Technological and Construction Material-Based Measures Against Extreme Heat

Gray measures, one category under climate adaptive options for the built environment, make use of technology and construction materials to avoid the increase of heat hazard. Some examples of cooling through enhanced design are the use of insulation, solar blinds on exposed buildings, the creation of natural ventilation and shade, the selection of construction materials and reflective coatings, and modifying the form and layout of buildings [2].
Climate Adaptation Effectiveness

A pilot project in Sorsogon City made use of MIRACOOL, a high reflective heat insulating coating that reduces surface temperature of buildings. The application of the said coating on the roofs of a school caused the temperature to drop from 50 to 32 degrees. It was also observed that the room felt cooler. [3]

Evaluations

Economic / Financial Effectiveness
Mid

The cost of retrofitting is significantly lower compared to new construction minimizing the need for materials to be extracted, manufactured, and constructed. For the urban poor, cool roofs is the viable option compared to insulation [1].

Technical Feasibility
Mid

Design and engineering expertise is required for this solution.

Social Acceptability
No Evidence

Environmental Impact
Low (-)

The use of air conditioning is included under this solution which can contribute greenhouse gas emissions and may lead to enhanced urban heat island effect [2].

Mitigation co-benefit

Natural cooling and ventilation can reduce energy use.
