Urban Energy Technical Note No. 10 - Key Strategies for Sustainable Building Designs in the Tropics

This document offers key strategies for sustainable building designs in the tropics, from site selection and building orientation and form to heating, choice of building materials and energy efficiency of appliances.

Urban Energy Technical Note No. 09 - University Curriculum Development

The transition towards clean energy and sustainable use of resource calls upon all stakeholders across different sectors of the society for fundamental changes.

Urban Energy Technical Note No. 08 - Passive Cooling

Passive cooling systems use nonmechanical methods to maintain comfortable indoor temperatures and are a key factor in mitigating the impact of buildings on the environment.

Urban Energy Technical Note No. 07 - Energy and Resource Efficiency Checklist

The best opportunities for energy efficiency in buildings are at the design stage. Designing for energy efficiency reduces the overall demand for resources to generate energy.

Urban Energy Technical Note No. 06 - Renewable Energy Projects

Renewable Energy Sources (RES) are playing an increasingly important role in the generation of electricity (RES-E) as well as in the provision of other forms of end-use energy. About 50% of the total new capacity of electricity generation installed in 2010 came from RES (IEA 2011).

Urban Energy Technical Note No. 05 - Energy and Cost Savings - EE Appliances

Did you know that there is a worldwide trend towards energy efficient appliances and building materials? And did you know that growing awareness and appreciation of the environment is set to increase the demand for green buildings.

Urban Energy Technical Note No. 04 - Natural Ventilation

Thermal comfort in the built environment is affected by air temperature and air movement. Ventilation, which is simply the removal of stale indoor air from a building and its replacement with fresh outside air, has a great impact on thermal comfort.

Urban Energy Technical Note No. 03 - Sun Shading

The most significant factor affecting the built environment in the East Africa region is solar energy, which impacts on it throughout the year. The shapes of buildings and spaces have a great effect on indoor temperatures.

Urban Energy Technical Note No. 02 - Climate and Architecture

The way buildings are planned and designed today has a direct implication on the energy consumption, hence they have a strong potential to negatively or positively impact two important elements of everyday life: our environment and energy bills.

Urban Energy Technical Note No. 01 - Guidelines for Green Building Design

Over 70% of the world energy generation is consumed in human settlements, resulting in an emission of more than two thirds of CO2 that contributes to climate change.
