Heating and cooling load assessment is an essential service that determines the precise Heat loss and Heat gain of your building, enabling accurate sizing of HVAC systems for both heating and cooling. Heat loss refers to the warmth that escapes through walls, windows, and other building components during colder months, while heat gain includes heat entering from solar radiation, equipment, lighting, and occupants during warmer periods. By carefully analyzing these factors along with insulation, ventilation, and local climate conditions, we ensure your HVAC system is designed to maintain optimal comfort and energy efficiency year-round.

Our expert load assessment service guarantees that your HVAC equipment meets the exact peak heating and cooling demands of your building without being over- or undersized. This results in enhanced energy savings, lower operating costs, improved system longevity, and consistent indoor temperature and humidity control. Trust us to deliver a tailored HVAC solution based on a thorough understanding of your building’s unique thermal performance, ensuring maximum comfort and cost-effectiveness.

Our Thermal Comfort Analysis service specializes in detailed overheating assessments across all building types, utilizing established CIBSE methodologies to ensure indoor environments remain comfortable and safe. For residential buildings, we follow CIBSE TM59, which provides a dynamic thermal modeling approach to assess risk by evaluating temperature thresholds within living spaces, including bedrooms, based on adaptive comfort criteria. For commercial properties, we apply CIBSE TM52, which focuses on evaluating the number of hours spaces exceed specific temperature limits during occupied periods, helping identify overheating risks and inform mitigation strategies.

In addition to CIBSE standards, we incorporate relevant guidelines such as BB101 for schools, focusing on classroom overheating risks, and HTM for hospitals, addressing thermal comfort for vulnerable occupants. Our comprehensive assessments analyze heat gains from solar radiation, internal occupancy, equipment, and building fabric, using real-world weather and occupancy data to simulate building performance. The resulting reports identify potential overheating issues and propose targeted measures including shading control, ventilation enhancements, and fabric improvements to optimize comfort, energy efficiency, and compliance with regulatory requirements.

We evaluate your building’s entire thermal envelope—including walls, roofs, floors, and windows—to ensure it retains heat effectively. Optimizing these physical elements is the foundation of energy-efficient design, significantly reducing the need for artificial heating and cooling.

Our technical services include:

• U-value Calculations: Precise measurements of heat transfer (both simple and complex).
• Thermal Bridging Analysis: Identifying specific junctions where heat escapes.
• Thermography: Using thermal imaging to visualize performance gaps.
• Moisture Assessments: Evaluating risks of dampness and condensation.
• Solar Heat Gain Studies: Analyzing how the sun impacts internal temperatures.

​

A thermal bridge occurs when your building’s insulation layer is interrupted by materials that conduct heat easily, such as structural steel or concrete lintels. These “bridges” create a pathway for heat to escape, resulting in higher energy bills and a significant risk of condensation or mould growth.

We help architects and contractors identify and resolve these weak points before they become a problem. Our specific services include:

• Junction Assessment: Pinpointing areas where insulation is bypassed or compromised.
• Detailed Calculations: Providing precise 2D and 3D thermal modeling to quantify heat loss.
• Design Optimization: Refining construction details to meet building regulations and prevent moisture issues.
