BACKGROUND YULE MOUNTAIN BOUTIQUE HOTEL
Yule Mountain boutique hotel, an old-fashioned farmhouse run by a peasant couple in

Taihuyuan, Lin'an, Hangzhou, China, had developed an excellent reputation. Baisha village,
where Yule Mountain boutique hotel located, is situated on creek Taihuyuan which surrounded
by Tianmu Mountains. The region around Lake Tianmu, China is also known as the Lin'an
Taihuyuan Scenic Area, which first became a popular tourist attraction in the 1990s. The
traditional Chinese farmhouse style was all the rage in those days and many of the
accommodation facilities of the time reflected that.

This hotel 1,100-square-metre offers a serene atmosphere in a lush green among the
forest. The Yule Mountain Boutique Hotel occupies a unique footprint as it divides a scenic
highway and a mountain range. A former urban infrastructure in an effort to bond guest with
nature. The designer reduced the room count 30 to 15 create more spacious interiors. Carved
timber elements echo historic Chinese traditions.

However, this hotel could barely stay afloat under the price of 200 yuan per person,
which includes board and lodging in recent years. For these reasons, the owners decided to
transform the farmhouse's physical space, hoping to increase profitability and improve the
guests' living experience, rendering the Yule Mountain farmhouse from the farmhouse a
boutique hotel. After accepting the invitation from the owners, Continuation Studio launched
the renovation project with architecture and interior design. The structure that was given a
complete makeover by Hangzhou-based Continuation Studio in 2016 until 2018, founded by
Fan Jiujiang and Zhai Wenting in 2015 with design team members Kai Yu, Kai-Xiong Chen,
He Huang, Ting Li, and Run Jin as intern.

PHASE 1: HOTEL DESCRIPTION
1.1 Geographic and Demographic

Yule Mountain Boutique Hotel is located by the creek Taihuyuan which surrounded by
Tianmu Mountains in Lin’an District, Hangzhou, Zhejiang, China. This boutique hotel was
surrounded by a provincial highway and mountain slopes. It can only be accessed through a
provincial road, just like an idyllic hideaway. Due to the development of the tourism, scenic
spots scattered here and there in the surrounding countryside along with them, various
farmhouse hotels are built to host guests. There was a bamboo forest in the north side and it
was having the creek, which is about 3 meters lower than the rood flows, from north to south
at the east side. When it rains, the sound of the creek can be heard in the building.

Lin'an District is one of ten urban districts of the prefecture level city of Hangzhou, the
capital of Zhejiang Province, East China. Lin'an held a population of 573,100, over an area of
3,124 km2 (1,206 sq mi). It is located in northwest Zhejiang covering the far western suburbs
of Hangzhou, and borders Anhui province to the west and northwest. Hangzhou is classified
as a sub-provincial city and forms the core of the Hangzhou metropolitan area, the fourth-
largest in China. It has water communications with the interior of Zhejiang to the south, is the
southern terminus of the Grand Canal, and is linked to the network of canals and waterways
that cover the Yangtze River (Chang Jiang) delta area to the north. During the 2010 Chinese
census, the metropolitan area held 21.102 million people over an area of 34,585 km2 (13,353
sq mi). Hangzhou Prefecture had a registered population of 10,360,000 in 2019.

Lin'an is rich in natural resources, abundant in rainfall, and has a warm climate. All of
these factors work together allowing the district to be covered with 71.3% forest. Such an
ecological environment breeds more than 4,700 biological species. Mountains, lakes, forest,
hot springs, caves, and other ancient remains are everywhere. The climate in Lin'an is temperate
and humid subtropical monsoon. The annual average temperature is 16.0 °C (60.8 °F) with
1,460 mm (57 in) of precipitation.

1.2 Design and Construction

Design practise Continuation Studio renovated the Yule Mountain Boutique Hotel in
Hangzhou, China, one of the country’s most popular holiday destinations. The old-fashioned
farmhouse property has been operated for over a decade by a local couple who had faced
challenges regarding hotel rates and a discrepancy between peak-season and off-season
numbers. Rather than let the business slip further into a lull, the owners decided to transform
the physical space and breathe life back into the hotel. Continuation Studio, after accepting the
invitation of the proprietors, launched the renovation project with architecture and interior
design. The hotel built throughout the country in the early 2000s.

