Performance Warranties

Under Transition Zero, the focus is on providing a performance warranty for 30 years.  However, many building components are available for longer than 30 years with minimal extra cost and many heating systems have a lifetime of considerably less.

An Energiesprong performance warranty will provide a 30 year guarantee of energy and comfort factors
·    Set minimum component warranties of 5 yrs

·    Uphold component warranties that are longer than 5 yrs, e.g cytotec dosage. PV

·    Warranties assume that the required maintenance is carried out.

·    PV degradation and battery performance may challenge overall performance

·    So normally actual performance will be checked in year 2

·    Allow for more efficient component replacement, improving technologies
