Lecture Objectives: Discuss Project 1 and Final Project Learn about Photo Voltaic systems Discuss HW3

Residential buildings (Part a & b in Project 1) It is very expensive to optimize each residential building We optimize example buildings to develop local codes UT Solar Decathlon 2007 Home Research Lab Test house (PRC)

Modeling for optimization of Home Research Lab (PSP)

Energy consumption in Austin’s residential house Analyze impact of: envelope Internal loads HVAC systems Conduct life cycle const analysis See handout section

Commercial Buildings Building 1) Optimization of building envelops glass area ,shading,…. 2) Effect of internal loads on energy consumption .................. Systems 1) Impact of HVAC systems 2) Design of solar system (PV or hot water) …………….. Life cycle cost analysis in each project

Final project topics: Software (eQUEST, or BeOpt, EnergyPlus) based Your model bases (modeling in Matlab like in HWs 1&2) Energy analysis of building form Integrated design course Any other building or building system Impact of thermal mass on high rise buildings Residential commercial building optimization for different climate Thermostat reset impact …. Detail Modeling (your model) Heat recovery systems, Attic problem, Mass transfer (moisture,…) ….. Your ideas…

Requirement for the project Undergrad students: Team project (3 members) Grad students: Individual effort Submit till Thursday: Final project group members Project title One paragraph (200-300 words) about the project then Meetings on Thursday and Friday to define: - Project objective Methodology Expected results
