Scope Of Work

Zero Energy Engineering for Our Boys in Blue

CMTA was proud to partner with the Cincinnati Police Department on their -new District 3 Police Headquarters. We were able to exceed their efficiency and sustainability goals without additional funding from the city, and create a Zero Energy police headquarters on a traditional budget.

THE CHALLENGES

Zero Energy for a 365/24/7 mission critical facility

Embracing the city's past sustainable success and raising the bar

Delivering the project within budget

THE SOLUTIONS

In an effort to help the Cincinnati Police Department meet these challenges,CMTA used the First 30 process to ensure exceptional results. Our dynamic internal team challenged ourselves to find creative solutions early in the process. A "charette" format was used with all stakeholders early in the design process. One charette outcome was to set energy goals that were further expanded to set sub-goals for the HVAC system, lighting, water heating and plug load energy consumption. These goals are integrated into all decisions from that point. Participants of the charette included the design team, occupants, facility operators, janitorial staff, IT staff, etc. We brainstormed ideas to achieve the sustainability and energy goals while meeting all functional requirements of the building.

To support the charette energy goal, we look researched data bases such as CBECS, ASHRAE 90.1 and . The facility's energy goal was set at 35.3 kBtu/sf-yr at the charette. The building included a power monitoring system so actual end-use energy consumption could be measured. The industry is plagued with buildings that are modeled to perform efficiently, but once built and measured, significantly miss their energy goal.

This project included both MEP and building envelope commissioning with a building air pressure test to minimize air infiltration. The goal being to insure all systems are installed correctly, operating as intended and temperature/occupancy set-points are correct. The site was designed to include bio swales and filtration swales to reduce the quantity of water, and partially clean it, prior to entering the combined sewer system to address EPA deficiencies.
