Less frequent El Nino events is not a phenomenon related to global warming. Global warming refers to the long-term increase in the Earth's average temperature, which is supported by the fact that the Earth's temperature is increasing. The reduction of ice in the Arctic sea and the bleaching of coral reefs are also consequences of global warming. However, El Nino events are not directly linked to global warming. El Nino is a natural climate pattern that occurs irregularly in the tropical Pacific Ocean and affects weather patterns globally. While global warming may influence the intensity of El Nino events, it does not directly cause them or make them less frequent.

Natural gas is not a renewable source of energy because it is a fossil fuel that is formed from the remains of ancient plants and animals. It is a finite resource that takes millions of years to form, and once it is depleted, it cannot be replenished within a human timescale. In contrast, the sun, wind, and tidal energy are considered renewable sources because they are naturally replenished and will not run out in the foreseeable future.

During the planning and design stages of a building, technology can be used in multiple ways. Firstly, software can be used to simulate how people will use the facilities and open spaces in and around the building. This allows the architect to optimize land use and create a more efficient design. Additionally, 3-D software can be utilized to design the building, making it easier for all parties involved to understand the design. This visual representation helps in better communication and collaboration among architects, engineers, and clients. Therefore, the correct answer is 1 and 2 only.

The correct answer is that an occupancy (motion) sensor works by detecting changes in infra-red energy (body heat of the occupant) within the coverage area. It operates by the "line of sight" principle. This means that the sensor can detect the presence of a person by sensing the heat they emit and can determine their movement within the sensor's range. This method is commonly used in motion sensors to detect occupancy in rooms and trigger actions such as turning on lights or adjusting temperature settings.
