Partial subterranean cooling loops are an energy-efficient solution where part of the HVAC system exchanges heat with the ground. These systems leverage the stable underground temperature to pre-cool or pre-heat air, reducing building energy demand. However, they introduce specific challenges for Energy Performance Certificate (EPC) assessments.
Dynamic thermal mass walls, constructed from materials like phase-change plaster or concrete with high heat capacity, can absorb and release heat throughout the day. This moderates indoor temperatures and reduces HVAC loads. However, these dynamic properties introduce challenges for Energy Performance Certificate (EPC) assessments. 1. Understanding
Multi-zone radiant floor heating systems provide precise temperature control for different areas within a building. While they improve occupant comfort and energy efficiency, their complexity can introduce variability in Energy Performance Certificate (EPC) ratings if not accurately modelled. 1. Understanding Multi-Zone Radiant Floor Systems Definition: Heating
Buildings with high roof-to-floor ratios, such as warehouses, atriums, and some residential lofts, present unique challenges for Energy Performance Certificate (EPC) assessments. A disproportionally large roof area relative to the floor can significantly influence heat loss, solar gain, and overall energy efficiency, potentially leading to EPC
Smart phase-change windows (PCWs) are an innovative building technology that adjusts transparency and thermal properties in response to sunlight and indoor climate conditions. These windows can reduce cooling loads in summer and improve insulation in winter, making them highly effective for energy efficiency. However, their dynamic
Buildings with moisture-buffering materials in their envelopes, such as hygroscopic walls or phase-change interior finishes, can naturally moderate indoor humidity and temperature fluctuations. While this improves occupant comfort and reduces HVAC demand, it introduces complexities for Energy Performance Certificate (EPC) modelling. 1. Understanding Seasonal Envelope Moisture
Hybrid ground-air heat exchangers (HGAHEs) combine the benefits of ground-source and air-source thermal energy to provide efficient heating and cooling. These systems are increasingly used in dense urban areas where space and environmental constraints limit conventional HVAC solutions. However, their integration poses unique challenges for Energy
Accurate energy performance assessment depends on correctly modelling a building’s thermal envelope. Roof insulation is a critical factor, and non-uniform insulation with variable thickness poses challenges for Energy Performance Certificate (EPC) calculations. 1. Understanding Non-Uniform Roof Insulation Non-uniform roof insulation occurs when: Insulation layers vary in
Groundwater heat exchangers (GWHEs) are a key component of geothermal heating and cooling systems. They transfer heat between the building and underground water sources, providing an energy-efficient solution for temperature regulation. However, variations in GWHE efficiency can significantly impact Energy Performance Certificate (EPC) ratings. 1. How
Building-Integrated Thermal Storage (BITS) systems, such as phase change materials (PCMs) and embedded water tanks, offer innovative solutions to enhance energy efficiency by storing thermal energy within the building envelope. However, accurately modelling these systems for Energy Performance Certificates (EPCs) presents several challenges: 1. Dynamic Thermal
