Energy saving Landscape Design

 

Energy saving and he cost of heating and cooling is one of the most significant expenses by any property owner. Using excessive energy indoors to maintain a comfortable temperature is wasteful, adds extra CO2 and other pollutants to the air, and puts pressure on national and regional energy resources.

With rising energy costs, people are looking for methods for energy saving.

The Rising Cost of Energy and the Need for Energy Saving.

The rising cost of energy is a significant issue for the people of Melbourne. The city is becoming hotter as a result of climate change and the urban heat island effect caused by materials such as concrete, brick, and bitumen that store heat from the sun, requiring them to use much energy to maintain their indoor temperature.

The urban heat island effect caused by materials such as concrete, brick, and bitumen keeps the CBD hotter by storing heat.  Smart landscape design can keep areas cooler and provide an energy saving.

Homeowners, commercial building owners, and public place owners are all searching for ways to save energy in their properties. Various methods can and should be used to reduce energy use. However, smart landscape design can and should make homes more energy efficient. Attractive and well-planned landscaping may do more than enhance the aesthetic appeal of a property; it can also help save money on energy bills.

Landscape Design for Energy Saving.

Well-placed trees, bushes, vines, and artificial materials may provide excellent shade and serve as a wind barrier, changing the environment that surrounds your property to limit heat gains in summer and heat losses in winter. Your property may be protected from winter winds and the summer heat by the presence of plants. Through smart energy saving landscape design, we can further enhance the energy saving of a 7-star energy-efficient home.

According to Fisher (2007), shade trees in Australian cities like Melbourne and Adelaide save about 30 kWh energy per tree, which means that Melbourne's 2.4 million shade trees save 72 million kWh energy per year, preventing 86,000 tons CO2 emissions per year from coal-powered electricity.

According to research, a good landscape design may change the temperature in and around your house by up to 12 degrees Celsius. In addition, a study revealed that a well-designed landscape results in energy savings and a return on investment in less than eight years. It has also been reported that strategic placement of trees in the landscape design may cut winter heating costs by up to 25 per cent and summer cooling costs by up to 50 per cent or more.

ROLE OF DECIDUOUS VINES IN ENERGY SAVING LANDSCAPE DESIGN

This article aims to increase the exposure of buildings to the winter sun, decrease exposure to the summer sun, and lower the surrounding air temperature during hot weather in Melbourne City. Following are a few ways to create an energy-efficient landscape design that can reduce our utility bills.

The Planting of deciduous trees for Energy Saving

Every day, urban trees offer a variety of advantages to all of us. They bring soothing shade, stop chilling winter winds, attract birds and other animals, filter the air, stop soil erosion, produce fruits, clean the water, and enhance the beauty of our homes and neighbourhoods. Planting the good trees in the proper locations conserves energy, decreases our electric costs, and helps in the battle against global warming.

In addition to enhancing the beauty of the environment, deciduous trees are very beneficial around the house, commercial buildings, and in public areas because they give cooling shade in the summer, which lowers your air conditioning expenses, and they allow the sunshine to enter in the winter, which reduces your gas heating costs.

Evergreen trees cannot provide this shadow contrast. Because of the deciduous trees, you may spend more time in your outdoor garden.

The priority in energy-saving landscape design is tree placement. Where would you want to grow trees and shrubs? And what are you hoping to achieve by increasing these trees and shrubs? The answers to these questions determine the project's significance and effectively describe what you aim to achieve.

Energy saving landscaping with the use of deciduous shade trees to the North and West.

Deciduous trees are excellent for windows facing north, northeast, and northwest. These trees are ideally placed in these positions because of their ability to be packed in the hottest months of the year and barren in the coldest months of the year. Allowing in winter light while shielding the home from the hottest summer rays in summer is the perfect energy saving situation.

It is best to avoid unshaded pavement to the north, east, and west, as hard surfaces reflect heat upwards through windows. Lawns and low ground covers are great options for such spaces if you can't avoid paving. Deciduous trees with good shade and a wide canopy can help if you already have a driveway.

East and west-oriented windows are difficult to protect from the severe summer heat because of the angle of the summer sun and its location higher in our sky. The covering of deciduous leaves to the ground on the eastern and western sides can prevent the summer light from reaching the walls or windows at low angles, but you will still need to invest in exterior shade systems. Vertical screening is the best option for blocking the sun at these angles.

It is more challenging to protect North-facing windows from the extreme summer sunlight. Planting deciduous trees near the home might provide much-needed shade, especially if your outdoor gathering takes place in this direction. Here are the most fantastic deciduous trees to plant in commercial landscape design to save energy or to employ in your home to build a 7-star energy-efficient house.

GINKGO BILOBA

Ginkgo biloba, often known as ginkgo, is a tree species native to China. It is a large and beautiful deciduous tree that grows slowly and lives for a long period.

This tree has an excellent shape and offers beautiful colour in the autumn. According to studies, the ginkgo tree might help urban areas to survive climate change by creating a huge amount of oxygen. Because of their summer shade, ginkgo trees are popular among landscapers.

Using 3D Landscape Design for Energy Saving

Using advanced 3D design tools, we can develop a landscape design plan to reduce energy usage in most landscape designs. The landscape design software allows us to check for the position of shadows for any given day of the year.

The position of the sun in the sky varies with the season. The tilt of the earth means the sun is much lower in Winter as you move further from the equator.

ENERGY SAVING WITH LIGHT COLOURED EXPOSED AGGREGATE CONCRETE FOR DRIVEWAYS

Dark coloured concrete can absorb heat from direct sunlight, store the heat and release it slowly and create thermal mass, which increases the temperature of your home, and it takes a lot of energy to lower that temperature. Changing colour is the easiest way to make exposed aggregate concrete driveways cool. Driveways having light colours will reflect more sunlight and absorb less heat. Fortunately, exposed aggregate concrete is available in many colours. So choose and install light colour concrete for driveways.
