1. Indoor Air Quality in the Hospital: The Influence of Heating, Ventilating and Conditioning Systems
Abstract Clean, fresh air is the most important requirement for good indoor air quality (IAQ) in all buildings, but it is especially important with regard to the environments within hospitals and other healthcare facilities. The literature indicates that buildings with heating, ventilating and air conditioning (HVAC) systems may have an increased risk of sic

2. ANALYSIS OF AIR QUALITY IN SELECTED AREAS OF A POULTRY PROCESSING PLANT WITH THE USE OF A MICROBIOLOGICAL AIR SAMPLER
ABSTRACT The aim of the study was to analyze the air quality in selected production facilities specified as the so-called "high-risk zones". Air samples were analyzed using either the sedimentation or the impaction methods. The impaction method showed the applicability of the air sampler in in-situ measurements. An increase in the numbers of aerobic bacteria

3. Calidad del aire en galpón avícola con ventilación natural durante la fase de pollitos
ABSTRACT Broilers during the first phase should be protected from cold stress, especially in the winter, cold nights and early mornings. To protect animals, poultry producers have used different strategies, including the use of multilayer of curtain, to increase the thermal insulation and reduce heat losses, also decreasing the permeability to the external a

4. Numerical study of the influence of internal heat source in naturally ventilated offices
Abstract The natural ventilation in a building performs a fundamental role in users' welfare and health, when used as a bioclimatic and architectural strategy, it can provide brighter projects. Increasing the indoor air speed ventilation has an important performance maintaining indoor air quality, contributing to thermal interactions between human body and e

5. Integración de criterios de desempeños en el mejoramiento energético-ambiental de viviendas sociales existentes en Chile
In Chile, 75% of the existing housing stock was built without energy-environmental considerations. These houses are becoming high energy consumers in the country. Nowadays, it exist different measures to improve the energy efficiency of existing dwellings, but these benchmarks consider only some performance that have implication on the energy demand. Normall
