Published on

Educational seminar: Remodeling Towards a Green and Healthy Home, What is building you dream green home has to wait a while? In the meantime, there are plenty of things you can do to green up what youre already got. Green and sustainable renovations, whether large or small, can help save you energy and resources. Plus, taking some simple steps towards creating a healthy home can go a long way in reducing your body burden of toxic, synthetic chemicals found in many building materials and conventional cleaning supplies. An understanding of our personal home environmental can help us make informed decisions about environmentally friendly building materials and best practices in construction. An awareness of our human ecology can reduce our body burden of environmental toxins, while also reducing our impact on the earths natural resources.

This presentation and Q & A will cover the nuts and bolts of green renovations, from both a builders perspective, and also that of a healthy home consultant. Whether youre a ahomeowner or a renter, the green strategies that will be offered in this clinic will help you synthesize the wealth of information surrounding green residential renovations.

The presenters are Laura Catanzaro from Holistic Design and Space Planning and Dan Glickman from Sustainable Construction Services, Inc.

  22. 22. Evaporative cooling with fans vs. using AC From Bruce Harley’s Insulate and Weatherize Renovating your mind…  Planning and building for your lifestyle could have the greatest impact on your “greenness”.  Consider “mundane” innovations over ecological “bells and whistles”.  Hire a contractor who is experienced with green construction—go with his/her strengths and biases—and “push the envelope” together.  Green isn’t just a collection of strategies to be randomly applied. Use principles and processes, not just products, practically and imaginatively.  Choose opportunities appropriate to your situation. September 2008 Green Round Table
