More and more people are interested Achieve energy efficiency at home, either because of the savings an efficient home offers (in addition to paying up to 20% less than the IBI) or because of growing environmental awareness trying to limit the footprint on the environment. However, in Spain there are still millions of houses of a certain age that are very energy intensive. If this is the case for you, there are a number of things you can do to resolve it. A good strategy is to take advantage of any reform you consider Introduction of improvements aimed at energetic rehabilitation.
CALCULATE HOW MUCH IT COSTS TO IMPROVE YOUR HOME’S ENERGY EFFICIENCY
Many factors influence energy efficiency
What is energy efficiency?
IN energetic efficiency It is a concept that shows how much energy a house has to use to achieve the comfort that its tenants need. This is calculated through measurement energy consumed and further Emissions of CO2 it is produced year-round from the household and is given in kWh / m² and kg CO2 / m² per year. Depending on the results, the house receives an energy rating that can range from A (most efficient) to G (least efficient).
The level of energy efficiency and the investments required to achieve it
If you take into account that a house with energy efficiency class A consumes 90% less energy than a house with energy efficiency class G, we can get an idea of how important it is to achieve maximum energy efficiency. However, this is a complex concept, influenced by many factors which we need to work separately to improve the overall rating and which we will comment on below.
Passive house standards are one way to achieve energy efficiency
Factors to consider when determining the energy efficiency class
Limit energy requirements
This will vary depending on the region you live in. Aspects to be considered are:
- Look for heating or cooling depending on the area.
- Quality of the insulation materials
- Quality of the housing, for example the type of glass or doors used.
Execution of thermal installations
This benefit varies depending on:
- Systems and Technologies that we use in our facilities
- Age of founding.
The more efficient and modern the systems, the lower the consumption of the house.
Efficiency of lighting systems
The key is an energy efficient home, Use of natural light and use of LED lighting systems or low consumption.
Minimal energy consumption
The application of the applicable technical building regulations is must have solar panels in the house to partially cover the water heating.
Tips for meeting the energy assessment requirements
Use of natural light and orientation of the house
This is an essential consideration in determining energy efficiency, since can have a major impact on the temperature and power consumption of your home. However, there is nothing more to be said at this point (unless you are planning to build a home) as it is all about improving existing homes.
Integrating renewable energy sources is a great way to achieve energy efficiency
Introduction of renewable energy sources
Whether photovoltaics, wind energy, geothermal energy, solar thermal energy … the list of alternatives to fossil fuels is growing over time and access to a form of renewable energy is becoming easier and easier. this has a direct impact on the amount of emissions generated by your house and thus in it energetic efficiency. It’s true that when it comes to a private home it’s easier, but there are more and more solutions for shared apartments like. shared self-consumption of solar energy, for example.
If we want to achieve energy efficiency, we have to isolate ourselves
Isolation optimization
Improving home insulation is imperative not only because it costs us less to reach a comfortable temperature, but also because that temperature can be maintained longer without using more energy. Nails Thermal break windows or one good roof insulation are some of the measures that you can take.
Replacement and renovation of energy systems
Choose a good, efficient and long-lasting heating system, replace your old appliances with low-consumption appliances or replace the electrical system with one that uses less energy; These are improvements that have a direct impact on your home’s energy use and emissions. While Choose the heating system it’s better for you and you have to think about it Distribution system what works best for you to maximize the effect of your exchanges on the energy efficiency of your home.
All of these improvements have an impact on your wellbeing at the same time Improve the energy efficiency of your home and you will have an impact on your pocket. For a house of 72 m², which is classified as type B in terms of energy, the average annual price is around EUR 200; for a type G house, the amount increases to EUR 1,000. are 800 euros difference only for heating.
