Building Performance Analysis

Comprehensive building performance analysis for homes and properties

Building performance analysis goes beyond basic surveys to examine how a property actually behaves in real-world conditions.

It helps identify heat loss, ventilation issues, moisture risks, and inefficiencies that affect comfort, running costs, and long-term building health.

At E&F Retrofit Services Ltd, we use data-driven methods and hands-on expertise to analyse how your building performs and where improvements will have the biggest impact.

Based in Wrexham, we work with homeowners, landlords, housing associations, and contractors across North and Mid Wales.

What is building performance analysis?

Building performance analysis focuses on understanding how a building interacts with heat, moisture, ventilation, and occupancy patterns.

Instead of relying solely on theoretical models, we assess how the property performs under real conditions.

This information is essential for planning retrofit works, resolving comfort issues, preventing damp or mould, and improving energy efficiency.

What our building performance analysis covers

1. Thermal Performance and Heat Loss

We examine how effectively the building retains heat, including:

• Fabric heat loss and thermal inefficiencies
• Cold spots or areas with significant temperature variation
• Insulation effectiveness and missing insulation risks

Identifying these issues helps guide targeted improvements.

2. Ventilation and Airflow Behaviour

Proper ventilation is essential for indoor air quality and moisture control. We assess:

• Natural and mechanical ventilation performance
• Air movement patterns
• Risk areas for condensation and mould

3. Moisture and Damp Risk Assessment

Moisture can lead to major building problems if not managed correctly. Our analysis highlights:

• Sources of moisture ingress
• Humidity patterns linked to occupancy
• Areas vulnerable to damp or mould

4. Heating and Hot Water Performance

We evaluate how efficiently your heating and hot water systems operate, including:

• System responsiveness and distribution
• Radiator performance and balance
• Opportunities for system optimisation

5. Building Use and Occupancy Patterns

Occupant behaviour affects energy use. We gather insights on:

• Heating schedules and control settings
• Ventilation habits
• Space usage and comfort requirements

This helps ensure recommendations are practical and matched to real-world needs.

Why building performance analysis matters

A building may look fine on the surface while still suffering from hidden inefficiencies that increase bills, reduce comfort, and risk long-term damage. Building performance analysis helps you:

• Pinpoint causes of cold rooms or high heating costs
• Identify and prevent damp, condensation, or mould
• Plan effective energy efficiency improvements
• Improve indoor comfort and air quality
• Support PAS 2035 and whole-house retrofit planning

Who benefits from building performance analysis?

Our service is ideal for:

• Homeowners wanting to improve comfort and reduce bills
• Landlords preparing for energy standards or portfolio upgrades
• Housing associations managing multiple properties
• Contractors and retrofit coordinators needing accurate building data
