Класс энергоэффективности определяется по показателю энергоэффективности К по формуле:

K = Kr + ki + Ka + kt + Ks = 0.83 + 0.19 + 1 + 0.8 + 1.25 = 4.07

Где

Kr — критерий термической неоднородности конструкции, определяемый согласно результатам экспериментальных испытаний конструкции

Kr = RΣпр/RΣ = 0.83 (согласно протоколу № 101к/18 от 29.11.2018 г., см. внизу).

где RΣ — сопротивление теплопередачи основного поля конструкции.

ki — критерий воздухопроницаемости теплоизоляционного и воздухозащитного слоя

ki =ri [ і10 / іb] = 0.5 ⋅ 0.228 / 0.6 = 0.19

где

ri— масштабный коэффициент, для конструкций фасадной теплоизоляции согласно ДСТУ В.2.6-35 равняющийся 0,5;

іb — базовое значение воздухопроницаемости, равняющееся 0,6 кг/(м·год· Па);

і10 — значение воздухопроницаемости материала при перепаде давления 10 Па, определяемое экспериментально согласно ДСТУ Б В.2.6-37.

Ka — критерий горючести теплоизоляционного и отделочного слоев конструкции Ka = 1 (от 0,25 до 1 , если слои принадлежат к группе Г4-Г1, НГ материалов).

kt — критерий тепловой надежности конструкции, после ресурсных испытаний

kt = 5 ⋅ (Rτ / R0) – 4 = (5 ⋅ 3.31 / 3.44 – 4) = 0.8

где

Rτ — экспериментальное определенное значение теплового сопротивления конструкции после ресурсных испытаний;

R0 — базовое значение теплового сопротивления конструкцииї.

Ks — критерий долговечности системы после воздействия климатических факторов, определяемый по ДСТУ Б В.2.6-36 (для штукатурных систем) или ДСТУ Б В.2.7-130, режим II (для других систем) и ДСТУ-Н Б ETAG 017

Ks=1,25 ⋅ [Θδ/ Θτ] = 1.25 ⋅ 25 / 25 =1.25

где

Θδ — базовое значение срока эффективной эксплуатации конструкции, равняющейся 25 условным годам;

Θτ — экспериментальное определенное значение срока эффективной эксплуатации конструкции, устанавливаемое в условных годах, на основе методик ДСТУ Б В.2.6-36:2008 (приложение Д), ДСТУ Б В.2.7-130, ДСТУ-Н ETAG 017.
