CODYBA is a software addressed to designers, teachers and research organisms. This software determines the energetic fluxes of a building zone. The basic data are the zones geometry and constitution. The main parameters are the climatic conditions, the internal loads and the heating and air conditioning powers, as well as their regulation mode.
In addition to the fact that the serviceability of building constructions used as exhibition halls has to be ensured, the climate stability of the whole structure has to be increased. Exemplary building physical calculations with transient boundary conditions (simulations) were set off by the aim to modernize the “ Herzog-Anton-Ulrich-Museum” in Brunswick.
This paper deals with comparison between the CFD method and the zonal one, and also model experimental validation. The zonal method consists of a dwelling decomposition in several isothermal air zones, in contact with walls.
This paper addresses the utility and the difficulties to predict the actual energy consumption of existing buildings, that can be useful to calculate true energy conservation potential taking into account the real usage of the building. True indoor temperature is of particular importance but also the availability of casual and solar gains. A sensitivity analysis on the set of behavioural parameters shows that the casual gains are highly dependent on the number of occupants at home and the lighting scenario, which requires to collect information about the occupants way of life.
We present an advanced formulation of zonal models for calculating indoor air temperature and flow distributions in buildings. Our modeling is based on modularity:
This paper is focused on a mathematical model applied to both building thermal analysis and control systems design. A lumped approach is used to model the room air temperature and a multi-layer model for the building envelope. The capacitance model allows to study the transient analysis of room air temperature when it is submitted to sinusoidal variation of external air temperature, representing a case study for a cold day in the south Brazil. To evaluate the building performance with thermal parameters, we use MATLAB/SIMULINK.
This article introduces building simulation in conjunction with a HVAC system, especially a split system, considering thermal and moisture behaviors of the perimeter walls. A description of such a HVAC system is taken from TASK 22/ HVAC BESTEST [4]. Its model had already been validated by analytical methods and verified by comparative tests [5]. In order to simulate the thermal and moisture behaviors of the walls a TYPE 158 [6] has been developed based on the finite element method. Its results are in very good agreement with the humidity response function [7].
The continuing development of the Industry Foundation Classes (IFC) standard by the International Alliance for Interoperability (IAI) creates new possibilities for achieving interoperability for design software through the use of a common object model of the building and its open data transfer standard. Several architectural CAD tools are already IFC compliant. However, in-depth knowledge of the highly complex IFC object model is required to develop IFC-compliant software.
Horizontal and vertical brises soleil are dominant elements in the modernist tropical architecture. It was the obvious answer to the question on how to adapt the modernist architecture, developed in moderate climates, to the tropical climate with its particularly high solar radiation. Buildings for example like, the buildings of the Central University of Venezuela in Caracas (Carlos R. Villanueva, 1945 – 1953) or the ministry of education and culture MEC (Lúcio Costa, Le Corbusier et al.
