This prerequisite focuses on the elimination of CFC-based refrigerants that contribute to ozone depletion in HVAC&R equipment. Although fire suppression systems are covered by EAc4, you're not required to consider them for this prerequisite. Doing so in conjunction with EAc4 is a good idea, however.

This credit promotes efficient, high-performance lighting systems through increased controllability for building occupants. Allowing individuals control over the lighting levels in their workspaces can enhance their comfort, productivity, satisfaction, and overall wellbeing.

Better lighting controls can also increase the efficiency of your lighting system by focusing on task lighting rather than unnecessary ambient lighting, and can reduce energy use due to cooling loads by allowing occupants to turn off lights when leaving their space or when daylight is sufficient.

EAp2 requires that 50% (by power rating) of new equipment and appliances purchase for the LEED-CI scope of work be Energy Star labeled. Projects that go beyond the 50% requirement can achieve up to four additional points under EAc1.4 by specifying 70%, 77%, 84%, or 90% Energy Star equipment.

• Remediation can be costly, but funding and incentives are often available through local cleanup and governmental agencies. 
• Schools are required to implement a Phase I ESA for SSp2: Environmental Site Assessment and can only achieve this credit by conducting a Phase II ESA and carrying out the required remediation or by remediating asbestos.

The intent of this credit is to reduce the development pressure on undeveloped land by encouraging development of land that has access to existing infrastructure and services. 

This credit is straightforward. You can earn it if your site has been designated a brownfield by a state, local or federal agency and if the site is remediated to meet appropriate standards for development. 

By encouraging Commercial Interiors projects to commit to a long-term occupancy, this credit aims to reduce the amount of materials that are used in successive tenant fit-outs, eliminating the waste that is generated by moves and new construction. A secondary benefit of longer occupancy periods is that tenants have a greater incentive to make longer-payback upgrades for greater energy and water efficiency.
