The quality of apartment houses has been gradually upgraded. However the changes in demographic composition of residents such as seniors, disabled persons, and etc. have not been considered in the process of planning. If apartment houses are designed on the base of the concept of universal design, their residents could live as long as they want to live in. This study evaluates the Korean standard-sized apartment housing units and the common spaces of those apartment buildings, and it's outdoor environments from the perspective of universal design. The observation and measuring was conducted with the questionnaire survey with 100 residents living in those housing units. 60 items were designed for evaluating them in relation to the principles of universal design. The results are as follows : 1) In general, the principles of universal design were relatively applied to the apartment houses. However their application needs to be broadened. 2) The number of parking lots needs to be increased and the width of individual parking lot to be increased. Also, the location of gazebo and senior center needs to be placed in easily accessible areas. 3) The shape, color, finishes of the ramp and the entrance area of the apartment building and housing unit should be made more homelike. Also, the entrance area of apartment building and housing unit needs to be made large enough for residents themselves and meeting with neighbors. 4) Among all of the rooms in a housing unit, bathroom should be improved immediately. Also, the width of doors should be at least 80cm wide and the floor should be made even.

In Korea, the construction company has provided houses through apartment sales system. Residents have obtained a variety of information about their future house by visiting a sample house called "the model house" before they purchase home. Advanced technology such as web-based VOD or Virtual Model in recent years has gradually replaced those built environment. In 2009, the Ministry of Land, Transport and Maritime Affairs announced the restraint to the construction of sample houses. Instead, they highly recommended a Virtual Model House as an alternative solution. This study aimed to propose how to design the user-oriented virtual model house through the experiment and survey research. The 3D virtual model house of 85m$^2$ apartment was built and presented by two types (Type A: Bird's Eye View, Type B: Walk through View) on the web page. The subjects evaluated presence, spatial perception and cognition, and usability of each type after exploring them. The results are as follows. (1) The subjects' evaluation of presence showed Type B has more negative effects than Type A such as feeling dizzy or tired even if their values were not so high. (2) The subjects perceived and cognized both types of virtual model house more realistic for the expression of volume of space, the size of opening, and the arrangement of furniture than that of wall finishes and materials. (3) The usability of Type A was significantly higher than that of Type B.

Technology has been viewed at various stages of civilization as leading to future progress. The building, its services systems and management of the work process all contribute to the well-being of people within an organization. Productivity relies on there being a general sense of high morale and satisfaction with the workplace. Now buildings are considered as providing a milieu for human creativity. Flexibility, adaptability, service integration and high standards of finishes offer an intelligence threshold. Building Automation System(BAS) - controlled lighting systems may offer incremental energy saving. Conventional Lighting control systems often control equipment in a single room or over the limited area, because they are centralized control systems, which means that all the controlled circuits must be wired to a single control panel. The computers used by these systems are typically dedicated microprocess that perform only lighting control functions. By comparison, modern Building automation systems are distributed control system, which means that their computing hardware and software are distributed as a network that microprocessor-based control modules and standard PC. PLC(Programmable Logic controller) is extensible virtually without limits, so that all the lighting in a facility can be controlled by single, unified system - the same system that also can control and monitor the building's HVAC, security, and manufacturing processed, elevators, and more. A Building automation system can control light using schedules, manual controls, occupancy sensors, and photosensors, either singly or in combination. Building Lighting control and monitoring system will be for a energy saving and efficient building management system.

The purpose of this study was to carry out POE of assisted living housing and suggest the design guidelines for the housing complex for the elderly. The subjects were residents(old persons) and staff who lived or worked in three assisted living housing in Cincinnati, Ohio. Interview and survey method using questionnaire were used. The design guidelines for the housing for the elderly were suggested as follows: 1) the location of the housing for the elderly should be in or near the existing housing area, 2) the arrangement of spaces of the housing for the elderly should consist of small groupings rather than large and long corridor pattern, 3) the number of the housing units for the elderly should be small, under 100 units, 4) the housing units should be used by one older persons so that she/he could have the chance of privacy and personalization, 5) various common spaces such as art and craft room or game room should be provided, 6) accessibility should be considered, 7) the color and patterns of interior finishes should be differentiated according to floors or spaces and familiar ones should be used to make a homelike environment.

