Summary

 

The State University School of Business is a new educational building located in Detroit, MI. The 122000 square feet building have a maximum of total occupancy load of 423 occupants, which classroom will have max. occupant of 240 people, boardroom 55 people, storage 2 people and business area of 126 people. The report is to analyze the existing building energy and cost efficiency and propose different systems that could potentially increase the building energy and cost efficiency. Two breadth studies will also be done, the calculation will include knowledge that has been taught previously, and the Trace 700 model will be done and use the result into the analysis for each alternatives and breadths.

​

The two alternatives will be studied for the building system, one is the Ground Source Heat Pump (GSHP) option, the other is the variable refrigerant flow (VRF) option. The existing building uses the water source heat pump, the system has a low initial cost, and a relatively high operation and maintenance cost. The two alternatives will be studied, talk about if the system will be more efficient, both alternatives will explain how the system works, analyze the system cost and energy consumption. 

​

Two breadth will include one of rainwater harvesting system analyze, and the other of the building envelop study. The rainwater harvesting system will analyze how much rainwater will the building get and come up with the strategies on sizing tank and estimate the initial cost of the water tank and decide where to use the water. The payback period should be calculated.

​

The building envelop study will focus on compare the existing building exterior wall system to a new exterior wall system. The purpose is to make the new building system to reduce the building heat gain/ loss, so the building cooling and heating loads will be reduced.
