    This paper focuses on the concept of zero energy consumption building (ZECB). This paper has implemented the Thai mediation building, which designed and built using ZECB concept. The Thai mediation building requires zero energy from the grid because the main source of energy comes from the solar energy via photovoltaic system. Energy budget is used to calculate the relationship among energy generation, energy load, and energy storage, which is useful to construct any zero energy building.

    Energy budget parameters consisting of feed intake, food digestibility, absorption efficiency, oxygen consumption, and ammonia excretion were investigated in 3 size classes of Thai abalone Haliotis asinina (2.22 ± 0.13, 3.27 ± 0.02, and 4.16 ± 0.05 cm in shell length). These abalone were fed with artificial diets (approximately 28% crude protein) and held at 28.0 ± 1.0°C and 31.0 ± 1.0 psu salinity. The daily feeding intake of H. asinina decreased with size class, ranging from 0.75% to 0.48% of their dry weight tissue. However, high absorption efficiencies were observed in all 3 size classes, with an average of 81.04%. Further calculations of the obtained energy from the artificial diet for the 3 size classes were 273.6, 666.9, and 1,744.2 J/day, for the 2-, 3-, and 4-cm size classes, respectively. More than 30% of the obtained energy was used for metabolism (ranging from 33.242.5%), whereas the energy used for ammonia excretion was low (ranging from 0.81.8%). Scope for growth of the abalone varied between size classes (ranging from 37.445.8% of the obtained energy). Results from this study suggest the Thai abalone H. asinina fed with this artificial diet and reared in a semiclosed recirculating water system were in optimal culture conditions, because the feed intake resulted in high-energy absorption that allowed a positive energy balance.
