2015 Sustainability Report Overview Intro What We Do Economic Environmental Community page 4 A Letter From Steve Melink, CEO

Welcome to the Melink Sustainability Report. We are proud to be a pioneer and leader in clean energy solutions for the commercial building industry. Serving as an example for our customers, industry, and community has been the best business decision we ever made. Melink started almost 30 years ago as an HVAC testing & balancing firm. As a direct result of this work, we invented energy-saving controls. Years later we also started a solar PV project development business. And geothermal HVAC is now our fourth business.

But our sustainability journey did not start in earnest until about 10 years ago. Inspired at a green building conference, we decided to design/build the first LEED Gold building in Ohio for our headquarters. Since then it has been upgraded to LEED Platinum and Net-Zero Energy (NZE) status. We knew we could and should do more, however. So we invested in a fleet of hybrid cars for our technicians and incentives for our office employees to buy either hybrid or electric cars. Today, over 50% of our employees drive alternative fuel vehicles to further promote our mission and brand.

The combined energy savings amount to over $50,000 per year. But the bigger advantage of our journey has been the HR and PR benefits. We are now able to attract and retain more talented employees than ever before by providing a healthier and more productive working environment. Steve Melink, CEO of Melink Corp. We are also able to attract and retain larger and more successful customers since they are increasingly selecting partners and suppliers who are aligned with their own mission and values. And make no mistake: sustainability is becoming a corporate value that America and the whole world is embracing.

The net result is Melink has gained a long term strategic competitive advantage. Our costs and risks are lower, our people are more committed and productive, and our sales have grown dramatically. And this has also allowed us to expand our customer offerings to make an even bigger difference going forward.

As we continue growing and more employees plug into our EV charging stations, maintaining our NZE status will require adding more renewables to our super-green headquarters over time. Therefore, we are planning to install another 50+KW of solar PV in 2015 to offset increased electric loads.

Success requires constant vigilance. But we are determined to exercise such vigilance and continue serving as a leader in the clean energy revolution. We believe this will help make the world a better place. Please let me know if you have any questions or would like to visit us for a tour!

Home Office

The 31,237 sq. ft Melink Home is LEED Platinum-certified and Net-Zero Energy. It is the cumlination of curiousity in environmentally friendly technology. Seeing our building as a green laboratory, we’re always drumming up ideas for our next experiment. We maintain a balance of solutions that are focused on renewable energy, energy efficiency, and energy conservation. Here we present the performance of some of our technologies. For a comprehensive list of our building’s green features, see Appendix A.

Heating & Cooling

2014 Geothermal Energy Transfer at Melink HQ Geothermal 100,000 Melink uses 28 geothermal wells to heat and cool the building, with over 5 miles of underground piping. The total geothermal energy for 2014 was 616,711 kWh - 78% used for heating and 21% 80,000 for cooling.

2015 Sustainability Report Overview Intro What We Do Economic Environmental Community page 12 & Monitoring Software

We monitor our power usage via an electrical distribution system, which includes sub-meters for each section of the building to allow separate monitoring of HVAC, lighting, and plug loads. Monitoring also includes trending of key building health parameters like temperature, CO₂, lighting levels, geothermal water temperature, and flow-rates.

Our talented engineers and developers have custom-built a monitoring software platform named MPower. We display MPower on a monitor in our lobby that allows users to view building loads down to the circuit level, and to empower them to find their biggest opportunities to save energy. Easily adaptable to existing building management systems (BMS), MPower allows users to verify reduction in loads both short and long-term and has alert functions to notify of excursions beyond pre-set parameters. It also integrates renewable energy data to show a net MPower allows us to energy usage (renewable energy generation/offset minus the total load). MPower is used to help us achieve net-zero energy status and allows us to compare production of all of our solar PV monitor our electric loads & systems on an equal footing. It adjusts for differences in system size and orientation to the sun generation in real-time using the latest in sensing technology.

Water Conservation

At Melink, we use several water conserving technologies. These include our automated sink faucets in all bathrooms and waterless urinals in all men’s restrooms.
