“…This situation requires comparison in choosing the one that maximizes cost savings (Fuller, 2006). The LCCA analytical approach assists in the discovery of the most economical option that fulfills the project objectives and contributes essential data to the overall decision-making process (Hatami & Morcous, 2016) (Liu, 2015).…”

Currently, the Indonesian government continues to encourage the realization of sustainable development. The green concept is a sustainable development trend in the construction material industry. The concrete industry plays a vital role as a supplier of concrete materials in construction, so its availability is essential. The role of concrete industry itself has a negative impact on the environment. Stakeholders increase the cost of green retrofitting so that the industry or building becomes eco-friendly. The research method was carried out using a process case study, namely, how to implement green retrofitting cost performance in the concrete industry using Value Engineering and Life Cycle Cost Analysis. Theoretically, the research results provide additional knowledge for academics; practitioners can provide problem-solving to get an overview of the implementation of the green concept in the industry regarding the flow of implementation and the benefits of savings in an environmentally friendly production process. The application of value engineering in the green retrofitting of the concrete industry has increased the cost performance of green retrofitting by 8.66% with a return of 3 years and 8 months and increased the functions and benefits of an eco-friendly and sustainable concrete industry

“…Tujuan utama pada tingkat hierarki pertama yaitu bangunan rumah sakit hijau yang menyediakan ekologi, hemat air, hemat energi, pengurangan limbah dan lingkungan yang sehat bagi pasien dan staf [20]. LCCA deterministik adalah metodologi tradisional di mana pengguna menetapkan setiap variabel input (misalnya, masa pakai, periode analisis, tingkat diskonto, waktu dan biaya kegiatan pemeliharaan) nilai tetap yang biasanya didasarkan pada data historis dan penilaian pengguna [21].…”

Di Pekerjaan Rumah Sakit yang berkonsep Green, ada beberapa ketentuan yang harus dipatuhi bahwa semua proses baik material yang dipilih, metoda pelaksanaan maupun operasional bangunan harus mengacu pada kaidah Green. Dengan menggunakan metoda Value Engineering (VE) kemudian Life Cycle Cost Analysis (LCCA), peneliti mencoba menerapkan konsep Green Hospital pada proyek yang menjadi studi kasus namun tetap berbiaya efisien bahkan lebih rendah dari Rencana Anggaran Biaya (RAB) awal. Untuk mengetahui pengaruh kedua metoda efesiensi biaya terhadap proyek green hospital, peneliti menyebarkan kuesioner kepada para stakeholder , hasil dari kuesioner tersebut dikumpulkan, diolah dan dianalisis menggunakan SPSS Ver. 21.0. Ternyata bahwa penggunaan metoda VE dan LCCA ini sangat berpengaruh dalam meningkatkan kinerja biaya. Dari kesimpulan yang ada metoda LCCA menunjukkan pembayaran kembali (Payback Period) untuk Pembangkit Listrik Tenaga Surya dengan waktu = 9,64 Tahun ≈ 9 Tahun 7 Bulan, Pemusnah Limbah B3 dengan waktu = 4,28 Tahun ≈ 4 Tahun 3 Bulan.

“…In a probabilistic analysis, the input parameters are stochastic variables based on assumed or documented mean and standard deviation values, and distribution function. Typically, probability distribution functions for the variables considered in the analysis are performed through Monte Carlo simulations (Hatami & Morcous, 2015). The random sampling model generally includes thousands of iterations that ultimately generates a probability distribution of the maintenance costs.…”

Reinforced Concrete (RC) and Prestressed Concrete (PC) structures using conventional materials in aggressive exposure conditions are susceptible to corrosion. Non-corrosive reinforcement materials such as: Glass Fiber-Reinforced Polymer (GFRP) rebars; Carbon Fiber-Reinforced Polymer (CFRP) strands; Stainless-Steel (SS); and Epoxy-coated steel (ECS) reinforcing bars, are attracting attention as more appropriate options in concrete structures. This paper addresses a Life Cycle Cost (LCC) analysis that verifies the cost performance of four different alternative reinforcement bars for the design of a demonstration FRP-RC/PC bridge in Florida, namely Halls River Bridge (HRB). The four different alternatives to be compared are namely Carbon Steel (CS), SS, FRP, and ECS, and the analysis is performed over 100-years. Additionally, a Life-Cycle Assessment (LCA) is included in the analysis to investigate the environmental credentials of the four design alternatives. Cost sensitivity analyses over specific parameters are included. The parameters analyzed are: reinforcement cost, changes in chloride concentration levels over the bridge service life, and discount rate values. Conclusions and recommendations for standard practices and design of future alternative solutions are then presented.
