How Renewable Energy Technologies Amplify Buildings

By Energy CIO Insights | Tuesday, November 24, 2020

Photovoltaics are apt for buildings where they can reside on the unused rooftop area. Instead, they can also use the car parking space, where along with producing energy, they offer protection to cars and individuals from rain and sun.

FREMONT, CA: An exciting prospect for managing building energy needs lies in incorporating renewable energy resources into the built environment. Numerous renewable technologies that are commercially available today can entirely cover the consumption needs of buildings. These renewable technologies are variable, intermittent energy producers consisting primarily of Photovoltaic (PV) and wind turbine systems. Below are numerous ways to obtain net-zero energy in buildings.

Solar or Photovoltaic

PV is a chief renewable energy technology for buildings. PV energy production has quite a few benefits:

• Solar energy is limitless and available globally.

• It does not release Greenhouse Gases (GHG) or other pollutants during operation.

• PV systems need little maintenance.

• PV panels are silent.

• To make the tool even more engaging, the price of PV systems has significantly reduced in recent years, and the technologies also have become more competitive.

PVs are apt for buildings where they can reside on the unused rooftop area. Instead, they can also use the car parking space, where along with producing energy, they offer protection to cars and individuals from rain and sun. Another option for new PV integrations is to install them into the building architecture in what has become known as Building Integrated Photovoltaics (BIPV).

Combined heat and power (CHP)

Combined Heat and Power (CHP) or co-generation, is an energy production system producing heat and electricity from a single primary source. This technology is suitable for buildings or complexes of buildings (a campus) where it answers the demand for heat and generates electricity. As a demonstrated energy-efficient technology, CHP raises primary energy utilization and decreases greenhouse gas emissions.

Wind Turbines

Wind turbines are one more fast-growing renewable energy technology. Regardless of their vast energy potential, not many wind turbines are found on building roofs or car parks. And when they are, they characteristically are categorized by a small production capacity, usually not exceeding 10kW.

Because wind turbines are designed to be competent in an environment characterized by uniform and relatively continual wind flow, they often are located on hills, open plains, close to the sea, or offshore, in a group of wind turbines forming a wind farm.
