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

Development of a Web-Based Building EnergyPerformance Benchmarking System

The purpose of this paper is to introduce Energy Smart Tool, a new web-based building energyperformance benchmarking system developed recently by Energy Sustainability Unit of NationalUniversity of Singapore. It provides users with direct comparisons of their buildings energyperformance to other similar facilities, which helps to identify the position their facilities, and to setenergy saving targets. A general discussion of the benchmarking procedure is given.

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

In March 2003 a “CO2 - Saving Potential when using Pipe Insulation” study [1], sponsored by Armacell - worldwide producer of flexible pipe insulation products, was published by the Centre for Environmentally Sustainable Buildings (ZUB) in Kassel. The aim

A Quality Assurance System for Indoor Environment and Energy Use

To achieve the intended results of building, managing and using a property requires knowledge,continuity and communication, which can be assured by a dynamic and flexible quality assurance(QA) system. Such a system, intended to ensure high-quality indoor environmental conditions, hasbeen developed and successfully applied over the last ten years. However, although clients have beenvery satisfied with the QA system and its results, the pressure for energy efficiency improvement hasincreased.

Energy assessment for a new urban settlement

The paper concerns the definition of guidelines in the design of a new urban settlement, based on system energy utilization and building environmental impacts and sustainability improvement. The study refers to a 160000 m2 area sited on the outskirts of Carmagnola, a city close to Torino, where the municipality decided to locate about 1260000 m3 of commercial buildings: offices, shopping centres, a trade fair area, a cattle market, a multi-hall cinema, hotels, restaurants, industrial sheds.

The Thermal Performance of Ventilated Roofs

The potential for passive cooling of roof slabs incorporating an air cavity is important with respect tothermal comfort. Roof systems in traditional buildings, incorporated a ventilated roof or an air cavity.The concept has been proposed again in contemporary buildings in the construction of roof slabs,using a modular formwork system, where the cast in situ concrete slab is isolated from the screed with the introduction of a ventilated air space. The cavity is primarily intended to curtail the conduction and inward radiation of heat from the intense solar insolation on the concrete roof.

Sustainable Energy Management Based on the European Energy Performance Building Directive (EPBD)

The EPBD prescribes an energy performance certificate for buildings. According to the nationalimplementations of the EPBD for non-domestic buildings the specific data of the building will begathered during the certification process and combined into a multi zone model describing buildingand building systems from an energetic point of view.

Results of Monitoring a Naturally Ventilated and Passively Cooled Office Building in Frankfurt A.M., Germany

In this article the concept of a new energy-efficient office building and results of a 3-year monitoringare described. The monitoring was performed within the German funding programme ENOB.In this building most of the offices are naturally ventilated and passively cooled. Another focus of theenergy concept is on regenerative heating.Monitoring results show that the integrated planning enabled a very low consumption of energy forheating, ventilation, cooling and lighting.

Monitoring and Data Analysis of two Low Energy Office Buildings with a Thermo-Active Building System (TABS)

A promising approach to reduce the primary energy demand of office-buildings without violatingthermal comfort is passive cooling by thermo-active building systems (TABS). The presented studyintroduces two low-energy office buildings within the framework of the German programme ENOBwhich are conditioned by TABS mainly supplied by geothermal energy.

The Design of an Energy Efficient Highly Glazed Office Building

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned.