The property is set on a creek and surrounded by mountains, accessed via a single
provincial road. Continuation Studio recognized the surrounding landscape and terrain as the
unique drawcard of the hotel. The designers created a ‘dramatic entrance’ featuring a raised
terrace, screen wall and timber-framed staircase, seeking to isolate the site from the external
world and assist guests in disconnecting and relaxing. Set in front of the lobby, the shallow
pool in the inner courtyard represents ‘the art of doing nothing’, aligned with Zen philosophy.

However, instead of enjoying the water and mountains nearby, guests still in the hustle
and bustle of the city owing to the noisy provincial road, the unclear boundaries of the site and
the sealed space setting of the guest rooms. The beautiful scenery became a useless background
rather than a valuable landscape. The neglected landscape must be revealed from the noisy
environment and become the theme of the spatial experience. “Reunite with landscape” became
the goal of this project. Landscape, as spiritual and physical sustenance of Chinese people, is
the everlasting spatial subject for space creators to borrow ideas from.

The design of a series of penetrable interfaces including tea pavilions, balconies, and
rill house, working as a transitional space between mountains and the interiors. The buffer
defines the space from the aspect of the physical experience of guests, meanwhile, it re-
establishes a new connection between both sides of the interface with distinct strategies. Also
the dining room of the original building on the 2nd floor is designed to be a separated rill-view
room during the renovation.

The renovation of Yule mountain boutique hotel took more than 2 years from the design
to the formal operation, more than 1 year they expected at the beginning. This allows them to
rural situations under the non-professional construction project accumulated a wealth of
experience. Reviewing process, many times they faced the situation that the plan cannot be
implemented.

Without professional master builder got involved, owners and designers show complete
trust to each other, solving problems including construction mistakes, material replacement and
the change of structure and so on. As designers, they also make full use of the resources for
this project such as design, materials, construction, post-layout and other favourable
conditions. The final completion is about 70%, which is a very lucky result.

1.3 Space/Units Allocation

The design and space allocation of Yule Mountain Boutique Hotel is very unique. In
Yule Boutique hotel has 4 storey and 3 rooms on each floor and a balcony extend from each
room, of which has the external space to enjoy the nature. The number of rooms is 15 units and
the reconfiguration of the plan makes each bathroom has landscape viewing.

The main entrance of the four-story main building is at the north facade to the east
gable, a triangular area circled by the wooden corridor, the two-story annex and main building.
From the staircase to the gable, the circulation has a non-orthogonal turning point, as a result,
firstly the deflection between the scarp and the gable is integrated with the sequential boundary
of the circulation. Secondly, the external space on the terrace is have the triangle courtyard and
inner courtyard with water, which possess distinct ambience and scale respectively.

The shallow pool in front of the lobby forms the main part of the inner courtyard. It
explains the ‘Emptiness’, meaning Close to nothing in Zenism, and also reflects the mountain
and sky in distance. Standing in the centre of the lobby and looking at the courtyard, visitors
would face an open and clear sight, totally distinct from the shadowy corridor space a placid
water spreads out under the eaves of the lobby, in which the cloudy top of mountains behind
three walls and bamboo forests, the long pavilion on the left side, and the homogeneous timber
grill of the waterside pavilion (horizontal wooden frame when seen from the provincial road)
are reflected, and a sublime landscape picture is created in visitors view.

The inner courtyard and the external entertainment area are separated by a corridor with
a masonry wall. The themes of contemplation of the landscape and hiking through the
mountains are elaborated via a series of contrasts between the two areas which are the plane
and the ramp, the stillness and the movement, the foreground and the background.

The external entertainment area on the side of the mountain was originally a steep slope.
An experiencing space for various events and activities was arranged in the mountains part,
and it is natural to put various active areas on different levels of the slope. They combined the
structural requirements of the retaining wall to solve the height problem by stacking small stone
pieces to platforms, on which barbecue bonfire area and hot spring pool area are set up for
socializing. Functional areas are connected by circulation, and is arranged according to the
privacy requirements.

The tea pavilion is the place to people relaxing and refreshing their mind also their
body. Outer side of tea pavilion, not only is the main surface facing the road, but a viewing
surface to enjoy the creek-side landscape.

1.4 Building Material/Fabric Identification

Building material is any material that can be used for construction purposes. It
commonly includes wood, concrete, steel, cement, aggregates, bricks, clay, metal, and so much
more. In the olden times, people have been using pure bricks or wood, or straw. But in this
modern age, engineers have learned to mix and match the right materials to come up with
higher quality structures. Yule Mountain Boutique Hotel surrounded by a provincial highway
and mountain slopes. This hotel was symbolized by the use of imitation blue brick veneers,
flush gable roofs and exquisitely carved timber doors and windows, forming the 'traditional
Chinese' farmhouse style.

