Materila Failure and Embodied Energy - Essay Example Source: Embodied energy in house construction, Energy Efficiency, 2006 Embodied Energy There are 18 criteria laid out in the Green Book that form the basis of ways to reduce carbon emissions. This book serves an effective control in helping construction companies identify the materials that have a high percentage of embodied energy contained in them. This helps in constructing the buildings with low carbon content hence lower embodied energy. Embodied energy can be defined as the total amount of energy that is required to construct buildings using materials like cement, aluminium and steel. Total energy that is defined in this context means the sum total of all energy that would be required to build the material, transport it to the site and also the energy that would be used in construction purpose. (Lucuik Mark, 2007) To elaborate further a company engaged in construction activities in Kuwait might source these construction bricks from China. Therefore the embodied energy of this b rick would include the energy used in brick construction in China, transportation energy from China to Kuwait and ultimately the energy used to lay the brick and constructing it in Kuwait. It would also involve the additional energy that would be further required to process the bricks at the site to enable it in laying. Thus all the energy that is used in machines engaged in excavation and shoring out raw materials, to the energy that is required by the human personnel in construction of the building at site go into the summation of energy of the product which is defined as its embodied energy.

Sturgis Associ ates use a tool lnown as RICS to gauge the embodied carbon of different types of buildings engaged in operations of different nature like store house, work shop facility and supermarkets. The embodied carbon content of a storage warehouse exists in the range of 60% while a supermarket which is always lit up with snazzy lights to attract customers has an embodied carbon of 20%. A normal household is a mix of these two types of buildings and has an embodied carbon content of 30%. Another factor that defines the calculations used in RICS includes the life cycle or the total life of the building. These may vary from 25 to 80 years. (Lane Thomas, 2010) Therefore apart from the kind of construction, the total life span of the building structure all go into accounting the embodied carbon efficiency of materials. Measuring the carbon footprint of a building is a twofold process. It involves calculating the energy that is required in constructing the building and also adding the embodied ene rgy of the materials that are replaced over a period of time during the building lifecycle. Apart from the RICS there are a number of software’s available in the market capable of predicting the embodied energy of the construction materials used in buildings. Apart from this energy the operating energy that would also go into the

Security Roles CCJS - Essay Example Control is applicable to people, technological devices and information. James (2013) highlights that they ensure access is given only to authorized and people. They ensure control through proper identification and authentication before they authorize entry into premises. It is important to note that controlling access to an organization is a critical step towards ensuring that the assets are secure. It is through unmonitored access that assets are stolen or destroyed on intentional basis. Access protection limits hazards that can lead to loss of property. Related to access control, the security department also takes the responsibility of doing patrols and monitoring the surveillance facility to check for anything unusual that could lead to loss or damage to the assets (Indira, 2009). They are held responsible to detect fraud or misuse of an organization’s assets. A security director heads a security department and usually reports to the Chief Officer. Marian (2011) points that his managerial role involves managing security officers in order to ensure that facilities are well protected. He/she delegates responsibilities to them by developing regulations and procedures that guide their activities. Another role involves assisting and giving advice to the heads of operating units in ensuring that safety is enhanced (Marian, 2011). The director advises departmental heads on strategies and steps to take in ensuring that the facility is managed effectively and assets protected. He/she coordinates information exchange and security services to ensure that assets are protected. It is the role of the director to implement a security program and coordinate all departments to ensure that the policies are followed. The administrative functions of a director revolve around taking part in training officers in matters related to monitoring and protection of assets. The director also directs installation of programs that will support
