El enfoque sociotécnico considera los motivos, las actitudes, las cogniciones y los comportamientos de los usuarios al diseñar entornos de trabajo. Esta nota describirá esos fenómenos en entornos de oficina. También presentará un conjunto de herramientas para evaluar esos fenómenos y proporcionará pautas para mejorarlos.


USEr BEHAvIOr IN SmArT ANd SUSTAINABLE OffICES (SSO)
Recently, we are witnessing an increasing number of technological advances and sustainable solutions in the office buildings aimed at energy use reduction.These advances make the workplace environment constantly changing and the introduction of technology into work-life seems inevitable.However, the adoption of technological advances in organizations is not simple and even the most promising sustainable solutions may fail if the process of change neglects human or psychosocial aspects.The socio-technical approach takes an ecological view to these issues and proposes that, when modifying the environment, it is not enough to merely impose the new technologies, but it is necessary to take into account the employees, the machine-human fit, or the complexity of psychosocial phenomena at work.Thanks to these features, the psychosocial system can help to maximize the opportunities for introducing sustainable solutions and changes in organizations oriented at decreasing energy consumption.
The core of the BTA Climate-KIC Smart and Sustainable Offices (SSO) project is the assumption that the link between innovative and sustainable building systems and technologies with improved indoor environmental quality (IEQ) involves human factor at work.Thus, SSO adopts a user-centered approach that considers office users.Especially, it considers such psycho-social aspects as the office users' technologyrelated perceptions (e.g., of control), their attitudes related to energy-conservation, habits, self-efficacy for energy-saving behaviors, information about energy-saving options in the building, incentives, and goal conflicts.All these factors are considered in the SSO project as decisive for an efficient environmental user behavior in office buildings.In this way, the SSO project proposes that it is possible to decouple office users' comfort from the increase energy consumption, by taking into account psychological determinants of the office users' energy-relevant behaviors.
In the present technical note, we will present the method used in the SSO project to evaluate these phenomena that might serve as an assessment tool to improve the process of implementation of sustainable technology and solutions in office buildings and the positive energy-related outcomes of this implementation.

THE NEEd fOr A TECHNOLOgy-USErS' fIT fOr SUSTAINABLE SOLUTIONS
Technology developments have contributed to fast workplace changes (Lee & Brand, 2005) and often led to transformations in basic office functions (Turner & Myerson, 1998).There is a number of existing, relatively practical building technologies stemming from advances in sustainable technologies, such as increased ventilation, reduced air recirculation, improved filtration, ultraviolet disinfection of air, reduced space sharing, and reduced occupant density that can have positive consequences on workers (Fisk, 2000).Other recent popular attempts aimed at reducing costs and often introduced in the office setting include such energy-efficient solutions as occupancy sensors that control automatic lighting, automatic blinds systems, or central HVAC systems, drastically limiting the control of the office user over his/her working environment.This physical context with new technologies being introduced may constrain people's choices and the perception of control over their environment.According to the reactance theory (Brehm, 1966), such limitations to freedom may give way to psychological reactance, that is, a "motivational state hypothesized to occur when a freedom is eliminated or threatened with elimination" (Brehm & Brehm, 1981, p. 37).In turn, reactance may involve behaviors aimed at reestablishing the threatened freedom through the tendency to engage in the prohibited actions (Brehm, 1966).That is how new sustainable solutions may provoke an effect opposite to the expected one and incite non- Thus, "achieving energy conservation is a twofold challenge, partly technical and partly human" (Constanzo, et al., 1986, p. 521).The development of sustainable and energy-conserving technologies is necessary to decrease energy consumption; however, unless adopted by its users, the impact of these technical innovations will be insignificant (Constanzo, et al., 1986, p. 521).This is why, in case of energy consumption-related issues, in order to address the human aspect of energy saving, more consideration should be given to its social-psychological dimension and aspects (e.g.Constanzo, et al., 1986;DeMeo & Taylor, 1984), to consider a broader social context, as well as improve communication between decision-makers, technical experts, and other stakeholders (e.g., office users), and ensure a more inclusive participation (Owens & Driffill, 2008).In other words, in the presence of an increasingly complex technology, it is necessary to ensure the machine-human fit (Peiró, 1991).

