An Examination Of The Different Cladding Systems For High Rise Office Buildings In The Modern Era.

The Nature of the Problem to be Solved

Over the years, other cladding systems for high rise office buildings have emerged in the modern era. There has been a high rise in these buildings’ construction, with developing economies characterized by them. It has been caused by a growing economic power that attracts both local and foreign investors. Most commercial buildings have come up with complex structures being the primary factors behind the attractive image components generated by innovations and architecture (Todd & Ramuta, 2014). With this, several cladding systems have sought to enhance the nature of designing the high rise office buildings. Cladding systems play the role of determining how the outer cover of the building appears on the exterior. With a lot of construction design being formulated today, architectures must choose one suitable system when building office buildings in major cities.

This calls for the need to be specific on the details one settles for when looking out for the material that suits the construction work. Some of the things one needs to consider are factors such as building under construction, requirements of insulation, and the type of material to be applied for the cladding product. More than one layer is usually used by the cladding system, which is meant to protect the building structure from being ruined by moisture. Therefore, building contractors must carefully choose a plan that suits their options, which becomes a challenge to them. In most cases, selecting the right type of cladding system is an issue that requires them to first familiarize themselves with the pros and cons of the available options. It makes it easier for them to select the right material to use in the construction.

One of the common types of cladding systems is the use of metal, which is an option that is considered long-lasting and having little maintenance. Buildings embrace it due to its shiny and smooth surface that makes it easy to clean. As a result of this, the metals that are highly used are steel and aluminum, which is usually created by using a variety of patterns and looks. Another option is the use of brick cladding, which tends to be lightweight. It is easy to install, has less maintenance, and it has good insulation. The existence of vinyl cladding is a method that has no care, which is usually suitable for all types of buildings. It is advantageous due to its affordability and its existence in different colors (Todd & Ramuta, 2014). Stone cladding also exists, which is expensive due to the kind of labor required for installation. Wong and Baldwin (2016) explain that timber cladding exists in shingles and planks from different trees, with the option being considered environment friendly.

Most office buildings go for a concrete cladding system because of its ability to support strong structures. But as a result of the wide range of options that exist in the market, change in trends and technology has made it a problem in deciding what options are suitable for the buildings. Large cities are in high demand for high-rise construction, and with the high cost of land, landowners demand that maximum support is given in making the areas useful. One way to make these cities beautiful is by using cladding systems, which should be well chosen to minimize cases where they will be outdated. It calls for the need to come up with modern tastes in architecture by using innovative ideas that have been created by manufacturing companies that suit the condition of the architectural bureaus.

A Project Plan for the Solution of the Problem

The project will entail creating a solution to the problem by seeking a historical evaluation of high-rise construction and using it for positive associations. The initial step will entail understanding large corporations’ desire and what the authorities think about their engagement in embracing technology in architecture. It will be significant in exploring what role the cladding systems have on both the business community and the local administration. A translation should then be done on the project where well-known architectural bureaus will be assessed and company-producers who engage in high-rise construction in modern cities. This step will help in understanding what causes conflicts on architectural dominants, especially those that do not exist in compaunderstande high-rise architectural projects (Todd & Ramuta, 2014). There are cases where a country’s national economy can become overheated; here, the project will analyze how it impacts cladding systems’ types to use.

Therefore, this project plan will involve taking account of the amount of work that has been carried out from the historical period up to date. Acquiring this data is a way of gathering all the information required to determine what can be done to ensure that building constructors develop the best decisions when settling for a cladding system to use during the modern era. Similarly, an account of some of the difficulties that have been faced during the historical times will be identified. The project will assess them and determine ways in which they were overcome. It will apply in the report to help examine the development of the systems and what trends have come up to dominate the market today. The project will then be finalized by a summary of the wok yet to be done in ensuring that building constructors make the best decision when settling for a cladding system as an option for a high-rise building in the modern era.

An Account of the Work carried out to date.

