Paper accepted for eceee 2017 Summer Study on Energy Efficiency

A paper co-authored by the Centre's Professor David Wallom and Research Associate Ramon Granell has been accepted for the eceee 2017 Summer Study on Energy Efficiency.

The paper*, written in collaboration with University of Oxford colleagues from the Environmental Change Institute and the Law Faculty, examines the impact of green leasing on energy use in a retail portfolio and the limits to big data analytics.

The retail sector is a major consumer of energy - buildings in the commercial sector overall are estimated to be responsible for 10% of the UK's greenhouse gas emissions (WSBF & Carbon Connect 2013). Many large retailers are willing to make efficiency measures.

However, more than half of properties in the commercial sector are rented rather than owned, which can hamper the implementation of energy and carbon saving technologies by the occupier. Many of the larger and more impactful energy efficiency measures require active collaboration between the owner and tenant for successful implementation, possibly requiring changes to either the building fabric or plant/equipment. Property leases may prohibit such changes, or the sharing of implementation costs may prove contentious.

The paper explores some of the new mechanisms which have been developed aiming to overcome this barrier, namely 'environmentally conscious' legal agreements (MoU) between parties with existing tenancy agreements; or through clauses specifying how to collaborate directly inserted into new lease agreements (so called 'Green Leases'). The paper aims to determine whether there are actual and quantifiable benefits from the use of these mechanisms.

Using data from a large UK retail chain, the authors have investigated, using a number of different analytical methods, how energy consumption changes after the introduction of an MoU or Green Lease. The study is one of the first attempts at using analytics to investigate the effect of the introduction of green clauses in property arrangements over real data of a significant portfolio of establishments of the same organisation.

The Summer Study, taking place from 29 May – 3 June 2017 in France, is a biennial, interdisciplinary, cross-sectoral conference which gathers 450 energy efficiency professionals to explore and expand the evidence and intricacies of energy efficiency. The Summer Studies are the backbone of eceee's ambition to deliver comprehensive evidence-based information on all aspects of energy efficiency.

This year's theme, Consumption, efficiency & limits, is focused on exploring the critical elements and foundations of a sustainable society that addresses sufficiency and limits.
