Building Energy Services Consulting 

Single Family and Multi-Family

residential energy consulting

GDS Associates provides energy consulting services to owners, builders, property managers, code officials, architects and others in the building industry. Clients are provided with expert design consultation tailored to their needs, focusing on energy performance, comfort, resiliency and durability. We work with clients from design phases through construction completion providing simulated energy usage modeling, inspections and testing through the construction phases.  Our experts guide the development team through permitting, code compliance and building completion. 

GDS takes an integrated approach to the energy performance of a home. Using computerized building energy simulation modeling, we identify opportunities to strengthen the building’s energy performance, durability and safety. A building is a system of integrated components that should perform in harmony with each other.  We develop cost-effective design-alternatives and improvements to maximize efficiency value and minimize operation and maintenance costs.
