Green Building

 

A blooming industry, green building is rising with greater public demand, legislative focus, and code and standard mandates. With programs like Leadership in Energy and Environmental Design (LEED) becoming more popular, contractors are finding new building processes and technologies to be more efficient and environmentally minded. The below articles dive into alternative energies, energy efficiency, the smart grid, and more and include editorial from our annual special issue on the subject.

The community solar market barely existed just a few years ago, but now the concept that allows even renters to invest in their own photovoltaic (PV) panels is going gangbusters in a number of states.

Around the country, solar photovoltaic installations are sprouting on residences and commercial buildings. If Doug Neidich has his way, we’ll see many more of these, but of a different variety.

Green building trends have affected nearly every sector of the construction and renovation market, and schools and universities are part of it.

Imagine an energy source buried thousands of feet below us that can best be accessed by sending highly pressurized fluid to open fissures in underground rock.

Here Comes the Sun

Solar-power cells, also known as photovoltaics (PV), are semiconductors that convert sunlight directly to direct current (DC) electric power. “The sun’s light dislodges free electrons in each cell on the solar panel and collects them on conductors to create a volt.

In the Spotlight

According to the U.S. Environmental Protection Agency’s (EPA) Energy Star program, lighting consumes 25 to 40 percent of the energy used in commercial buildings and is a primary source of waste heat.

Photovoltaic Finish

The Leadership in Energy and Environmental Design (LEED) recognizes the contribution that photovoltaics (PV) make to the sustainability and efficiency of a building project through its Green Building Rating System for New Construction & Major Renovations (LEED-NC Version 2.1).

PV and Energy Codes

Energy codes establish the minimum requirements for the performance of new buildings. States have typically adopted either the ASHRAE/IESNA Standard 90.1 or the International Energy Conservation Code (IECC) as their energy code for commercial buildings.

Sunspots

The surface of the earth receives a tremendous amount of energy from the sun. It is estimated that the amount of solar energy that strikes the earth's surface daily is greater than the amount of energy used worldwide in 25 years.
