The air conditioned auditorium classroom was monitored for energy consumption by a monitoring platform. One year collected data from energy consumption and indoor climate monitoring systems and outdoor climate data in Phitsanulok province, Thailand, where its climate classified as the tropics, was employed to determine their relation by regression analysis. The analysis of climate data showed that the outdoor temperature above 26 oC was accounted for 70% of the year this emphasizes on cooling requirement. Furthermore, the hourly cooling energy consumption ranged from 8.1 to 10.3 kWh for indoor air temperature between 20 oC and 32 oC.  The higher outdoor temperature causes the greater cooling energy consumption. The correlation between outdoor temperature and cooling energy consumption with linear regression showed the correlation coefficient of 0.38 while the correlation between temperature difference and enthalpy difference of the outdoor and indoor found the correlation coefficient of 0.71. This pointed out that the outdoor tropical climate highly affected to the cooling energy demand.

Minimum Energy Consumption

Manufacturing industries have consumed 30% of the total world energy. The main energy source used in those manufacturing industries is the electricity generated from fossil fuels such as oil, gas, and coal as a result in causing the environmental and economic issues. This paper presents an experimental study in order to get the minimum energy consumption during turning of aluminum 6010 with the conventional machine tool under dry cutting condition by optimizing the cutting parameters to contribute to those issues. An analysis of variance (ANOVA) was employed to analyze the effects and contribution of depth of cut, feed, and cutting speed on the response variable, specific cutting energy. The result of this experiment showed that the feed was the most significant factor for minimizing energy consumption followed by the cutting speed and the depth of cut. The minimum energy consumption was obtained when the highest level of cutting parameters have been used.

AbstractSpecific energy consumption is an important indicator for a better understanding of the machinability of materials. The present study aims to estimate the specific energy consumption for abrasive metal cutting with ultra-thin discs at comparatively low and medium feed rates. Using an experimental technique, the cutting power was measured at four predefined feed rates for S235JR, intermetallic Fe-Al(40%), and C45K with different thermal treatments. The variation in the specific energy consumption with the material removal rate was analyzed through an empirical model, which enabled us to distinguish three phenomena of energy dissipation during material removal. The thermal treatment and mechanical properties of materials have a significant impact on the energy consumption pattern, its corresponding components, and cutting power. Ductile materials consume more specific cutting energy than brittle materials. The specific cutting energy is the minimum energy required to remove the material, and plowing energy is found to be the most significant phenomenon of energy dissipation.

The Tropics

Concrete remains the most utilised construction material for building envelopes, which regulate the indoor temperature to achieve human thermal comfort. Often, the energy consumption for building performance appraisal is related to the thermal behaviour of building materials as heating, ventilation, and air conditioning systems all variously contribute to human comfort. Following the development of concrete technology, many types of concrete have been invented to serve several purposes in the construction industry. To clearly understand the concrete type tailored for the specifics of a construction project, the local climate, concrete mechanical properties, and concrete thermal behaviours should be primarily identified to achieve energy efficiency, which also suits the sustainability of global materials. This paper, therefore, reviews the modified concrete thermal behaviours in the tropical climate for more systematic city planning in order to achieve better energy efficiency. Urban heat islands in the tropics and contributing factors, as well as heat transfer mechanisms, are first highlighted. The requirements of concrete thermal behaviour for building envelopes are then discussed through specific heat capacity, thermal conductivity, thermal diffusivity, time lag, and decrement factor in the context of applications and energy consumption in the tropical regions. With a case study, it is found that concrete thermal behaviours directly affect the energy consumption attributed mainly to the use of cooling systems in the tropics. The study can be a reference to mitigating the urban heat island phenomenon in the planning of urban development.
