Shaping Tomorrow's Built Environment Today
June 6, 2024
The Spanish city of Valencia has an innovative plan to generate clean energy—turning cemeteries into hubs of green energy by installing solar panels on top. The project has been dubbed Requiem in Power, or RIP, and was launched in May with the goal of becoming the largest urban solar farm in Spain. Valencia has identified multiple cemeteries within city limits that can accommodate 6,658 solar panels, with 810 already installed at multiple locations. When complete, the project will generate over 440,000 kilowatts of energy and save 140 tons of carbon emissions every year. Read more

In the ongoing quest for sustainable energy solutions, innovative and sometimes unexpected solutions are necessary to implement renewable resources—one such potential breakthrough revolves around plain, old-fashioned beach sand. Sand batteries represent an emerging approach to energy storage and are particularly effective in harnessing and retaining energy from intermittent sources like solar and wind and at storing heat at high temperatures. Read more
Purdue University researchers revealed that the air coming out of office buildings in urban areas may be more polluted than once believed.  The findings, published in a new study in the journal Cell Reports Sustainability, that modern buildings continually release volatile organic compounds (VOCs) to outdoor air are likely to be an important contributor to the VOC burden of the urban atmosphere. The team conducted direct measurements of outdoor-indoor air pollutant exchange in a high-performance office building using state-of-the-art air quality instrumentation and an advanced building automation platform.

Progression of Energy Efficiency Regulations on Fans
Join Journal Managing Editor Kelly Barraza and guests Christian Taber and Michael Ivanovich as they discuss how the fans and blowers industry has evolved in recent years. Key talking points will include the progression of energy efficiency regulations on fans, ASHRAE Standard 90.1, large diameter ceiling and circulating fans, drives and commercial and industrial applications of the technology.

This article demonstrates how computational fluid dynamics (CDF) analysis can be used to systemically evaluate the impact of UV-C intensities on the effectiveness of an upper room ultraviolet germicidal irradiation system, showing that adding even a small amount of UV-C energy can significantly reduce the probability of infection.

ASHRAE and UNEP's OzonAction have signed a new Memorandum of Understanding (MOU) to renew and expand their long-standing collaboration on environmental protection and sustainable development in the refrigeration and air conditioning sectors. Both parties agree to explore opportunities to advance standards, codes, norms, and guidelines concerning refrigerant management, including aspects related to flammability, operation, and maintenance. The new ASHRAE-UNEP MOU calls for collaboration to support the evolving needs of developing countries by providing specialized products and services that facilitate refrigerant management for climate protection and energy efficiency. Read more

Tesla continues to face delays with its Dojo data center project in Austin, Texas, following problems with construction planning implementation, the firing of the project’s director of infrastructure and finding qualified contractors. Though more contractors are entering the space due to the rising demand, hyperscalers and data center owners may still face challenges in finding a qualified workforce, as well as issues with procuring generators, power supply systems, electrical switchgear and power distribution units, which often pushes back the construction timeline for these projects. Read more
