Building energy and CFD simulation to verify thermal comfort in under floor air distribution (UFAD) design

Corporate tenants require ever-greater design certainty with respect to all aspects of proposed developments. Because of this, its relative novelty and a design methodology that differs from ceiling-based Variable Air Volume (VAV) air conditioning, Under Floor Air Distribution (UFAD) has faced significant scrutiny. Building simulation offers methods to understand the implications of design decisions.

Application of an anticipative energy management system to an office platform

This paper depicts a formulation of the global home electricity management problem, which consists in ad-justing the electric energy consumption to the cost and availability variations of the power supply. A proposed global multi-layer solving approach includes first the computation of consumption/production coordination plans and then the dynamic matching to the actual con-sumption/production data. This paper focuses on the anticipative problem.

Determining heat use in residential buildings using high resolution gas and domestic hot water monitoring

Residential buildings consume about a third of the UKs total energy and the need to reduce this as part of achieving the 2050 CO2 emissions targets driving the interest the modelling and performance simulation of homes. While simulation and modelling tools are in wide spread use, the detailed empirical data with which to understand the effect of systems and opera-tional complexities of households on the consumption of energy is less developed than it is for commercial buildings.

New method for quick evaluation of the heating energy demand of residential buildings

In this article, the main research goal is to present a model for rapid assessment of specific heating energy consumption of residential buildings. In the first part of this research paper the main inputs that could influence the building heating demand are identified.The next step in the development of the prediction model was to conduct dynamic simulations with different combinations of the inputs and to obtain a database of results.  With this database, a multiple regression was applied and a simple (3 inputs) and accurate (R2=0.987) model was obtained.  

Building simulation of energy consumption and ambient temperature: application to the PREDIS platform

This paper presents the first step modelling process of a smart building  in order to ensure better energy management and human comfort in buildings. It consists on combining physical models and experimental measurements in order to have more adapted models for virtual simulation and optimal control. Advantages and difficulties related to this process will be detailed through a defined use case of a smart building: PREDIS.   The paper starts, by introducing the studied building and its different components: HVAC system and thermal envelope.

Comparison of human thermal models, measured results and questionnaires

Increasing concern about building sector energy consumption and the simultaneous need for an acceptable thermal environment makes it necessary to estimate in advance what effect different thermal factors will have on occupants. So far most human thermal comfort models are based on estimates assuming steady-state conditions. However, this often leads to underestimations of local cold or hot surfaces. These kinds of models does not take into account variable conditions.
