Developing an Energy Efficient, Solar-Heated Greenhouse in Maryland

The lack of year-round availability of locally grown food and food processing infrastructure are the greatest barriers to increasing the consumption of local food in western Maryland. If an economical, year-round or extended food production system could be developed, it would lead to increased demand for locally produced food, which in turn would foster the growth of needed processing infrastructure.

This project sought to encourage season extension by investigating 1) the effectiveness of energy efficient greenhouse design, and 2) the ability of water-heating solar panels to heat a greenhouse as a propane alternative.

The greenhouse was built on a farm in USDA Plant Hardiness Zone 5b.
