Issues Related to Intelligent Buildings

1

IB technologies are expensive …

• Intelligent building technology typically pay for themselves.

investments

• Return of investment within one or two years

• Delivering energy savings and other operational efficiencies.

• Some building management programs have generated a positive return on investment within several months.

Intelligent buildings are for certain building type ..

• Office buildings • Residential buildings (Intelligent House Index) • Educational buildings

• Hospitals • Banks • Sports centers

• Etc. It is about features and benefits of intelligence rather than building typology.

Intelligence are for new buildings…

• Existing building have the opportunity to experience architectural intelligence.

• Building management and IT systems to optimize system performance and simplify facility operations.

• Wireless technology made it easier for traditional buildings to transform into intelligent ones.

• Examples of transforming buildings are many.

• 311 South Wacker, Chicago, is an example.

Intelligence are for new buildings…

311 South Wacker, Chicago, USA • South Wacker installed a state-of-the-art energy saving system and LED lighting

• South Wacker is the first major office tower in Chicago to install wireless Pneumatic thermostats connected to a cloud-based intelligent building system.

• A total of 944 thermostats were installed.

Intelligence are for new buildings…

311 South Wacker, Chicago, USA • The system utilizes real time data to make operational energy saving decisions.

• Many environmental improvements.

• The property saved about 2.1 million kWh per year which is the equivalent of planting 37,130 new trees.

• The building earned this substantial award for the West Loop office tower.

5

Intelligent buildings are not attractive to tenants..

“We shape our buildings, and afterwards our buildings shape us” Winston Churchill • IBs are argued to: • improve energy efficiency, • reduce cost, and • improve productivity

• Therefore, they are valuable to tenants.

• Numerous studies and surveys showed IBs to be more attractive compared with traditional buildings.

6

Intelligent buildings are complicated to operate..

• Self-know, self-decide and self-respond.

• Intelligent building management system is often easier to operate and maintain than a building that lacks automated systems.

• Integration.

• Communication (e.g. dashboards, alarms, etc.)

• Problem self diagnosis.

• Minimum human intervention

Intelligent buildings might promote losing jobs..

• Minimum human intervention • Less employment for operation • 5 to 7.1 million jobs will be lost due to automation (in the richest countries) in the next 5 years.

• 4 out of 10 Canadians might lose their jobs due to technologies in the next 10-20 years.

• Employment shift