THE SOCIO-TECHNICAL ApprOACH TO INTrOdUCINg TECHNOLOgy IN OrgANIzATIONS
The presence of an increasingly complex technology highlighted the necessity of developing human engineering and stressed the need to ensure acceptable ergonomics and adapt the technology to the worker (Peiró, 1991).These significant developments in technology triggered the emergence of the Socio-Technical approach (Mumford, 2006) that becomes an increasingly popular design conceptual framework for examining and changing the workplace environment over the last decades (van Eijnatten, 1992).
In contrast to the techno-centric perspective that exclusively focuses on technology, the Socio-Technical approach also focuses on people (Rice, 1958), and it considers that technological instruments (hardware) affect workers behavior through the organization and the work planning (software), and it proposes that there are several possibilities to carry out this work planning (Peiró, 1991).This theory considers every organization to be made up of the social (i.e., the people), the technical (e.g., the tools, techniques and knowledge people use to produce a product or a service), and the environmental (e.g., the users of the product) subsystems, the compatibility  (Lindenberg & Steg, 2007).Environmental knowledge is also a significant predictor of ecological behavior intention that, in turn, predicts general ecological behavior (Kaiser, Wolfing, & Fuhrer, 1996).Information about energy-saving options in the building influence also energy-related office user behavior (Brown & Cole, 2009).Simultaneously, behavioral change can sometimes take place through economic instruments such as incentives (Owens & Driffill, 2008) offered by the organization.
Finally, in line with the demand-control model of occupa-tional stress (Karasek, 1979), the perception of control (e.g., over different environmental characteristics in the office such as air temperature, noise, outside view, and lighting) is con-sidered an important job resource that may help employees to deal with demands (Vischer, 2007).There is vast literature that shows that employees' control over their physical envi-ronment is beneficial for their well-being and performance (e.g., Boyce et Dolan, 2009).Simultaneously, job performance can be operation-alized as including different facets, such as in-role performance (intrinsically related to the activities included in the job description), extra-role performance (behaviors that are not directly related to the tasks included in the job descrip-tion), and creative performance (carrying out activities that are both creative and useful for the organization).Increased well-being and performance can both be beneficial for the whole organization since they may lead to economic gains.

BrINgINg SOCIO-TECHNICAL ApprOACH INTO prACTICE: THE SSO IEQ mOdEL
The SSO project is grounded in the socio-technical approach as it proposes that it is necessary to take into account the active role and the psychosocial aspects of the office users.In this way, the SSO project aims at providing better performance than a conventional office or one in which technology has been introduced from a deterministic perspective.In order to do it, the SSO model allows for a greater chance of introducing technology-related changes in the organization, taking into account the psychosocial characteristics of the office users, as well as by optimizing their well-being and performance.
The conceptual model of the SSO project is depicted in the Figure 1.
First, the SSO model considers that, according to previous studies, some factors of the office design used in smart and sustainable offices may positively affect health and wellbeing (e.g., DeCroon, Sluiter, Kuijer, Frings-Dresen,2005; among which determines the success of an enterprise (Pasmore, 1995).
It is important to highlight that, although in some occasions technology imposes a specific social organization, in general terms, and according to the concept of equifinality, there are always more than one way of adopting and implementing a technological solution.Along these lines, it is key to choose the most adequate psychosocial alternative of organization to ensure increased workers' productivity and satisfaction (Peiró, 1991).The Trist and Bamforth's (1951) studies in the British coal mining industry provide a vivid example of the impact of equifinality.These studies describe the situation in the mines where, keeping up with the technology development, coal extraction methods were introduced.The improvement included specifically for he replacement of the hand got method by the longwall method.Despite the technological improvements, in some mines, performance of the miners decreased and the workers expressed complaints about the new work organization, the separation of the existing groups of workers and the disintegration of the work cycle and of the control of the workers in the arrangements to carry on their work, increased conflicts and absenteeism, clearly indicating the workers' preference for the previous system.In contrast, smaller mines did not show these kind of problems.
The difference consisted of the fact that the smaller mines introduced the new method but, in contrast to what the bigger mines did, considered and maintained a number of previous human and social features of the work in the workplace.According to different studies, the fact of taking into account both social and technological dimension by considering the existing traditions in the mines ensured the success of the new method (Peiró, 1991).In conclusion, the extent to which labor organization considers social factors and makes them compatible with the new requirements imposed by technological dimensions is likely to determine the success of the organization (Peiró, 1991).All this makes the socio-technical perspective an adequate approach for introducing technological changes, since it highlights that, although technology and organizational structures may change, the employees' rights and needs must be given as a priority, and given that an important socio-technical value is democracy, as it encourages employees' participation, influence, and decision-taking on the issues that concern them.

SOmE pSyCHO-SOCIAL dETErmINANTS Of SUSTAINABLE BEHAvIOr
Following the socio-technical approach, in order to take the most benefit from the technology introduced in the organizations (e.g., oriented at diminishing energy consumption), it is key to focus on the worker.Indeed, such outcomes as decreased energy consumption may depend heavily on office users' behaviors that can be shaped by different psychological factors, some of which can be attitudes, perceived self-efficacy, knowledge, goal conflicts, or incentives.In this way, there can be several determinants of efficient or inefficient energy-related user behavior in office buildings.First eral scales such as sustainable behaviour, reasons for sustainable behaviour, perception of environmental stressors, well-being (hedonic and eudaimonic), occurrence of healthrelated symptoms, and performance (in-role, extra-role, and creative).In the following section, we will describe the scales comprised in the survey questionnaire.

