Project Details


A building energy profiling tool was developed to establish benchmark performance data for office buildings in Seoul with the focus on buildings of 3,000 to 10,000 m^2 floor area. Benchmark data are usually defined on the basis of actual energy use. Small-to-medium size buildings, unlike large buildings, are unlikely to have energy monitoring systems and therefore data availability will be poor. The project addressed this issue by developing an energy profiling tool, which exploits monitored and simulated data sources.

ESRU applied building simulation to establish disaggregated energy profiles for office buildings as existing and with a range of alternative design modifications applied. These synthetic profiles were encapsulated within a database management application (alongside monitored data) to enable users to produce energy performance benchmarks for existing buildings and proposed retrofits.

A modelling procedure was developed that is able to automatically generate models that represent large building stocks (e.g. at the district or city scale) differentiated by principal design parameter values (level of insulation, system efficiency, hot water usage etc.).

Design information on approximately 2000 buildings in Seoul was collected through literature review, site visits, and interactions with local agencies; and monthly gas and electricity consumption data obtained over a two-year period.
These data allowed the major design parameters impacting building energy consumption and their typical levels to be identified for use to generate models representing the entire building stock.

The ESP-r system was then used to generate ‘ideal’ hourly load profiles for heating, cooling, lighting, appliances, ventilation, hot water, and elevators. Disaggregated profiles were then encapsulated in a new database tool for use to assess the performance of existing buildings and identify opportunities for improvement..
