Arif1 1 Management in Construction Research Centre (MIC), School of the Built Environment, University of Salford, Maxwell Building, M5 4WT Manchester, UK Email: a.abuzeinab@edu.salford.ac.uk; m.arif@salford.ac.uk Abstract: Business models describe the business logic of a particular company and green business model is when a company changes part(s) of its business model and thereby both captures economic value and reduces the ecological footprint in a life-cycle perspective. In this paper, business model literature is reviewed with the intention of promoting learning to understand the economic complexity of environmental sustainability in the construction context. Although the green construction literature does not explicitly deal with the changes of construction companies business model, there is a considerable research that implicitly investigates features and elements of the business models of green construction. Key features from this literature are: green value propositions should always be related to customer/stakeholder issues. Going green will improve relationships among stakeholders and with particular customers since key activities are performed in a greener manner. Knowledge and partnership are the most important resources needed to go green and moreover green branding is an important resource and can be a source of competitive advantage. To unlock green value proposition opportunities, cost structure and revenue models should be considered from a long-term perspective. Keywords: Business model, competitive advantage, green construction, green drivers, and sustainable construction. 1. Introduction Changing attitudes toward greener growth and sustainable development potential in financial markets are classified as critical factors when assessing a company longterm competitiveness and profitability. It is anticipated that addressing the economic values of sustainable activities will motivate more and more companies to adopt sustainable activities. In addition, there is an increasing consensus that the sustainability agenda and green practices are in high demand in the construction industry not only for their return on investment, but also because being environmentally responsible can boost a project profile and a developer reputation, resulting in a market edge over competitors (Fehrenbacher, 2010). Consequently, new concepts have emerged to express sustainability in the construction context. These concepts include: green construction; sustainable construction; and ecological construction. Green construction refers to practices and processes that are environmentally friendly, resource efficient, energy efficient, and generated less waste (Arif, Egbu, Haleem, Kulonda, & Khalfan, 2009). Kibert (2004) defined sustainable construction as “the creation and responsible management of a healthy built environment based on resource efficient and ecological principles.” For the purpose of the paper, sustainable construction or green construction can be used interchangeably (Kibert, 2007). Sustainable construction differs from conventional construction, in terms of the processes, designs, and materials used. Green construction adds tangible and intangible values to the construction services. The tangible values can be a higher profit as a consequence from lower internal costs, lower consumption of material, and resource efficiency while the intangible values can be a lower environmental impact, increased reliability, brand value, and reputation. In general, construction industry players who attempt sustainability have been strongly focused on environmental considerations (Guy & Kibert, 1998; Lützkendorf & Lorenz, 2005; Tan, Shen, & Yao, 2011). To profit or capture value from green construction, the comprehensive alteration of the business models has to be at the heart because business models are at the core of shaping all company activities. However, it seems there are no explicit studies on what changes are common or required in the construction companies business models, when they are involved in green practices or projects. Therefore, this paper identifies and maps business model changes relative to green or sustainable construction through a review of literature, and reviews main drivers and benefits of adopting green construction. It is worth noting that “construction” here is used in a broader sense to include property development, construction companies, material suppliers, consultant, and design companies. Following this introduction, the reminder of this paper will be organised as follows: in Section 2 we present research method followed by literature review of the business model including definition and its relation to the strategy in Section 3. Section 4 presents a conceptual green business model and Section 5 reviews the green construction literature to explore how it deals with construction companies business model elements, when they go green. Finally, key issues from the literature are grouped together for conclusion and indicate future research in Section 6. 2. Method This is a two stage literature review paper. Firstly, since the aim of this paper is to explore business models concepts, a review of the literature, across the disciplines of business and management, is conducted with the intention of understanding the economic complexity of environmental sustainability in the construction context. Key papers were identified using Google Scholar and Harvard Business Review databases in addition to the book entitled Managing Green Business Model Transformations. These were studied to understand the concept of business models and green business models in terms of important concepts and elements. These concepts and elements were subsequently used, in the second stage, to analyse relevant papers in green construction literature. Green construction literature was collected from Emerald “literature reviews collection” and EBSCO databases. The terms of “green construction” and “sustainable construction” were used to search in abstracts. 3. The Emergence of Business Models In recent years, business model has been the focus of significant attention by both scholars and practitioners (Zott, Amit, & Massa, 2010). In general, they are using the term “business model” to express the business logic of a particular firm, the way it does business, how it creates value for both its stakeholders and customers, and how it captures this value and turns it into profit (Aspara, Lamberg, Laukia, & Tikkanen, 2011; Baden-Fuller & Morgan, 2010; Chesbrough & Rosenbloom, 2002; Osterwalder & Pigneur, 2002; Teece, 2010). 