Climate Change and the Need for Passive Solutions

As the effects of climate change continue to intensify, UK homes are becoming too hot.

Overheating from the sun is commonplace and making rooms uncomfortable. This problem will only get worse over time, making it necessary to find passive solutions to address it. As temperatures continue to rise due to climate change, overheating in homes has become a common problem.

The traditional solution to this problem has been air conditioning, but this is not always a viable or eco-friendly option. Passive solutions like Koolshade provide an alternative that is both effective and environmentally friendly.

Introducing Koolshade

Koolshade is a passive alternative to air conditioning that uses no energy. As an external solar shading remedy, it stops the sun's heat before it even gets into a building. It is a superior solution to solar glass, solar film, and other types of shading.

How Koolshade Works

Koolshade works by stopping the sun's heat with micro louvres, preventing it from entering and heating up the interior. This is achieved through the use of specially designed external shading fabric that is installed on the building's glazing.

The Eco-Friendly Solution

Koolshade is an eco-friendly solution that helps to reduce the carbon footprint of a building. By using no energy and reducing the need for air conditioning, it can help to lower greenhouse gas emissions and combat climate change.

  • Stops the sun's heat before it even enters the building

  • Uses no energy, making it an eco-friendly solution

  • More effective than other types of shading like solar glass and solar film

Instantly removes the Sun's heat but not it's light.

Koolshade is perfect for highly glazed structures, like conservatories and spaces like garden rooms.

  • It reduces the need for mechanical cooling like air-conditioning by over 68%

  • Makes spaces usable all year round 

  • Maintains contact with the outside world

Koolshade® stops overheating. Instantly.
Hurricane and fire-proof.


External Shading: The Best Solution

Stopping the sun's heat before it reaches inside

External shading is the most effective solution to prevent overheating in modular buildings. By shading the exterior of the building, heat gain can be reduced by up to 80%. This is because external shading blocks the sun's rays before they can penetrate the building, reducing the amount of heat that is absorbed.

Not only is external shading effective, it is also a cost-effective solution. Compared to other cooling methods such as air conditioning, external shading requires less energy and maintenance costs are lower. Additionally, external shading can improve the aesthetic appeal of the building by adding an architectural feature that can enhance its overall design.

Landscaping can also be used as a form of external shading. Trees and other vegetation can provide shade and help cool the surrounding air. Green roofs and walls can also be used to reduce heat gain and improve insulation. However, it is important to choose plants that are appropriate for the local climate and will not require excessive watering or maintenance.

How it works

How does MicroLouvre Koolshade® work?

MicroLouvre Koolshade® invisibly neutralises solar heat gain and glare before they even reach the window. MicroLouvre Koolshade® uniquely works non-stop providing dynamic g-value (heat blocking) performance to continually dissipate the sun’s heat and energy into the atmosphere but not blocking vision out, natural daylight or natural ventilation; solar shading using our products is efficient and effective.

Certified in efficiency and efficacy

Building Research Establishment (BRE) wind tunnel tested MicroLouvre Koolshade® screens from different angles and proved it to be indestructible at winds exceeding 100mph/160 kph/46 metres per second.

The Berkeley Lab included MicroLouvre Koolshade® in a major research project for PG&E. With MicroLouvre Koolshade®, daily cooling loads were reduced by 68% on sunny days when compared with dual pane, high performance solar control glass with an internal blind.

The IFC Group have confirmed MicroLouvre Koolshade® to be A1/A2-s1,d0 : BS EN 13501 Fire Rating, making it one of very few passive and dynamic external sun and solar heat gain blocking systems compliant for use on high rise buildings.

When tested at Fraunhofer, results confirmed MicroLouvre® as the most comprehensive solution for Thermal and Visual Comfort in one system.

Smartlouvre Technology Limited is an ISO: 9001 2015 Accredited Quality Management company.

MicroLouvre Koolshade® has been extensively modelled using computational fluid dynamics (CFD) in SimScale.
