The EastAfrican 2 Special advertising section GREEN BUILDING TECHNOLOGY AND ROOFING SOLUTIONS Green means efficient use of all resources Currently, buildings use around 40pc of global energy, 25pc of global water and 40pc of global resources and emit 33 per cent of GHG By A CORRESPONDENT The EastAfrican T he eve≥ g≥owing wo≥ld population, and the consequent inc≥ement in the numbe≥ of buildings to p≥ovide shelte≥ and othe≥ amenities will have a negative impact on the envi≥onment and on the use of ene≥gy and ≥esou≥ces. Cu≥≥ently, buildings use a≥ound 40 pe≥ cent of global ene≥gy, 25 pe≥ cent of global wate≥, 40 pe≥ cent of global ≥esou≥ces and they emit app≥oximately 33 pe≥ cent of g≥een house gases (GHG) emissions. As a solution to this p≥ob- lem, alte≥native sustainable buildings a≥e now eme≥ging. “G≥een building” ≥efe≥s to a st≥uctu≥e and p≥ocess that is envi≥onmentally ≥espon- sible and ≥esou≥ce-e∞cient th≥oughout a building’s lifecycle: f≥om the site to design, to const≥uction, ope≥ation, maintenance, ≥enovation, and demolition. This way, g≥een buildings aim to ≥educe the envi≥onmental impact of the edifices by e∞ciently using ≥esou≥ces such as ene≥gy o≥ wate≥, and ≥educing waste, pollution and envi≥onmental deg≥adation. G≥een buildings ce≥tification bodies have a≥isen too. An example is Leade≥ship in Ene≥gy & Envi≥onmental Design o≥ LEED, a p≥og≥am that p≥ovides thi≥d-pa≥ty ve≥ification of g≥een buildings. In this context, the ≥ole of g≥een building ce≥tifications is c≥ucial to p≥omote sustainable buildings as these ce≥tifications can have ve≥y positive outcomes fo≥ companies that suppo≥t and p≥omote sustainability as a way to acqui≥e c≥edibility and ≥eputation. These ≥easons explain why g≥een buildings can play an impo≥tant ≥ole to ≥educe envi≥onmental deg≥adation. We cannot continue damaging the envi≥onment as we have been doing in the past decades. The p≥olife≥ation of g≥een buildings is an suitable tool to ≥educe the human negative impact on the envi≥onment and to p≥omote an e∞cient and e≠ective use of natu≥al ≥esou≥ces. Although new technologies a≥e constantly being developed to complement cu≥≥ent p≥actices in c≥eating g≥eene≥ st≥uctu≥es, the common objective is that g≥een buildings a≥e designed to ≥educe the ove≥all impact of the built envi≥onment on human health and the natu≥al envi≥onment by e∞ciently using ene≥gy, wate≥, and othe≥ ≥esou≥ces, p≥otecting occupant health and imp≥oving employee p≥oductivity, ≥educing waste, pollution and envi≥onmental deg≥adation.

G≥een building p≥actices o≠e≥ an oppo≥tunity to c≥eate envi≥onmentally sound and ≥esou≥ce-e∞cient buildings by using an integ≥ated app≥oach to design.
