Use Your Concrete Structure as a Heating Source

Thermally store Energy in Concrete

The term thermal mass describes the absorption and storage of heat in a building. Concrete and masonry warm and cool slowly and stay warm (or cool) longer than many other building materials. This thermal mass effectively delays and reduces heat transfer through a concrete or masonry wall, resulting in a reduction in total heat loss or gain through the building envelope.
The reduced heat transfer through concrete or masonry is not a heat loss but rather indicates that some of the heat is stored in the concrete and later released back into the room.

Static Pressure in HVAC systems

Ensuring proper duct design in HVAC systems saves money.

It costs money to run a fan.  The harder it has to work, the more money it costs.  If air fans are controlled from a VFD, then slower speeds also mean less noise.  There are lots of advantages to paying attention to ductwork.  In most projects is it not even considered.
