Reduce Energy Consumption

In recent years, the construction industry has developed rapidly, and there are more and more urban construction projects. The corresponding design requirements for HVAC systems are also getting higher and higher. HVAC has been widely used in all kinds of buildings. While providing convenience for people, environmental pollution has gradually become a topic of concern for people. Therefore, when designing the HVAC system, HVAC not only meets the needs of customers, but also uses green energy saving technology to reduce energy consumption as far as possible. Reduce environmental pollution, so that the HVAC ventilation system of tall buildings can be in a stable and efficient operation state. Improve the operation effect of air conditioning, while reducing energy consumption.

Reduce Energy Consumption

In the face of a constant increase in demand for energy, one of the important sources will be its saving and efficient use. The search for the greatest opportunities in this area should focus on the areas where the highest energy consumption occurs. The dominant role here is played by the communal and living sector, to the extent that it is the sub-sector of buildings with a majority share of residential buildings. The article presents the expected energy effects of measures reducing energy consumption for heating residential buildings in the whole country. The author used statistical data of the Central Statistical Office available in the database of this institution. These data were identified and searched for as suitable for the purposes of this article and were used as a basis for calculations and analyses. The calculations show that only thanks to simple actions such as improvement of thermal insulation of envelope components it is possible to reduce energy consumption for heating of residential buildings by over 70% in relation to the situation in 2011. The potential energy effect will also translate into an economic and environmental effect. Qualitative measures such as improving the performance of the heating and ventilation system of a building and/or changing the energy carrier will also reduce energy consumption for this purpose, but they are not the subject of this study.

Reduction Of Energy Consumption

Abstract :  This study aims to determine the level of application of green computing at the Universitas Katolik Musi Charitas Palembang and recommend strategies in implementing green computing. Where green computing itself is the study and realization of the use of computing resources efficiently and environmentally friendly. The purpose of green computing is to increase the efficiency of use and reduce energy consumption and carbon footprint. Universitas Katolik Musi Charitas Palembang has long been using Information Technology (IT), one of which is a computer to support the ongoing process of the academic community. But the use of computers unwittingly provides a big role in environmental pollution and CO2 emissions. Based on the results of research that still needs to be socialized about understanding the importance of management and utilization in the use of IT equipment and policies to support the reduction of energy consumption and environmental pollution.

The vast increase of energy consumption, global warming and the harm they cause to the environment, emerge to be a major obstruction that distresses the world today. The current work views one of the methods that the world focused on as means of reducing the environmental harms and that is, through green building, or in more common words sustainable buildings. Those means, covers the exercising of a wide range of applications including merging of new and specific technologies in which through fulfilling its basis, the process of evaluation of the building takes place in terms of its harmony with the environment, reduction of energy consumption, and the reduction of the environmental problems caused by the building life cycle starting from defining of location, design of the building, operation, maintenance, repairing and up to the renewal of the building.  Despite the significance of green building, no profit nor implementations has yet been made in Libya. The latter is due to the lack of awareness by many Libyan social groups. From here, the idea behind this paper crystalized. It aims to spread and enhance the knowledge and techniques of green building. It also penetrates into the green building features and advantages that are considered to be a preliminary step to start its application in a wide range coinciding with the grand progress that the country has witnessed in the field of construction and housing. This paper concludes that it is possible to reduce energy consumption and the harm it causes to the environment after the implementation and merging of green building techniques and should be applied on a large scale covering the whole country.

Reduction Of Energy Consumption

Recently, since global warming has continued, reduction of greenhouse gas CO2 is required. CO2 emissions in the civil area sectors in Japan account for approximately 30%, which is about one-third of the whole of Japan. Therefore, reduction of energy consumption in houses, office and etc. is obviously required. In order to reduce energy consumption of buildings, high-efficiency of machinery, high-insulation, high-airtightness, and use of renewable energy are mentioned. Especially, use of geothermal energy which has almost constant temperature throughout the year has been drawing attention. However, in case of geothermal ventilation system, a fungi, dust, pollen and etc. derived from the outside air are taken directly into the pipe. It is concerned that they cause contamination inside the pipes and breeding of molds, which may lead to odors. The present study analyzed the contamination degree of the pipe surface in the geothermal ventilation system and proposed cleaning frequency in the pipe, cleaning method and so on.

Green building materials are a new category. Compared with the past building materials, ideal building materials have a series of characteristics such as reducing energy consumption, reducing emissions, saving resources, and being recyclable, which makes them become an important reference for sustainable development. This article focuses on foam glass, green walls, and ecological cement. During the research process, it was found that foam glass has better characteristics than ordinary glass, and less waste is generated during the production process, which reduces pollution; The green wall can not only reduce energy consumption, but also absorb harmful substances, and the plant exterior wall can also make people comfortable; Ecological cement can be made from waste materials, which greatly saves resources and realizes recycling. In short, green building materials are an important method to achieve sustainable development and will certainly play an important role in the future construction field.

Brundtland Report

In 1987, the Brundtland report defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The 30 percentage of the whole world greenhouse gas per year come from buildings. In many situation when architects design tall buildings, they often take into more consideration operational efficiency instead of some influence of environment. The consumption of energy ascend dramatically in developing counties, which leads to air pollutions and increase of greenhouse gas in these countries. In China, the number of tall buildings are increasing and these tall buildings take large proportion of energy consumption. The number of tall buildings was 400 until 2000 and the energy consumption of huge tall buildings is 6 to 8 times more than common buildings. Therefore, how to reduce energy consumption in tall buildings plays a vital role in sustainable development. The holistic sustainability includes three aspects which are economy, society and ecology. The purpose of this essay is critically assessing sustainable tall buildings in China and UK. Then limitation of holistic sustainability of building scale in China would be analyzed and how to enhance it.
