Data is fundamental to understand how much a building consumes, how much it is efficient and whether thermal comfort is adequate. However, how should this data be evaluated? Is it still possible to increase energy efficiency of buildings? A solution would be to make a comparison with similar contexts: for example, how much does a building consume on average under specific climatic conditions? How much energy can it obtain from its installed renewable energy sources?

The Aktiv-Stadthaus in Frankfurt am Main is the first large apartment building in a city to be built according to the Efficiency House Plus standard. The first residents moved in during the summer of 2015. The aim of its innovative energy concept is to generate more renewable energy over the space of a year than is used by the building itself.

A growing body of research attaches figures to the value of benefits that energy efficiency measures deliver to public agencies, private entities, economies as a whole, and to individual citizens. Renovating private homes has a benefit-cost ratio of 4:1, reflecting reductions in healthcare expenditure, elimination of energy subsidy pay-outs, job creation and greater economic empowerment of citizens who are lifted out of energy poverty.

In the center of the "Poblenou" neighborhood of Barcelona, the "Koh" restaurant has been renovated, following the EnerPhit / Passivhaus protocol. "Koh" means "island" in Thai, and thus reflects the idea of the owner, of creating a quality site in different aspects: quality of the food, quality of the interior design and quality of the interior environment.

An understanding of human thermal comfort has proven to be one of the key components of energy efficiency in buildings. Human comfort is more to comfort than just temperature and humidity. For instance, the radiative energy that is emitted from walls, the air speed and also physiological factors such a as the people’s metabolic rate, the skin wettedness, and skin emissivity all have an effect.

The EU Commission has been developing Level(s) - a framework of macro-objectives and indicators aiming to help building professionals to report on the environmental performance of buildings. As well as energy and material impacts, Level(s) provides a framework for reporting the quality of the indoor environment achieved with these resources, including air quality, thermal comfort, climate change resilience and life cycle cost/value.

[31 May 2020 - COVID-19 update for Registrants]. On behalf of ASHRAE and AIVC, we wish to inform you that a decision was made to postpone the IAQ 2020 Conference. It will be rescheduled in 2021 as a face-to-face conference in Athens, Greece. At this time, the 31 May deadline for submitting papers is suspended.
The decision to postpone the conference was made in large part by the results of the survey completed by some 170 authors

This new residential complex in Tirol, completed in 2018, is a passive house construction with 20 condominiums, 19 underground parking spaces and 8 carport spaces. The structure is U-shaped and is divided, due to the slope, in a basement with underground parking, a ground floor and 4 other above-ground floors.
The outstandingly low levels of energy demand and consequential CO2 emissions have made it achieve the Bronze status of the Austrian klimaaktiv criteria.
