DOC’s senior leadership dedicates resources and tools to measure and manage resource consumption, including energy, water, and waste. We are deeply committed to implementing practices and transparently reporting on our results as we work to meet and exceed our benchmarks.

In everything we do, our team is dedicated to developing, owning, and managing a portfolio of buildings that maximizes our health care partners’ comfort, health, and success through fiscally responsible ESG practices.

Benchmarking & Methodology

We established the following criteria to select properties for our inaugural ESG report:


owned as of January 2018 to determine year-over-year utility spend


multi-tenant properties with readily accessible data to create a like-for-like comparison


buildings over 25,000 SF to maximize ESG impact

We have focused our initial report on 70 multi-tenant properties in which we have property management services in place and utility information available. These 70 properties represent 4.49M square feet, or 32% of our entire portfolio.

This inaugural report represents the benchmarking and reporting on building performance as of January 1, 2018 to develop our three-year ESG plan. Based on this data, our team set 10% reduction targets in energy, emissions, and water consumption, and a 10% waste diversion rate increase for 2019-2021. This report reflects the inaugural year-over-year performance data.

While the data for this inaugural report stems from our identified subset of properties, our commitment to advancing sustainability projects spans our entire portfolio. When DOC identifies properties with opportunities for improvement, we optimize existing systems and allocate capital resources for upgrades. Additionally, we continuously engage property management in the process of evaluating no- or low-cost efficiency opportunities through an annual sustainability self-assessment, providing visibility of building-level data, and empowering these team members to help achieve our ESG goals.

The identified portfolio, alongside all DOC-owned assets, are tracked in software systems such as ENGIE, ENERGY STAR® Portfolio Manager, and Measurabl to monitor energy, water, and waste, leveraging this data to prioritize our capital efforts.

2020 Earth Day initiative

DOC’s 2020 Earth Day initiative, Water Smarter, spotlights water conservation through two approaches: (1) health care partner education and (2) property management research and mitigation. The health care partner program provided water reduction strategies at work and at home. Our property management and engineering teams conducted water usage audits to target and repair leaky faucets, install low-flow devices, and add rain sensors on watering systems.

Spotlight On:

National Recycling Platform

In 2019, DOC increased our waste data collection by initiating a national waste management contract. We also established a waste policy to govern our program across the portfolio. In 2020, all of DOC’s property managers will receive comprehensive training on best practices in waste management at medical office buildings.

Capital Investment Strategies

The company has developed a strategic, sustainability-focused capital expenditure (CapEx) plan concentrating on projects with the most significant environmental and financial returns. This focus is key to achieving our ESG goals as we work to increase our operational efficiency. The benefits are clear, as The World Green Building Council estimates that green retrofits decrease annual operating costs by an average of 9%.

In 2019, DOC invested $3.4 million in ESG-driven capital improvements across 50 properties. Asset-level efficiency projects are identified based on a variety of factors, including committed capital, size, and location of the asset, as well as the projected return on investment.

Sustainable Finishes

To maximize the usage of sustainable materials during tenant buildouts and common area projects, DOC worked with national architecture and interior design partners to develop a standard finish program including paint, flooring, lighting fixtures, and window treatments. All materials meet high-performance benchmarks for sustainability. In addition to these benefits, these standard finishes include access to negotiated national pricing discounts, representing green cost savings.

Building Automation System (BAS) Optimizations

In 2019, DOC completed a comprehensive Building Automation System (BAS) optimization program at eleven properties. This exercise identified cost- and resource-saving opportunities related to indoor climate management, lighting schedules, and mechanical performance. As part of this program, facility engineers received training on how to analyze energy profiles and adapt programming based upon criteria such as occupancy and weather.

Recognizing Excellence

At a property level, our partners are a vital part of ESG success. In 2019, DOC established a program to recognize individual sustainability efforts on a quarterly basis. This Sustainability Award recognizes management personnel, service technicians, building engineers, and vendors based on their outstanding work in sustainability that aligns with our ESG goals.


IREM® CSP Designation

The Institute for Real Estate Management® (IREM) Certified Sustainable Property (CSP) is a sustainability certification program that focuses on the role of exceptional real estate management through green building performance. IREM’s sustainability certification provides properties with recognition for resource efficiency and environmental initiatives. To earn this certification, each property must meet baseline requirements and then earn necessary points across energy, water, health, recycling, and purchasing categories.

DOC earned eight IREM® CSP certifications in 2019 and plans to complete 20 new certifications by 2022.

IMT Green Lease Leaders Gold Designation

Green leases, also known as “high-performance” or “energy-aligned” leases, create win-win strategies for building owners and tenants by equitably aligning the costs and benefits of energy and water efficiency investments for both parties. Where conventional leases tend to make energy efficiency the sole responsibility of the landlord, under a green lease, tenants and property owners coordinate to conserve resources and align the costs of sustainable investments.

In 2020, DOC earned the Green Lease Leaders Gold Designation from the Institute for Market Transformation (IMT) and U.S. Department of Energy (DOE) Better Buildings Alliance. Green Lease Leaders is the premier industry recognition program that spotlights forward-thinking real estate companies who utilize the leasing process to spur collaborative action on energy efficiency and sustainability in buildings.

To receive Green Lease Leaders’ recognition, organizations must meet prerequisites and demonstrate best practices. Criteria include utility data tracking and sharing, cost recovery for efficiency-related capital improvements, sustainability training, and energy efficiency fit-out requirements for tenant spaces.
