The energy audit program was carried out for Faculty of Engineering Technology (FTK), University Malaysia Pahang by internal energy audit team. This paper presented annual energy consumption trend for FTK building, measurement finding for room data survey (air conditioning temperature and humidity comfort performance & CO2 level for air quality) and lighting, Building Energy Index (BEI) value and appropriate recommendation in regards of energy saving practice and technological solution. According to those analysis, value for Building Energy Index (BEI) in FTK building is 98.035 kWh/m2/year, Air Conditioning Energy Index (ACEI) is 73.254 kWh/m2/year while for Lighting Energy Index (LEI) is 11.402 kWh/m2/year. Total energy consumption estimated for 2017 is 31, 7951.375 kWh per year. The implementation of the proposed energy conservation measures were expected to give positive results where the total cost saving per year is estimated about RM 48,551.20. Finally, it was recommended to implement three major energy conservation measures (ECMs) in specific: implementation of Sustainable energy management system (SEMS), maintenance of air conditioning system and retrofitting of LED lighting. As a result, FTK is targeted to achieve 30% annual energy saving about from the total energy consumption.

Building Energy Saving

Lately Malaysia energy consumption versus generation rapidly shows increasing due to increasing of load. This phenomenon happened following to advanced country development. Lacking on design and without energy management approach the energy consumption and monthly electrical bill will steadily increased and support the increasing of world carbon emission. Therefore the aim of this work is to approach the simplest innovation task-energy audit , which is load-apportioning strategy. This approach using matching the usage of equipment with fully utilized space and reschedules the time of usage. A one week data was collected by logged power meter at main switchboard at selected building using Fluke Power Recorder. From the data collected, current usage of every load can be determine, then load will be arrange into a group with same portion and same time of usage. The result shows clearly the energy consumption for every single day and indicates the highest and lowest peak. From this work the apportioning strategy implemented by rearrange the load following type of room application. After the arrangement, new measurement was taken and a very good result was established. This work also can be further apply for a huge load that can be save a lot of money for owner especially government by energy saving.

Abstract In the hotel business, the use of energy is very important, especially in the use of electricity, the portion of usage and allocation of funds for its provision is the largest. It can be seen that equipment such as lights, elevators, refrigerators, laundry, heaters, pumps, to the air conditioning system are some of the dominant tools in operations in the hospitality world. The results of the initial energy audit and detailed audit at the Grand Clarion Hotel Makassar showed that the Energy Consumption Intensity (IKE) is still far from the standard, which is 300 kWh / m2 a year. The building uses the largest amount of electricity in the Grand Clarion Hotel Makassar in Building A, which is in the Guest Room area of the air conditioning unit. The results of the initial energy audit of Energy Consumption Intensity (IKE) electricity were 336.84 kWh / m2 year. Whereas based on the results of a detailed energy audit the electricity consumption intensity (IKE) of electricity is 395.51 kWh / m2 a year. Energy Saving Opportunities (PHE) in this energy audit is to evaluate the AC power in each room and recommend the replacement of lamp types. From the results of the IKE calculation after the application of PHE, it is found that the value is still quite high so that efforts to save must still be done.

Energy consumption of a building is one of the biggest sources of energy use today. Green Building Comitte Indonesia (GBCI) has launched a concept of energy consumption saving in a nationally standard building. Audit Building energy audit is the way to know how actual building energy consumption is and find alternative solution to decrease energy consumption in order to fulfill the energy saving building criteria. Two types of HVAC systems will be run in the EnergyPlus simulation, split AC and central AC. The previous research proved that central AC is better than split AC system for energy saving in the building with 20 floors. The simulation results show that by using a certain energy system, a more efficient energy system will be achieved and can still maintain the comfort of the room at a temperature of 24 °C and relative humidity according to the Green Building Indonesia standard reference.

The data used in data collection in the form of electricity usage data, building area data and observations made by researchers. Analysis of the data used in this study is to use the formula of energy consumption intensity. The results showed the IKE value of the CB FKIP Untirta building was 254.5 kWh/m2. With these results, it can be seen that the IKE value in the CB FKIP Untirta building is still inefficient. This is based on ASEAN-USAID parameters which range at 240 kWh/m2. Based on electrical energy consumption in the CB FKIP Untirta building there is an opportunity for energy saving or energy saving solutions that are replacing TL lamps with Led lights or by replacing TL lamps that are smaller watts and in terms of air conditioning or air conditioning load replacing R32 refrigerant with R32 refrigerant mixture and The R290 has proven to be quite efficient in terms of savings and energy efficiency. And the duration of use of electrical energy.
