Hi, Hi, in EU most countries have feed-in-tarriffs, which reimburse the owner for energy produced at a higher rate than the cost of energy.

On a C&S healthcare building, we simulated the receptacle load based on CS Appendix 2, Table 1, as the appendix directed.

In a LEED CS 2009 building energy simulation we are modeling the building envelope to test performance (only the building envelope).

Hi, I have a doubt on how to model the baseline HVAC system of a specific shopping center. In this project, it was specified the HVAC system which serves the mall building and some of the stores.

Hi LEED Users, I hope it is correct to model renewable energy system only in proposed building as our advantage against baseline. Please coorect me if I'm wrong. Thanks!
