Summary The purpose of this design project is to design building services of the Architecture and Built Environment’s Marmont Centre. Building services includes a low-temperature-hot-water (LTHW) gas central-heating system, indirect hot and indirect cold water services, foul and rain water drainage, artificial lighting and basic control systems for the building services.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
