Energy Saving For Buildings using Occupancy Sensory System

Project Title

Energy Saving For Buildings using Occupancy Sensory System

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

There is a significant amount of energy is consumed in the university buildings. This consumption includes lecture rooms, laboratories, offices, and dormitories of the university buildings. The university classes are held on a daily basis and offices are occupied as well on regular basis. The consumption is recorded for both winter and summer seasons. It was considered that there is no energy saving mechanism is installed at our university.

In this project, we proposed an energy-saving management system using an occupancy sensor system that will save energy in all four seasons. It is expected to save more than 30% of energy via adopting this proposed system in the Electronic department only. The proposed project saves energy by detecting the presence of people in terms of temperature, heat, and motion detection, in addition with the usage of the photo-electric sensor the more focus on the presence of people can be acquired using the light parameter.  If the presence of one or more than one person is detected using the proposed occupancy sensor-based system the lights will be in usage. If there is no detection of the people is recorded via the proposed occupancy sensor-based system the lights will be turned off automatically. This will save the energy that is wasted in the department of Electronic Engineering, QUEST Nawabshah at from lecture rooms, laboratories, and offices. It is expected that the proposed project will save more than 30% of the energy that is wasted before implementing this proposed occupancy sensor-based system.

Project Objectives

The aim of the project is to develop an energy-saving system using an occupancy sensor-based system.  The project has the following objectives.

1. Calculate the energy consumption on a daily basis for the department before implementing the proposed system
2. To implement the proposed occupancy sensor-based system for energy management
3. Compare the energy consumption before and after implementing the proposed occupancy sensor-based system
4. To design a prototype for energy-saving system based on an occupancy sensor system

Project Implementation Method

The energy-saving of university buildings will be implemented using an occupancy sensor-based system. The occupancy sensor-based system included Movement- and photo-sensors, timers and other smart technology that can be used to adjust the lighting to conditions outside, when you are away, and to manage overall operating hours. Motion sensors and other features will be the key techniques to cut electricity use and address inefficient and unnecessary lighting in and around the department. They rely on three motion-sensitive techniques to detect presence due to Passive infrared (PIR), Ultrasonic detection, Microwave detection.

In the first step, the daily energy consumption of the department including classrooms, labs, and offices will be recorded. In the second step, the occupancy sensor-based system will be implemented on the main electricity of the department, and that will turn-on light if the presence of a person is there. The system will turn off lights automatically if there is no presence is detected. In the last step, the energy consumption will be compared before and after implementing the occupancy sensor-based system as shown in Figure 1.

Figure 1. Proposed Implementation Model of the project.

The proposed project occupancy sensor-based system for energy saving will be a completely new lighting installation, bearing in mind the future operational costs of the installation. The project will be considered the long-term benefits of replacing light systems as part of other planned refurbishments, which could remove existing constraints such as ceiling type or height, space, layout for improved future gain. Figure 2 determines the project design methodology and implementation location in the classroom as an example and likely, the occupancy sensor-based system will be installed all over the department in order to save more and more energy. Figure 2 defines that all the main lights will be connected to an occupancy sensor-based system along with a relay and other necessary equipment to protect the components and other things in the system. The occupancy sensor-based system also requires the dc power to run but that power is minimal and using the proposed occupancy sensor-based system the energy saving can be reached up to 30%.

Benefits of the Project

The benefits of proposed Energy Saving using the proposed occupancy sensor-based system are defined as;

• Making lighting energy efficient can help the department to achieve significant savings.

• Luminaires (e.g. checking that the light is well diffused)
• Lighting controls (e.g. installing sensors for better lighting management)
• Lighting design (e.g. over-lighting a space, or leaving lights on unnecessarily)
• The project has potential longer-term gains of a full overhaul.

Technical Details of Final Deliverable

The project will deliver the prototype that will save energy using the proposed occupancy sensor-based system for the department of university as the final deliverable. The energy consumption will be calculated first and after that, the mainline will be linked with the proposed Energy Saving using the proposed occupancy sensor-based system that will save the energy and system. Finally, the comparison of energy consumption will be demonstrated in order to show the performance of the proposed Energy Saving using the proposed occupancy sensor-based system.
