Affordable Housing: Use Local Underutilized Materials

Local Materials

Design Performance Objective

Wall Systems - Structure
The wall section illustrates the use of locally produced straw bales and lumber as well as flyash and windows produced regionally.

Student: Mark Weagel

This particular studio project was located in the host institution's own climate zone, cool/temperate. The principles of the studio could be applied to any climate zone.

Software/Tools:

HEED and Opaque web

Fall 2006 McCall Field Campus Studio

Program Statement
Use local and underutilized materials to reduce cost and carbon emissions.

This project responds to NAAB Student Performance Criteria

#19: Environmental Systems
Understanding of the basic principles and appropriate application and performance of environmental systems, including acoustical, lighting, and climate modification systems, and energy use, integrated with the building envelope

#21: Building Envelope Systems
Understanding of the basic principles and appropriate application and performance of building envelope materials and assemblies

#28: Comprehensive Design
Ability to produce a comprehensive architectural project based on a building program and site that includes development of programmed spaces demonstrating an understanding of structural and environmental systems, building envelope systems, life-safety provisions, wall sections and building assemblies and the principles of sustainability

Investigative Strategy

Research availability of local underutilized materials. Mark Weagel’s wall section shows the use of straw bales from nearby farming operations, glu-lam beams from a regional manufacturer in Boise (ID), windows from a factory in Bend (OR), flyash from Montans coal-fired power plants (ugh!) and ponderosa pine from the local mill. The wall is a super-insulated composition that will minimize energy used for heating, especially since the building features sufficient thermal mass and a wide southern aperture.

Evaluation Process

Opaque software from UCLA was used to model the thermal properties of the wall, while HEED was used to model the thermal performance of the building.

Evaluative Criteria

A successful project uses far more local materials than exotic ones and exploits at least one under-used material. The materials are combined to create a high-performance wall as demonstrated by the HEED and Opaque analyses.

Cautions - Possible Confusions

Research is necessary to determine the availabilty and suitability of local and regional products, recycled components, and under-used materials.
