We are committed to appropriate environmental stewardship, monitoring the performance of our responsible investments and measuring our progress toward improving the environmental footprint of our properties through the implementation of targeted environmental efficiency projects and equipment upgrades such as such as photovoltaic systems, LED lighting and higher efficiency HVAC systems. We seek to partner with our tenants to improve the efficiency of their leased space, decrease their resource consumption and increase the value of and return on our properties. These savings initially accrue to the tenants under our triple-net leases but also make our buildings more competitive and attractive to potential tenants when exposed to market conditions in future lease negotiations. In addition, when one of our buildings becomes vacant, we advance our cost-saving modernization efforts on our own initiative.
We are a growth-oriented company, and much of our growth is external, from acquisitions. Accordingly, we believe our environmental strategies are most effective if they influence how we price and purchase a building, rather than being restricted to incremental improvement of already-owned real estate. We employ responsible investing practices as part of our acquisitions due diligence process. Where feasible, in considering potential acquisitions, we evaluate and underwrite building systems, equipment and technologies that improve efficiency and conserve natural resources.
