The document provides information on modeling and evaluating the energy performance of a building located in Bainbridge Island, Washington. It includes: - Details on the building design, contractors, and specifications from different software simulations. - Results of the simulations showing monthly energy consumption by end use and the total energy usage in different software programs. - A comparison of energy usage for the building with a furnace versus a heat pump system, both with standard and larger windows. - Breakdowns of heating and cooling loads, energy usage, and plant systems for the building when modeled in EnergyPlus and IES Virtual Environment simulation tools.

6. Description
For larger area of window with furnace and heat pump systems
When increasing the area of windows, the design with heat pump decreases more energy because it not only decreases heating energy but also
reduces hot water consumption
