TRÆ in Aarhus, Denmark, is built in part from reused construction waste. Designed by Lendager Architects for Kilden & Hindby and PFA Ejendomme, in collaboration with MOE Consulting Engineers and Kaj Ove Madsen, Aarhus Municipality and Realdania, it is due to be completed 2024. Reuse and recycling innovations in the facade include the use of decommissioned composite wind turbine blades for solar shielding, aluminium roof plates for the facade, wooden cassettes, wood insulation, low-carbon concrete and insulation from waste textiles. The reused aluminium facade comes from two different renovation projects, where they had been discarded, plus water-damaged panels from a supplier. Standing 78 m high, the structure is steel, concrete and timber. All materials have been thoroughly tested so that they continue to meet the requirements and regulations.

Spidsen af ​​Nordø (Tip of Nordø, Redmole Spidsen), Denmark, by Cobe Architects, Vilhelm Lauritzen Architects and Tredje Natur, completed 2023. The facade concept for the cylindrical structure was designed with the aim of creating good daylight conditions throughout the building. To reduce glare, facade elements are narrower towards the west, south and east of the building, where the facade is the most exposed to daylight. Towards the west, north and east, the facade gradually opens up, letting in more light. Thus, the six individually angled facade elements vary in size and glazing ratios based on hour-by-hour weather simulations. The prefabricated solar control glass units in anodised aluminium were manufactured and installed by Feldhaus Fenster + Fassaden.

Equestrian statue of Francisco Pizarro, Trujillo, Spain. Lost wax cast in bronze, the surface have evolved a variegated green patina (verdigris) over many years. This layer develops naturally on the surface and protects the substrate beneath from further corrosion.

NEMO (National Center for Science and Technology), Amsterdam, by Renzo Piano, completed 1997. It is clad in green patinated copper. The process of patination is very slow, taking many years to become green and only if the conditions are right. So, the copper is pre-patinated using a chemical process to give the hardwearing and weather resistant layer on the surface a head start prior to installation.

Copper with a small amount of tin (Sn, 3.5-4.5%) produces a rich copper-red colour cladding. A brown-red surface oxidation is typical for this alloy, with darker undertones. The material then gradually changes to dark brown - the patina forms more slowly than with pure copper.

The Silo in Copenhagen, by Cobe, completed 2017, features a galvanised steel facade hung on the original reinforced concrete structure of the industrial grain silo, mounted on large steel brackets. The prefabricated batch galvanised steel units, manufactured by Skandinaviska Glassystem, act as a climate shield and provide a dramatic appearance reflecting the surrounding light while forming the distinctive zinc patina. A steel with a specified minimum silicon content to achieve at least 100 microns of galvanised coating was used for the 3 mm thick facade plates. It was batch galvanised, as opposed to using pre-galvanised sheet, to avoid exposed steel edges after cutting which would corrode. It is estimated the galvanised steel will last 50 years and can be dismantled and re-galvanised to extend its life.
