In the past 40 years, since the first oil crisis in the seventies, energy and climate goals have been shaping many countries´ policy and legislative agendas. The building sector plays a crucial role in achieving these goals, considering the energy use attributed to buildings and its huge potential for improved energy performance. Whereas in the past most of the focus was on reducing the energy consumption, it is not clear that better performing buildings must ensure an acceptable Indoor Environmental Quality (IEQ), by providing higher Indoor Air Quality (IAQ) and comfort levels for their occupants. Building ventilation entails both challenges and opportunities to achieve this goal. In 2019 the AIVC completes its 40th year of existence and the conference organisers thought that it would be good to pay a particular interest to the evolution during these 40 years.

The Colombian Association of Air Conditioning and Refrigeration ACAIRE, invites you to one of the most important events in Latin America to be held in the city of Barranquilla - Colombia. The congress constitutes a platform for exchange of scientific knowledge in the field Climate Control and Cooling, which is of global interest and supports the need to formulate innovative, efficient and sustainable engineering solutions for the society of the future.

Central Europe towards Sustainable Building Prague 2019 (CESB19) event will be a part of 2019 international Sustainable Built Environment conference series convened under auspices of the four international organizations: iiSBE, CIB, UNEP-SBCI, FIDIC and the Global Alliance for Building and Construction.

Building and construction industry specialists, researchers, and policymakers will convene in Hong Kong for the 5-day World Building Congress. Local, regional and internationally renowned industry specialists will deliver keynote talks, case studies and dynamic presentations to reveal the latest smart building, construction and infrastructure trends, practices and developments.

The Conference comes from the observation that the human factor affects significantly the actual energy performance over the building life cycle. The incorporation of behavioral insights into the building design and operation is starting to be recognized as a key topic. Research efforts are therefore needed for fully integrating human dimensions in the building energy performance: data on occupant behaviour have to be collected and properly elaborated; drivers and motivations have to be understood; indexes describing users comfort preferences and the impact on health and productivity have to be identified; new modeling approaches and tools need to be developed; design and operating strategies centered on occupants have to be defined.

BTUS researchers recently presented energy-savings results from 73 commercial building owners and operators who are using Energy Management and Information Systems (EMIS) at their sites. In its second year of operation, the Smart Energy Analytics Campaign has gathered and analyzed data from over 400 million square feet of install space for efficiency insights and savings achieved by owners that are implementing EMIS, along with associated technology costs.

Looking around the typical home or office, many homeowners and employees will find a staggering amount of technology on display: the refrigerator that keeps our food fresh; the thermostat that controls room temperature; the array of electronics to enable (and sometimes impede) our productivity; the lights that make tasks visible at night.

“As this large technology base continues to grow, the number of ways that a building can use energy grows with it, meaning that the best opportunities for saving energy in buildings are always changing,” said Jared Langevin, research scientist at Lawrence Berkeley National Laboratory (Berkeley Lab). “What’s more, the pace of change is relatively quick—ask a homeowner from the year 2000 what they think of smart thermostats or where they buy their LED light bulbs, and they’d have little clue of what you were talking about.”

Into this technology development maelstrom enters Scout, a software program developed by the U.S. Department of Energy Building Technologies Office (BTO) in partnership with Berkeley Lab and the National Renewable Energy Laboratory (NREL). Scout estimates the national impacts of emerging energy-efficient technologies and systems on building energy use and operating costs, drawing from a consistent energy use baseline, standard energy conservation measure (ECM) definitions, and realistic simulations of stock turnover and ECM competition dynamics. With support from BTO, Scout is now available as a web-based application for sharing Scout’s capabilities with the broader energy analysis community.

“The Scout web app ( will be of interest to users who want to know how new energy-saving technologies or approaches fit into the larger U.S. market for energy efficiency—both at present and decades into the future,” said Chioke Harris, an NREL research engineer collaborating with Langevin on the project. Looking for simple definitions of technologies and their national impacts to compare with similar technologies? Visit the ECM Summaries page. Curious about the total impacts of a technology portfolio and which end uses or technologies contribute most to those impacts? The Analysis Results page presents those insights. Just want to know about the status-quo outlook for U.S. building energy use? The Baseline Energy Calculator provides that information.

The web app can help all kinds of folks better understand how energy use in buildings might change with the adoption of energy-efficient technologies, as well as the potential cost savings from those technologies. Companies that own or manage large building portfolios can learn about the financial performance of various technologies using metrics that can help them with the business justification for investing in energy efficiency. Energy policy organizations and nonprofits can look at those same technologies through the lenses of their energy and cost savings potential for a specific region or across the United States. Researchers interested in developing next-generation energy-efficient building technologies can use the baseline energy use projections and ECM definitions to better understand where they can have the greatest impact. Users intrigued by the app can take the leap and download the Scout analysis engine to get results custom tailored to their unique interests.

“Looking ahead, Scout’s flexibility to folding in new input data, technology areas, and valuation metrics will be essential in keeping the program viable as the building energy use landscape continues to change,” said Langevin. In just the last few months, for example, Scout’s baseline data were updated reflect the latest Energy Information Administration national energy use projections and new analysis capabilities were piloted that will allow users to value energy efficiency differently by time of day and season, reflecting an increasing focus on buildings as a source of grid services. All of these updates were pushed to the Scout GitHub repository and were carefully documented with an eye towards transparency.

“We expect that will bring new tests of Scout’s flexibility, opening the program to exciting use cases and avenues of investigation that have yet to be explored,” Langevin said. In the meantime, interested readers are encouraged to get started with their own Scout analyses and to keep an eye out for new Scout releases.
