Basic Concepts of Sustainability in Engineering

Flashcards covering key concepts related to sustainability in engineering and construction, derived from lecture notes.

Sustainability

Development that meets present needs without compromising the ability of future generations to meet their own needs.

Intergenerational Equity

The principle that present generations should manage resources in a way that does not compromise the ability of future generations to meet their needs.

Embodied Energy

The total amount of energy required to extract raw materials, process them, manufacture construction products, transport them to the building site, and install them in a structure.

Operational Energy

The energy consumed during the use phase of a building, including heating, cooling, ventilation, lighting, and appliance usage.

Life Cycle Costing (LCC)

An evaluation method that assesses the total cost of a building over its lifetime, incorporating initial, operational, maintenance, and end-of-life costs.

Three Pillars of Sustainability

The interconnected dimensions of sustainability: environmental sustainability, social sustainability, and economic sustainability.

Circular Economy Concept

A model that aims to minimize waste and maximize resource efficiency by keeping materials in use for as long as possible.

Environmental Sustainability

Focus on reducing ecological impact through minimizing carbon emissions, conserving resources, and protecting ecosystems.

Social Sustainability

Focus on human well-being and quality of life within the built environment, ensuring health, safety, and accessibility for all.

Economic Sustainability

Focus on the long-term financial performance of a building, ensuring it remains viable throughout its entire lifespan.

Operational vs Embodied Emissions

Operational emissions are the carbon emissions associated with the operation of a building, while embodied emissions arise from material extraction and construction processes.

Urbanization and Infrastructure Pressure

The increased demand for housing, transportation, and other services resulting from rapid population growth in urban areas.
