Further, recent comments from MP Mary Creagh, chair of the audit committee, said that government failed to acknowledge a number of its core conclusions in response to a report released earlier this year into the potential public health impacts of an increased number of heat waves in the UK up to 2050. She said: “The Government has…
Following the recent IEA report on the potential effects of the growing demand for cooling (see previous News post) Birmingham University have published a report entitled “A Cool World – Defining the Energy Conundrum of Cooling for All” (see https://www.birmingham.ac.uk/news/latest/2018/07/Global-quadrupling-cooling-appliances-14-billion-increase-energy-consumption.aspx). This report raises the prospect that the cooling sector will, on current trajectory, increase its overall…
In a recent report, https://www.iea.org/cooling/, the IEA state that “Growing demand for air conditioners is one of the most critical blind spots in today’s energy debate”. Global energy demand from air conditioners is expected to triple by 2050, requiring new electricity capacity the equivalent to the combined electricity capacity of the United States, the EU and…

The project is based at Canyon View High School in Waddell, Arizona. Both rooms will monitor HVAC energy, overall building energy…
The UK Government’s Environmental Audit Committee will consider risks to health, wellbeing and productivity associated with heatwaves, review the level of UK resilience to them and assess the Government’s actions to date. The Committee will also be examining public health risks associated with higher temperatures as well as heatwaves (see http://www.parliament.uk/business/committees/committees-a-z/commons-select/environmental-audit-committee/news-parliament-2017/heatwaves-launch-17-19/). Globally, 15 of the 16 highest…

Details of the project can be found at http://www.architectour.net/opere/opera.php?id_opera=6869&nome_opera=Marxer%20Haus&architetto=Falkeis%C2%B2architects&language=1 and http://www.puretemp.com/pcmatters/inspired-by-nature-marxer-haus-takes-wing-in-liechtenstein. As well as many other sustainable features, the apartment block utilises movable “wings”. These climate wings contain 1.4 tonnes of Rubitherm PCMs enclosed in aluminium tubes. …
The US Department of Energy has issued a report in December 2017 (https://www.energy.gov/sites/prod/files/2017/12/f46/bto-DOE-Comm-HVAC-Report-12-21-17.pdf) entitled ENERGY SAVINGS POTENTIAL AND RD&D OPPORTUNITIES FOR COMMERCIAL BUILDING HVAC SYSTEMS. Amongst the high priority technology options listed are phase change materials. The report describes the potential as follows: B.10 Phase Change Materials Technology Description Phase change materials (PCMs) provide passive cooling…
This is a report by Applied Research Associates, Inc. (ARA), under contract to the US Department of Defense Environmental Security Technology Certification Program (ESTCP) (see http://www.dtic.mil/get-tr-doc/pdf?AD=AD1022577). A hybrid Environmental Control Unit (HECU) technology was demonstrated in which the integrated heat exchangers, filled with Phase Change Material (PCM), were fitted into a facility’s air conditioning system at the…
There is considerable evidence to support the fact that overheating of buildings in the UK is becoming an increasing problem. In a recent survey (October 2015), on behalf of WSP:Parsons Brinckerhoff, 83% of the 1,005 London households surveyed stated that they had experienced at least one period of overheating during that summer. Part of the problem…
In order to extend electric vehicle battery life, by protecting batteries from extremes of temperatures, Constellium plans to use wax-based PCMs in aluminium body sections (see http://www.autonews.com/article/20170731/OEM10/170739985/ev-bodies-part-of-the-power-source). The body structure consists of extruded aluminum members that have a hollow cavity, which is filled with a phase change material that acts as a passive cooling system for a battery.…
