We find that weather has the strongest correlation with optimal storage sizes and the size of energy conversion systems. They are also affected by the usage intensity of certain building zones. In addition, the storage sizes influence each other in the complex building energy system of our use case.
Energy Efficiency vs. Energy Intensity | Department of Energy
Energy Intensity is measured by the quantity of energy required per unit output or activity, so that using less energy to produce a product reduces the intensity. Energy Efficiency improves when a given level of service is provided with reduced amounts of energy inputs or services are enhanced for a given amount of energy input.

What is Water Use Intensity (WUI)?
If you benchmark water use in Portfolio Manager, one of the key metrics you''ll see is water use intensity, or WUI. Essentially, the WUI expresses a building''s water use as a function of its size or other characteristics. For most property types in Portfolio Manager, the WUI is expressed as gallons per square foot per year.

Introduction. Buildings account for over one-third of the global energy consumption [1]. In order to reduce associated CO 2 emissions, the use of renewable energy sources (RES) is essential. However, RES are subject to the volatile power and heat generation of wind and solar energy plants and thus to uncertainty on the generation side.
