The purpose of this study is to analyze the biotope characteristics of Korean cities and set up biotope type structures for Korean cities based on biotope type classification, dominant biotope type, city's human and nature environmental characteristics and cluster analysis. The findings of the study are summarized as follows: First, regarding the analysis of biotope type classification, cities showed differences in terms of the standard of biotope classification and classification hierarchy. Next, the analysis of dominant biotope types showed the type of forest represents the largest area in most cities. Moreover, a city's characteristic analysis revealed large differences between cities. As a result of cluster analysis, cities were classified into five clusters overall. First, Cluster A showed a lower population level and urbanization level. Unlike other cities, Cluster A revealed that it has the largest percentage of agricultural areas. Cluster C showed very high levels in terms of population amount and urbanization conditions was named the 'Large-sized metropolitan cities-center of forest biotope area' based on it's characteristics. The findings of this study as summarized above are considered to play an important role in enabling detailed classification and preservation of biotope types fit for the characteristics of cities and minimizing the confusion caused by different biotope mapping methods when revising and complementing biotope maps.

The objective of this paper is to show the possibility of demand-controlled ventilation(DCV) using the Korean ventilation standard for apartment houses. A numerical model for predicting realtime occupant number and CO₂ concentration under given conditions is developed using a commercial equation solver program. It is found that the current ventilation standard causes unstable ventilation system control in DCV application under CO₂-DCV. It is because the ventilation rate(per person) used in Korea is the sum of the outdoor air required to remove or dilute air contaminants generated by both occupant and building itself. It is found that current Korean ventilation standard modified as a form of ASHRAE standard enhances applicability of the current ventilation standard to the DCV approach.

A dedicated outdoor air system (DOAS) comprised of enthalpy wheel, cooling coil, sensible wheel and supply/exhaust fan is able to decouples ventilation and air-conditioning functions and/or sensible and latent load functions. It removes the entire latent load and a portion of the sensible load inside a conditioning zone using 100% outdoor air ventilation. The remaining sensible load is accommodated by a parallel mechanical cooling system. According to the literature, a DOAS based centralized ventilation system shows good potentials for using in high-rise multi-family houses. The main object of this paper is to develop a simple computer program which can be used in the preliminary design phase of a DOAS applied to high-rise apartment buildings.
