Employment, Remuneration And Workplace Report 2023, Roisin Murphy Dr

Reports

This report follows the previously published “Employment Opportunities and Future Skills Requirements for Surveying Professionals, 2018-2021” in which a significant shortage of property, land and construction professionals was projected. The current research has been undertaken against a backdrop of economic uncertainty due largely to Brexit, Covid-19 and the war in Ukraine.

The Irish economy rebounded well following the Covid-19 pandemic with low unemployment, moderate economic growth and solid Exchequer balances forecast in the medium term. On the downside, price inflation, fueled by soaring energy costs, have resulted in interest rates rising for the first time in over a decade which …

Sustainable Development In The Surveying Profession, Roisin Murphy Dr

Reports

The built environment sector provides the homes, workplaces, amenities and infrastructure to support everyday activity, and is a key contributor to economic growth and employment, but also to emissions and resource use. Construction, land and property surveyors are engaged throughout the built environment lifecycle and therefore, are uniquely positioned to lead and accelerate the transformational change required to ensure a sustainable built environment. The United Nations Sustainable Development Goals (UNSDGs) provide a blueprint exhibiting social, economic and environmental goals to be considered as a system of interrelated objectives. Attainment of the SDGs requires a global approach, which is entrenched in …

Rent Certainty Is Not Rent Control, Tom Dunne

Reports

The housing crisis and the debate about rent control should result in a beneficial change to the regulation of the sector but the opportunity could be lost for want of clarity of thinking about the nature of rent certainty and the distinction between it and rent control. At present rent is regulated by the Residential Tenancies Act 2004 (RTA 2004) which provides that rent can only change once a year and cannot be more than the market rent. Many argue a greater degree of rent certainty is required and that rent should not be allowed to increase by more than …

Renting Trouble: Current Government Policy Of Relying On The Private Rented Sector To Deliver Social Housing Is Unlikely To Succeed, Tom Dunne

Reports

A review of the history of housing in Ireland shows that owner occupancy and social housing were policy choices by successive governments. Owner occupancy was heavily supported through a system of grants and tax breaks and social housing was directly provided through local authorities at subsidised rents. In recent years policy has changed and tenure neutrality is now guiding the government’s attitude to housing. This is a significant change which has not been sufficiently discussed and has consequences which are not appreciated. Relying on the market to provide rental housing for people on low incomes and who may be in …

Link Levy To Services- Not Urban Middle Class Assets, Tom Dunne

Articles

Paying any tax is an unwelcome burden, but in Ireland many have a particular aversion to taxes on their homes. We are not alone in this. Elsewhere, taxes on homes are also unpopular; witness the People's Initiative to Limit Property Taxation which forced the California state government to cut property taxes. Nevertheless, residential property taxes remain an almost universal feature of developed countries because of compelling economic arguments for them. Also, local property taxes are regarded as the best means of funding local government.

Rarely, it seems to me, is there such a distance between what the public wants and …

Sensitivity Studies Of A Low Temperature Low Approach Direct Cooling Tower For Building Radiant Cooling Systems, Medhi Nasrabadi, Donal Finn, Ben Costelloe

Conference Papers

Recent interest in cooling towers as a mechanism for producing chilled water, together with the evolution of radiant cooling, have prompted a review of evaporative cooling 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. The feasibility of this concept depends largely however, on achieving low approach water temperatures within an appropriate cooling tower, at acceptable levels of energy performance. Previous experimental work for a full scale evaporative cooling system has shown that it …

Mathematical Modelling Of A Low Approach Evaporative Cooling Process For Space Cooling In Buildings, Medhi Nasrabadi, Donal Finn, Ben Costelloe

Conference Papers

This paper describes a mathematical model of a low approach open evaporative cooling tower for the production of high temperature indirect cooling water (14-16°C) for use in building radiant cooling and displacement ventilation systems. There are several potential approaches to model evaporative cooling, including: the Poppe method, the Merkel method and the effectiveness-NTU (ε-NTU) method. A common assumption, applied to the Merkel and ε-NTU methods, is that the effect of change in tower water mass flow rate due to evaporation is ignored, which results in a simpler model with reduced computational requirements, but with somewhat decreasedaccuracy. In this paper, 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. …

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.

Land Values As A Source Of Local Government Finance, Tom Dunne

Books/Book Chapters

Funding local government has been a permanent feature of debates about public policy in Ireland and Many feel that the balance of power between local and central government is weighted too much in

This paper suggests that the concept of economic rent, on which the justification for property taxes rests and its relevance to the property market in a modern, economically successful and urbanised Ireland, needs to be vented, discussed and debated.

The proposition is that if a greater understanding was created about the economic characteristics of landed property both value capture and local property taxes would achieve greater public …

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 …

Evaporative Cooling Availability In Water Based Sensible Cooling Systems, Ben Costelloe, Donal Finn

Conference Papers

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, such as chilled ceilings, which require a supply of cooling water at 14 to 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 or wet bulb temperature. Recent research in this area has shown that it …

The Secondary Retail Market - A Viable Option?, Elaine Murphy

Masters

The secondary retail market in Dublin has dramatically altered over the last four years. Indeed, the entire retail market in Dublin and countryside has witnessed a substantial upsurge in activity over the last four years. On Grafton Street retail Zone A rents are breaking £2,153 per square metre (£200 per square foot) barrier and premiums are in the region of £300,000 -£400,000. There is currently a shortage of good retail investment opportunities on Grafton Street, which is leading investors to turn to Dublin’s other prime street, Henry Street. Over the last year Zone A rents on Henry Street have increased …
