“…The two most widely adopted thermal comfort models are the Heat Balance model (as found in EN 7730 -2006 [48]) developed by Per Ole Fanger [70] and the Adaptive model (as found in ASHRAE 55-2004 [71] and EN 15251-2007 [72]) and presented in the work of de Dear et al [73], Nicol et al [74] and Humphreys and Nicol [75]. Berglund [76] provides an overview of some of the main mathematical models used for predicting thermal comfort.…”

In response to UK government policy mandating the construction of 'zero carbon' homes by 2016 there have been significant changes in the way dwellings are being designed and built. Recent years have seen a rapid uptake in the adoption of the German Passivhaus standard as a template for ultra-low energy and zero carbon buildings in the UK. Despite genuine motivations to mitigate climate change and fuel poverty there is a lack of research investigating the long-term performance of Passivhaus buildings in a rapidly changing UK climate. This paper sets out to investigate whether Passivhaus dwellings will be able to provide high standards of thermal comfort in the future or whether they are inherently vulnerable to overheating risks. Scenario modelling using probabilistic data derived from the UKCP09 weather generator (WG) in conjunction with dynamic simulation and global sensitivity analysis techniques are used to assess the future performance of a range of typical Passivhaus dwellings relative to an identical Fabric Energy Efficiency Standard (FEES) compliant dwelling over its notional future lifespan. The emphasis of this study is to understand what impact climate change will pose to overheating risks for Passivhaus dwellings relative to the de facto (i.e. FEES) alternative, and which design factors play a dominant role in contributing to this risk. The results show that optimization of a small number of design inputs, including glazing ratios and external shading devices, can play a significant role in mitigating future overheating risks.

“…It is noteworthy that the net floor area or typology are not defined because this is a theoretical example. The main point is that energy needs by end use and by unit of floor area are much lower than the verified in average buildings and are based on the end-use energy terms presented on [20][21][22].…”

The present study investigates the provision of heating, cooling, electricity, and domestic hot water consumption for a 100 m2 off‐grid zero‐energy residential building housing four occupants. Notably, the building is equipped with a hydrogen stove for cooking, and its electricity consumption is sustained throughout the year using renewable energies, independently of the electrical grid, with hydrogen energy storage. Using a Trombe wall for heating, surplus power is converted and stored in a dedicated hydrogen tank. TRNSYS software models analyze the system, demonstrating thermal comfort for 98.3% of the year. With 83 m2 of photovoltaic panels, the house operates off‐grid, slashing CO2 emissions by 8154.7 kg annually by reducing boiler energy consumption through waste heat utilization. The hydrogen tank minimizes the required battery size while the Trombe wall significantly contributes to heating, especially in colder climates. Remarkably, the building's renewable energy usage curtails emissions up to 8.5 times more than a Toyota Prius, showcasing its environmental impact in reducing greenhouse gas emissions.
