Did You Know?

You can increase the value of your next remodeling project by including energy efficiency improvements. Learn how with Energy Efficiency Improvements for Remodeling Projects.

Site work is the placement of products, materials, utilities and accessories that go into the land around the house, or on the site that the house is built on. Natural filtration occurs when permeable pavement can be used for driveways or walkways, while xeriscapes offer a viable alternative for attractive exterior space planning without consuming dwindling water resources.

PATH Technology Inventory Review This report describes the process and results of a short-term activity initiated by the Partnership for Advancing Technology in Housing (PATH) to review and identify technologies in the 162-item PATH Technology Inventory that should be high-priority candidates for a concerted PATH technology transfer or diffusion effort.
TechPractices: Grove at Patuxent Woods, Patuxent City, MD In this project for seven affordable houses, it was possible to concentrate shared wastewater treatment systems in areas of the site with adequate soil conditions, allowing four houses to route their septic to a fifth lot, while two other houses shared a septic field.
