1. Intelligent Buildings in Refit Situations Adapting Today’s Workplace for Tomorrow’s Worker Dan Seth, P. Eng. Jacques Whitford Environment Limited (JWEL) Ottawa November 21, 2001

2. Some Thoughts to Ponder Do intelligent buildings exist? What level of intelligence do they possess? Is there a market for intelligent buildings? Do intelligent buildings serve a real need? Are they cost effective? Are existing buildings capable of acquiring intelligence? Is intelligent building a fad or a phenomena?

4. What is an Intelligent Building IB Attributes Features Processes Protocol(s) Performance PhD?

5. Paradigm Shift The test of intelligence lies in ‘Performance’, not technology including use of the best materials, concepts and systems to meet the needs of the owner, occupants and the community. It is about ‘Process’ as well as about building and the benefits lie in economy and flexibility to meet the working and sustainability needs.

6. Definition An intelligent building achieves and maintains optimum performance by: -automatically responding and adapting to the operational environment and user requirements -facilitating ready and cost-effective adaptation to changes in user requirements, e.g. space configuration and ways of working

7. Definition (cont.) Performance covers: -health, safety, productivity, energy and environmental impact, life cycle cost, marketability Operational environment covers: -climate, occupancy, type of use, services Users are: -occupant, owner, developer and agent

8. What do Customers Want? They do not want technology They want a building that: -works for them and their business -is economical to build and run -responds to their needs -is easy to adapt to new circumstances -is easy to use A building that performs optimally

9. Annual Costs of a Business

11. Obstacles to Success Telco’s Technology vs functionality Capital costs Time to market Size and scale Variable tenant requirements

12. Building Features that Affect IB Performance Shell, core and space layout Amenities Materials and finishes Façade and cladding Structure Environmental systems Mechanical systems Electrical systems IT and communication systems Fire suppression and life safety systems Security systems Sensors and controls

13. Variable Frequency Drives

14. Pump, Fan & Compressor Laws Q 2 / Q 1 = N 2 /N 1 P 2 / P 1 = (N 2 /N 1 ) 2 kW 2 /kW 1 = (N 2 /N 1 ) 3 eg kW 2 = (1200/1800) 3 ; kW 2 = 30% of kW 1 (This translates into a power saving of 70%)

15. Efficiency Measurement Scale

16. Leadership in Energy and Environmental Design (LEED) Criteria: Sustainable sites; Water efficiency; Energy & Atmosphere; Materials & Resources; and Indoor environmental quality Rating System: -Green -Silver -Gold -Platinum

17. IB Performance Criteria Business performance (Serviceability scales) Economic performance Environmental and HVAC System performance Responsiveness (predictive control strategies) Adaptability Ease of use

19. Summary Considering users and their culture are key Innovative technologies must be justified Assessment method(s) for IB’s must be clearly defined and agreed to with the Client Intelligence depends on meeting good practices and not on amassing sophisticated devices Flexibility, Scalability, Maintenance and Commissioning Performance, performance, performance
