Sunlight and solar radiation, effect of size and position of lighting aperture, effect of pre-set structures on lighting, choice of surface colours, risk of glare, sound insulation, calculation of sound insulation, sound propagation in building interiors, importance of absorptive and reflective properties of building structures, noise reduction by structural design, sound propagation from building to exterior, necessary properties of designed screens.

Requirements:

Submission of the submitted exercises and successful completion of the exam.

Syllabus of lectures:

1. Energy performance of buildings (calculation principle)

2. Energy performance of buildings (Decree 264/2020 Coll. and energy certificate)

3. Thermal transmittance of windows and curtain walls (calculation principle and specific problems for different types of windows and doors, methods for assessing thermal transmittance of CW, thermal transmittance of skylights)

4. Linear and point thermal transmittance (basic and special cases of calculation of transmittance (contact with soil, three acting environments, etc.))

5. Non-stationary heat transfer and thermal stability of the room (temperature decay, phase shift, thermal stability in winter, thermal stability in summer)

6. Historic unheated buildings (practical examples, risks and recommendations for renovation of both structures and buildings as a whole)

8. Sunlight and solar radiation, influencing the duration of sunlight through orientation to cardinal points, size of lighting aperture and external shading screens.

9. Amount of daylight, effect of size and position of lighting aperture on the amount and distribution of daylight in a room. The effect of pre-set structures on the quantity and quality of lighting.

10. Choice of surface colours of building structures, relationship to light reflectance. Assessment of the likelihood of glare risk.

11. Sound insulation or air and noise tightness. Parameters of materials, calculation determination. Importance of corrections for the effect of secondary sound propagation paths.

12. Sound propagation in building interiors, importance of absorptive and reflective properties of building structures. Opportunities for noise reduction through proper structural design.

13. Sound propagation from the building to the outside, necessary properties of designed screens.

Syllabus of tutorials:

2. Energy performance of the building (calculation of delivered and primary energy, consideration of photovoltaic system, creation of energy certificate)

3. Consultation (independent work of students in the PC classroom)

4. Consultation (independent work of students in PC classroom)

5. Risk of overheating in summer (calculation of room temperature according to EN ISO 52016-1, analysis of the effect of different shading devices)

6. Consultation (independent work by students in the PC classroom)

7. Assessment of the solar gain in different shading situations, consideration of the influence of pre-set structures and orientation to the cardinal points.

8. Assessment of daylighting in the specific space, taking into account the effect of the size and position of the lighting aperture.

9. An assessment of the likelihood of the risk of potential glare in a given classroom depending on the position of the glare source and the observer.

10. Consultation

11. Calculation of the frequency-dependent partitioning structure opacity, determination of the weighted and unweighted structure opacity.

12. Calculation of room noise as a function of source noise and room parameters, calculation of outdoor noise as a function of envelope parameters and position of illuminating opening.
