Abstract:
The purpose of this study has been to conduct an energy diagnosis research of the third level. An energy diagnosis is a tool aimed to seek improvements related to measures of energy efficiency and saving, and environmental conservation as well. These improvements would prove to be relevant for any kind of building. The diagnosis was carried out in 36 university buildings (Renewable Energy Institute—REI) through survey and census; that in order (to identify and) to characterize current patterns of energy consumption and demand, as well as for generating specific strategies towards energy efficiency and saving, for instance the identification of systemic indicators and corrective proposals, and non-financial investment. The results promote the achievement of grand energy efficiency. The task on energy conservation entails the supporting participation of each person who either studies or works in the entity, whereas some other activities require economic stimulus for being implemented. Annual per capita energy consumption in the REI is 40 kWh/person: that is greater than the country’s average consumption rate. The main energy consumption corresponds to Building 3.1 (49% of total energy consumption). This is due to its large concentration of laboratories specialized in renewable energy research and innovation.Keywords:

Energy plays a key role in achieving the desired economic growth for the country. Worldwide industries use 40 percent energy for material and consumption protection to fulfil human needs which contributes almost 37 percent of global greenhouse gases emissions. One of the approach in order to reduce the emission of greenhouse gases to the environment is by conserving energy. This could be executed by implementing energy management especially in commercial and office buildings as daily electricity consumption is high in this type of building. Energy management can also increase the efficiency of energy in the building. Study has been conducted to investigate the performance on implementation of energy management system in office building. Energy management is one of the contemporary challenges, thus study adopts an exploratory approach by using a tool developed by UNIDO called EnMS or Energy Management System. Findings show that by implementing energy management can reduce electricity consumption up to 30%. However, serious initiatives by the organization are needed to promote the effectiveness of energy management.

This article deals with the energy performance of eight new and existing museum buildings located around Europe. Various energy efficiency and microclimate improvement measures have been adopted to reduce the energy consumption of the buildings and improve the comfort conditions. The investigation was implemented in two principal phases. During the first phase, energy simulation studies were performed in all buildings to evaluate the efficiency of the proposed measures and the various design possibilities. The energy consumption for heating, cooling, lighting and other electrical devices was calculated with and without the application of the proposed techniques and the corresponding energy conservation was estimated. Therefore, the proper measures from the energy point of view were adopted. During the second phase, measurements of the energy consumption were performed in the buildings after the finalization of the construction and the implementation of the proposed measures. The energy conservation was again calculated to evaluate the energy efficiency of the final construction. In addition to the energy aspect, the environmental impact of the final construction of the museums was investigated by calculating the reduction of the CO2 emissions due to the applied energy conservation techniques. Finally, the economic efficiency was examined by assessing the payback period of the adopted measures. The results of the present work show that the adaptation of energy conservation techniques in museums buildings can reduce significantly the energy consumption by respecting at the same time the requirements of the exhibition spaces and the comfort conditions of the visitors.

The purpose of this study is to identify the most relevant renewable energy technologies for buildings and to assess the effectiveness of their implementation in the long term for Kuwait. Methods of analogies and comparisons were used to determine the features of energy efficiency based on the technologies under study. The study proposes the methodological approach to assessing the effectiveness of the introduction of renewable energy technologies, determining the direction of increasing the energy efficiency of buildings and the investment efficiency of introducing these technologies. Renewable energy efficiency analysis for buildings in Kuwait confirms that solar energy systems have been the most widely available for widespread use of solar energy over the past three years. An increasing level of energy efficiency with a decrease in the notional cost of increasing energy savings is characteristic of solar collectors with booster reflectors. The proposed model for assessing the level of energy saving provides an opportunity for economic justification of introducing renewable energy technology in buildings.

Building energy performance analysis is a study to improve the energy efficiency of a building by determining the highest contributing factors towards energy consumption and proposing the energy conservation measures. This study is conducted to analyze the energy performance of a commercial building in the north Peninsular Malaysia. Low performance design of a building during the early stages could cause the inefficient usage of energy and decrease the thermal comfort. This research aims to analyze the highest energy consumption factor of a medium rise commercial building and identify the energy conservation measures that could contribute to energy saving without affecting the thermal comfort. Energy modeling using simulation tools is used to predict the energy consumption in the building and simulates some designs as strategies of energy saving. Thermal analysis also been done to obtain best practices of energy conservation measures. The study is able to come with designs that contribute towards significant of energy savings up to 52.82% and 36.44% in terms of Building Energy Index or Energy Usage Intensity and Annual Cooling Energy respectively.

Sustainable economic development necessitates a careful design of the energy infrastructure. The energy infrastructure is primarily composed of energy producers on the supply side, the energy consumers on the demand side and the network which connects them. The increasing energy demand, the spiraling cost of capacity addition and the global climate change scenario have put the energy infrastructure under enormous pressure. Reducing the demand by leveraging energy efficiency techniques is a major viable option towards redesigning the energy infrastructure. Energy efficiency analysis provides a basis for developing a detailed trajectory towards reduced energy consumption and sustainability. We present results of energy efficiency analysis at the machine level in the manufacturing sector which is a major user of the energy infrastructure.