3.1. Business Models and Strategy The business model concept extends central ideas in business strategy and its related theoretical foundations. However, the business model needs to be distinguished from the business strategy (Sommer, 2012). Zott et al. (2010), identified two main differentiating factors between business models and strategy. Firstly, strategy is more concerned with competition, whereas the business model is more concerned with value creation, cooperation and partnership. In general, the business strategy of a firm focuses on value capture and competitive advantage, while the business model combines a focus on sustainable value creation and value capture. Secondly, the focus of the business model is on the value proposition with emphasis on the customer role, which is less evident in business strategy literature. According to Sommer (2012) the business strategy is a principle plan for the future success of a business in a dynamic and competitive environment. In contrast the business model can be viewed as a logic or blueprint for a strategy to be implemented through organisational structures, processes, and systems and thereby creating and capturing economic value. Therefore, the business model concept is important when translating business strategy into business processes. In addition, modern phenomena, such as globalisation and the sustainability movement have further contributed to the importance of the business model concept. A detailed definition of the business model is presented in the next section. 3.2. Business Model Definitions Business model is a relatively new concept but it lacks a single definition, however, the agreed concept is related to value creation for customers and value capture. Therefore, business model promotes a dual focus on value creation and value capture (Afuah, 2004; Nielsen & Bukh, 2011; Osterwalder & Pigneur, 2002; Zott et al., 2010). A more detailed definition is provided by Slywotzky (1996) who sees the business model as the entirety of how a company selects its customer, differentiates and defines its offerings, defines the tasks it will deliver itself and those it will outsource, channels its resources, selects a market, creates value for customers, and captures value (profit). In summary, “A business model describes the rationale of how an organisation creates, delivers, and captures value.”(Osterwalder & Pigneur 2010, p.14). 4. A Conceptual Green Business Model As management and economic sciences still lack a broadly accepted single definition of a business model, it comes as no surprise that theoretical research on green business models are few at this point in time (refer to Section 3 above for more details). However, there are two major works on green business models which based on extensive theoretical foundation and empirical data from different industries (for more detailed discussions see (FORA, 2010; Henriksen, Bjerre, Almasi, & Damgaard-Grann, 2012; Sommer, 2012). Sommer (2012) suggested that the distinct common feature among all green business models is their advanced environmental performance – whatever form this might take. In addition, he defined a green business model, as a business model that represents a significant improvement on the whole environmental performance relating to its entire value chain system, as compared to that of a conventional business model. This improvement is directly attributable to the business model through the different configuration and design of its elements. A similar definition and holistic perspective on green business model innovation is held by (Henriksen et al., 2012) who said “Green business model innovation is when a business changes part(s) of its business model and thereby both captures economic value and reduces the ecological footprint in a life-cycle perspective.” To develop the current understanding of green business model, the reduction of ecological footprint can include changes to firm products, services, processes, and policies, such as reducing energy consumption and waste generation, using renewable resources, and implementing environmental management system (Bansal & Roth, 2000). In order to develop a green business model, business model elements have to be defined and listed first. Osterwalder is one of the few authors who delivered comprehensive works on business models (Osterwalder, 2004; Osterwalder, Pigneur, & Tucci, 2005). The business model canvas tool, developed by the author (Osterwalder & Pigneur, 2010), is internationally acknowledged as a practical tool to analyse companies business models (see Fig.1. for details). It contains nine elements covering four main pillars of a business: the Product pillar describes what is offered to the customer; the Customer Interface pillar describes the customer and how the offering is delivered; Infrastructure Management deals with value creation aspects for the customer and can include value created internally or externally with aid of partners and finally the Financial Aspects pillar outlines how the company plans to make money with its business model. Key Partners Key Activities Key Resources Cost Structure Value Proposition Customer Relationship Customer Segment Channels Revenue Streams Fig. 1. Business Model Canvas (Osterwalder & Pigneur, 2010) As illustrated in Fig.1 above, the business model canvas gives a company a simple yet powerful tool to understand its current business model, in order to systematically challenge the ways it does business and thereby enables the company to think differently and create new alternative business models. According to Osterwalder and Pigneur (2010) key activities are defined as: activities that need to be performed to create customer value whilst key resources are the assets required to offer and deliver value to the customer. Afuah (2004), in his book on business models, regarded capability as an important element of the business model. He stated that capabilities are important because it usually takes more than resources or assets to offer value to customers. A firm capacity or ability to convert its resources into customer value (something that customers want) and then earn profits, is usually called capability. Since this research is adopting a holistic view to develop a conceptual green business model, the capability element will be considered. Afuah categorised resources into three different groups: tangible, intangible, and human. Tangible assets can be physical, such as equipment or financial, such as cash: while intangible assets are nonphysical and nonfinancial such as brands, relationships with vendors, and knowledge, which can be excellent sources of profits. Human assets are the knowledge and skills that employees carry with them. The business model elements applied in this work can be found in Table 1. Table 1: Business model elements applied in this work (Afuah, 2004; Osterwalder & Pigneur, 2010; Sommer, 2012) No Business model element Description 1 Value Proposition 2 3 Customer/ stakeholder segment Relationship 4 Channels 5 Key Activities 6 Brand 7 Employees 8 Information 9 Knowledge 10 Technology 11 Capability 12 Partnership 13 Cost Structure 14 Revenue Model Gives an overall view of a company bundle of products and services that are of value to the customer. Describes the segment of customers/critical stakeholder whom a company wants to offer value to. Describes the kind of link a company establishes between itself and the customer/stakeholder. Describes the means of getting in touch with the customers/stakeholder. Outlines the most important activities need to be performed to create value to the customer. The essence of a product or services: identity, reputation, image, intangible asset. Human assets with their experience, training, relationships, knowledge, and insights are a crucial factor for any company.

