Scope
Overview
Phius Certified Builder (CPHB) is a program that trains and certifies builders in passive house construction techniques, promoting energy-efficient building practices. The program was created by Phius, an organization founded in 2003, aiming to make buildings more sustainable and energy-efficient.
The CPHB program covers construction methods that significantly reduce energy usage in buildings, focusing on aspects like insulation, airtightness, and ventilation. Builders who complete the program can build homes and buildings that consume up to 90% less energy for heating and cooling compared to typical buildings.
CPHB certification is beneficial not only for individual builders but also for organizations, including non-profits, that aim to construct eco-friendly and energy-efficient buildings. Phius collaborates with various industry partners and clients to ensure widespread adoption of these practices. Important clients include government agencies, educational institutions, and housing organizations dedicated to sustainability.
