“…One of the applications is cooling offices by thermal activation of floors during night hours (Fellin and Sommer, 2003), (Lehmann et al, 2007), (Pavlov and Olesen, 2011), (Rijksen et al, 2010) and (Saelens et al, 2011). Another application is lowering peak heating power for residential buildings (Airaksinen and Vuolle, 2013). More close to our application is a study on measured performance of heating and cooling systems using TABS in apartments (Alvi and Qureshi).…”

For the Dutch smart grid demonstration project Meppelenergie, the effects of controlled thermal energy storage within the floor heating structure of a living room by a heat pump are investigated. Storage possibilities are constrained by room operative and floor temperatures. Simulations indicate limitations for floor heating storage due to absorption of solar energy within the house. To balance power for district renewable energy supply, substantial energy can be stored into the floor without violating comfort limits. Heat loss to the outside due to floor heating storage is small in case of low energy houses and can be financially compensated. This may result in a proposition for residents which is equivalent to heating without thermal storage for power balancing purposes.

“…In this sense, and to cover the expected projections of the EV technology, massive integration is, and will definitely be, impacting the behaviour of EV owners and their consumption, which is reflected in the energy bill for them and on the power network for the electricity supplier [10]. Indeed, many studies have been carried out where the management of peak power consumption is a crucial issue for the electricity network [11,12], and the implementation of new strategies adapted to these new challenges are addressed [13]. The main problem lies in the fact that the demand can approach the maximum capacity of the electrical network, even for a short period, causing the energy supplier to pay for energy at a much higher cost to meet the demand and avoid power outages.…”

EV Overnight Charging Strategy in Residential Sector: Case of Winter Season in Quebec

2021

Electric Vehicle (EV) technologies offer a leading-edge solution for clean transportation and have evolved substantially in recent years. The growing market and policies of governments predict EV massive penetration shortly; however, their large deployment faces some resistances such as the high prices compared to Internal Combustion Engine (ICE) cars, the required infrastructure, the liability for novelty and standardisation. During winter periods of cold countries, since the use of heating systems increases, the peak power may produce stress to the grid. This fact, combined with EVs high penetration, during charging periods inside of high consumption hours might overload the network, becoming a threat to its stability. This article presents a framework to evaluate load shifting strategies to reschedule the EV charging to lower grid load periods. The undesirable “rebound” effect of load shifting strategies is confirmed, leading us to our EV local overnight charging strategy (EV-ONCS). Our strategy combines the forecast of residential demand using probabilistic distribution from historical consumption, prediction of the EV expected availability to charge and the charging strategy itself. EV-ONCS avoids demand rebound of classic methods and allows a peak-to-average ratio reduction demonstrating the relief for the grid with very low implementation cost.

“…Studies are showing that properly sealed and insulated building envelopes, with effective heating and ventilation systems, can save up to 50% heating energy, and ensure comfortable indoor environmental conditions [7,8]. Effectiveness of the thermal insulation of a building envelope depends on the properly selected technological solutions, qualified work, and a proper understanding of the value of air tightness [9,10].…”

Impact of Air Tightness on the Evaluation of Building Energy Performance in Lithuania

Abstract:In order to fulfil the European Energy Performance of Buildings Directive (EPBD) requirements for the reduction of energy consumption, European national requirements have been created for building envelope thermal properties and calculation methodology to determine if building energy efficiency is created. This is however not true in all methodologies. The necessity of building air tightness appears only for new A class buildings, and there are no requirements for air tightness for other building classes. Therefore, the aim of this work is to improve the methodology for the calculation of energy efficiency of buildings, while taking into account the air tightness of the buildings. In order to achieve this aim, the sum energy consumption of investigated buildings was calculated, energy efficiency classes were determined, air tightness of the buildings was measured, and reasons for insufficient air tightness were analyzed. Investigation results show that the average value of air tightness of A energy efficiency class buildings is 0.6 h −1 . The results of other investigated buildings, corresponding to B and C energy efficiency classes, show insufficient air tightness (the average n 50 value is 6 h −1 ); herewith, energy consumption for heating is higher than calculated, according to the energy efficiency methodology. This paper provides an energy performance evaluation scheme, under which performed evaluation of energy performance of buildings ensures high quality construction work, building durability, and the reliability of heat-loss calculations.
