The built environment is constantly changing its approach to
the way it is formed over time due to many different reasons such as improved
technology, nature conservation, aesthetic appeal, etc. Due to recent
environmental concerns such as global warming and carbon footprints everyone is
trying to help play a role in conserving our planet. The built environment
plays a major part in damaging the earth. Countries all around are looking for
ways to save energy and use alternate methods of producing energy such as solar
power and conserving energy. Belgium has taken this a step further by changing
national building regulations, our country along with many others are now
following in their footsteps.
Changes to the National Building Regulations are as follows:
Amendments to section A:
A7 (layout drawings)
(M) In the event of a water heating system installation, the
location and capacity of the water heating system must be provided.
(N) Where provided, details of insulation are required to
satisfy the energy requirements of section XA.
A19 (1) (Competent Persons)
(C) The requirements of section XA are satisfied by a
competent person in accordance with SANS 10400 XA.
A19 (12)
(C) Where regulation XA is by a competent person in
accordance with the requirements of SANS 10400 Part XA, the competent person
who is responsible for such determination shall on the completion of
construction and commissioning of the
building submit to the local authority a fully completed form 4 as contained in
SANS 10400–A.
Additional Section X:
A1 (Energy Usage in Buildings)
Buildings being occupies shall be designed and constructed
so that buildings:
(A)
Are capable of using energy efficiently while
still fulfilling its requirements
(B)
Have features and services which facilitate the
efficient use of energy
A2
50 % of hot water heating must be provided by means other
than electricity, e.g. solar power.
Although the changes will help on conserving energy there
are changes that also take place that limits and architects ability to freely
design. Such as windows are not allowed to exceed 15% of a rooms floor area,
although there are loop holes such as using thermal glass in order to exceed
the 15% it will be extremely costly to the client, and also architects are held
fully responsible if the new additions and alterations are not met.
