Essays on Indoor Air Quality

The term ‘Ergonomic' denotes two phrases of Greek, ‘ergon' that implies work, as well as ‘nomos' that implies laws. Currently, the phrase describes the art of devising a job or activity to fit a labourer and not compelling a labourer to fit a task (Salvendy 274). Ideally, this implies designing a workplace to offer the feasible attainable comfort as well as avoiding work-related injury or stress. Ergonomics encompasses all facets of a task that ranges from some physical stresses work places on nerves, bones, joints, muscles, as well as tendons to environmental issues that impairs vision, hearing, or overall ...

According to Lara (2011), asthma is a lifelong illness that is characterized by aspects involving wheezing, coughing, and irritations. In this instance, the ailment is caused by the inflammation of the bronchi located in an individual’s lungs. Upon inflammation, the airways become blocked and thereby leading to increased difficulty in breathing. Asthma is deadly, owing to the increasing prevalence of the illness among both the adult and children population. Asthma is identified as one of the most chronic illnesses affecting children, approximately 6.3 million individuals (CDC, 2011). In this regards, almost 24% of children ranging from 5 to ...

Section 1. The Problem

Asthma is a chronic airway condition affecting 6.3 million children or 8.6% of the population younger than 18 years (CDC, 2016). School-age children spend 6-7 hours of each day in school for 171-182 days per year (NCES, 2011). As such, the school is a suitable environment for asthma prevention and management. For instance, there are schools which have implemented asthma programs to educate students about asthma and self-management, develop asthma action plans, and create safe environments for learning (CDC, 2015). The chosen setting is a school district in a county in a northcentral U.S. state. It is composed of ...

1.0 Introduction

When the concept of green building emerges, environmentalists and researchers automatically assume the solutions lie on materials and their constituencies in buildings they are part of and the lifetime of the building. Exterior material directly in contact with the environment and natural elements may enhance the sustainability of the building, but may greatly impact the functions of nearby ecosystems. Hence building sustainability and environmental maintenance are not exactly interchangeable, and yet these terms are often utilized mistakenly. The pioneers of environmental constructs are not confirmed, although architectural historians suggest they date back prior to Ancient Roman times. Architects took ...

Introduction

The concept of sustainable development within the industrialized nations and the increased worries caused by global warming, has led to a global interest in the need to come up with better ways in which building construction projects within the urban settings can be done in such a manner as to promote sustainability of our environment as opposed to the rather “business as usual” myopic concept in building projects. This will ensure that this generation meets its own needs without negatively interfering with the ability of the coming generation to meet their own needs. In most scenarios, most building projects can ...

Indoor Air Pollution: Diagnosing the Causatives and Effects

Indoor air pollution is the presence of physical, chemical and biological contaminants in the indoor air that are never present in the quality and environmental friendly atmosphere. These contaminants can be particulates, gases, moulds or radon which is the main causes of the pollution. The human immune system protects the entire body against the negative effects of these contaminants. The contaminants impair the immune system after prolonged exposure. A survey published on the metropolitan area of Toronto revealed that almost 2 percents of the annual deaths were caused by indoor air pollution (Tom, 1996). In this essay, we have ...

Abstract

The number of worldwide issues concerning environmental safety and corporate social responsibility has been on an ever-increasing rate. This is why we can also see a significant growth in the demand for environment-friendly and self-sustaining buildings. The number of domestic and international organizations that monitor and facilitate the standardization by means of a tiered certification of such buildings has also been on an ever-increasing rate. The LEED certification program is one of the most prominent ones in the U.S. and the UC Davis Brewery, Winery, and Food buildings have received platinum grade certification under such program. The objective of this paper ...

I. Introduction In the new millennium, professional builders and clients have recognized the major contribution of buildings to carbon dioxide and other greenhouse gas emissions worldwide. The control of building energy use and GHG emissions represents a major solution to the problem of expanding energy usage. Hence, architectural and design firms, engineering firms, specialized consulting firms, and even small architectural organizations have now turned to green methods in making new buildings. According to Yudelson (p. 3), they have subscribed to the LEED evaluating and rating systems. They lead the sustainable way to construction and design. LEED is a green ...

Introduction

Quality of air is a determinant in the quality of life, indoor air is important as people spend on average 80-90% of their lives in door (WHO, 2007). Indoor air quality began a long time but only been a health concern decades ago when awareness of contaminants presented in the air. The problem begins when the construction of building are highly insulated to conserve energy, which caused a trap to air intoxicants inside the building (E. Willard, 2005). This causes the exchange of outdoor to indoor to lessen and therefore the indoor air pollution builds up.

Indoor air quality is a complex issue as ...
