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?

NC-v4 EAp2:Minimum energy performance

ASHRAE Baseline HVAC System

Hi all,

Can I pick someone's brain about which ASHRAE Baseline HVAC system we should be selecting for a Hospitality project we are working on?

This is a major renovation of an existing building which will be converted to a 7-storey building. It will comprise 3 floors of Hotel rooms (2,100 m2, in total) and 2 floors of offices and auxiliary spaces (1,000 m2, in total). There will also be 2 underground floors (total area of 750 m2) which will include mostly MEP plantrooms, storage areas and a couple of massage and sauna rooms.

We would like to know if we should be going with System 1 (Building Type: Residential) for the whole building or we would be better off going with System 1 only for those floors with hotel rooms and maybe selecting System 3 for the rest of the building?

Any advice would be of great help.

Thanks.

Kind regards,

Nikos

You should model a system 1 for the entire building unless one of the exceptions to G3.1.1 applies. If any apply then you must follow the guidance there.
