Heat Transfer Correlations For Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Articles

The experimental performance of an open industrial scale cooling tower, utilising small approach temperature differences (1–3 K), for rejection of heat at the low water temperatures (11–20 °C) typical of chilled ceilings and other sensible air–water heat dissipation systems in buildings, is examined. The study was carried out under temperate maritime climatic conditions (3–18 °C wet-bulb temperature range). Initially a theoretical analysis of the process at typical conditions for this climate was conducted, which indicated that a water to air (L/G) mass flow rate ratio of less than 1.0 was required for effective operation. Consequently for these low L/G ratios, …

Frame It - Thoughts On Education, Reducing Carbon And Vapour, Joseph Little, Robbie Cousins

Articles

Joseph Little believes timber frame can be the backbone of a new generation of low-carbon, energy-efficient housing, and be used as an intelligent response to Climate Change and fuel prices. But he tells Robbie Cousins that timber frame manufacturers, suppliers and architects need to gear-up and work more closely together if the true potential of this vision is to be realised.

Joseph Little’s chief bugbear is poor construction standards & details on site and the core of this issue is how the knowledge set of architects and builders and how standards are controlled. The seeds of this idea may have …

The Regenerative Rebuilding Strategy For Sustainable Coastal Communities. An Architectural Thesis And Case Study Of Rebuilding Post-Tsunami Sri Lanka., Kristina Iverson, Shannon Chance

Conference papers

Developments are occurring at a rapid pace along coastlines all over the world. In fact a full two-thirds of the world’s population, or 4 billion people, live within 250 miles of a coast1. In the United States architects have recognized the negative effects of existing building practices on beaches. In fact, designers have eagerly adopted methods of “sustainable design” to band-aid the problem. While seemingly an improvement upon past building practices, current movements in sustainable design focus on slowing down the degradation to the beach environment instead of encouraging healing practices. If we are to sustain the existence of both …

Thermal Effectiveness Characteristics Of Low Approach Indirect Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Articles

Meteorological enthalpy analysis of temperate and maritime climates above latitude 45°N suggests that the water-side evaporative cooling technique has considerable unrealised potential with contemporary “high temperature” building cooling systems—such as chilled ceilings and displacement ventilation. As low approach conditions are the key to exploiting the cooling potential of the ambient air, thermal performance at such conditions needs to be investigated. To address the research issues, an industrial scale test rig, based on a low approach open cooling tower and plate heat exchanger and designed to maximise evaporative cooling potential, has been constructed. The thermal effectiveness of such systems (as a …

Thermal Performance Of Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Conference Papers

Meteorological enthalpy analysis of temperate and maritime climates above 45˚N suggests that the water-side evaporative cooling technique has considerable unrealised potential with contemporary "high temperature" building cooling systems - such as chilled ceilings. As low approach conditions are the key to exploiting the cooling potential of the ambient air, thermal performance at such conditions needs to be investigated. To address the research issues a test rig, based on an open cooling tower and plate heat exchanger and designed to maximise evaporative cooling potential, has been constructed at DIT. A combination of experimental measurement and analysis is used in the investigations. …

A Critical Appraisal Of The Opportunities Currently Available For A More Energy Conscious Approach To Residential Building In Ireland, John Mcdonagh, Louis Gunnigan

Conference papers

This paper focuses on the particular advantages which off-site housing construction has over the more traditional methods of building especially where the efficient use and conservation of energy is concerned. It will explain why modern innovative methods of house construction not only have a clear advantage environmentally (big reductions in CO2 emissions) but also deliver substantial benefits to the end user or householder especially in the form of lower energy bills.

