Book Description
Various schemes which have been advanced for expressing the significance of a given set of environmental conditions as a single number, or as a semi-quantitative simple phrase, are reviewed. An index of relative strain is developed, similar to that used by Belding and Hatch in their heat stress index, but based on Burton's wet clothes formula for the calculation of actual and relative cooling demands. A chart is developed in which relative strain lines are drawn on a psychrometric chart for standard conditions of activity, clothing, air movement, and radiant heat transfer most likely to be found in shelters. A table is provided for adjusting the reading on the chart for certain non-standard conditions of activity and air movement. The significance of each zone for a standard ''average'' person is expressed in graphic form for such considerations as comfort, discomfort, distress, failure, performance, and tolerance. Further charts indicate the significance of each zone for non- standard states.

Book Description
Observations were made of the thermal environment in the basement portion of a box shaped reinforced concrete 200 person shelter when the shelter was supplied with a minimum quantity of ventilation air. Also, an evaluation was made of the distribution of the ventilation air in the shelter as measured by variations in effective temperature, when the air was supplied through a duct system and through a single point source. Ventilation air conditioned to simulate a 1% design day in the Washington, D.C. area (i.e. air at dry bulb and wet bulb temperatures which will not be exceeded more than 1% of the time), was supplied to the shelter area tested. Approximately 100 simulated occupants were placed in the shelter basement to generate the same amount of heat and moisture as 100 human occupants. When conditioned air was supplied at a minimum rate of 3 cfm per person, effective temperatures as high as 90 deg were attained and maintained within the shelter. Based on current standards for the thermal environment in shelters, it is concluded that a minimum ventilation rate of 3 cfm is not adequate for cooling this shelter space.

Book Description
The shelters are like a housing structures used for the army for sheltering in terrain places. These shelters are mounted over the army vehicles which are subjected to static, dynamic and thermal loads due to vehicle transportation in all kinds of terrains. The shelters are subjected to a different thermal loads due to seasonal externally temperatures and inside there are heat dissipating elements. The objective is to maintain the temperature inside the shelter at around 27 degree centigrade for which the CFD analysis is performed. This study uses the Fluent software to evaluate the indoor thermal environment of Shelter and the analysis is to perform Thermal and air flow studies for prediction of the temperatures when the components are dissipating heat inside the shelter. Shelter contains four Panels and one air pre heater which dissipate heat. The shelter subjected to an extreme operating temperature -30 to +55 centigrade and there is need of AC's for temperature control. In this study the location and number of AC's required and on off conditions are studied using Fluent solver for the temperature predictions.The steady state and transient analysis is performed using Fluent.

Book Description
Thermal stress due to heat or cold may impact comfort, the ability to conduct operations, and, potentially, the survival of Warfighters. This report provides background information and methods for characterizing the properties of enclosed spaces (vehicles, shelters, other enclosures) that impact the thermal state of Warfighters. Quantification of the thermal environment of an enclosure consists of measuring air and surface temperatures, humidity, air flow; and radiant load. Methods focus on obtaining enough data to define each microclimate within the target space. Three studies of concrete tanks and metal containers, the High Mobility Multipurpose Wheeled Vehicle; and the Bradley Fighting Vehicle, are described.

Book Description
This timely book offers a unique interdisciplinary inquiry into the prospects of different political narratives on climate migration. It identifies the essential angles on climate migration – the humanitarian narrative, the migration narrative and the climate change narrative – and assesses their prospects. The author contends that although such arguments will influence global governance, they will not necessarily achieve what advocates hope for. He discusses how the weaknesses of the concept of “climate migration” are likely to be utilized in favour of repressive policies against migration or for the defence of industrial nations against perceived threats from the Third World.

Book Description
Improved housing conditions can save lives, prevent disease, increase quality of life, reduce poverty, and help mitigate climate change. Housing is becoming increasingly important to health in light of urban growth, ageing populations and climate change. The WHO Housing and health guidelines bring together the most recent evidence to provide practical recommendations to reduce the health burden due to unsafe and substandard housing. Based on newly commissioned systematic reviews, the guidelines provide recommendations relevant to inadequate living space (crowding), low and high indoor temperatures, injury hazards in the home, and accessibility of housing for people with functional impairments. In addition, the guidelines identify and summarize existing WHO guidelines and recommendations related to housing, with respect to water quality, air quality, neighbourhood noise, asbestos, lead, tobacco smoke and radon. The guidelines take a comprehensive, intersectoral perspective on the issue of housing and health and highlight co-benefits of interventions addressing several risk factors at the same time. The WHO Housing and health guidelines aim at informing housing policies and regulations at the national, regional and local level and are further relevant in the daily activities of implementing actors who are directly involved in the construction, maintenance and demolition of housing in ways that influence human health and safety. The guidelines therefore emphasize the importance of collaboration between the health and other sectors and joint efforts across all government levels to promote healthy housing. The guidelines' implementation at country-level will in particular contribute to the achievement of the Sustainable Development Goals on health (SDG 3) and sustainable cities (SDG 11). WHO will support Member States in adapting the guidelines to national contexts and priorities to ensure safe and healthy housing for all.