Overall, the hotel uses ancient wood veneer materials and is combined with other
materials such as glass, steel and also using stone wall. Mostly, this hotel using wooden as the
main materials to install structure porch, the collage of windows and doors, walls and wooden
grill.

Besides that, the interface of balcony was made by two-layer insulation and soundproof
glasses and the flat roof deck was made by steel on the guest room. This hotel also using
bamboo forest in the north side of the courtyard to separating the courtyard from the neighbors
a red-brick building. To forming a terrace their using a 3-meter depth traditional double-slope
wooden pavilion as the boundary of the terrace.

Inner side interface of tea pavilion is comprised of fine timber grill modules, which hide
the column of pavilion from inside view. Pure timber modules and smooth asphalt roof possess
a similar two-dimensional interface with fine texture, setting off the beauty of the permeated
landscape.

Also, the hotel build an overhanging steel structure area from the original concrete
structure, adding a balcony to each room which can interact with the exterior landscape and
using timber grilles in the external of the balconies. Furthermore, using timber grilles in the
external of the balconies of guest rooms on the 3rd and 4th floor, which not only keep out the
sightlines from external world to the bathroom. At the bottom of pool in the inner courtyard
was using the old objects such as tiles.

This hotel was designed a series of continuous fully opened windows which is
composed of angle steels and timber grill. One-meter high wall under the windows constitute
a part of the base embellished by bamboos.

PHASE 2: SYSTEM IDENTIFICATION, INSTALLATION FROM THE RETROFIT
WORKS

2.1 Light Retrofitting
A lighting retrofit is simply an upgrade to the light fixtures or lamps, increasing energy

efficiency. Energy savings often offset the cost of these projects over time, while improving
light levels and eliminating maintenance headaches.

The Yule Mountain Boutique Hotel using 50% of LED lighting for the energy saving.
This idea for implementing green building practices. This hotel can reduce around 35% of
energy consumption when using LED lighting. This hotel uses slim line bar LEDs under the
wall and under the beds to increase the level of lighting in the area. However, the hotel has its
disadvantages. This hotel still using CFL (compact fluorescent) bulbs for their main lighting
such as down light at stairway space (dining room behind the window), courtyard pillars and
some at the bedroom.

Figure 16: Down light at stairways and courtyard pillar
17

The number of rooms reduced from 30 to 15 and the reconfiguration of the plan makes
each bathroom has landscape viewing. During the day the hotel uses natural light. The numbers
of windows are over 80% in this hotel. The large glasses doors have been installed at bedroom,
dining room and other place. The oversized windows and doors can reduce energy consumption
during the day because the large space causes sunlight to fill the entire space. They typically
use less energy and materials and improved indoor air quality, which improves the health of
occupants.

2.2 Lighting Retrofit Strategies
Lighting retrofits are one of the most cost effective means of improving occupant

experience and increasing asset value while reducing operating costs. Recent and dramatic
improvements in LED technology, coupled with innovative control systems, make meeting or
even exceeding our recently tightened energy codes a short payback exercise in the vast
majority of buildings.

2.2.1 Lamp, Ballast and Luminaire Replacement
Firstly are lamp, ballast and luminaire replacement. A new generation of lighting

retrofit kits is available in energy efficient LED option. According to Vogel (2012), these kits
enable component parts to be installed in 15 minutes or less into the housing of old fixtures,
provide better quality and better looking fixtures and involve minimal disruption because they
are installed below the ceiling. LED replacement kits with dimming control. LED retrofit kits
provide the required electrical components, diffusers for glare control, and LED arrays in a
pre-packaged kit, allowing existing linear fluorescent luminaire housings to remain in place.
Installation requires removing the existing fluorescent lamps and ballasts, leaving only the
luminaire housing. This approach is particularly effective in installations where it may be
difficult to remove the existing luminaire housing. This approach can provide a higher level of
safety and performance than TLEDs at a similar or somewhat higher cost. Replacement of
lamp, ballast and luminaire appears as the most often reported lighting retrofit strategy, with a
great saving potential. The most common existing lighting installations consist of fluorescent
lighting (with conventional ballasts) and most commonly retrofitted fixtures are the four-lamp
T12 and parabolic and lenses troffers with T12 or older T8 lamps (data from the USA).
Compared to fluorescent lighting, LED lamps have reduced energy consumption
(approximately 50%) and a longer life time.

