Addressing Low Heat Pump Heating System Sales In The Uk, Ben Costelloe

Articles

The replacement of existing fossil fuel boilers with heat pumps is seen as a key measure in the decarbonisation of heating systems and addressing climate change. This policy however, is currently failing in many Western European states, particularly in the UK. The many reasons for this situation are examined. However, the age of UK housing stock and particularly the high number of dwellings built prior to the introduction of building insulation regulations in 1980, are key. To maintain the running cost of air source heat pumps competitive with those of the gas boilers they generally replace the heat pump lift …

A Stereotomic Struggle, Jim Roche

Articles

Stone in architecture has “territorial and political implications” as its use and designation impact the human rights of the indigenous population. The craft of stereotomy is not just bequeathed from the Crusaders or more recent imperial colonists but has a diverse blended history that is deeply ingrained in Palestinian built culture. Such theses inform the experimental work of Elial and Yusef Anastas, two brother architects who operate from Bethlehem what they term a counter hegemonic practice with the stated aim of “decolonising architecture”.

Building Performance - Societal Drive, Programme And Symposium, Joseph Little, Patrick Daly

Articles

Society is increasingly looking at the construction industry to mitigate the environmental crisis and solve the housing crisis through wholesale embrace of three broad sets of challenges. The MSc in Building Performance (Energy Efficiency in Design) (MSc BP(EED)) was created in 2017 to provide significant upskilling in the knowledge, skills, and software applications of building design professionals so that they can meet these challenges, while creating compliant, sustainable, super-low energy, new and renovated buildings. The delivery of the programme supports upskilling of employed building design professionals at Masters level, encouraging a minority to develop their capacity and interest in research …

The Impact Of The Ambient Environment And Building Configuration On Occupant Productivity In Open-Plan Commercial Offices, Mark Mulville, Nicola Callaghan, David Isaac

Articles

Purpose

This paper sets out to understand the impact of the ambient environment on perceived comfort, health, wellbeing and by extension productivity in the workplace.

Design/methodology/approach

The research combined an occupant survey considering satisfaction with the ambient environment, health and wellbeing and workplace behaviour with the monitoring of ambient environmental conditions.

Findings

The paper demonstrates that the ambient environment can have a significant impact on occupant comfort, health and wellbeing, which in turn has implications for built asset performance. Within the ambient environmental factors considered, a hierarchy may exist with noise being of particular importance. Occupant behaviour within the workplace …

Energy-Saving Occupant Behaviour In Offices: Change Strategies, Mark Mulville, Keith Jones, Gesche Huebner, Joanne Powell-Grieg

Articles

As regulated energy consumption in buildings is reduced, the proportional importance of unregulated energy consumption increases. Reducing unregulated energy use in the commercial office requires an understanding of the factors that influence workplace behaviour. To date these factors have been assumed to be similar to those that influence behaviour in the home. However, the social dynamics of the workplace are different to those in the home. This study examines the degree to which theories of behaviour change generated largely in a domestic building setting could be used as the basis for designing interventions to reduce unregulated energy consumption in the …

Thermal Energy Storage In Building Integrated Thermal Systems: A Review. Part 2. Integration As Passive System, Dervilla Niall, Sarah Mccormack, Philip Griffiths, Luisa Cabeza, Lidia Navarro, Albert Castell, Alvaro De Grazia, Maria Brown

Articles

Energy consumption trends in residential and commercial buildings show a significant increase in recent decades. One of the key points for reducing energy consumption in buildings is to decrease the energy demand. Buildings envelopes are not just a structure they also provide protection from outdoor weather conditions always taking into account the local climate. Thermal energy storage has been used and applied to the building structure by taking advantage of sensible heat storage of materials with high thermal mass. But in recent years, researchers have focused their studies on the implementation of latent heat storage materials that if well incorporated …

The Latest Homebond House Building Manual : A Critique, Joseph Little

Articles

The Homebond House Building Manual had the distinction of being called the ‘bible’ for many building during the boom. It was a commonly‐used reference book, even for many builders and architects who never built housing estates and therefore had little need of a Homebond guarantee. One might design a construction detail of a dwelling differently, but one did it with an awareness of what the manual showed. It gave the insurance scheme great credibility and standing. This architect remembers reluctantly getting involved with an external wall insulation self‐build project in rural Ireland in 2006 (far beyond his normal travel distance) …

Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu

Articles

Although embodiedCO2-eq analysis has seen recent developments as evident in the establishment of the ISO14040 and 14044 LCA standards, it is recognized that due to weaknesses in gathering data on product-related emissions,embodiedCO2-eq values are probabilistic. This paper presents a stochastic analysis of hybrid embodied CO2-eq in buildings to account for this weakness in traditional methods and, by way of example, applies it to an Irish construction-sector case study. Using seven apartment buildings, 70,000 results are simulated with Monte Carlo analysis and used to derive probabilistic and cumulative embodied CO2-eq intensity distributions for apartment buildings in Ireland. A Wakeby distribution with …

Thermal Bridging - Understanding Its Critical Role In Energy Efficiency, Joseph Little, Beñat Arregi

Articles

Plane element heat loss[1] and thermal bridging[2] together constitute all the conduction heat loss (measured in W/K, watts per kelvin) through the thermal envelope[3] of a building. Perversely insulating the plane elements more and more without carefully dealing with junctions can lead to a significant increase in thermal bridging heat loss. This is often more significant in poorly thought-out energy-focused retrofits than in existing or new buildings.

