| Abstract | Nowadays, the existing building consume high energy of electricity, these cause from
design and construct building with low performance of building envelope (high OTIV), low
efficiency of lighting power system and low performance of air conditioning system. The new
building which coming construction can conserve energy easier than existing building case by
design building in highest energy efficiency which technology available nowadays. The existing
building can conserve energy by retrofitting which complicate more than new building. A method
for energy conservation for existing building need to set up in order to easily to take them to
apply for another existing building case.
To set up A method for energy conservation for existing building, the Library and
Regional Document Center (LRDC) building is to be selected for study case. The LRDC building
is separated into different types area on their function and energy audit has done on those area. In
this study, the Overall Thermal Transfer Value (OTIV) concept base on Thai standard has been
used.
To approach data need for energy conservation for existing building, the monitoring
methodology has been applied. The monitoring process for LRDC building has two level : First,
the main-end use load measurement and other data need measurement : Second, the walk through
audit. After all data is collected, the model energy consumption and standard energy consumption
have been created. From the model energy consumption found that existing annual energy
consumption less than standard recommended 49.5 MWh which from analysis found that lighting
power density and Roof-Thermal Transfer Value (RTIV) less than standard recommendation.
The sensitivity analysis has been conducted to test the level influence of each variable to
total energy consumption for each space area. The opportunity and sensitivity analysis are used to
be first decided to selected variables for improve energy efficiency of LRDC building. In this
study, the Wall-Thermal Transfer Value (W-OTIV), Roof-Thermal Transfer Value (RTTV) and
Lighting Power System (LP) are to be selected for improvement.
The technical analysis has been used to analyzed the feasible options to retrofitting
building and proven the feasible amount annual energy saving. The economic analysis and
economic sensitivity analysis are used to be judged the level attractiveness for each option
improvement then the recommendation to retrofitting the building can be carried out.
After improved OTIV, RTIV and LP, the annual energy consumption of LRDC building
decreased from reference case 131.27 MWh or 9.51 % of total energy consumption can be saved.
The energy index after improvement is reduced to be 196 kWh/m2/year while the existing amount
is 216 kWh/m2/year. |
