Building Systems & Maintenance Flashcards

What is the primary function of an HVAC system?

Answer: Regulate heating & ventilation

The primary function of an HVAC (Heating, Ventilation, and Air Conditioning) system is to regulate the indoor environment of a building. It controls temperature (heating and cooling), humidity, and air quality through ventilation, ensuring comfort and health for occupants. This system is critical for maintaining a productive and safe indoor climate.

Which system is responsible for water distribution in a building?

Answer: Plumbing system

The plumbing system is specifically responsible for the distribution of water throughout a building. This includes bringing fresh, potable water in for various uses (sinks, toilets, showers) and efficiently removing wastewater and sewage. A well-maintained plumbing system is essential for hygiene, sanitation, and the overall functionality of a facility.

What type of maintenance aims to prevent equipment failure?

Answer: Preventive maintenance

Preventive maintenance is a proactive approach designed to prevent equipment failure before it occurs. It involves scheduled inspections, servicing, and repairs based on time or usage, rather than waiting for a breakdown. This strategy helps extend the lifespan of assets, reduces costly emergency repairs, and ensures continuous operation.

Which device detects smoke or fire in buildings?

Answer: Smoke detector

A smoke detector is a crucial safety device specifically designed to detect the presence of smoke or fire in buildings. By sensing smoke particles, it triggers an alarm, providing early warning to occupants. This early detection is vital for enabling timely evacuation and minimizing potential damage or loss of life.

What is the purpose of a building automation system (BAS)?

Answer: Automate and optimize systems

The purpose of a Building Automation System (BAS) is to automate and optimize the operation of a building's various mechanical and electrical systems. It integrates controls for HVAC, lighting, security, and other services, allowing for centralized monitoring and management. This leads to improved energy efficiency, reduced operational costs, and enhanced occupant comfort.

Which system controls electrical power distribution?

Answer: Electrical system

The electrical system is the core infrastructure responsible for controlling and distributing electrical power throughout a building. It safely delivers electricity from the utility grid to all outlets, lighting fixtures, machinery, and other powered systems. Proper functioning of the electrical system is fundamental for a building's operation and safety.

What is corrective maintenance?

Answer: Repair after failure

Corrective maintenance is a reactive maintenance strategy performed only after equipment has failed or malfunctioned. Its primary goal is to repair the broken equipment to restore it to its operational state. While sometimes unavoidable, relying solely on corrective maintenance can lead to unexpected downtime and higher repair costs compared to preventive approaches.

Why is regular inspection important in maintenance?

Answer: Detects problems early

Regular inspection is paramount in maintenance because it allows for the early detection of potential problems, wear, or damage before they escalate into major failures. By identifying issues proactively, facilities can schedule repairs or replacements at convenient times, preventing costly downtime and extending the lifespan of equipment. This proactive approach saves time and resources in the long run.

What role does documentation play in maintenance?

Answer: Tracks repairs and schedules

Documentation plays a critical role in maintenance by providing a comprehensive record of all activities, including repairs, inspections, and scheduled servicing. This historical data helps facilities track equipment performance, identify recurring issues, and plan future maintenance schedules more effectively. Good documentation is essential for budgeting, compliance, and efficient troubleshooting.