The ecological argument for off-site systems is a very powerful one but on its own is still unlikely to be the prime driver for widespread implementation. That growth is …

The Extraction Of A Road Centre Line From Airborne Laser Scanning Data, Patrick Doyle

Masters

Due to its speed and accuracy the Global Positioning System (GPS) is widely used as a data collection tool. Problems however can occur when this GPS data is used in conjunction with existing National Mapping Agencies (NMA) vector databases that are not of comparable accuracy. Shifts and misalignments of the datasets can occur. In talks with the Irish mapping agency, Ordnance Survey Ireland (OSi), prior to this project, it viewed with interest the possibility of using Airborne Laser Scanning (ALS) data as a general quality indicator of existing vector databases. The aim of this research was to extract the centre …

Construct Ireland - Lime-Hemp - A Potential Solution To A Concrete Problem, Joseph Little

Articles

This article is intended to act as an exploration and provocation. Why do we build the way we do, what effect does that have? Could we for instance, design and specify buildings that actually benefit the Environment rather than burden and pollute it as currently. Is it possible that the construction of a house could absorb CO₂ thereby transforming new housing estates or apartment buildings into giant absorbers of carbon dioxide? Imagine Ireland being able to count commercial constructions or new housing among its ‘carbon sinks’, in place of Siberian forests or the carbon credits that the Government will …

Thermal Efficiency Characteristics Of Indirect Evaporative Cooling Systems, Ben Costelloe, Donal Finn

Conference Papers

Recent developments in enhancing heat transfer in cooling towers, together with the success of chilled ceilings, have prompted a review of the evaporative cooling technique. in temperate maritime climates. The thermal efficiency of such systems is a key parameter, as a measure of the degree to which the system has succeeded in exploiting the cooling potential of the ambient air. This paper presents the results of experimental research into the thermal efficiency of a water-side open indirect evaporative cooling test rig designed to achieve low (1-4 K) approach conditions. Secondary efficiencies in the range 0.24-0.76 have been achieved.

Property Value Assessment And The Irish Eia Process, Siobhaun Cawley

Masters

Environmental Impact Assessment (EIA) provides for the assessment of the likely significant effects of a proposed development in the environment. Due to the ambiguous nature of the legislation on EIA, there are widely differing views as to whether the impact of a proposed development o surrounding property values should be considered as part of the EIA process. The primary objective of this thesis was to establish if property values should be considered within the Irish EIA process. In this regard, the most relevant provisions of the EC Directive 97/11/EC and the corresponding Irish legislation (Part X of the Planning and …

Experimental Energy Performance Of Open Cooling Towers Used Under Low And Variable Approach Conditions For Indirect Evaporative Cooling Of Buildings, Ben Costelloe, Donal Finn

Articles

The success of chilled ceilings and displacement ventilation systems as a means of sensible cooling in buildings has prompted a review of evaporative cooling technology as an effective means of generating the required cooling water. When such cooling water is generated at low approach conditions (2–5 K), at the higher temperatures required in these systems (14–18°C), very high levels of availability result. In many north western European locations the levels of availability are such that the prospect of supplanting rather than simply supplementing the refrigeration system, for sensible cooling purposes, arises. The viability of the technique, however, largely depends on …

Indirect Evaporative Cooling Potential In Air-Water Systems In Temperate Climates, Ben Costelloe, Donal Finn

Articles

Recent developments have prompted a review of evaporative cooling technology as an effective means of cooling modern deep plan buildings. Prominent among these developments is the success of high temperature sensible cooling systems, particularly, chilled ceilings, which require a supply of cooling water at 14–18 °C. Crucial to the success of evaporative cooling technology, as a significant means of cooling in modern applications, is the ability to generate cooling water, in an indirect circuit, at a temperature which closely approaches the ambient adiabatic saturation temperature (AST) or wet bulb temperature (WBT). Recent experimental research has demonstrated that it is technically …

Research Into Evaporative Cooling Of Buildings In Maritime Climates, Ben Costelloe, Donal Finn

Reports

Concern with environmental emissions has focused attention on traditional forms of energy use in buildings, with a view to reducing and making more rational use of energy consumption. One area of concern is the traditional, refrigeration based, commercial air conditioning system, which has high levels of electrical power consumption in fans and refrigeration compressors. There is also concern among building owners and design teams, supported by the PROBE series of post occupancy studies, conducted by the CIBSE, that many buildings, with traditional forms of air conditioning, under perform in terms of occupant satisfaction, ease of operation and control, maintenance costs …
