FAQs about EAp2 :

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?

Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?

Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?

CS-v4 EAp2:Minimum energy performance

Tenant IT equipment

Hello,

 

I have a question regarding LEED v4 Core & Shell, EA P2 - Minimum energy performance.

We’re currently involved in several LEED Core & Shell Certifications of office buildings. Typically in these buildings the scope of works of C&S includes the installation of central HVAC equipment providing ventilation, chilled water and hot water to the tenanted spaces. In some projects, in addition to these services, the central HVAC system also provides condensation water to the tenanted spaces.

 

Considering the Core & Shell scope, it is not possible to predict if the tenants will have (or not) relevant IT equipment and if they will install the associated HVAC equipment to provide the required cooling to the IT rooms. The question is: in this context, the IT equipment and its HVAC (process energy) can be excluded from the energy simulation, or is it mandatory to include it in the model? If so, how?

 

Best regards.

In general you do not have to assume the installation of IT equipment beyond a typical plug load. However, I would not necessarily start there. For this particular project is the typical tenant likely to have IT equipment that requires cooling to be installed in the IT rooms? If the answer is yes then I would make some assumptions and model them identically.
