Olga Porras January 21, 2024 CO320 Unit 2 Assignment Chapter 4: 1. Explain why you normally include more than the minimum requirements when installing a sanitary drainage and pipe venting system? IInstalled pipe venting systems are crucial for sustaining the safety and functionality of a building’s plumbing system. It is important to go above and beyond when installing sanitary drainage and pipe venting systems as they work with one another to ensure the success of the building. Pipe filtration systems and pipe drainage systems are an important part of a home's plumbing system to safely remove and dispose of wastewater and sewage from the home. In order for your system to run smoothly and safely, it is important to include more than the minimum requirements during installation. For example the building codes generally set minimum requirements for plumbing systems, but exceeding these requirements can ensure that your system meets all required safety standards. Additional parts or components, such as larger pipes or additional heaters, help improve system performance. Adding additional features or capabilities during installation will help future-proof your system, ensuring it can accommodate changes and upgrades that may be needed in the future. Adding additional safety features, such as backflow prevention or alarms, can ensure the system operates efficiently and reduce the risk of health hazards and environmental damage. Chapter 5: 2. Define the water supply fixture unit system, by providing an example of how it is used to design the sizes of water pipes use in relation to the five defining factors? The water supply fixture unit system (WSFU) is a method used to determine the water demand and sizing of water supply pipes for a building or facility. It calculates the water demand of plumbing fixtures by the number of units and then adding them all together to account for the whole building. There is five defining factors which are fixture unite value, number of fixtures, durian of use, simultaneous demand, and friction loss.Fixture unit value is based on its flow rate and usage. They are all different as it depends on the type itself. Number of fixtures is the total number of each fixture type in total for the whole building.The total number of fixture type is then multiplied by the fixture unit for the fixture type.Duration of use is the amount of time each fixture is estimated to be used per day.Simultaneous demand is the number of fissures that are estimated to be used at the same time. This is important as it is based on the water

availability in this case. Which can help determine the demand of the water as a whole which would allow to choose the proper pipe size. Friction loss can increase or decrease it all depends. This is important as the pressure can affect the pipes if it is the incorrect pipe for the building. Pressure can strain the pipe and cause a safety hazard all around EXAMPLE: An office space that has 2 toilets ( 3 fixture units each), 2 bathroom sinks (1 fixture unit each) and 1 kitchen sink with (2 fixture units). Toilets: 2 fixtures*3 fixtures units per fixture = 6 WFSU Bathroom Sinks: 2 fixtures * 1 fixtures units per fixture = 2 WFSU Kitchen Sink: 1 fixture * 2 fixtures units per fixture = 2 WFSU Total WSFU = 10 WSFU. Chapter 6: 3. Describe in detail and by way of examples the significance of the Americans with Disability Act? The ADA prohibits discrimination against people with disabilities and requires that public spaces, workplaces, and parking spaces be accessible to people with disabilities. These laws help ensure that people with disabilities are not discriminated against and have access to the same opportunities as people with disabilities. The ADA improves access to public spaces, transportation, education, and employment, and helps create an inclusive and just society for people with disabilities. 1.Employment: The Americans with Disabilities Act prohibits employers from discriminating against people with disabilities in all aspects of employment, including hiring, promotion, and compensation. Employers must provide reasonable accommodations to employees with disabilities to ensure they can perform their duties. 2.Public accommodations: The ADA requires that public places such as restaurants, stores, and government buildings be accessible to people with disabilities. Transportation: The ADA requires that transportation services such as buses and trains be accessible to people with disabilities. This includes providing disabled seating, lifts or ramps for wheelchairs, and other accommodations. 3.Education: The ADA requires schools and colleges to provide accommodations and support services for students with disabilities. This includes providing the facilities and technology available, as well as specialized help and support services. 4.Technology: The ADA applies to websites and other forms of digital technology that must be accessible to people with disabilities. This includes providing alternative text for images, subtitles for videos, and other accommodations to make digital content accessible to people with disabilities. Chapter 7: 4. Review and describe how a sanitary plumbing systems tested and inspected to include the equipment use and the required pressure test and what actions you take if the test fails?

