Predicting Building Energy Performance: Leveraging Bim Content For Energy Efficient Buildings, Eddie Villanueva Aquino

Master's Theses

Reducing and managing the environmental impacts of building structures has become a priority of building stakeholders and within the architecture, engineering and construction (AEC) community; although, conflicting approaches and methods to combat the issues are present. For example, green building standards are widespread throughout the world; however each one has its own characteristics and consequently its own specific requirements. While all have proven to be effective rating systems and have similar requirements, the distinguishing characteristic that separates them is their treatment of performance and prescriptive metrics. The feature they all severely lack or currently limit is the inclusion of strict …

Managing Moisture - The Key To Healthy Internal Wall Insulation Retrofits Of Solid Walls, Joseph Little, Benat Arregi

Conference papers

This study investigates the appropriateness of internally insulating solid walls to the Passivhaus standard. A number of variables are assessed using numerical hygrothermal simulation (under EN 15026) to check (1) associated risk of mould growth on original substrate and (2) if they result in a greater likelihood of timber decay at built-in joist ends. While air and vapour control layers (AVCLs) perform well regarding mould risk in low absorption walls, the results question their appropriateness where joist ends are built-in: when AVCLs are used, moisture levels at joist ends can potentially rise above critical thresholds, even in low absorption walls. …

Designing Affordable Housing For Adaptability: Principles, Practices, & Application, Micaela R. Danko

Pitzer Senior Theses

While environmental and economic sustainability have been driving factors in the movement towards a more resilient built environment, social sustainability is a factor that has received significantly less attention over the years. Federal support for low-income housing has fallen drastically, and the deficit of available, adequate, affordable homes continues to grow. In this thesis, I explore one way that architects can design affordable housing that is intrinsically sustainable. In the past, subsidized low-income housing has been built as if to provide a short-term solution—as if poverty and lack of affordable housing is a short-term problem. However, I argue that adaptable …

Survey Of Suitable Plants For Cal Poly's Green Wall, Katrina Burritt

Horticulture and Crop Science

Green wall technology is a growing industry in the United States and has been very successful for a several years throughout Europe. The objective of this survey was to study the success of several different species of plants on a vertical wall facing south at Cal Poly’s Horticultural Department Unit. At first the focus was aimed at using California native species, because it was thought that natives would be better acclimated to the exposure in this specific location. It became apparent that plants should not be selected for the wall based just on the fact that they are California natives. …

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 …

A two-day conference on the benefits of creating urbanity in weak-market cities gathers twenty-one international experts in architecture, landscape architecture, and urban design, as well as planning, policy, finance, economics, and real estate development. Participants share strategies for cities whose urban character has devolved radically due to economic, demographic, and physical change - cities that are now considered "formerly urban."

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.

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.

In Transit - Transition Movement Inspires Dramatic Carbon Cuts In House Refurb, Joseph Little

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 …

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. …

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.

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 …
