Project
Improved comfort : Chilled beams provide superior thermal comfort by distributing conditioned air at a low velocity , minimising drafts and creating a more consistent temperature throughout the space . The slow air movement also reduces noise levels , creating a quieter and more comfortable environment for occupants .
Space optimisation : Chilled beams require smaller ductwork compared to VAV systems , freeing up valuable ceiling and void spaces . This allows for better space utilisation , increased flexibility in design , and potentially reduced construction costs .
Enhanced indoor air quality : Chilled beams rely on a separate air handling unit to supply fresh air , allowing for effective filtration and improved indoor air quality . This helps remove contaminants , allergens and pollutants , promoting a healthier environment for building occupants .
Longevity and low maintenance : Chilled beams have a longer lifespan compared to VAV systems , typically lasting up to 30 years . They have fewer moving parts , resulting in minimal maintenance requirements and lower ongoing operational costs .
Environmental sustainability : Chilled beams contribute to environmental sustainability by reducing energy consumption and carbon emissions . Their energy-efficient operation and potential for utilising renewable energy sources align with green building initiatives and sustainability goals .
Design flexibility : Chilled beams offer modular partitioning , allowing for flexible and adaptable space configurations . This
