Thermal & Energy Analysis

Thermal & Energy Analysis

At NFEStructural, we ensure that facade systems contribute to energy efficiency, occupant comfort, and regulatory compliance. Using advanced thermal modeling, condensation risk assessment, and energy performance simulations, we optimize facade design for sustainability, insulation, and cost-effectiveness.

1. Thermal Performance Analysis

We assess how different façade materials and design strategies impact a building’s thermal efficiency to minimize heat loss, reduce energy consumption, and improve insulation performance.

Key Thermal Performance Factors:

✅ U-Value (Thermal Transmittance) Calculations – Evaluating heat loss through facade elements to meet UK Part L, ASHRAE 90.1, and Passive House standards.
✅ Thermal Bridging Analysis – Identifying and mitigating high-conductivity areas using thermal break materials in aluminum and steel facades.
✅ Dynamic Thermal Modeling (DTM) – Simulating facade performance across seasonal changes, assessing solar radiation, ventilation, and shading impact.

2. Condensation Risk Analysis

Condensation in facades can lead to mold growth, structural damage, and insulation inefficiencies. We conduct detailed condensation risk assessments to prevent these issues.

Key Considerations:

✅ Dew Point Analysis – Identifying temperature thresholds where condensation forms, using psychrometric charts and hygrothermal simulations.
✅ Surface & Interstitial Condensation Prevention – Ensuring thermal breaks, ventilated cavities, and optimized insulation placement.
✅ Hygrothermal Modeling (WUFI Simulation) – Predicting moisture accumulation and condensation risks over time to comply with BS 5250 and ASHRAE 160.

3. Energy Efficiency Optimization

We enhance facade designs to maximize energy savings, reduce carbon footprints, and improve occupant comfort.

Key Energy Optimization Strategies:

✅ Solar Heat Gain Coefficient (SHGC) Analysis – Optimizing low-E coatings, fritted glass, and dynamic glazing to regulate solar radiation absorption.
✅ Building Envelope Optimization – Using high-performance insulation materials like aero-gel, PIR insulation, and vacuum-insulated panels for superior thermal resistance.
✅ Passive Design Strategies – Incorporating natural ventilation, operable facades, and thermal mass storage to reduce HVAC dependency.
✅ Energy Savings Predictions – Using IES VE, EnergyPlus, and TAS to model energy consumption and calculate potential savings, CO₂ reductions, and ROI.

4. Compliance with Sustainability & Energy Standards

We ensure that facade systems meet global and regional energy efficiency standards, reducing operational costs and environmental impact.

Key Standards & Certifications:

✅ UK Building Regulations (Part L & SAP 10) – Compliance with thermal efficiency requirements.
✅ LEED & BREEAM Certification – Optimizing facades to earn green building certification credits.
✅ ASHRAE 90.1 & ASHRAE 189.1 – Meeting US energy-efficient building envelope requirements.
✅ Passive House (Passivhaus) Design – Engineering ultra-low energy facades for maximum efficiency.
✅ EU Energy Performance of Buildings Directive (EPBD) – Aligning with zero-energy building targets.

5. Solar Heat Gain & Daylighting Studies

We analyze the impact of solar radiation on building performance, ensuring thermal comfort, glare control, and optimal daylight distribution.

Key Solar & Daylight Strategies:

✅ Glare Control & Visual Comfort – Using tinted, fritted, or dynamic glazing to reduce glare while maintaining natural light penetration.
✅ Daylight Factor Calculations – Ensuring EN 17037 and WELL Building Standard compliance for adequate indoor daylight exposure.
✅ Shading Device Optimization – Designing external louvers, brise soleil, and overhangs to balance solar heat gain and winter insulation.

6. Thermal Simulation & Performance Testing

We use cutting-edge thermal simulation tools and real-world testing to predict how facades will perform in different climatic conditions.

Key Simulation Methods:

✅ Computational Fluid Dynamics (CFD) for Airflow & Ventilation – Optimizing natural and mechanical ventilation for improved indoor air quality.
✅ Finite Element Analysis (FEA) for Thermal Stress – Identifying temperature-induced stress points in facade materials to prevent thermal breakage and expansion failures.
✅ Hot Box Testing for Insulation Performance – Measuring U-values in controlled conditions to validate insulation effectiveness.
