Building Information Modelling or “BIM” is becoming a critical part of facility management operations ensuring best practice for effective long term record keeping for commercial buildings.
Building Information Modelling, as a generalization, will often begin at the design stage of a building while an asset register is often referred to for a part of an existing operational building.
As a general comment, we would say Building Information Modelling is deeper, and a “cradle to grave” strategy, that is, BIM starts, with the design and construction consultants, whom choose or recommend materials and services to be implemented into a site.
As an asset register might target the lighting, electrical or HVAC system only or a monetary value, such as recording only asset above a set approximated value, say $3000.
Both situation are relevant as the Building Management System can trend data which serves to offer opportunities for operational management and energy conservation.
They can share information creating a relevant and “live” data base for the connected equipment to the BMS.
Via trend logging the data from the equipment connected either via a Original Equipment Manufacturer High Level Interface or third party external sensors.
Chiller installed on Day, cost $850,000 including peripherals such as pumps, mechanical electrical switchboard, cooling tower and so forth.
The BMS controls and monitors the chiller via high Level interface and via external third party sensors.
There are various parameters measured and recorded for the chiller including energy, temperatures, pressures, alarms, faults, all building a picture.
The BMS data and the BIM information can be analyzed, what do we see?
Repeat faults, energy performance, external factors, just to name a few.
Does the site have a fluctuating voltage making the chiller work harder, can this be rectified, is there a power correction unit involved?
Are there further opportunities for adjustments and recommissioning to maximize the equipment and the energy being used?
We appreciate the sub-heading of “software Integration” sounds deep and meaningful and rather expensive, but, its not. In a nutshell, picture a favorite excel spread sheet, in that spread sheet you want to move “cell” of information into another, yet related spreadsheet, it’s a quick couple of clicks and your information is there in the second spread sheet.
Software integration between the two is not much different, there are of course idiosyncrasies which need to be understood, but form a client’s perspective, this know ledge is not required. The point is that once the system foundations are set up, integration is straight forward.
How do we use the information available?
Here are just a few examples:
Its is 7:00am on a Monday,
An Alarm is generated by the vertical rise system
The alarm data is logged in the BMS
The BMS sends an email to the building manager and the elevator company
The Building manager sees the email, logs on the system for his mobile, and confirms a work order which is sent to the elevator company.
With the confirmation of the work order, a bulk email is sent to tenants notifying them an elevator is out of order and to accommodate the inconvenience.
The Building manager gets of the train at 7:45am and attends site.
no panic, and the tenants are aware.
The building Manager gets his coffee and puts a pedestal sign in the lift lobby for visitors that elevator number X is out of order.
Often with the Variable speed drive applications the energy savings will reflect in the Nabers assessment, this in turn has the opportunity to make the landlord money as the building becomes more and more “green”, which in turn will eventually add opportunity to improve the relationship with tenants and income opportunities.
