UNEP looks to the sea for a cool change in Egypt


The Intercontinental Electricity Company states that cooling technological innovation results in a lot more than 7 for every cent of the world’s greenhouse fuel emissions.

In Egypt through summer months, close to half of the country’s electricity goes in the direction of air conditioning. Temperatures can hit 40°C and remain in the large thirties in the course of the year, primarily in towns suffering from the urban heat island outcome.

The United Nations Ecosystem Programme (UNEP) not long ago finished a feasibility study to try and adopt a much more weather-welcoming solution to cooling in Egypt. Conducted in New Alamein Town on the north coast, it investigated the enhancement of a seawater air conditioning process.

The procedure operates by pumping seawater into a cooling station and passing it as a result of a heat exchanger, in which it absorbs heat from properties. Interesting air created from the chilly drinking water is utilized to preserve snug temperatures in the structures, when the warm water is despatched back into the sea.

It is predicted the cooling plant will take two decades to establish, costing somewhere around AUD$170 million and a additional AUD$30–36 million for the distribution network.

The 30,000 tonnes of refrigeration (TR) ability would lower refrigerants emissions by roughly 99 for every cent and carbon dioxide emissions by 40 for each cent.

This will support Egypt meet up with its targets in phasing down hydrofluorocarbon (HFC) emissions beneath the Montreal Protocol and the Kigali Amendment.

According to the Head of the Egyptian District Cooling Code and UNEP guide Alaa Olama, Egypt is an excellent place to trial cooling systems simply because it is at present setting up 22 “smart cities”. A ton of the new technologies target on implementing cooling systems that do not use energy.

The analyze was initiated by means of the Multilateral Fund of the Montreal Protocol, and the UNEP District Vitality in Metropolitan areas Initiative will consider the research to the amount of execution.

Sea h2o has been utilized to neat buildings ahead of. In Australia, Danish architect Jørn Utzon and engineer Ove Arup implemented an ground breaking seawater cooling technique when the Sydney Opera Home was built. The engineering has recently been getting traction in the east.

“It’s an essential resolution for new metropolitan areas,” said Olama.

Open access to ASHRAE-UNEP eLearning modules


Access is now available to 3 HVAC&R eLearning modules and various other cost-free means via the ASHRAE-UNEP Portal.

The Refrigerants Literacy module delivers a simple knowledge about refrigerants forms, guidelines, classifications and management techniques. It is aimed at non professionals in the field, these as facility managers, policy makers, and other persons who are involved in refrigerant problems from a non-specialized standpoint. It can also serve as an introduction to refrigerant fundamental principles for individuals new to the industry.

The Audio Management of Refrigerants module assessments most effective tactics for vital environmental challenges, ASHRAE expectations, and refrigerant terminology for air conditioning and refrigeration specialists. Subject areas coated consist of rules of refrigerant restoration, recycling, and reclaiming, as effectively as lubricants, their houses and purposes, like compatibility concerns with various refrigerants. The class embraces risk-free handling, service, and installation of refrigeration products utilising modern day refrigerants. It also supplies introduction to refrigerant administration applications, certification strategies and relevant guidelines and laws.

These two modules can be accessed utilizing the code “Ozonaction&ashrae1”.

At last, the Electrical power Performance Literacy for Air-Conditioning and Refrigeration Devices module is built to educate creating region coverage makers, organization leaders, and community stakeholders about the positive aspects of air conditioning and refrigeration, the scientific concepts concerned, and aspects that lead to maximum vitality efficiency.

This module can be accessed applying the code “Ashrae&unepeel1”.

The ASHRAE-UNEP portal also features a college training course. Obtain to this system is by means of an on line registration form.

As very well as the discovering components, the portal includes the reduce GWP awards, the recent ASHRAE and UN Surroundings OzonAction Workplan, information and functions, and other methods.

Strategies to stop our cities overheating


Launched at COP26, Beating the Heat is a handbook that provides techniques for sustainable cooling of metropolitan areas. Made by the Cool Coalition, UNEP, RMI, World wide Covenant of Mayors for Local weather & Vitality (GCoM), Mission Innovation and Clean up Cooling Collaborative, it delivers planners an encyclopedia of confirmed possibilities to support amazing metropolitan areas.

In latest weeks, a lot focus has targeted on how well the entire world is tracking from the Paris Agreement’s aims of limiting world temperature rises to 1.5°C, with the summary currently being that we are heading past 2.5°C unless of course we consider more robust motion. The problem for towns is even additional urgent. Investigation displays that the world’s metropolitan areas are heating up at two times the world-wide regular rate because of to the urban warmth island outcome. By 2100, towns throughout the entire world could heat as much as 4°C on regular.

The authors take note that hotter cities could be catastrophic for public health. The variety of people uncovered to summertime highs earlier mentioned 35˚C is predicted improve 800 per cent to get to 1.6 billion by mid-century.

The issue will be felt most by lower-money districts within towns, which are typically “hot spots” owing to a deficiency of eco-friendly areas and to the co-location of industrial functions. Citizens of these spots are also less probably to be ready to find the money for cooling. All those who can, will commonly buy much less expensive and a lot less power productive styles that will exacerbate the warmth island outcome.

Beating the Warmth: A Sustainable Cooling Handbook provides the equipment to create full-technique methods to addressing urban cooling across three main actions:

  • Effective setting up and structure at the scale of the city or city district, with an emphasis on heat-minimising urban variety and layout, nature-primarily based remedies, and amazing surfaces built to decrease the city heat island influence, in turn also cutting down cooling loads in buildings.
  • Maximizing the thermal effectiveness of buildings and minimising cooling loads employing passive making style procedures with an emphasis on main by case in point on governing administration buildings and increasing the floor with creating energy codes and benchmarks.
  • Effective and finest-healthy cooling technologies and operations to supply the necessary volume of cooling with the minimum volume of strength, emissions and anthropogenic heat.

The guide includes 80 circumstance reports and illustrations that can be merged for distinctive city contexts. It incorporates two Australian case scientific tests, equally from Western Sydney: the Change Down the Warmth Method and Motion Strategy, and the Weather Tailored People Shelters Structure Competition.
