AIVC's Ventilation Information Paper #46: Building airtightness impact on Energy Performance (EP) calculations aims to explain simplified models developed and used around the world to estimate the infiltration rate for Energy Performance (EP) calculations and give some examples of methodologies applied in various countries.
Although indoor air has received less attention compared to outdoor air, it is important to improve indoor air quality as indoor pollution can lead to several health effects.
This article presents a simulation-based approach to assess the readiness of dwellings for adopting lower-temperature heat from district heating systems as a means of gas-free heating transition.
The paper highlights the potential and limitations of digital methods concerning regenerative design and suggests possibilities for future expansion by incorporating additional quantifiable indicators that reflect research developments, to achieve positive outcomes.
A survey conducted by Building Research Establishment (BRE) found that fixing poor quality houses can bring £135.5bn of benefits over the next 30 years.
An indoor ambient simulation is useful to quantitatively assess the performance of Heating, Ventilation and Air Conditioning (HVAC) systems and predict the air flows needed for optimal comfort in any season. Hence, it is possible to reduce energy consumption, simulate air purification, enhance thermal comfort, and optimise HVAC configurations, especially when different system solutions are integrated in the same building.
