In this paper, we give an overview of an on-going research work aiming at assessing the benefits that could be drawn from applying advanced software engineering techniques – namely model-driven architecture, component-based approaches and model-based system engineering – to support building life cycle tasks (especially design ones) which entail making use of digital models. 

This article shows the combination of a thermal-airflow simulation program with an energy systems analysis model in order to assess the use of natural ventilation as a method for saving energy within residential buildings in large-scale scenarios. The aim is to show the benefits for utilizing natural airflow instead of active systems such as mechanical ventilation or air-conditioning in buildings where the indoor temperature is over the upper limit of the comfort range.

Indoor air quality and thermal comfort of the passive school buildings should be particularly paid more attentions due to those new passive school buildings adopted highly airtight building envelopes. In this study indoor environment of a very densely occupied classroom with displacement ventilation has been investigated. In order to appropriately model the classroom, all the simulation parameters are based on a typical real classroom structure, its air tightness and infiltration rate were measured.

This paper deals with typical residential buildings constructed according to the national energy-efficiency standard in China’s severe cold region. Dynamic heating/cooling loads of residential building models were simulated via a factorial experiment. The electricity consumption of residential buildings was investigated, and the characteristics of the power load were analyzed statistically. The results show the cooling/heating/power load indexes of S–N- and E–W-oriented multi-story residential buildings in China’s severe cold region.

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.

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.

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.
