Save Energy

PurposeEnergy-saving behavior of individuals is essential to minimize energy use and reduce the emission of toxic gases. This study's actual focus is to find out the determinants of the energy-saving behavior of individuals in the workplace.Design/methodology/approachAs a theoretical research model, the extended theory of planned behavior (TPB) has been used to analyze the determinants of energy-saving intentions. A survey method is used to collect 289 valid data, and structural equation modeling (SEM) is used to analyze the data.FindingsThe final result shows that the variables attitude at home, subjective norm (SN) and descriptive norms positively impact intention to save energy at the workplace. In contrast, the construct attitude and perceived behavior control is insignificant in this research. On the other hand, the personal moral norm (PMN) is a powerful predictor of individual energy-saving intentions at the workplace.Originality/valueThis research provides insights that will help the organizations understand the behavior of individuals at the workplace for energy-saving intentions to formulate such policies that will enhance individuals' practice for energy savings.

The most important part of energy use in hospital buildings is to identify its usage patterns and maintain power supply even in blackout situations, rather than to save energy. This paper presents the power energy usage patterns of general hospitals as basic data for the establishment of countermeasures in blackout situations.

A Performance

In recent years, the need for comfortable visual environments in indoor spaces has increased energy use in buildings. There have been diverse studies on using a light shelf to solve this problem. It is an effective system that allows external natural light deep into indoor spaces through reflection. However, prior studies have used light shelves with a fixed reflectivity, and there are few studies on improving the visual environment through light shelf control. Therefore, this study proposes a movable light shelf with a rolling reflector that can change the reflectivity. To achieve these objectives, we conducted a performance evaluation of the system’s ability to save energy and improve the visual environment. This study built a real scale testbed and conducted a performance evaluation by deriving values for lighting energy consumption, uniformity, and luminance contrast depending on the light shelf variables. We conclude that (1) the light shelf system achieved an energy savings of 13.6% and 5.7%, respectively, compared to a fixed type light shelf, whose reflectivity cannot be changed, and a traditional movable light shelf; (2) in terms of improving the visual environment, results suggest that the visual environment could be improved using a light shelf by deriving light shelf variables that disturb indoor uniformity; and (3) the results verified glare generation conditions by deriving luminance contrast caused by the variables of light shelf angle and its reflectivity.

The Cost

Photoelectric switching has the potential to save energy by turning off lighting when daylight illuminances are adequate. However one problem with this control type is frequent switching, annoying occupants. This paper examines three types of control algorithm which can reduce the number of switching operations. Under differential switching, the lighting is switched on if the illuminance falls below a critical value Eon, but not switched off again until the illuminance reaches a substantially higher value Eoff. Another option is the use of a time delay. The final control mode is solar reset where the lighting can only be switched off at certain set times of day. Operation of the various controls was simulated using model room illuminance data recorded every minute. The analysis reveals that solar reset gives the fewest switching operations but at the cost of increased energy consumption. A time delay, where the daylight illuminance has to exceed a target value for a set time before switching off can occur, gives the fewest switch offs for a given lighting energy use. However differential switching ensures that switching off occurs at a favourable adaptation level. The paper outlines ways to predict lighting energy use under the different control strategies.

Modern House

Space cooling and heating in residential sector is significant contributor to energy consumption in Australia. Therefore, it is important to reduce the cooling and heating requirements. The selection of a good walling system helps to save energy by homes. This research compared the thermal efficiency of a modern house (constructed using brick veneer walls with concrete floor slab) with an old house (constructed using fibro cement walls raised timber floor) using the AccuRate simulation tool. A standard house with two living rooms, one kitchen, one laundry and four bedrooms are simulated in a Sydney Suburb in Australia. It was found that modern house showed lower inside temperature variation than the old house all year around. The results also showed that the modern house has a lower energy consumption for space heating and cooling than the old house. The annual energy use for space heating and cooling in both the modern house and old house were 5197 kWh and 15,712 kWh respectively. Moreover, the annual energy costs were found to be $1,403 and $4,242 respectively for modern and old houses. The modern brick veneer house saved about 33 % of energy compared to old old house. When the net present value of the energy cost for f both houses over 50 years is computed, the energy cost of modern house was found to be $25,629 while it of old house is was $77,488 for the old house.

Steam Drying

In order to reduce the energy use it is useful to divide the different processes in the factory into energy “users” and energy “transformers”. The juice evaporator train is a “transformer”. When designed correctly all ingoing energy will leave the evaporator to be used elsewhere. Drum drying of pulp and the sugar house are “users”, as most energy supplied cannot be recovered. To save energy requires attention to the “users”, and the “transformers” shall be adapted to fit into the system, so they are only transformers. Examples of this are given. In doing so, it is possible to come down to approximately 140–150kWh supplied energy as fuel. This includes making sugar into white sugar, molasses with a purity of around 60%, and drying all the beet pulp. Energy saving offers reduced CO2 emission. Half of all the VOC (volatile organic compounds) leaving a sugar factory comes from the drum drying of pulp. Steam drying, however, produces no VOC and no dust emission to the atmosphere at all.

This article is a joint development of ways to improve the efficiency of business processes of energy use, taking into account innovative development and modernization of the economy in modern conditions. The energy industry is regarded as a leader in introducing innovations among other industries. The solutions are proposed to reduce energy consumption using advanced technologies. The features of energy supply to consumers in difficult conditions of economic, technical and climatic nature are identified, provided that large systems with a high level of complexity of system interconnection are integrated. The necessity of restructuring the entire global electric power network of the Russian Federation on the principles of multifunctional automation is substantiated. The main focus is on the use of “smart home” technology. This technology is considered as one of the most promising areas for the economical use of energy. The use of Smart Grid and Smart Home technologies significantly improves the efficiency of business processes using different types of energy, which allows planning plan energy consumption more accurately. The studies have shown that the use of innovative technologies can save up to a third of the energy consumed, but the population has no significant motivation to plan and save energy, which negatively affects the mass introduction of these technologies. However, there is a positive trend in the use of Smart Grid and Smart Home technologies in optimizing the management of business processes by business structures, for example, in optimizing security tools, managing household engineering systems, etc.
