The eco-friendly elements are important for new construction and renovation and redevelopment of the buildings. The green buildings are related with minimizing environmental pollution and how to live with nature throughout the entire process of demolishing and building. The purpose of this paper is to study on eco-friendly business buildings in the trend of mandatory green building certification system. The analysis of this paper is comparative studies on practices at eleven domestic eco-friendly business buildings through site survey on design framework of green buildings. The design framework of eleven this buildings is six kinds of skills on technical, renewable, ecological, cultural, healthy, social. The eleven this buildings in the new & renewable energy and IT technology of technical sector are satisfied with the framework. But, domestic most advanced eco-friendly business buildings are placed difference between almost the two times on the lower buildings at comparative evaluation. The three of this buildings are gratified rainwater harvesting and waste recycling systems for renewable and recycle. The buildings have an excellent aspects of technology and ecology. The benefits of this buildings are related with future compulsory zero energy house to take technical advantage of renewable energy. However, the buildings reflecting the regional culture types is insufficient. The buildings should be supplemented as follows. This buildings are need to have the social enhancement programs and design for convenient space of community residents, through health and comfort of on workplace. Moreover, this buildings have features of coexisting with human beings and nature friendly with the aim of realizing the sustainable development. The social enhancement programs through regional cultural aspects with ecology are related with individual and community livings in harmony, non-hierarchical communal lifes. The development of the cultural aspects provide for consensus about the local community and creating sustainable communities. Thus, The buildings are to have energy saving, pleasant and healthy living environment and interactive individual and community livings in harmony.

Current supervision systems have been changed by the demands of social, physical and institutional environment, and have a role of preventing safety accident and in improving the construct ability through the analysis of issues in quality, time, construction, safety, and environmental management. The public sector "Construction Technology Management Act", a general and private sector "Building Act" and "Certified Architects Act", the residential building "Housing Act" are dealt with supervision systems, respectively, but private small building construction is excluded from the discussion of the main targets because of their relatively small scale and the lack of social interests, Thus, this study focused on the small buildings for improving the non-resident supervision systems. Survey results revealed that the non-resident supervisor needs to be selected not by clients but by officers in order to obtain its publicity. Based on the proper selection and execution of the supervision system suggested in this study, the potential effects can be summarized as 1) recovering of publicity, 2) correcting abnormal practice, and 3) realizing design intention for increasing the public value of buildings. In addition, findings in this study will be effective to amend current non-resident supervision systems for improving the quality of buildings and communities as well as for adopting the environmental-friendly energy-efficient smart building technologies.

Lately construction industry tends to prefer remodeling of existing buildings rather than new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. And also, remodeling of building costs less and creates less wastes compared to reconstruction and so it is more profitable in financial and environmental view. However remodeling is process of creating new environment with existing building. Therefor remodeling must follow the procedure realizing problem and fix the problem based on through investigation on existing building and users requirement must be faithfully reflected. Specially in case of apartment houses, since vagueness on ownership and management authority on common parts exists. Hereupon, in this study we are to present the procedure of analyzing apartment house remodeling method through user requirement by approaching to several considerable factors in user request side.

Employers are realizing that workplaces have an immense impact on productivity. And, because people typically represent about 90% of a company's costs, even a slight improvement in productivity hits the bottom-line in a very big way. The focus is shifting away from saving money by reducing space needs or cutting energy requirements, and moving toward making the workplace friendlier and healthier. What is a healthy workplace, exactly? The answer should be clear by now. Mountains of research have expounded on this very topic, and then news outlets cover the latest discoveres ad infinitum. The problem is, research is rather dense, while the news isn't comprehensive. Office managers trying to improve workplace wellness want neither a 55-page report nor a half dozen articles to convince their landlord that their space can do better. Recognizing this gap, Harvard researchers have released a concise-yet-complete list of healthy building features. Here, we're sharing these nine features with a few insights of our own on the value of being healthy and productive. Find out: ${\bullet}$ What makes a healthy building and why is it so important ${\bullet}$ How to improve the health of your own office ${\bullet}$ What happens for your people and your bottom line when you make health a priority.

This study investigates and analyzes natural traits in Gaudi's architectural designs on the assumption that the naturalism in his architectural designs has been built heavily on regional cultural background. In particular, focusing on four buildings Gaudi designed in his late years, this study distinguishes between natural traits found in ornaments and details, and natural traits as organic expression of form. This study shows, first, with regard to natural traits in ornaments and details, organic motives were applied to patterns, plastic objects, and parts of the building. Second, natural traits in organic expression of form were reflected by typifying $Catalu\tilde{n}a$ regional nature, using curved lines of organic shapes and realizing lively natural creatures. It is remarkable that Gaudi developed his architectural designs as unique magic naturalism based on his imagination. And In this century 'Regional Culture' gets more important in architectural designs. Gaudi's architectural works can be appreciated to represent very well $Catalu\tilde{n}a$ regional cultural identity by using properly its natural motives and objects.

Jeddah Tower will be the first man-made structure to reach a kilometer in height upon its completion in 2019. From conception, it was clear that an all-concrete superstructure would present many advantages for a building of such unprecedented height and slenderness. An all-concrete structure, however, did present many challenges that needed to be addressed in the system arrangement and through comprehensive analysis and design, among them vertical shortening effects due to the time-dependent creep and shrinkage of concrete. This paper outlines and presents the engineering solutions developed by the authors regarding this complex concrete material phenomenon, while addressing the construction and regional challenges associated with realizing a concrete tower of this unprecedented scale.

The smart sensor technology has opened new horizons for assessing and monitoring structural health of civil infrastructure. Smart sensor's unique features such as onboard computation, wireless communication, and cost effectiveness can enable a dense network of sensors that is essential for accurate assessment of structural health in large-scale civil structures. While most research efforts to date have been focused on realizing wireless smart sensor networks (WSSN) on bridge structures, relatively less attention is paid to applying this technology to buildings. This paper presents a decentralized damage detection using the WSSN for building structures. An existing flexibility-based damage detection method is extended to be used in the decentralized computing environment offered by the WSSN and implemented on MEMSIC's Imote2 smart sensor platform. Numerical simulation and laboratory experiment are conducted to validate the WSSN for decentralized damage detection of building structures.
