Abstract

Energy efficiency and carbon reduction of new buildings are key objectives of policies that aim to decrease electric use nationwide, particularly during the summer, when electricity usage is at its highest. A case study was developed to test the energy-conservation performance and economic feasibility of the creative and intelligent open building “MEGA House”. MEGA House focuses on making improvements in four key areas: (a) Material, (b) Electronic, (c) Green Building, and (d) Automation. This paper focuses on applications in the areas of Electronic and Green Building. The economic analysis in this paper of electricity consumption and of the potential energy-savings is based on the use of energy conservation equipment such as earth tubes and solar chimneys, situation simulations, field measurements at four experimental stages, and economic calculations. According to the results of measurement and economic analysis, the MEGA House demonstrated optimal energy conservation performance. Using an earth tube (fan) and a solar chimney (exhaust fans) in the MEGA House lowered the indoor temperature about 1~2
C in summer, while using an earth tube (fan) instead of an electric heater increased the indoor temperature as much as 3e4
C. In terms of economic benefits, the using the energy-conservation facilities installed in MEGA House reduced electricity expenditures by NT$8537.76 and decreased CO2 emissions by around 1288.83 kg per year

5. Conclusions

The scope of the present paper is limited to the creative and intelligent open building “MEGA House”. We analyzed the power consumption and CO2 emissions related to the use of the energysaving facilities that were installed in MEGA House. Because the use of the air-conditioners used more power than the minimum requirements for the building during the summer, a four-stage experiment was set up to simulate, measure, and assess the economic efficiency and the potential for conserving energy. This section summarizes the research procedures used and the results obtained, with conclusions as follows: 1. The energy conservation facilities in MEGA House hold the strong potential to enhance the energy conservation efficiency of “green” buildings. 2. The energy conservation performance achieved by activating an earth tube fan and solar chimney exhaust fans 1 h prior to residents returning home in MEGA House in order to lower the indoor temperature is better than the performance achieved by using air-conditioners.
