Sampling and identifying of mould in the library building
Despite the growing concern over mould and fungi infestations on library building, little has been reported in the literature on the development of an objective tool and criteria for measuring and characterising the mould and fungi. In this paper, an objective based approach to mould and fungi growth assessment using various sampling techniques and its identification using microscopic observation are proposed. This study involved three library buildings of Higher Institution Educational in Malaysia for data collection purpose and study of mould growth. The
mould sampling of three libraries was collected using Coriolis air sampler, settling plate air sampling using Malt Extract Agar (MEA), IAQ MOLD Alexeter IAQ-Pro Asp/Pen® Test and swab sampling techniques. The IAQ MOLD
Alexeter IAQ-Pro Asp/Pen® Test and traditional method technique identified various mould species immediately on
the site, and the microscopic observation identifies common types of the mould such as Aspergillus, Penicillium and Stachybotrys's. The sample size and particular characteristics of each library will result in the mould growth pattern and finding
Effect of landscape density in a residential area on thermal performance in a tropical climate
It is a well-documented that the urban air temperature is gradually growing in all cities due to the rapid development of buildings, roads and other infrastructure, human activities and also decreasing in vegetated areas. In a tropical climate, outdoor environment is clearly warmer than indoor environment due to higher air temperatures, particularly in dry seasons. Since the indoor environment is influenced by its surroundings, this situation indirectly contributes to the discomfort indoor environment in the building. Thus, it generates to the dependence on mechanical ventilation and increase the energy consumption in buildings. Many research studies have proof that plants not only beauty a city, but also improve the urban environmental condition by reducing the transferring of heat flux on buildings and increasing the reflection of radiation and shading. Therefore strategically placed vegetation around a building could decrease the energy consumption in buildings by reducing the adverse impact of some climate elements. Overall, this paper focuses on the results of a preliminary pilot study of two Semi-Detached houses with different landscape density in Seri Iskandar, Perak. Three climatic parameters, building configuration, and landscape design measured and analyze in this paper

A field study of mould growth for Institute Higher Education library buildings in Malaysia
This paper is part of a PhD field study that focuses on the importance of conducting a visual inspection and evaluation of the indoor climates in libraries. Libraries contain a large amount of stored books that require a stable relative humidity to guarantee its preservation. Mould can survive and grow when indoor relative humidity is high and fungus is present all the time in the air that we breathe. Recording data through visual inspection and field studies. Its recorded the indoor relative humidity, temperature and lighting to assess mould growth problems. The assessment technique for this paper is based on guidelines survey and literature review. Visual inspection found few symptoms of mould growth that related to the amount of moisture appeared when the relative humidity in the library increases. Finally, the recording data for temperature and relative humidity demonstrate the result show that the stable indoor climate in the library building.</jats:p

Analysis of mould growth contamination in library building
The purpose of this paper is to analyse the mould growth and yeast contamination in libraries building. The mould growth causes identified during an investigation and visual inspection of Library PTAR building. The mould contamination level had been measured using 3M Petrifilm Rapid Yeast and Mould Count Plate. The objective of the measurement is to detect environmental concentration for indoor library environment using swab contact monitoring procedures and air sampling procedures. The result recorded yeasts and moulds colonies on the 3M Petrifilm with variably pigmented colonies with certain characters. The yeasts colonies recorded are small, tan colonies with defined edges and no foci while the mould colonies are with diffuse edges and centre foci. They are large, crowd, sporulate and overlap each other on the plate. The result confirmed high contamination count using swab contact, and low contamination recorded using air sampling procedure
