Ib qho kev hloov pauv tseem ceeb tab tom pib hauv kev lag luam fenestration, raws li kev lag luam rau kev kho dua tshiabqhov rooj thiab qhov raisnyob rau hauv cov tsev nyob uas twb muaj lawm tam sim no decisively outpaces xav tau los ntawm tshiab kev tsim kho tej yaam num. Qhov kev hloov pauv no mus rau "Era of Retrofitting" yog qhov tsim kho cov khoom tsim kho, cov tswv yim muag khoom, thiab cov qauv kev pabcuam, muab cov tswv tsev xav tau kev txuag hluav taws xob tam sim, kev zoo nkauj dua tshiab, thiab kev txhim kho kev ua haujlwm ntawm lub plawv ntawm kev lag luam kev loj hlob.
Qhov kev hloov pauv no yog tsav los ntawm kev sib xyaw ua ke ntawm kev lag luam, kev sib raug zoo, thiab ib puag ncig. Kev nce nqi kev tsim kho tshiab, ua ke nrog cov nqi qiv nyiaj ntau dua, yog qhov yuam cov tswv tsev los nqis peev hauv thiab kho lawv cov khoom tam sim no. Tib lub sijhawm, kev paub txog kev siv hluav taws xob ntau ntxiv, kev txhawb nqa los ntawm tsoomfwv cov nyiaj rov qab thiab kev txhawb siab, yog txhawb kev hloov pauv uas muaj kev txo qis hauv cov nqi hluav taws xob. Cov khoom zoo nkauj thiab kev ua neej nyob muaj zog sib npaug; retrofitting nrog niaj hnubqhov rooj thiab qhov raisyog ib txoj hauv kev zoo tshaj plaws los ua kom lub tsev zoo dua qub, txhim kho kev nplij siab los ntawm kev txo suab nrov, thiab txhim kho kev siv tau nrog cov yam ntxwv niaj hnub zoo li yooj yim - iav huv si thiab ruaj ntseg xauv tshuab.
Rau manufacturers, distributors, thiab installers, lub lag luam kev hloov pauv xav tau ib txoj hauv kev tshiab. Lub hom phiaj yog txav los ntawm kev muab cov xaj xaj ntau rau cov neeg tsim khoom ncaj qha rau - mus rau - kev lag luam rau cov neeg siv khoom, siab - cov kev pabcuam kev sib tham, thiab ua kom yooj yim hauv tsev ntsuas thiab txheej txheem kev teeb tsa. Cov khoom lag luam yuav tsum tau tsim kom yooj yim rov qab mus rau hauv cov laus, tsis yog- tus qauv qhib, thiab cov lus piav qhia txog kev muag khoom hais txog kev rov qab sai ntawm kev nqis peev los ntawm kev txuag hluav taws xob thiab cov khoom muaj nqis ntxiv. Raws li lub retrofit lag luam solidifies nws dominance, kev vam meej nyob rau hauv lubqhov rooj thiab qhov raiskev lag luam yuav nce ntxiv nyob ntawm qhov muaj peev xwm los koom nrog, qhia, thiab ua haujlwm rau tus tswv tsev.
