Thermal insulation is important to regulate temperature. Different types and amounts of insulation provide varying levels of temperature regulation for different climates, from severe to mild. The R-value is a measure of insulation's ability to resist heat flow and the higher the R-value, the better the insulation performs thermally.
Insulation and thermal comfort are important for buildings. Heat flows from warmer to cooler bodies through conduction, convection, and radiation. Insulation works by reducing heat flow through conduction in materials with low conductivity like still air, wood, and fabrics. Insulation products like fiber mats and foam boards contain air spaces that inhibit heat transfer. Proper insulation and limiting heat loss keeps indoor environments comfortable for occupants.
Felt is a non-woven fabric produced by matting, condensing and pressing wool fibers. It has been produced for over 8,000 years using heat, pressure and moisture to cause the fibers to interlock. Wool fibers have scales that allow them to stitch together when rubbed with water and friction. Early felt artifacts have been found in Siberia and it was used by various cultures for clothing, tents, armor and other purposes due to its strength when wet. Traditional Mongolian feltmaking involves layering wool, spreading water on it, and rolling it while applying pressure to fully mat the fibers together.
Active Acoustic Absorption General Presentation Applicationsahmad bassiouny
This document discusses active acoustic absorption using an active impedance control method. It aims to design a broadband acoustic absorber by controlling the resonance frequency and quality factor of an acoustic resonator. This is achieved by modifying the mechanical impedance at the interface using simple electric control. The goals are to match the acoustic impedance to the characteristic impedance of the medium for total absorption, and to increase the absorption bandwidth. Calculations and preliminary experimental results validate the concept of using active materials like electrodynamic loudspeakers to realize active acoustic absorption.
Sound absorption insulation uses materials with numerous holes and fissures to resist sound from reflecting into a room. Acoustical ceiling tiles and panels are the most common type of sound absorption insulation that contains many small holes to trap sound waves.

Architectural acoustics topics and remedies - short presentationJayanshu Gundaniya
This document discusses factors that affect architectural acoustics, including reverberation time, loudness, echo effects, structure-borne sound, focusing of sound waves, and resonance. It explains how each factor impacts sound quality and lists remedies such as using sound absorbing or reflecting materials on walls and ceilings to optimize reverberation time and loudness or prevent echoes and focusing of sound waves. Modeling acoustic effects in a water tank can help design actual halls to avoid unwanted resonance.
This document discusses various causes and types of dampness that can occur in buildings. It describes rising damp, which occurs when water rises up walls through capillary action from the soil. To prevent this, damp-proof courses (DPCs) made of impervious materials like slate or bitumen felt are installed. Deterioration or bridging of the DPC can lead to dampness. Hygroscopic salts in rising damp water can also cause issues by continuing to attract moisture after repairs. The document also discusses penetrating dampness from external water entering walls, condensation dampness caused by high humidity and ventilation issues, and bridging of cavity walls. Treatments include replacing or injecting new DPCs, drainage improvements,

Waterproofing is done to prevent water from penetrating buildings. It involves applying membrane barriers like bitumen or PVC during construction. It can also be done later to address leaks. Common areas waterproofed include bathrooms, terraces, basements, and roofs. Materials used include cement, sand, metal chips, brick bats, and waterproofing chemicals. Techniques include applying cement coats sloped away from the building, with brick bats or tiles in between coats. Thorough preparation and multiple curing coats are important for effective waterproofing.
Climatology is the study of climate elements like temperature, humidity, wind etc and their impact on architecture. Architectural climatology involves studying how climate affects human comfort and designing the built environment accordingly. Key considerations include site planning based on topography, passive solar design, daylighting, ventilation, moisture control and noise control. Design strategies aim to benefit from positive climate elements while mitigating negative impacts through techniques like insulation, absorption, damping, isolation and appropriate material selection.
