Climate Control May 2019

The construction and renovation of buildings uses precious natural resources These buildings later are responsible for a signifcant proportion of all our carbon emissions Buildings and construction together 2 account for 36% of global final energy use and 39% of energy-related carbon dioxide (CO ) emissions when upstream power generation is included.

Under the Climate Change Act 2008 we have a legally binding target to reduce these emissions by at least 80% by 2050. Providing thermal comfort without excess space conditioning costs is one of the primary requirements of buildings. Therefore, thermal control is an important aspect in almost all buildings. Understanding heat transfer and the temperature distribution through building materials and assemblies is also important for
assessing energy use, thermal comfort, thermal movements, durability, and the potential for moisture problems. The control of heat flow in buildings requires insulation layers compromised with few thermal bridges, an effective air barrier system, good control of solar radiation, and management of interior heat generation.

This edition consists of information on climate control reasons, HVAC growth, HVAC accessories availability and smart cooling system.
