Awareness and Implementation Challenges of the Green Retrofitting in Building Enclosure in the Nigerian Construction Industry

Abstract

Abstract This research work aims at examining awareness and implementation challenges of green retrofitting in building enclosures among professionals in the Nigerian construction industry. The study identifies the varying green retrofitting used in building enclosures and investigates its level of awareness and the factors affecting its adoption among professionals in the Nigerian construction industry. The sample was 100 comprising professionals in the construction industry selected randomly using cluster and purposive sampling techniques; and the response was 60%. Data were analyzed using frequency, mean and rank. The findings from the study revealed that out of the 20 green retrofitting used in building enclosures, the construction professionals are more aware of green roofs, high-quality glazing, reflective roofs, energy-efficient windows and doors, and shading device which include louvers. Also, top among the implementation challenges of green retrofitting used in building enclosure among construction professionals include limited knowledge, cost of fixing green retrofitting, skills gap, reluctance to adapt, and poor infrastructure are the major factors. The study recommend that government and professional bodies should sponsor innovative training approaches aimed at addressing skill shortages. This could be in form of schemes such as micro credentials and on-the-job training.
