An energy audit conducted on a building is also known as a building energy assessment. It can summarise the whole idea of a building’s energy use. Conducting an audit can help business owners determine how much energy a building uses and how much of this energy is useful. It also determines where it is losing energy and which problem areas and fixes should prioritized to make the building more efficient and comfortable. An energy audit should be the first step before making and energy-saving improvements. A targeted audit was conducted on the selected hostel building to identify the energy management opportunities and possible implementation of energy efficiency retrofit techniques. Regression and CUSUM analysis were performed on the obtained data to study the pattern of energy consumption. Recommendations were made on the energy management opportunities for energy conversation and saving with the estimation of carbon footprint.
The demand for electricity in Malaysia is growing yearly. Renewable energy from the sea waves is one of the solutions to solve the energy crisis in Malaysia. Malaysia has a long coastline of 4,675 kilometres. Therefore, simulating a sea waves power plant for Malaysia is an interest of this study. This research is aim to identify the suitable locations for installing sea waves power plants in Malaysia and to simulate the total power generated by the sea waves power plant by using Hybrid Optimization Model for Multiple Energy Resources (HOMER). HOMER is a power optimization software and it is used to simulate and analyze the sea waves power plant in the generation system. The sea wave height, the period, and the water depth are collected from the selected regions. From the results, it shows that the sea waves peak periods are between 3 s and 5 s whereas the wave heights are between 0.5 m and 1 m respectively. The HOMER and analytical results show that the total rate of electrical power connected to the grid for Malaysia is 1408.81 MWh per year and 1408.89 MWh per year, respectively.
COVID-19 is the fifth pandemic to be documented since the 1918 flu pandemic. The virus spreads swiftly and evolves over time among humans because it is highly contagious. Since the virus is known to spread airborne, few of the most efficient ways to protect ourselves are by following social distance among individuals and to wear a face mask or shield at all times. These 2 conditions are not followed by some individuals even if the rules are set to be strict and it is impossible for the government to watch over everyone at all times. Companies and other sectors has to be allowed to operated even during the crisis due to economic factors. This is a risky situation for both the companies and the people. As a solution for this situation, a prototype is created to assist with social distance monitoring in public areas to reduce the risk of disease spread. The robot operates by using an Arduino MEGA, IR Sensors and Ultrasonic sensors. The robot comes with a robust and compact design to work in most places with the ability to follow a pre-determined path which gives it a tremendous market potential in all sorts of sectors that involves high number of employees or people.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
