UK Climate change programme and domestic sector end-use efficiency

Information in the UK Climate Change Programme suggests that carbon savings in the domestic sector from end-use efficiency improvements could amount to some 4.7MtC/yr in 2010, based on allowances for improvements to the building regulations, residential energy efficiency improvements and appliance standards and labelling. This paper discusses detailed scenarios that have been developed using the BREHOMES model of the energy use of the housing stock to study the implications of this level of saving.

Design guidelines for the Efficient Integration ofRenewable Energy systems and techniques in newbuild settlements in Europe

The White Paper on renewable Energy proposes market measures for fair access to the electricitymarket, fiscal and financing measures, a bio-energy initiative and improved building regulations. Thebuilding's sector represents 20 to 45% of the total energy consumption in the various European countries. A project called RESSET has been undertaken with the aim to study and propose globalstrategies, tools and guidelines that will promote the efficient and cost effective global implementation of Renewable Energy Sources systems and techniques in new-build settlements in Europe.

Energy in air-handling units - results of the AIRLESS European project.

In this paper the authors present the results of the European AIRLESS programme whose aim was to identify the pollution sources in air-handling units, and then avoid or eliminate this pollution. The authors propose several energy efficient ways to provide good indoor air and efficient indoor environment conditioning.

Pressure controlled variable air volume system

Designing an HVAC system has different aims, the first one is to satisfy the user with a long-term functioning system in the most energy efficient way and the second is to increase the supply air flow. So the main objective of this paper is to give the fundamentals for a system design that takes into account the 3 factors. The benefit of a pressure controlled variable air volume (VAV) system is presented .

Information from the EC MATHIS project

This project lasted from February 1998 to January 2001. The main result from "MATerials for Healthy Indoor Spaces and more energy efficient buildings" project is SOPHIE : a database of indoor pollutants sources, a useful tool for the selection of low polluting materials and components. Other interesting results have been obtained :
- SOPHIE protocol testing for building material
- A new model for IAQ and energy efficiency
- 3 new methods and first results concerning study sorption and diffusion properties of VOCs in the materials

Supply air CO2 control of minimum outdoor air for multiple space systems

Supply air CO2 control (SACO2) is a technique for measuring the outdoor air fraction in the supply air and controlling the outdoor air intake. It is applicable to recirculating systems serving multiple places where ventilation targets are based on outdoor airflow rate per person. SACO2 offers significant benefits : energy savings, simple maintenance, adequate ventilation and ability to measure and record performance.

CO2-Based demand control ventilation. Do risks outweigh potential rewards ?

In this article, the sources of risk using DCV (demand control ventilation) are examined along with the components typically and the possible ways to minimize risk without sacrificing potential energy savings.

The impact of energy efficient refurbishment on the airtightness in english dwellings

Fan-pressurisation method was used to test the air infiltration rate of 191 dwellings in England. All tested homes were either pre or post the introduction of energy efficient retrofit measures such as cavity wall insulation, loft insulation, draught stripping and energy efficient heating system. Results show that the average air infiltration rate of the post dwellings is only marginally lower by 4% compared to the pre dwellings.

Thermal performance characteristics of an energy-efficient, healthy house

A collaborative effort between Oak Ridge National Laboratory and Tuskegee University has resulted in an energy-efficient, healthy house that is built on Tuskegees experiment station farm to conduct various energy efficiency and indoor air quality studies. The house is well insulated and possesses other energy-efficient features, such as airtight construction, reflective roofing, and unventilated crawlspace. The energy efficiency and thermal performance of the house are investigated in view of electric power consumption as well as indoor and outdoor temperature and relative humidity data.

Indoor air quality of an energy-efficient, healthy house with mechanically induced fresh air

Issues associated with indoor air quality (IAQ) and its impact on occupant health have prompted research into the design and construction of healthy houses. Most of the houses constructed have been upscale housing. An affordable, energy-efficient, healthy house was built at Tuskegee
