Abstract: Information contained in the building/property reports and assessments are long, terminology is difficult to understand and content is hard to access or manipulate. Traditional approaches to building inspection and assessment of value are insufficient and do not encompass all factors now relevant. These additional factors include measurements, testing and inspection of a building's energy efficiency and environmental health/safety as it relates to inhabitants of the property. This new information, plus the traditional inspection information and appraisal data will provide a complete valuation of a home or building and its overall impact on inhabitants. All data can be collected, assigned numerical values, and a weighted scoring system can be developed that is accurate, understandable and accessible. The information, scores and indexes can be stored, managed, presented and shared in a fast, unique and relevant manner for stakeholders to see and use to benefit themselves and the marketplace.
