While at a prior firm, Dana led the following project (confidential client) from early brainstorming sessions through to final presentations to key stakeholders.

Comprehensive (cradle to gate) carbon footprint models were developed for four (4) of bio-pharmaceutical manufacturing processes.  The processes modeled were large and small scale, microbial and mammalian. Each set of calculations included carbon impacts from direct and indirect energy usage due to space conditioning equipment, process steam / chilled water, process equipment, space lighting and related central utilities. The calculations also include carbon penalties due to raw materials and consumables (transportation and disposal).

A sensitivity analysis was conducted to better understand the overall impacts of changes to process and operations on CO2(e) emissions per product. The largest contributor to the emissions was from HVAC, so most of the changes were restricted to those areas; air change rate reductions, conversion to recirculation, CHW plant updgrades and CHP.

Genzyme Belgium, Campus CO2 & EMS

Built and calibrated (2) two models (580,000 SF) and combined with (3) three small models provided by others (mixed-use labs, 40,000 SF)

Provided in-person training workshops to staff in Geel, Belgium

Correlation of model to campus utility bills; 1.8% electric usage and 6.5% on gas usage

Submitted calibrated campus model to Genzyme for continuous commissioning and EMS integration

While at a prior firm, Dana led the following project from early brainstorming sessions through to final presentations to key stakeholders.

Dana was responsible for developing the energy model (with eQuest) of the main manufacturing building on campus. The model was calibrated to actual hourly metered data for steam, hot water, gas and electricity.

This modeling effort supported Genzyme’s global carbon emissions reductions goals on a year-over-year basis. These efforts were incorporated into the overall Environmental Management System (EMS) and ISO 14001.

Dana streamlined modeling techniques and programmed “preset” parametric simulations into the model for ease of use. He spent a week on site in Belgium auditing the campus and meeting with engineers. Dana gave a demonstration to the Belgian Energy staff prior to closing out the week, in collaboration with Genzyme’s Global Energy Manager. The team used the model to analyze air change rate reductions within the corridors of the main plant. The campus model showed a 0.66% annual cost savings overall for this one measure. The annual campus energy usage is $2.6 million USD for reference.

Upon returning to the States, Dana built a second model of the new manufacturing building. This was calibrated and combined with (3) three other models to yield a fully calibrated campus wide energy model.

Dana continued to provide guidance for ongoing and future use of the campus model.

3D Rendering of Post-Filling Suite in Revit

While at a prior firm, Dana led the following project (confidential client) from early brainstorming sessions through to final presentations to key stakeholders.

Dana conducted an Air Change Rate (ACH) reduction study to evaluate existing HVAC systems for capability. In addition to this, he provided a CFD (Computational Fluid Dynamics) modeling (AutoDesk’s SimCFD) analysis to review the primary space; a 2,200 sq. ft. post-filling suite spanning two floors. Airflow boundary conditions within the CFD model were based on HEPA testing and balancing reports obtained from the client.

Simulations were run for four air change rate scenarios; existing at 39 ACH, 30 ACH, 25 ACH and 22 ACH. All simulations were reviewed and compared in detail, including; clearance time for air throughout the space, areas of low velocity and potential problem air sample locations.

Overall, Dana provided the client with a greater understanding of existing airflow conditions within space; low flow spots, re-circulation, reverse flow, etc.

Results included the following:

    1. Several areas of re-circulation were discovered in corners and near entry ways, which led to reorganization of equipment
    2. A small number of measurement points saw disproportional reductions in velocity compared to room airflow reductions
    3. It was recommended to remove obstructions from specific air inlets / outlets
    4. Minor updates to HEPAs / low-wall returns were recommended if reducing beyond 25 ACH

Embodied Carbon LCA

While at a prior firm, Dana led the following project (confidential client) from early brainstorming sessions through to final presentations to key stakeholders.

A Life Cycle Analysis (LCA) was performed on a 140,000 SF new construction, manufacturing facility. This project was pursuing LEED Certification and the potential points from this effort were deemed critical.

In order to meet the LEED requirements, the proposed design must demonstrate a 10% reduction in global warming potential and a 10% reduction of two (2) of the five (5) other impact indicators when compared to a baseline building. This must be achieved without increasing any indicator by more than 5%.  The analysis considers a service life of sixty (60) years for both the proposed and baseline buildings.  LEED has not set any directions to define the baseline building.

The proposed design did show a decreased environmental impact in all categories, but that decrease was less than 10%. Multiple scenarios were reviewed as alternate construction materials; locally made concrete, adding wood to the structure and window frames, etc.
