BUILDINGS ENERGY CONSERVATION: EUROPEAN COUNTRIES’ EXPERIENCE

As presented by the Energy Green Paper “A European Strategy for a sustainable, competitive and Secure Energy” (1), Europe has entered a new energy era. Global demand is increasing within a framework of high and unstable prices. Emissions of greenhouse gas

CO2 emission and energy saving potential through correct pipe insulation in cold applications

In November 2006 a “CO2 emission and energy saving potential through correct pipe insulation of space heating and domestic hot water distribution systems in the new and existing buildings.” paper [3], sponsored by Armacell - worldwide producer of flexible

Building Blueprint: Endorsement Schemes for Building Energy Efficiency Improvements in the EU25

Although there is significant support among policy makers and politicians for energy efficiencyimprovements in buildings, there remains a lack of understanding of what policies (regulatory,economic, communicative and organisational) can deliver these changes on the ground. The blueprintstudy attempts to address this gap.

SIMUBEMS: An educational tool on control techniques

This paper describes an educational tool developed at LASH ENTPE (France) laboratory. Theobjective of this tool, called SIMUBEMS, is to familiarize ENTPE students with control techniques andallows performing simulations in order to test heating and ventilation control strategies.An office building equipped with an HVAC system has been used to carry out the simulations. Themodelled zone is 9 m long, 6 m large and 2.5 m height and has large glazed faade.

Increased Energy Efficiency and Improved Comfort

This paper summarises the work of the LowEx co-operation /1/. The aim was to promote rational use ofenergy by encouraging the use of low temperature heating systems and high temperature cooling systems ofbuildings. These systems can use a variety of fuels and renewable energy sources. Energy is used efficientlywhile providing a comfortable indoor climate. Exergy defines the quality of energy and is a concept fordesigning and assessing different heating and cooling systems. Application of exergy analysis into buildingshas not been common before.

Exergy Use in the Built Environment Basics and Analyses

It is often claimed that energy is consumed; this is not only done in everyday conversation but also inscientific discussions associated with energy and environmental issues. This claim conflicts with thefirst law of thermodynamics stating that the total amount of energy is conserved, even though forms ofenergy may change from one to another.

Best Practice Guidelines for Double Skin Facades

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned. Therefore more and more of these buildings are being built with doubleskin facades, which can provide: a thermal buffer zone, energy savings, wind protection with openwindows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, pollutantprotection with open windows, nocturnal cooling and a site for incorporation of PV cells.

Best Practice for Double Skin Facades The BESTFACADE Project

Double skin facades have become a major architectural element in office buildings over the last 15years. A double skin facade can provide a thermal buffer zone, solar preheating of ventilation air,energy savings, sound protection, wind and pollutant protection with open windows and nocturnalcooling. Commercial buildings with integrated double skin facade can be very energy efficientbuildings with all the good qualities listed above.However not all double skin facades built in the last years perform well.

Towards Low-Energy Factory Buildings (A Case Study)

This paper presents a case study of a typically poor energy performing factory building singled outfrom nation-wide study on factory buildings for improving energy performance. Short term energymonitoring has shown that lighting system is the main energy consumer of landlord area energyusage in these naturally ventilated factory buildings. It aims to maximize significant energyperformance upgrading opportunities in the lighting system and explore the use of photovoltaics toachieve low-energy factory buildings.

Energy and Exergy Analysis of Integrated Systems of Buildings and District Energy Plants

The purpose of the paper is to influence governments throughout the world to achieve massiveimprovements in energy and exergy performance in their respective countries by legislation and otherpolicy instruments keyed to the overall or integrated energy and exergy performance of energytransformation systems.Energy transformation systems include: all types of buildings; electric, heating, and cooling districtpower plants; water treatment plants, energy and water distribution systems; cars, trucks, buses,motorcycles, trains, planes and other powered transportation systems; and manufacturing pr
