Arch are tools that are used in order
to few replies on how a building's
energy use becomes based on the choices that are done concerning the actual building
and its HVAC systems. The tools are deliberately tailored in order to function
practical situations during construction - and the administrative process.
Arch are the tool for architects/construction consultants
and clients/real-estate owners. BV2
Arch is formulated in order to be used in the
early state of a building's process before technical systems been chosen.
Focus lies here on the building's formulation and which effects the building's
geometric mould, direction, façade structure, choices of window type and façade
design and solar shadings may for effect on the building 's heat surplus
respective heat deficits.
is the tool that takes at after BV2
Files as been created in BV2
Arch can of course be read in in BV2
and is processed furthermore. Here, we speak then about the system stage and the project small
stage then the building e.g. provided with technical systems in order to heat, chill and
to ventilate the building. In these stages works HVAC consults and project era spirit
HVAC entrepreneurs with choosing and dimension era these systems. BV2
can then help
them to choose technical systems that function along with the building so that the
energy use to be minimized concurrentlely as climate requirements and profitability
is maintained. For architects/construction consultants that want to further to
deepen themself in questions that concern buildings' energy use, BV2
is of course
In an existing building ithere arer most often limited possibilities to influence
the building's geometric mould, direction, basis structure, and façade design.
Here is the therefore BV2
as is the natural choice. Although it of course is
all possibilities to influence the building's fundamental appearance also in
so is the most often questions about renovating or replacement of windows,
addition isolation, solar shadings, activity changed and completion or change
of technical systems/control (heat, chill ventilation) that is current to
analyze and few one good decision-making bases on.
These questions employ mainly real-estate owners, construction consultants,
HVAC consults, HVAC entrepreneurs, energy consults and independent experts,
what will work with energy declaration of buildings. All these have big good
then an one existing building energy will be rendered more effective.
With the user friendly formulation and extensive graphical result presentation,
is suitably in education contexts. That with a simple but nevertheless reliable
tools that BV2
can laborites and examine how the energy use
(heat, chill and electrical) influenced by various formulations and measures in
building with its HVAC equipments. Students get a better knowledge and understanding
about buildings' energy use. It is of course these students that will hollow the
energy use in the settlement with 20 - 50% the nearest 20 - the 50 years!
Already today BV2 are used in the education on university level on e.g..
Chalmers Göteborg, KTH Stockholm, Karlstad universities,
Örebro universities and the State's agriculture university.
