Knowra Sustainable architecture Sustainable architecture Sustainable architecture designs and constructs buildings to reduce environmental harm while supporting occupants’ health and long-term social and economic needs.
Passive solar building design : Building design that uses orientation, glazing, shading, and thermal mass to manage solar heat and daylight. It reduces heating and lighting demand through form and placement rather than mechanical systems.
Energy efficiency : The reduction of energy required to provide a given service or level of performance. It is a central building target, though it does not capture every sustainability concern.
Earthship : A building type designed to provide shelter and utilities through passive solar principles and on-site resources. Earthships combine passive heating, water collection, and reused materials in a recognizable building approach.
Life-cycle cost analysis : A method for comparing costs incurred over an asset’s expected life, including purchase, operation, and maintenance. It can justify higher upfront costs when a design reduces later expenses.
Building envelope : The physical boundary between a building’s interior and exterior, including walls, roofs, windows, and foundations. Its insulation, airtightness, and solar control strongly shape energy use and comfort.
Renewable energy : Energy from sources replenished on human timescales, such as sunlight, wind, and geothermal heat. On-site or grid-supplied renewables can lower buildings’ operational emissions.
Passive house : A building standard emphasizing very low energy demand through airtightness, insulation, heat recovery, and careful design. It demonstrates a measurable route to reducing operational energy while maintaining comfort.
Value engineering : A structured method for improving a project’s function relative to its cost. Cost reduction can support or undermine sustainability, depending on which functions and impacts are prioritized.
Life-cycle assessment : A method for evaluating environmental impacts across a product’s or system’s life cycle. It compares building choices beyond initial construction, including material production, operation, and disposal.
Circular economy : An economic model that reduces waste by keeping products and materials in use. Its reuse principles challenge the one-way extraction and disposal of construction materials.
