The energy consumption of a home not only affects the monthly bill. It also influences comfort, the value of the property and the sustainability of the environment. In cities like Rubí, where a good part of the housing stock is more than twenty years old, improving energy efficiency has become a priority for both owners and tenants.
In Havitec We see every day how small improvements can reduce lighting and heating consumption, increase thermal comfort and improve the home's energy label. This guide brings together the most effective actions for those who want to optimize their home in 2025 without carrying out major renovations.
Why energy efficiency is so important in Rubí
Rubí combines old residential areas with more modern homes. In many cases, properties built before 2006 have insufficient insulation, old windows and inefficient air conditioning systems.
This translates to:
Higher energy bills
Less comfort in winter and summer
Worst energy label
Less attractive homes for future buyers or tenants
Improving energy efficiency is not only an economic issue, but an investment in long-term comfort and value.
Insulation: the basis of energy efficiency
Proper insulation is the first step to improving the efficiency of any home. In Rubí it is especially relevant due to the temperature variations between seasons.
Key actions:
Check the condition of the insulation in walls and ceilings
Insulate false ceilings or air chambers
Seal air leaks in windows and doors
Good insulation reduces the need for heating and air conditioning, thus reducing overall consumption.
Double-glazed windows: a simple change with immediate impact
Older windows with aluminum frames without thermal break or with single panes allow temperature leaks. Changing them to double-glazed or PVC windows significantly improves efficiency.
Direct benefits:
Lower thermal loss
Reduction of external noises
Greater comfort in summer and winter
Best letter in the energy certificate
It is one of the most profitable medium-term investments in Rubí homes.
LED lighting: small change, big savings
Replacing all lighting with LED bulbs reduces electricity consumption by up to 80%. They are more efficient, last longer and produce less heat.
In many homes, this simple step already represents significant savings.
In Havitec We recommend carrying out an analysis of the light points to optimize distribution and also improve aesthetics.
Efficient devices: choosing well makes the difference
In kitchens and bathrooms, old appliances are responsible for a significant portion of energy consumption. Equipment labeled A, A+ or A++ can drastically reduce the bill.
Appliances with the greatest impact:
Fridge
Washing machine
Oven
Air-conditioning
For homeowners who want to increase the overall value of the home, upgrading these appliances is a strategic improvement.
Modern air conditioning systems
Older heating and air conditioning systems consume more than necessary.
Updating this equipment improves both consumption and comfort.
Efficient options:
High efficiency heat pumps
inverter air conditioning
Condensing boilers
In Rubí homes with old electric heating, a heat pump can reduce consumption by up to 40%.
Intelligent consumption control
Smart devices allow you to optimize energy use without carrying out works. Thermostats, adjustable plugs and control assistants can reduce consumption through automatic programming.
Advantages:
More precise temperature control
Less unnecessary consumption
Usage history to adjust habits
This type of technology is inexpensive and easy to install.
Small reforms with real impact
There are improvements that, without being major reforms, provide a notable leap in efficiency.
Simple renovations recommended by Havitec
Install weather stripping on doors
Replace faucets with models with flow limiter
Add thermal mats in winter
Use light colors that better reflect natural light
Small adjustments that add up to a more efficient and comfortable home.
Take advantage of natural light: a free resource
Rubí has many hours of sunlight throughout the year. Using it correctly reduces the need for artificial lighting.
Practical recommendations:
Avoid thick curtains
Keep windows clear
Choose light furniture
Distribute spaces to allow light to pass through
Natural light also improves the perception of space, something highly valued in older homes.
The aid available in Catalonia in 2025
Many homeowners are unaware that there are aid and subsidies to improve energy efficiency. Depending on the type of action, the Generalitat de Catalunya covers between 20% and 80% of the cost.
In Havitec We inform our clients about what aid they can request, how to process it and what documentation they need.
Does improving energy efficiency increase home value?
Yeah.
Homes that have improved their energy efficiency usually:
Increase your value
Reduce sales times
Attract buyers with greater purchasing power
More and more families are looking for homes with a better energy label, especially A, B or C.
At Havitec we observe that a good level of efficiency can make the difference between a home that sells quickly and another that remains on the market for months.
Conclusion: energy efficiency as a long-term investment
Improving energy efficiency in a Rubí home is a smart investment that is recovered through savings, comfort and equity value. It is not only about reducing consumption, but about preparing a home for the future and increasing its competitiveness in the market.
In Havitec, we advise owners and residents to identify which improvements add the most value depending on the type of home, its age and its current condition. Our commitment is to help make each Rubí home more efficient, comfortable and sustainable.
