UNLOCKING ENERGY EFFICIENCY IN COMMERCIAL BUILDINGS
Leasing Strategies Commercial Tenants Can Take to Make Buildings Energy Efficient

OBJECTIVES
1. To clearly identify the nature of the “split incentive” in commercial leasing.
2. To show in economic terms how the split incentive inhibits building retrofits.
3. To explain how to fix the split incentive.
4. To convey the importance of measurement and verification for purposes of fairness and building efficiency.
5. To establish the benefits for tenants of adjusting traditional approaches to capital and operating costs in commercial leasing.

The most important factor affecting efficiency is who pays for it.
Full service gross
Modified gross Net lease
Owner pays for all core building operating and capital expenses.
Owner pays for capital and a “pool” of operating expenses.
Tenant pays all increases in the pool after the first year of the lease.
Tenant pays base rent and all operating costs defined in the lease, and may or may not pay for capital improvements.

In modified gross leases, tenants pay for a pool of core building operations as they exceed Year 1 of the lease.

If “modified gross” with a base year is unavoidable, lease must adjust capital recovery.
Operating Expenditure Clause
1. Additional rent may include amortization of capital items that save operating costs.
2. Amortization can bundle cost and savings of retrofit items (i.e. will notfollow GAAP “useful life” method).
3. Landlord may amortize the expense in an amount equal to total savings.

Retrofit may prevent rising usage and repair costs from increasing “Additional Rent” to the tenant.
Retrofit arrests rising cost of declining systems
Annual Operating Costs

A good retrofit leads to better tenant comfort and operations.
• New technologies allow better control over temperature
• Fewer hot/cold callsTemperature
• New central building systems allow integration with tenant systems for smoother operations
Systems Integration
• Fixing inadequate building ventilation improving fresh air flow and tenant health

In return, tenants should expect reports on success of energy efficiency – they helped pay for it.
What is being expensed to me?
• An absence!
• LACK of energy use
What does that mean?
• Have to assess a counterfactual
• What would have happened if there were no retrofit
How do I do that?
• Compare real energy usage data from before and after
• Adjust for weather, occupancy

Not all measurement methods are created equal.
• Measurement using manufacturer’s specifications (stipulated savings)A
• Measurement of new equipment operation in isolation from rest of building systems.
B• Measurement based on comparison
of actual “before and after” bills to reflect interactivity.
C
D • Savings measured based on actual “after” bills and a simulated “before.”

Leases should require disclosure of overall building resource use and ENERGYSTAR score.

Apply these three principles.
1.Landlord should operate the building and tenant its premises as efficiently as is feasible.
2.Responsibility for capital expense and benefit of savings should reside with the same entity.
3.Consumption and demand for resources throughout the building should be measurable and transparent to both Landlord and Tenant
All of the savings from a system improvement should be available to pay for the improvement

What can you do now?
1. Get buy-in from senior leadership to apply these principles.
2. Look for opportunities to change leasing approaches – upcoming renewals, new leases.
3. Ensure the term sheet for new space specifically calls out capital recovery equal to savings.
4. Consider adjusting an existing lease for these issues alone.

OBJECTIVES
1. To clearly identify the nature of the “split incentive” in commercial leasing.
2. To show in economic terms how the split incentive inhibits building retrofits.
3. To explain how to fix the split incentive.
4. To convey the importance of measurement and verification for purposes of fairness and building efficiency.
5. To establish the benefits for tenants of adjusting traditional approaches to capital and operating costs in commercial leasing.
