environmental preformance measures Flashcards
What is environmental performance?
A set of factors that can be measured to give an indication of the environmental impact of a building
Environmental performance is essential for assessing sustainability in construction.
What are life cycle assessments (LCAs)?
Evaluations carried out to assess the environmental impact of a building throughout its entire lifespan
LCAs are widely adopted as good sustainable practice in the construction industry.
What should be reduced to improve energy sources and consumption?
Reliance on fossil fuels and finite resources
Encouraging renewable energy systems is crucial.
What is an important design consideration for water sources and consumption?
Implementing grey water recycling systems and rainwater harvesting systems
These methods help reduce wastage and reliance on water sources.
When selecting materials, what should be considered?
Source and embodied energy values
Sourcing materials locally reduces transportation and CO2 emissions.
What are key considerations when using materials in building design?
- Reducing
- Reusing
- Recycling
- Longevity
- Durability
- Sustainability
These factors impact the building’s lifecycle and environmental performance.
What does flexibility in building design allow for?
Buildings to evolve over time as the needs of the user may change
This may include moveable partitions and multi-use spaces.
What must buildings be durable against?
- Climate change
- Wear and tear from occupants
- External elements such as snow, wind, or rain
Durability ensures long-term functionality.
What should be assessed to minimize pollution and waste processing?
Potential pollution caused by construction activities
Waste management plans are essential for controlling waste production.
What is a key consideration for transport in building projects?
Minimizing the transportation of materials, tools, equipment, and human resources
Sourcing materials locally reduces environmental impact.
What should be considered during the deconstruction and disposal of a building?
Processes involved in demolition and reusing materials whenever possible
Pollution during demolition includes noise and air pollution.
What is Passivhaus?
An energy performance standard originating in Germany aimed mainly at new buildings
Passivhaus can also be applied to refurbishments.
List the properties of Passivhaus buildings.
- High insulation quality
- Heat control
- Robust windows
- Airtight building envelope
- Heat recovery ventilation
- Thermal bridge avoidance
These properties are crucial for maintaining constant temperature.
