To study the impact variations in input on output vari-ation (Sobol index) of building model, a stochastic model (time series) of variables is introduced. To build the time series we used data measured in a building for each hour for a duration of one month.
The external temperature does not appear directly in the model but affects all the input. So after model it as Auto-Regressive process we propose to model input, for example the heating flux, by an ARMAX process.

For the purpose of revitalizing traditional architecture, we considered the characteristics of a traditional architecture cluster with regard to cross ventilation, and from an environmental engineering point of view, we proposed techniques to improve the surrounding environment. In this report we make use of and improve the urban area model used in a prior report, as well as use CFD to take into account the effects of surrounding topography. To improve the urban area model, we make detailed computations of the wind pressure coefficient distribution.

Spaces with high heat generation such as telecommunication base stations (TBS) increase sharply recently. Huge energy is consumed for air-conditioning because of large indoor heat rejection and year round cooling in these spaces. Thermosyphon heat exchanger is an appropriate cooling technique for TBS, which can make full use of natural outdoor cooling resources without much electrisity consumption.

The Birmingham Zero Carbon House is a retrofitted Victorian house that has achieved carbon negative performance.! Future predictions of temperatures are showing an increase in Cooling Degree Days (CCD), even under a low carbon emissions scenario.! This paper aims to investigate the human behaviour effect on maintaining indoor thermal comfort in future weather, in various models of cooling in the Zero Carbon House.

The decrease of heat demand in low energy build-ings, very sensitive to solar and internal gains, and the development of new HVAC systems call for a reexam-ination of the usual modeling approaches in building simulation. A focus is brought on an air-to-water heat pump plugged to a radiant heating floor (RHF) by a hydraulic loop installed in a typical low energy dwelling. Using a RADTEST evaluated Modelica slab model, several floor thermal masses under four differ-ent control strategies are compared to determine their impact on HVAC system performances.

This paper describes the use of optical recognition technologies to augment the physical design space and its aesthetic drivers with a myriad of design performance variables available through advanced environmental analysis simulations to create an integrated and collaborative high-performance design platform. By utilizing various hardware and software systems, this design platform can capture critical physical information to be translated into a 3D digital environment where the digital model can be interpreted and various analysis information can be extracted.

This paper evaluates the influence of windows in thermal energy performance of a social interest bulding in Dunas District - Pelotas/RS,  analizing the performance for heating and cooling over the year. The original design was modeled and analized through the energy efficiency software “Design Builder” (v:2.3.5.036), considering different sizes of window openings - 12.5%, 20% and 45% of the floor area - and three types of sun protection - blinds, shutters and brises-soleil. The changes made in the sizes of the windows and in the type of sunscreens didn’t affect significantly the thermal-ene
