31 Aug 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
