Envelope insulation is a relevant technical solution to cut energy consumption and reduce environmental impacts in buildings. Insulation Cork Boards (ICB) are a natural thermal insulation material whose production promotes the recycling of agricultural waste. The aim of this paper is to determine and evaluate the environmental impacts of the production, use, and end-of-life processing of ICB. A...

In this paper, a novel algorithm for estimating clothing insulation is proposed to assess thermal comfort, based on the non-contact and real-time measurements of the face and clothing temperatures by an infrared camera. The proposed method can accurately measure the clothing insulation of various garments under different clothing fit and sitting postures. The proposed estimation method is inves...

To practically apply vacuum insulation panels (VIPs) to buildings or home appliances, VIPs have demanded long-term lifespan with outstanding insulation performance. Service lives of VIPs enveloped with Al-foil and three-layer Al-metallized envelope are calculated. For Al-foil envelope, the service life is longer but edge conduction is too large compared with the Al-metallized envelope. To incre...

1. Abstract Topology optimization is employed to define the geometry of the cross-section of any masonry block that minimizes its thermal transmittance, with the aim of maximizing the thermal insulation of masonry buildings. Constraints on the mechanical properties of the block are also prescribed. The effect of the design constraints on the optimal layout of the blocks is investigated. The the...

OBJECTIVE To examine whether providing thermal clothing improved the health of patients with heart failure during winter. DESIGN Parallel group randomised controlled trial. SETTING Large public hospital in Brisbane during winter 2016. PARTICIPANTS 91 patients with systolic or diastolic heart failure who were over 50 years old. INTERVENTION 47 patients were randomised to receive thermal ...

The main insulation system in high-voltage direct current (HVDC) transformer consists of oil-paper insulation. The formation of space charge in insulation paper is crucial for the dielectric strength. Unfortunately, space charge behavior changes because of the corrosive sulfur substance in oil. This paper presents the space charge behavior in insulation paper induced by copper sulfide generated...
