Building Energy System

What is a common characteristic of energy use in conventional buildings?

• Heavy reliance of renewable energy

• Low energy consumption due to passive design

• High dependence on grid electricity and fossil fuels

• Self-sustaining power generation on-site

Which of the following is a typical issue in conventional HVAC systems?

• Automatic optimization with AI sensors

• Zero carbon emissions during operation

• Consistently balanced indoor temperature

• Over-cooling and uneven air distribution

What is the primary function of Building Management Systems (BMS) in grid management?

• To perform billing and energy market trading

• To generate renewable electricity for the utility grid

• To monitor and optimize a building’s internal energy systems and coordinate with the grid

• To control the voltage levels of the national power grid

What is the primary benefit of Microgrids and VPPs for grid management?

• They eliminate the need for DERs.

• They reduce communication between users and the grid.

• They enhance resilience, stability, and enable decentralized renewable energy use.

• They centralize energy control under the utility.

Which factor poses the most direct technical challenge to effective renewable energy integration in buildings?

•  Lack of skilled labour in renewable energy installation.

• Variability of renewable resources such as solar radiation and wind speed.

• High embodied energy in building materials.

• Excessive availability of renewable resources causing grid overload.

Which of the following best explains why combining multiple renewable energy sources is an effective strategy for building integration?

• It ensures a more consistent and reliable energy supply by balancing the variability of individual sources.

• It allows buildings to disconnect completely from the national power grid.

• It eliminates the need for energy storage systems, as all renewable sources produce power continuously.

• It reduces the total installation cost of renewable systems by minimizing component use.

What is the key component in Heat Energy Recovery?

• Heat Exchanger

• HVAC

• Solar Collector

• Fan / Blower

In your opinion, what are some other form of energy that can be recovered in the future?

Which of the following statements about the GEO Building’s energy management system is TRUE?

• It relies on manual scheduling and timer-based control.

• It uses conventional chillers with COP below 3.0.

• Artificial lighting is used for over 80% of operational hours.

• It operates with a fully automated Building Energy Management System (BEMS).

What is one main disadvantage of a Conventional Building Energy System regarding user comfort?

• Uneven temperature control

• High installation cost

• Complex maintenance

• Intermittent power output
