The Energy Performance Of Buildings Directive: Where Are We Going?, Hywel Davies
The Energy Performance Of Buildings Directive: Where Are We Going?, Hywel Davies
SDAR* Journal of Sustainable Design & Applied Research
The EU adopted the Energy Performance of Buildings Directive in 2003 to help to measure, manage and reduce energy consumption and consequential carbon emissions related to buildings. It introduced the concept of energy certificates for buildings on construction, sale or rent. It required energy certificates for display in many public buildings across Europe and introduced regular inspections of heating and air conditioning systems. The Directive was recast in 2010, to include a number of amendments aimed at improving the effectiveness of the legislation. The Directive is now being reviewed again and the European Commission, the Parliament and the Council of …
The New Irish Building Regulations Part L:The Impact On City Centre Developments, Mona Holtkoetter
The New Irish Building Regulations Part L:The Impact On City Centre Developments, Mona Holtkoetter
SDAR* Journal of Sustainable Design & Applied Research
An update of the Building Regulations Technical Guidance Document Part L has been announced by the Department of Housing for the end of 2017. This update introduces the requirements for Nearly Zero Energy Buildings (NZEB) for buildings other than dwellings and embraces a minimum renewable energy contribution. This paper is based on the draft Part L 2017 and explores the potential impact the update has on current building design strategies, using a Dublin city centre office building as an example. The paper outlines the simulation procedures using a currentlyavailable software program and compares the building design strategies for compliance with …
Energy Audit Of A Fitness/Leisure Centre, Paul Wynne, Eoin D. Mclean
Energy Audit Of A Fitness/Leisure Centre, Paul Wynne, Eoin D. Mclean
SDAR* Journal of Sustainable Design & Applied Research
This paper aims to investigate the energy performance of a fitness/leisure centre. A detailed energy audit has been conducted to determine the energy consumption of the building. Through the collection and analysis of data, the energy performance and Energy Performance Indicators (EnPIs) have been identified. This research indicates that an energy audit can lead to identifying significant energy savings potential in a building. Energy saving opportunities have been identified with a potential to save 158,906kWh of electricity, 81,201kg of CO2 and potentially saving up to e51,230 per annum. A combined heat and power (CHP) plant could yield savings of up …
A Case Study Of The Omani Electricity Network And Readiness For Solar Energy Integration, Eugene Coyle
A Case Study Of The Omani Electricity Network And Readiness For Solar Energy Integration, Eugene Coyle
SDAR* Journal of Sustainable Design & Applied Research
In this paper a study is made of the electricity network of the Sultanate of Oman. The electricity industry of Oman currently relies on almost 100% fossil fuels – with natural gas (97.5%) and diesel oil (2.5%) being the primary sources of electricity generation. This reliance is expected to change significantly in the coming years. Harnessing solar energy (and wind energy) will help to significantly reduce the country’s carbon emission footprint whilst enhancing intra-structural development and ensuring economic stability. Solar energy density levels in Oman are among the highest in the world. The country receives an extensive daily solar radiation …
Key Factors Dictating Excessive Lighting Energy Consumption In Schools: A Post-Occupancy Analysis, Roderic Bunn, Peter Raynham
Key Factors Dictating Excessive Lighting Energy Consumption In Schools: A Post-Occupancy Analysis, Roderic Bunn, Peter Raynham
SDAR* Journal of Sustainable Design & Applied Research
Good practice in lighting energy consumption in schools is regarded to be around 13 kWh/m2 per annum (CIBSE LG5, 2011). However, recent post-occupancy evaluations reveal lighting energy consumption in schools to be above 30kWh/m2 p.a., despite the use of energy efficient lamps, switching based on infrared presence/absence detection, and digital controls for daylight-linked dimming. To identify causes of excess energy consumption for lighting, this study undertook detailed post-occupancy field measurements of the lighting consumption of two recently-completed K schools – a small primary and a large secondary – equipped with digitally-addressable lighting interface (DALI) systems. Instrumentation of individual light fittings …
An Examination Of A New Interior Lighting Design Methodology Using Mean Room Surface Exitance, Kevin Kelly, Antonello Durante
An Examination Of A New Interior Lighting Design Methodology Using Mean Room Surface Exitance, Kevin Kelly, Antonello Durante
SDAR* Journal of Sustainable Design & Applied Research
This paper disseminates both new and previously-published findings to show how a whole new lighting design system can be easily implemented, whereby interior lighting is designed for appearance rather than visual performance alone. This paper presents the findings of multiple PhD research undertaken in the Dublin Institute of Technology that started in 2011 and continues. This paper is presented for a building services engineering audience and emphasises why there is a need for change, what it is that is proposed, the implications for existing practice, the benefits of the new design methodology, and the challenges remaining before it can be …
