Where on-site renewable energy is included in the ERI calculation, buildings must meet or exceed the thermal envelope requirements in Table 402.1.2 of the 2015 IECC, but the 2009 IECC envelope backstop will remain in effect for buildings without on-site generation. In the 2018 IECC, there continues to be four energy conservation compliance paths for residential construction: 2. Answer:The BC Building Code is a provincial regulation for new construction and building alterations, establishing minimum standards for safety, health, accessibility, fire and structural protection of buildings, and protection of the building or facility from water and sewer damage. 37).

Therefore it is important to note that when any type of fall prevention device or opening control device is used, it shall not reduce the required opening size of egress windows when the mechanism is released. The U-factor of skylights in climate zones 4 to 8 is not to exceed 0.75. Previously, there was some variation in the energy performance requirements for residential buildings that were included in both the IECC and the IRC. hk\J}QbudH=?yYURGvr C"u}WnpC=q%bvOP!bJ9`RZ?F[KBP}jHj/iCV~'f_'_Y^}W[?vaZ>UOwn'X}=o_nO?~toO|}{wHU/}_m'd?}gVsovR~x_}??/o!5?{s{_o^[\//oSo377>[Oom2?|\Q:0tpC8C rhq)zJ8EYk5Ur22SJl)5kbuJr,6^[8n4a2uTQPgyhr'Trs~^:pW7r10ed` Me"'`b-qN]9l'I*Uooj?6)v7G#?}+[3l|(32.#=jOXRzb 6l,;>[:f{6u#0Bg[m[~=\O5YGMVdM$_8O4 :#C5O'S >s3 OHfck>)I1N9X!/31)89mCUggqX,vkJ1Y}9$+vgw1ct8}y9~xuyms]qO$cu52#gNJ;6,f1-1SLhBvO|/^~VY/{KnS8xt)^z=K>.-fjE0{AV!kAnV`tCBgg.Lo@Sj$h6^}{2,TTLD5 V_'flG}mQN!3k=Md|BMp&L#Jg! ^&co^aBh)r.,cy5z(04lyAm&VF>@Vh#,SVnX$Gs7!?2#' d2Yq@Fh`X yl\8EgZo6O)p2c7dEk`6\CKkW5_O"M;^{ #*&zm]::cf4=iRF,d$a n 2. If you are installing windows within 2 feet of a door and lower than 5 feet from the ground, you need tempered glass in the windows, even though these might be higher than 18 inches from the ground. However, for example if the window is operable, the grade on the exterior is greater than 72 inches in height, but the sill height is 40 inches in height at the interior, then no prevention is necessary since the interior sill height is not less than 24 inches. 1468 0 obj <>/Filter/FlateDecode/ID[<96E6B7F287667F4FABB3DD517F82A1F4>]/Index[1436 63]/Info 1435 0 R/Length 141/Prev 405955/Root 1437 0 R/Size 1499/Type/XRef/W[1 3 1]>>stream 29).
