Since the war in Ukraine, many of us have started paying more attention to our smart meter displays, which previously were often neglected after a few weeks on the countertop. Home energy management systems now play a crucial role in helping homeowners monitor and manage their energy consumption in real-time. These systems provide valuable insights into cost and usage patterns, and they suggest simple changes and optimisations to reduce expenses and minimise environmental impact.
Previously, installing such a system was prohibitively expensive, requiring a combination of Crestron or Control4 and a variety of electronic components and digital gadgets to function properly. However, solutions from companies like Gira, innovative interfaces such as Turn, and consumer friendly offerings from companies like TADO have made these systems much more accessible and affordable.
Most of the opportunity, though, comes from the change in the greater energy landscape. We’re moving to a world of ‘Hybrid Homes’, with elements of microgeneration (photovoltaic on your roof, ground source heat pumps, etc.), local storage (batteries in the home, car), increased consumption (electric cars, electric boilers) and smart demand/ response management software so you can use power efficiently and sell what you don’t need back to the grid (aggregated with neighbours, this is sometimes referred to as a ‘virtual power plant’). This shift necessitates immediate actions for homeowners, including preparations for electric vehicle charging infrastructure, adoption of in-home storage solutions, and phasing out gas-based systems.
WHAT IS A HYBRID HOME?
Hybrid homes integrate both passive and active energy systems to optimise energy performance and energy management. They combine the passive design strategies of Passivhaus with active technologies like solar panels and heat pumps to further reduce energy consumption and enhance sustainability. Together, these approaches contribute to the development of homes that are not only energy-efficient but also comfortable and environmentally friendly.
WHAT IS PASSIVHAUS?
Passivhaus is a rigorous standard for energy-efficient buildings. It focuses on reducing the energy needed for heating and cooling by up to 90% compared to conventional buildings. This is achieved through several key principles, including super insulation, stringent airtightness, minimal thermal bridging, and the optimisation of passive solar gain. Passivhaus buildings also use mechanical ventilation systems with heat recovery to maintain a comfortable indoor climate with minimal energy use. The design emphasises a whole-building approach, ensuring high-quality construction and performance through exacting quality assurance processes
If we are to meet the UK’s zero carbon target, all new buildings should be built to the Passivhaus standard. Alongside the architectural design and lower embodied carbon materials, the integrated technology is key to managing the energy efficiency of the building. KNX is the system to manage all of the technology within your home and meet Passivhaus standards.
