This brochure educates readers about environmental asthma triggers, and highlights the importance of controlling them in order to avoid provoking asthma episodes. It describes five asthma triggers, and suggests simple measures to help curb their presence in the home. The brochure is suitable for a broad audience, with a particular emphasis on parents and care givers of asthmatics. This is an educational tool to help parents and children learn more about asthma triggers. Developed in Spanish, this educational family story chronicles with amazing illustrations and a catchy storyline the antics of the devious FantASMA del asma asthma phantom and the adverse respiratory effects it has on a young asthmatic boy named Vin. The FantASMA literally symbolizes the asthma triggers that can be found in the home to which the Torres family has recently moved. The phantom magically proceeds to transform himself into several different asthma triggers, causing the boy to become sick.

Engineers are always looking for a software that will help them with the designing process and make it easier. The Society and its members focus on building systems, energy efficiency, indoor air quality, refrigeration and sustainability within the industry. The goal of 'Whole Building' Design is to create a successful high-performance building by applying an integrated design and team approach to the project during the planning and programming phases. When this refrigerant is compressed, it becomes quite cold. All rights reserved.

Exposure to indoor contaminants represents one of the most wide-spread exposures affecting public employees. Contaminants generated indoors can be concentrated in indoor air by inadequate or improperly operating ventilation systems that do not provide enough dilution ventilation. Health effects caused poor indoor air quality can range from general malaise, such as fatigue and headache to more serious symptoms such as asthma and infections.

Metrics details. We examined the indoor air quality IAQ perceptions of workers and their relationships with the symptoms of sick-building syndrome SBS and store types in underground shopping centers. In , store workers in nine underground shopping centers in Seoul, Korea, were assessed. Using questionnaires, they were asked about their demographics, job characteristics, 16 SBS symptoms, and seven IAQ perceptions.

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 sick building syndrome SBS and building-related illness BRI if they are not well maintained. Microorganisms are brought into hospitals by people, air currents, water, construction materials and equipment. The main objective of this study was to assess the degree of fungal and bacterial contamination in the University Clinical Centre in Banja Luka, which is directly connected to the HVAC system. Airborne bacteria and fungi in the indoor hospital environment were assessed experimentally. Air samples were collected during the winter season.

This guidance provides information on factors affecting indoor air quality; describes how to develop an IAQ profile of building conditions and create an IAQ management plan; describes investigative strategies to identify causes of IAQ problems; and provides criteria for assessing alternative mitigation strategies, determining whether a problem has been resolved, and deciding whether to consult outside technical specialists. Other topics included in the guide are key problem causing factors; air quality sampling; heating, ventilation, and air conditioning systems; moisture problems; and additional sources of information.

Between attending classes, working a part-time job, going to the gym, finding time to socialize, and remembering about that weekly quiz an hour before lecture, the inevitable exhaustive and delusional feelings students often experience begin to set in before there is time for an afternoon nap. But that sluggish, unfocused feeling does not always reflect their sleep, dietary or even exercise patterns. Rather, it could be the result of poor indoor air quality IAQ found in many buildings on campus, places where students, in addition to faculty and staff, spend much of their day. For each breath humans take, between 1 and 2 million particles are deposited on the inside of the lungs R. Peltier, personal communication, January 20, , and while the majority of those particles are relatively harmless, poor IAQ increases exposure to and likelihood of sicknesses.

Indoor air quality

The spread of Coronavirus is causing in the society all around the world a considerable degree of fear, worry and concern and particularly among healthcare workers that are at increased risk for infection. The role of infection control in the design of hospitals is increasing every day. This paper highlights the role of heating, ventilating and air-conditioning minimizing the risk of infection from airborne transmission within the built environment through the application of best practices.

This paper presents results of over 34, survey responses to air quality and thermal comfort questions in buildings in US, Canada, and Finland. With respect to thermal comfort and air quality performance goals set out by standards, most buildings appear to be falling far short. Occupant surveys offer a means to systematically measure this performance, and also to provide diagnostic information for building designers and operators. Skip to main content.
