Desiging Buildings for Operational Energy Savings of 35% to 50% Over Standard Systems
The image above depicts the energy loss of buildings with viewed in infrared. Building designed with Integrated Thermal Storage Ventilation can expect operational energy savings of 35% – 50% over standard building systems. In addition, they have performed better in side by side tests of buildings with several more advanced, but capital intensive, ECMs. These types of results are common and have been verified by independent audits of Termobuild’s building performance. The core of the operational performance gains come from:
- Active thermal storage of free cooling (outside air) and heating (e.g. body heat/IT equipment /lighting) throughout the day and night. Active thermal storage is not to be confused “thermal mass” in passive mode.
- The non-hydronic radiant effect of the thermally charged concrete floors
- Reduction of cooling and heating calls to the energy intensive HVAC equipment
For example, cool night-time air can be circulated through the concrete floor slabs, thermally “charging” them for the next day. The cooled building serves as a heat sink during the daytime hours, reducing the need for mechanical cooling.
The off-peak cooling strategy leverages discounted energy pricing from the utility, while reducing daytime HVAC demand calls. During daytime occupied hours, the thermally charged floors maintain indoor comfort with minimal mechanical cooling
Termobuild’s software algorithm manages the system to keep it running optimally 24/7. The software is installed within the building control system utilizing ASHRAE Standards to guide its decisions. The software is proprietary, yet simple enough to require no maintenance.
Building Systems Maintenance
Overall lifecycle costs are reduced significantly with a Termobuild system design. First, many of the operational components of the HVAC system can be reduced in size or eliminated – reducing the cost to operate and maintain (parts, etc.). Second, more complex, digital ECMs can be left out of the design if desired, reducing the need for extensive facilities management training, experience, and head count.
Termobuild does not limit which additional ECM systems can be implemented within a building. It will work in an integrated fashion with most any ECMs that have been specified, while increasing even further the performance results of the building
