Smart City IoT development project should not be limited to benefiting a selected few and determined by demographics, race, or affordance. Multiple beneficiaries should be observed.

Smart City – IoT Development

 Smart cities as urban innovation and transformation initiatives aim to harness physical infrastructures, ICT, knowledge resources, and social infrastructure for economic regeneration, social cohesion, better city administration, and infrastructure management (Ojo et al. 2014).  Specifically, smart cities are concerned with the transformation of life and work of city inhabitants (Hollands 2008).

 Example  of  Living  room  AC  &  FAN  profile

Going to bed at 11:00 pm, the temperature is initially preset to 24C (by profile)

Body temperature is reduced during deep sleep (a.k.a REM sleep) and the A/C temperature is raised to 26C (by sensor)

1 hour before waking up or depends on room temperature, A/C is switched off and a tower fan is switched on instead (by schedule)

Integrating with sensors through API

Our IoT product could adjust the temperature according to sleeping pattern such as deep sleep or data collected from other wearable devices

Harvard Medical School Division of Sleep Medicine asserts that our body temperature is reduced 1 to 2 F during sleep and during REM sleep, our body temperature will fall to its lowest point. http://healthysleep.med.harvard.edu/healthy/science/what/characteristic

Total energy saving for night use case 12 hour in %: ∑ = A (3%) + B(0%) + C (3%) + D (95%) = ~ 10 % Save in electricity

Details = ((4*(1-3%) + 3*100% + 4*(1-3%) + 1*(1-95%))hr /12 hr = 10 % (save in electricity)

For every 1 deg C increase in temperature setting, the reduction of electricity consumption in the air-conditioning equipment is about ~3%. (EMSD, Energy Efficiency guide)

A Taiwanese research report has successfully proven that cost-savings in electricity could be achieved by using a smart IR Remote Control System - Up to NT$10,000 saving could be achieved Wu, Y. C., Chen, M. J., Chang, B. S., & Tsai, M. T. (2014). A low-cost web-based infrared remote control system for energy management of aggregated air conditioners. Energy and Buildings, 72, 24-30.

Estimated Cost Savings

An incentive plan could be devised by utilities company. Similar case has been adopted by California’s Pacific Gas & Electric Company – and subsidizing a one-time USD$ 50 for installation of a smart metering and control device.

Our  IoT  product  could  easily  achieve  10%  of  cost  savings  and  more  cost  savings  (e.g.  20%)  could  be  achieved  if  the  device  perform  extra  rouBnes
