An thrifty house in energy, this is what the construction of a new house. Especially since the latter are subject to the environmental regulations 2020 ou RE2020. A new house RE2020 thus consumes much less energy for its heating than an old house. better designed, bioclimatic, better insulated and equipped withhigh-performance equipment these houses drastically reduce bills. However, it is always possible to do better. Here are 12 tips for reduce your energy bill in his new house.
Economical house: combine sobriety and comfort
Reduce by 10% the energy consumption the French ! It's possible. The government asks everyone to make an effort to reduce national consumption by 10%. To deal with the current crisis, which, from the environment to geopolitics via the economy, is raging on all fronts, we must relearn sobriety. Simple, quick and low-cost actions can limit the risk of shortages and soaring bills. Here are several actions recommended by the association Negawatt in residential buildings.
Lower the heating without losing comfort
If the recommended temperature in a dwelling is 19°C, in practice, few people do not raise the thermometer. Yet it is one of the main levers for reducing consumption. Nothing could be simpler in recent houses. The new constructions, especially at Sic houses, are often equipped with a regulation and a programming. Thanks to thermostatic valves and thermostats, regulation maintains the temperature of a room or dwelling at a chosen temperature. Very simple to install and inexpensive, this equipment also guarantees the comfort of the inhabitants by avoiding sudden variations in temperature.
23,5 TWh could be saved if everyone followed this instruction. These additional degrees represent 13% of heating consumption in the house.
Adapt your clothes indoors
Wearing warm clothes in the middle of winter, even indoors, is a matter of common sense. However, there is no question of taking out the down jacket. In a new house, lowering the temperatures inside the dwelling is not a constraint. Very airtight, these thrifty houses offer a felt temperature stronger than a badly insulated old house.
5 GWh can be saved thanks to this measure. Indeed, lowering temperatures by an additional 900°C saves 1% of heating consumption.
Lower the temperature at night
Reduce the temperature at night, it is economical and it also allows you to sleep better. Nothing could be simpler when you are equipped with a heating schedule. Communicating with the boiler or pompe à chaleur and the different heat emitters (heating floor, radiators, etc.), this equipment makes it possible to define life scenarios. Lower the heating at night when you sleep, and raise it in the early morning for example. A good way to save without feeling the slightest discomfort.
3 GWh is the mobilized deposit linked to this measure.
Indispensable programming in new construction
Lower the temperature instructions 2°C during the day when the house is empty, turning off the heating only in unoccupied rooms, such as the bedrooms during the day... These are measures that save a lot of money and make the thrifty house. In practice, it is a difficult routine to implement. Especially since it is never pleasant to return to cold accommodation at night. Again, a programming makes it possible to put this instruction into practice without constraint, and without losing comfort. Some systems are smart and even memorize your habits. THE home automation box allow you to communicate on site or remotely with your heating thanks to a simple app.
These measures can represent 4 to 5% of the heating consumptione. Here again, to achieve the 10% reduction in consumption within two years set by the government, it is enough for only 5 to 7% of households to do so.
House that saves domestic hot water: limit the flow
Foaming the water out of the faucet does not lower the pressure or the comfort. On the other hand, the water consumption and moreover hot water is divided which makes serious energy savings. Hand showers, bathroom or kitchen faucets, these flow limiters ou foamers arise everywhere. They now equip most of the new housing. The cost of these systems is very low since it represents between 5 and 45€.
If everyone installed this equipment at home, a 25% reduction in hot water draws on treated taps and showers would be possible!
Insulate hot water tank and circuit
Do not waste energy, such is the rule. To keep the heat in domestic hot water tank, it is better that the latter is isolated. Heat losses will thus be limited. A storage temperature of only 50 or 55°C can then be considered.
Similarly, the pipes between the cumulus, the heat pump or the boiler and the taps or the shower must be insulated to avoid heat losses which can represent, in old buildings, up to 7% of the energy consumption linked to the production of domestic hot water in residential buildings.
Save on cooking in a thrifty home
Another place of expenditure: the kitchen, because the equipment of electric cooking are very energy intensive. Limit the use of hotplates and electric oven is not easy. Nevertheless, there are some good practices: prefer fresh products to frozen products, stop the oven before the end of cooking, cover pans and saucepans, and choose equipment labeled A+.
All these measures could eliminate 10% of energy consumption linked to cooking in the residential sector.
Other solutions exist such as solar cooking For example. Entirely free, it nevertheless asks to adapt its way of life.
Watch out for devices on standby
The watches can represent 15% of the average electricity consumption of a dwelling ((excluding electric heating). Computers, television, microwave, washing machine, many appliances remain in operation when not in use. We sometimes wonder about the usefulness of having the time on their microwave or to be able to switch on their television by pressing the remote control rather than the on button.The solution?multi-sockets with switch and/or programmers.
This deposit could represent a 14% reduction in household electrical consumption.
Take control of your internet boxes
In the same way, the boxes consume energy continuously. However, it is possible to do without it when the house is empty or asleep. For a thrifty house, a power strip with switch allows you to turn off the whole thing without thinking about it.
This consumption is anything but insignificant since it could represent a 3 to 4% reduction in household electrical consumption.
Washing machines: when and how?
Savings are also made on how to use its appliances, washing in particular. According to the contract that we signed with our electricity supplier, it may thus be more advantageous to start the cycles outside of consumption peaks. Finally, it is always useful to read the manual to better understand the operation of its equipment.
Choosing more sober programs, better filling the appliances and limiting the dryers could thus represent a 3 to 4% reduction in household electrical consumption.
Connect your home
One of the great advantages of connected homes it's the energy savings. Regulation et heating programming, but also water heater can save you a lot of energy. Reduce your heating bills, it also goes through optimize solar gain. Automation and programming solutions can be implemented on the roller shutters as flappers. A great way to optimize solar gains summer, like winter. Without thinking about it, a home automation solution will open the shutters at the right time to bring in the sun or, on the contrary, to protect against it. also an ideal solution for maintaining the comfort of your new house in every season.
