In order to solve the dynamic characteristics of fuel cell thermal energy in building equipment intelligent control system, this paper proposes application research system renewable modelling. A cold water proton exchange membrane cogeneration scheme was proposed. The heat produced by installation is carried out cooling and exchanged between exchanger hot always heated exchanger. At same time, ...

Construction equipment management and performance data are valuable assets for large contractors that need such historical data for decision making about resource allocation and equipment replacement; however, with large amounts of accumulated data, traditional data analysis based on a transactional system becomes increasingly inefficient. This paper summarizes a web-enabled data warehouse we d...

Background 270 million workplace accidents occur annually. In Uganda, Kampala district has the highest workplace injury and fatality rates. However, information on personal protective equipment (PPE)-hand gloves, hardhats, overalls, safety boots, earplugs, safety harness with lanyard, and face shields-utilization among building construction workers remains scarce. We assessed PPE utilization an...

In-building Distributed Antenna System (IB-DAS) has proven to be one of the most promising In-Building Solutions (IBS) to provide coverage and capacity for indoor users. We consider optimal deployment of the passive IB-DAS, focusing on mathematical optimization models based on integer programming, for the topology design and optimal equipment selection of IB-DAS. The models minimize the cable c...

The boundary between the communication equipment at the network edge and the servers within the data center is blurring. Appliance vendors are flooding the market with new capabilities, while router vendors are scrambling to add these services to their traditional transport services. The result of this competition is a set of ad-hoc technologies and capabilities that provide services at the net...

A new device with the ability to measure heat loss from building facades is proposed. Yet to be commercially developed, the U-value Meter can be used as stand-alone apparatus, or in combination with thermographic-equipment. The U-value meter complements thermographs, which only reproduce surface temperature and not the heat loss distribution. There is need for a device that measures the heat lo...
