Why low-energy homes still need intelligent control
Passivhaus and low-energy homes are designed to achieve exceptional comfort while using very little energy. But good building performance does not stop with insulation, airtightness and ventilation. How the finished home responds to changing conditions matters too.
A well-designed low-energy home works hard before any technology is added. High levels of insulation reduce heat loss. Airtight construction limits unwanted draughts. Mechanical ventilation maintains fresh air while recovering heat that would otherwise be lost. But once people move in, the building becomes a more dynamic environment. Sunlight changes throughout the day. Rooms are occupied at different times. Heating demand varies. Blinds are opened and closed. Lighting use changes with both daylight and routine. Intelligent control can help the home respond.
Making better use of the building
Solar gain is a good example. During colder months, sunlight can provide useful warmth and reduce the amount of heating required. During warmer periods, the same solar gain can contribute to overheating. Automated shading can respond to changing conditions rather than relying on someone remembering to lower a blind at the right moment. The same principle applies elsewhere. Heating can be controlled room by room, while lighting can respond to occupancy and available daylight. The aim is not to add technology for its own sake. It is to help the home perform as intended while remaining comfortable and straightforward to live in.
Bringing lighting, heating and shading together
With SMARTliving from Theben, lighting, heating and shading can be managed through one integrated system.
For a Passivhaus or low-energy self-build, that could include:
- Coordinated control of lighting, heating and shading
- Automated blinds to help manage unwanted solar gain
- Individual room control suited to low heating demand
- Lighting that switches off when rooms are not being used
- Familiar wall switches alongside app and voice control
- Operation without relying on a permanent cloud connection
- The flexibility to adapt or expand the system over time
SMARTliving is based on KNX, the open international standard for home and building automation. Rather than relying on a collection of separate smart devices, the system can be planned alongside the electrical and mechanical services from the outset. It also provides a flexible foundation that can evolve as requirements change.
Simple to live with, planned from the start
A smart system should make a low-energy home easier to live with, not more complicated. Day-to-day control can remain as familiar as using a wall switch, while functions such as heating and shading can respond automatically in the background. The important part is planning those controls early. Smart technology does not make a building Passivhaus. The building fabric, orientation, airtightness, ventilation strategy and energy modelling remain fundamental. But integrating lighting, heating and shading alongside those decisions can help the finished home operate more comfortably and efficiently. It also avoids leaving important control decisions until later, when changes may be more difficult or expensive.
