BASIX Requirements for New Homes

If you are planning to build a new home, you are going to hear many new unfamiliar terms, one such term is BASIX!. BASIX is “Building sustainability index” that helps to determine whether your home or building meets the government's sustainability target or not. Besides being a mandatory requirement a good score on BASIX ensures that your home or building is going to be built to a minimum energy standard and will be ecofriendly as well.

BASIX Consultants like us will help your house designs meet the BASIX targets.

“BASIX index” addresses the three attributes of “ecologically sustainable design” principles. The “Thermal”, “Energy” and “Water”.

Every home needs to be designed to conserve energy, water and be thermally efficient.
