The design process for multifamily residential developments involves numerous decisions, some based on developer preference and others on state and local code requirements. Among these decisions, choosing the right HVAC system is crucial and should be made early on. There are two main categories of HVAC systems: Decentralized and Centralized.
Decentralized systems are often preferred for low and mid-rise buildings due to their affordability and flexibility. These systems, such as Self-Contained Packaged Heating & Air Conditioning (PTAC) units, offer individual unit control but may require more frequent maintenance and have a shorter lifespan compared to centralized systems.
The Fan Coil Unit with Integral Heat Pump System and Gas-Fired Furnace with Fan Coil Unit are other options within decentralized systems, offering varying levels of efficiency and cost.
Centralized systems, on the other hand, serve the entire building from a central location and are typically used in mid to high-rise buildings. They are more expensive to install but offer more sophisticated control and maintenance options. Options like the Vertical Stacked Water Source Heat Pump System and Variable Refrigerant Flow (VRF) System provide flexibility and energy efficiency but come with higher initial costs.
The choice between centralized and decentralized systems depends on factors such as building size, budget, and desired level of control and comfort. Understanding the pros and cons of each system is essential in making the right decision for your project. Erland offers expertise in guiding developers and design partners through this decision-making process for multifamily residential properties, ensuring the project’s success.
