Join this Tech Talk to learn more on how to design HVAC systems with reduced energy consumption, meeting new requirements on noise, or refrigerants usage.
Heating Ventilation and Air Conditioning (HVAC) systems have become an essential part of building equipment, ensuring superior Indoor Environmental Quality (IEQ), especially around Thermal Comfort and Interior Air Quality (IAQ). Conversely, HVAC energy consumption can represent up to 40% of overall building energy expenditures in countries with extreme weather conditions. To curb this trend, government policies such as the Leadership in Energy and Environmental Design (LEED) are promoting green HVAC through tax incentives. As a result, the correct design and integration of an HVAC system in a building can strongly affect its financial viability.
New simulation capabilities can provide insights into the performance of an HVAC, and help improve its integration in the building, before even breaking ground on construction. To promote seamless coupling and change management at every stage of a project, multiscale and multiphysics solutions are necessary. Designing an HVAC system involves balancing the performance of the components, with that of the system assembly, validating thermal, structural, or even acoustic targets. When looking at building integration, 1D HVAC system models and 3D building models need to be simulated in an integrated solution. This solution can include zonal 1D and detailed 3D representations of a building to investigate key performance indicators for energy consumption, thermal comfort and IAQ, and assess present and even future usage scenarios.
