Abstract: In today's globalized world, rapid depletion of natural resources, increased air and water pollution, deforestation and climate change are major environmental problems for industrial activities. Many industrial activities contribute to environmental pollution by causing these problems. Therefore, it is of great importance to develop environmentally friendly production methods, reduce resource consumption and minimize environmental impacts. The yarn dyeing industry is a sector where natural resources are used intensively and environmental pollution problems are seen. Innovations in this sector aim to make production methods more sustainable. In particular, process reduction is an important step in reducing resource consumption and minimizing environmental impacts. This provides an important opportunity to conserve natural resources and produce environmentally friendly products. Therefore, with the increasing demand for ecological products, it is aimed to develop an environmentally friendly, sustainable and environmentally sensitive process in yarn dyeing. With the new process developed within the scope of the project, a dyeing study was carried out using the natural color of raw cotton yarn. The first bath pre-treatment we apply to raw cotton yarn allows us to make homogeneous dyeing. Thus, it was possible to reduce the need for some chemicals and natural resources that are harmful to nature. The new process developed within the scope of the project is gaining importance in the textile industry due to limited natural resources and increasing environmental problems. The aim of the project is to reduce the use of water, energy and chemicals by eliminating the bleaching step used in traditional yarn dyeing processes and to create an environmentally friendly product platform. In this way, with the increasing demand for ecological and sustainable products, customer expectations can be met and the company's environmental impact can be reduced. In addition, this new process, which saves energy and water, offers the opportunity to gain a competitive advantage by providing cost savings in the textile industry. Therefore, the new process developed sets an example for other businesses in the sector, benefiting both the environment and the operation of the company.

The survey content includes family background, house layout design, construction and cost, details and energy consumption simulation, temperature test etc. The paper summarizes the reasons for the popularity of the ICF system and the issues that need attention in future promotions. Construction optimization is also proposed for thermal bridge at the window opening, so that this new system can exert a more comprehensive energy-saving performance.

Abstract: Combining with the energy consumption of air-conditioning system and the characteristics of the cooling and heating load in the hotel, the authors analyse the energy-saving property and necessity of adopting condensing heat recovery from water chillers. Taking the air-conditioning system of a star-hotel as an example, the optimization design for condensing heat recovery system from chillers on raising the temperature difference between supply and return water, the hot-water tanks in series and the water temperature stratification effectively realizes cascade and sequential utilization of hot-water, which keeps the water temperature stable and becomes more energy-saving.

Abstract: Insulating glass is the main function material of the building curtain wall and building windows and doors, which plays a significant role in the energy-saving function more than 50% of the whole building. In recent years, the thermal insulating property and sound insulating property of insulating glass improves greatly with the combination of vacuum glazing. With the combination of PV (photovoltaic) glass, insulating glass has structural-function integration characteristics. Vacuum glazing and BIPV are two important types of insulating glass which are developing rapidly. In this paper, research developments and test experience of vacuum glazing and BIPV were summarized. Through analyzing the energy-saving test data of vacuum glazing and BIPV, the energy-saving influencing factors were given.

Abstract: The traditional electric heating device mainly used resistance wire as the electric vehicle components. A novel semiconductor nanoelectrothermal film as a heating material was to study its feasibility. By analyzing the heating mechanism of electrothermal film and comparing the existing heating device, an energy-saving heater was designed based on semiconductor nanoelectrothermal film. In STC89C52 micro-controller core, a practical and stable temperature control system was devised by a variety of control methods - shock control, relay control, pressure control, and so on. The energy consumption experiments were done between new electric heating device and conventional heater, and the results showed that new electric heating device had more energy efficient. On the basis of this study, a series of electric heating products could be developed with low power and environmental protection, and it was a useful exploration for technology upgrades for the electric heating industry.

Abstract: This paper addresses the issue of associating a concept of industrial smart grid technology for a reactive power control of reversible electric drives. The research focus was concerned with the theoretical analysis of active, reactive and apparent power by the main reversible electric drive of plate mill rolling stand. Typical features of power electric equipment of modern reversible electric drives allow us to develop the reactive power control. The reactive power control can be created out by using of back to back converters which connect the reversible electric drive with the supply mains. Experiments in the plate mill were carried at the difficult-to-form steel grade in the range of roughing and finish rolling. It was established that the reactive power generation can be used in the range of the roughing. The huge prospects of the reversible electric drives integration based on back to back converters in Industrial Smart Grid have been determined due to the fact that to control of reactive and apparent power flows.

Abstract: March to May at noon control area (exposed roof) temperature of 37.56°C, test below (green roofs) surface only 24.69°C, 24.79°C room temperature on the second floor, planting mean temperature of 27.6°C, effectively prevent the roof surface temperature rise, and thus reduce the interior roof of the second temperature 12.77°C . Building extensive green roofs to cooling, mainly to reduce the building room temperature of 3.76°C;reducing air conditioning electricity consumption , accomplish cooling and energy-saving benefits.March to May at noon (12:00-13:00), ANOVA analysis of cooling efficiency, the temperature difference between the building control area as the dependent variable, compare independent variables, and found that different monitoring areas of solar radiation cooling effect,2 floor indoor cooling temperature 13.9083°C, efficiency the most significant.Roofs of buildings spring will be applied as extensive green roof in spring, creating building roof thermal comfort (24.88°C) and Auliciems (1981) estimate room comfort temperature (24.55°C) are similar, significant benefits to achieve room thermal comfort.Buildings is applied for green roofs in the spring can reduce home power consumption (reducing air conditioning systems use frequency), to energy-saving (58.17%) of the economic benefits.

Abstract: At present, research on energy-saving and emissions reduction is still mainly theoretical construction and not much quantitative research on evaluation, particularly study of the empirical analysis on the provinces and the national is rarely. In order to arrange energy-saving and emissions-reduction better, achieve the strategic target for energy-saving and emission-reduction, improve production environments, make comprehensive use of resources and develop circular economy, the establishment of a comprehensive and perfect evaluation system of province-wide energy-saving and emission-reduction is of great significance both to the region and the country. This thesis attempts to build up a set of 19 indicators specific indicators system, can basically achieve targets for the quantitative evaluation of province-wide energy-saving and emission-reduction.
