Energy Efficient Housing essays

Energy Efficient Housing essays Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers. A smaller airspace doesnt insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window to no longer insulate the building. The air in between the layers of glass should be thick and dense, so that it can save energy. One of the most common airs used in-between glass is argon. When argon is used heat loss is reduced. You could also use carbon dioxide or sulfur hexa-fluoride between glass. Another type of window that is used commonly to keep the home cool is tinted glass. Tinted glass and tinted window films are used on buildings to reduce heat gain through windows. Advancements in tinted glass have now allowed us to make the glass appear just as a regular window that you can see through. The tinted glass solution is also used in many vehicles and private rooms for privacy and to keep them cool in the summer to save on energy costs. When choosing a proper type of window frame, fiber glass is the number one choice. Fiberglass is the strongest material to use for the job and it also involves a smaller amount of maintenance compared to vinyl or wood. Glazes on windows are one of the newest methods for energy efficient windows. Glazing is a way of changed the glass so that the light reflects off the window or absorbs the light and brings it into the building. Photo-chromic is the best product for glazing, as it can be switched so that it both reflects the light and absorbs it. Photo-chromic is a product called a switchable glazing. All switchable glazing products are useful for reducing cooling loads and for minimizing the shine off the sun from coming i...

Challenging Behavior. Causes and Approaches to Dealing with Essay

Challenging Behavior. Causes and Approaches to Dealing with Challenging Behavior - Essay Example There have been claims that challenging behavior is responsible for exposing the tough in an advanced group level which have the effects of resulting into maturity or segregation from the learning category (Similarly, Simmons & Ward 1998).There were also establishments that there are some behaviors that can never be classified easily by the educators such as distractions, chatting as well as the non verbal maltreatments. Nonetheless, there is a different suggestion from Oliver (2003) that, the categorization of behavior appears as challenging throughout diverse schools. According to this scholar, the challenging behavior is developed socially. There is need for evaluating the matter of challenging behavior amongst individuals since it has attracted different theories and approaches from scholars. Therefore, this piece will look at the dissimilar theories that expound on behavior. Specifically, the piece will attain its baseline points of arguments the works by Bandura, Skinner, Vygot sky, and Watson. The piece will evaluate the Cognitive Behaviorist theory and Social Learning Theory. It is also significant to show how each theory takes care of the needs of the child and this paper will respond to that concern. Reasoning from the behaviorist context, there is a realization that behavior could be learned or modified (Skinner 1904-90), the writer affirms this stipulation through the work entitled, ‘Operant Conditioning’. The scholar proceeded into highlighting that children operate on the environment through engagement in particular identifiable activities due to the results of such behaviors. Skinner outlines that any stimulus leading to the repeat of a particular behavior emphasizes that particular behavior. The response would vary from return, reward, attentiveness as well as social assistance. The situation instance to elaborate this suggestion would follow for instance, if a particular child, let us name him Tim confesses to another that he gets pleasure playing with the other named Carol of late. If Tim invites his playmate for dinner in addition, this would invoke the application of the Skinner’s suggestions. It can be proposed that support in the construction of th e scenario would be a smile in spite of the situation, a word of praise for an outstanding behavior. Skinner upheld that particular rewards for such behavior reoccurrence on a different instance or instances. Even though support contributes to the increment in frequency of the behavior, it does it in a dissimilar manner. This situation may arise in the instance when we prefaer promoting a behavior in the child contrary to demanding the behavior in that person. In case something is happening and the child request the parent to stop it in a polite manner and it is done, then the alternate behavior is reinforced. For instance, the child requests for changing of a video clip. If the parent execute the child’s desire then the parent is strengthening the aimed behavior, that of requesting in a polite way. It can be argued that both positive and unhelpful support, when used appropriately can enhance the frequency of the ideal behavior. Major values of conventional habituation were c ontoured by the work of Ivan Pavlov (1819 -1936) where an unbiased stimulus brings about a response if put together with a stimulus that already has that response. Rewarding a student for positive a behavior exhibited enhances that behavior. For instance, if a teacher
