4.4 Step 4 – Project Completion
4.4.1 Importance of Testing and Commissioning
Proper testing and commissioning is one of the most cost-effective means of
improving energy efficiency and the indoor environmental quality of school
buildings. Systems that function properly often consume less energy, experience
less down time, and require less maintenance, thereby saving money for
schools. Other benefits include:
• Proper and efficient equipment operation;
• Improved indoor air quality, which can increase occupants’ comfort and
productivity;
• Reduced health hazards related to indoor air quality and respiratory illness;
and
• Fewer complaints received by occupants and on warranty issues.
4.4.2 Performance Monitor
In order to ensure that the schools’ expectations for
green facilities aremet, it is suggested that professionals
and contractors are employed to monitor performance.
Items that should be monitored include:
• Electricity/gas consumption (e.g. air conditioning,
lighting, hot water system, lift, shading device,
window film, timer/daylight/occupancy control of
lighting);
• Electricity generation (e.g. wind turbine, PV panel);
• Water consumption (e.g. tap, urinal, water closet, irrigation system, recycling
rainwater and domestic wastewater);
• Temperature fluctuation (e.g. green roof, window film, shading device);
• Indoor air quality (e.g. fresh air provision, low VOC content furnishing); and
• Staff and students opinion surveys (e.g. thermal comfort, daylight appearance,
lighting quality, staff/student performance).
