建筑节能计算相关公式及参数

节能计算单一材料层的热阻应按下式计算：

R＝δ/λ（附2.1）式中R——材料层的热阻（㎡·K/W）；δ——材料层的厚度（m）；λ——材料的导热系数〔W/（m·K）〕，应按本规范附录四附表4.1和表注的规定采用。围护结构的传热阻应按下式计算：Ro＝Ri+R+Re(附2.4)式中Ro——围护结构的传热阻(㎡·K/W)；Ri——内表面换热阻(㎡·K/W)，应按本附录附表2.2采用；Re——外表面换热阻(㎡·K/W)，应按本附录附表2.3采用；R——围护结构热阻(㎡·K/W)。热惰性指标：D＝RS(附2.5)式中R——材料层的热阻(㎡·K/W)；S——材料的蓄热系数[W/(㎡·K)]。常用建筑材料热物理性能计算参数序号材料名称密度计算参数修正系数λS比热容C，kJ/(kg·K)蒸汽渗透系数，g/(m.h.Pa)1.混凝土1.1普通混凝土钢筋混凝土25001.7417.200.920.00001581.00碎石混凝土23001.5115.360.920.00001731.00卵石混凝土上海21001.2813.570.920.00001731.00浙江23001.5115.361.2轻骨料混凝土膨胀矿渣珠混凝土20000.7710.490.9618000.639.0516000.537.87自然煤矸石炉渣混凝土浙江15000.7609.541.050.00009001.00山东17001.0011.680.000054815000.769.5400000090013000.567.630.0001050粉煤灰陶粒混凝土17000.9511.401.050.000018815000.709.160.000097513000.577.780.000105011000.446.300.0001350粘土陶粒混凝土16000.8410.361.050.000031514000.708.930.000039012000.537.250.0000405页岩渣、石灰、水泥混凝土13000.527.390.980.0000588水泥焦渣（湖南）页岩陶粒混凝土15000.779.651.050.000031513000.638.160.000039011000.506.700.0000435火山灰渣、砂、水泥混凝土17000.576.300.570.0000395浮石混凝土15000.679.091.0513000.537.540.000018811000.426.130.00003531.3轻混凝土加气混凝土5000.192.811.25～1.50.0000998加气混凝土6000.203.001.25～1.50.0000998加气混凝土7000.223.591.25～1.50.0000998泡沫混凝土5000.192.811.050.00011102.砂浆和砌块2.1砂浆水泥砂浆18000.9311.371.050.00002101.00石灰水泥砂浆17000.8710.751.050.0000975石灰砂浆16000.8110.071.050.00004431.00石灰石膏砂浆15000.769.441.05保温砂浆8000.294.441.05混合砂浆17000.87010.751.050.00009751.00建筑用砂16000.5808.261.011.00复合硅酸盐保温砂浆3500.0751.19聚苯颗粒保温胶浆浙江2300.0601.021.152500.0601.021.30上海2300.0601.022500.0601.02湖南2300.0590.951.20稀土复合保温砂浆6000.0851.96海泡石保温砂浆3000.0601.021.20聚合物保温砂浆6500.1103.501.20吉能士（JNS）系列高性能复合保温砂浆550～7000.100～0.1252.1～2.7R.E-I（内墙）、II（外墙）、III（屋面）复合保温材料400～6000.060～0.0853.16珍珠岩保温砂浆5000.152.8JMS轻质砂浆12000.24～0.302.3GTN隔热保温砂浆≤5000.0852.2砌体重砂浆砌筑粘土砖砌体18000.8110.631.050.0001050轻砂浆砌筑粘土砖砌体17000.769.961.050.0001200灰砂砖砌体19001.1012.721.050.0001050硅酸盐砖砌体18000.8711.111.050.0001050混凝土多孔砖砌体14500.7387.251.00砼多孔砖（河南）0.737.331.00陶粒混凝土多孔砖（湖南）0.60混凝土多孔砖（湖南）0.74普通混凝土空心砌块（湖南）0.86KP1型烧结多孔砖砌体14000.5807.92单排孔混凝土空心砌体9000.8607.48双排孔混凝土空心砌体11000.7928.42三排孔混凝土空心砌体13000.7507.92蒸压灰砂砖砌体19001.10012.721.050.00010501.00轻骨料混凝土空心砌块11000.7506.01砂加气砌块（B05级）浙江5000.1302.731.36上海500～5500.1302.73砂加气砌块（B04级）浙江4000.1102.261.36上海400～4500.1102.26加气混凝土砌块（B07级）7000.2203.591.050.00009881.121.50加气混凝土砌块（B05级）5000.1902.811.050.00011101.251.50炉渣砖砌体17000.8110.431.050.0001050重砂浆砌筑26～36孔粘土多孔砌体14000.587.921.050.0000158重砂浆砌筑26～36孔粘土空心砖砌体14000.587.921.050.0000158粘土多孔砖KPI,KM114000.587.92240/190烧结多孔砖14000.587.92烧结页岩砖0.87粘土实心砖18000.8110.631.00灰砂砖19001.1012.72240炉渣砖17000.8110.43240煤矸石烧结砖17000.639.05粉煤灰烧结砖16000.507.82粉煤灰蒸养砖16000.628.71煤矸石多孔砖14000.547.60混凝土双排孔砌块13000.685.88190加气混凝土砌块7000.223.59250粉煤灰淤泥烧节能砖1500~16000.36~0.42S1-2型粉煤灰淤泥烧节能砖1000~12000.32~0.36S3-4型粉煤灰淤泥砖17000.507.82240/190混凝土单排孔砌砖12001.025.88190混凝土砌块内加气砼碎块13000.337.641903.