Nowadays, radiant ceiling systems can be considered among the technologies capable of meeting sustainable heating and cooling requirements. In order to adequately address design and simulation issues concerning these systems, correct evaluation of the heat transfer process is needed.The aim of this research is to present further evidence on the coo...

In the current context of a world energy situation which demands high-quality indoor environments compatible with rational energy use, the purpose of this work is to present a successful case study of a comfortable, low-energy office building in Madrid, Spain. An exhaustive IAQ and thermal comfort field measurement survey was carried out during the...

A review on climate parameters affecting applicability of passive and low energy heating and cooling techniques is presented. The study has been developed from existing research work results, and aims to serve as a first-stage assessment tool of the viability of these solutions at a particular location, depending on outdoor conditions to be faced....

Two equally-sized cross-flow heat-exchanger prototypes have been designed with a total heat exchange area of 6 m(2) and 3 m(2) respectively, constructed with polycarbonate hollow panels of different cross section. They are connected into a heat-recovery cycle within the whole experimental setup constructed for the tests, which mainly consists of: a...

Evaporative coolers may represent a promising alternative to conventional cooling technologies based on vapor compression systems. Indeed, they present lower production and operative costs, as well as lower environmental impact.

Decarbonization of the building sector is one of the key challenges to achieve the ambitious goal of carbon neutrality by 2050, established in the European Green Deal. In this sense, current trends focus on the promotion of onsite renewable energy sources, as well as on the electrification of heating and cooling demands and sector coupling approach...

An experimental study has been carried out to characterise a laboratory-scale cooling tower (CT) intended to provide water to a high temperature radiant cooling system during night-time. The present study evaluates the possibility of broadening its operation during daytime to precool the outdoor airflow required for ventilation during occupation pe...

In recent years, new technologies, such as Artificial Intelligence, are emerging to improve decision making based on learning. Their use applied to the Architectural, Engineering and Construction (AEC) sector, together with the increased use of Building Information Modeling (BIM) methodology in all phases of a building’s life cycle, is opening up a...

Peak shaving, demand response, fast fault detection, emissions and costs reduction are some of the main objectives to meet in advanced district heating and cooling (DHC) systems.

The building sector presents considerable potential to have its energy consumption reduced. An alternative of current great interest is taking profit of the thermal inertia of the same structure of the building, through embedded pipes, for storing thermal energy generated when costs are lower and/or efficiency is higher, named “Thermal Activated Bu...

Among solar thermal technologies for indoor heating, solar air heaters (SAH) are appealing for implementation on existing buildings due to their simplicity, fewer risks related to the working fluid, and possible independence from the building structure. However, existing research work mainly focuses on winter use and still fails in providing effect...

Conduction heat transfer through building construction elements is one of the main components of space heating and cooling loads, and, thus, one of the key aspects when planning sustainable energy designs in the building sector.