Several factors have played a role in defining historical features that exist within the high-rise buildings. For instance, between the years 2000 to 2010, the height of erected buildings across cities rose, with most offices embracing them. The buildings range from 35 to 100 meters, with some going even above the estimate. It has been caused by several driving factors that have made the changes witnessed in the present time, where we see architectural bureaus come with ideas that seek to make the buildings even more beautiful. One way to enhance their appearances has been through the use of cladding systems, which have existed in the market since the dark ages. An example is the existence of timber cladding, which was used from 500 to 1500AD. The use of wood to make the exterior finishing was common, particularly in Europe and regions dominated by forests.

Cladding systems went further to change in the 16th and 18th century where weatherboards were made, an improved version of wood use. It became common as the building industries combined timber with technology, which made it suitable for construction. Nevertheless, these changes in the 19th and 21st centuries were due to the upcoming trend and technology in the construction industry; there came a higher demand for taller and buildings requiring exterior walls (Momčilović-Petronijević et al., 2018). Therefore, the cladding system became common as modernism was embraced, replacing the use of timber cladding. Methods such as brick cladding were enhanced, which was considered significant as well by the industry. The revolution has still been ongoing, with the modern-day witnessing substantial changes in the cladding systems that have been developed today. A variety of materials are today used for cladding, such as vinyl, metal, and composite materials that have been incorporated to enhance the durability and appearance of the high rise buildings.

An Account of the Difficulties Encountered and How they were Overcome

Some of the difficulties encountered in selecting the cladding systems are the changing trends that require manufacturing companies to keep up with the competition. The cost required to keep up with the change in systems needing close monitoring is done to evaluate what system suits the office buildings well. One of the significant hurdles in developing these systems has been the need to protect the environment when constructing the building. Architectural bureaus recommend that environmentally friendly energy sources should be used when choosing the type of cladding system to use in buildings. The most recommended systems are those that embrace the use of natural products such as wood due to their environmental friendliness. The maintenance cost of the methods is also a challenge with the change in trends as the constructors are forced to keep up with the changes in the market.

As a way of overcoming the challenges caused by trends, architects embrace the use of social media to explore the current designs. During the past years, buildings’ structures were gathered from observation methods and ideas that were initially being collected from peers. But the use of social media is one reliable strategy, given that the internet creates a platform where architects connect and share inspiring designs. It is excellent for collaboration and learning as greater understanding is boosted by the architects sharing the methods and getting to embrace new ideas in the market. It makes the process of choosing an option to use within the high-rise office building even more efficiently. To keep up with the costs associated with the new trends, architects have developed ways of expanding their innovation, creating awards that target projects. As a result of these, architects get a chance to get investors who fund their activities, and through these awards, they get inspiration on what methods to choose for the construction.

An Account of the Work yet to do

With an increasing rate of trends that calls for architects’ need to be informed of what cladding systems suit their construction, there is still a lot that needs to be done. The authorities involved in the building’s construction should initiate policies that encourage the architects to come up with multiple functions that can be used in developing the system designs. This will make it easier for architects to use methods they think are suitable for designing high-rise buildings. The local community can also be encouraged to consider investing in high-rise construction as one way of boosting the innovation process. Constructive feature matter in the buildings, which in this case, to maintain a modern appearance and reduce the scope of work within facilities, issues such as the economic feasibility and interrelation of systems during the building’s construction should be analyzed to help create a positive image for cities. Having the right impression requires technology and having support from both the authorities and the local community will act to market the regions by making the cities attractive.

Bio

The first step in the project is finding a dataset you would like to explore. This project will require you to take a dataset(s) and analyze them using the tools you get in class. You will be expected to graph your data and analyze it using inferential statistics (i.e. T-Tests, ANOVAs, Correlations, Etc). You are not expected to do all these analyses, but you will need to demonstrate an understanding of why the analyses you pick should be used and how to interpret the results.

FIRST STEP: Find some data. I want your data to be on a topic that interests you. I have put some sources of data in the folder below. It may take a while to find data that works for you. This is not an easy task. The data sets need at least 30 cases, with 4 variables in 3 groups. For example: Obtain data from 3 lakes for pH, DO, N, P over 30 sampling events. Because there is a difference between health data and environmental data, there can be some variation. For example:  Lead poisoning rates over 30 years in 5 different age groups based on location/social economic level/etc.

