I came across a question from the demo exam asking about the cheapest alternative to a curtainwall system.
To my understanding, the storefront system and window wall system are essentially the same except that window wall describes windows that span floor to floor and storefront describes the same but on the ground floor application. In this case, window wall will be the best alternative to curtainwall system. However, the NCARB says the answer is storefront.
Can anyone help me with this? Thanks!
