CAPEX PHASE OPEX PHASE
•Reduce Equipment Costs •Improve Operations
•Reduce Installation Costs •Improve response times
•Reduce Installation Times •Improve efficiencies
•Reduce Risk •Reduce Complaints

5. Common User Interface
A B C D E
OR A B C D E
Focus is on ensuring the user has the most appropriate information in a format that is quickly
understandable
Data can be from anywhere – from any system
● Format is consistent
● Less different types of user interface = lower software, maintenance and training costs
● Improved comprehension = faster reaction to events
● Easy to manage users

6. The Power of Cause and Effects
> Fast first level response
> Fast pinpointing of source of alert
> Improved diagnosis
> Improved efficiency of operation

7. Use of Open Standards
• Fundamental to an integrated solution
• Allows differing systems from different
manufacturers to communicate
• Can be put out to competitive bidding
• Makes upgrading and enhancements
easier
• Less reliance on third party technical
support

8. What are the Challenges?
> Determining what you really want
> Developing a specification
> Having a platform that is future proofed
> Keeping it simple
> Meeting cost constraints
> Getting Best Value
> Getting Best in Class
> Not being “tied in” for future extensions and operational support
> Not getting tied into details that compromise cost and functionality
> Construction chain maximising their opportunity at your expense

9. How can an Intelligent Building be
Achieved?
Have a clear vision…
• Understand legislative restrictions and opportunities
• Determine a functional vision
• Get buy-in from all parties
Engage experienced expertise early…
• Find partners who you can trust
• Develop detail designs early to ensure viability
• Establish true costs to deliver and run the project
Stay engaged…
• Through both Construction and Operational phases
• Don’t let intermediaries compromise the vision
• Get the right team involved

Editor's Notes
1 – shows silo systems. Typical of most systems installed.2 – shows a basic int. system, but still a half-way house; siloed systems with a single head-end probably represent the most expensive implementation. Still have the single-system delivery/engineering, but now with the additional integration element. This is what most integrated solution are and why integration is considered more expensive. Although it does provide a single front end, often represents limited capability, not very robust whilst relying on power of PC.3 – moving to common backbone – usually IP enabling a more robust functional int. – however still siloed in its implementation – represents most common form of int. today4 – lighting into BMS - see this more today with the KNX solutions5 – finally full int. by zone. Today’s systems capable but often only partly implemented due to procurement, standards & capability6 – examples of other systems that link at the management level – server to server. Usually only implemented when specific function required – not just for a common user interface.
1 – this is the typical siloed solution, with multiple individual front ends2 – single user front end across multiple systems3 – focus only on appropriate info – that can be quickly understood4 – since the data can come from anywhere – any system - the format of the user interface must be consistent – whether it is web interfaces or main workstations - fewer user interfaces reduces s/w costs, maintenance & training - improved understanding of the system – which leads to faster response to events - easier to manage multiple users and what restrictions they have
1 – here is a simple scenario – in the event of a fire detection, a number of reactions can automatically be effected - display on a dynamic graphic to locate the event - drive the cctv camera to set presets, record pre and post event, and display live view on a monitor - over ride HVAC plant – put extract air systems into fire mode – usually this is hardwired - open nominated doors automatically – save people from using breakglasses - set lighting to fire statusWithout an intelligent int. system it is not possible to achieve this sort of C&E in a cost effective manner, and certainly not possible to make changes to the functionality in the future easily.It also provides fast level of response – much can be automatedFast pinpointing of sourceImproved diagnosis – full audit trail of the event with video footageAnd obviously improved efficiency of operation – this is a real driver for int. in retail shopping centres
1 – shows levels of a BMS, as basically defined by the ISO standards - mgmt level – typically IP where enterprise servers and workstations reside - automation level – where nc/rc reside, and local wks - field level – typically field bus RS485 or similar – connects local controllers, field devices – drives, sensors, actuators2 – these are the different types of common open protocols these provide means of integration for intelligent functional solutions, but not one meets all needs - so BACnetrecognised as good for HVAC primary plant, although it functions across all layers - LON good for sophisticated life space control – temperature, lighting control - KNX good for basic life space control, especially focused on lighting control - Modbus good for any int. to electrical systems – power distribution etcWhere as OPC, XML & SOAP are all methods to int. at the mgmt levelSo a combination of open protocols is usually needed along with a capability to int. bespoke protocols (common in the security arena).
1 – don’t just ask for int. – its lazy and you will get an over expensive response – companies trying to manage risk2 – develop a spec that defines exactly what C&E you want3 – define a platform that is still going to be here tomorrow – many s/w solution out there that have no real future development and often limited in their real capability4 – don’t specify functionality that requires significant cost – just for the sake of wanting to be different5 – if it doesn’t meet cost constraints, the construction chain will soon spot it and take advantage6 – will be challenged if you specify against a certain product7 – getting best in class not easy – time consuming and can challenge program time – but is usually worth the investigation8 – open protocols do not ensure not being tied in. Selecting product with multiple channels does9 – don’t spec a protocol or integration method – it limits the potential solutions10 – the hidden cost. They normally want to keep the packages siloed – this ruins any chance of functional int. being achieved – most M&E contractors do not like the packages being combined as this gives critical mass to the specialist – the main contractor can then procure direct with the specialist