  • Other examples
    • Compare air quality over 3 cities over 30 years for 4 different pollutants.
    • Analyze data from three health studies comparing different cold medicines for recovery time and symptoms.
    • Analyze the demographic change of cities/states/nations for different variables (age, race, economic level, education level)

In the end you will deliver a paper with:

Introduction – Background of the data and why this data needs to be analyzed.

Methods – how you found your data, why you picked this data, analyses chosen.

Results – analysis, graphs, etc.

Discussion/conclusion – why your analysis may have given your the results it did, what further analysis you need.

References – I expect you to hit the literature and write a comprehensive introduction and conclusion with supporting peer-review scientific materials.

Data Analysis: Hypothesis Testing

Use the Sun Coast Remediation data set to conduct a correlation analysis, simple regression analysis, and multiple regression analysis using the correlation tab, simple regression tab, and multiple regression tab respectively. The statistical output tables should be cut and pasted from Excel directly into the final project document. For the regression hypotheses, display and discuss the predictive regression equations.

Correlation: Hypothesis Testing

Restate the hypotheses:

Example:

Ho1: There is no statistically significant relationship between height and weight.

Ha1: There is a statistically significant relationship between height and weight.

Enter data output results from Excel Toolpak here.

http://www.cengage.com/resource_uploads/static_resources/0495096385/12029/image006e.jpg

Interpret and explain the correlation analysis results below the Excel output. Your explanation should include: r, r2, alpha level, p value, and rejection or acceptance of the null hypothesis and alternative hypothesis.

Example:

The Pearson correlation coefficient of = .600 indicates a moderately strong positive correlation. This equates to an r2 of .36, explaining 36% of the variance between the variables.

Using an alpha of .05, the results indicate a p value of .023 < .05. Therefore, the null hypothesis is rejected, and the alternative hypothesis is accepted that there is a statistically significant relationship between height and weight.

Note: Excel data analysis Toolpak does not automatically calculate the p value when using the correlation function. As a workaround, the data should also be run using the regression function. The Multiple R is identical to the Pearson r in simple regression, R Square is shown, and the p value is generated. Be sure to show your results using both the correlation function and simple regression function.

Simple Regression: Hypothesis Testing

Restate the hypotheses:

P.225.6

Topic: “Not in My Backyard” and Environmental Justice — Your Specific Geographic Area

In the last unit, you discussed natural resources and how important it is to manage them wisely and in a sustainable manner. Many countries have implemented regulations to protect these resources and the environment. This can often involve huge investments in infrastructure such as wastewater treatment facilities. Communities face a number of challenges such as what to do with wastes, how to provide energy to citizens and businesses, and how to regulate industries that might pollute the environment. This is often done on a limited budget and politicians are under a lot of pressure to please a lot of different interest groups as they create the policies and make these decisions.

How does a community decide where to locate a facility such as a wastewater treatment plant or a new factory that could potentially bring many jobs into an area? Consider all of the factories and industrial processes that are needed to support a modern lifestyle. The wastes generated have to go somewhere. Often, people can agree that a new power plant, an oil refinery, or waste disposal site is needed. People have a much harder time agreeing where these facilities should be located within their communities. A common phrase used to describe these phenomena is “not in my backyard” or NIMBY.

Because no one wants to live near certain types of facilities, they traditionally have been concentrated in communities where people have the least influence, power, and/or money to prevent their construction. Once constructed, if these facilities negatively impact public health, the environment, and/or the quality of life, the surrounding communities have fewer resources to monitor the effects and/or demand reparation. Many people are now fighting for what is termed “environmental justice” to ensure that the burdens of dealing with pollution are handled in a manner that is fair to all citizens. For additional background on environmental justice, visit this site:

Environmental Justice: EPA. Retrieved from http://www.epa.gov/environmentaljustice/

In 1994, former president Bill Clinton launched a presidential order to address environmental justice in minority and low-income populations. For further information on the presidential order, visit:

