In the article "The Expanding Role of Sensor in "Smart' HVAC Systems" Manz (2018), expresses the need for sensors in buildings as it will "reap significant energy savings". He explained that by connecting all the various systems in the building, especially the HVAC system, will create an integrated and innovative monitoring software that observes the energy consumption of the building. Manz mentioned that over the years building owners neglected energy savings until the 1970s and 2000s when there was an increase in oil prices making "power conservation is essential". Another aspect of the need for sensor technology is the advancement of technology. Replacing the analogue sensor with a small-scale digital unit reduces installation time and "eliminate the need for recalibration". With the points explained in the article, Manz could have elaborated on the overall cost of the sensors.
Firstly, tenants may not be willing to spend
additional costs for upgrades. According to the U.S Department of Energy, the
"split-incentive" refers to the accumulation costs and
energy-efficient advantages to various bodies based on the responsibilities for
capital improvements and other bills, such as utilities. An example of the
"split-incentive", a building owner would like to replace the
fluorescent lights to a LED motion sensor light that will cost $20 000 in
total. Some tenants are willing to accept this proposal as it will reduce their
utility cost but some tenants may refuse. It may be due to their lease period
is shorter than the breakeven savings cost which could be 10 years later. With
the implementation of these "smart" systems, there would be an
increase in their rentals.
