When it comes to energy efficiency, orientation is crucial. Buildings with windows should face south to get maximum sunlight exposure. The sun rises in east and sets in west, so orienting buildings towards the south will maximize sunlight’s energy.
To Maximize Energy Efficiency, Orientate a House
A house’s orientation will affect its comfort and energy consumption. It is important that you consider the local climate as well as the prevailing winds when choosing the right orientation. The best orientation is one that maximizes the northern exposure and minimizes the exposure to the east and west, while still allowing cool breezes to penetrate the interior.
Proper orientation is key to maximizing energy efficiency. In hot climates, the east and west elevations are more exposed to solar radiation. The interior elevations are more spacious and compact, making it appear larger.
The most suitable orientation for a U-shaped house will depend on its solar exposure and its RC. The house’s most protected sides should contain the main living areas. A house oriented to the south in the Northern hemisphere is generally more efficient than one oriented to the north in the southern hemisphere. It is important to protect the main rooms against wind and cold. A buffer zone is needed to separate the main rooms and the exterior.
The study used MATLAB software in order to simulate the energy efficiency for a U-shaped structure using a parametric model. These simulations were made with data from buildings of various layouts. It also used DesignBuilder energy simulation software, which was used to model the energy use of different layouts.
Abanda (and Byer) also used BIM software to calculate the effect of different orientations on energy use. Green Building Studio, an energy simulation program of excellence, converted the model into numerical values. The study also considered lighting energy needs.
The house’s shape also plays a major role in its energy efficiency. A rectangular-shaped house is less likely lose or gain heat in summer because it has fewer walls. A smaller design also reduces the roof area and footprint. This makes a home more efficient in winter and cooler in summer.
Orientation of A House to Minimize Wind Exposure
The key to energy efficiency is the orientation of a house to minimize wind exposure. It is important that the living areas of a house are located on the southern end. This is because they will receive more sunlight in the winter months and cooler temperatures in the summer. South-facing patios are also recommended, as they will receive more direct sunlight and can be used more often. It is a good idea to place parts of the house that aren’t used often in the north. This will act as a buffer from cold winter winds.
The prevailing winds in an area will determine the best orientation for a house. It is crucial to choose the right orientation, especially if you live near a hot climate. A house facing west or east will receive more solar heat. That is why the lowest elevations should face east and west.
Lower energy bills can be obtained by orienting a home to minimize wind exposure. In warm climates, orienting the house to the east or west of the prevailing wind direction will maximise solar gains during the day. In cooler climates, orienting the house to the south will allow the house to capture the cooling breeze. It is important that you remember that wind orientation may affect other aspects of the house’s design.
