Reconstruction for slovene ethnographic museum

Reconstruction of late 19 th century building for new Slovene Ethnographic Museum is presented. Interventions into building envelope and heating, cooling and lighting system from exhibits and visitors comfort and rational use of energy point of view were treated in the framework of EU and SI research programmes. An innovative heating-cooling system have been designed and tested.

European project HOPE (Health Optimisation Protocol for Energy-efficient Buildings)

In January 2002, a new European project named HOPE (Health Optimisation Protocol for Energy-efficient Buildings) started with 14 participants from nine European countries. The final goal of the project is to provide the means to increase the number of energy-efficient buildings that are at the same time healthy, thus decreasing the energy use by buildings, and consequently, resulting in a reduction of CO2 emissions from primary energy used for ventilation, heating and humidity control.

A heat and mass transfer analysis of cross-flow air-to-air total heat exchangers made of moisture-permeable paper

This paper presents an analysis of air-to-air total heat exchangers (heat and mass transfer) built up using moisture permeable paper (but impermeable to air molecules). Performance of 6 such total heat exchangers made of different types of paper were tested, in order to know their air leakage ratio and their energy saving ratio. An analysis is presented about the effect of leakage on energy recovery efficiency.

Energy and indoor environmental quality in relocatable classrooms

Four relocatable classrooms were designed, constructed and tested in Californian schools to demonstrate technologies that improve energy efficiency and indoor environmental quality. First results such as CO2 and particle concentrations are presented and discussed.

Guide pratique sur la modulation des debits de ventilation. Practical guide for the modulation of ventilation losses.

In order to adapt ventilation losses to the actual use of the premises one must aim to control the energy loads due to air renewal while at the same time ensuring the maintenance of good indoor air quality for comfort and hygiene for the occupants. The principle applications are premises presenting wide variations in occupation: number of occupants, but also effective hours of use. These systems are effective and economic, but they must be designed and installed correctly.

Design strategies for hybrid ventilation.

An innovative and potentially energy efficient approach to ventilating and cooling buildings is represented by hybrid ventilation. Discusses the application of hybrid ventilation strategies to building design in the USA.

AIRLESS: A European project to optimise indoor air quality and energy consumption of HVAC-systems.

The project aimed to conduct research on the reasons for pollution caused by HVAC systems. It was found that the reasons vary widely depending on the type of construction, use and maintenance of the system. Filter and ducts are major sources of pollutants, with humidifiers and rotating heat exchangers coming a close second. Heating and cooling coils are less of a problem, as is the effect of air flow. Puts forward a new maintenance guideline based on the existing VDI 6022.

A Building America prototype home packed with HVAC features.

Describes the features of a prototype home designed for a large builder in Michigan, USA, and the results of a series of DOE-2.1E energy simulations performed to assess the impact of various energy efficient aspects. The new features included: improvements to the thermal envelope and mechanical equipment; use of structurally insulated panels (SIPs) for the envelope; high performance, low-E argon-filled windows; a smaller, more efficient boiler; passive cooling design via a central stairwell with operable skylight; a unique mechanical ventilation system that can be scheduled and zoned.

Study on the specification of energy conservation of building external envelopes.

Energy consumption in building accounts for 30 percent of all the energy consumption of external envelope takes an important part. But in China, because of the insufficiency in thermal behaviour of building external envelope, indoor average heating temperature is low, while heating energy consumption per unit area is 2-3 times as much as that in developed countries under the same climate condition. In this paper, according to measurement and analysis on some kinds of walls, windows and roofs, the detail methods in energy saving of these structures are described.
