2. ABSTRACT
A study conducted to assess heat gain concerns and overall comfort levels in an institutional
facility housing police officers and inmates. Participants include officers from the Philippine
National Police (PNP)/Bureau of Jail Management and Penology (BJMP), as well as Persons
Deprived of Liberty (PDL). Sampling methods ensure representation while maintaining security
protocols.
Data collection involves a mixed-methods approach, utilizing structured questionnaires and
interviews to gather quantitative and qualitative insights. Findings suggest a need for improved
building design and materials to enhance comfort and energy efficiency while prioritizing
security. Implementing such strategies can create a healthier environment for both inmates and
staff.

DESIGN ISSUES
DESIGN PROPOSAL

15. BRISE SOLEIL OR SUN BREAKER
BUILDING MATERIALS AND SYSTEM
Green materials help reduce the negative environmental impact when it is used at the building and contribute to
healthier, more energy-efficient, and cost-effective spaces for occupants.
LANDSCAPING
Brise-soleil can add a unique aesthetic touch to a building's facade. Horizontal brise-soleil can be placed above
windows to block direct sunlight while allowing diffused light to enter.

FIRE SAFETYSAFETY FEATURES
Eco-friendly paints limit the exposure of people to dangerous materials, and their living environments become
safer. Furthermore, employing low-VOC paints benefits both the external environment and internal air quality.

PAINT

17. Building metal roof surfaces shall either be colored white or have a minimum SRI of 70.
(The Philippine Green Building code, 2015)
ROOF COLOR AND INSULATION
Good insulation helps maintain consistent temperatures throughout the facility. This creates a more comfortable
environment for both inmates and staff, regardless of the season. Extreme temperatures can be dangerous and
contribute to tensions within a correctional setting.
This is to recommend the use of light colored paint
as this is a tool for creating comfort and enhancing
natural light and improve dark areas.

19. AIR CONDITIONING UNITS
MECHANICAL SYSTEM
Building offices are equipped with air conditioning units but some offices didn’t maintain the cooling inside, as this is one of
the problems encountered by the affected users.
NEED MAINTENANCE AIR CONDITIONING
CAPACITY
EXCESSIVE HEAT
Incompatible air conditioner units in large rooms and the high number of occupants inside can result in high energy use and
discomfort for the user.

20. EXHAUST FAN
It can be a helpful tool for reducing heat buildup inside correctional facilities to use Exhaust fan, especially in their cell room.
IMPROVED VENTILATION REDUCED HEAT STRESS CONTROL ODOR
By implementing a combination of these strategies, correctional facilities can create a more comfortable and healthy environment for
inmates and staff while maintaining security considerations.
WIND CATCHER
Windcatchers might not be as aesthetically pleasing but still
provide some natural ventilation and passive cooling benefits to
correctional facilities. This can improve comfort conditions for
inmates and staff, especially in dry seasons.

21. SOLAR PANEL
ELECTRICAL SYSTEM
Solar panels can significantly lower the reliance on the
grid, leading to substantial cost savings in the long run.
DAYLIGHT PROVISION
Daylight provision in correctional facilities is an emerging area of focus
that offers potential benefits for both inmates and staff. It improved
physical and Mental Health, reduced stress, enhanced safety and security.
SENSOR FOR LIGHTING CONTROL
This sensor is ideal to use at restrooms and hallways for energy saving and
cost-effectiveness. Investment in occupancy sensors is typically recouped
within a reasonable timeframe due to the substantial energy savings.
Additionally, reduced lighting usage translates to longer bulb lifespan,
leading to lower maintenance costs.

22. WATER SUPPLY
The water supply in Metro Manila can be a bit of a complex issue.There are some areas that have scheduled water interruptions
affecting the residents and users around the region as this is one of the concerns of the inmates and staff in the building.
SCHEDULED MAINTENANCE
WATER SHORTAGE
As part of the solution on this problem especially users located at the
second floor to Fourth floor,
1.Additional water tank
2.Gravity fed water pressure
3.Rainwater Harvesting
4.Reusing greywater from Laundry
For public comfort room,
1.Sensor Activated Faucet
2.Manual Flush for toilets

23. WASTE MANAGEMENT
Educate inmates and staff to familiarize in proper sorting procedures for recyclables are needed. This is to
recommend clear labeled recycle bins and ensure the collection of waste and recyclables from the haulers.
