Vegetable crops are conducting under Farmers Participatory Research Trial in Temperate regions of Kashmir Valley. The trials are designed and managed by farmers, the researchers have only advice for selection of the resource conservation technology (treatments). Farmers have full control over the selection of treatments to be used on his/her field. The main objectives of this type of research is to be established and demonstrate the benefits of resource conservation technologies like raised bed, furrow irrigated planting system, zero tillage etc. over the conventional practices. In these type of trial farmers are briefed about new practices. The participating farmers are encouraged to experiment their own and are given the full control over the selection of subset of resource conservation technologies to be tested on their fields with a view to assess farmer innovation and acceptability.

Double Skin Facades

There was an indication that high rise buildings in Jakarta was not designed based on energy conservation principles. The most important aspects of the high-rise buildings is energy saving technology located in the building envelope design. Building envelope with a full glass design functions for widening view and enhancing natural lights, even though but it is also increasing energy consumption and thermal discomfort due to the intensity of solar radiation in hot humid climates. During the current decade, the development of double building envelope type (Double Skin Façade: DSF) seemed more just to improve the aesthetics and the use of natural light, while the wind and thermal performance aspects were still lack of serious consideration. Those aspects will be chosen as the subject matter in this research. The research was aimed to investigate and compare the value of heat transfer in the building envelope of high-rise office buildings. Samples were taken from five DSF buildings, with closed and open cavity. CFD software is used for simulation of the five different models of DSF. The research proves that the high-rise office buildings as the research object in Jakarta do not apply energy conservation principle. The utilization of wind in the DSF cavity can reduce temperature and relieve the burden of air conditioning systems that is energy save. An important finding of the research is the need for ventilation in the design of a double skin at high-rise office buildings in the humid tropics.

World Concept

Present energy use - largely dependent on fossil fuels - is incompatible with the sustainable world concept. In a sustainable world, energy sources are renewable and used in a way that damage to the environment is minimalized. This study investigates the possibility of a sustainable world using renewable energy sources. It appears that - when strict energy conservation is applied - such a sustainable world seems to be attainable. This requires, however, drastic changes in most parts of society.

This paper examines how a regulatory authority might ideally promote the formation of “conservation clubs” among households in order to initiate and empower voluntary household-level water and energy conservation efforts. We characterize a socially optimal conservation benchmark and derive the conditions necessary for a club to effectively attain this benchmark on behalf of the wider community. Both theoretical and numerical analyses are used to demonstrate ways in which households choose to become club members and are subsequently empowered to undertake conservation efforts. The avenues through which club membership might empower households include (1) information provision/education that is assumed to alter key parameters of the household’s welfare function, thereby inducing the household to build a stronger “conservation ethic,” and (2) bulk-pricing arrangements that reduce the prices of applicable conservation technologies. Our results highlight key relationships between the regulator and households, as well as between the club and the marketplace, that should be measured empirically before efforts are made to establish conservation clubs in practice.

High energy consumption is an important issue affecting the operation and development of wastewater treatment plants (WWTPs). This paper seeks energy-saving opportunities from three aspects: energy application, process optimization, and performance evaluation. Moreover, effective energy-saving can be achieved from the perspective of energy supply and recovery by using green energy technologies, including wastewater and sludge energy recovery technologies. System optimization and control is used to reduce unnecessary energy consumption in operation. Reasonable indexes and methods can help researchers evaluate the application value of energy-saving technology. Some demonstration WWTPs even can achieve energy self-sufficiency by using these energy conservation technologies. Besides, this paper introduces the challenges faced by the wastewater treatment industry and some emerging energy-saving technologies. The work can give engineers some suggestions about reducing energy consumption from comprehensive perspectives.
