Welcome to ‘Stainless Solutions’ from IMOA. Each month, we will cover a different stainless steel issue with tips on design and specification, and links to technical resources. This month we are highlighting the advantages of second-skin façade weather screens.
|Second-skin façade weather screens|
Second-skin façade weather screens can help to significantly reduce a building’s energy consumption, a key objective of voluntary sustainable design systems and codes worldwide. Weather screens include traditional sunscreens and more complex systems that can shield fenestrations from buffeting winter wind.
A variety of technologies are being used including louvers, woven mesh, perforated screens and green (plant) screens. They may be controlled by a computer, actively changing with varying conditions, or remain passively fixed.
Weather screens are often difficult to clean and maintain, making stainless steel a logical material choice for durable screens in more corrosive environments with coastal or deicing salt or pollution.
COMFEN (below) is an exceptional free resource for determining the possible energy savings associated with fenestration design modifications.

COMFEN is free downloadable software developed by the US government’s Lawrence Berkeley National Laboratory to allow designers to compare design choices so that fenestration can be optimized for maximum energy savings. The newest version, COMFEN 5 Beta, is based on US and international research and analyses of existing building performance and adds the ability to evaluate the impact of sunscreens.
The simple user interface makes it possible to compare the effect of varying key fenestration variables on energy consumption, peak energy demand, and thermal and visual comfort. The sophisticated analyses of the simulations are presented in graphical and tabular format. This flexible fenestration façade design system allows one or more zone modules with different design variables.

|What is IMOA?|
IMOA (International Molybdenum Association) is a non-profit industry association, which provides technical information to assist with successful specification of molybdenum-containing materials. Molybdenum is an element. When it is added to stainless steel, molybdenum increases its resistance to corrosion caused by deicing salts, coastal atmosphere and pollution.
