- help me with this Question for revision purposes and as well with citation The office building was built in year 2017 and has not obtained any Green Mark certification before. The office building is occupied by a single tenant/entity. The building management team had done an analysis of the building’s energy performance by extracting the data from the various systems. The current performance and findings of the systems are listed in Appendix A. The client is considering to have the building undergo retrofitting to improve the building’s energy performance. The objective is to achieve Green Mark Gold Plus under the new Green Mark 2021 framework. For part (a) below, you are to use Pathway 1: EUI for this. (a) As part of the feasibility exercise, you are to interpret the current performance of the existing building based on the data available (Refer to Appendix A).

The activated sludge system (aeration tank and secondary clarifier) you design needs to remove 85% of the incoming BODs from the primary effluent, giving a final concentration of 30.0 mg BODs/L exiting the system. Your design will maintain a concentration of 2500 mg VSS/L and F/M ratio of 0.5 g BOD/g VSS d in the aeration tank. In an effort to keep the waste activated sludge low in water, only about 0.1% of the primary effluent flow (Q) exits the WAS line. The secondary effluent has a flow rate of 9990 m³/d. What volume (in m³) will the aeration tank need to be? Write out all equations and state any assumptions as needed. Primary effluent: Q.

- b) Workers in a 1000 m³ processing room in a plastics factory are exposed to vinyl chloride (C2H3CI) gas, which is emitted when the plastic pellets are heated to make the final products. a) If the air change rate in the room is 0.21/h and the source strength of C2H3Cl is 68 mg/h, what is the steady state concentration of C2H3Cl (in mg/m³ and in ppmv) in the room at 25°C and 1 atm? Assume that C2H3Cl is conservative and that the concentration of the gas in the ambient air is zero.

- Three transportation projects have been proposed to increase the safety in and around a residential neighborhood. Each project consists of upgrading existing street signing to highly retroreflective sheeting to increase visibility. The following table shows the initial construction costs, annual operating costs, useful life of the sheeting, and salvage values for each alternative. Annual Operations and Maintenance Initial Construction Alternative Cost ($) 1 16,000 2 3 7,500 18,000 Costs ($) 2,000 3,750 2,000 Useful Life (years) Salvage Value ($) 10 5 10 6,000 850 7,300 Assume that the discount rate is 10 percent. Calculate the present worth (in dollars) for each alternative. (Assume for Alternative 2 that new sheeting must be purchased at the end of the first five years, and that all operations and maintenance costs are due at the end of each year.)
