Hey Tim good discussion topic.
It certainly would be an interesting financial analysis comparing the cost of cloud based service versus a well delivered and managed BMS system and or the wired vs wireless solution. The issues we see appear to be predominantly caused by poorly engineered and commissioned systems coupled with maintenance contracts that do not add value.
Using wireless sensors and other low cost sensing technologies technologies helps with initial capital cost but does not address the poor engineering and commissioning practices. Whilst I agree the sensing costs have dropped dramatically the financial model needs to take into account the fact that a wired point can last 30 plus years.
Looking forward to the webinar
