ENRG09019 2013 Energy and the Built Environment
On completion of this module the learner will have an advanced understanding of Sustainability and its complexities and impact on the Built Environment including energy directives and future development, they will also have a critical understanding of the relationship between climate change and buildings and the impact this has on energy efficiency and construction. The students will also have an advanced knowledge of energy policy and building energy performance, passive design and service integration. Finally the student will also have an advanced understanding of how the application of renewable technologies to existing buildings affects their performance. As core to this module the student will engage directly with industry through projects or workshops to advance critical discourse in the field of Energy and Built Environment.
On completion of this module the learner will/should be able to;
Have a critical awareness of the impact climate change has on the Built Environment and how this is shaping policy and construction to improve efficiency of both existing and future developments
Have an advanced understanding of the energy performance of buildings the impact of policy and the evalution of national and international energy rating systems and their application, as applied to industry based projects or direct industry engagement.
Prepare a comprehensive assessment of a proposed new or existing building, within its locality in either an urban or rural context which also engages directly with individuals in the field or industry.
Have an advanced understanding of the role of energy in the built environment and have the ability to assess the most suitable design strategies to enhance and surpass current policy requirements whilst choosing building technologies to achieve this for a given site or scheme
Module Assessment Strategies
Major individual project; Learners will be required to carry out an appraisal of a selected existing building and prepare a comprehensive environmental assessment report including its macro/micro urban and rural context, the evaluation must include environmental design strategies and technologies used in the selected case study from industry and the region, up to and including direct engagment with individuals and industry.
This module is divided into a number of Themes:
01 Sustainability (Deriving appropriate criteria for defining sustainability) in the 21st Century:
Defining Sustainability: This Lecture will discuss Sustainability in the context of how it is a much over used and misrepresented term, We are shaping Earth so profoundly that it is evident in geological record (Brand, S. 2010:275) we have as a result become stewards of Earth and its resources, a point also not lost on Intergovernmental Panel on Climate Change (IPCC). Furthermore this lecture will explore sustainability as well as its various indicators. The Lecture will go on to conclude with a Definition derived from current research and debate, showing how it can be blended from a range of sources.
What is Sustainable city and how do we define it?: This Lecture covers the issues around sustainability within our towns and cities asking the pertinent question what makes a city a city in today’s world? its further explores Carolyn Steel's debate framed around the notion of resource depletion; she argues Today, almost every aspect of industrial farming involves the use of oil in some way from running machinery to making fertilisers and pesticides to transport, processing and preservation of produce. Around four barrels of the stuff go into feeding each of us in Britain every year………..We are effectively eating oil. The Lecture concludes discussing urban and rural development and pollution, as well as green /sustainable /cities
02 Climate Change on the Built Environment:
Climate and it effects on Building Design: This Lecture covers Climatic Factors that impact on construction, it further discusses how Buildings are necessary for human comfort they provide shelter from the effects of climate which are know to be extremely variable. It also discusses the Landscape and how one might analyse a Site in a given context. Finally it introduced the student to passive dasign and daylight in buildings.
Effects of water on Building Fabric: This lecture will discuss Moisture in Buildings, Condensation, Rain penetration, Breathability and the impacts weather and interior conditions has on Energy Efficiency, it concludes with an introduction to Insulation in buildings, and Internal Insulation and Retrofit.
Passive House Design: The Aim of these two lecture is to introduce Passive House concept, it will go onto to discuss its history and development then examine the methods, design guidance and specific components necessary to meet this standard. There will be some case studies presented and construction details analysed, In conclusion it will discuss Passive House concept in terms of costs, energy savings and potential problems.
03 Energy Performance of Buildings:
Buildings and Energy: This lecture will focus on the Built environment and how is accounts for almost 50% of our energy consumption and carbon emissions. The energy balance within a building, and how regulations and energy rating procedures, are aimed at measuring of the energy performance of a building, if further discusses how policy frameworks in the EU and Ireland and how they are setting targets to minimise the energy input for heating and cooling on the total energy balance. Finally this Lecture introduces the student to BREEAM (BRE Environmental Assessment Method) The Code for Sustainable Homes, LEED and Green Star.
Evolution of Part L: This lecture looks at the origins of Part L Building regulation and its impact on the built environement linked to national and international policy.
Ventilation in Buildings: This lecture we will explore how activating a buildings natural ventilation cycle will deal with the buildup of moisture, if will also discuss why ventilation is needed, nethods of natural ventilation, Airtightness and infiltration and how if ventilation is utilised correctly it can reduce the energy load on a building.
Building Energy Rating & Proformance Methods: These two lectures will discuss the many methods available internationally for assessing the energy, environmental and sustainability performance of buildings, it argues the need to assess the performance of building because of the effect this may have on it occupants and the wider environment, locally and globally. And Finally in the second lecture it will go onto discuss Post Occupancy Evaluation the potential it has for hightlighting the effectivness of built environement to respond to users needs from an health and well-being to the impact of energy efficeny.
04 Water management and Building Services: This Lecture will focus on sources of water its treatment and use within a building. It will further discuss water effciciency, Supplementing existing water supplies and finally focus on water in the context of greenhouse gas emissions and sustainable development. The Lecture will also explore mechanical services commonly utilised in buildings, identify the types and their application and fianlly it will conclude by showing how we can avoid mechanical ventilation. In the second part of the lecture it will explore Lighting installations it will discuss light, Illuminance level and distribution its laod on energy consumption and impact light has on health of the building occupant, finally it will discuss passive solar strategies and daylight.
