Engaging a qualified certifier for BASIX certificates offers several significant benefits:
The BASIX assessment process begins with an initial consultation between the certifier and the homeowner, or architect. During this meeting, the certifier gathers preliminary information about the project, including its scope, design, and specific sustainability goals. This consultation helps the certifier understand the unique aspects of the project and identify any potential challenges or areas of concern. It also provides an opportunity for the certifier to explain the BASIX requirements and the assessment process in detail, ensuring that all parties are on the same page from the outset.
Following the initial consultation, the certifier collects detailed data on various aspects of the building. This includes information on the building's location, orientation, size, construction type, window size and type, landscaping, and the appliances to be used within the building. The certifier uses specialised software tools to model the building's energy performance. This data collection and analysis phase is critical identifying areas for improvement.
