each kWh truly costs — radically changing daily choices and allowing realistic ROI assessment for each device.
Integration of EV charging, at home and on the go
At home, casasmooth manages your charging station based on PV surplus, home battery status, or hourly rates. On the go, public charging sessions are synced via your vehicle and consolidated in the same dashboard: you get complete EV consumption history — kWh, cost, location — without juggling multiple apps.
Energy flow coordination
The entire system — PV production, home battery, EV, heat pump, water heater, major appliances, public grid — is coordinated by casasmooth to continuously optimize three simultaneous goals: maximize self-consumption, minimize bills (using hourly tariffs), and preserve comfort. This building energy management function becomes relevant for individual homes thanks to dynamic pricing and SmartGridReady.
Optimization advice based on your data (opt-in)
If enabled, casasmooth analyzes your consumption data, environmental parameters (temperature, humidity, air quality, sunlight), and device behavior to provide concrete optimization tips: heating regulation adjustments, malfunctioning devices, abnormal standby consumption, underutilized tariff windows, oversized battery capacity. This analysis uses external services, and data is anonymized before leaving your home — no personal identifiers, addresses, or traceable information is shared. The feature is disabled by default and can be toggled anytime.
A local, privacy-respecting approach
Our platform is designed to operate locally without permanent cloud connectivity, keeping your data secure at home. It also integrates with various open protocols for broad compatibility with existing devices.
In conclusion
With Switzerland's new building energy efficiency law, adopting suitable technologies is essential. casasmooth provides smart, modular solutions to optimize energy use while preserving comfort and privacy. Discover our offerings at casasmooth.com and prepare your home for 2026.
