“…However, temperature of 23 to 26°C is commonly used for human comfort in commercial buildings (MS 1525). The demand for electricity for cooling is increasing and leads to the utilization of renewable energy and sources of thermal storage [67]. In order to investigate the potential of GHEs for the Malaysian climate, analysis of local ambient temperature is essential.…”

The ground heat exchanger (GHE) is one of the energy sources that has been identified since the 1970s which is able to produce sustainable energy for cooling which is in passive side. GHEs are widely implemented around the world, especially in European countries and a few Asian countries. In Malaysia, application of GHE is still considered as a new passive cooling approach in building energy reduction. Therefore, this paper reviews several important ways of implementing GHE in order to supply passive cooling for any application. The review covers general implementation of the GHE for thermal comfort and agricultural greenhouse cooling. The ground temperature variation used in different researches is also reviewed in this paper as an important part of identifying potential GHE implementations. Design and performance aspects of the GHE are also reviewed. Finally, this paper summarizes the potential and benefit of GHE implementation in the Malaysian climate for cooling applications to reduce the energy used in buildings and greenhouse gas emission.

“…The temperature of 24 °C is commonly considered a human comfort level in both commercial and residential buildings. The demand for electricity for cooling is ever-increasing and leads to the utilization of renewable energy and sources of thermal storage such as the ground [5]. The ground has a high thermal inertia, where about 46% of the energy from the sun is absorbed by the earth, which causes temperature fluctuations at the ground surface attenuating deeper into the ground.…”

In equatorial countries like Malaysia, the cooling of buildings is almost entirely dependent on air-conditioning, with electricity as the main source of the energy required. As the country develops, with more buildings being built, and as the population grows, with more people demanding thermal comfort in the buildings they work and live in, the rate of electricity consumption for cooling purposes will continue to increase dramatically from year to year. This phenomenon requires the application of alternative energy options and thermal storage. Ground thermal storage is an example of thermal storage which can supply cooling and heating effects resulting in a significant reduction of electricity consumption. This paper discusses the potential of the implementation of ground thermal storage by using a ground heat exchanger (GHE) to supply passive cooling for any application. An analysis has been conducted based on an empirical equation from conduction heat transfer for depths of up to 30 m and thermal diffusivities from 0.04 to 0.1 m 2 /day. The main input parameters were obtained from a local weather station for three consecutive years. The result showed that a significant reduction occurs at a depth of 2.0 m and below, meaning that cooling can be supplied constantly throughout the year. The temperature amplitude is also attenuated relatively with depth, whereby amplitudes of less than 1 °C occur at a depth of more than 4 m with a thermal diffusivity of 0.04 m 2 /day. In addition, thermal diffusivity gives a significant increment in temperature amplitude and it is suggested to be maintained at a value of less than 0.06 m 2 /day. This result provides useful information to researchers and engineers in the field of underground installation of materials or systems such as gas pipelines, water supply and for underground cable transmittance.

Different hybrid configurations of wind, photovoltaic (PV), and diesel systems for a village in the north-eastern region of Saudi Arabia are presented. The configurations (i) diesel only, (ii) wind-diesel, (iii) PV-diesel, and (iv) wind-PVdiesel power generation systems are designed and compared to select the optimal alternative system by considering the minimum cost of energy and least environmental impact. For sizing and optimizing the hybrid power systems, local hourly average wind speed, hourly total solar radiation, and hourly load data have been used as input. Of the four configurations investigated, the diesel only system is found to be most cost effective with an energy cost of 0.037 US$/kWh with a fuel cost of 0.067 US$/l. Among the hybrid power systems, the PV-diesel hybrid system with 1,500 kW PV capacity, equal inverter capacity, and four diesel generators each of 1120 kW capacity are found to the most economical solution with a COE of 0.038 US$/kWh.
