n is Principal and the founder of The Hartman Company, a technology devel=
opment and applications firm that works with designers, manufacturers and=
 end users to apply emerging ultra-efficient HVAC and lighting technologi=
es. Among the most notable of Mr. Hartman=92s developments have been the =
=93Equal Marginal Performance Principle=94 and relational control concept=
s. These provide new approaches to integrating variable speed and other n=
ew HVAC/Lighting technologies with network controls for simpler, lower co=
st and better performing building comfort systems. =0D=0ATom Hartman hold=
s a number of patents for advanced technologies and works worldwide with =
manufacturing and engineering partners to develop sound, cost effective p=
roducts and designs that utilize these technologies for a wide variety of=
 applications. In addition to the development of the Equal Marginal Perfo=
rmance Principle and relational control, Hartman has developed and works =
to apply a number of other indoor comfort enhancing technologies. Tom cur=
rently serves as an editorial advisor to Heating, Piping and Air Conditio=
ning Magazine and the on-line publication, automatedbuildings.com. Tom is=
 also a member of ASHRAE SSPC 55 and lectures and writes about comfort an=
d energy issues for major symposiums and periodicals all over the world.=
=0D=0AProgram: Relational Control: HVAC System Control for the 21st Centu=
ry=0D=0ACombining variable speed and digital network technologies provide=
 new and exciting energy efficiency enhancing opportunities with what are=
 called =93relational control=94 techniques. Relational control employs t=
he network capacity of modern DDC systems to operate each HVAC component =
in accordance with system requirements and in an=0D=0Aoptimal relationshi=
p to the current operation of all other system components. Relational con=
trol techniques offer dramatic improvements in energy efficiency, stabili=
ty and system performance. This new family of control strategies represen=
ts a significant change from the stand alone nature of PID control that i=
s still widely employed today. But this newer technology requires new ind=
ustry process and practices to achieve success in implementation. So when=
 relational control techniques are applied to achieve ultra-efficient sys=
tem performance, the process through which it is applied needs to be chan=
ged as well to be certain the technologies are adequately supported and e=
nd up operating as expected.=0D=0AThere are currently two primary categor=
ies of relational control as applied to HVAC systems. Demand based contro=
l, which is derived from the Equal Marginal Performance Principle, is emp=
loyed to optimize the operation of systems that are composed of multiple =
power consuming components such as central systems. Intelligent iterative=
 control is employed to improve the efficiency and performance of systems=
 that distribute a resource such as heating, cooling or airflow to multip=
le zones. =0D=0AThis discussion will provide an introduction to these new=
 relational control technologies and outline their advantages over curren=
t control practice. It will also discuss the application of these technol=
ogies to actual building systems and outline the types of changes in the =
design / construction / startup processes that are necessary to ensure ap=
plications of these newer technologies achieve the projected results.=0D=
