1. Introduction and analysis of the subject of the course. Environmental impact of the construction sector. Production of building materials (BM) and environmental footprint. Applications and use of BM and correlation with environmental cost. Participation of production and use of BM in climate change. Service life of structures. Methods and tools for environmental cost (EC) assessment. Directions for reduction of total environmental cost and current trends. Terminology.
  1. Life cycle analysis (LCA). The LCA methodological framework. Definition of goal and scope. Life cycle inventory. Environmental impact assessment. Interpretation. LCA software tools. Evaluation and certification systems for sustainability of buildings (BREEAM, LEED, etc.).
  1. Estimation of service lifetime. Durability of building materials. General mechanisms for reducing the durability of building materials and structures. Common mechanisms for reducing the durability of reinforced concrete. Service life estimation through prediction models.
  1. Environmental cost. Fixed environmental cost (EC). Operational environmental cost. Total environmental cost. EC calculation and optimization. Review of regulations and guidelines for sustainable construction.
  1. EC reduction techniques and materials. Principles of circular economy and industrial ecology. Design and brief reference to industrial building systems with the possibility of disassembly / reuse. Use of supplementary cementing materials and industrial products in construction (“green” substitutes for conventional building materials: fly ash, slag, biomass ash, etc. – current situation in Greece). Recycling of construction and demolition waste (CDW) and legal framework. CO2 capture in construction and mitigation of climate change.
  1. Application examples and case studies. Calculation of service life of specific concrete structures made of reinforced concrete. Application of LCA in specific building materials and structures. LCA as part of policy making during the design phase. Implementation of certification systems for the viability of projects and buildings (BREEAM, LEED, etc.). Use of specific industrial by-products in construction. Proposals for the recycling of specific CDW streams (recycling of concrete, bricks, plasterboard, etc.).
