Behavioral patterns and profiles of electricity consumption in dutch dwellings

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)...

Study on route division for ship energy efficiency optimization based on big environment data

In the case of the global energy crisis and the higher sound of energy saving and emission reduction, how to take effective management measures of ship energy efficiency to achieve the goal of energy saving and emission reduction, put forward a new challenge for the development of shipping technology. The application of big data technology...

A CMOS Temperature Sensor with a 49fJ·K2 Resolution FoM

This paper presents the most energy-efficient CMOS temperature sensor ever reported, with a resolution FoM of 49fJ·K2, 2.7× better than the state-of-the-art. It consists of a Wheatstone bridge made from poly-silicon resistors, which is readout by a 2nd-order Continuous-Time Delta-Sigma modulator (CTDSM). This approach leads to a high resolution ...

Are we moving fast enough? The energy renovation rate of the Dutch non-profit housing using the national energy labelling database

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 CO₂ emissions. Energy renovations in dwellings offer unique...

An assessment of energy-saving solutions for the envelope design of high-rise buildings in temperate climates: A case study in the Netherlands

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...

Dynamic building stock modelling: Application to 11 European countries to support the energy efficiency and retrofit ambitions of the EU

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...

Multistage Complex-Impedance Matching Network Analysis and Optimization

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...

An integrated control-oriented modelling for HVAC performance benchmarking

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...

A 30 ppm < 80 nJ Ring-Down-Based Readout Circuit for Resonant Sensors

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...

Insight in actual energy use in houses as a basis for energy performance contracting

Energy performance contracting is based on the idea that the investments for the improvements of the energy performance of a building through better insulation and more efficient installations will be covered by the savings of the use of energy in the use phase. The external contractor takes care of all the investments costs and guarantees the...

Energy-Greenbelt: Transformation of empty office buildings to housing with the use of greenhouses in the air-field

This report studies about the transformation of empty office area to housing area by integrating greenhouse into the air field of the dwelling. There are some cases integrating greenhouse into the house due to the contribution of energy saving aspect. Making low-energy consumption area is indispensable consideration in the project. One plot in...

A CMOS temperature sensor with a voltage-calibrated inaccuracy of ±0.15°C (3σ) from -55 to 125°C

This paper describes an energy-efficient CMOS temperature sensor intended for use in RFID tags. The sensor achieves an inaccuracy of ±0.15°C (3σ) over the military temperature range (-55 to 125°C) and dissipates only 27nJ/conversion: over 20× less than a previous sensor with comparable accuracy and resolution [2]. This energy efficiency is...

Energy efficient walking with central pattern generators: From passive dynamic walking to biologically inspired control

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...
