The article analyses critera applying to the choice of energy efficient high quality light sources and luminaires, which are used in Russian domestic and international practice. It is found that national standards GOST P 54993–2012 and GOST P 54992– 2012 contain outdated criteria for determining indices and classes of energy efficiency of light sources and luminaires. They are taken from the 1998 EU Directive #98/11/EU “Electric lamps”, in which LED light sources and discharge lamps of high intensity were not included. A new Regulation of the European Union #874/2012/EU on energy labelling of electric lamps and luminaires, in which these light sources are taken into consideration, contains a new technique of determining classes of energy efficiency and new, higher classes are added. The article has carried out a comparison of calculations of the energy efficiency classes in accordance with GOST P 54993 and with Regulation #874/2012/EU, and it is found out that a calculation using GOST P 54993 gives underrated energy efficiency classes. This can lead to interdiction of export for certain light sources and luminaires, can discredit Russian domestic manufacturer light sources and does not correspond to the rules of the World Trade Organization (WTO).

The Impact

<p class="Abstract"><em>The surface temperature of the building material may release a heat load in the micro-environment. The largest building envelope receives the heat load of solar radiation is the roof. The strategic roof position at the top of the building has the opportunity to radiate heat received into the environment. Heat emissions lead to rising temperatures, so it is necessary to lower the temperature in micro-environment. When the heat of the building is not lowered will lead to an increase in the urban heat island (UHI). The objective of the study was to find the relationship between the thermal performance of the roof of the building and the energy efficiency in the high-rise building, in order to establish efficient thermal comfort. The research method uses experimental way in real model which is in Surakarta City, as humid tropical climate area. The result of the study is a comparison of the heat performance of three roofing materials which would later recommend the criteria of energy efficient roof for high buildings.</em><em></em></p>

Technical Measures

Mass concrete is widely being used in the construction field, especially for the foundation of super high-rise building. In the initial stage of pouring completion of mass concrete, lots of heat generated from the cement hydration will lead to a high temperature inside of concrete. When the temperature difference between the inner and outer of concrete exceeds the limited value, thermal stress will be greater than the tensile strength of concrete, which may cause hazardous penetrating cracks of the structure. To ensure the safety and durability of concrete structure, necessary measures should be taken to control the temperature rise and construction quality of concrete. Taking a super high-rise building project as an example, this paper introduces several effective solutions to resolve above problems. The technical measures such as enhancing the concrete quality, controlling temperature rise, strengthening temperature monitoring would be detailed illustrated. Meanwhile, valuable suggestions achieved from this practical project are proposed in order to guide the structural design and on-site construction of similar projects.

The challenge in the design of bioclimatic high-rise buildings is to return to a design that is compatible with the environment, climate. The purpose of the article is to analyze the means of color formation in living and inanimate nature, which can be used in color solutions for the facades of bioclimatic high-rise buildings to ensure their durability, regulate energy efficient and environmental parameters (thermoregulation, illumination, humidity). The need to analyze and research the bioclimatic trend in the design of modern high-rise buildings is based on the emergence of a significant number of implemented innovative design solutions. Such projects differ from each other in architectural styles, directions and means of implementing the bioclimatic approach, placement and interaction with the environment. The application of various natural mechanisms of color formation in nature is analyzed from the point of view of ensuring functional use in facade solutions of modern high-rise buildings. The main advantages of the pigment and structural mechanism of color formation to ensure thermal insulation of the building, durability of facade finishing while maintaining the quality of color solutions are determined. The results of the study made it possible to establish that today the use of the bioclimatic approach to the use of color in the facades of high-rise buildings determines new trends in the creation of eco-facades, based on the use of natural analogues and associated with the introduction of the latest design and technological solutions.

With the consolidation of the Internet of Things (IoT), the unmanned aerial vehicle- (UAV-) based IoT has attracted much attention in recent years. In the IoT, cognitive UAV can not only overcome the problem of spectrum scarcity but also improve the communication quality of the edge nodes. However, due to the generation of massive and redundant IoT data, it is difficult to realize the mutual understanding between UAV and ground nodes. At the same time, the performance of the UAV is severely limited by its battery capacity. In order to form an autonomous and energy-efficient IoT system, we investigate semantically driven cognitive UAV networks to maximize the energy efficiency (EE). The semantic device model for cognitive UAV-assisted IoT communication is constructed. And the sensing time, the flight speed of UAV, and the coverage range of UAV communication are jointly optimized to maximize the EE. Then, an efficient alternative algorithm is proposed to solve the optimization problem. Finally, we provide computer simulations to validate the proposed algorithm. The performance of the joint optimization scheme based on the proposed algorithm is compared to some benchmark schemes. And the simulation results show that the proposed scheme can obtain the optimal system parameters and can significantly improve the EE.

Placement Algorithm

Energy efficient virtual machines (VM) management and distribution on cloud platforms is an important research subject. Mapping VMs into PMs (Physical Machines) requires knowing the capacity of each PM and the resource requirements of the VMs. It should also take into accounts of VM operation overheads, the reliability of PMs, Quality of Service (QoS) in addition to energy efficiency. In this article, the authors propose an energy efficient statistical live VM placement scheme in a heterogeneous server cluster. Their scheme supports VM requests scheduling and live migration to minimize the number of active servers in order to save the overall energy in a virtualized server cluster. Specifically, the proposed VM placement scheme incorporates all VM operation overheads in the dynamic migration process. In addition, it considers other important factors in relation to energy consumption and is ready to be extended with more considerations on user demands. The authors conducted extensive evaluations based on HPC jobs in a simulated environment. The results prove the effectiveness of the proposed scheme.
