The current discussion about energy saving measures in the built environment and the forthcoming new European guidelines “Energy efficiency in Buildings” motivated an aluminium facade company (Hydro Buildings Systems) to set up an interdisciplinary team f
In order to reduce the energy cost for heating and improvethe internal conditions during the summer period in greenhouses, they have been investigated different solutions including passive cooling techniques and hybridsystems. Such kind of solutions is the minimization of the ventilation losses through cracks and openings, the increase of the thermal mass of the greenhouses and the use of ground heat exchangers.
This paper describes an educational and experimental tool developed under LabVIEW environment at LASH/DGCB (France) laboratory of ENTPE. The objective of this tool is to make students sensitive with HVAC equipments, measurements, heat recovery, and regulation techniques in order to expand and test heating, cooling and ventilation control strategies. A large room of the Buildings Sciences Laboratory (LASH) is equipped with balanced mechanical ventilation and a global control/data acquisition system.
Double Skin Facades (DSF) have been a recently developed technology to improve the thermal performance of conventional façades of buildings which use large glazed areas. However, there has been a lack of test information on the behaviour and performance o
This paper outlines the findings of a research project undertaken as part of the design for St. Anthony’s School, a primary school in the town of Gudalur situated in tropical southern India. The objective of this paper is to demonstrate a design approach
The sensation of comfort in buildings depends on externaland internal variables: the well-known PMV method relates the expected temperature with the physiological behavior of the human body. Some models have discussedthe relevance of adaptation factors, in order to explainthe higher expected good temperature of users living in warm climates. The same PMV method has been modified for these climatic situations.
Highly glazed buildings are often considered to be airy, light and transparent with more access to daylight. Their performance, however, regarding to energy use and thermal comfort issues is often questioned. Passive solar systems such as Double Skin Faades are likely to improve the overall building performance if integratedproperly. This article deals with energy and indoor climate simulations of double skin office buildings in Sweden using a dynamic energy simulation tool.
Adoption of daylight as an energy efficiency strategy is especially relevant for a climate like Malaysia, as the country experiences long sunshine hours throughoutthe year. An important aspect of effective daylight strategy is the performance of the window in permitting daylight entry. This paper presents a study conducted to account daylight availability in an office interior undervarious fenestration options; namely window-wall-ratio (WWR), glass types and application of external shading devices of varying depth.
This document presents the theoretical study of evaporativecooling designed for the outdoor spaces in the Spanish pavilion of the coming International Exhibition in Zaragoza 2008.
It is a well notorious fact that if you get below the surfaceof the earth a few meters, the temperature tends to be constant and at 8 to 12 degrees, depending on latitude.So, it does not take an architect to appreciate that if you could move outside air through a buried pipe, you could alter its temperature and then move it into a house where it can warm or cool the homes interior.Underground temperatures can be very beneficial in balancingthe thermal comfort of the house.