热绝缘材料3.1纤维材料i矿煤、岩棉、玻璃绵板浙江70～2000.0480.771.340.00048801.30山东≤800.0500.591.220.0004880湖南80～2000.0450.751.22微孔硅酸钙板2200.0651.261.20憎水性珍珠岩板4000.1202.031.20石膏板10500.3305.281.050.00007901.00膨胀聚苯板上海18～200.0460.400.0550.47浙江18～200.0420.361.380.00001621.101.30高密度膨胀聚苯板30~350.0400.33挤塑聚苯板25~320.0300.321.10半硬质矿（岩）绵板100～800.0480.770.0480.77矿棉、岩棉、玻璃棉毡上海60～1200.0490.62山东≤700.0500.581.340.000488070～2000.0450.771.34半硬质玻璃绵板32～480.0450.440.0450.44玻璃棉毡240.0490.34硬质矿绵板3000.0601.26石膏玻璃绵板3500.0701.430.0701.43泡沫玻璃保温板150～1800.0660.81水泥聚苯板浙江3000.0901.541.30上海3000.0901.540.0901.54岩棉、矿棉玻璃棉松散料70～1200.0450.510.840.0004880≤700.0500.460.840.0004880麻刀1500.0701.342.103.2膨胀珍珠岩、蛭石制品水泥膨胀珍珠岩8000.264.341.170.00004206000.213.441.170.00009004000.162.491.170.0001910沥青、乳化沥青膨胀珍珠岩4000.122.281.550.00002933000.0931.771.550.0000675水泥膨胀蛭石3500.141.991.05憎水膨胀珍珠珍珠岩制品2500.0721.24煤矸石砌块内填膨胀珍珠岩13000.273.251903.3泡沫材料及多孔聚合物聚乙烯泡沫塑料1000.0470.701.38聚苯乙烯泡沫塑料300.0420.361.380.0000162聚氨酯硬泡沫塑料300.0330.361.380.0000234聚氨酯泡沫塑料55～700.0270.47硬泡聚氨酯650.0270.361.380.00002341.20（XPS）30～400.0300.54硬质聚氨酯泡沫塑料≥30<0.024聚氯乙烯硬泡沫塑料1300.0480.791.380.0000225钙塑1200.0490.831.59泡沫玻璃1400.0580.700.84泡沫石灰3000.1161.701.05炭化泡沫石灰4000.142.331.05泡沫石膏5000.192.781.050.00003754.木材、建筑板材4.1木材橡木、枫树7000.174.902.510.0000562橡木、枫树7000.356.932.510.0003000松木、云杉5000.143.852.510.0000345松木、云杉5000.295.552.510.00016804.2建筑板材胶合板6000.174.572.510.0000225软木板3000.0931.951.890.00002251500.0581.091.890.0000285纤维板10000.348.132.510.00012006000.235.282.510.0001130石棉水泥板18000.528.521.050.0000135石棉水泥隔热板5000.162.581.050.0003900石膏板10500.335.281.050.0000790ALC外墙板6500.14～0.172.18水泥刨花板10000.347.272.010.00002407000.194.562.010.00001050稻草板3000.132.331.680.0003000木屑板2000.0651.542.100.00026305.松散材料5.1无机材料锅炉渣10000.294.400.920.0001930粉煤灰10000.233.930.92水泥焦渣11000.426.131.50高炉炉渣9000.263.920.920.0002030浮石、凝灰岩6000.233.050.920.0002630膨胀蛭石3000.141.791.052000.101.241.05硅藻土2000.0761.000.92膨胀珍珠岩1200.070.841.17800.0580.631.175.2有机材料木屑2500.0931.842.010.0002630稻壳1200.061.022.01干草1000.0470.832.016.其他材料6.1土壤夯实粘土20001.1612.991.0118000.9311.031.01加草粘土16000.769.371.0114000.587.671.01轻质粘土12000.476.361.01建筑用砂16000.588.261.01轻质混合种植土12000.476.361.506.2石材花岗岩、玄武岩28003.4925.490.920.0000113大理石28002.9123.270.920.0000113砾石、石灰岩24002.0418.030.920.0000375石灰石20001.
