DESIGN CONCERNING ENERGY, AIR MOVEMENTS AND MOISTURE IN NEW BUILDINGSVBFN10
Credits: 7,5. Grading scale: TH. Cycle: A (Second Cycle). Main field: Technology. Language of instruction: The course will be given in Swedish. VBFN10 overlaps following cours/es: VBF050. Optional for: V4bf, V4hb. Course coordinator: Lars-Erik Harderup, lars-erik.harderup@byggtek.lth.se and Birgitta Nordquist, birgitta.nordquist@hvac.lth.se, Building Physics. Recommended prerequisits: VBFF01 Energefficiency and indoor environment, VBFN05 Energy, Air Movements and Moisture at Rebuilding and Administration. The course might be cancelled if the number of applicants is less than 15. Assessment: Written examination with a theoretical part and a calculation part. To pass the course the students also must fulfil and pass the project exercise, do laboratory work and computer exercises. A well accomplished project exercise can raise the final grade. Parts: 2.

Aim
To give the student a basic capability to evaluate and choose building technology and building services in a constructive and critical manner to fulfil the functional demands when new buildings are designed.

Ge teknologerna kunskap att skapa hus som uppfyller krav och önskemål

To give the student knowledge to create buildings which fulfil demands from society and clients concerning energy requirements, moisture safety, comfort and healthy indoor environment.

Knowledge and understanding
For a passing grade the student must

be able to analyse the functioning demands for different kinds of buildings and activities on basis of human health, comfort, needs and building physics.

be able to use analytic and numerical calculation methods when designing building components and buildings to work as well as separate units as a system.

from a holistic point of view be able to design and construct a sustainable building composed of interacting components of different building techniques, building materials, building services, automatic control and the user.

Skills and abilities
For a passing grade the student must

be able to apply calculation methods, simple as well as advanced, concerning moisture safety, thermal bridges, power and energy requirement for heating and cooling, energy absorbing ability, flow control and distribution in pipes and ducts, active heat capacity and how this is influenced by different boundary conditions, convection and heat- and moisture balances.

be able to orally and in written describe, discuss and evaluate different technical solutions.

choose and handle known computer programs to solve partial problems and know the programs range of application and restrictions and how to interpret and present results.

Contents
Different kinds of heat transfer and how it affects humans.

Theory for interchange of heat including thermal calculations, flow arrangements and temperature efficiency.

Heating systems including pressure and flow distribution and hydronics.

Manual and numerical moisture calculations including moisture criteria, critical moisture state, impact of moisture on energy consumption, moisture transport, moisture balance, surface condensation, moisture convection and moisture diffusion.

Analytic models for manual calculation concerning power, energy requirement and temperature distribution

Energy balance calculation with computer programs including influence from advanced thermal bridges.

Component design and dimension for actual solutions.

Functional features and design of air conditioning systems.
