Matern - Creating Building Systems That Work for You
GREEN Home GREEN Projects GREEN Members Energy SAVINGS Going GREEN? Commissioning

Matern Professional Engineering is well versed in energy saving concepts for building systems.   We have performed lighting retrofits, central energy plant life cycle cost analysis for various HVAC concepts, geothermal designs and solar domestic water heating and photovoltaic systems designs for numerous clients throughout the Southeast.  We provide comparative system studies for the majority of our projects; looking for long term and first cost savings for Owners. 

We frequently work with local power companies to earn our clients rebates for central energy plant upgrades, lighting upgrades and solar installations.  These projects require feasibility studies that must be sent to the power companies and require coordination with them over the course of the project.  Over the past several years, we have helped achieve over $3,000,000 in energy rebates for our clients.  We are well versed in this process and are prepared to assist your energy saving endeavors.   

The following projects are examples of the various studies and energy efficient technologies we have implemented throughout the Southeast.

  • St. Johns County Government – 200,000 Square Feet, 12 Buildings
  • Winter Park Government Buildings – 200,000 Square Feet, 4 Buildings

We also hold the engineering contract with Florida Housing Finance Corporation to provide: Energy Consumption Model – which at a minimum, takes into account specific factors including, but not limited to, unit size, building orientation, design and materials, mechanical systems, appliances, characteristics of the building location.

Umatilla Health Clinic - LEED® Silver

The $3.6 million project began in May 2007 and was completed one year later. The new facility enables the Lake County Health Department to offer clinical services to the surrounding community, including family health, maternity, immunizations and specialty clinics.  The project included a complete overhaul of the existing 4,600-square-foot structure and adding 11,000 square feet of space. Added features to the health facility include exam rooms, nursing workstations, storage rooms and a laboratory. A few of the green-building initiatives implemented at the health clinic included:

• Increased insulation
• Solar panels
• Fluorescent lights with motion sensors that deactivate when rooms are unoccupied
• Low-flow fixtures coupled with sensors and automatic controls
• Native Florida landscaping
• A computerized heating and cooling system with an advanced filtration unit
• A reflective roof to decrease heat-island effects

The Umatilla Health Clinic has solar hot water panels which generate up to 95% of the building’s domestic hot water demand year round without the need for electric heating. The HVAC system will have an Energy Recovery Ventilator (ERV) that will reduce the building’s overall tonnage by 10% during peak months.

Florida Gulf Coast University Biscayne Hall Student Housing - South Village LEED® Silver

MPE was part of the team that helped attain the LEED® silver certification for the five-story 124,075SF dormitory that contains most of the same features as Everglades Hall. MPE provided design services that resulted in achieving 10 of the total 34 earned LEED® credit points. MPE was also instrumental in achieving 4 of the 7 required prerequisites. MPE provided the energy modeling services required for EA Cr 1 and 2 and the fundamental commissioning services required for EA Prerequisite 1. Design considerations that were implemented to help achieve these credits were energy recovery technology, environmentally friendly refrigerants, domestic solar water heating system, low flow plumbing fixtures, lighting and temperature control strategies, and high efficiency air filtration. Particular challenges presented were that the pursuit of LEED® certification began after the building was essentially designed based on a previous building. Selected design strategies were implemented into the project late in the design process to help achieve the LEED® silver rating without requiring total redesign of the building. This building was occupied by students the fall semester of 2009.

Seminole County Public Schools Midway School of The Arts Elementary School LEED® Certified

Matern Professional Engineering, Inc. (MPE) provided full MEP/FP engineering services for this elementary school which included the mechanical design of a Thermal Energy Storage Central Energy Plant (TES) that produces 100% of the day’s cooling requirements during an off-peak energy usage schedule. The system runs the ice tanks from Noon until 9:00 PM, every day, with no supplemental cooling from the air-cooled chillers.  This central energy plant was designed for a future transportation center facility on the same site with expansion capabilities to accommodate the addition of a future middle school and a future high school on a site over a mile away.   MPE provided Florida Power & Light (FP&L) and the Owner with a feasibility study, comparing the cooling load profiles and Life Cycle Costs (including annual electricity, other O&M and capital costs) of a conventional chilled water system verses a TES system. Operation of the TES system’s feasibility study included modeling full storage, partial storage and demand limiting cooling strategies. The TES system’s chiller sizes (tonnage), storage size (ton-hours) and system schematics were studied for optimization. The submittal documents in the report included design loads, original input data files from the load program, schematic diagrams showing fluid flows, pipes, control valves, heat exchangers and an hourly design of day operating sequences. The hourly cooling load profiles for the various cooling options were developed with an industry hourly analysis program provided by the US Department of Energy and Trane Corporation.

Advanced Commissioning Services & Solutions, Inc. (ACSSI) provided a comprehensive commissioning process for the evaluation and performance of the central energy plant and thermal energy storage (TES) system for this elementary school. ACCSI also provided the full fundamental commissioning scope required by the LEED for Schools EA pre-requisite #1 which will confirm MPE’s design of the off-peak cooling system.   The team coordinated with MPE and FP&L to review the final TES system before the commissioning of the TES installation occured. ACCSI also confirmed with MPE that the existing design of an alarm system, within the current Building Control System (BCS), notifies the client of any condition in which subsequent on-peak or non-optimized operation occurs. Other parameters which are being monitored include refrigerant pressure, chilled water temperatures and other critical system operating parameters. ACCSI confirmed MPE’s Energy Model as it pertained to the LEED for Schools EA prerequisite #1 and verified that it met the intent of FP&L’s rebate structure. This fundamental commissioning involved full commissioning of the water side, air side and controls throughout the project.  ACSSI and MPE worked hand in hand to commission the central energy plant and provide the final commissioning report to FP&L for verification of the rebate.

Hernando County Public Schools Weeki Wachee High School
This newest addition school is being designed to meet LEED® Silver certification and includes three academic centers, administration, media, athletic, dining and performing arts buildings surrounding a central landscaped courtyard.

The campus will utilize a chilled water central energy plant (CEP) design. The system will utilize high efficiency air-cooled screw compressor chillers. The HVAC load calculations indicate, for the Weeki Wachi High School and the new K-8 campuses, that three 400-ton screw compressor chillers along with 48 Calmac TES tanks will serve these campuses.

Matern Professional Engineering is providing all mechanical, electrical, fire protection, plumbing and technology systems design services, including HVAC systems design for this new 278,000SF high school with 2,064 student stations.
