The effect of building envelope on the thermal comfort and energy saving for high-rise buildings in hot–humid climate

Abstract: This paper is about the research into the effect of building envelopes on energy consumption and thermal performance of high-rise buildings in the Malaysian Tropical climate. A suitable indoor thermal condition in buildings is important because of the building occupants comfort. In addition, it is indicating building energy consumption, staff productivity, less absenteeism, health and well-being effects. Energy consumption can be significantly reduced by adopting energy efficiency strategies in such buildings. Due to environmental concerns and expensive energy costs in recent years, energy efficiency in buildings has garnered renewed interests. A research recently conducted in Malaysia specifies that residential buildings do about 19% of the overall energy consumed in Malaysian sectors. One of the most potential strategies applied on building envelope in hot–humid tropical regions is the passive design method and is done to the building envelope in hot–humid tropical regions. This paper reviews the results of the other studies that establish to the selecting of proper parameters of building envelope to the high-rise residential. The building design criteria has been scrutinized through a set of defined parameters such as climatic conditions, form, width, length and height, external walls, roofs, glazing area, natural ventilation and occupants thermal comfort, as well as external shading devices on energy consumption of high-rise buildings in Malaysia. The thermal comfort zone was investigated by researchers for Malaysian residential buildings, discovering that the comfort ranged between 25 °C and 31 °C. Recommendations are given based on the significant findings as resources to help designers in laying out the design plan for high-rise buildings in hot and humid climate.

Reviews on Various Inertial Measurement Unit (IMU) Sensor Applications

Abstract: Inertial Measurement Unit (IMU) sensors are used widely in many different movable applications. Across many years, the improvements and applications of IMU have increased through various areas such as manufacturing, navigation, and robotics. This paper presents a literature review of several current IMU categories and applications. A few considerations on choosing an IMU for different applications are summarized and current methods being used to improve the accuracy of the output from IMU are also presented to avoid the errors that latest IMU is facing. Improvement methods include the control algorithms and type of filters for the sensor. Pros and cons of the types and algorithms used are also discussed in relation to different applications. 
