The Whole Building Simulation option is used to meet the Energy and Atmosphere Prerequisite, Minimum Energy Performance for a hospital project.This option involves creating a detailed computer model of the building to simulate its energy performance and identify opportunities for improvement.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources1

The Energy and Atmosphere Credit, Demand Response rewards projects that participate in demand response programs that aim to reduce peak electricity demand and shift the load to off-peak periods. The LEED v4 Reference Guide for Building Design and Construction states that "the intent of this credit is to increase participation in demand response technologies and programs that make energy generation and distribution systems more efficient, increase grid reliability, and reduce greenhouse gas emissions"1. The project team must either implement a permanent demand response program or develop a plan to implement a program within a year of occupancy. The project team must also demonstrate that the building has the capability to reduce its peak electricity demand by at least 10% in response to demand response signals.

The Materials and Resources Credit, Construction and Demolition Waste Management aims to reduce the amount of construction and demolition waste disposed of in landfills and incineration facilities by recovering, reusing, and recycling materials. According to the LEED v4 Reference Guide for Building Design and Construction, one of the options to achieve this credit is to divert at least 50% of the total construction and demolition material from disposal and recycle or salvage at least three material streams1. Therefore, salvaging and recycling 50% of the existing materials (based on volume) generated during site demolition for three material streams would contribute to earning this credit. The other options are not related to this credit, but to other credits or prerequisites, such as Sustainable Sites Prerequisite: Construction Activity Pollution Prevention1, Materials and Resources Prerequisite: Storage and Collection of Recyclables1, and Materials and Resources Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials1.

The commissioning (Cx) agent must have completed the commissioning process activities for a minimum of two similar projects in order to meet the minimum qualifications for Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification. This is stated in the LEED v4 Building Design + Construction Guide, under the section “Energy and Atmosphere Credits Overview”. The guide also provides examples of similar projects that can be used as references for commissioning.
