  • University of Washington


    The University of Washington Molecular Engineering Building was designed to operate in Pacific Northwest climate without air conditioning.  This 77,000 Square-foot structure uses our M51 bioPCmat above the ceiling in areas where it could be naturally chilled by opening thermostatically controlled vents.  These vents allow nighttime air from the outside atmosphere to pass over the bioPCmat which transitions the phase change material and releases the heat that is absorbed during the day.  The phase change materials play a crucial part in this building and it is an excellent example of intelligent design to create true energy efficiency.

    In an article published about this construction by Korky Koroluk he discusses the role of phase change materials in the future of construction.

    "There has been a push to make buildings lighter, making them quicker and cheaper to build.  The trade-off, though, is indoor temperatures that fluctuate more, which means higher heating and cooling costs. PCMs seem to offer one way to deal with that trade-off."







  • Austrian Pharmacy



    The innovative Hubertus pharmacy wanted to add additional assurance that they could maintain their inventory temperatures at a maximum of 25C, the maxium sustained temperature limit for some of their inventory.  The bioPCmat provided an excellent solution enabling the pharmacy to maintain temperatures below 25C without the use of any additional electricity for heating or cooling.

    "We are delighted to have found another customer and partner Dr. Hubertus Schantl and the pharmacy. The Hubertus pharmacy is certainly a flagship building with character and feel as innovative materials, such as our thermal wall, of course, at home " , said Daniel Pressl PhD, CEO of ABC House GmbH

    The barrier-free features of the building as well as an advanced storage system are characteristic of the way the Hubertus pharmacy wants to go in the future: the way of service and quality at the highest level, in the name of health and on behalf of customers.








  • Broadmoor’s Five Star Restaurant








    BioPCmat™ Improves Temp Control in Broadmoor’s Five Star Restaurant


    The 5 star head chef at the Tavern Kitchen in the Broadmoor Hotel asked for a simple way to quickly and cost-effectively reduce peak heat loads in the kitchen.  Said Rick Prudhomme, Broadmoor HVAC Supervisor, “The kitchen cooks line was running temperatures as high as 120 degrees before the material was installed. After the installation we saw a drop in temperature of 8 -10 degrees. With the material in place the kitchen hot calls were reduced dramatically and the cooling equipment didn’t have to work as hard.  This product was easy to install in the 2x4 drop ceiling. We are very pleased with this product and are looking for more applications throughout the property. “    

    To achieve these improvements the engineering team designed in 350 sf of M51 weight bioPCmat, enough to generate over 17,500 BTUs/transition. To synchronize the material’s melt cycle with the most severe periods of overheating in the kitchen, Phase Change Energy Solutions’ Q 27(80F) material was chosen.  By using a material with a relatively high melt temperature, the engineers could ensure that the material would stay in its “frozen” state until kitchen temperatures rose well above room temperature.

    Adding the material above the ceiling tiles was a simple retrofit.  And its position was well suited to its main objective.  There, the bioPCmat can have the fastest impact as it is in close proximity with the hot air that has collected near the ceiling tiles. 

    How much and how fast the energy is transferred depends on the difference between the bioPCmat’s Q value and the ceiling temperature.  With each degree temperature rise above the bioPCmat’s Q rating,  heat from the room is absorbed more quickly until the “melt cycle” of the material is completed.   When activity slows and the kitchen temperatures drift back down to more normal ambient temperatures, the material naturally freezes again, readying itself for the next rush of patrons. 


  • Palais Sterneck Office Building


    Austrian Office Building Uses bioPCmat to Eliminate Need for Day Time Air Conditioning


    For the four story Palais Sterneck office building in Klagenfurt, Austria, the owners wanted to eliminate the need for air conditioning during the day and also increase the quality of the room climate throughout the summer months.  To achieve this goal they selected to install 1200 square meters of phase change in the roof and ceiling area of the building. 

    In Austria the incentive to minimize energy use is strong, especially for the owner of an office building with many leased tenants.  The Green Building movement has a broad base of support and electricity prices are high relative to the United States.

  • Punahou School


    Punahou School in Hawaii Uses bioPCmat™ To Temper Solar Heat 
    Keep Dancers Cool


    The Punahou School, is a private, co-educational, college preparatory school located in Honolulu City, Hawaii.  The school is renowned for offering a strong dance program that requires a professional dance studio.  The Punahou School  Dance Pavilion is an expansive state-of-the-art facility boasting three studios totaling 4,800 square feet that feature premium, floating dance floors, lofted ceilings and sustainable ventilation.

