Life Cycle Assessment Of Building Projects
A. Bhatia, B.E.
This 2-hour course
introduces the concepts of life cycle assessment to the building projects. It
describes the life cycle analysis methodologies with specific illustrations
to the air-conditioning functions of the building elements. This course is designed
to meet the continuing professional development needs of individuals involved
in managing resource development, building design, construction and project
It is suitable for students, managers, engineers, auditors, equipment manufacturers and the designers. It shall also be beneficial for individuals who utilize information from life cycle cost estimates, supervise cost estimates, prepare budgets, manage acquisition programs, evaluate and negotiate contract proposals, or desire grounding in the basic techniques of cost estimating.
This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of the course materials.
At the conclusion of this course, the student will:
and capital offsets are important economic parameters for evaluation of building
projects. The course provides basic fundamentals concepts of life cycle assessment,
as applicable to the buildings. The course provides the generic reading on the
building projects with a special focus on the air-conditioning aspects to the
The the course content is in a PDF file Life Cycle Assessment Of Building Projects. You need to open or download this document to study this course.
The course presents
the basic understanding of the fundamental concepts and terminology used to
compute the life cycle assessment specific to building projects. The procedure
may be greatly simplified by the use of readily available software programs,
but understanding of these concepts remains vital particularly for the individuals
who have not had any previous experience in this area.
Life cycle assessment (LCA) is a decision making process that is applied to large scale building projects for evaluating the appropriate selection. The LCA takes into account all capital costs, recurring operation & maintenance (O&M) expenses, replacement costs, energy, environment and the code issues for the life cycle of equipment.
LCC are summations of cost estimates from inception to disposal for both equipment and projects as determined by an analytical study and estimate of total costs experienced during their life. The objective of LCC analysis is to choose the most cost-effective approach from a series of alternatives so the least long-term cost of ownership is achieved.
The course HVAC made easy - 'Glossary and Acronyms of HVAC systems' is a compilation of most common HVAC terminology and is a recommended reading. The abbreviations and terms that may be unfamiliar to someone exploring HVAC systems for the first time have been carefully selected and presented in alphabetical order.
Cooling Water Systems
HVAC system is a significant proportion of the overall building costs and the cooling water system is one of the major cost elements. The air-conditioning systems on the big infrastructure-building projects generally use cooling towers for heat rejection. A 4-hour study course title "Cooling Water System- Overview of Cooling Towers" presents fundamentals and technical analysis of the various cooling water system options.
The chiller package comprising of refrigerant compressor is a heart of main cooling system. The chiller is a single most expensive item of the air-conditioning system that influences the life cycle economics of the air-conditioning system. The chillers have been discussed exclusively in another course HVAC made easy - 'Selection tips for chiller compressors'. This 2-hour course summarizes briefly the technical merits and demerits of using different compressors.
Once you finish studying the above course content, you need to take a quiz to obtain the PDH credits.