Sustainable Behaviour
The sustainable behaviour scale takes into account different aspects of sustainable behavior, such as: a) Use of personal electronic devices brought to the workplace (e.  2012), α = .79.We also control for the use of special clothing and/or earplugs, using 3 items elaborated by the research team).

reasons for Energy-related Behaviour
This scale was developed by Windlinger et al. (2012) and it includes 6 aspects of occupant behavior relevant for energy consumption and sustainable behaviour, such as: a) Energy-consumption habits that refer to being conscious of the consequences of ones' energy-related actions versus uninten-Vilnai-Yavetz, Rafaeli, & Yaacov, 2005).In turn, improving health and wellbeing in the office (e.g., job satisfaction, work engagement) may result in productivity gains (e.g., increased individual and team performance and decreased absenteeism), producing economic benefits for the organization.
Second, the SSO model considers that the energy efficient behaviors because of an appropriate usage of sustainable technological solutions will depend on users' values, attitudes, habits, knowledge, perception of control, and perception of self-efficacy regarding energy saving.The SSO IEQ model takes into consideration that people interacting with technology in their offices, have margin of action, and do not lose their control.
Finally, the SSO project proposes that contributing to the sustainability of the office by reducing energy consumption will not necessarily lead to decreased comfort for the office users.If this decoupling between energy consumption and comfort occurs, organizations will be able to take benefit from lower energy costs, as well as from increased well-being and performance of the office users that will lead to greater organizational gains.

Occurrence of Health-related Symptoms
This scale measures the existence of health symptoms (e.g., respiratory problems, headaches, difficulties concentrating) due to one's work environment.It is composed of a list of 10 symptoms adapted from Anderson (1998).The global score a α is .92.

In-role performance
This scale measures the extent to which an employee carries out tasks that are expected from him/her in his/her job.It is composed by 3-items reformulated from the scales by Mackenzie, Podsakoff and Podsakoff (2011) and by Williams and Anderson (1991), α = .79.

Extra-role performance
With this tool we aim to measure the extent to which an employee carries out tasks that are not directly requested from him/her (extra-role performance).To do so, we use a 3-item scale constructed on the basis of items proposed by Mackenzie, Podsakoff and Podsakoff (2011) and by Williams and Anderson (1991), α = .78.

Creative performance
This scale measures the extent to which an employee perceives himself/herself as original and practical at work, as a person that develops creative ideas, methods or products that are novel and useful for the organization.Creative performance is measured with a 3-item scale developed by Oldham and Cumminngs in 1996 with α = .84.

CONCLUSIONS
In the present technical note, we have discussed the importance of a socio-technical approach to ensure an adequate adoption and use of technological advances oriented at reducing energy consumption.This approach emphasizes that psychsocial aspects of the users individually and collectively is key to obtain the machine-human fit when modifying the environment to maximize the opportunities for introducing sustainable solutions and changes in organizations oriented at decreasing energy consumption.As such, different psychological determinants of energy-related behaviors in office buildings can include: attitudes, perceived self-efficacy, knowledge, goal conflicts, incentives, or perception of control.
In the present work, we have described the main assumptions of the SSO project.We have explained that the SSO project considers as key the link between innovative and sustainable building systems and technologies with improved IEQ involves human factor at work.Also, we have presented the method used in the SSO project to evaluate the psychosocial phenomena considered in the model.The information obtained may help to improve the process of implementation of sustainable technology and solutions in office buildings.
Also, in the SSO project we propose that contributing to the sustainability of the office by cutting energy costs will not necessarily lead to decreased well-being and performance of tional energy waste (1 item); b) Users' knowledge on energy efficient behaviour in office buildings that includes information about energy-saving opportunities exhibited in the employee's capability of indicating effective actions to reduce energy consumption as well as in his/her perception of the quantity of information provided in the company about the opportunities to save energy (α = .71);c) Attitudes toward saving energy that refer to consideration of energy conservation as useful, desirable, and compatible with goals to be carried out at work (α = .61);d) Self-efficacy regarding energy saving behavior (1 item); e) incentives regarding energy conservations (α = .71);and f) Goal-conflicts (α = .81).

perception of Environmental Stressors
This scale refers to user's perception of the existence of physical stressors in the work environment such as room temperature too high, office temperature too low, draught, noise, unpleasant odour, etc.This scale is composed of a list of 11-items based on Anderson (1998) and has α = .80.

Hedonic Well-Being
Hedonic well-being scale is composed of 5 sub-scales that refer to different aspects of the construct such as: a) Job satisfaction that refers to the extent to which a person is satisfied with both intrinsic (e.g., task variety at work) and extrinsic (e.g., salary) aspects of his/her job.(2004) and has α = .83.

Eudaimonic Well-Being
In this project we measure eudaimonic well-being using the following scales: a) Purpose in life and personal growth.This scale was developed by Ryff (1989)  be optimized using appropriate design, and, as a result, help the organizations to build innovative workplaces that support employees' well-being and productivity.

the office users.This decoupling will allow the organizations to take benefit from lower energy costs, as well as from increased well-being and performance of the office users that will lead to greater organizational gains.
To conclude, SSO project aims to promote an appropriate and sustainable usage of technology by acknowledging the central role of office users in sustainable offices.To this aim, it proposes a sustainable office assessment tool that can support the planning as well as decision-making process during the design and implementation of new offices or for retrofitting existing ones.This assessment tool can help to diagnose the possibilities for improvement in the IEQ that could rEfErENCES g., fan, heater), measured with an 8-item scale developed by Windlinger et al.
