The main objective of the TD sessions consists on familiarizing the student with dynamic building thermal simulation. The aim of this course is to sensibilize students of architecture on ÒClimate Responsive DesignÓ (or alternatively named ÒBuilding ClimatologyÓ) through the use of a variety of software. Hence, students of architecture will develop a scientific methodology regarding the definition of accurate simulation protocols regarding a given architectural project. Then, they will learn how to modelize a building in order to contact thermal simulation starting from the building enveloppe to the whole building. A synergy between the output of each software will be established in order to adequately interpret the environmental impact of the architectural design.
The module is designed in 5 modules distributed during the spring semester for architect-engineer students. At the end of the 5th sequence each student has to have produced all the needed pieces for the design of a small single-zone building with a specific function (residential / small office building, etc). The form of the building has to been evolved from session to session adding each time the new levels of the studies from the issues covered in each module (climate, envelope, ventilation, solar gain, etc). At the end of each session each student has to develop an own set of design criteria against which the proposed final building design can be evaluated employing thermal simulation. Students have been given a specific climate to conduct their analysis and integrate the specific climatic parameters to an adequate architectural design. An introduction to the finit element and the control volumes methods will be held during the TD sessions in order to explain how dynamic thermal simulation software conduct all the needed calculations in a short time lapse..
After the accomplishment of the TD sessions the students will be able to
i) Conduct a detailed climate analysis employing the software Climate Consultant
ii) Propose design guidelines for an architectural project employing the software Climate Consultant
iii) Trace in detail the sun motion during a day in every season using the software Climate Consultant
iv) Provide a design of sun controls employing the software Solar-2
v) Conceive an adequate to their architectural design natural ventilation
strategy employing the software Solar-2
vi) Study in detail heat flow through opaque elements and integrate phase change materials within the envelope in order to improve the time lag of their constructions employing the software OPAQUE
vii) Study the overall thermal performance of an architectural project during simulating one year of operation: calculate the balance sheet of heat gain and loss employing the software HEED
viii) Calculate the passive heating and cooling of their project employing the software HEED
ix) Provide and evaluate an optimum final energy conserving design employing the HEED software
During the sessions we will use four computer programs that have been developped by the Architecture Department of the University of California, Los Angeles to aid student learning in each module of the course, and also to support architectural design decision making once they get out into practice:
a) Climate Consultant (that graphically analyzes 8760 hour climate data files).
b) OPAQUE (that evaluates the performance of the opaque envelope of the building)
c) SOLAR-2 (for the design of a window with any combination of sunshades)
d) HEED (Home Energy Efficient Design, for integrated whole-building energy performance)
All these programs are open source and can be downloaded (at no cost) from www.aud.ucla.edu/energy-design-tools.
The TD session will take place in the PC lab of the Department of Architecture.
The students have to submit a report (30 pages A4 format) where they summarize the different simulation protocols that they developed in order to conduct multi-scale thermal simulations. Furthermore, within this report they have to outline the formal evolution of the given architectural project under study according to these simulations.
