Article
Full-text available
As the cooling requirement and the energy prices are increasing rapidly across the world, the need to develop highly efficient cooling equipment is rising as well. Adiabatic cooling employs evaporation to pre-cool the air flowing through a closed-loop coil. This study examines various adiabatic evaporative cooling pads in terms of their pre-cooling...
Article
Full-text available
The growing terrorism threats across the world play an important role in the design of civil buildings and living areas. The safety of personnel is a top priority in unclassified buildings, especially military buildings. However indoor air quality and thermal comfort has a direct impact on personal productivity and ability to concentrate on duties...
Article
Full-text available
The use of air conditioning technology is accompanied by an increase in electricity consumption, which is linked to an intensification of fossil fuel extraction. This in turn calls for developing cooling solutions of higher energy efficiency. The aim of this study is to examine energy consumption reduction of direct evaporative cooling technology f...
Article
Full-text available
Single family houses consume substantially more thermal energy per floor area compared to multi-apartment buildings to satisfy space heating or cooling demand. Over the past decades there has been an undisputed evidence of a temperature rise across the world that has led to a growing concern of more extreme weather patterns and regular seasonal hea...
Article
Full-text available
Military facilities feature distinctive requirements with regards to building technical and structural design, material use and indoor environmental conditions (IEC), as these buildings serve specific purpose and the personnel occupying the premises may wear uniform or protective clothing (administrative staff, special forces, training personnel et...
Article
Full-text available
In recent years construction of bullet resistant walls has become very common not only for military buildings but also for public and residential buildings. The existing wall structure in those buildings is reinforced by ballistic panels. However, in the cold climate regions external application or installation of the ballistic panels can cause int...
Article
Full-text available
In most cases there are no specific and clear design requirements defined in local building codes, the responsibility for appropriate design of military buildings therefore lies primarily on third party design service contractors that are hired upon a short term agreement, whereas government is primarily involved in financing stages and military pe...
Article
Full-text available
Natural gas heating systems are traditionally very popular in private sector in Latvia because of their numerous advantages, such as high efficiency, relatively low CO 2 emissions, automation possibilities and convenient fuel supply, as well as widely available natural gas distribution network. Household natural gas consumption has remained fairly...
Article
Full-text available
Healthy building design guides are cogent and necessary. While elements that contribute to healthy buildings are multifactorial, the perception of sound versus noise is subjective and difficult to operationalize. To inform the commissioning process, the acoustics in an open office was examined following the first international building certificatio...

The overall goal of this three-phase project at the University of Washington Tower (UW Tower) was to address and advocate the importance of providing satisfactory IEQ, sustainable renovated workspaces, and shared IAQ strategies that could be implemented during indoor construction and renovation projects.
Article
Full-text available
Building stock is one of the crucial energy consumers in Europe. The majority of the European residential and public buildings were constructed after the Second World War. The external building envelope of these buildings has very poor thermal insulation properties with regards to modern requirements. There are several well known building retrofitt...
Article
Full-text available
Supply airflow rate and supply air temperature can be varied to maintain the room temperature setpoint according to the air temperature conditions outdoors and heating loads indoors. Increasing the supply air temperature and decreasing supply airflow rate can reduce energy consumption. However, it causes insufficient air circulation, leading to ris...
Article
Full-text available
In this paper authors point out that overheating in buildings during summer season is a major problem in moderate and cold climates, not only in warm climate zones. Mostly caused by solar heat gains, especially in buildings with large glazed areas overheating is a common problem in recently constructed low-energy buildings. At the same time, comfor...
Article
Full-text available
The stability of indoor air parameters is a very important factor, essential for such institutions as museums, schools and hospitals. Nowadays the use of renewable energy for space heating became one of the top priorities in modern building design. The active and passive solar energy as well as heat pumps are widely used nowadays. However, such tec...
Article
Full-text available
To develop potential of the cities in the field of energy efficiency improvements and use of renewables, there is a need for new and more ambitious goals in line with the actual situation. Growing concern of smart city development and urban resilience has become increasingly embedded in urban planning, national security and energy policy. One of th...
