AbstractPrinciples of Building Acoustics, Water and Fire safety
ObjectiveBuilding Acoustics
- Fundamentals of sound: Sound waves, Sound sources and free field sound propagation, Sound descriptors and sound levels
- Sound fields in rooms: Reflection and absorption at boundaries, Diffuse sound fields (reverberation time), Room modes
- Airborne sound transmission through building elements I: Homogenous structures: Monolithic elements, Double leaf elements (walls, windows, ), Linings, toppings and additional layers
- Airborne sound transmission through building elements II: Assembled (lightweight) structures: Double leaf framed elements
- Impact sound transmission through building elements: Impact sources, Floor elements and floor toppings, Introduction structure-borne sound and vibration
- Sound transmission in buildings I: Composite elements, Flanking sound transmission I: Concept of flanking, Monolithic buildings
- Sound transmission in buildings II: Flanking sound transmission II: Lightweight framed buildings, Outline prediction methods, Noise from building systems and installations
- Measurement, Descriptors and Regulations: Standardized measurement techniques and protocols

Water
- water supply: water needs, possible resources, quality requirements for different applications and possible treatment processes
- water distribution: requirements for storage and piping
- wastewater: different type: urine, feces, blackwater, light and heavy greywater, rain water, treatment possibilities, hygienic and comfort requirements
- water cycles
- wastewater as a resource: polishing water, nutrients, energy
- integral solutions off the grid
- water as part of the urban environment and for recreational purposes in cities
- examples

Fire and Safety
- Fire safety objectives and regulations
- Fire safety concepts and measures
- Fire statistics
- Human behavior and escape
- Structural fire safety
- Technical fire safety
- Organizational fire safety
