CHAPTER 4. NON-TECHINCIAL ASPECT 4.1. INTRODUCTION The chapter highlights the non-technical aspects of ventilation systems in sports halls, focusing on their economic, environmental, and social impacts. Economically, efficient ventilation systems can reduce energy costs and maintenance expenses, enhancing the facility's value and attracting more users. Environmentally, these systems help lower the carbon footprint by minimizing energy consumption and supporting sustainability goals. Socially, improved air quality and climate control enhance the health and comfort of athletes, spectators, and staff, promoting a positive community image and increasing participation in sports activities. Thus, effective ventilation systems are crucial for holistic sports facility management. 4.2. FINANCIAL & COST OF PROJECT The cost of a ventilation system for a sports area hinges on several key components. Firstly, ductwork expenses are influenced by factors such as material choice, size, and installation requirements. Similarly, diffusers, essential for distributing airflow, vary in cost based on design and quantity needed. Fans, along with volume dampers for airflow regulation, constitute another significant expense, dependent on factors like size and energy efficiency. Lastly, hangers, necessary for supporting ductwork, also contribute to overall costs. Balancing these factors ensures the ventilation system effectively meets the area's needs while remaining within budget constraints. The prices are shown in Table 4-1. 4.3. EHTICAL & SOCIAL The design of a ventilation system for a sports area involves ethical and social considerations that extend beyond technical aspects. Ethically, ensuring the health and safety of athletes, spectators, and staff is paramount. Adequate ventilation helps maintain indoor air quality, reducing the risk of respiratory issues and the spread of airborne illnesses, which is particularly crucial in light of recent public health concerns. Additionally, considering the environmental impact of the ventilation system, such as energy efficiency and carbon emissions, aligns with ethical principles of sustainability. 4.4. ENVIROMENT AND SUSTAINBILITY One aspect of environmental sustainability involves minimizing energy consumption. Designing ventilation systems with energy-efficient components, such as high-efficiency fans and motors, can reduce energy usage and greenhouse gas emissions. Additionally, incorporating advanced control systems, such as variable air volume (VAV) systems or demand-controlled ventilation, can further optimize energy efficiency by adjusting airflow based on occupancy and activity levels in the sports area. Furthermore, selecting environmentally friendly materials for ductwork, diffusers, and other system components can reduce the environmental footprint of the ventilation system. Using recycled materials or those with low embodied carbon can help minimize resource depletion and environmental pollution.
