Top 5 green technologies in the construction sector



Green technology is one of the fastest growing initiatives in the construction sector. The true definition of the term ‘Green Technology’ is up for debate amongst professionals but in its simplest form, green tech involves producing new buildings that use one or more environmentally friendly solutions. Using green technologies has truly set the standard for construction companies all over the world. At buildy, we’re always keen to get to grips with how our users take advantage of resource efficient and responsible processes. So, we thought we’d compile a list of some of the most trending technologies. Here’s a rundown of the top 5 trends in green tech:

  1. Cool Roofs

Cool roofs are solutions that aim to reflect heat and sunlight away, helping to keep residential homes and buildings at room temperatures all year round. When done right, cool roofs can reduce temperatures by up to 50 degrees Celsius in the summer (sadly, not a huge problem for residents of the UK!). Cool roofs make use of reflective paints and tiles that absorb less heat, minimising the need for air conditioning and therefore decreasing greenhouse gas emissions.

  1. Green insulation

Contrary to popular belief, insulating a house doesn’t need to involve expensive and waste-heavy materials. Green insulation completely removes the need for high-end finishes made from non-renewable materials. Making use of old materials like denim, newspaper and even cotton essentially uses recycled productions to insulate the home. What’s more, removing the need for fibreglass means no more shards stuck in workers skin – not at all pleasant!

  1. Rammed earth brick

Rammed earth has been around for thousands of years. In fact, large sections of the great wall of China have been made using rammed earth. Today, the process of using rammed earth isn’t that different from how it was made all those years ago. A moist mixture of earth and hard substances, like clay or gravel, are combined with a stabilizing element like concrete and compressed to form dense, hard walls. After forming, rammed earth must cure for months to completely harden. The density of rammed earth makes it an ideal material for regulating the temperature of a building. How’s that for smart?

  1. Smart Glass

Speaking of smart, Smart Glass is one of the fastest-growing technologies used today. Electronic smart glass works particularly in summer periods to block out the harsh heat of solar radiation. Smart glass uses tiny electric signals to slightly charge the windows to change the amount of solar radiation it reflects. With this technology, homes and commercial buildings can save a lot on heating, ventilating, and air conditioning costs. This type of glass is still being perfected, but expect to see more of it in the coming years as competing developers bring this smart energy-saving technology to the market.

  1. Smart appliances

Staying with the same theme, today’s modern appliances are becoming smarter than ever. The latest units in the market, especially those used in the kitchen, are designed to save energy and simplify our lives. For example, LG’s SmartGrid refrigerators, dishwashers and washing machines all tie into a smart meter to be as energy efficient as possible. Smart meters are essentially electrical meters that gather real-time data which can be used to determine energy rates and automatically run when electricity rates are at their lowest. Clever, right?
