Saving energy is one of the most actual topics for today. Modern buildings and facilities have huge reserves to increase their thermal eiciency. Energy consumption of buildings, which was not signiicant for the past, has become the dominant measure of the quality of the project. Over time, modify and extend the object of study: energy eiciency in buildings and structures. If at the beginning of the construction of energy eicient buildings, until the early 1990s, the main interest is the study of measures for energy saving, then in the mid-1990s, priority is given to energy- eicient solutions that simultaneously contribute to the quality of the microclimate. In the construction of a large number of buildings, neighborhoods and even architectural zones which have been designed and constructed based on diferent concepts of energy eicient and environmentally friendly technologies. hese concepts are deined by their own names. Most famous were the following ones: energy- eicient buildings and structures; buildings and structures with low power consumption; buildings and structures with ultra -low power; buildings and structures with zero energy use; passive buildings and structures; bioclimatic architecture; healthy buildings and structures; "Smart" homes and buildings; intelligent buildings and structures; building and construction of high-tech; environmentally neutral buildings. In our country, buildings account for almost half of the country’s total energy consumption, or 17 million tons of oil equivalents, annually. Many buildings are now physically worn out and planned for reconstruction or rehabilitation. Increasing population places growing demand in education and healthcare services, which requires further renovation of the existing ones and construction of new public buildings. Energy eicient construction is a safe bet and creates independency from the luctuations in energy costs. REHAU system solutions cover all three pillars of energy eiciency: Creating energy eiciently, using energy eiciently, and reducing energy losses. With innovative materials and highly developed system technologies, we ofer our customers highly eicient options for positive energy rating and economical solutions for exceeding the EnEV [1]. Currently, the construction of buildings continued to follow outdated rules and practices in the construction industry, where energy eiciency considerations have not yet taken into account in the process of design and construction, which leads to excessive consumption of energy and makes a great contribution to greenhouse gas emissions in *Corresponding author: Bonu Azizova, Tashkent Architecture and Construction Institute, Uzbekistan, E-mail: bonu.azizova@gmail.com Received April 21, 2015; Accepted June 10, 2015; Published June 30, 2015 Citation: Azizova B (2015) Energy Eficiency is the Main Objectives in Construction and Reconstruction.

Energy Efficiency is the Main Objectives in Construction and Reconstruction Bonu Azizova* Tashkent Architecture and Construction Institute, Uzbekistan the country. In order to solve these demographic and social problems, the government has taken a number of large-scale programs for reconstruction and construction of public buildings, including schools, colleges, kindergartens, hospitals and sports facilities [2]. hese programs have targets at improving the energy eiciency of buildings, which include new opportunities for energy-eicient building through improved design and technology. One of these reconstruction objects in our country is the building of the Institute of Immunology, National Center of Legal Medicine in Tashkent. he foregoing examples of the construction and reconstruction of the buildings, that increased energy eiciency, are the part of sustainable development in architecture. Sustainable buildings and structures includes the study of the possibility of the use of clean renewable energy, the optimal use of the requested energy, water conservation, use of building materials reuse, improve the quality of the human environment [3]. Nonetheless, the study of several aspects of the problem is insuicient: it is necessary to study the complex development and the environment, and their environmental and energy potential, through a complex of measures for energy eiciency program, gradually introduced new technologies, constantly approaching the main goal is sustainable development as architecture as like the whole State. his is the main purpose of the theory and construction practices today (Figure1). he design of the building of the Institute of Immunology at the National Centre for Legal Medicine in Tashkent was completed by "UzTibloyiha". he principal recipient/beneiciary of the building the Ministry of Healthcare of the Republic of Uzbekistan, General Contractor is "Ulkan Qurilish" LLC (Figures 2-4). Technical characteristics of the building • Heated area according to the design – 4,705 m 2 • Annual energy consumption for heating and ventilation – 647,878 kWh/year
