An experience on integrating monitoring and simulation tools in the design of energy-saving buildings

In this paper we describe the design and thermal behaviour of a bioclimatic Auditorium at the National University of La Pampa, used for teaching activities in Santa Rosa, La Pampa (Argentina). The building was monitored in winter and simulated with SIMEDIF for Windows, a code developed at the Non Conventional Energy Research Institute (INENCO, Argentina). Then, a new project of a similar building was proposed for General Pico city, and the obtained physical model was used to simulate the building under the summer temperatures of the new city. The building was redesigned and passive solar strategies were applied to reduce heating and cooling loads. The final layout and the monitored thermal behaviour of the new building in winter and summer are described. Without additional costc, the new building savings were 50% in heating requirements respect to the conventional layout, and 70% in the requirements of conventional energy for cooling.     

Verification of the energy-saving effect of the district heating and cooling system—Simulation of an electric-driven heat pump system

A district heating and cooling system (DHC) is expected to be a promising energy-saving measure for high-density business areas in Japan. However, it has not been verified what advantages of the DHC are important for energy conservation. The clarification of this issue is supposed to contribute to improving the energy efficiency of the DHC.
