Affordable Green Building Series Videos

DVD_COSCimageCOSC's Affordable Green Building Series videos provide an overview of best practices throughout each construction phase of building a durable, healthy, energy efficient, cost effective and environmentally sound home.

The segments, applicable to homeowners, building professionals, government agencies and others, illustrate that sustainable building is a very viable and achievable way to improve the quality of life in your local community. In leading a collaborative effort with multiple partners, COSC's goal is to promote a platform for consistent, comprehensive, sustainable building trainings where local experts are empowered and national standards are supported.

This educational video series was produced during COSC's Affordable Green Building Training workshops developed for the West Des Moines Affordable Green Demonstration Home - a community project lead by the City of West Des Moines in partnership with HOME Inc and Center on Sustainable Communities (COSC). COSC's series of homeowner and building professional workshops as well as the video production was made possible by the City of West Des Moines, Iowa Department of Economic Development, U.S. Department of Housing and Urban Development and many others.

GREEN BUILDING OVERVIEW

Linda Schemmel of City of West Des Moines and Bill McAnally of McAnally Consulting introduces us to the West Des Moines Affordable Green Demonstration Home project and COSC's educational curriculum.

What is Green Building? It is a "Whole Systems" approach for designing and constructing buildings that:

  • are integrated into the wider site and community
  • consumes less energy and water
  • are durable and easier to maintain
  • use resource efficient techniques and materials
  • are healthier, safer and more comfortable

We learn about the importance of the project's pre-planning stages, charrette meetings, benchmarking, green building goals, cost-saving opportunities, stakeholder buy-in, educational approaches and more.

FOUNDATIONS, BASEMENTS & RADON MITIGATION

Foundations are one of the most important aspects of green construction. Topics covered in this chapter include:
