Solutions against heat Planning solution In the past, our ancestors had a saying: “Get a gentle wife to make a house facing south”. It is a very natural and simple way of planning to avoid the direction that the sun rises in the east and sets in the west. The south direction is the direction to catch the cool wind, avoiding the radiation of the sun. Of course it is a folk house in the village-rural structure. Modern urban areas depend on many other factors, so it is not possible to completely choose the direction for the project. This is not to say that the direction is dependent. Where possible, the orientation of the building should be optimized. The Vietnamese standard on heat protection for houses clearly states: “For houses, try to arrange so that the west-east side of the house has the smallest surface area to limit solar radiation”. As with clusters of works or complexes of works, it is necessary to design a reasonable total ground, giving priority to good orientation for mainstream works, works with higher heat resistance requirements such as living and working places. Environmental and ecological solutions This solution is associated with the planning solution. This is also a solution that our ancestors have applied very thoroughly in traditional architecture. Trees, water surface are always indispensable elements, accompanying the architecture. Trees create shade, prevent and cover architectural surfaces from solar radiation. The water surface (pond, lake, aquarium …) and green trees regulate the climate, making the environment cooler and cleaner. Under conditions of unsaturated air humidity, the water surface always has the phenomenon of evaporation. Water evaporation is an endothermic process, so it causes the ambient temperature to drop. Trees and water surface are attached to natural land; All have low emissivity, which are effective factors for overall heat resistance, with a large range of influence. Currently, in many urban areas, the ratio of trees, water surface to construction works is at an alarming rate, plus other areas are concretized at a high level (yard, summer, parking lot). …). The surfaces of these materials have high emissivity, causing the air environment to heat up significantly. Architectural solutions This is considered the broadest and most flexible solution. The architectural solution is the combination of the ground and the building block, the design of a reasonable cover structure to limit the surface exposed to the sun – avoid radiation, or reduce the heat conduction in the material, enhance thermal convection. The basic architectural solutions are as follows: Reasonable ground layout, prioritizing main spaces to avoid contact with sun-catching surfaces; push the extra spaces such as stairs, storage, toilet to that side. Create setbacks, negative spaces such as halls, loggias, technical slots, etc. to avoid solar radiation entering the main space surface. Use side shading structures installed outside the enclosure (walls) to reduce radiation and heat conduction. In traditional folk architecture, many places have a bamboo mat on the veranda. This element has been applied a lot in modern architecture with different forms and different materials. Facade complex with “rigid structures” to block the sun; attached to the bearing structure and cover. Usually it is an umbrella, vertical and horizontal sunshades. In the 70-80s, this type of architecture was very developed – especially in the category of administrative and office buildings. Those designs are carefully studied in terms of architectural physics according to the climate and solar chart of each locality. Build thick walls, box walls (hollow), use insulation materials (hollow bricks, insulation panels, 3D panels, aerated aggregate concrete…) for the covering structure. The door design is reasonable in terms of location and materials. These solutions are all based on the principle of reducing radiation and conduction of heat from the outside. Use heat-resistant materials for roofs such as woven panels, brick holes, corrugated iron roofs (for flat and concrete roofs), use heat-insulated false ceilings (for sloping, tiled roofs). This solution must pay special attention to the problem of ventilation for the air mass between the two roof layers. Reduce the emissivity of the building surface with plants, such as growing vines on the wall, garden design – water surface on the roof. This is a pretty good aesthetic solution, but there are certain changes over time. Organize the premises, design the location and structure the door reasonably; design courtyard, skylight to enhance air convection. The goal is for the hot air to escape up and out, making room for the lower heat mass. Technical solution Air conditioners (Air conditioners): Considered modern, and easy to deploy applications. However, air conditioners also reveal certain disadvantages. First of all, this solution consumes significant energy resources, and affects the environment. According to the principle of thermal balance, to reduce the temperature in the room, it increases the outside temperature by the same amount of heat. Besides, air conditioners are difficult to meet for open spaces, too large spaces. Ventilation: In addition to natural convection, forced ventilation is considered an effective solution to combat heat when natural convection is not effective. Properly designed ventilation systems will contribute to heat resistance, and should be taken advantage of – combined with architectural solutions such as skylights. Spraying water, misting: Misting systems have recently been deployed to many applications, in public spaces such as restaurants, and even houses. Spraying water and mist creates the phenomenon of evaporating water and collecting heat, while enhancing air convection. In addition, the pressure of water spray, mist creates cool air movement (will be discussed in the next section). In addition, homeowners can also use specialized heat-resistant paint for the surface of the building, which is also an effective anti-heat solution.

These are two duplex villas in a project area, built on two floors with two separate stair systems. Lakeside location with a very nice view behind the house. When working with the architect, the owner requested to merge the two villas into one with two master rooms but only one system of stairs and elevators, convenient for traffic of all spaces in the house. Homeowners also share that they like bold, strong and cozy tones. Dining room. Kitchen. When surveying the status quo, the architect realized the value of the view from the back of the house to the lake and proposed a solution to arrange two master spaces on two floors behind the house so that the owners can enjoy the beautiful view, at the same time. Time from each room can access the ladder system in the best way. The front space will arrange additional spaces. Bedroom 1. Home office area in bedroom 1. Bath and toilet block in bedroom 1. Walk in closet of bedroom 1. Regarding the interior, also based on the color preferences of the owner, the architect recommends using dark brown and black tones as the main color, combined with gold and bordaux red accents to create warmth. pressure, luxury. Gradient and rust effect paint materials add lively options for family members of different ages. The wood is not painted with PU but uses an oil-infused paint, making the wood appear to be stained with time naturally. Looks more sentimental but still protects the material well. Furniture is custom built and selected from well known brands. Different views of the master bedroom. Walk in closet and toilet block of master bedroom. Thus, in this project of renovating and combining two villas into one, based only on the needs of the owner and with sufficient intervention, the architect brought about appropriate changes. A luxurious, comfortable and cozy new space has been formed. Design: Architect Ngo Ky Chu, Architect Le Tan Phong, TD Solutions

