Residential Energy Efficiency Assessments
SJH Drafting provides energy assessments for all new residential dwellings, duplexes and apartments using The NatHERS (Nationwide House Energy Rating Scheme). NatHERS is the most common way to show that a new home meets the minimum state and territory building energy efficiency requirements based on the National Construction Code (NCC).
It involves modelling your design using accredited software (FirstRate™). This advanced software analyses your building and assessors the heating and cooling loads required to keep your house at a comfortable temperature and provides you a star rating from 0-10 stars based on your design. In WA you are required to achieve a minimum energy star rating of 6 stars to achieve compliance.
By incorporating some simple Passive Design Principles into your home design, you can reduce your heating and cooling costs, improve the overall energy efficiency of your home and make it more comfortable space to live in and above all reduce the greenhouse gas emissions for the life span of you home.
Passive Design Principles relate to:
- Passive Solar Heating
- Passive Cooling
- Sealing of your home
- Thermal mass
- Type of building materials used
- Construction methods

Architectural Documentation is one of the key facets of the design process. The process of methodically developing construction types and materials and making them dimensionally correct to form a building detail that interacts with its surrounding elements provides the builder with a detailed record of how all aspects of the building will fit together to make up the building form. This helps the builder to estimate, plan and construct from and makes for a seamless building process.
