Life Cycle Assessment (LCA) adalah metode penilaian siklus hidup dalam suatu produk. Dalam arsitektur, penggunaan LCA masih terbilang cukup baru. Sebagai seorang arsitek cukup untuk memahami LCA melalui teori LCA yang disederhanakan. Penerapan LCA dalam industri bangunan dapat berupa mengevaluasi proses manufaktur, membandingkan beberapa material dan metode, serta menganalisa suatu bangunan secara keseluruhan. Teori-teori LCA yang disajikan dalam skripsi ini menjabarkan jenis-jenis dan metode-metode LCA yang berbeda. Terdapat teori secara sederhana bagaimana LCA dihitung. Definisi arsitektur dijelaskan agar mendapatkan keterhubungan LCA dalam arsitektur. Studi kasus yang diambil berupa perbandingan GWP (Global Warming Potential) material-material yang sudah dapat dibandingkan secara apple-to-apple.

Life Cycle Assessment (LCA) is an assessment of the life cycle of a product. In architecture, the use of LCA is still quite new. As an architect it is enough to understand LCA through simplified LCA theory. The application of LCA in the building industry can include evaluating manufacturing processes, comparing several materials and methods, and analyzing a building as a whole. The LCA theories presented in this thesis describe the different types and methods of LCA. There is a simple theory of how LCA is calculated. The architectural definition is explained in order to get LCA connectedness in architecture. The case study taken is in the form of a comparison of the GWP (Global Warming Potential) of materials that can be compared apples-to-apples.
