Efficient HVAC Control System Using Sensors and Computers to Save Energy in Buildings

This proposal suggests using sensors and computers to regulate HVAC systems by detecting human presence in offices and adjusting the system accordingly. While the idea may reduce electricity consumption, the ethical dilemma arises from potential excessive costs and equipment wear and tear. The involvement of researchers, office workers, and investors brings varied perspectives on the proposed solution. Although the ACM Code guidelines support seeking peer review and critical evaluation, the decision whether to implement this system lies in carefully weighing the benefits and drawbacks in terms of cost-effectiveness and energy efficiency.

  1. The Dime You Save Will Cost $1. Using Computers and Sensorsto Curb Electricity Use in Buildings UC San Diego Computer Scientists Propose Novel Solution to Reduce HVAC Power Consumption April 13, 2011 By Doug Ramsey

  2. The Dime You Save Will Cost $1. • What is proposed: • Using sensors and computers to control HVAC systems. • How Will it Work? • Deploying sensors and switches to each office to detect human presence. • Upon detecting no human presence, it will turn the HVAC system off. • What Equipment is needed: • Thermostat • PIR Sensor • Reed Switch • Wireless module • Sheeva Plug Base Station

  3. The Dime You Save Will Cost $1. • Ethical Issue: • Is it right to try to spend research dollars on something that will cost too much to improve the process. • The process is not good on HVAC equipment. Constantly starting and stopping equipment will wear it out faster • Separate HVAC units required. • People involved: • Researchers-would of course love to see this work • Office workers- worried that their tax dollars are being wasted • Investors- want a return on their investment • Possible Outcomes: • Failure: money wasted on research • Success: money saved. Investors happy • Solution combined with existing methods and streamlined

  4. The Dime You Save Will Cost $1. • What I would Choose: • I would actually choose to not implement the new system just for the fact that the amount of equipment necessary and the wear and tear of that equipment . Also the money spent will outweigh the money saved. • What does the ACM Code say? • This is covered under the More Specific Professional Responsibilities • 2-4 Accept and provide appropriate professional review • Whenever appropriate, individual members should seek and utilize peer review as well as provide critical review of the work of others (Barger)

  5. The Dime You Save Will Cost $1. • Conclusion: • Although the Ethical issue is not blatant and screams injustice, there is still evidence that the researchers may not be acting in the best interests of the public who use the building.
