If you had to do it again?
The HVAC system could be simpler to achieve the same result
Building users opinion
An indoor environment satisfaction and quality oriented survey is carried out, about 60 questionnaire is distributed to the users. 55 feedback regarding to air environment of the office are received, and 71.4% people feel satisfied and normal satisfied about the air quality, 28.5% people feel very unsatisfied. 45 questionnaires is received regarding to indoor environment to work efficiency. 100% people found the current indoor environment promote work efficiency, and 28.58% people feel very satisfied.

Reasons for participating in the competition(s)
This project adopted high performance building envelope system to reduce its energy demand. Underground borehole and solar collectors serves the geothermal heat pumps and absorption chiller as the primary cooling and heating sources. Through smart use of renewable and traditional energy, building heating demand in winter is to be met with zero use of fossil fuel and cooling energy consumption in summer to be reduced by 50%.Various building sensors and metering devices were installed to collect real-time operational data, providing data monitoring, analysis, and control improvement, with aid of EMS and BMS, to realize optimized operation and maximized energy conservation.
