Optimizing solar thermal resurce Essay Example | Topics and Well Written Essays - 500 words

Optimizing solar thermal resurce - Essay Example Such cities includes; Oakland 17%, San Franscisco 12% and Porland 10% (Ten top cities in U.S.A for renewable energy) . In his paper (Cleveland) explains how solar energy can be optimized. This paper represents a method of analyzing the financial costs and benefits of solar systems in commercial buildings using a model building. Assumption made are; the house is 30% below ASHRAE 90.1 standards, the owner is interested in investing on thermal technology and wanted to build the most efficient building possible, consideration of natural gases and electricity escalations as alternatives to solar energy. The model house was 50,000 sq feet and cost of building such a house in Calorina is $500,000 to 750,000 with fully installed HVAC system. Energy plus was used to map the building. The inputs for the energy plus simulation included, Raleigh, NC location, u-shaped office building of 50,000 sq ,30% energy savings among others and this led to projection output of heating system capacity 641 kBtu/hr (includes hot water usage), 87 tons of cooling capacity required, annual HVAC electricity use and annual natural gas use, hot water cooling. The model house was used to run 2 cooling scenarios one with traditional HVAC as control building and the other one with traditional cooling system and solar heating and cooling system (solar building).The sizing of thermal loads of absorption chiller was based on information sourced from energy plus and this ensured that it had that same output as HVAC system. The amount of solar thermal energy supplied to heating water, heating space and cooling the space was calculated using RET screen which is able to estimate energy production, savings ,cost, viability and risks of various renewable energy and energy efficient techniques. In order to determine the comparative value of solar heating and cooling system and traditional HVAC system, net present value (NPV) of each system

Response to Intercultural Outgroup Members Essay

Response to Intercultural Outgroup Members - Essay Example What makes these black guys scary is only in her eyes, but because these guys were aggrieved, they made her fear come true, they pulls out a gun, points on theirs face and carjacked them. This results biased judgment for blacks. Jean holds prejudice against people on the basis of skin color and cultural race. She discriminates the Mexican-American locksmith because he looks like a "gang member," with a shaved head and tattoos, when actually he is a devoted family man. She thinks that the locksmith would sell their keys with his allegedly gang banger friends. But the offended locksmith proved her dilemma to be wrong. Another racist, Officer Ryan (Matt Dillon) is a white police officer who molests Christine, a black woman, during a traffic stop. Meanwhile, Ryan is trying to get help from Shaniqua Johnson, a black woman, for his father, who may possibly have prostate cancer but seems to have been misdiagnosed with a bladder infection, Urinary Tract Infection (UTI). Ryan's racist remarks to a black insurance representative (Miss Johnson) prevent him from getting his father the treatment he needs. His racial prejudices seem to stem in part from the negative impact that local affirmative action-style policies that favored minority businesses had on his father's business, family, and life. Ryan later relieves the viewers of his racist tendencies when he saves Christine from certain death in a fiery car wreck and is seen working with a Mexican-American Patrolman whom he seems to show no signs of prejudice towards.

So here enters Officer Hanson who is having an embarrassing problem, for personal nature. He is Officer Ryan's partner, who is disgusted by Ryan's racism and the city's inaction. After trying to get another partner after seeing Ryan molest Christine, Hanson accepts a solo patrol vehicle. Hanson saves Cameron during his confrontation with the police, yet shoots Peter when Peter reaches for what he suspected was a weapon, but was actually a statuette of Saint Christopher in his car after picking him up and giving him a ride. He dumps the body and burns his car in an attempt to hide evidence. Another issue raised in this chapter is - if the ingroup does not approve of an individual's behavior, it can reject the ingroup member. This was manifested when a black guy (Anthony) tries to carjack his black fellow, Cameron. Thus Cameron felt embarrassed because of Anthony's wrong doing.
