What you need to know about Green Leases

A Green Lease is a commercial lease, containing additional clauses that the building must be occupied, operated and managed in an environmentally sustainable manner. The concept of a Green Lease was first developed in Australia where its use has been mandatory since 2006 in all government-owned and occupied buildings. In France, Green Lease legislation has been mandatory since 2013. Globally, 42% of investors have Green Lease clauses in place with an additional 37% looking to adopt them by 2025. On the occupational side, 34% of occupiers are currently committed to Green Leases.
Green Lease clauses can range from ‘light green’ to ‘dark green’ depending on the nature of the property, and energy performance certifications. The essential elements of a Green Lease include:
- Agreement by Owner and Occupier not to do anything which would adversely affect the Building Energy Rating of the building. Any works to be carried out including fit-outs are carried out to a measurable standard such as BREEAM or LEED.
- Separate digital metering for utilities and central services so that Owner and Occupier can measure all outputs and agree to share respective data.
- Participation in a building management committee as a means of education and communication between the various Occupiers in the building with the Owner on the management of the building.
- Collaborative approach in relation to disputes on green issues and that those be dealt with by way of mediation.
For both Owners and Occupiers, a Green Lease encourages a relationship of collaboration and meets corporate social responsibility objectives.
What are the benefits of a Green Lease?
For the Owner
- Property investment is maintained in accordance with environmentally sustainable design.
- The building is more attractive to both Occupiers and Investors.
- Costs of maintaining the asset are minimised.
- With increased awareness and focus on sustainability by investors and occupiers, better sustainability credentials may impact a building’s marketability and value. Improved environmental credentials will attract the increasing number of Occupiers that focus on meeting their and their stakeholders’ ESG requirements. This creates a competitive market advantage over alternative properties which do not meet the same standards.
- Green Leases will assist Owners to meet existing and future environmental regulations.
For the Occupier
- Reduced operating costs in the occupation of an energy-efficient building for things such as electricity, HVAC and water.
- Owners may offer incentives to Occupiers who exceed energy efficiency targets.
- Studies have shown links between environmentally sustainable workplaces and increased employee productivity and satisfaction.
- Occupying a green building can form part of a Occupier’s ESG requirements, which in turn can appeal to employees and help an Occupier to recruit and retain the best talent. For retail Occupiers, green stores can appeal to the environmentally conscious consumer
Green leasing provides an effective framework for both Owners and Occupiers to work together to achieve a common objective and comply with future legislative requirements. A sustainable building with lower running costs is more marketable for Owners and more cost-effective for Occupiers to occupy. Given the evolving nature of Green Leases, it is prudent to take legal and professional advice before entering such leases to ensure that the provisions are suitable for your organisation.

Bannon’s latest Office Pulse is now live!
Bannon’s latest monthly Retail Pulse has now gone live.


The first Bannon Dublin Office Market Pulse of 2023 is now live. Dublin office market take up exceeded 2,650,000 sq.ft. in 2022, boosted by a busy Q4 with over 804,000 sq.ft. transacting in the final quarter. See full details below together with expert insight from 




For the property sector, while one of strongest capital market years on record (second only to 2019), 2022 will be best remembered as the “year of reckoning”. A year where a mixture of macro-economic and geopolitical issues combined to commence rebasing the market following almost a decade of effectively zero interest rates, low inflation, and expansive monetary policies.


The first Bannon Pulse of 2023 is now live. We look back at the strong level of activity in 2022, highlighted by the large number of lettings and new market entrants. Our occupancy trackers finished 2022 in positive form, as did our trading analysis across the retail categories. 




Our final Retail Pulse of 2022 has just gone live. All in all, an exceptionally busy year for the team at Bannon. 2023 is looking very promising for Retail.
Bannon’s latest monthly Retail Pulse has now gone live. Neil Bannon looks at recent retail sales data to demonstrate how the negative narrative continues to clash with reality.




The Bannon Dublin Office Market report is available now. Take up for the third quarter reached 819,000 sq.ft. representing a 60% increase on Q2 and a 77% increase in the same period last year. Lease flexibility continues to be sought in the short term as companies continue to assess their office requirements as remote and hybrid models are fully determined.






Whatever the short balance of the year has in store, there is little doubt that in 2022 a rubicon was crossed for assets that are not scoring well with their ESG credentials. The RICS made sure valuers took the step to acknowledge the importance of ESG credentials on buildings and their impact on values with the publication of a new guidance note effective from January this year. Also in 2022, more than ever, both occupiers and owners made known their absolute preference for ESG compliant buildings. In the office sector in Q3 over 85% of city take-up related to ESG compliant offices.

The Croí Cónaithe scheme, which has had €450m earmarked for it over the next three years, is designed for the State to plug the gap between the cost of construction and the market value of apartments. It relates to certain areas where the sales price achievable is less than the costs of development.

Sustainability impacts everybody, whether it is investors securing the long-term value of their assets, corporate occupiers demonstrating their environmental credentials to clients and staff, retailers reacting to shifts in consumer demand or funding institutions protecting the security of their loan books. There is no part of the property market that is and will not be increasingly impacted by the move to a zero-carbon future. This realisation was the reason Bannon established EVIA 3 years ago; a consultancy business whose sole focus is the delivery of sustainable solutions to stakeholders in the commercial real estate sector. Since its inception EVIA, working hand in hand with the Bannon Management, Investment and Consultancy teams, has delivered dozens of sustainability projects including LED lighting projects, smart metres and energy monitoring, solar power installation and increasingly we are seeing demand from clients to provide an overarching strategy to put their entire relationship with real estate on a long-term sustainable footing.
