    thought to be around 300-500 lux. Task B Explain the need for ventilation and discuss the relationship between ventilation to a building and heat losses from the building in thermal comfort terms. Ventilation is the process of replacing old stale air in any space to provide a high air quality which in parallel can control temperatures, remove moisture and regain oxygen while also remove unwanted gasses such as odors, smoke, heat, dust, airborne bacteria, and carbon dioxide. Ventilation is used to introduce outside air, to keep interior building air circulating, and to prevent stagnation of the inside air of a building. This all entails both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for sustaining suitable indoor air quality in buildings. There are various methods for ventilating a building. Natural ventilation pushes outdoor air through various openings such as windows, doors, solar chimneys, wind towers and trickle ventilators. This natural ventilation of buildings depends on the weather conditions and the design of the building. Another method of ventilation is mechanical ventilation. Fans can either be installed directly in windows or walls, or installed in air ducts for delivering air into, or eliminating air from a room. The type of mechanical ventilation used is, again, based on the climate. A balance is needed in ventilation as too many openings or excessive air being lost can lead…

  • Passive Cooling Strategies In Natural Ventilation

    1.0 Introduction Natural ventilation is the process of supplying and removing air by means of purpose-provided aperture (such as openable windows, ventilators and shafts) and the natural forces of wind and temperature-difference pressures. In the process, fresh air is introduced and ventilated air is removed from an occupied space. The primary aim is to preserve the qualities of air. (Amit Gupta, 2006). It may also be used to lower the temperature inside an occupied area for thermal comfort. …

  • Arwad Island Case Study Essay

    5.3. Ventilation: No matter the courtyard is small or big in these two buildings, the ventilation still has very small values, due to the closing massive walls towards the outside and opening towards the inside in the origin design, and the semi-closed windows later during the operation. Both buildings need an increase of ventilation ranging between 0.06-0.1 m/s comparing with 0.15 m/s of ANSI/ASHRAE Standard for occupant comfort (ANSI/ASHRAE 1992), taking into account the consideration of…

    cope with these changes, it is necessary to prepare and train healthcare workers to improve employees' knowledge and the quality of care. Limited clinical experience with mechanical ventilation approach, like high frequency oscillatory ventilation (HFOV), makes its implementation difficult in the real critical care world. The authors investigated the effectiveness of technology- enhance simulation with debriefing in improving participants’ confidence level, cognitive knowledge and psychomotor…

  • Essay On Noninvasive Ventilation

    Introduction What is noninvasive ventilation? If you are a person who googles everything, then you will be redirected to the article Noninvasive Ventilation written by Guy Soo Hoo that states “Noninvasive ventilation (NIV) refers to the administration of ventilatory support without using an invasive artificial airway (endotracheal tube or tracheostomy tube).” Now if you are a person that likes to look at books to get the answer, then David W. Chang wrote in Clinical Application of Mechanical…

    Description of current deficit and Issue Requiring Change During the observation for the last few years, it has been concluded that the deficit or lack of knowledge on the transmission of ventilator associated pneumonia (VAP) on critical ill patients in mechanical intubation is the major cause of the increased VAP infections. Pneumonia is an acute inflammation of the lung tissue which can be bacterial or viral. Ways that pneumonia organisms reach the lungs can be due to aspiration of organisms…

  • The Importance Of Respiratory Care

    made in respiratory care, it leaves us with a number of different therapies and equipment available to suit the needs of patients from any age, disease, and demographic. Though these different options are accessible to most acute care hospitals, there is not enough education being done for the proper implementation of these resources or protocols to help drive them. In terms of neonatal non-invasive ventilation, there are several methods of helping ventilate or fix an oxygenation issue to…

  • Abnormal Breathing Patterns Essay

    They all have a similarity, but they are all almost completely different in most ways. Cheyne-Stokes respiration is one of the major challenges in abnormal breathing patterns as stated above the respirations become faster and deeper, after respirations they become slower and shallower and at the end of each respiration a period of apnea will occur. Treatments are effected to help control these type of abnormal breathing patterns. CPAP decreases Cheyne-Stokes respirations by fifty percent…
