The performances of the building service equipment relay on the individual superintendent's share for the assessment of performance, fault detection, deterioration diagnosis of the building service equipment. A major use of building energy management system(BEMS) is for monitoring plant and building's energy consumption. National building management system (N-BMS) presented in this study links buildings into a network group in order to monitor and control the buildings. How to construct the N-BMS was considered to save energy resource and to conserve performance of building service equipment. The FEMIS, facility, energy/environmental management & information system, for building service offer management process integrated with BAS, FMS and EMS and so on.

For the past decade, South Korea had experienced catastrophic building fires, which resulted in consider-ably high number of casualties. This motivated research to develop fire-safe wall assemblies. In this study Fire Risk Analysis (FRA) is conducted as part of the project designing phase to ensure fire safety of the final product. Traditional approach was to consider fire performance at the end of the designing stage, when PASS/FAIL fire test results are required to be submitted to the Authority Having Jurisdiction (AHJ). By applying a fire risk analysis to guide the designing phase, overall fire safety of a wall assembly can be achieved more systematically as conducting FRA allows designers to clearly identify elements that are more vulnerable to fire and simply replace them with other practical options. Severity of fire risk is determined by considering the fire hazards of a wall assembly such as the exterior layer, insulation, vertical connectivity, and external ignition sources (e.g., photovoltaic panels). Frequency of fire risk is assessed based on the factors affecting fire likelihood, which are air cavity and fire-stopping applied in the design, and random design changes occurring during on-site construction. Fire risk matrix is proposed based on these fire risk factors and efforts to reduce the fire risk level associated with the wall assembly are given by systematically assessing the fire risk factors identified from fire risk analysis. Current study demonstrates how fire risk analysis can be applied to develop fire-safe walls by reducing the relevant fire risks- both severity and frequency.

Composite panel refers to the particular plywood produced in a way of stacking the different kinds of material in sandwich form and adhering them using adhesives and is widely used as building material for its constructability and cost efficiency. But as the surface is finished with steel plate, fire extinguishing agent cannot reach to the core material because of such steel plate on surface which causes the difficulties in suppressing the fire as well as in fire-fighting activities due to collapse. This study, to deal with such problem, is intended to set the fire pipe in core material to prevent the fire from spreading and in a bid to achieve this using minimized fire water, water supply test device was fabricated to estimate the required water flow of fire extinguisher and consequently, optimal water flow (0.5 L/min) was determined through a full-scale fire test.

As a building energy saving standard strengthened, The number of building installed external thermal insulation composite system(ETICS) using EPS insulation increased. But frequent fire accident in the buildings installed EIFS using EPS led to strengthening of building fire safety regulation. This study is for fire property of EPS ETICS reinforced with noncombustible calcium silicate-based mineral insulation as a fire spread prevention structure(FSPS). Fire test for large scale wall by ISO 13785-2 was applied and results showed EPS EIFS with FSPS got 3~8 times superior fire safety than normal EIFS by visual investigation. Temperature and heat flux measurement results, which data of upside of specimen were lower than downside, also supported fire safety of EIFS with FSPS.

In this study, strengths related with fire investigation of fire stations are analyzed and methods for the capacity building of their fire cause investigation are suggested. The methods for capacity building of fire cause investigation suggested are focused on using potential and strengths of current fire fighting and enhancing internal capacity rather than reinforcing investigation personnel, organization, and equipment and ensuring investigation power. The methods suggested in this study are as follows. 1) Because fire investigation results are the basis of fire administration, fire marshals should change their awareness of the need of fire investigation; 2) A fire investigation system should be established to ensure statements of people concerned systematically; 3) A substantial system of fire cause investigation should be established to investigate fire scenes more than twice; 4) A substantial system of fire cause investigation should be established to use such materials as CCTV; 5) Extinguishing should be made in consideration of fire cause investigation and a scene preservation system after extinguishing should be established; 6) A fire investigation system should be established in connection with 119 first-aid and rescue teams and 7) Steps to raise the morale of fire investigation staff should be taken.

In this study, fire resistance tests were conducted to evaluate the fire resistance performance of unprotected and non-welded CFT columns in relation to the shape and size of cross-sections. Unprotected slot-type CFT columns which were ${\square}300$ and ${\square}500$ in dimensions resisted fire for 125 minutes and more than 180 minutes, respectively. Strain analysis showed that slot-type CFT columns were more ductile than welded CFT columns. The temperatures of central parts measured when welded CFT columns and slot-type CFT columns had lost fire resistance performance were higher in the former than the latter. Therefore, slot connection does not a great influence on the temperatures inside the concrete.

Pilotis are support columns that lift a building above the ground. Thus, they can elevate the lowest floor to the secondfloor level and, in Korea, are used to leav a parking area below multifamily housing. However, if there is a fire in the piloti area, the cars and main entrance door are wrapped in flames. Due to the inflammability of the materials, the combustion of the cars and insulation at the ceiling of the pilotis, having a high heat release rate, can quickly destroy the front entrance of the building and spread heat, flames and a poisonous gas to the stairs and elevator pit. Therefore, the fire can quickly spread to the whole building, putting the lives of the residents in danger. This study was an in-depth accidental case study of the "Uijeongbu Fire Accident" that killed 5 residents and injured 139 others. The study identified the relationships between the fire at the piloti structure of multifamily housing and the vulnerability of this structure and its inherent weaknesses.

Owing to increase of the large-scaled, high-raised and complexed building construction, the escape design of the building became very important issue to insure the safety of occupant. Specially, it is demanded to have building escape regulation considering for inconvenient movers such as disables elders pregnant women. However, building regulations for inconvenient movers are divided into "Regulation of Escape and Fire-prevention of Building" and "Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information". But, for the escape security of inconvenient movers, the connection of each regulation are necessary. So this study suggested the improvement direction of the building escape regulation considering inconvenient movers through the compared analysis on the "Regulation of Escape and Fire-prevention of Building" and "Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information".

Recently, a large fire has occurred through a dry bit, which is a flammable exterior material, in Daebong Green Apartment Fire in Uijeongbu in 2015 and Jecheon Sports Center Fire in 2017. In this study, KS F ISO 5660-1 Cone calorimeter experiment was used to examine the fire risk of dry bit. Also, the performance of the repair and reinforcement materials to prevent fire expansion was examined. As a result, the dry bit is likely to be ignited by internal and external flower gardens, and its combustion rate and calorific value are very high. In addition, the performance of heat resistance such as ALC panel and ceramic board as a repair and reinforcement material has been proved. However, the insulation is expected to require further consideration.