Tracking The Use Of Leed® In Facilities For Higher Education, Shannon Chance

Articles

America’s 4391 institutions of higher learning own roughly 240,000 buildings according to The Carnegie Foundation for the Advancement of Teaching (2009) and the United States Green Building Council [USGBC] (n.d.). Most of these buildings’ designs reflect a time when energy was cheap and material abundant. Throughout the past century, building designs frequently ignored their surroundings, usurped energy at appalling rates, and did little to teach inhabitants respect for the environment

Top Tips For Domestic Refurbishment, Joseph Little

Articles

1) It stands to reason that insulating a wall should not affect its strength or longevity, nor should it result in a buildup of moisture (inter-stitial condensation) or mould. However the Industry is currently gripped with a desire to insulate to the highest standard (U-value) at the lowest financial cost, as quickly as possible, with little thought of these issues. An appropriate, robust solution must take the original wall, the occupant’s health, the room’s function and even the building’s location into account.

Breaking The Mould 5 : Comparative Simulation Of Internal Insulation Systems, Joseph Little

Articles

In the last edition of Construct Ireland ‘Breaking the Mould IV’ established the standard that should be used to evaluate thermal upgrades of single leaf walls, described steps to physically prepare the wall, explained some of the mechanisms that affect the likelihood of mould and gave criteria for judging the simulations outputs. The next step is to simulate a number of permutations of typical internal insulation systems using WUFI Pro under IS EN 15026.

Breaking The Mould 4 : Condensation Risk Analysis – The Standards And The Issues, Joseph Little

Articles

The ‘Breaking the Mould’ series of articles was written to explore the range of issues associated with upgrading single leaf walls with a focus on occupant and building health as much as energy, just as the Home Energy Saving Scheme was launched. A year on from the first article the need for greater understanding and clear guidance for the Industry is greater than ever. This is because the Government’s ‘Energy Demand Reduction Target’ (EDRT), under the 2006 EU ‘Energy Services Directive’, is bringing energy utilities (e.g. ESB, Bord Gáis) into the refurbishment market.

The Thinking Hand: Book Review, Jim Roche

In this new book Juhani Pallasmaa continues his phenomenological exploration begun in ‘The Eyes of the Skin (2005)’, with the ‘Thinking Hand’ here proffered as a metaphor for his contention that all our senses, have innate imbedded crucial skills which help us perform the most basic daily tasks – and to create inspired works of art and architecture.

Breaking The Mould 3, Joseph Little

Articles

This article is the third in a series looking at thermal upgrades to single-leaf walls of existing houses. The theme for this article was intended to be an analysis of various drylining options for brick and rubble-built walls of older properties. That will follow. The following events forced a change in focus.

Breaking The Mould 2 : An Analysis Of Single-Leaf Insulation Upgrades, Joseph Little

Articles

This article is the second in a series looking at thermal upgrades to single-leaf walls of existing houses. It compares a range of ways of upgrading masonry single-leaf walls, particularly the ubiquitous hollow block wall, and the impact of those decisions on moisture content, wind- and airtightness, cost and heating. Future articles will look at various drylining approaches for a range of walls including brick walls of various widths.

Breaking The Mould 1 : A Study Of Condensation In Single-Leaf Concrete Wall Upgrades, Joseph Little

Articles

This article is the first of a series looking at upgrade options and issues associated with single-leaf walls of existing houses. This article will focus on insulated drylined concrete block walls of the ubiquitous housing estate house. This will include the findings of software that dynamically models moisture movement through the wall over several years. The article following this will look at a range of options for replacing existing drylining or installing drylining where it never was before, be that for a solid block wall of a 1950s house or a solid brick wall of an 1850s house.

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 …

Proposal For Using A Studio Format To Enhance Institutional Advancement, Shannon Chance

Articles

Universities today need to become quicker on their toes. They must continually scan the environment and seize emerging opportunities – and institutional advancement must lead this effort. An unfortunate number of institutional advancement operations are ill equipped for the task at hand. Many suffer from high staff turnover and overly hierarchical systems that refl ect excessive fragmentation and compartmentalization. They inadvertently perpetuate stifl ing and unnecessary bureaucracy. Organizing advancement efforts around the metaphor of the design studio or creative workshop promises to (a) pool talent, (b) cultivate collaboration, and (c) align diverse but related interests in order to promote fruitful …

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 …
