It has been a serious problem to consume the energy of apartment while increasing to use of heating & cooling System because of residence environmental upgrades. Great attention has been shown to the problem of the rental apartment, so there are few reports of energy consumption about the rental apartment in korea. To solve the lack of housing, our country has supplied an enormous volume of apartments, and these days it occupies 75% of our buildings. As apartments occupy most of our housings, the rate of energy usage from them are also high. On this, setting apartment energy reduction as a target, by researching the actual conditions of energy consumption and drawing a basis data, we can apply this as a way of saving energy, rationalization of the scale of energy supply facilities and a standard when planning facilities. To grasp the present condition of energy usage of the urban rental apartment, this research analysed the use of electricity, gas and water monthly and annually of a rental apartment that is located in Daegu. The results showed that in 2003 the electricity usage was 1,198MWh but 1,315MWh in 2007, which means 9% of electricity usage increases every year. The average of water usage was $85,072\;m^2$ per year and typical energy consumption unit was $604.2\;MJ/m^2$ on $74.4\;m^2$ of area and $448.8\;MJ/m^2$ on $105.8\;M^2$. By showing the usage of energy and water of the urban rental apartment, understanding the tendency and preparing an typical energy consumption unit standard through this research, apartments should use energy more efficiently.

It has been a serious problem to consume the energy all around the world while increasing to use of heating & cooling system because of residence environmental upgrades. Previously used to use electricity more efficiently will be very important. If the peak load can be reduced on the most common use of electricity in peak time, that could significantly reduce fossil fuel to Consumed producing electricity. On this, setting household energy reduction as a target, by researching the actual conditions of electricity consumption and drawing a basis data, we can apply this as a way of saving electricity, rationalization of the scale of energy supply facilities and a standard when planning facilities. Most of basis data was collected by field survey. And it will also help to create a load profile. By showing the usage of electricity understanding the tendency and preparing load profile standard through this research, household should reduce peak-load during daily life.