19

2.2.2 Control Systems

The use of control systems is in order to provide light exactly at the right time, to the
right level and in the right place. It can significantly contribute to reduce the consumption of
electricity for lighting. With partial daylight that linked dimming control, they obtained a
potential energy saving between 9 and 37% of the total energy consumed and 18 to 37% with
total lighting control. The use of electric lighting control systems can also significantly reduce
the consumption of electric lighting but the saving potential varies greatly according to context
and building, which leads to difficulties in estimating the payback time of a lighting retrofit.
Simulations generally overestimate the savings compared to field studies; especially when the
control system involves advanced automation and/or technology, such as daylight harvesting
technologies. Manual control systems, such as door switches, manual task lamps and manual
dimmers, can offer an unexpectedly high saving potential with increase in occupant satisfaction
and productivity. Occupancy based lighting control systems are also very promising with high
expected savings (20-93%). Irregularly occupied spaces offer higher saving potential.
Optimizing the time delay has a significant impact on the energy savings. Using a presence
(on/off) control system could yield higher energy use for lighting than a simple manual switch
at the door combined with absence detection (switch off), especially in individual or small
offices. Daylight-linked control systems can result in significant lighting savings, but several
studies report difficulties in real installations and in estimating the payback period at the design
stage.

2.2.3 Daylighting

Daylight (and electric lighting) performance is greatly affected by the reflectance of
interior surfaces, such as walls, ceilings, flooring, and furniture. Dark interior surfaces absorb
light while lighter surfaces reflect light, increasing levels of illumination throughout the space.
This increased reflectance reduces the contrast between daylight apertures and interior
surfaces, greatly improving visual comfort. If dark surfaces limit the effectiveness of
daylighting, consider changing their reflectance by painting them with higher reflectance paint,
preferably white, which reflects the whole daylight spectrum and maintains daylight’s excellent
color rendering properties. If you decide to increase the reflectance of interior surfaces, you
should also consider a texture that diffuses the reflected light, to better spread the daylight (and
electric lighting) throughout the space and minimize glare. It is also helpful to make sure
partitions do not block windows. Orient low partitions parallel to walls with windows and

20

orient high partitions vertically, to help distribute daylight deeper into the space. Yule
Mountain Boutique Hotel use a pool to reflect daylighting into the part of building such as at
lobby, tea pavilion and also the corridor. The tea pavilion on the waterfront, the veranda, the
sky and mountains are reflected in the water, becoming the protagonist of the picture. The
shallow pool can reflect the mountain and sky in distance so that means the hotel use lighting
daylight to ensure people will get a perfect view.

two-dimensional interface with fine texture, setting off the beauty of the permeated
landscape.

2.3 Thermal Insulation

Thermal insulation usually refers to the use of appropriate insulation materials and
design adaptations for buildings to slow the transfer of heat through the enclosure to reduce
heat loss and gain. The transfer of heat is caused by the temperature difference between indoors
and outdoors. Heat is lost or gained by transmission through the ceilings, walls, floors,
windows, and doors. Thermal insulation in buildings is an important factor in achieving thermal
comfort for its occupants. Insulation reduces unwanted heat loss or gain and can decrease the
energy demands of heating and cooling systems.

Structural Insulated Panels (SIPS) are an advanced method of construction offering
excellent thermal performance, light-weight structural strength and time and cost saving
benefits over traditional construction methods or systems. SIP panels are used in floors, walls
and roofs for residential, commercial and educational applications, providing ecologically
friendly and energy efficient buildings.

Figure 21 : Example of Structural Insulated Figure 22: SIPS Diagram
Panels (SIPS)

SIPS is superior thermal performance. It will last the life span of the building. This is
because of the solid core of polyurethane (PUR) insulation throughout the structure which
ensures that the building is heated evenly, remains free from cold spots and will benefit from
reduced heating costs. This system will provide a comfort environment to hotel guests.

SIPS offer extremely high thermal performance, the Polyurethane (PUR) core of rigid
insulation and OSB/3 achieves U-Values as low as 0.10 Watts per Meter Squared Kelvin
(W/m²K) or better, making significant savings on annual heating costs.

