Purpose

This study aims to examine the effects of green construction site practices on the economic performance of projects executed by “class A” contractors in Nigeria. The effects of stormwater management, materials management waste management and energy management on economic performance were examined.

Design/methodology/approach

Data was collected through a survey of class A contractors in Nigeria, and 168 usable responses were received. The partial least-squares structural equation modelling technique was used to analyse the collected data.

Findings

It was observed that all the green construction practices studied had significant effects on the economic performance of construction projects with the greatest effect from energy management.

Practical implications

The results imply that green construction practices generally lead to economic performance. The study has both theoretical and practical implications, as it helps both policymakers and contractors better understand the relationships between these variables of green construction practices and economic performance to better plan for their projects and for the government to formulate appropriate policies.

Originality/value

The study’s findings makes significant contributions to the ongoing discussion on the relationship between green construction practices and economic performance. The relationship established between stormwater management, waste management, materials management, energy management and economic performance in this study is different when compared with those in other similar studies.

绿色建筑对项目经济效益的影响

目的

这项研究旨在研究绿色建筑工地做法对尼日利亚“ A级”承包商执行的项目的经济绩效的影响。研究了雨水管理，物料管理废物管理和能源管理对经济绩效的影响。

设计/方法/方法

通过对尼日利亚A级承包商的调查收集了数据，收到了168份可用答复。使用偏最小二乘结构方程建模技术来分析收集的数据。

发现

观察到，研究的所有绿色建筑实践对建筑项目的经济绩效都有显着影响，而能源管理的影响最大。

实际影响

结果表明，绿色建筑实践通常会带来经济绩效。该研究具有理论和实践意义，因为它可以帮助决策者和承包商更好地理解绿色建筑实践的这些变量与经济绩效之间的关系，从而更好地计划其项目以及政府制定适当的政策。

创意/价值

该研究结果为正在进行的有关绿色建筑实践与经济绩效之间关系的讨论做出了重要贡献。与其他类似研究相比，本研究中雨水管理，废物管理，物料管理，能源管理和经济绩效之间建立的关系是不同的。
