Sustainable House Design: Integrating Solar Energy and BREEAM Analysis

This presentation provides an overview of sustainable house design, emphasizing the integration of solar energy and the importance of sustainability principles within the building industry. It highlights the use of solar energy for heating and cooling through solar panels and discusses key design principles such as passive solar design, window location, and building orientation. The presentation also covers building suncast shadow studies across different seasons, daylighting analysis, and photovoltaic potential, considering factors like land topography, location, and atmospheric effects. Furthermore, it introduces the concept of Autodesk Revit energy models and their role in assessing heating and cooling loads. Finally, the presentation touches upon the BREEAM assessment, focusing on aspects like management, health and wellbeing, energy, transport, water, materials, waste, land use and ecology, pollution, and innovation, concluding with the interdependence of solar energy and sustainability.

Title:
Sustainable House Design

Introduction
Sustainability
This is a wider concept in building industry
especially housing
It aims at large scale production with little resource
management
Characteristic of suitable design include being
energy as well as energy efficient.
Building industry is already using sustainability to
reduce the expenses in the maintenance and even
building costs.

Solar Study
Buildings account for more percentage of
the energy consumed in most countries
The solar energy consumed in buildings is
tapped by the use of the solar panels
This energy is used in heating as well as
cooling.
Design principles are applied in the use of
the technologies in buildings

Design Principles
 Renewable energy are meant to save money
 Approaches of the design only improves on
the efficiency but not costs
 Com only exploited design principles for
solar in building include: Passive solar
design, window location and building
orientation
 Additional low cost passive design
characteristics.

Building suncast shadow
study (spring, summer,
autumn, winter)Path of the sun in relation to season will vary
Design must factor it this variation for
sustainability
This is because the position of the sun
affects the level of comfort by the users of
the building

Suncast continues….Suncast continues….
 Measurement can be achieved by the use
of the following components:
Sunscale: Gives intuitive representation of
the path of the sun
Sollimus: Utilizes the Google maps
Sunchart

Building Internal sun
penetration
 Daylighting analysis:
The design of the building should allow for
maximum utilization of natural day light
Intensity and glaring effect to be controlled by
proper interior architecture
Analysis of solar radiation:
Solar orientation perimeter to be considered crucial.
Windows and doors to be utilized as major
openings

Photovoltaic potential

This will be affected by the following
factors:
Land topography: The angle of the
reflection as well as the nature of the
ground being hit by the rays
Location: Polar Regions are likely to be
less effective as compared to the tropical
land
Atmospheric effects: Cloud cover as well
as dust particles acts as barriers.

Autodesk Revit energy model
 Model of energy is basically an abstraction
of the overall form of the building
It utilizes several aspects including;
Spaces which constitute discrete volume
Surfaces: considered to be the paths of
heat travel
Zones: Spaces grouping useful in the
establishment of some commonality

Heating and cooling loads
Results from the thermal heater, cooling fans
among other appliances
Sustainability of these processes will require
constant supply of energy
Their utilization will be expected to be more
pronounced in area with extreme
temperatures.
Efficiency will depend on the effectives of the
solar panels in places.

BREEAM Assessment Stanley
road development
 In management: Flow of work and coordination in
bid to save on resources
 Health wellbeing: How suitability contributes to
wellbeing of the
 Energy: Possible renewable energy sources with
the potential highlights
 Transport: Sustainable modes of transport e.g.
electric trains
 Water: Cheapest and energy saving mechanisms in
water recycling

Beam…Beam…
 Materials: Guidance of the most effective materials
to be used in support of the sustainable growth
 Waste Sustainable waste managements
 Land use and ecology: Ecology and land as the
reservoir of energy
 Pollution: a consequence of the energy production
process
 Innovation: Creative ways of tapping renewable
energy for sustainability

ConclusionsConclusions
There is very strong interdependence of
solar energy and sustainability either direct
or indirect.
Solar radiation intensity and duration are
the key parameters to be considered in
similar evaluation.
