Initial Cost vs Life Cycle Cost in BMS Related Projects
In this episode Clay, Nick, and Mark discuss cost considerations with new or retrofit BMS related projects, specifically initial cost compared to lifecycle cost. A key part of this process is accurately projecting the life cycle costs associated with the proposed project and comparing different options with Net Present Value (NPV). Our team of experts discusses how to generate a cash flow diagram and why NPV is so valuable in determining the financial impacts of different options within a project. We also discuss that although one option may seem better than others with NPV, there are many other things to consider and ultimately it us up to the owner to decide. This is a very engaging and relatable discussion on cost considerations, tune in for a great discussion!

IT Challenges with Large Scale Integrations
Mark, Clay, and Rich discuss the various IT challenges with large scale BMS integrations. Often times the IT network is overlooked in BMS network design, this can pose many challenges throughout a project and for many years after a project. Some key takeaways of this episode are that the IT network needs to be properly managed and maintained including regular updates and backups. If at all possible ample capacity should be designed in the IT network during a large scale integration project to provide room for growth in the future and redundancy if there are any problems down the road.

The Evolution of Building Management Systems
Mark, Clayton, and Rich discuss the evolution of the building management system. Our subject matter experts Mark and Rich discuss the BMS industry and the drastic changes they have seen in their lifetimes. We start off the podcast with the concept of temperature control dating back to the 1600's by a chicken farmer named Cornelius Drebble. Much can be learned from the craftsmen, engineers and techs from the early days of building controls. The need for correct application of P, PI, and PID control, reset calculations and control loop tuning are often ignored, but essential to produce high performing buildings and systems. Throughout the episode we cover topics such as the rise and fall of pneumatic controls, the birth of direct digital controls, the inception of BACnet by the founder Mike Newman, and how open protocols have changed the BMS industry.
