Impact of surrounding environments and vegetation on wind comfort assessment of a new tower with vertical green park

Modern architectural concept of “vertical forest” boosts the tendency including permeable and green spaces in buildings its surroundings. However, whilst generally make cities more ecofriendly, it is insufficiently known to which extent surrounding environment vegetation may positively or negatively influence pedestrian-level wind comfort quality amidst historical well-settled urban layouts. This was scope present study for wind-tunnel (WT) testing 3D RANS simulations were performed on two facing towers Medellìn (Colombia), order (i) investigate field around towers; (ii) compare performance WT analysis; (iii) evaluate impact (iv) mitigation effects comfort. tests a scaled model (1:250) without surrounding, 12 directions 3 sets measurement positions. The same case (i.e. CFDs) with CFDd) simulated by RANS. Next, an implemented CFDd (i.e., CFDd-V) three LAD values. Overall, had significant assessment. showed better-quality class than CFDs. CFDs satisfactory agreement similar class. provided remarkable improvement mainly set 1 2.
