▁In ▁all ▁countries , ▁H ERS ▁show ▁variations ▁in ▁object ives , ▁assess ment ▁method ologies ▁& ▁measurement ▁criteria ▁but ▁after ▁all ▁this ▁variation , ▁the ▁goal ▁of ▁all ▁H ERS ▁is ▁approximately ▁same ▁and ▁these ▁generate ▁the ▁output ▁in ▁same ▁way . ▁ ▁H ERS ▁outputs ▁Basically ▁H ERS ▁generates ▁three ▁types ▁of ▁outputs ▁▁ 1 ▁R ating ▁score . ▁▁ 2 ▁Energy ▁use / Cost ▁prediction . ▁▁ 3 ▁Re comm end ations . ▁▁▁▁ ▁R ating ▁Sc ores : ▁The ▁energy ▁performance ▁rating ▁is ▁a ▁type ▁of ▁energy ▁assess ment ▁how ▁efficiently ▁the ▁buildings ▁use ▁energy , ▁relative ▁to ▁similar ▁buildings . ▁The ▁performance ▁scores ▁use ▁generally ▁a ▁scale ▁r anging ▁from ▁ 0 ▁to ▁ 1 0 0 ▁or ▁ 1 ▁to ▁ 5 ▁stars . ▁The ▁value ▁of ▁score ▁is ▁based ▁on ▁the ▁comparison ▁made ▁between ▁the ▁r ated ▁house ▁and ▁a ▁reference ▁house ▁that ▁meets ▁a ▁desired ▁energy ▁code ▁or ▁standards . A ▁rating ▁of ▁ 5 0 ▁indicates ▁average ▁energy ▁performance , ▁while ▁a ▁rating ▁of ▁ 7 5 ▁or ▁more ▁indicates ▁best ▁performance . ▁More ▁the ▁score ▁obtained ▁by ▁a ▁house ▁more ▁will ▁be ▁the ▁energy ▁efficiency ▁of ▁the ▁house ▁and ▁the ▁high ▁rating ▁scores ▁have ▁many ▁direct ▁applications , ▁such ▁as ▁it ▁perm its ▁a ▁bu yer ▁to ▁quality ▁for ▁more ▁mort g age ▁compar atively . ▁ ▁Energy ▁use / Cost ▁prediction : HER S ▁generate ▁energy ▁use ▁and ▁cost ▁predictions ▁for ▁specific ▁end ▁uses ▁like ▁s ▁he ating / co ol ing
