Net-Zero Energy & Renewables
Net-zero energy use is the ability of a building to supply its own energy over the course of a year by using renewables (typically onsite renewables, though some definitions include offsite procurement).
Alternative energy sources like photovoltaics are becoming more affordable, increasing the possibility that a building project can achieve net-zero energy. And as more buildings use renewables along with storage technologies, there are opportunities to harmonize with the grid and use more renewable energy from there as well.

In the Pipeline: District Energy and Green Building
Feature
Very common in northern Europe, district energy systems use a network of buried, insulated pipes to distribute centrally produced steam, hot water, or chilled water to heat or cool multiple buildings. These systems can make use of waste heat from power generation (combined heat and power) or renewable fuel sources to help reduce the environmental impacts of buildings and communities.
