This guideline defines ventilation and then natural ventilation. It explores the design requirements for natural ventilation in the context of infection control, describing the basic principles of design, construction, operation and maintenance for an effective natural ventilation system to control infection in health-care settings.
Supplies guidance relevant to facilities for surgical procedures in all healthcare settings. This volume covers the facilities required to support in-patient operating theatres in an acute general hospital.
These guidelines provide recommendations that outline the critical aspects of infection prevention and control. The recommendations were developed using the best available evidence and consensus methods by the Infection Control Steering Committee. They have been prioritised as key areas to prevent and control infection in a healthcare facility. It is recognised that the level of risk may differ according to the different types of facility and therefore some recommendations should be justified by risk assessment. When implementing these recommendations all healthcare facilities need to consider the risk of transmission of infection and implement according to their specific setting and circumstances.
This document is an evidence-based policy for the implementation of sound tuberculosis (TB) infection control by all stakeholders. The evidence base for the policy was established through a systematic literature review. The review highlighted some areas where evidence supports interventions that add value to TB infection control. A number of recommendations were developed, based on this evidence and on additional factors, such as feasibility, programmatic implementation and anticipated cost.
Hazim Awbi's Ventilation of Buildings has become established as the definitive text on the subject. This new, thoroughly revised, edition builds on the basic principles of the original text drawing in the results of considerable new research in the field. A new chapter on natural ventilation is also added and recent developments in ventilation concepts and room air distribution are also considered. The text is intended for the practitioner in the building services industry, the architect, the postgraduate student undertaking courses or research in HVAC, building services engineering, or building environmental engineering, and the undergraduate studying building services as a major subject. Readers are assumed to be familiar with the basic principles of fluid flow and heat transfer and some of the material requires more advanced knowledge of partial differential equations which describe the turbulent flow and heat transfer processes of fluids. The book is both a presentation of the practical issues that are needed for modern ventilation system design and a survey of recent developments in the subject
Health care HVAC systems serve facilities in which the population is uniquely vulnerable and exposed to an elevated risk of health, fire, and safety hazard. These heavily regulated, high-stakes facilities undergo continuous maintenance, verification, inspection, and recertification, typically operate 24/7, and are owner occupied for long life. The HVAC systems in health care facilities must be carefully designed to be installed, operated and maintained in coordination with specialized buildings services, including emergency and normal power, plumbing and medical gas systems, automatic transport, fire protections and a myriad of IT systems, all within a limited building envelope.
This document, with a focus on the built environment and health care facilities, intends to guide the audience in preparing for and responding to SARI pandemics caused by existing and novel pathogens. It provides technical guidance on designing, establishing, and managing health care facilities for severe acute respiratory infections (SARI), covering point of entry, treatment centers, entry to health system facilities, quarantine and community facilities, and home care and quarantine. Organized into three sections, it covers theoretical foundations, design principles, and implementation examples, including solution for new constructions, buildings repurposing, and temporary tent solutions.