A sanitary plumbing system is a system that provides potable water for human consumption and contains a series of pipes, fixtures, and appliances such as sinks, toilets, showers, and bathtubs. It is important to test and inspect sanitary plumbing systems to ensure that they are functioning properly and to identify any potential problems.The first step in testing and inspecting a sanitary plumbing system is to ensure that all equipment is properly used. This includes checking all fixtures for leaks, making sure that all traps are full of water, and verifying that all appliances are operational.The next step is to perform a required pressure test. This test is used to ensure that the sanitary plumbing system is able to handle the required pressure and that all connections are tight. The test is performed by connecting a pressure gauge to the system and then gradually increasing the pressure until the gauge reads the required amount. If the test fails, then the system must be repaired or replaced.If the test fails, then the following actions must be taken: Inspect the system for any leaks or damage,repair any leaks or damage found,repeat the pressure test.If the pressure test still fails, then the system must be replaced.Testing and inspecting a sanitary plumbing system is an important part of ensuring that it is functioning properly. By completing such tests you are able to ensure that the plumbing system is safe to use. It is important to fix and then retest to ensure that the system is sustainable and able to function accordingly. What is the source of the requirements for a sanitary sewerage and venting systems found and defend why is it important to meet or exceed these requirements? The requirements for a sanitary sewerage and venting systems are found typically in the national regulations and codes of practice. It is important to check the federal,state and city regulations as they all must be followed to be able to successfully pass inspections. Such regulations are there based on past experiences. It is important to follow them as they are there to ensure the safety of the public. Regulations are also there to ensure that the operation of such systems are effective and logical while still maintaining the integrity of the environment. Such standards/regulations are there to decrease the risk of contamination that can lead to pollution. Both Sanitary sewage systems and venting systems go hand on hand with each other. Sanitary sewerage systems serve to safely dispose of the wastewater. They collect the waste from sinks, toilets, showers,etc and then transport it to the treatment facility. Once it gets to the facility the wastewater gets cleaned and treated. Venting systems help maintain the sewer gasses away from building.Which could cause health problems. By meeting or exceeding the requirements we ensure that these systems are designed and installed to the highest standards possible and allow them to function properly without damaging the public or the environment.

Chapter 8: 6. Compare and contrast the requirements for comfort in an air circulation system in order to provide comfort for the occupants. Air circulation systems play a critical role in maintaining occupant comfort in a variety of indoor spaces, including residential, commercial, and industrial environments. These systems are responsible for regulating indoor temperature, humidity, and air quality. However, the comfort requirements of an air circulation system vary depending on the needs and preferences of the occupants and the specific environment in which the system is installed. Commercial and industrial environments, on the other hand, may require different requirements depending on the specific process, equipment, number of people in the room, and other factors. Air circulation systems in residential buildings must be able to reduce humidity to comfortable levels, typically around 40- 60% relative humidity. This is very important to prevent mold growth, maintain indoor air quality, and promote overall comfort. In contrast, commercial and industrial spaces may require more stringent humidity control as certain materials and machinery are sensitive to moisture. Therefore, air circulation systems in these environments can be equipped with additional dehumidification mechanisms to maintain a controlled and stable environment. Air quality is an important factor for occupant comfort. This is achieved through a filter system of varying efficiency, ensuring a cleaner and healthier indoor environment. Conversely, commercial or industrial air circulation systems may prioritize function over noise reduction, and noise is often an issue in such environments. In fact, some industrial processes can generate high levels of noise, requiring additional soundproofing measures to ensure a comfortable working environment for residents. Energy efficiency plays an important role in both residential and commercial air circulation systems, although priorities and requirements differ. In commercial environments, energy efficiency plays a role in reducing total cost of ownership while ensuring user comfort. In summary, the comfort requirements of air circulation systems depend not only on the specific environment in which the system is installed, but also on the needs and preferences of the occupants. Residential systems emphasize consistent temperature control, reduced humidity, good air quality, low noise levels, and energy efficiency, while commercial or industrial systems require more stringent control measures, additional filtration and Soundproofing is required. Understanding these requirements and incorporating them into your air circulation system will ensure that occupants enjoy optimal comfort and well-being in their indoor spaces. 7. Categorize the reasons for poor indoor air quality and examine the best ways to control indoor air pollution? Indoor air quality (IAQ) refers to the quality of the air in a building, which has a significant impact on the health, comfort and productivity of occupants. There are many reasons for declining indoor air quality, including sources of pollution, poor ventilation, and poor home maintenance. The causes of poor indoor air quality can be divided into the following categories: Chemical pollutants, common sources are cleaning products, paints, solvents, pesticides, and organic chemicals (VOC). They emit pollutants such as carbon monoxide, nitrogen dioxide, and particulates that cause breathing problems. A lack of ventilation results in a lack of fresh air, which can't effectively dilute pollutants outside, resulting in the creation of pollution. Poor hygiene and lack of regular cleaning.

