Active Design Strategy

Which of the following is the primary goal of active design strategies in green buildings?

• To maximize natural ventilation through architectural orientation

• To reduce energy use through passive means only

• To integrate mechanical and electrical systems that optimize energy performance

• To enhance aesthetic design features in the building façade

What is the primary factor influencing the performance of a rooftop solar PV system?

• Building envelope insulation

• Indoor lighting control system

• Roof orientation and tilt angle relative to the sun

• Type of window glazing used

A building-integrated photovoltaic (BIPV) system differs from traditional rooftop PV systems in that:

• It is installed on separate land areas outside the building

• It is a temporary installation during construction

• It is integrated into building elements like façades, roofs, or canopies

• It does not generate electricity

What is the function of a Building Management System (BMS) in the context of active green design?

• Managing daylighting through fixed louver systems

• Monitoring and optimizing performance of mechanical systems in real-time

• Designing energy-efficient building envelopes

• Regulating solar gain through building orientation

In tropical regions like Singapore, what is a key design consideration for integrating solar PV panels into buildings?

• Maximize vertical mounting for evening sun

• Ensure panels face north with minimal tilt

• Balance between solar exposure and roof ventilation to prevent overheating

• Avoid placing panels near vegetated roofs

Which of the following best illustrates the synergy between active and passive strategies in a green building?

• Using automated blinds with natural ventilation only

• Installing solar panels without considering building orientation

• Combining daylight sensors with artificial lighting controls

• Designing thick walls with no mechanical intervention

Which active water efficiency strategy is most appropriate for a green building aiming for high sustainability certification?

• Installing large cisterns for rainwater harvesting

• Using drought-tolerant native plants

• Deploying smart sensors for real-time leak detection and flow regulation

• Designing sloped surfaces for natural drainage

In the context of smart buildings, how do occupancy sensors support active energy-saving strategies?

• By alerting security to the presence of people

• By increasing ventilation to unoccupied rooms

• By automatically adjusting lighting and HVAC systems based on presence

• By blocking daylight in unused spaces

Which of the following best explains how a heat recovery system contributes to energy efficiency in green buildings?

• It absorbs solar radiation to heat incoming air during the day

• It reduces the cooling load by recycling waste heat from exhaust air to pre-condition incoming fresh air

• It uses thermal mass in building materials to retain internal heat

• It eliminates the need for insulation by maintaining constant indoor temperatures

Which of the following artificial lighting strategies most effectively contributes to energy efficiency in a green building?

• Using high-wattage incandescent bulbs with dimmer switches

• Installing LED lighting with daylight and occupancy sensors for automated control

• Relying on fluorescent tubes controlled manually by building occupants

• Increasing the number of fixtures to reduce shadows and enhance brightness
