Air permeance of building materials.

             

Passive control of relative humidity to +/- 5%.

Providing Quality for People has many aspects. Of these, one is providing buildings that give clients and users better value for their money. Another addresses the issues of preserving our heritage upon which our quality of life based. This paper describes how these can be achieved using the application of innovative design concepts supported by advanced analytical techniques. For the majority of archive repositories, storing as they do paper type material, environmental conditions of 60±5% and 15.5±2.5 °C are recommended by British Standard 5454.

Evaporation controlled emission in ventilated rooms.

Emission of volatile organic compounds (VOCs) from materials is traditionally determined from tests carried out in small-scale test chambers. Howeyer, a difference in scale may lead to a difference in the measured emission rate in a small-scale test chamber and the actual emission rate in a full-scale ventilated room when the emission is fully or partly evaporation controlled.

Material odour emission test methods: review and evaluation.

This materials odour emission project was conducted for the Task Force on Materials Emissions and four industry sponsors. The objectives of the project were to review material odour test methods, conduct comparative tests of various materials by the most applicable methods and to recommend test methods for materials odour emission characterization. The review identified six test methods which were then compared in a program of odour testing of 1 0 materials. Two test methods were quantitative odour intensity methods and four methods used perceived intensity and hedonic scales.

The influence of area-specific ventilation rate on the emissions from construction products.

Experiments were performed using small-scale climate chambers, including the new Chamber for Laboratory Investigations of Materials Pollution and Air Quality (CLIMPAQ), to gain knowledge about the influence of ventilation rate per plane specimen area (specific ventilation rate) on emission rates. Emissions from pieces of linoleum, waterborne acrylic paint, nylon carpet, and sealant were quantified at different specific ventilation rates.

Thermal comfort simulations for different structured naturally ventilated room.

The objective of this research was to investigate thermal comfort with respect to the mass of the building inside a test room which is naturally ventilated. The room is an existing portable cabin of light mass, located at Loughborough University. The comfort parameters for different mass of the cabin were predicted. For this purpose a simulation package, is used to calculate the thermal parameters defined by Fanger. Medium and high thermal masses were added to the test room and their effects on thermal comfort were investigated.