Cleaning can be a breeding ground for dust mites, mold and other contaminants. Improper humidity control results in excess moisture and poor water quality that encourages mold growth and releases harmful spores into the air. Inadequate maintenance of HVAC systems: Dirty filters, leaky pipes, and broken appliances can reduce indoor air quality. The best way to control indoor air pollution is to identify and eliminate pollution sources whenever possible. Smoking indoors or reducing the use of chemical products. Ensure adequate ventilation during activities that emit contaminants, such as cooking or using cleaning equipment. This may include using mechanical cooling systems and opening windows when outside conditions permit. Inspect and maintain your air conditioning system to ensure it is working properly. Cleaning and Filtering: Install and maintain air filters in your HVAC system to capture and remove particulates and contaminants. Prevent damp growth by controlling humidity and prevent dampness and leaks by checking and fixing damp sources. Poor indoor air quality affects the health and well-being of building occupants. It is important to understand the causes of poor indoor air quality, including sources of pollution, poor ventilation, and poor housekeeping. By implementing source control measures, improving ventilation, using air cleaning strategies, and managing effective humidity, indoor air pollution can be significantly reduced, making it a better place for everyone to live. , or of the work environment. 8. Explain how the testing is done for a control indoor air pollution to include the equipment used and how long the pressure must be maintained? Testing and control procedures are critical to a safe and healthy environment. The purpose of this article is to describe experimental methods for detecting, measuring and controlling indoor air pollution, including the equipment used and measurement periods. It is important to identify and measure the damage found inside the building before taking control measures. Air quality monitoring: This device can measure and analyze the amount of various pollutants, including carbon dioxide, organic compounds, particulate matter, etc.Air Monitoring: These devices are used to monitor and measure the levels of other gasses such as carbon monoxide, nitrogen dioxide, radon and other harmful gasses. Good working practice requires careful consideration of many factors, including retaining the correct information within the room to prevent dangerous migration.Ventilation system: can replace indoor air with fresh air. This will reduce the amount of pollutants and maintain the air quality inside the house. Filter: Air filters improve indoor air quality by filtering and removing particles and pollutants. Pressure: It is important to maintain an energy balance within the house so that waste does not move from one place to another. To ensure good ventilation of the affected area and prevent the spread of contamination, pressure compensation technology (such as air conditioning) can be used to create pressurized areas. On the other hand, negative pressure zones can be placed in areas such as laboratories or isolation rooms to keep contaminants away from designated areas. The length of time that internal pressure can be maintained depends on a variety of factors, including the severity of air pollution, system capacity, and the specific needs of the area in question. Regular monitoring and evaluation will ensure that energy changes remain within acceptable limits and adverse impacts are controlled. Testing and monitoring programs are necessary to achieve and maintain indoor air quality at safe and acceptable levels. Pollutants can be better detected and measured with the right equipment, including air quality monitors, particle

counters, air quality monitors and fuel imaging cameras. In addition, controls such as ventilation, filtration, and pressure control can also reduce contamination. Remember, by following these steps, we can create a healthy indoor environment and protect human health from the harmful effects of indoor air pollution.
