Flexigrow is a project which analyzes the performance of an all-electric neighborhood of energy efficient houses here in the Netherlands. The goal of this project is to determine whether or not the houses are performing as well as expected and how we might improve their performance using different infrastructure …

Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning …

The increase in renewable energy sources will require an increase in the operational flexibility of the grid, due to the intermittent nature of these sources. This can be achieved for the gas and the electricity grid, which are integrated by means of power-to-gas and vice versa, by applying gas and other …

PowerMatching City. A unique smart grid project.In this presentation, the smart grid project 'PowerMatching City' is introduced. PowerMatching City is a living lab demonstration of the future energy system. In PowerMatching City the connected households are equipped with a mix of decentralized energy …

In this study we tested 39 Lactococcus lactis strains isolated from diverse habitats for their robustness under heat and oxidative stress, demonstrating high diversity in survival (up to 4 log units). Strains with an L. lactis subsp. lactis phenotype generally displayed more-robust phenotypes than strains …

Research has been done to improve the understanding the self-heat effect, due to power dissipation, of temperature-dependant resistors in the VSL water calorimeter. A custom measurement program has been written to be able to control and read out three Agilent 3458A digital multimeters (DMMs). With these …

This report describes the work that has been done on the water calorimeter project at VSL. The calorimeter determines the absorbed-dose-to water Dw in gray, by measuring the radiation induced temperature change. The temperature of the water will change due to irradiation of a beam ionizing radiation. …

Kipp & Zonen, based in Delft manufactures and develops atmospheric measurement instruments, including a scintillometer. Kipp & Zonen currently manufactures the large aperture scintillometer (LAS) MkII and previously manufactured the extra large aperture scintillometer (XLAS) MkI. A scintillometer can …

Which parameters are the most important factors in the decision making process of heat networks?

In this research, the experiences and behaviors of end-users in a smart grid project are explored. In PowerMatching City, the leading Dutch smart grid project, 40 households were equipped with various decentralized energy sources (PV and microCHP), hybrid heat pumps, smart appliances, smart meters and …
