Using the ALF tool

There are many approaches you can take to improve the thermal design of a house.
Use the calculation results to improve a house's heating energy efficiency.
It is a straightforward process to identify and amend weaknesses in a design and make changes to optimise thermal performance.
ALF can be used to assess existing houses and improve their thermal performance, but some adjustments may be necessary.
You can share projects with other ALF users.
