Technical Committee: 07.06 Building Energy Performance
Sponsor: REHVA
A consistent strategy for energy saving and sustainability should benefit from the all the opportunities opened by scientific and technological development. One of the biggest challenges in a building is to find the right equilibrium between the energy demand and the well-being provided to occupants. The evolution of information and communication technologies, together with the decrease of the cost of sensors and monitoring systems, opened new perspectives. Nowadays the decision-making process is much better informed and based on performance indicators, which are widely used in energy and environmental rating systems for buildings. The experiences of European leaders will be presented
1 Data Driven IEQ Control in Low Energy Buildings
 |
Karel Kabele, Dr.Ing., Czech Technical University in Prague |
Energy performance of buildings has an impact on the quality of the indoor environment. Nevertheless, the technical building systems can ensure the desired state of the internal environment, occurs in many low-energy buildings the deterioration of subjective perception and dissatisfaction of users. The paper focuses on issues related to the design of concept and controll of heating and ventilation systems in low energy residential and school buildings, and its impact on the quality of the indoor environment.
2 Affordable IEQ Monitoring Solutions for Small and Medium-Size Buildings
 |
Manuel Carlos Gameiro da Silva, Dr.Ing., REHVA |
It is presented a case study of a building where an IEQ monitoring system has been installed. The architecture of the monitoring system is based on sensing systems from different manufacturers, but having in common a USB digital output. The data communication, as well as the developed softare codes to ensure the data processing, collection and display are also presented.
3 Occupant Behavior Monitoring and Engagement: Low Investment Measures to Optimize IEQ and Save Energy in Buildings
 |
Stefano Corgnati, Ph.D., P.E., REHVA |
The most important types of interactions of occupants with the building façades or control systems are defined. The models available to integrate human behavior on simulations are explained. Results of the different studies, both field works and simulations, are presented and discussed. The corrective measures to improve the indoor environmental quality are explained, as well as the strategies to promote more environmental friendly behaviors.
4 Environmental Performance of a Building Translated into Financial Performance
 |
Frank Hovorka, REHVA |
Besides the positive impacts on environment and the reduction of exploitation coss of buildings, the environmental certification of buildings may contribute to rise their value. The methods to translate the environmental performance into finantial benefits are discussed in this presentation.
