Verdaasdonk, B.W. (author), Koopman, H.F.J.M. (author), Van der Helm, F.C.T. (author)Like human walking, passive dynamic walking—i.e. walking down a slope with no actuation except gravity—is energy efficient by exploiting the natural dynamics. In the animal world, neural oscillators termed central pattern generators (CPGs) provide the basic rhythm for muscular activity in locomotion. We present a CPG model, which automatically...journal article 2009

Jiang, J. (author), Chang, Z.Y. (author), Pertijs, M.A.P. (author)This paper presents an energy-efficient readout circuit for micro-machined resonant sensors. It operates by briefly exciting the sensor at a frequency close to its resonance frequency, after which resonance frequency and quality factor are determined from a single ring-down transient. The circuit employs an inverter-based trans-impedance...journal article 2015

(author), Stegnar, G. (author), Sijanec Zavrl, M. (author), Brattebø, H. (author)A dynamic building stock model is applied to simulate the development of dwelling stocks in 11 European countries, over half of all European dwellings, between 1900 and 2050. The model uses time series of population and number of persons per dwelling, as well as demolition and renovation probability functions that have been derived for each...journal article 2016

Campos Martins, G. (author), Serdijn, W.A. (author)Some systems like RF energy harvesters have power transfer efficiency as one of the most important specifications. Therefore, the efficiency of the matching network, which affects the entire system’s efficiency, plays an important role. When the impedance transformation factor between the antenna and its load is high, the matching network...journal article 2016

Satyavada, Harish (author), Baldi, S. (author)Energy efficiency in building heating, ventilating and air conditioning (HVAC) equipment requires the development of accurate models for testing HVAC control strategies and corresponding energy consumption. In order to make the HVAC control synthesis computationally affordable, such control-oriented models are typically a simplified version...journal article 2016

Raji, B. (author), Tenpierik, M.J. (author), van den Dobbelsteen, A.A.J.F. (author)The building envelope is the interface between the interior of the building and the outdoor environment. A building's energy consumption to a large extent depends on certain envelope design elements. As a consequence, for achieving high levels of energy-saving in buildings, design measures with high impact should be firstly defined and then...journal article 2016

Bedir, M. (author), Kara, Emre C. (author)In EU member states, the consumption of electricity per dwelling has remained more or less constant, although the consumption of large appliances has decreased considerably in the last 2 decades. This stabilization is caused by the increased ownership, usage and consumption levels of Information, Communication and Entertainment (ICE)...journal article 2017

Filippidou, F. (author), Nieboer, N.E.T. (author), Visscher, H.J. (author)The existing housing stock plays a major role in meeting the energy saving targets set in the Netherlands as well as in the EU. Existing buildings account for 38% of the final energy consumption in the European Union (EU), and they are responsible for 36% of the CO<sub>2</sub> emissions. Energy renovations in dwellings offer unique...journal article 2017

Suárez, Rafael (author), Escandon, R. (author), López-Pérez, Ramón (author), León-Rodríguez, Ángel Luis (author), Klein, T. (author), Silvester, S. (author)According to the IPCC Climate Change projections by 2050 temperatures in southern Spain will have increased noticeably during the summer. Housing-in its current form-will not be able to provide a suitable response to this new climate scenario, and will in turn prompt an increase in cooling energy consumption and a series of problems relating...journal article 2018

Mlecnik, E. (author), Straub, A. (author), Haavik, T. (author)In the EU, housing retrofit rates have to increase to about 2.5–3% of the housing stock per year to achieve policy goals. The development of new business models and collaboration of SMEs in a fragmented market is expected to result in an increase in home renovations. This study presents a way to better understand the usefulness of the...journal article 2019

Filippidou, F. (author), Nieboer, N.E.T. (author), Visscher, H.J. (author)Energy renovations offer unique opportunities to increase the energy efficiency of the built environment and for the existing housing stock; they are the most important solution. Usually, energy savings are based on modeling calculations. However, recent research has shown that the predicted energy consumption differs largely from the actual...journal article 2019

Nguyen, P.A. (author), Bokel, R.M.J. (author), van den Dobbelsteen, A.A.J.F. (author)Purpose: Refurbishing houses is considered a key measure to improve the energy efficiency of the built environment. However, little is known about the implementation and outcome of housing renovation for energy upgrades in the Vietnamese practice. The purpose of this paper is to investigate the energy performance of the current housing stock...journal article 2019

de Vries, G. (author), Rietkerk, M. (author), Kooger, R. (author)In order to reach climate goals, policymakers stimulate homeowners to invest in sustainable measures in and around their house. Unfortunately, however, the number of green home measures lacks behind. This article introduces perceived hassle as an important reason for this shortfall. It is claimed that homeowners perceive hassle during different...journal article 2019

Graamans, L.J.A. (author), Tenpierik, M.J. (author), van den Dobbelsteen, A.A.J.F. (author), Stanghellini, Cecilia (author)The increase in global food demand has led to the introduction of new food production systems. One key example is the plant factory. Plant factories face the same challenge as many high-tech building functions: high energy demands resulting from high internal heat loads. In this study we investigate how this energy demand can be reduced...journal article 2020
