Fabric Upgrades

The building fabric – including the roof, walls, floors, windows, doors and airtightness – plays a fundamental role in determining how much energy a building needs to operate.

At Tipperary Energy Agency, we assess the existing fabric and identify opportunities to reduce heat loss, improve thermal comfort and create a more efficient building.

Whether you are considering a deep retrofit or a medium-depth retrofit, we can help develop a fabric strategy that balances energy performance, capital cost, building condition, operational requirements and long-term objectives.

A well-designed fabric upgrade can also reduce heating and cooling demand, improve the performance of HVAC systems and create better conditions for the future integration of low-carbon technologies such as heat pumps.

How can TEA help?

Our building fabric assessments and retrofit feasibility studies help you determine the most effective and practical way to improve your building’s performance.

We assess the existing building envelope, insulation, glazing, airtightness, ventilation and thermal performance to identify the measures that can deliver the greatest overall benefit.

As part of our building fabric assessment, we can provide:

An evaluation of the existing building envelope and condition

Identification of heat-loss areas, thermal bridges and performance gaps

Assessment of existing insulation, glazing, windows and doors

Consideration of airtightness and infiltration

Energy, carbon and cost analysis of proposed measures

Recommendations for whole-building or individual fabric improvements

Guidance on cost-effectiveness and potential phasing of works

Assessment of how fabric improvements will affect heating, cooling and ventilation requirements

Assessment of ventilation requirements and potential moisture or condensation risks

Our goal is to ensure you invest in the right fabric improvements, at the right scale and at the right time, with a clear understanding of the expected energy, carbon, comfort and financial benefits.

Reduced energy and maintenance costs

Lower energy consumption and fewer equipment failures result in long term operational savings.

Better temperature control and improved thermal comfort

Enhanced insulation and building fabric improvements help maintain stable indoor temperatures for occupants.

Improved productivity

Reducing draughts, solar glare, overheating, cold spots and noise creates a more comfortable environment, supporting better output and morale.

Lower capital expenditure

A well insulated, efficient building requires smaller heating and cooling systems, and in some cases eliminates the need for certain equipment entirely.

Strong long-term investment

Upgrading insulation, maintaining the building fabric, or upgrading windows and doors can increase property value, improve aesthetics and enhance overall building performance.

Compliance with regulations

Government standards require minimum efficiency levels for both new and existing buildings, and improved building fabric helps ensure compliance.

Improving your building’s fabric can significantly enhance energy efficiency, comfort and long‑term performance. There are typically two main approaches:

This allows you to address multiple elements of the building fabric at once, maximising energy savings and improving overall cost‑effectiveness. By combining measures, such as installing insulation alongside new windows, you can design a more efficient, integrated solution. This approach also enables the development of an optimised low‑energy heating, ventilation and air‑conditioning (HVAC) strategy, as the improved fabric reduces heat loss and stabilises indoor temperatures. 

This focuses on one specific improvement at a time and is the most common type of building upgrade. Typical measures include roof insulation, wall insulation, new windows or draught‑proofing. These targeted interventions can deliver meaningful improvements in comfort and energy performance. However, it is important to consider how each measure interacts with the rest of the building. For example, adding insulation should always be accompanied by a review of ventilation to prevent issues such as surface or interstitial condensation.

Both methods can significantly improve performance, but the optimal solution will depend on your building’s existing fabric, financial constraints and long‑term operational strategy.

What types of fabric upgrades are available?

Common upgrades include roof and wall insulation, improved glazing, draught‑proofing, airtightness improvements and enhancements to ventilation systems. The right measures depend on your building’s age, condition and performance goals. 

How do I know which upgrades my building needs?

A building fabric assessment identifies heat‑loss areas, insulation gaps and ventilation issues. This ensures upgrades are targeted, effective and compatible with the rest of the building. 

Will fabric upgrades disrupt building operations?

Most upgrades can be completed with minimal disruption. Single‑measure improvements such as draught‑proofing or insulation can often be carried out quickly, while larger refurbishments may require phased planning. 

Are fabric upgrades only about saving energy?

No. They also improve comfort, reduce noise, stabilise indoor temperatures and enhance the overall condition and value of the building. 

Do I need to consider ventilation when upgrading insulation?

Yes. Adding insulation without reviewing ventilation can lead to condensation or moisture issues. A balanced approach ensures both efficiency and building health. 

Who should consider fabric upgrades?

Any building with high energy use, comfort issues, ageing insulation or plans for HVAC upgrades can benefit from fabric improvements. 

Are there any lower interest loans available to me?

Yes. Banks and credit unions offer discounted finance to businesses undertaking sustainable initiatives to reduce their carbon footprint and operating costs. Our team can help you identify suitable funding options and guide you through the application process.
