Abstract
This article discusses the design of a very low energy
residential building, with regard to the climate ofNew
Borg El Arab City (NBC). However, since the cost of a
very energy efficient building can be high, twoinvestment
scenarios, low (LIS) and high (HIS) investments, have
been considered. In the first case, thedesign includes
exclusively low cost solutions, while in the second case
technologies commonly asso-ciated with Net zero houses
are included. Both cases have been compared to a
reference case, calledbusiness as usual (BaU), which
refers to the minimum requirements of the Egyptian energy
code. Thefinal energy consumption of LIS has been
estimated around 15 kWh/m2, which is half of the final
energyconsumption of the BaU building. Particularly
interesting are the results of HIS: the final energy
con-sumption varies from 5 kWh/m2to 1.48 kWh/m2and to
0.69 kWh/m2as the PV size increases. Very lowenergy and
net zero energy buildings have been designed in line with
the local context, using envelopesolutions to lower their
energy needs and renewable systems to achieve a near zero
or a negative finalenergy balance.