Executive Order 12898. (1994, February 11). Federal Register, 59(32). Retrieved from http://www.archives.gov/federal-register/executive-orders/pdf/12898.pdf

Although environmental regulations are set in place, it is often difficult to ensure that those regulations are being followed or enforced. Citizens should be aware of pollutants that might be in their communities. To learn more about what is in your area, you can start looking here:

Superfund Sites Where You Live: EPA. Retrieved from http://www.epa.gov/superfund/sites/

The idea of NIMBY is not limited to one community or country. Rich and powerful countries often impose restrictions and regulate industries and other polluting operations. Complying with environmental regulations can be very costly, so many corporations have moved facilities to countries that either has less stringent environmental practices and/or have fewer resources in place to enforce environmental policies.

This week, please answer the following questions for Discussion:

  1. What facilities (current or historical) might be responsible for the release of pollutants into your community?
  2. Are they spread throughout your community or located in one area?
  3. If you were in charge of setting policies, how would you ensure that the burden of pollution was shared equally or fairly amongst all citizens?
  4. Do some research on your own to find information about a conflict either between communities within the U.S. or abroad that involves NIMBY or any other environmental justice-type issues. Share what you find with the class and provide the source. Be sure to include:
    1. The country, region, and/or state.
    2. What the conflict was.
    3. Was there a resolution or not? Provide a brief overview.

Be sure to address all Discussion Board topics in an original, well-thought-out, respectful manner. Main posts should fully and completely discuss each question posed and make frequent, informed references to this unit’s material. Engage in ongoing, productive conversation by responding to a minimum of two classmates per topic.

Non-Profit Organization Research Paper

Research Assignment 5

EVR 1001 Fall 2020

This document includes the fifth research assignment worth 20 points. Follow the directions below for the assignment and submit to the BlackBoard drop box by the due date of Monday, Dec. 14.

For this project you will be researching a “NGO” (non-governmental organization) or interchangeably called a “NPO” (non-profit organization). NGO/NPO’s are often referred to as “grassroots” organizations as well and exist to support or advance a certain cause. The Red Cross, for instance, is a very large NGO/NPO having much political influence and helping millions of people during times of crisis. Others are much smaller and work peacefully while others may be quite radical in their actions. If you further wish to know what constitutes a NGO/NPO consult with either of these two links: https://www.investopedia.com/terms/n/non-profitorganization.asp or https://en.wikipedia.org/wiki/Nonprofit_organization. The NGO/NPO you choose must relate to the goals and objectives of this course as part of working towards an environmentally sustainable society and/or environmental conservation or protection. Here is what you need to do:

1) Find an NGO/NPO to research. Remember, it must be related to the goals and objectives of EVR 1001.

A

2) Describe the purpose/goals/mission of the NGO/NPO explaining why the NGO/NPO was founded. (4 pts)

3) Who (individual or group) founded the NGO/NPO and when? (2 pts)

4) How many members represent the NGO/NPO? (2 pts)

5) How is the NGO/NPO funded? (2 pts)

6) Explain how members go about accomplishing their purpose/goals/mission, that is, how do

they conduct their activism? Do they conduct outreach education, demonstrations, physical

labor, etc.? (4 pts)

7) Describe specific examples or instances of the groups’ activism to accomplish their goals.

You may have to do a little searching for this one; look for news stories, articles, web sites,

etc. that may describe specific examples, instances, dates. (4 pts)

8) Would you consider joining this organization? Explain why or why not? (2 pts)

Type this information up in a question/answer format as above and submit to the Blackboard drop box by Monday, Dec. 14.

Complete your own work. For people that may incidentally choose the same NGO/NPO, I will carefully be scrutinizing those using similarity indexes such as the SafeAssign software and/or manual comparison. Finally, as always, be aware of plagiarism and cite any sources that you may quote or closely paraphrase.

Title of Paper

Note: The following introduction should remain in the research project unchanged. Delete this note before you begin.

