Course Brief
In order to understand the course content it is vital to know its aims and objectives properly, let’s
go through its aims and objectives first.
Course Objectives
1. To introduce the concept of controlling the thermal and luminous environment in the
buildings.
2. To revive the passive heating and cooling systems to minimize energy utilities.
3. To utilize maximum daylighting and design efficient artificial lighting.
Details of the Course
Unit no. 1 introduces different phases of architectural development and response towards
energy-efficient solutions for building design.
Unit no. 2 explicates understanding the concepts related to heat and temperature and clarifies
the process of bodily heat transfer with reference to environmental conditions.
Unit no. 3 describes the effect of climate on the thermal environment and the design of buildings
in relevance to climatic data.
Unit no. 4 elucidates the passive approaches for building design and helps to develop an intuitive
understanding of how heating and lighting affect people and building design.
Unit no. 5 describes the characteristics of passive cooling and understands its direct effect on the
building envelope.
Unit no. 6 helps to understand the need to supplement passive strategies with mechanical heating
and air-conditioning systems.
Unit no. 7 deals with construction techniques and components that are applicable to energy-
efficient construction in general and passively heated and cooled buildings in particular.
3
Unit no. 8 focuses on different daylighting sources that directly or indirectly illuminate the
buildings.
Unit no. 9 discusses different electric light sources, their types, standardized distribution and
fundamental approaches for calculating illuminance due to electric lighting.
This course will, therefore, inculcate the principles of passive systems and mechanical systems
and their relationship with the design of both large and small scale buildings.
Assignments
The course includes two assignments, which are compulsory for successful completion of the
whole course. Each assignment is of 100 marks and out of these students obtaining 50 marks will
be declared passed.
Assignments no. 1 and 2 are theory based assignments and must besubmitted through the online
Aaghi LMS portal before the due date. The schedule for submitting the assignment will be
provided accordingly. The tutor will upload the assignment marks online on the Aaghi portal as
well.
Final Examination
At the end of the semester there will be a final examination, all the students will be expected to
take this examination in the examination halls especially established for this purpose. For any
queries, you can write to the courseprogram coordinator. Suggestions for improvement will also
be welcomed.
We wish you all the best.
