Designing a near zero energy building (NZEB) will require the façade consultant/designer to calculate the building envelope performance. Does the energy efficient building incorporate a climate responsive façade using a dynamic façade (controllable façade/intelligent façade) or do they seek a passive solar protection strategy?

The thermal modelling bureau/consultant will consider smart building control as smart control can produce a more sustainable building giving environmental sustainability. A load reduction strategy, solar cooling load reduction or building cooling optimisation can produce building maintenance cost reduction, greenhouse gas reduction, all with correct solar shading strategy reducing internal heat gain.

Energy & environmental management considerations of the glazed architectural design such as a double skin façade done well can boost office productivity with a great indoor climate but ignored can lead to sick building syndrome.

Considerations such as retrofitting versus new building, design integrity of the façade whether for the residential market, incorporating smart house home automation with home video equipment intelligent drapery, sheer net curtains are all strategy considerations. Which shade determines visible transmittance or window luminance. The science of solar shading is the same if it is for a multi-story office tower or a domestic conservatory. Which window coverings, how deployed? A panel track system, a velum, a roman shade or a roller-screen?

The same anti-glare office blinds can be used as the anti-glare roller blinds for air traffic control towers. Anti-glare sunscreen not best for ATCT blinds where best anti-glare transparent solar blinds are made from materials like anti-glare window film. Anti-glare window blinds can also be anti-heat blinds using fabric such as Mermet MSU M Screen Ultimetal – use of this metallised screen fabric internally with its low emissivity coat gives great thermal performance as if it is a magic screen – a magic screen one way blind, only seeing through it one way depending on where the light balance is. Metallised screen fabric external use is rare, but Mermet Satine 5500 Metal is a waterproof external fabric and has the aesthetic appearance of metal which can be so important for the design integrity of the façade.

Anti-glare transparent solar film blinds as used for aviation system blinds or aviation blinds can also be used in anti-glare marine applications or as anti-glare blinds for office.

Anti-glare transparent solar screen blinds and anti-glare screen blinds can be used for aviation system blinds or aviation shading they can also perform for anti-heating performance.

Acoustically absorbent fabrics are good for acoustic blinds possibly better than acoustic curtains where their acoustically absorbing properties work well. Acoustic fabrics or acoustically transparent fabrics can be used for auditorium blinds or architectural fabrics, producing acoustic screens depending on the choice of acoustic blind fabrics. Aluminium blinds or anti-fire blinds cannot be acoustically transparent nor to supply architectural solar power.

Blackout fabric for external needs to be such as the Mermet Satine 21154, the Blackout Satine 21154 having a strong fibre glass core.

Blackout fabrics internally such as the blackout Flocke 11201 or the Kibo 8500 still have the fibre glass core unlike the blackout Karellis 11301. Whichever blackout material is chosen for the blackout roller blinds or the blackout screens BS 476 Pt 6 Class 0 is a great fire rating to have as both the Kibo 8500 and Flocke 11201 do.

Whichever blackout blind material the blind maker choses from the blind fabrics for his blackout system they may wish to make the blind controls automatic. Blackout window blinds may also be blinds for energy saving, blinds for heat control, even blinds for eye comfort. A blinds energy efficiency may consider how cold air is heating the world, or how to improve comfort levels with shading they may include hospital blinds, exterior blinds, including external blackout blinds. These can double as insulating blinds by using insulating fabrics – the same could be achieved with internal blackout blinds using Karellis 11301. In determining what may be classified as an energy efficiency blind or making an energy saving with shading you need consider the properties for heat control blinds, be they heat control roller blinds or heat reflective blinds for windows giving heat protection and energy savings.