POM House is a small house located on a hillside in Son La province. Like the hill villages of Vietnam over the past decade, the economic development has led to the construction works, making the city more and more cramped. The hill is now a cake with many pieces cut and leveled for a “more convenient” city. When designing the house, the group of architects aims to develop urban and its impact on nature. So half of the land area is for construction and the rest is for natural elements. The eaves are built around the yard as a solid limit to protect the “land” from the impact of construction works. The courtyard is inspired by the patio of the traditional house for midday shade. The living space in the house is arranged quite simply, including a large common space, where all activities take place and is a space for family members to connect. The two side spaces of the house are designed to be smaller as private spaces for rest. Each space is connected to a shared garden but has its own vision for each space. The V-shaped roofs with the lowest point in the middle divide the house into residential and auxiliary spaces. The roof is designed to open to the outside and is carefully calculated to cleverly welcome natural light into the house in the late afternoon when the light intensity has decreased.

Location The bathroom near the bedroom and the main traffic path is usually the bathroom shared by the whole family. More advanced is the bathroom designed in the bedroom. This design is often found in the master bedroom or room for the elderly. The bathroom and hygiene have gradually been more interested in design and decoration by the owner. (Illustration) In today’s modern house, the bathroom is also designed in combination with the dressing room to increase the convenience of use, and at the same time “free” the huge wardrobe in the bedroom. Make use of open space The bathroom is a relaxing place, so if possible, design the bathroom with the side exposed to the outside space. Bathroom windows are wider and facing open spaces such as gardens, courtyards, skylights … and to ensure privacy, use blinds, blinds, or blurred glass with decorative stickers. mind. Should make the most of open space for the bathroom. (Illustration) In case the bathroom is located in a private bedroom, to create a feeling of open space for the bathroom, some homeowners use the bathroom door with transparent glass. Functional subdivision Bathroom is divided into two separate zones, that is, the dry area and the wet area. The dry area is where the lavabo – washbasin and toilet are located. And the wet area is the bathing place. The dry and wet areas are usually separated by a glass wall or nylon curtain. The bath tub has been gradually replaced by cabins, either standing or standing baths, either ready-to-buy or custom-designed. Colors and materials Natural colors and materials are now very popular in bathroom design and decoration. To avoid the boredom of conventional paving bricks, designers tend to use granite, marble, natural sawn stone, wood, gravel… more. Mosaic tiles are used to decorate walls, as accents in the bathroom. (Illustration) On the market today, there are glass mosaic tiles with many colors, which can be used as accent walls for bathroom decoration very aesthetically. In addition, in the dry area of ​​the bathroom, homeowners can use oil-painted walls, lumpy paint to decorate. Phuong Anh (synthetic)

KTS AD + studio said that when receiving the project, the architect realized many disadvantages in the construction context. First, the project is located on the ramp that connects two major roads in the area and has no setback space.

Second, the three sides around the house are obscured by neighboring houses with an average height of three stories. The third is to ask the landlord to wish to arrange multiple private rooms for a family of five in limited space of 36 m².

The architect has overcome the limitation of the location of the project to ensure there is a separate function room for a family of five.

With a high usage density of 10 main spaces including five bedrooms and a number of extra spaces just arranged around the traffic axis.

First, KTS AD + studio offers a solution to divide the building into two parts by height, pushing back the upper architectural block backwards.

This setback will change the elevation of the front façade, the rear part not visible from the street, keeping the house in the neighborhood proportionally.

The recoil of the above volume also increases the natural contact area for the stratosphere, optimally exploiting the light from the east façade.

The architect pushed back the upper architectural block to the back of the house.

With a fairly narrow area, the architect designed a medium-sized kitchen that is arranged on the ground floor, enough for family use.

Functional space is pushed back.

The space in front of the house is planted with many trees.

Next, two floors are arranged in the middle and the end of the building. The rear floor is almost just the ventilation road, which helps to correct the angular ground. The main floor in the middle is only allowed to occupy a small area out of a total of 36 m² of floor area.

The SHIFT concept of functional space towards the East of the architect will create an oblique space, maximizing sunlight for the kitchen and dining area in the morning. This is the most active time of the day.

This procedure is also used for the rear floor clearance, increasing ventilation efficiency, taking in light, and at the same time unifying an overall architectural shape reaching forward.

Two floors are arranged in the middle and the bottom of the house.

A solution to compose the vertical space will not guarantee the intensity of the light, so the architect implements the concept of translating.

That is translating

The functional space faces east to create an oblique void, maximizing sunlight for the kitchen and dining area in the morning.

The stairs change flexibly according to the height and corresponding position between the floors, depending on the oblique direction of the floor pine core.

The ladder body and tread surface use a material that has partial light penetration, allowing light to creep in, creating a shadow effect on the surrounding surfaces.

The ladder body and tread have plenty of gaps to allow light to penetrate to create a shadow effect.

The bedroom has a large, well-ventilated door

KTS AD + studio shared: “The construction site is located next to Cholon, an area full of Chinese culture in Saigon.

With the effort to create a new architecture but not too unfamiliar with the surroundings, the combination of details, selection of materials, colors and decorative lines of the building are inspired by us. from this perspective. ”