Recently, the construction industry has seen the emergence of interior and exterior finishes using ultra-high performance concrete (UHPC) and colored concrete products using precast concrete (PC). However, the excessive amount of pigment used for coloring reduces the strength of the concrete. There is a need to improve the durability and chromaticity of colored concrete, and further analytical studies on the properties of colored concrete are also required. Therefore, in this paper, colored ultra-high strength cement composites (C-UHSCC) containing red and green inorganic pigments were prepared, and the compressive strength and color of the specimens were measured according to the age, and the correlation between strength and color was analyzed by simple linear regression analysis using R² value. The results showed that the red color was highly correlated with L^* and a^*, and the green color was highly correlated with a^*. These results can be considered for various concrete formulations, but research is needed to suggest the optimal pigment mixing ratio for proper strength and color development.

Although the use of BIM in architectural projects has increased, repetitive modeling tasks and frequent design errors remain as obstacles to the practical application of BIM. In particular, interior finishing elements include the most varied and detailed requirements, and thus requires improving its modelling efficiency and resolving potential design errors. Recently, visual programming-based modules has gained traction as a way to automate a series of repetitive modeling tasks. However, existing approaches do not adequately reflect the practical modeling needs and focus only on replacing siimple, repetitive tasks. This study developed and evaluated the performance of three modules for automatic detailing of walls, floors and ceilings. The three elements were selected by analyzing the man-hours and the number of errors that typically occur when detailing BIM models. The modules were then applied to automatically detail a sample commercial facility BIM model. Results showed that the implementations met the practical modeling requirements identified by actual modelers of an construction management firm.

This study is on the general characteristics of 'Monolithic' architecture. The intentions of monolithic architecture can be assumed as an attempt to replace the formal looseness or difficulties of understanding formal complexity of modern architecture, or a trial to react against contemporary avant-garde architectural tendency typically characterized as unstableness, uncertainty, fluidity, and articulation to reestablish autonomy of architecture. Buildings in this category coincide in their extreme economy and simplicity of overall form and consistency of external appearance while showing great expressional capacity with very limited formal means. Even though monolithic architecture still seems a little unstable and ambiguous in historical aspects, it can be considered as strikingly shaped objects or autonomous forms with identities, logics, and representation that promote recognition. Using architectural techniques of scale, colors, materials and finishes, monolithic architecture shows strategically invested surfaces that mediate between the inside and the outside, and shows unexpected and mysterious autonomy. This kind of monolithic approach is also found in interior space as a separate objects that contain functional space inside, or as formal elements that overflow the boundaries of conventional architecture by eliminating the distinction between floor, wall, and ceiling.

Increasing green house gas and it consequent climate change problems are discussed as a global issue. Accordingly, future local green house gas emission will increase up to 40% of the entire local green house gas emission and therefore, efforts to reduce the emission in construction industry is urgently required. Therefore, in this study, heating energy demand was analyzed by using the EnergyPlus simulation according to wood material finishes configuration. EnergyPlus has the entry for a variety of buildings and heating, ventilation, air conditioning (HAVC) system components, in particular buildings, air conditioning systems, and performs simultaneous integrated calculated through the feedback between the heat source unit, a verification program according to the ASHRAE Standard 140-2007 to be. The climate data for the simulation we used the data IWEC in Incheon and Gwangju provided by EnergyPlus. The analysis of simulation model was farm and fishing house standard design drawings: 2012, presented at the Korea Rural Community Corporation. The results of simulation of central region and southern region were effected by wood products of simulation model into the interior finish, exterior finish, windows, wooden structure. Also, it was confirmed that the reduced heating energy demand.
