This paper aims to investigate the drivers and barriers for green leases and tenancies in sustainable “Building Research Establishment Environmental Assessment Method” (BREEAM) and “Leadership in Energy and Environmental Design” (LEED) certified office and office buildings in Norway, the UK and the USA. This study focuses on the differing perspectives between owners and tenants. It is then considered as to how these issues are dealt with during different phases of a buildings life cycle. This research is based on existing literature and semi-structured interviews that studied qualitative and quantitative elements in the context of ownership and tenancy of single and multi-tenanted sustainable office buildings.,Using a mixed-method approach involving semi-structured interviews with both qualitative and quantitative elements along with desk research, this paper evaluates how green leases and tenancies in offices and office buildings that are BREEAM and LEED certified require a reconsideration and re-evaluation of the acquisition, operation and disposal of office buildings by building owners and their tenants. These stakeholder relationships are supported theoretically using a theoretical model that outlines the interrelation between the sustainable building and the relationships of the building owner, the user and the FM service provider.,The data gathered from the interviews justify and partly contradict some of the statements within existing literature, diminishing the importance of cost and the barrier of split incentive but instead illuminate the importance of less tangible considerations such as company policy or a sustainability strategy. The results also note the realisation of a changing market for commercial real estate driven by the sustainable business needs of tenants for the occupation of workspaces.,These findings have the potential to further develop theories and provide an insight into how the relationships between actors from a business, procurement and contractual perspective need to be developed to ensure more proactive development of green leasing of new and existing sustainable office buildings, along with where strategic attention is required during the building design, construction, operational and use phases.,This paper is based on original research through interviews and literature studies supported by an existing theoretical model. The results have been partly presented and initially discussed at the WBC World Congress 2016 in Tampere, Finland.

商业房地产的绿色租赁

本文旨在研究在挪威，英国和美国的可持续“建筑研究机构环境评估方法”（BREEAM）和“能源与环境设计领导力”（LEED）认证的办公楼和办公楼中绿色租赁和租赁的驱动因素和障碍。美国。这项研究侧重于业主和租户之间的不同观点。然后考虑在建筑物生命周期的不同阶段如何处理这些问题。本研究基于现有文献和半结构化访谈，这些研究在单租户和多租户可持续办公楼的所有权和租赁范围内研究了定性和定量要素。采用混合方法，将半结构化访谈与定性两种方法结合在一起和定量元素以及案头研究，本文评估了获得BREEAM和LEED认证的办公楼和办公楼中的绿色租赁和租赁如何要求建筑物所有者及其租户重新考虑和重新评估办公楼的购置，运营和处置。这些利益相关者之间的关系在理论上得到了支持，该模型概述了可持续建筑与建筑物所有者，用户和FM服务提供商之间的关系。从访谈中收集的数据证明并部分抵触了内部的某些说法。现有文献减少了成本的重要性和分散激励的壁垒，但反而说明了诸如公司政策或可持续性战略等不太实际的考虑的重要性。结果还表明，由于租户对工作空间的占用的可持续业务需求所驱动，商业房地产市场正在发生变化。这些发现有可能进一步发展理论并提供洞察力，说明参与者之间的关系如何。需要发展业务，采购和合同的角度，以确保更积极地发展新的和现有的可持续办公建筑的绿色租赁，以及在建筑设计，建造，运营和使用阶段需要战略关注的地方。在现有理论模型的支持下，通过访谈和文献研究对原始研究进行研究。结果已在芬兰坦佩雷的2016年WBC世界代表大会上进行了部分介绍和初步讨论。
