Energy cost is significant in many of the manufacturing activities. The efficiency of energy use is quiet low as there are substantial visible and hidden losses. Visible losses can be easily identified and corrective action can be taken. However hidden and indirect losses form a sizeable portion of the losses. Identifying these losses is not easy and requires an integrated approach which includes thorough study of process, operations and their interactions with energy use. Industries across sectors have implemented lean management principles which target various wastes occurring in the plant. This paper discusses case studies which highlight the exploitation of lean tools as a means for unearthing hidden energy saving potential that often go unnoticed. In addition to the energy savings which results in improved profits and competitiveness, the approach also aids the industry to pursue a path of sustainable manufacturing.

As the major public buildings and cultural service institutions, libraries play an important role in the strategy of energy-saving buildings. In order to keep pace with the footstep of Western developed countries, China has launched a series of green and energy-saving building practices and achieved certain results. The New Hubei Library is a successful example, with Chinese national conditions and the characteristic of the library itself taken into consideration, and limited conditions in the design process fully made the most use of. Besides the designer has efficiently used energy-saving strategy on building structure maintenance, solar radiation, air conditioning control system and natural ventilation, finally achieved the goal of energy saving of library.

Abstrak: Tujuan studi ini adalah membandingkan perhitungan potensi penghematan energi tanpa memperhitungkan efek interdepensi dengan perhitungan potensi penghematan energi dengan memperhitungkan efek interdependensi berdasarkan studi kasus pada bangunan gedung terkondisikan. Estimasi potensi penghematan energi yang akurat akan menghasilkan proyek konservasi dan efisiensi energi yang bankable akan meningkatkan kepercayaan terhadap investasi proyek – proyek penghematan energi. Hal ini  akan meminimalkan ketidakpastian penghematan energi yang dapat dicapai serta meningkatkan potensi untuk mencegah risiko investasi dari  implementasi proyek – proyek konservasi dan efisiensi energi. Hasil dari studi ini menunjukkan bahwa terjadi kenaikan estimasi penghematan energi sebesar 4,29% pada ESM-1 yaitu retrofit tata cahaya dan kenaikan estimasi penghematan energi sebesar 22,75% pada ESM-2 yaitu pemasangan VSD pada AHU. Pengaruh interdependensi tersebut adalah adanya pengurangan cooling load pada bangunan gedung karena efek interdependensi pada ESM-1 dan ESM -2.  Secara total perhitungan efek interdependensi akan meningkatkan prosentase total estimasi potensi penghematan energi dari 34.23% menjadi 39,05% berdasarkan baseline energi dengan baseyear yang telah ditetapkan atau meningkat sebesar 4,82%. Perhitungan efek interdependensi akan sangat berpengaruh untuk meminimalisasi ketidakpastian apabila proyek proyek konservasi dan efisiensi energi dibiayai dengan energy performance contract dengan skema guaranteed saving maupung shared saving. Perlu tindak lanjut dari studi ini yaitu perhitungan dan verfifikasi penghematan energi hasil implementasi ESM-1, ESM-2 dan ESM-3 pada tahun berjalan.
