Energy Renovation and Building Upgrades

Improve your property's energy performance

Energy renovation takes a comprehensive approach to improving a building's energy performance.

An older property may require more heating and cooling because of outdated windows, insufficient insulation, older heating systems or other technical characteristics.

An energy upgrade is not a single task. Depending on the building, it may involve a combination of interventions that should be considered together.

At IG Constructions, we approach every project according to the property's actual characteristics and the owner's needs.

What is energy renovation?

Energy renovation includes interventions intended to improve a building's energy efficiency. Possible measures vary from property to property and may include:

• thermal insulation,
• replacement of windows and frames,
• improved waterproofing and air sealing,
• heating and cooling system upgrades,
• hot-water systems,
• lighting improvements,
• other energy-related interventions.

The right measures should be selected after a technical assessment.

Why does a building's energy performance matter?

A building's energy performance affects its heating and cooling needs and its overall energy use. An older property may lose energy through its envelope, windows or other building elements.

Depending on the construction and technical possibilities, an upgrade may address some of these issues.

Thermal insulation

Thermal insulation is one of the main types of energy intervention. Depending on the existing construction, it may apply to different parts of the building. The system and materials should be selected through sound technical design based on the building's requirements.

Windows and frames

Windows and frames are an important part of a building's envelope. Older units may provide insufficient thermal performance or have sealing problems. Replacement can be considered as part of a wider energy upgrade.

Choosing a product alone is not enough. The overall construction, installation and other building elements should also be considered.

Heating and cooling

Heating and cooling systems play an important role in a home's energy performance. As part of a renovation, the existing installation can be assessed and alternative options considered.

The right choice depends on the property's size and use, its location, the building envelope and other technical factors.

Energy renovation of an older home

Older homes are often candidates for significant energy improvements, but each case is different. The existing condition should be recorded before work begins.

The building's age, wall construction, roof or terrace condition, windows and heating systems should all be assessed together.

Energy upgrades for an apartment

The options in an apartment may differ from those in a detached home. Some elements belong to the apartment alone, while others relate to the building as a whole.

It is therefore important to assess what is technically possible and which procedures may be required.

Energy renovation and home renovation

An energy upgrade can be combined with a broader home renovation. For example, when a home is being fully renovated, windows, insulation and heating systems can be assessed at the same time. This allows the interventions to be planned from the outset.

How much does energy renovation cost?

The cost depends on the type and extent of the interventions. Replacing windows has a different cost from a complete project involving insulation, heating and other works.

There is no single price for every property without a prior technical assessment.

Energy upgrades and subsidy programmes

Government or other programmes for energy improvements may be available from time to time. Their terms, eligibility requirements and availability change, so applicants should check the current framework and official requirements at the time of application.

Plan carefully before work begins

Energy renovation should not start with an arbitrary choice of products. The building must first be understood, then the appropriate combination of interventions can be selected.

A technical assessment can help set priorities and establish a realistic budget.

Why IG Constructions?

Energy upgrades require technical knowledge and careful coordination. At IG Constructions, we can assess your property's needs and organise the required work as part of a comprehensive renovation.

From the site visit and planning through to delivery, the aim is to make every intervention part of an overall plan.

Frequently asked questions

What does energy renovation include?

Depending on the property, it may include insulation, windows, heating and cooling systems or other energy improvements.

Which intervention is right for my property?

There is no single solution for every building. The existing condition needs to be assessed first.

Is energy renovation worthwhile for an older home?

Whether it is worthwhile depends on the property's condition, its needs and the cost of the required interventions.

Can energy upgrades be combined with a full renovation?

Yes. In many cases, combining them can make it easier to plan the works as a whole.
