39Aim

• The aim of this guidebook is to develop a basic framework of a

design guideline to deliver the most appropriate and cost-

effective solutions for NZEB in Mediterranean climates.

• This guidebook (Part 1) represents specific conditions of

Mediterranean climate, aspects related to theoretical background

and building envelope design.

• Additionally, case studies and a database are described.

• Residential buildings are mainly considered in this guide book.


40Basics

1. Climate is the main factor affecting a building and its HVAC

system design. Design strategies should be different for cold

climates and hot climates.

2. In the Mediterranean region the climate is different and new

strategies need developing.

3. In hot climate conditions, cooling is the principal energy

consuming process.


41Basics

4) Utilizing natural forces has considerable benefits in

decreasing cooling loads.

5) Case studies may guide further actions by demonstrating

suitable strategies that may be applied.

6) Heat losses and/or gains through the envelope are the main

elements of the total load for residential buildings.

7) Due to the large daily swing in climatic variables in the

Mediterranean region, building envelope dynamic responses are

particularly important.


42Building Envelope Solutions and Technologies

• In an case study for a residential building in Mediterranean

climate, cooling energy demand is approximately 6 times larger

than heating.

• The annual cooling energy demand is higher for higher

insulation thickness.

• Increasing thermal insulation thickness is not a good strategy to

reduce the cooling energy demand in the Mediterranean

climate.


43

Transparent Building Envelope

• In the Mediterranean region, to reduce cooling energy

costs it is necessary to invest in appropriate windows.


44

Window Frames

• Window frames play an important role in reducing the

window heat loads.


45Shading

• Shading strategies are particularly important in the

Mediterranean climate.


46

The solutions for opaque components

• Living wall

• Green roof and cool roof

• Radiant barriers

• Ventilated roof


Fire Safety in Buildings - Smoke Management Guidelines

Thermal Mass of Opaque Components

Thick stone walls in a hot-dry climate zone perform better than

the insulated walls.

48

Phase Change Materials

• Phase Changing Materials (PCM) can also be used for

providing thermal storage in the contemporary design of

buildings.

NZEB Design Strategies for Residential Buildings in Mediterranean Regions Design Guideline Part 1


Evaporative cooling of the envelope

• Evaporatively cooled surfaces can be applied with different

building envelope components at the outer skin of the

buildings

Natural Ventilation

• Ventilation may help to cool buildings passively.

• the climate is very important to passively cool the space by

natural ventilation


Cost effectiveness – optimality

• Based on the calculations of primary energy use and total costs

associated with the different packages/variants of measures assessed

for the defined Reference Building, the cost-optimal graphs can be

drawn


Appendix – A: Building energy evaluation tools

• In order to properly develop building energy design related

to NZEBs, a suitable building energy performance simulation

tool is necessary.


Appendix – B: Case studies


From the existing NZEB examples available in Mediterranean

zones, a brief survey of the main case studies, that included

their key energy features, is provided in Table B1.


Appendix – C: A harmonized database to share NZEBs good

practice

• A current REHVA task force and, at the Italian level, an AiCARR

team aim to design a guide for NZEBs at a European level based

on real national experiences, creating a support.
