Liquid hydrogen (LH2) takes up less storage volume than gas but requires cryogenic vessels. State-of-the-art applications for passenger vehicles consist of double-wall cylindrical tanks that hold a hydrogen storage mass of up to 10 kg. The preferred shell material of the tanks is stainless steel, since it is very resistant against hydrogen brittleness and shows negligible hydrogen permeation. T...

Computer simulations are used to assess the impact of thermal insulation on transfer heat and moisture in exterior walls residential buildings. The effects internal external a room terraced family house compared using COMSOL Multiphysics software package, evaluating influence placement expanded polystyrene distribution wall while monitoring indoor air temperature during heating cooling regimes....

Four reduced-height (5 m) BS 8414-1 façade flammability tests were conducted, three having mineral-filled aluminium composite material (ACM-A2) with polyisocyanurate (PIR) and phenolic (PF) foam stone wool (SW) insulation, the fourth polyethylene-filled ACM (ACM-PE) PIR insulation. Each was constructed from a commercial engineer’s design, built by practising installers. The ACM-PE/PIR burnt so ...

Many of China’s older buildings, built in the 1970s and 1980s, faces several indoor temperature heating energy consumption problems. Based on an investigation analysis old hotel Urumqi, this paper proposes a renovation plan to improve reduce consumption, thereby introduce sustainable development strategy for winter. The effects different plans were simulated using DesignBuilder PVsyst software....

Frequency Domain Spectroscopy (FDS) is an effective tool allowing assessing the condition of oil-paper insulation system in power equipment. However, results from these measurements are known to be greatly influenced by various parameters, including insulation aging, moisture content, and insulation geometry/volume, together with environmental condition such as temperature. In this contribution...

This paper aims to evaluate the energy-saving potential, affordability and thermal comfort performance of various passive building retrofit measures for a historical (late nineteenth-century Victorian house) renovation. Three types interior (i.e. internal wall insulation, glazing upgrade airtightness improvement), classified as traditional advanced measures, are further grouped into 63 combinat...
