The demand for sustainability in modern homes has increased exponentially worldwide, with statistics showing that buildings and construction account for 32% of global energy demand and 34% of energy-related CO2 emissions. Over the past two decades, renewable energy, insulation, and the use of energy-efficient appliances have all played a role in reducing families’ carbon footprints worldwide. Today, smart technology is adding an extra layer of environmental friendliness, enabling homeowners to significantly reduce their household energy and water consumption. It allows them to use fewer resources and reduce their expenditure while remaining safe and comfortable.
Smart Thermostats
Smart thermostats are among the simplest and most effective ways to create a greener home. These devices “learn” household routines, automatically scheduling the home’s heating and cooling needs. They have remote smartphone control, occupancy detection, and weather-responsive adjustment functions, helping owners to adapt their home’s temperature to their precise needs. The benefits of smart thermostats include reduced energy waste, lower heating and cooling costs, and reduced carbon emissions. Research by CNET, for instance, shows that smart thermostats can save an average of 12% to 15% of energy costs per year, even when no other changes are made to a home.
Intelligent Heating Systems
Smart heating controls reflect homeowners’ actual needs, thanks to features such as zoned heating, smart radiator valves, wireless temperature sensors, and occupancy-based heating schedules. They work alongside smart thermostats to make heating systems more precise. While smart thermostats function as “central controllers” for an entire home, other technologies support their functions. For instance, smart radiator valves (TRVs) are installed on individual radiators to automatically control each room’s temperature. Wireless temperature sensors measure the temperature in each room rather than relying on the thermostat’s location. As such, they prevent one room from “misleading” the thermostat regarding the temperature in other rooms. Another technology is occupancy-based heating, which relies on motion sensors or homeowners’ phone locations to determine whether they are at home. Instead of following a predetermined schedule, the heating adjusts based on the homeowners’ actual presence or absence.
Smart Boilers
Smart thermostats are complemented by high-efficiency condensing boilers and smart boiler controls to heat occupied spaces and maintain optimal flow temperatures. Smart boiler controls can also send homeowners service reminders for annual or seasonal maintenance. Smart boiler systems comprise a standard hydronic boiler priced similarly to conventional models. The cost of boiler servicing is also similar, as is that of installation. Typically, the boiler is connected to a smart thermostat (costing between $100 and $300) and (optionally) smart zone valves, additional temperature sensors, or smart radiator valves.
Water-Saving Technology
Average homes can access a wide array of technology that can help them save one of the world’s most precious resources—water. From smart irrigation systems to weather-responsive watering and smart water meters, families can lower their water bills, reduce waste, and protect their properties against expensive water damage. Whole-home leak detection systems are particularly useful because they continuously monitor water pressure, flow rate, and flow duration. These systems employ machine learning algorithms to detect abnormal water behavior. When a problem such as a burst pipe, leaking toilet, or dripping tap is detected, they send smartphone notifications and can automatically shut off the home’s main water supply if necessary. Smart taps, meanwhile, feature touchless infrared sensors, precise temperature control, and automatic shut-off after a preset period, making open-water taps and inadvertent waste a thing of the past.
Smart Lighting
Lighting accounts for up to 15% of households’ electricity consumption, making smart features key for homeowners wishing to reduce their expenses and lower their carbon footprints. Smart LED lighting uses at least 75% less electricity and typically lasts up to 25 times longer than traditional incandescent bulbs, according to the U.S. Department of Energy. Smart bulbs also enhance the comfort factor by enabling precise dimming, color temperature adjustments, and brightness scheduling. Smart lighting systems also typically include occupancy and motion sensors, such as passive infrared (PIR) or microwave motion sensors, which automatically switch the lights on when people enter rooms and off after a predetermined period of inactivity.
Smart technology is a vital aid for homeowners seeking a greener, more affordable lifestyle. Smart thermostats, leak detection systems, and smart lighting are all helping to prevent costly damage, while making home life more comfortable. These technologies are likely to become standard features in the sustainable homes of the future, helping families and nations meet their energy savings goals.
