New building engineer. 40 yr old building. All orginal equipment. Three Dunham-Bush AHU 35 ton@. 8 Trane AHU 30-100 tons. Two Clever-Brooks 70HP steam boilers. Two small Weil Mclain hot water boilers. Where would you start in replaceing this equipment?

Lots of money. Single or multiple story building? I,ve replaced entire systems similar to yours with RTUs in single story buildings, worked out great especially if you lease out space. If all the components of the steam system such as water coils, radiators, controls are in bad shape you may want to start there and then procede with replacing major components. I'm not an engineer but I would imagine one of our main concerns is energy savings. There is alot of information available through university extension services in every state concerning utilizing new technical advancements especially in the controls and components such as ddc and vfds. In what order this should be approched would depend if the building is occupied or not, obviously you won't jerk the boilers out in the middle of the winter. I'm sorry but the information you provided is a little sketchy to point you in a definate direction.:confused:

Multiple story building, three stories. The building is occupied, also is owned not leased. The steam boilers, which are run at 5 psi runs to four heat exchangers in the same room. My DDS is a Honeyweel 1000. I think you need to be retired to know what that is, LOL. I have a few vfds.
