Abstract In the hotel business, the use of energy is very important, especially in the use of electricity, the portion of usage and allocation of funds for its provision is the largest. It can be seen that equipment such as lights, elevators, refrigerators, laundry, heaters, pumps, to the air conditioning system are some of the dominant tools in operations in the hospitality world. The results of the initial energy audit and detailed audit at the Grand Clarion Hotel Makassar showed that the Energy Consumption Intensity (IKE) is still far from the standard, which is 300 kWh / m2 a year. The building uses the largest amount of electricity in the Grand Clarion Hotel Makassar in Building A, which is in the Guest Room area of the air conditioning unit. The results of the initial energy audit of Energy Consumption Intensity (IKE) electricity were 336.84 kWh / m2 year. Whereas based on the results of a detailed energy audit the electricity consumption intensity (IKE) of electricity is 395.51 kWh / m2 a year. Energy Saving Opportunities (PHE) in this energy audit is to evaluate the AC power in each room and recommend the replacement of lamp types. From the results of the IKE calculation after the application of PHE, it is found that the value is still quite high so that efforts to save must still be done.

The Impact

The continuing importance of energy conservation in the building sector has drawn major attention to energy audits of existing buildings in different climates. In this paper, the energy conservation potential of a residential building located in Iran’s cold climate was investigated through an analysis of its actual energy consumption and through computer simulation. The building base-load was determined using a linear regression method based on existing energy bills, and was used to validate the computer simulation of its energy usage. The impact of typical energy saving solutions was evaluated for three cost refurbishment scenarios: low, medium and high. The results show that the existing construction and envelope materials fail to meet the national standards of Iran, but insulating the envelope was found to be a more cost-effective measure than modifying the windows. The results also demonstrate that although the use of energy-saving solutions has a significant impact on energy consumption, even the most economic solutions investigated will have a payback period longer than one decade. Thus, with current energy prices the reviewed energy conservation strategies are not economically justified in Iran from the consumer perspective, as investment in the methods considered typical in other parts of the world will not show a return for at least a half-century.

An energy saving residential building in Zhangjiakou was took as research object, which was designed and constructed according to the criterion of 65% energy saving of the third stage, utilizing simulation software Dest, which was developed by Qinghua University, energy consumption simulation and economic analysis were done to the building. The results show that compared with the former residence which was built according to the non-energy saving design, the implementation of new design standard for building energy saving can not only achieve better energy saving effect, but also its payback period is short, so the new design standard for building energy saving is worth spreading.

AbstractThis paper presents the results of a study that explored the effectiveness of three intervention strategies in facilitating energy saving behaviour among resident undergraduate university students. In contrast to a dominant practice of motivating with rewards or competition this study sought to appeal to students' intrinsic motivations. An experimental design was used with two intervention groups and a control group. The interventions were the provision of real-time feedback provided by an inhouse energy consumption display unit (ecoMeter) and a targeted social marketing approach. They were evaluated using energy consumption data and self-report data from the participants via an on-line survey and focus groups. Across the three research phases the rate of reduced electricity consumption for the interventions ranged from an average of 17% to 28% less than the control group. The findings provide evidence that facilitation of intrinsically motivated behaviours can result in reduced energy use and greenhouse gas emissions.

A plan for the sequential implementation of the software product into operation at the enterprise is presented. The dynamics of electricity consumption at the enterprise, the structure of energy consumption are illustrated. It is noted that the most significant contribution to the amount of energy consumption is made by the technological processes of water intake and supply. It has been substantiated that the most energy-consuming process for the enterprise (Water Supply Branch of the State Unitary Enterprise St. Petersburg Vodokanal) is replacement or maintenance of pumping equipment. The components of energy conservation of the enterprise under study are the partial regulation and automation of processes.

An on-site test on envelope of a typical steel residential building in cold region is performed. The testing results provide evaluation bases for the energy-saving effects of the steel residential building. In order to evaluate the main factors that influence energy dissipation of the building and estimate the main energy dissipation positions, the heat transfer coefficient K of envelope and its actual energy consumption are calculated based on the testing data. The results indicate that the building envelope has good heat storage property and it could keep indoor thermal stability; the steel frames and windows have heat bridge effects. Through calculations of the energy consumption of envelope, it is showed that the tested building only meet the requirement of energy saving by 50%, instead of 65%; the external walls and windows are main energy dissipation parts. Finally the thermal design recommendations about steel residential buildings are proposed.
