EPC Limitations for Hyperloop Station Buildings with High Passenger Flux

Hyperloop stations are an emerging infrastructure type, designed to handle high volumes of passengers with rapid throughput, complex mechanical systems, and innovative building designs. While Energy Performance Certificates (EPCs) are used to assess building energy efficiency, hyperloop stations present unique challenges that can affect the accuracy

EPC Ratings for Historic Properties with Replica Thermal Materials

Historic buildings often have unique construction materials and architectural features that make standard energy efficiency assessments challenging. When renovating or restoring these properties, builders sometimes use replica thermal materials—modern materials designed to mimic the appearance of traditional masonry, timber, or stone while providing better insulation. EPCs

How EPC Treats Naturally Aspirated Passive Cooling Towers?

Naturally aspirated passive cooling towers are structures designed to cool water or air without mechanical fans, relying on natural airflow and evaporation. They are commonly used in sustainable buildings, industrial facilities, and water-side HVAC systems. While highly energy-efficient, these systems present unique challenges for Energy Performance

Challenges in EPC for Modular Pop-Up Commercial Structures

Modular pop-up commercial structures—temporary or semi-permanent buildings used for events, retail kiosks, or exhibitions—are increasingly popular due to their flexibility, speed of deployment, and cost-effectiveness. However, these structures present unique challenges for Energy Performance Certificate (EPC) assessments. EPCs evaluate a building’s energy efficiency based on insulation,

EPC Modelling for Roof Surfaces with Mixed Solar PV and Green Roofing

Modern sustainable buildings increasingly use mixed roof surfaces—combining solar photovoltaic (PV) panels with green (vegetated) roofing. While these designs improve energy efficiency and environmental performance, they present unique challenges for EPC (Energy Performance Certificate) modelling. EPCs are designed to estimate a property’s energy efficiency based on

Impact of Floating Solar Arrays on EPC Water-Side Energy Efficiency

Floating solar arrays (also called floating photovoltaics or FPVs) are solar panels installed on bodies of water, such as reservoirs, lakes, or retention ponds. They offer renewable energy generation while reducing land use. Beyond electricity generation, floating solar panels can also affect a building’s water-side energy

EPC Accuracy for Properties Using Groundwater Heat Extraction Wells

Geothermal systems, such as groundwater heat extraction wells, are becoming increasingly popular for heating and cooling modern homes. By using water from underground aquifers, these systems can transfer heat efficiently, reducing reliance on conventional energy sources. However, they present unique challenges for Energy Performance Certificate (EPC)

Why EPC Models Struggle with Variable Opacity Glass Walls?

As building technology evolves, innovative materials like variable opacity glass walls—also called smart or electrochromic glass—are becoming more common. These walls can adjust transparency to let sunlight in or block heat and glare, providing comfort and energy savings. However, they also create challenges for Energy Performance

EPC Ratings for Homes with Seasonal Sliding Roofs

An Energy Performance Certificate (EPC) evaluates a property’s energy efficiency, assigning a rating from A (most efficient) to G (least efficient). The assessment considers various factors, including insulation, heating systems, and ventilation. Learn more about our company and services on our About Us page. Impact of

Impact of Airborne Dust in Desert Climates on EPC Solar Gain Calculations

In desert regions, Energy Performance Certificate (EPC) assessments face a unique environmental factor — airborne dust. While most EPC models assume consistent solar exposure based on climate data, high dust concentrations can significantly reduce solar gain, affecting both heating and cooling projections.
