Energy Plus & Open Studio Class • Tuesday (November 20), 5:45 PM • Computer lab ECJ 3.402 • Instructor: Wesley Cole
Lecture Objectives: • Review the midterm exam • Project related topics: • Discuss the HVAC system configuration in eQUEST • Discuss the life cycle cost analysis • Learn about empirical modeling
What are the reasons for energy simulations? • System Development (research) • Building design (evaluate different design solutions) • Economic benefits • Budget planning
Life Cycle Cost Analysis • Engineering economics
Parameters in life cycle cost analysis Beside energy benefits expressed in $, you should consider: • First cost • Maintenance • Operation life • Change of the energy cost • Interest (inflation) • Taxes, Discounts, Rebates, other Government measures
Example • Using eQUEST analyze the benefits (energy saving and pay back period) of installing - low-e double glazed window - variable frequency drive in the school building in NYC
What are the reasons for energy simulations? • System Development (research) • Building design (evaluate different design solutions) • Economic benefits • Budget planning
For budget planning Empirical model Load vs. dry bulb temperature Measured for a building in Syracuse, NY Model For average year use TMY2 =835890ton hour = 10.031 106 Btu
