In the coming years, thousands of buildings in Spain will need to undertake energy renovation measures.
Rising energy prices, new European efficiency requirements, and public subsidy programs are driving actions such as:
façade renovation
improvement of thermal insulation
installation of ETICS systems (External Thermal Insulation Composite Systems)
renovation of thermal installations
However, many homeowner associations and property managers are still unaware that part of these actions can generate Energy Savings Certificates (ESCs).
These certificates allow the energy savings achieved by a building to be converted into additional economic value, improving the profitability of renovation works.
At FESA, a company specialized in façade renovation and energy improvement of buildings, we work with homeowner associations and property managers who aim not only to renovate a building, but to do so efficiently and with optimized economic performance.
In this article we explain:
what Energy Savings Certificates (ESCs) are
why they are directly related to building renovation
which actions in homeowner associations can generate them
and why it is important to work with companies specialized in energy renovation.
What Energy Savings Certificates (ESCs) Are
Energy Savings Certificates (ESCs) are a system promoted by the Ministry for Ecological Transition that allows the certification of energy savings achieved after an improvement in a building or installation.
Each certificate represents:
1 kWh of final energy saved.
These certificates can be purchased by energy companies that are legally required to meet energy saving targets.
This means that when a building reduces its energy consumption thanks to a technical improvement, that saving can be converted into an economic asset within the energy system.
In simple terms:
If a building reduces its energy consumption after renovation, those savings can generate certificates with economic value.
Why ESCs Are Directly Linked to Building Renovation
The ESC system is especially connected to actions that improve the energy efficiency of buildings.
These include:
improving thermal insulation
energy renovation of façades
installation of ETICS systems
renovation of heating systems
replacement of thermal equipment with more efficient systems
All these actions have a direct impact on the building’s energy consumption, making it possible to quantify the savings generated over many years.
For this reason, energy renovation of buildings has become one of the areas with the greatest potential for the ESC system.
Which Actions in Homeowner Associations Can Generate ESCs
Many common renovation actions in homeowner associations can generate energy savings certificates.
The most relevant ones are related to the building’s thermal envelope.
Energy Renovation of Façades
Improving the façade is one of the actions with the greatest impact on a building’s energy consumption.
A poorly insulated façade causes:
heat loss in winter
excess heat in summer
higher heating and cooling consumption
Façade renovations through:
ETICS systems
ventilated façades
improved insulation
can significantly reduce the building’s energy demand.
These savings can be certified within the ESC system.
Improving the Building’s Thermal Insulation
Improving insulation in:
façades
roofs
party walls
reduces the need for heating and cooling and improves indoor comfort in homes.
These actions also generate measurable energy savings over many years.
Renovation of Thermal Systems
Some homeowner associations take advantage of renovation works to upgrade:
central heating systems
old boilers
air conditioning systems
Replacing them with more efficient systems can also generate energy savings certificates.
What Benefits a Homeowner Association Can Obtain
The ESC system can provide several advantages when undertaking an energy renovation.
Improving the Profitability of Renovation Works
Energy renovation projects often require a significant investment from the community.
ESCs allow the generation of an additional economic return linked to the energy savings achieved.
Complementing Public Subsidies
In many cases, homeowner associations access:
European funds
regional subsidies
energy renovation programs
The ESC system can complement these subsidies, improving the economic feasibility of the project.
Reducing the Building’s Energy Consumption
Beyond the economic aspect, energy renovations allow:
reducing energy consumption
improving thermal comfort in homes
increasing the building’s value in the real estate market
The Role of Companies Specialized in Energy Renovation
To properly take advantage of the opportunities associated with energy efficiency, it is essential that renovation measures are correctly designed from the beginning.
For homeowner associations this involves:
carrying out a technical diagnosis of the building
properly defining renovation solutions
executing the works with energy efficiency criteria
At FESA we have years of experience in façade renovation and building energy improvement, working closely with property managers and homeowner associations.
Our approach is clear:
It is not just about renovating a building, but about doing so while optimizing its energy efficiency and long-term profitability.
ESCs and Energy Renovation: An Opportunity Many Communities Still Do Not Know About
The ESC system is still relatively new in Spain.
For this reason, many homeowner associations are carrying out energy renovations without taking advantage of the full potential offered by this mechanism.
However, everything suggests that Energy Savings Certificates will become increasingly relevant in financing energy improvements in buildings.
For property managers and homeowner associations, understanding this system can make the difference between:
a conventional renovation
or an energetically optimized renovation.
Conclusion
Energy renovation of buildings will be one of the major challenges for the Spanish building stock in the coming years.
Energy Savings Certificates (ESCs) represent a new tool that makes it possible to:
reduce the energy consumption of buildings
improve the comfort of homes
and generate additional economic value
However, to take advantage of these opportunities, it is essential to work with companies specialized in energy renovation and façade rehabilitation that know how to properly design these interventions.
Because when a building is renovated, it is not only its exterior appearance that improves.
Its efficiency, its value, and its energy future can also improve.
