   <li><strong>Dual-duct with terminal heating (DDTH):</strong> Two separate variable volume supply air streams. Ones with tempered air, and one with cool air, typically around 55&deg;F. A mixing box just upstream of a lab's supply diffusers will adjust airflows from these two air streams based on the space temperature. More cold air will be used as the cooling load in the space increases. DDTH system can be more expensive than other system options and therefore are seldom used.</li>
