materials specification Flashcards
What are the sources of recoverable material?
Storm water collection, timber from sustainable source, grey water harvesting, organic paint, green register of specifications of products
These sources contribute to sustainable building practices.
What percentage of recyclable yarn is used in carpets mentioned?
80%
This highlights the importance of using recyclable materials in construction.
What are the internal finishes listed in the text?
- Internal office walls
- Toilets and showers
- Main access feature staircase
- Main office entrance areas
- Suspended ceilings
- Passenger lift
- Internal columns
- Internal doors
- Cleaners’ stores
These finishes are essential for the functional and aesthetic quality of the building.
What is embodied energy?
The sum of energy required to extract, harvest, process, manufacture, transport, construct, maintain, recycle/dispose
Understanding embodied energy is crucial for evaluating the environmental impact of materials.
What are the key considerations when analyzing a material’s embodied energy?
- Recyclability
- Embodied energy life
- Cycle assessment
- Procurement (sustainable sources and transport)
These considerations help in making environmentally conscious material choices.
What is the benefit of careful analysis and selection of materials?
Significant improvements in comfort, cost effectiveness, and energy efficiency of a building
This can lead to better overall building performance.
What does BRE’s ‘green guide to specification’ provide?
A quick and easy way to assess the environmental performance of 250 construction specifications and materials
This guide aids in selecting environmentally friendly materials.
What are the advantages of green roofs?
- Moderation of internal temperature
- High degree of insulation
- Visual amenity
- Creation of habitat and biodiversity
- Economic considerations
- Control of surface water runoff
These advantages contribute to sustainable urban development.
What is the oldest form of ventilation and cooling?
Natural ventilation
This method has both environmental and financial benefits.
What does a ventilation design strategy consider?
- Single or double opening
- Controls internal heat sources
- Effective solar control using window proportion, design, and shading
- Increased thermal mass and exposed structures
These strategies enhance energy efficiency and comfort.
What percentage of heat loss in an example office building is attributed to building fabric?
Two thirds
This emphasizes the importance of improving building fabric for energy conservation.
What are the reasons for improving building fabric?
- Better temperature control
- More economic use of power
- Improved productivity and occupant comfort
- Lower capital expenditure
- Increased investment potential
- Compliance with building and energy performance directives
These improvements are crucial for sustainable building practices.
What considerations are required by the new Part L?
- Thermal characteristics
- Heating and hot water supply, including insulation methods
- Air conditioning insulation
- Ventilation (natural and fan-assisted)
- Position and orientation of the building
- Passive solar systems and solar protection
- Active solar systems and renewable energy performance
These considerations are essential for compliance with energy efficiency standards.
