3. What is the best energy source for water heating for a commercial setup in urban areas here in our country if sustainability is important? Explain the
answer. (15 pts)

Besides from oil, coal and natural gas, Solar energy is the best alternative for energy source of water heater especially that our country is a tropical
country. Additionally, there are less tress in urban areas and are more expose in sunlight which is the best reason to use solar energy.

4. Suppose you are to work on the plumbing and sanitary trade project of an eleven (11) – story mixed-use (restaurant, B.P.O., clinic, or another legal
purpose) commercial building. What is the list of materials and equipment you are going to obtain for the project? (15 pts)

First, I would include pump, given that this is a 11-story building it will require a pump for the water to be able to reach the top floor. Next is Water filter
or purification, if it’s a restaurant, I will prioritize cleanliness and the well-being of those people who will use the infrastructure. Lastly water heater, for if
it were to be a condo, I would include water heater for tenants who hate showering with cold water every morning

5. Make a case for why studying plumbing and sanitary engineering utilities is essential to your program (BS CE or BS EnSE). (10 pts)

Plumbing is important part in construction because it keeps things sanitary. They are responsible for designing sewerage systems that helps maintain
cleanliness. Having a good understanding how plumbing works give ideas to engineers on how they will design a building. As CE, plumbing is essential for us
to know how we will construct the building with proper sewerage system.
