ZeroEnergy Design (ZED) designs green and healthy homes. One of the services they offer is the Renovation Recommendations Report, which gives suggestions on how to make indoor air healthy, conserve water, choose the best materials, insulation and heating systems, among others. The customized report is available within 7 days from your order for $899. This sounds like a big expense, but for sound advice from experts, this can be cost-saving in the long run. Recommendations are categorized into Energy, Water, Air and Materials. You only need to give information about your house, renovation goals, budget, behaviors and preferences, and ZED will do the rest.
