How efficient are Solar Energy Technologies for Buildings

 

Solar energy for buildingsSolar energy as a ‘green energy’ has been gaining amazing popularity in the last few decades. The use is amplified in recent times as more numbers of homes, offices, and industrial units are opting for this ‘clean energy’.

The popularity of this ‘photovoltaic energy’ has increased considerably over the past year. Globally, 75 GW of Solar Energy was added to reach a new high – 303 GW. The technology related to it along with attention towards it concerning the traditional sources (coal and oil) is also growing. Since 2012, this energy sub-sector is receiving double the amount of investment which is quite gratifying. “Till now we looked down for energy…but from now on, we have to look at the sky”

3 Types of Solar Energy Technologies

Currently, solar energy is being harnessed using three primary technologies. Which are:

  1. Photovoltaic (PV) – directly convert light to electricity;
  2. Concentrating solar power (CSP) – heat is being used from the sun (thermal energy) to drive electric turbines, utility-scale, and
  3. Solar heating and cooling (SHC) systems – accumulate thermal energy to supply hot water and air heating and/ or conditioning.

6 Reasons to use Solar Energy Technologies for Buildings

Solar energy is used in a wide variety of devices….from a calculator to cooking and from agri-tech to space-tech. But over a few years, it is being used in buildings in a bigger way. There are several reasons behind buildings are opting for solar sources in a greater way which are given below.  

  • Increasing energy consumption
  • Environmental consciousness
  • Global climate change
  • CSR implication/ advantage for Corporate buildings
  • Attraction towards cleanest, renewable energy
  • High social value and an increase in the value of the property

Why Buildings are Going Solar

Solar energy is freely available, clean, renewable energy source. The per capita energy consumption is going at an alarmingly high rate. The price of energy is also seeing new high figures.  

Buildings are now constructed keeping energy efficiency in mind. The aim is to minimize energy consumption and use alternative solar energy which has multiple benefits.

There are four aspects of energy efficiency in a building where technology can play a key role. Which are:

  1. Before the actual construction – zero energy passive building design.
  2. During the Construction – the usage of low energy building materials.
  3. Energy-efficient equipment – To make operational energy requirement low.
  4. Integration with other applications – lastly integration of renewable energy technologies for various applications.

7 Advantages of Using Solar Power in Buildings  

Solar Energy for building

  • Limitless Resource: Solar energy is renewable energy that never ends its supply.
  • Low environmental impact: Depending on the scale of the system installed – from distributed rooftop PV arrays to large utilities – solar technologies can produce lower environmental pollution.

 

  • Energy Independence: It makes Buildings energy independent and puts less pressure on natural sources of energy.
  • Multipurpose: It can be used in various ways and for multiple applications.
  • Ability for Additions: You can expand your PV systems effortlessly as they are modular.
  • Portable: Can be transported easily.
  • Post-Installation is Zero: Once the infrastructure has been installed no cost will be there after that (except changing inverter and batteries).

 

3 Ways Solar Powered Buildings are efficient

    1. Solar Powered Buildings improve the Heating & Cooling System’s efficiency by 30 percent by proper installation of a new HVAC system. Operating cost of a highly-efficient solar water heater can be reduced by 90% in Solar Powered Energy Efficient Buildings.
    2. When you use Low-Emissivity (Low-e) Window Glazing, it helps in reduces the space cooling need by approximately 40 percent. A light-colour roof reduces a roof’s temperature as it absorbs less than 50 percent of the solar energy.
    3. When Energy Efficient Lights and Energy Efficient Appliances are used, a Solar Building can reduce the energy use by 20-30%. With the continued emergence of construction technology innovations, it is becoming easier to achieve greater energy efficiency in buildings.

Conclusion

Solar Powered Buildings are quite efficient in preserving energy in various ways. By using the latest Solar Energy Technologies buildings can save around 30-40% on their energy use. You can also become a net-zero Energy Building owners when you create more energy than you utilize. Undoubtedly, Solar Powered Buildings with proper use of technology are more efficient in energy consumption.
