Green lease clauses are the provisions that decide who measures, who pays for and who benefits from a building’s environmental performance. They exist because of a simple mismatch. The party that can cut consumption and the party that pays for the equipment are usually not the same party. A landlord owns the roof and the plant. A tenant pays the energy bill. Standard drafting leaves each side with the cost but not the benefit, or the control but not the incentive. In Slovak industrial leases the decisive clause is rarely the aspirational cooperation wording that most drafts lead with. It is the metering clause.
What a green lease clause actually is
It is ordinary lease drafting applied to energy, water, waste and data. The reference document most European landlords and their lawyers work from is the Green Lease Toolkit published by the Better Buildings Partnership. It sets out ten areas it expects a lease to cover: cooperation between the parties, a building management or sustainability group, sustainable use of the premises, data sharing and metering, extending the landlord’s rights to carry out works, the tenant’s alterations, energy performance certificates, waste on both sides, reinstatement at yield up, and renewable energy. The toolkit frames the purpose plainly. Through carefully considered lease obligations, it says, landlords and tenants can hold each other to account for improving the environmental performance of buildings. Nothing in that list is exotic. Every item is a variation of a clause the lease already contains, rewritten so that environmental outcomes have an owner. The toolkit also grades its drafting in shades. There are light, medium and dark green versions of each clause, chosen according to how far each party actually intends to go. That grading is the most useful part of it, because it turns a yes-or-no argument into a negotiation over degree.
The problem these clauses exist to solve
The split incentive, which is easier to see in an industrial building than anywhere else. The landlord owns the roof, the envelope, the lighting and the heating plant. The tenant pays the electricity bill and runs the operation that generates the consumption. If the landlord upgrades the lighting or insulates the roof, the tenant banks the saving and the landlord banks the invoice. If the tenant installs efficient equipment or changes shift patterns, the benefit disappears at the end of the term along with the alterations. Neither side is being unreasonable: each is responding rationally to a contract that gives them the cost without the benefit, or the benefit without control. Sustainability clauses are the mechanism for redistributing that. A works clause can let the landlord improve the building mid-term. A cost-recovery mechanism can share the saving. A data clause can make consumption visible to both parties, which is the precondition for any of it. Without that redistribution, both sides can hold genuine environmental targets and still do nothing, because the building sits between them.
Why Slovak cost structures make metering the priority
Because of how operating costs are usually allocated here. DLA Piper’s Slovak guidance describes the standard arrangement. The landlord covers the operating costs of the whole building, and the tenant pays a proportion of those costs calculated according to the size of the leased premises. The same applies to utilities: the cost of energy, water and sewage is generally paid by the landlord, with the tenant paying a proportion worked out the same way. Read that twice and the consequence is uncomfortable. Where energy is split by floor area rather than by consumption, a tenant who invests in efficiency subsidises the neighbour who does not. A tenant who wastes energy is partly paid for by everyone else in the park. The best toolkit in the world cannot survive that arithmetic. Sub-metering is therefore the first clause to fix in a Slovak industrial building, together with a service charge that follows the meter rather than the square metre. Everything else in the clause set assumes it. That is also why the data sharing item is not housekeeping. Without separate meters there is no data to share, and the reporting duties arriving through corporate ESG frameworks land on a tenant who cannot answer them.
The alterations trap in Slovak leases
The second Slovak point sits in the consent regime, and it catches exactly the tenant who wants to act. DLA Piper is explicit here. The landlord’s consent is required before any changes are made to the property. Without it, the tenant must restore the property to its original condition at the end of the lease. Where consent was given, the tenant may claim reimbursement or the increase in value. Now apply that to an occupier who fits LED lighting, adds roof insulation, installs a heat pump or puts panels on a roof they do not own. Without written consent that names the works and lifts the reinstatement duty for them, the tenant has bought an asset they must later remove at their own cost. The improvement leaves the building with them. This is where the alterations and reinstatement clauses earn their place. Not as statements of intent, but as a carve-out: efficiency works are consented, they stay at expiry, and they are not reinstated. Whether the tenant is paid for the residual value is a separate argument. The moment to have it is before signature, while the reinstatement wording is still open.
How to negotiate the clause set in practice
In the right order, at the right moment, and with a realistic view of who holds the pen. Order first. Start with sub-metering and the service charge apportionment. Then the alterations and reinstatement carve-out for efficiency works. Then rights and cost-sharing for landlord improvements mid-term. Then data sharing. The softer cooperation and management-group wording comes last, because it binds nobody, and most drafts lead with it. Moment second: all of it belongs in the heads of terms. A clause about who pays for a roof upgrade in year six is priced into the deal, and a lease already at the second draft has hardened around a rent that assumed nothing of the kind. Bargaining position third, and this is the part occupiers underuse. The Cushman and Wakefield MarketBeat for the first quarter of 2026 puts Slovak vacancy at 7.72 per cent and expects it to settle near 8 per cent. Prime rent has softened to EUR 5.30 per square metre per month. There are 203,200 square metres under construction at only 35 per cent pre-let, and renegotiations run at 54 per cent of demand. The report calls the market tenant-favourable. A tenant negotiating in those conditions can ask for meters and a reinstatement carve-out and expect to get them. The same request during a supply squeeze is a conversation the tenant loses.
Frequently Asked Questions
Does a green lease clause increase the rent?
Not directly, and the ones that matter most cost the landlord very little. Sub-metering is a capital item measured in thousands, not a rent driver. Clauses that oblige the landlord to spend real money mid-term, such as an obligation to upgrade plant to a target, are the ones that get priced, which is why cost-sharing wording usually replaces a bare obligation.
Is a green lease the same as a certified building?
No. A certificate rates the building and is issued by an assessor. Environmental lease provisions allocate behaviour and cost between two parties for the term of the contract. A certified building can sit under a lease that gives neither side any obligation, and a plain warehouse can sit under drafting that makes both sides measure and improve.
What is the single most useful clause in an industrial lease?
Separate metering of energy and water for the demised premises, with the service charge following consumption rather than floor area. It converts every other environmental provision from aspiration into arithmetic, and it is the clause a Slovak standard cost structure most often lacks.
Can a tenant install solar panels under a standard Slovak lease?
Not safely. Roof rights usually stay with the landlord, and Slovak law requires the landlord’s written consent for changes to the property, failing which the tenant restores the original condition at the end of the term. Panels, the roof lease and the fate of the generated power all need express wording.
