The Retrofit Navigator (WHERbot) is a Web-based software tool designed for builders merchants, construction companies, and training providers. WHERbot allows a customer’s staff such as salespeople and construction advisors (through their intranet) and their own customers such as independent builders, architects, and homeowners (through their website) to learn everything they need to know about the new world of Whole House Eco-Retrofit (WHER).

Users ask WHERbot questions in ordinary language and it provides answers from a verified collection of authoritative documents, providing links inside each answer to relevant paragraphs and images. Customers can also promote their catalogues and price lists by adding them to this collection of documents. An expert team ensures that WHERbot continues to offer only verified, reliable information by curating customer-provided documents for relevance and accuracy.

Shown below are an illustration of how WHERbot works together with example questions from different types of user.
