Higher construction costs, tighter lot sizes, and continued demand for multifamily housing are pushing project teams to rethink how space is allocated. This shift has particularly driven the development of more flexible HVAC system platforms, as HVAC design significantly influences how units are laid out and how projects perform financially.

Designing for Space Efficiency

Space efficiency is now a primary consideration across multifamily new construction and retrofit projects. Architects and builders are placing greater emphasis on HVAC integration within the building envelope.

Systems with smaller footprints that maintain performance are gaining attention. Within platforms like the EVOX lineup from Midea, a member of the NAHB Leading Suppliers Council, this includes a mix of ducted, ductless, and ceiling-mounted compact air handling solutions.

Rethinking the Mechanical Closet

Mechanical closets occupy floor area that could otherwise support living space or more storage. Ceiling-mounted air handling systems offer an alternative. By relocating equipment into the ceiling cavity, project teams can reclaim floor space while maintaining performance.

Ceiling-mounted systems can eliminate the need for a dedicated mechanical closet. And choosing one that is designed to integrate with existing ductwork and controls will enable you to avoid making major structural or electrical modifications.

Designing Within Real-World Constraints

Projects frequently involve limited ceiling plenum space, existing ductwork, and legacy control systems. Redesigning around these constraints can add cost and delay. HVAC systems that adapt to these conditions simplify installation.

Key considerations include compact equipment profiles, compatibility with standard 24V controls, and sufficient static pressure to support existing duct layouts. Platforms that support both traditional 24V and advanced communication protocols allow builders to integrate new equipment without overhauling existing infrastructure.

Maintaining Performance and Comfort

Reducing the HVAC footprint does not mean sacrificing performance. Modern heat pumps can deliver reliable heating and cooling across a range of climate conditions and building types — and they’re being designed with smaller footprints and greater flexibility.

Inverter-driven heat pumps adjust output in real time to match demand. This improves temperature stability and overall comfort compared to fixed-speed systems. Quiet operation and concealed installation further enhance the occupant experience.

Integrating HVAC Earlier in Design

Builders are increasingly considering HVAC solutions earlier in the design process, not only to enhance performance and aesthetics, but to reduce downstream changes throughout construction.

Solutions such as Midea’s EVOX platform reflect this design shift. As projects become more space-constrained, early integration will only continue to play a larger role in multifamily design and tenant satisfaction.
