Windows energy saving design of residential buildings has increasingly got the attention of people. Through a large number of surveys and analysis of residential buildings in Chongqing and consumers personal experience, the author finds problems and deficiency, and then proposes principles of residential buildings sun shading reconstruction in Chongqing city. Taking the high-rise residential building of one university in Chongqing as reconstruction sample, selecting a specific time period, the author recalculates sun shading coefficient with and without sun shading by using Ecotect software to do simulation analysis. Finally, the reasonable reconstruction design pattern is put forward through cases. Keywords: Buildings Sun Shading, Sun Shading Reconstruction, Energy Saving

Reducing Energy

In connection with the large-scale development of high-rise building projects recently in Russia and abroad and their significant energy consumption, one of the main principles in designing is the use of effective energy-saving technologies. Also, important aspects are reducing energy consumption and neutralizing the environmental impact of tall buildings. The most promising areas in the field of integration of solar modules (planar and concentrating) in the construction of buildings are development of BIPV technologies (roofing, film, facade materials), the integration of solar energy concentrators that do not require biaxial tracking (medium and low concentrations) on the facades and roofs of buildings (parabolic concentrators, lenses, and Fresnel mirrors), integration of highly concentrated modules on the roofs of buildings.

Through comparative research between actual projects in steel structure residence system of Hangxiao Steel Structure Co., Ltd.(shorted for “HXSS”) and comparative models in terms of land saving, material saving and energy saving, the performance of steel structure residence system in dealing with environment, environmental protection and saving is analyzed. The comparison results show that the steel structure residence system has certain advantages, however the performance in energy saving, particularly in consumption of building material transportation needs further improvement.

Elevators- means of vertical transportation to carry people and goods are an indispensable part in offices, high-rise buildings, hospitals, commercial areas, hotels, car-parks when blooming urbanization develops worldwide. However, the level of energy consumption in elevator operation is significant, so energy saving solutions have been outlined and applied in practice. With frequent braking phases, regenerative braking energy is wasted on braking resistors. Therefore, this paper proposes regenerative braking energy recuperation method for elevator operation in building by active rectifiers enabling the braking energy to be fed back into utility grid. Simulation results conducted by MATLAB with data collected from OCT5B building-RESCO new urban area, Ha noi, Vietnam have verified saving energy of using active rectifiers replacing diode rectifiers up to 33%.

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.
