How to have a net-zero energy home?
Updated: Feb 25
One the ambitions at The Hamlet Theur is to have a community of net-zero homes. A net-zero energy home is just like any other ordinary home, but a lot better. Here the building produces about the same energy as the energy consumed by the building. We have given different methods to be employed to achieve the title of net-zero energy home.
Solar panel installation
Solar energy is one of the most freely available energy sources. The conditions are even better in India where the country receives ample daylight most of the year. This results in producing extra electricity, which can then be sold to the local electricity board for the appropriate fixed rate. This is the best way to become a net-zero energy home. With some calculation about the cost of installation and benefit of free energy, one can easily decide the space to be allocated for the solar panel.
The Vaastu Shastra has many scientifically-backed texts which we nowadays see in practice. One should orient the house along the east-west axis to minimize exposure to rising and setting sunlight. Design of the living spaces should be altered so as to face cooler facades. Patios and decks must be placed on the north side in the shade of the building.
One must utilize exceptionally intelligent material. Here white metal material or white solid tile material is ideal. On the off chance that the house has an unconditioned storage room, brilliant boundary rooftop sheathing is prescribed.
One must use naturescaping to create natural shade for the house.
Each window ought to be concealed, regardless of whether with regular concealing, by window curtains of at least 3’, by being recessed in thick walls, by wide patios on the east and west, or by utilizing a mix of these methods.
Most of the windows should open to north or south. This will increase the cross-ventilation. Windows on the east and west ought to be limited since they are progressively presented to low points of the sun and lead to overheating more than windows on the north or south.
Securing air pockets
Secured air pockets help a lot in cooling the whole building. Such walls spill outside heat inside and increase the load on the air cooling system. These walls also permit dampness to enter the moulded space which in turn forces air cooler systems to work more diligently. In damp conditions, airborne water fumes from outside present a risk of heating the house and moulds that will be diminished via air fixing.
It is significant that the home's cooling and ventilation ducts are inside the home. In the event that ducts can't be set inside the living space, put them inside impermeable fixed and protected storage room.
Since dampness causes a home to feel more blazing and makes cooling increasingly costly, the accompanying techniques ought to be utilized to forestall it entering the home. We must make the home as water/air proof as conceivable to keep dampness out and introduce an appropriately measured Energy Recovery Ventilation (ERV) framework with vents in the restrooms, clothing and kitchen to remove dampness while keeping hold of the home's cool air. Take care to appropriately measure the home air cooling system, as a larger than usual system won't adequately remove water fume. For moist atmospheres consider introducing a dehumidifying heat pipe related to the air cooling system.
We hope you will want to include some if not all the options described here to make your house net-zero energy house. This will ultimately help our nation reduce our dependence on foreign currency to be spent on oil and coal.
At The Hamlet, Theur, we build the houses so as to lower the energy demands of the customers. We strive to build net-zero energy houses so as to lower or even earn money from the home designs. To know more, contact us.
