Green Building Foundation
Green Foundation Resource
A well-planned foundation can make a substantial contribution to controlling heat and cooling costs while eliminating potential moisture and mold problems. There are many different types of foundations to choose from, depending on climate, soils condition, water table and other factors.
See Chapter 4 on Foundations in the Green from the Ground Up book for more details or contact us about training .
Heat is lost through foundation walls, crawl spaces and concrete slabs. Foundations should always be insulated, preferably on the outside to reduce the risk of condensation and make the mass of concrete or block walls part of the conditioned space. An insulated foundation becomes part of the house's thermal envelope, contributing to energy conservation and creating a more comfortable environment.Insulating a Basement on the Inside
Although exterior insulation offers more advantages, basements can be insulated from the inside, too. The key is controlling the movement of moisture and mold-inducing condensation as warm air migrates to a cooler surface.Green Foundation Transition Guide
Some tips and best practices to get started.
Build forms from plywood or aluminum
Initial costs are higher, but they save the trouble and expense of replacing forms made from dimensional lumber
Wood forms made from 2x12’s can only be used a few times and are usually too soiled to be recycled
Reuse forms as much as possibleModular forms are made for most foundation applications Keep as much material out of the landfill as possible can reduce landfill costs Clean and stack used forms after use and reuse them on another project
Use insulated concrete forms
Combine insulation and concrete to form one wall
Polystyrene blocks are stacked to create a foundation wall and concrete is poured into the void for rigidly
Save on both concrete and labor costs
Many companies make ICFs. There are blocks that are made from recycled woodchips and mineral wool. Most are made from polystyrene
Install a perimeter drain at the base of a foundation wall
A perimeter drain gathers water that might otherwise damage the foundation wall, and channels it away from the foundation.
A perforated pipe wrapped in landscaping felt and placed in a bed of crushed rock located around the footing of the foundation
Insulate foundation walls and slabs with rigid foam
Use at least 2&rdq...
