A BEMS assisted commissioning tool to improve the energy performance of HVAC systems

This paper is a presentation of a concept for a new automated tool that uses the capabilities of Building Energy Management Systems (BEMS). Some parts of the commissioning process can be automatized and can generate benefits over the whole life of a building.

Using product specific simulation models in a tool for manual commissioning of air handling units

This paper presents a tool for manual commissioning of air handling units with the idea to combine the measurements with simulations. Thus the value of the measurements will increase.

The importance of control system commissioning for enchanced building operations

This paper points out the importance of control system in the overall operation of buildings and gives a description of practical issues in association with modern IT-oriented control systems.

Re-commissioning of the CAMET HVAC System: a successful case study

This paper after its first chapter about commissioning, presents the methodology used in the first re-commissioning phase of the CAMET HVAC system, with its principles and facts.Commissioning is a unique opportunity, for all partners concerned, to learn a lot about the realbehavior of a HVAC system and to restore people's confidence in air conditioning.

Hybrid model for building performance diagnosis and optimal control

This paper proposes a new hybrid model for automatic diagnostics and optimal supervisory control. Detailed physical parameters represent half of the model and identified parameters describe another half. That hybrid model can be used to predict accurately the cooling and heating energy consumption of buildings in a wide range of operation conditions.

AIVC/BETEC conference Washington - October 2003 -

This paper is the summary of the 2003 AIVC/BETEC conference with its different parts: Health and Building Science, Building evaluation, Single-building studies, Experimentation, Building science, Strategies and New directions.

Standard 62.2 approved-ASHRAE publishing residential IAQ standard

Standard 62.2. is the first and only recognized Indoor Air Quality standard for residential buildings in United States. It provides a variety of ways to improve at minimal cost the indoor air quality. This standard became official on October 2003. It may be applied to both new and existing houses.

Cooling performance of ground-coupled air intake ducts

In Norway and Sweden's schools, hybrid or natural ventilation with ground-coupled fresh air intake ducts (or culverts) is the popular way of conditioning air.The ground-coupled ducts are normally made of concrete and easily accessible for inspection and cleaning; they can be divided into two parts: the air-intake culvert and the air-distribution culvert. Measurements show that the use of ground-coupled ducts along with a suitable airflow regulation is a guarantee that the supply air is colder than room air.

Laboratory test of measuring hoods for supply air

Capture hoods are the most common measuring method for volumetric air flows from exhaust. The hoods have been continuously improved in order to prevent some deviations from calibrated values. In most cases a satisfactory accuracy can be achieved by this measuring method.

Indoor air pollution in urban buildings. A real threat for most of the world population

In developed countries, the concentrations of indoor pollutants are very similar to those outdoors. 3 basic strategies are proposed to reduce occupant exposure to indoor contaminants : 1. Building air tightening and pressure management2. Ventilation and air filtration3. Contaminant removalIn poor countries, the use of advanced ventilation and filtration techniques is not feasible at all, natural ventilation may be one of the more effective solutions
