Resumen:
A Dutch architect has developed a building system that is a solar energy, low exergy and zero emission building concept, with an integrated seasonal storage system, without energy losses, supplying indoor heating and hot tap water. The building concept is suitable for free-standing, connected, or high-rise residential and utility buildings in all climate zones. The Dutch architect is looking for commercial and research partners to develop the building system.

Summary:
A Dutch architect has developed a building system that is a solar energy, low exergy and zero emission building concept, with an integrated seasonal storage system, without energy losses, supplying indoor heating and hot tap water. The building concept is suitable for free-standing, connected, or high-rise residential and utility buildings in all climate zones. The Dutch architect is looking for commercial and research partners to develop the building system.
Description:
A Dutch architect has developed a building system to lower the use of energy in buildings. The building system is characterized as a seasonal heat storage with the smallest exergy loss (low-exergy), and without any energy loss. In this case exergy (applicability or quality of energy) stands for the temperatures which are used in the building system, and which are as close as possible to the demand temperatures (20 °C indoor and 45 °C shower). The heat storage water temperature is above these two demand temperatures and below 100 °C, and 50 to 90 °C over the year. These temperatures are produced with a vacuum tube semi-transparent solar heat collector which is integrated in the southern facade of the building. The seasonal heat storage volume is integrated with the building volume to achieve that all heat storage losses (more than 50% through 50 cm glass or stone wool insulation) flow into the building and are used as indoor heating.
The Dutch architect is looking for commercial and research partners to implement the building system.
Commercial agreement with technical assistant: Project owners and project developers, initiating and developing zero emission buildings

Research cooperation agreement: European research projects, initiated by larger companies, local authorities, R-Y-D institutes and universities


Advantages and Innovations:
The building system is characterized as a seasonal heat storage without any energy loss. An adjustable ventilation cavity around the storage serves as a heat loss control, and as a leakage protection. A 50 m3 storage tank (9.00 m height, 2.65 m diameter, 86 m2 wall surface) with an annual 50 to 90 °C temperature curve and 8.4 GJ heat load, gives, at an annual average storage temperature of 70 °C with a temperature difference of 50 °C with the 20 °C indoor space, and a U-value of 0.080 W/m2K, an average heat loss of 4.00 W/m2, that gives an annual heat loss of 3,013 kWh or 10.8 GJ for 86 m2 wall surface during 8760 hours. In an optimal embodiment, this heat loss benefits to the building.

Partner sought

Type and Role of Partner Sought:
The building system implementation process is a learn to deliver process with local partners. Construction of buildings, compared to industrial products, face +30% transport costs as part of the construction costs, which characterizes the local organized construction process, instead of fabricating at great distance. Consequently construction processes a few hundred kilometers away, will be organized by different teams, having there own learning process, despite the fact that the outcome is more or less the same.