Examples include information on customer preferences, or the firm’s environmental footprint. Knowledge required by company managers and employees to realise their business models and strategies. Can relate to both products and processes. It includes knowhow like patents or licenses, and the systems that a company uses to run its business model The ability to execute the company business model or resources needed to turn concept into reality. A partnership is a voluntarily initiated cooperative agreement between two or more companies in order to create value for the customer. Allows companies to access external resources Describes the representation in money of all the means employed in the business model. Describes the way a company makes money through a variety of revenue flows. 5. Green Construction from a Business Model Perspective Existing research shows that the construction industry is a major contributor to environmental problems, for example (Mcdonald & Smithers, 1998; Tam, Tam, & Tsui, 2004; Tan, Shen, & Yao, 2011). Consequently, protecting the environment has become one of the main issues for the construction industry across the globe and the construction industry has begun to adopt environmental sustainability as a central part of its strategic business management. (Kjaerheim, 2005; Lozano, 2008; Park & Ahn, 2012). Evidence has shown that adopting an environmental approach leads to significant business benefits: for example, highly valuable green reputation, improved stakeholder relations between the demand and supply side, innovation opportunities, reducing life-cycle cost, efficiency, increased business productivity and achieving long-term profits (Bartlett & Howard, 2000; Hodges, 2005; M. Khalfan, 2000; Liu, 2006; Sacks, Nisbet, Ross, & Harinarain, 2012; Vatalis, Manoliadis, & Charalampides, 2011; von Paumgartten, 2003). Yet, despite all the ink spilt and words spoken, green values are still relatively poorly appreciated more widely in the construction context. For example, Abd. Hamid and Kamar (2012) state that one of the challenges of adopting sustainable construction is that companies do not know how to act upon the sustainability value “Although the values are generally at the right place, the problem is how to enact them.” This research suggests that the business model concept can be a means to resolve this challenge. Although construction literature does not specifically deal with changes to construction companies business models, there is considerable research that implicitly investigates features and elements of green construction business models (Mokhlesian & Holmén, 2012). The main features and elements of the business models, mentioned in green construction literature, are explained below. The major drivers behind adoption of green construction are: legislative, ecological, social, and market drivers. (Refer to Table 2 for more details). These four groups of drivers, in particular, the market drivers, for example client requirements, have encouraged the construction industry to create green value propositions - their products or services are more environmentally sound when compared to conventional practices (Mokhlesian & Holmén, 2012). A company may derive a reputational value (brand) from green services, by changing the criteria that are most relevant to the customer through for instance, revised environmental processes and practices which both redefines the competition and helps customers to become green. Also cost savings, in the operational phase of a building with green features, have encouraged more stakeholders including clients to ask for green because they see a long-term economic benefit (Bartlett & Howard, 2000). Green value propositions are thus always associated with the customer/stakeholder segment. The customer/stakeholder segment represents the company choice of relevant groups such as customers, regulators, and investors to which the company value proposition is intended to appeal: by offering superior value/ green differentiation to these defined groups, or by facilitating access to new target customers or by founding deeper customer relationships in particular with eco-minded customers (Pitt, Tucker, Riley, & Longden, 2009; Shen & Yu, 2012).