Senior leadership at Sun Coast has identified several areas for concern that they believe could be solved using business research methods. The previous director was tasked with conducting research to help provide information to make decisions about these issues. Although data were collected, the project was never completed. Senior leadership is interested in seeing the project through to fruition. The following is the completion of that project and includes the statement of the problems, literature review, research objectives, research questions and hypotheses, research methodology, design, and methods, data analysis, findings, and recommendations.

Statement of the Problems

Note: The following statement of the problems should remain in the research project unchanged. Delete this note before you begin.

Six business problems were identified:

Particulate Matter (PM)

There is a concern that job-site particle pollution is adversely impacting employee health. Although respirators are required in certain environments, PM varies in size depending on the project and job site. PM that is between 10 and 2.5 microns can float in the air for minutes to hours (e.g., asbestos, mold spores, pollen, cement dust, fly ash), while PM that is less than 2.5 microns can float in the air for hours to weeks (e.g. bacteria, viruses, oil smoke, smog, soot). Due to the smaller size of PM that is less than 2.5 microns, it is potentially more harmful than PM that is between 10 and 2.5 since the conditions are more suitable for inhalation. PM that is less than 2.5 is also able to be inhaled into the deeper regions of the lungs, potentially causing more deleterious health effects. It would be helpful to understand if there is a relationship between PM size and employee health. PM air quality data have been collected from 103 job sites, which is recorded in microns. Data are also available for average annual sick days per employee per job-site.

Safety Training Effectiveness

Health and safety training is conducted for each new contract that is awarded to Sun Coast. Data for training expenditures and lost-time hours were collected from 223 contracts. It would be valuable to know if training has been successful in reducing lost-time hours and, if so, how to predict lost-time hours from training expenditures.

Sound-Level Exposure

Sun Coast’s contracts generally involve work in noisy environments due to a variety of heavy equipment being used for both remediation and the clients’ ongoing operations on the job sites. Standard ear-plugs are adequate to protect employee hearing if the decibel levels are less than 120 decibels (dB). For environments with noise levels exceeding 120 dB, more advanced and expensive hearing protection is required, such as earmuffs. Historical data have been collected from 1,503 contracts for several variables that are believed to contribute to excessive dB levels. It would be important if these data could be used to predict the dB levels of work environments before placing employees on-site for future contracts. This would help the safety department plan for procurement of appropriate ear protection for employees.

New Employee Training

All new Sun Coast employees participate in general health and safety training. The training program was revamped and implemented six months ago. Upon completion of the training programs, the employees are tested on their knowledge. Test data are available for two groups: Group A employees who participated in the prior training program and Group B employees who participated in the revised training program. It is necessary to know if the revised training program is more effective than the prior training program.

Lead Exposure

Employees working on job sites to remediate lead must be monitored. Lead levels in blood are measured as micrograms of lead per deciliter of blood (μg/dL). A baseline blood test is taken pre-exposure and postexposure at the conclusion of the remediation. Data are available for 49 employees who recently concluded a 2-year lead remediation project. It is necessary to determine if blood lead levels have increased.

Return on Investment

Sun Coast offers four lines of service to their customers, including air monitoring, soil remediation, water reclamation, and health and safety training. Sun Coast would like to know if each line of service offers the same return on investment. Return on investment data are available for air monitoring, soil remediation, water reclamation, and health and safety training projects. If return on investment is not the same for all lines of service, it would be helpful to know where differences exist.

Findings

After providing a brief introduction to this section, students should discuss the findings in the context of Sun Coast’s problems and the associated research objectives and questions. Important Note: Students should refer to the information presented in the Unit VII Study Guide and the Unit VII Syllabus instructions to complete this section of the project. Restate each research objective, and discuss them in the context of your hypothesis testing results. The following are some things to consider. What answers did the analysis provide to your research questions? What do those answers tell you? What are the implications of those answers? Delete these statements before you begin.

Example:

RO1: Determine if a person’s height is related to weight.

The results of the statistical testing showed that a person’s height is related to their weight. It is a relatively strong and positive relationship between height and weight. We would, therefore, expect to see in our population taller people having a greater weight relative to those of shorter people. This determination suggests restrictions on industrial equipment should be stated in maximum pounds allowed rather than maximum number of people allowed.
