The
design of energy efficient buildings is now seen as highly desirable by most
planning authorities. Vipac, a certified assessor of building energy efficiency,
performs thermal comfort and energy studies as well as condensation
studies, using both physical and computational analysis
techniques.
Testing facilities for physical modelling of internal building climates
include:
Boundary Layer Wind Tunnel - to test scale models of proposed buildings
and determine pressure contours on external surfaces. By combining this
information with the local statistical wind climate, the yearly or monthly
potential for natural ventilation in terms of the number of air changes per
hour or open space air velocity can be assessed as well as the optimal
location of air inlets and exhausts.
Solar Simulator, Environmental Chamber, Air Distribution Laboratory and UV
Spectrophotometer - for determining heat and light transmission through a
facade; full scale sample testing to determine air and water leakage, as
well as transmission, reflection and absorption characteristics of sample
materials; laboratory modelling of air conditioning devices, diffusers &
jets and of air dispersion in spaces.
Results of physical models can be trialed and extended through computational
modelling, involving:
Computational Fluid Dynamics (CFD) software, such as AirPLAN and NISA - to
ascertain the natural ventilation potential and building thermodynamics, as
well as to predict, evaluate and optimise the performance of proposed
climate control systems, reducing the annual air conditioning expenditure;
Vipac's heat load evaluation software INSOL for building energy
consumption analysis - to determine the solar heat gain of a building with
consideration to any nearby shielding buildings as well as canopies, sun
shades, glazing configurations and window geometry (ie double-glazed
systems).
On site testing complements Vipac's range of services with the usage of
advanced instrumentation and a multitude of experience in all facets of HVAC.
