Via 57 West was listed as one of the 7 most eye-catching new residential buildings in New York City according to Haute Residence. Contrarian Micro Textures’ InvariMatte® micro texture was used to clad the entire exterior of the building. Check out the article, here:
Condensation heat transfer characteristics of near-azeotropic refrigerant R410A inside the horizontal copper and stainless steel EHT series tubes were measured. All three dimensional two-layer two-side enhanced tubes have deep-textured surface structures. Tests were conducted at an average saturation temperature of 45 °C; over a mass flux range of 100–450 kg/(m2·s); with an inlet quality of 0.8 and outlet quality of 0.2. Condensation heat transfer coefficient of the copper 1EHT tube is about 39–47% higher than that of a stainless steel one, showing a beneficial effect of high thermal conductivity material.

Results are presented here from an experimental investigation on tubeside condensation and evaporation heat transfer that took place in three Vipertex® stainless steel enhanced heat transfer tubes (1EHT-2, 2EHT-2 and 4EHT). Equivalent outer diameter of the tube was 9.52 mm (0.375 in) and the inner diameter was 8.32 mm (0.3276 in).
