“Passive Solar heating systems are incorporated into the design of the home or addition and are typically part of a new home design or remodeling project. We have been designing solar, wind and biomass energy systems since 1973.”

 

Style is the synthesis of experience, innovation and design. Imagine a home designed around you, your family, and the way you live. You talk, we listen. Ideas, thoughts, issues, concerns, and costs, all of it gets considered in the design process. Out of that process, your home will emerge, a vivid, vital expression of who you are, giving your home a unique style you can call your own.

 
 

SDG has been a pioneer and innovator in green high performance homes for decades. We have developed numerous building and renewable energy products and technologies to maximize comfort and health while minimizing operating costs and environmental footprint. Our attention to detail results in homes that can be self-sufficient and completely independent of the electricity, water, and sewer grids.

 
 

SDG President John Spears has been designing and building healthy, energy-efficient, green, solar homes around the world for over 35 years with an emphasis on self-sufficient buildings and communities. He has designed sustainable communities in Mexico, South Africa, and China, including the Beijing Olympic Village. Over 6,000 of John Spears' Earth Homes™ have been built around the world, and he has consulted on numerous LEED projects.

Renewable Energy Systems Design

We can help you design a solar PV system for electricity generation or back up power. We can help you design active solar water heating and space heating systems. We specialize in Passive Solar Heating systems for homes. Passive Solar heating systems are incorporated into the design of the home or addition and are typically part of a new home design or remodeling project. We have designed wind power systems and combined wind and solar PV systems.

In developing countries we have designed bio energy systems that convert pig manure to methane gas for cooking and power generation at a village scale. We can help you qualify for State and Federal Tax incentives and also help you apply for grants where applicable.

We have been designing solar, wind and biomass energy systems since 1973.