(2009) The principal difference between green construction and conventional construction is that the former performs its activities in a more environmentally friendly manner by for instance, generating less waste, using renewable sources, and consuming less energy. For a construction company to perform in a greener manner it needs appropriate resources to do so. These resources can include: knowledge, information, employee training, capability, and appropriate technology to perform green activities. In particular, the literature emphasises the knowledge necessary to perform and achieve green practices. For example, Gluch, Gustafsson, and Thuvander (2009) investigated environmental knowledge needed for green innovation in the construction industry. They suggested that companies can achieve green innovation through consideration of internal environmental knowledge sources and external knowledge exchange. Furthermore, the Construction Confederation Environmental Forum (CCFF) has six sustainability objectives. Of these, two objectives are related to knowledge “share and disseminate knowledge and best practice; increase environmental knowledge and skills in the industry by developing practical training tools” (CCEF, 2001). In a related vein, Alkhaddar, Wooder, Sertyesilisik, and Tunstall (2012) highlight the importance of raising awareness among construction employees on sustainability through deep learning approach and training. Different authors have mentioned that sustainability reporting (information) is increasing because companies are demanded by different stakeholders to demonstrate their commitment regarding sustainability issues (Kimmet, 2009; Pitt et al., 2009). Partnership is a core theme in the construction research agenda (Dakwale, Ralegaonkar, & Mandavgane, 2011; Fiedler & Deegan, 2007; Ingirige & Sexton, 2006; M. M. Khalfan, McDermott, Li, & Arif, 2008) and it takes different forms (project-based, environmental collaboration and joint ventures) and names (alliances or collaboration). In addition, green construction literature highlights the importance of a collaborative approach. In a review of the literature on improving environmental performance of buildings, through increased energy efficiency, Dakwale et al. (2011) pointed out that in order to improve the overall environmental performance of a building: policy makers, architects, energy managers, construction managers, structural engineers, and consultants must work more closely and collaborate together. Additionally, the construction managers seek to collaborate with environmental groups because of pressures from stakeholders such as government. Another reason for such collaboration is the desire of a company to be associated with another company that has green reputation- brand (Fiedler & Deegan, 2007). The cost element is frequently cited in green construction literature. The reason for this is likely to be due to the widely held belief that going green is associated with high cost (Vatalis et al., 2011). On the other hand, going green is a means of reducing the cost of capital by accessing public and private funding and it reduces the cost of running and maintaining the building over its life-cycle (Mokhlesian & Holmén, 2010). For this reason, life cycle cost (LCC) is frequently associated with environmental sustainability (Kloepffer, 2008). LCC is an economic model to evaluate a project life cycle. The objective of LCC analysis is to choose from a series of alternatives to attain the lowest long-term cost of ownership. Many companies in green construction realise substantial savings in internal cost structure, by implementing environmental improvement measures. Such improvements will lead to lower costs of compliance by reducing costs related to emissions; treatment costs and taxes, productivity developments, more efficient processes and new market opportunities which can also result in increased revenues (Lankoski, 2006; Nidumolu, Prahalad, & Rangaswami, 2009; Porter & Van der Linde, 1991, 1995; SinclairDesgagné, 1999). Consequently, the cost structure and revenue models have to be taken together - lower internal costs will lead to increased revenues. 6. Conclusion and Future Research In this paper, business model literature has been reviewed with the intention of promoting learning into environmental sustainability in the construction context from the perspective of economic considerations. The rational of this research focusing on the business models were the dual focus of the business models on value creation and value capture and its focus on the value proposition with emphasis on the customer role. This holds true for the construction industry because the customer/client is a main driver or trigger for a construction product. In addition, customer satisfaction, performances, and profitability are directly relevant to the construction industry. The business model concept will be useful in understanding how the construction companies deal with green issues. Key features from the literature are: (1) green value propositions should always be related to customer/stakeholder issues; (2) going green will improve relationships among stakeholders and with particular customers because (3) key activities are performed in a greener manner; (4) knowledge and partnership are the most important resources needed to go green and have received considerable attention from scholars; (5) the importance of collaboration with stakeholders inside (employees) and outside (customers and suppliers) the company (6) green branding is an important resource and can be a source of competitive advantage; (7) and to unlock green value proposition opportunities cost structure and revenue models should be considered from a long-term perspective. It is proposed future research will be further carried out to review different business model elements with a view to developing a generic green business model. In addition, we will develop instruments for Phase 1 of data collection: pilot study. The pilot study will give directions on how to collect relevant data from construction companies for Phase 2 which is the main data collection phase. References: Abd. Hamid, Z., & Kamar, K. A. M.
