At PHIA, we want to promote a way of life that is healthy and comfortable, while being friendly to the environment. Construction of buildings influences not only the functionality and design of the built environment, but also our living conditions and climate change. On the other hand, advance information technology has rapidly digitalized our world and increased the importance of connecting all things. We aim to combine Sustainability and Digitalization as a Building Standard for the future. The Passive House Standard is the ideal solution as it is: applicable for all climates, materials, construction methods, designs, technical services and not limited to a single manufacturer. Passive House principles have been fully developed and adapted for tropical climates and has proven to be economical in the long run.

Our concepts for Sustainable cities or buildings should contain a lot of natural greenery, which directly improves the microclimate of public areas and the indoor environment of the buildings. We place a high importance on people and we believe that new building standards can and should be available to everyone, regadless of social backgrounds, nationalities or cultures. Architecture and Design is a selfexpression of the culture and values from where the building originates. Though sometimes impractical, it is necessary to create the identity of the structure and to instill meaning for its existence. Fortunately, current knowledge and technical know-how have provided the opportunity for new buildings to have the best of architecture while complying with performance requirements.

We want to combine Passive House techniques with Digitalization of Buildings, to create ‘Building 4.0’, a derivative concept from Industry 4.0, where Information Technology has revolutionized the Internet of Things. We understand the boundary conditions of tropical buildings and we are looking at ecological, economical and energy efficient ways to design and build them. It will be a building where all technical services are connected, to achieve an optimum level of comfort and performance. The occupants play a secondary role in controlling the building, by merely stating their needs, while the building autonomously adjusts itself to those needs. This is the definition of ‚Passive‘, where the system works in the background We believe that Passive House principles in combination with Digitalization will create tropical Passive House as Building 4.0, the solution for present and future! 5

While modern civilization has brought about tremendous benefits and comforts to mankind, it has also pushed the earth to its limits. As a result, we are now facing global ecological disasters such as climate change, global warming and resource depletion. Energy is the common factor among these problems and buildings contribute to this by accounting for 40% of global energy use. It is imperative that new and existing buildings be constructed in a way that has minimal or zero ecological impact, whilst being cost efficient and sustainable.

Passive House Standard as Part of the Solution The Passive House Standard is an ultra energy efficient standard that will significantly reduce a building‘s carbon footprint. Originally developed in Germany, the Passive House Standard is a unique solution for sustainable buildings because of its ultra low-energy design requirements. The first Passive House was built in 1990, and since then over 20,000 living units have been realized in Central Europe. With Passive Houses having been built in Europe, North and South America, Africa and Asia, it has become an internationally recognized standard for sustainable architecture.

Efficiency at its Best Passive House has energy efficiency at its core but other factors are also important when constructing one:

C omfort Passive Houses are able to provide optimal room temperatures and a consistent supply of fresh air for the building occupants throughout the year. This makes it an attractive option for people who wants to increase their quality of life.

A ffordability Contrary to popular belief, Passive Houses saves money. The investment into higher quality building materials and components is mitigated by the elimination of expensive heating and cooling systems. High energy savings also reduces the building‘s operating cost, decreasing the payback period significantly.

S ustainability Passive Houses use up to 90% less energy than standard buildings. Reduction in energy equates to reduction in greenhouse gas emissions, thus lowering the ecological impact of the building.

Everything about the Passive House aims to solve global environmental problems.

> Lower Ecological Footprint > Work with what nature provides and not against it

Higher Quality



No matter what the outside conditions are, Passive Houses ensure that the indoor environment remain comfortable and clean.

> Optimum air temperature > Dust-free, Pollutant-free, Bacteria-free air > Increase work productivity

V e r s a t i l e C o n st r u c t i o n The Passive House standard is based purely on building performance and quality and therefore it does not specify any particular methods of construction. Whether is it solid construction, wood or composite, architects are free to be creative with their Passive House designs. It is a very versatile concept which is applicable to all building types in all climate regions. 9

3, AIRTIGHTNESS An airtight building envelope will prevent infiltration of warm, humid and polluted air, whilst maintaining the cool indoor temperature


6, DEHUMIDIFICATION Energy Recovery Systems will dehumidify the supply air, reducing latent cooling load and ensuring dry indoor air - comfort and prevention of mold growth

7, EFFICIENT VENTILATION A constant supply of fresh air keeps the indoor environment healthy. Outside air is filtered, pre-cooled before entering the interior

TROPICAL PASSIVE HOUSE What is our Building 4.0

Why to choose Building 4.0

Buildings of the future have to evolve beyond providing comfort and protection for its occupants. Apart from being ‚green‘, technological advancements have now allowed buildings to interact with its occupants and surroundings in a more connected way. The term ‚Building 4.0‘ stands for the fourth building evolution and it is a concept where the principles of Sustainability, Digitalization and Passive House Design are combined to form ideal solution for the future.

Building 4.0 is a higher level of building standard, where performance is not the only requirements. It aims to provide its occupants with a comfortable and healthy lifestyle that is convenient and free of hassles, so that they can focus on productivity and other pursuits. It is a building where all functions and services operate ‘behind-the-scene’, through autonomous control and predictive learning of the occupants’ behavior.

AS BUILDING 4.0 How to achieve Building 4.0 Sustainable Resource

Autonomous Control

The building will utilize available natural resources of its surrounding. In tropical countries, the building must capture solar energy with PV panels and water through rainwater harvesting.


Technical services such as cooling, lighting and ventilation operate in combination with smart sensors and control systems. The users are free from the responsibility to switch devices on/off, or adjust input powers as these will work automatically based on the surrounding environment and need.

Adaptivity The building is able to adapt to different purposes (work or leisure) for different types of occupants (single person or family). This ensure a high level of comfort for every occupant in the building without the replacing or installing additional services.

Connectivity In a single housing or office unit, advanced networking will link sensors and components to each other. The single unit will also be linked to other units or buildings, created a multi-layers system in which information is easily accessible to the users, providing further opportunities for performance optimization and resourcesharing.

Economical Efficiency Passive House design in combination with efficient and optimized technical systems achieves major cost savings through the reduction of energy usage. Without the need for expensive cooling or heating systems, investments and operational costs will be cut down as well. All these will increase the value of the building as a whole

Smart Management Networking between all building services (Security, Energy, Waste, Water, Maintenance, etc) will simplify the management of the building for the users. Resources are only used when it is needed

Architecture must always make an attempt to go beyond functionality. Modern architecture itself has to always redefine its task and provide the right solutions concerning material and design. The design itself should emulate forms and patterns found in nature and exist in harmony with the natural environment. At PHIA, we understand that we are in working in an era of „climate change and energy transformation“, therefore we actively seek revolutionary solutions in the area of sustainable building design. We believe that mankind has progressed in the ‚wrong‘ direction in terms of modern development by causing harm to our natural ecosystem and simply slowing down the process is not enough. Instead the solutions have to be regenerative in nature and bring about positive transformation to the earth and the people. PHIA consists of a strategic partnership between several successful and experienced architects, engineers, professors and consultants. We are highly motivated and possess the necessary qualification and expertise to realize passive house building projects from start to completion.
