Energy Efficient Envelope Retrofit: a Case Study for a Bank Data Centre

This work is aimed at assessing the economical feasibility of a retrofit intervention consisting into the façade renovation of an office building, built in the 70s and located in Italy near Torino. The office building, characterized by high occupancy rate

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

Dynamic Moisture Behaviour of Materials for Integration into Whole Building Heat Air and Moisture Simulation

Indoor humidity is an important parameter influencing the occupants’ perception of indoor air quality, and is also a cause of harmful processes that may occur on surfaces of materials, such as cracking of walls or microbiological growth. Building material

Double-Skin Facade with Venetian Blind: Global Modelling and Assessment of Energy Performance

In this past decade, glazed façades use in new buildings has soared. Some of these façades, called "double skin façades", are made of internal and external glazing. As indicated by its name, "double skin façades" are a special type of envelope which air s

Direct Ground Cooling: Influence of Ground Properties on the Ground Heat Exchanger Size

In this paper the thermal behaviour of a direct ground cooling system located in Milano, Italy, isstudied by means of dynamic simulations performed in the TRNSYS environment. The simulationmodel consists of a reference building equipped with radiant panels connected to a vertical groundheat exchanger. Room thermostats and chilled surface condensation sensors provide system control.The ground heat exchanger size is adjusted in order to provide summer comfort conditions in thebuilding as well as sustainable operation over a long period.

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.

Development of a Method for Building Energy Diagnosis ; Application to an Existing Light Weight Building

The goal of this study, carried out on a wooden building, is to apply the methodology of identification inorder to obtain the physical parameters which characterize the thermal behaviour of the building. Theidentification of the system is the methodology of modeling the system starting from the experimentaldata.

Developing regulations to improve the energy efficiency of buildings in Arabian Gulf countries

As in other parts of the world, building legislation has been used since the 1980s by governmentbodies in the Arabian Gulf countries. These countries sought to reduce rising electrical consumption(6.7% per year) during the construction boom following the discovery of oil. Generally, however, theseearly regulations are limited in scope and have been implemented in a piecemeal manner across thedifferent countries.

Designing of a Guarded Hot Box

In 1997 several countries ratified the Kyoto protocol and so engage themselves to take into accountthe global warming, promote the sustainable development and act in order to reduce emission ofgreenhouse gases. Within this context, energy in buildings is known to be one of the first greenhousegases emitting sector. Consequently, determination of steady-state thermal transmission properties foreach kind of faade components becomes necessary in order to evaluate accurately energy loss, todevelop and enhance new products.

Daylighting in Schools: Technology, Energetical, Economical and Environmental Impact

The paper describes the transfer of technology appropriated from the social, economical andenvironmental point of view in schools at the province of Mendoza (South latitude 32, 53, Westlongitude 68 51, semi-arid climate) placed at the Southwest region of Argentina. The main aim of theinvestigation is to develop technologies which allow the maximum autonomy in terms of heating andlighting of the school buildings trough the use of solar energy.