    Even with the breeze passing through the well-ventilated space, the students can generate significant heat that makes it difficult to keep a comfortable environment.  To help solve this issue the sustainable ventilation strategy was supported by over  2,200 square feet of bioPCmat that was added to the ceiling of the dance area.  The bioPCmat material provided the extra heat absorption needed to make the sustainable ventilation strategy work effectively



  • Modular Classroom


    BioPCmat Eliminates Need For AirCon In Modular Classroom During Early Fall and Late Spring


    Portland State University and Blazer Industries collaborated to develop a modular classroom that  eliminated the need for air conditioning.  The combination of the  BioPCM and a simple ERV system served to keep the building cool.  Relative to many modular classrooms that have small, vhigh-velocity,  air conditioning, or no air conditioning at all, our bioPCM served to increase student and teacher comfort, and improve student academic performance.  The M27, Q 23 bioPCmat material was only used in the walls of modular classroom.  

    On March 23rd at the International Structures for Inclusion (SFI) conference at the University of Minnesota, the SAGE project was recognized as a  2013 Social/Economic/Environmental Design (SEED) Award honorees. The jury found this project compelling as a very replicable model that can be applied to a wide variety of locations to address the need for healthy and productive educational environments. 



Frequently Asked Questions

  • What are Phase Change Materials?

    Many materials such as, chocolate, metals, sand and water/ice change from one physical state to another when reaching there melting point temperature. The melting point of a phase change material is known as its Q-Value.  For water/ice has a Q-Value of 32f°/0c°.  

    When a phase change material reaches its Q-value and changes from the physical state of crystalline solid to that of a liquid (or vise versa) a great deal of energy is adsorbed or released while the material remains at a relatively constant temperature.

    This thermal energy storage phenomenon is known as the latent heat of fusion. Compared to sensible heat storage materials that store energy as a function of an increase in temperature when a material reaches its latent heat of fusion it stores orders of magnitude more energy per unit of volume.    

  • What is bioPCM?

    Our bioPCM™ product is a Phase Change Material designed for use in buildings.  BioPCM is a non-toxic nutritionally inert chemical known as a "fatty ester" that is derived from rapidly renewable plants and nano engineered for optimal thermal energy storage performance in building applications.  BioPCM comes in a variety of thermal energy storage capacities "M-Value" and melting temperatures "Q-value". 

  • Why build with bioPCM?

    Buildings with bioPCM passively maintain comfortable conditions, greatly reducing energy consumption and peak cooling loads.  Simply put, if you desire a better building, you may want to consider bioPCM. 

  • How does bioPCM enhance occupant comfort?

    When air temperatures become too hot bioPCM melts to cool the building, and when air temperatures get too cold bioPCM freezes to warm the building. BioPCMat installed in walls and ceilings reduce radiant temperature fluctuation. The comfort temperature, known as "operative temperature" can be calculated by the average of mean air temperatures and mean radiant temperatures. The calumniation of effects on these factors produces more comfortable buildings when bioPCM is used. 


  • How does bioPCM reduce loads?

    Buildings peak cooling load is typically designed to meet the greater of peak dry-bulb and wet bulb temperatures for all but a range of 1, 2 and 4% of the total hours of the year.  When bioPCM is integrated into the HVAC system design; system capacity can generally be reduced by substantial percentages of design loads without bioPCM.  BioPCM provides the mechanical engineer innovative options for reducing loads at their source reducing air handling unit, duct and plant capacity and assorted costs. 


  • How does bioPCM reduce reduce energy costs?

    BioPCM stabilizes temperatures and thereby reduces the demand for energy by reducing peaks and smoothing the deadband between cooling requirements and heating requirements. This results in both a shift of time of peak and lower peak.  This shift increases the efficiency of HVAC equipment and at times reduces the cost of delivered energy for the utility, resulting in lower costs for the consumer.  

  • How bioPCM does reduce operational costs and increase building value?

    Maintenance of balding infrastructure is typically combined with energy costs and paid for in operational budgets.  The lower these costs are the more valuable a building is generally appraised at, dependent on externalizes and project specifics these benefits can at times out-value the costs of low energy design elements such as bioPCM from day one.  

 A major game changer like bioPCM has to be supported by all involved on the building industry as one of the greatest users of the World’s energy. By reducing the need for usage and helping eliminate the energy peaks bioPCM application is paramount on environmental preservation and EMSS SA is helping its implementation in Europe.
