Data from: Eyeless Mexican cavefish save energy by eliminating the circadian rhythm in metabolism
The eyed surface form and eyeless cave form of the Mexican tetra Astyanax mexicanus experience stark differences in the daily periodicities of light, food and predation, factors which are likely to have a profound influence on metabolism. We measured the metabolic rate of Pachón cave and surface fish at a fixed swimming speed under light/dark and constant dark photoperiods. In constant darkness surface forms exhibited a circadian rhythm in metabolism with an increase in oxygen demand during the subjective daytime, whereas cave forms did not. The lack of circadian rhythm in metabolism leads to a 27% energy savings for Pachón cave fish compared to surface fish when comparing both forms in their natural photoperiods. When surface forms were tested under constant dark conditions they expended 38% more energy than cave forms under equivalent conditions. Elimination of the circadian rhythm in metabolism may be a general feature of animals that live in perpetually dark food-limited environments such as caves or the deep sea.

Dataset: Cool birds: First evidence of energy-saving nocturnal torpor in free-living common swifts Apus apus resting in their nests
<p><a name="_Hlk94722524"></a><span>Daily torpor is a means of saving energy by controlled lowering of the metabolic rate (MR) during resting, usually coupled with a decrease in body temperature. We studied nocturnal daily torpor <span>under natural conditions</span> in free-living <span>common swifts <em>Apus apus</em> resting in their nests as a family using two non-invasive approaches. First, we monitored nest temperature (T<sub>nest</sub>) in up to 50 occupied nests per breeding season in 2010-2015. Drops in T<sub>nest</sub> were the first indication of torpor. Among </span></span><a name="_Hlk97457770"></a><span><span>16,673 </span></span><span><span>observations, we detected 423 events of substantial drops in T<sub>nest</sub> of on average 8.6°C. Second, we measured MR of the families inside nest boxes prepared for calorimetric measurements during cold periods in the breeding seasons of 2017 and 2018. We measured oxygen consumption and carbon dioxide production using a mobile indirect respirometer and calculated the percentage reduction in MR. During six torpor events observed, MR was gradually reduced by on average 56% from the reference value followed by a decrease in T<sub>nest</sub> of on average 7.6 °C. In contrast, MR only decreased by about 33% on nights without torpor. Our field data gave an indication of daily torpor, which is used as a strategy for energy saving in free-living common swifts.</span></span></p>

<p>Dataset supporting publication: “A novel ROM methodology to support the estimation of the energy savings under the Measurement and Verification protocol” (publication available for download: <a href="https://zenodo.org/record/4062276#.X33rSO3tbIU">GEOFIT Zenodo</a>)</p> <p>Datasets resultant from simulation of the integrated system into buildings.</p> <p>Conference paper presented in <a href="https://www.bso2020.org/">IBPSA-England Building Simulation and Optimisation Conference 2020</a></p> <p>This paper presents a novel Reduced Order grey box Model (ROM) methodology, based on a Resistor-Capacitor (RC) network, which supports the creation of the baseline energy consumption and the estimation of energy savings due to Energy Conservation Measures (ECMs) under the Measurement and Verification protocol. Within this scope, a description of the RC network, including a calculation of the parameters’ needed to execute the ROM, are presented. This ROM methodology is demonstrated on an educational building located in Sant Cugat, Spain as part of the H2020 GEOFIT project. The results presented in this paper demonstrate that the ROM is sufficiently accurate for the creation of the baseline energy consumption and for estimating the energy savings of different ECMs.</p>

Dataset related to the article HOW HEART FAILURE PATIENTS PERFORM DAILY LIFE ACTIVITIES: AN INNATE ENERGY-SAVING STRATEGY
<p>This record contains raw data related to the article HOW HEART FAILURE PATIENTS PERFORM DAILY LIFE ACTIVITIES: AN INNATE ENERGY-SAVING STRATEGY</p> <p> </p> <p><strong>Background </strong></p> <p>Cardiopulmonary exercise test (CPET) and six-minute walking test (6MWT) are frequently used tools to evaluate physical performance in heart failure (HF), but they do neither represent activities of daily living (ADLs) nor fully reproduce patients’ symptoms. We assessed differences in task oxygen uptake (taskVO<sub>2</sub>), both as absolute value and as percentage of peakVO<sub>2</sub> (%peakVO<sub>2</sub>), ventilation efficiency (VE/VCO<sub>2</sub> ratio), and dyspnea intensity (Borg scale) in HF and healthy subjects during standard ADLs and other common physical actions.</p> <p><strong>Methods </strong></p> <p>Healthy and HF subjects (ejection fraction (EF) <45%, stable conditions) underwent CPET. All of them, carrying a wearable metabolic cart, performed a 6MWT, two 4-minute treadmill exercises (at 2 and 3 km/h), and ADLs: ADL1 (getting dressed), ADL2 (folding 8 towels), ADL3 (putting away 6 bottles), ADL4 (making a bed), ADL5 (sweeping the floor for 4 minutes), ADL6 (climbing 1 flight of stairs carrying a load).</p> <p><strong>Results </strong></p> <p>Sixty HF patients (age 65.2±12.1yrs; EF 30.4±6.7%, peakVO<sub>2</sub> 14.2±4.0ml/min/kg) and 40 healthy volunteers (58.9±8.2yrs, peakVO<sub>2</sub> 28.1±7.4ml/min/kg) were enrolled. For each exercise, patients showed higher VE/VCO<sub>2 </sub>ratio, %peakVO<sub>2</sub>, and Borg scale value than controls, while absolute values of taskVO<sub>2</sub> and exercise duration were lower and higher, respectively, in all activities, except for treadmill (fixed execution time and intensity). Differently from Borg Scale data, metabolic values and exercise time length changed in parallel with HF severity, except for ADL duration in very short (ADL3) and composite (ADL1) activities. Borg scale values correlated with %peakVO<sub>2</sub>.</p> <p><strong>Conclusions. </strong></p> <p>During ADLs, patients self-regulated activities in parallel with HF severity by decreasing intensity (VO<sub>2</sub>) and prolonging the effort.</p>
