Dubai to Build Temperature-Controlled Indoor 'City'
DUBAI, United Arab Emirates—Dubai is planning to build a temperature-controlled city featuring the world's largest mall and an indoor park, as well as hotels, health resorts and theaters. According to Dubai Holding, the developer owned by Dubai's ruler, Sheikh Mohammed bin Rashid al-Maktoum, the all-pedestrian complex would occupy a total area of 48 million ft2 (4.45 million m2). The project "will comprise the largest indoor theme park in the world" under a glass dome that would be opened during winter. The 7 km (4.35 mile) long promenades connecting the facilities would also be covered and air-conditioned during summer, it added. "Tourism is [a] key driver of our economy and we aim to make the UAE an attractive destination all year long," said the Sheikh. "This is why we will start working on providing pleasant temperature-controlled environments during the summer months."

Walmart Refrigeration Head Calls for Reduced Charge, Leakage in Retail
LONDON—Retailers should focus on increasingly packaged equipment, closer collaboration with the supply chain and integrated controls systems, says Richard Royal, Associate Member ASHRAE, Walmart’s senior design manager for refrigeration. Reduced refrigerant charge and leakage, simpler systems and simplified processes should be at the fore in the future of the refrigeration industry. Speaking at the International Institute of Refrigeration’s conference on sustainability and the cold chain, Royal told delegates that it is his desire to improve the efficiency of the business through simplification—"but simple like a smart phone, not like a hammer." One of the key ways of reducing carbon emissions, Royal said, is to reduce direct emissions by significantly reducing refrigerant charge. "We can really impact direct emissions positively," he said. "We believe charge reduction will be one of the single biggest issues for us, together with leak reduction." Royal outlined a three-pronged direct emissions reduction strategy for retailers: reducing charge size; reducing leakage; and transitioning to lower GWP refrigerants.

Qatar Tests Cooling Technologies as World Cup Fever Rises
DOHA, Qatar—Qatar has launched cooling zones for football fans wishing to watch 2014 FIFA World Cup matches currently taking place in Brazil. The move is part of the country’s research to develop efficient cooling technologies to counter the heat of the summer in its stadiums when it hosts the 2022 FIFA World Cup. Summer temperatures in Qatar average around 40°C (104°F), and have recently been as high as 50°C (122°F). The 2010 decision to award Qatar the right to host the competition was largely based on its plans to stage the June-July event using air-conditioned stadiums to combat the heat. Qatar has developed a small, solar-powered prototype stadium that seats 500, but wants to develop more efficient technologies before 2022. Qatar's Aspire Zone Foundation is testing the open-air cooling technology in two locations, both the size of a standard football pitch. A variety of methods are used to cool the areas, including dedicated ventilation units for cooled air, high-level jet nozzles to restrict prevailing winds and air-controlled modifiable dampers.

Emerson Launches Residential HVAC Monitoring Service
ST. LOUIS—Emerson Climate Technologies has launched ComfortGuard Monitoring Service, a monitoring service that enables homeowners to manage their heating and cooling equipment by providing real-time information designed to predict problems and prevent energy waste. The system's 10 sensors collect and transmit data via a Wi-Fi connection whenever the heating and cooling system runs. With every run, a "32-point" inspection is conducted, including a scan for efficiency changes, filter degradation and component problems. Any indication of a problem generates a notice to a monitoring team at the company who analyzes the data before sending a system alert to the homeowner and a service professional. Homeowners are also provided emailed alerts, efficiency and filter status reports, and a comprehensive monthly report.

Honda 'Smart Home' Showcases Energy-Efficiency Technologies
DAVIS, California—Honda has opened a highly efficient "living laboratory" home that showcases technologies that enable net zero energy living and transportation. The home, located on the West Village campus of the University of California, Davis, is capable of producing more energy on-site from renewable sources than it consumes annually, including enough energy to power an included Honda Fit EV for daily use. The Honda-developed home energy management system and an energy efficient design will allow the home's occupant to use less than half of the energy of a similarly sized new home in the Davis area for heating, cooling and lighting. The home is also three times more water-efficient than a typical U.S. home. The project is designed to achieve more than 11 tons of CO2 reduction per year compared to a conventional home and vehicle. A member of the college's faculty will live in the home. The project is intended to enable the company, along with researchers from UC Davis and Pacific Gas and Electric, to evaluate new technologies and business opportunities to intersect housing, transportation, energy and the environment.

Solar PV Shining As 'Hot' Source of Energy
PARIS—In 2013, for the first year ever, more solar PV capacity was installed worldwide than wind capacity, according to the recently released 2014 edition of the "Renewables Global Status Report" by Renewable Energy Policy Network for the 21 Century (REN21). The annual report from the network of renewable energy stakeholders—including governments and industry—found that more than 39 MW of installed solar PV capacity was added last year, bringing the total up to 139 GW worldwide. China, the United States, Brazil, Canada, and Germany remain the top countries for total installed renewable power capacity.

ASHRAE Seeks Papers for 2015 Annual Conference
ASHRAE is seeking papers for its 2015 Annual Conference. "The 2015 Annual Conference in Atlanta will have a strong focus on the design, construction and operation of high performance buildings as four of the nine tracks in the conference focus on advanced design guidance, modeling, operation and optimization, and indoor air quality, which are key aspects of high performance buildings, along with one track that explicitly considers measured results and other aspects of high performance buildings," said David Claridge, conference chair. Conference paper abstracts are due Sept. 22, 2014. Upon acceptance, papers will be due Jan. 5, 2015. These papers undergo a single-blind review. Full technical papers also are due Sept. 22, 2014. Papers submitted for review must be both technically accurate and clearly written. These papers undergo a rigorous double-blind review and will be published in ASHRAE Transactions. The 2015 ASHRAE Annual Conference will be held June 27–July 1 in Atlanta.

ASHRAE BEQ Program Qualifies as Energy Rating Option for Florida
Under amended legislation recently signed into law, ASHRAE's Building Energy Quotient (bEQ) building energy rating and labeling program now qualifies as an energy rating option for buildings in Florida. Florida Governor Rick Scott signed House Bill 7147, which qualifies the bEQ program as an approved system. The provisions in the bill amend a 2013 Florida law specifying requirements for energy ratings for all residential, commercial and state-owned buildings. In recent months, ASHRAE worked on an amendment to better define what constitutes an approved building energy efficiency rating system. Under the change, the bEQ program qualifies as an approved system. The bill became effective July 1.