23

SIPS also is environmentally friendly. SIPS are made from timber which is sourced
from managed plantations. Timber is a green building material because trees produce oxygen
and remove carbon dioxide from our atmosphere and timber is the only truly renewable
building material. The polyurethane (PUR) core of insulation in the SIPS is CFC/HCFC-free
with zero Ozone Depletion Potential and has a Low Global Warming Potential (GWP). This
will prevent any harm to nature environment.

Figure 23: Blue brick veneers wall
Yule Mountain Boutique Hotel also use blue brick veneers to build a wall. Blue brick
veneers are lightweight material, and it easy to install. It also a great insulation material. Blue
brick veneers increase the total R-Value of the exterior walls of hotel. Foil-faced
polyisocyanurate insulating sheets is installed directly to the sub-siding. This type of insulating
board comes in thicknesses from one-half to 2 inches thick. Each inch of thickness provides an
additional R-6.5 of insulating power. Even a less expensive, thinner foil-faced closed-cell foam
sheet beneath the brick veneer will significantly add to the hotel’s thermal resistance.

24

2.4 Water Heating
The type of solar water heating to be installed is evacuated tube collector. This type of

solar water heating also needs the electrical power when it is needed while in winter season or
when there does not have sunlight to heat the water in the tube. It will reduce the electrical fees

For the original design and feature in the hotel, water heater system was not applied.
For the renovation, we have planning to install the water heater in every bath room in the hotel.
China is also the four-season country and the installation of the water heater is very important
to face the low temperature. It also can increase the numbers of guest due to the comfortable
hotel and have a great service.

We are agreed to choose the solar water heating to be install in the hotel because it has
a lot benefit to the owner and also to the surrounding. Water heating is the highest single-end
energy usage in the hotel industry, accounting for about a third of the overall energy use. Hot
water may be free to guests, but hotel managers realise that their ever-increasing service bill
counts towards every bath, shower, kitchen and laundry. Installing solar water heating is going
to save us a lot of money over the long run, well beyond the payback – and we can feel better
about reduced environmental impacts.

The Yule Mountain Boutique Hotel water heating system will save nearly 3,900 therms
(390 million BTUs) of natural gas yearly, resulting in more than 22 tons of greenhouse gases
offset by the system each year. Over the lifetime of the system, this is the equivalent to carbon
sequestered by 424 acres of forest over one year or Greenhouse Gas (GHG) emissions
reductions equivalent to removing 109 cars from the road.

25

2.5 Air Conditioning Retrofitting
Yule Mountain Boutique Hotel using Ductless Mini split air conditioner in the original

building. Ductless Mini Split air conditioners consist of external units and internal units. The
outdoor unit is mounted on or near the outside wall of the room. This unit houses the
compressor, condenser coil and expansion coil or capillary tube. The interior unit contains a
cooling coil, a long blower and an air filter. Installation of split air conditioners is easier because
it does not require duct work. Instead, the internal and external units are connected by a set of
electrical wires and tubes. Duct work required for many traditional AC units generally
increases energy production, as many centralized AC units lose a lot of energy due to heat
exchange in the air duct system. Without a duct network, there is very little chance of heat or
energy loss in a split air conditioning system.

This kind of air conditioner system has many advantages over traditional AC. One
obvious benefit is the quiet performance of a split air conditioner system. The parts of an air
conditioner that make the most noise are the compressor and the fan that cools the condenser.
In a split system unlike a window unit, the compressor and fan for the condenser are located
outside the room being cooled and therefore the major sources of noise are removed.

Another perk of going the split system route is how easy the unit is to operate and keep
maintained. Most systems come with basic remote control that easy to use. They can also
include, as an optional extra, a wall mounted thermostat which makes temperature control easy
and convenient to manage. The design of both the indoor and outdoor components also lend
themselves to uncomplicated servicing.

Duct work required for many traditional AC systems generally increases energy
expenditure. Heat exchange in the air duct system causes energy loss. Since mini splits have
no ducts, they avoid the energy losses associated with ductwork of central forced air systems.
Duct losses can account for more than 30% of energy consumption for space conditioning,
especially if the ducts are in an unconditioned space such as an attic.

26

2.6 Water Consumption Retrofitting
Yule mountain boutique hotel was use the water from the mountains. It also uses

indirect water supply system because the main water comes in via a rising main and directly
feeds at least one cold tap at the kitchen sink with potable water (water which is fit for drinking
and cooking) and may also feed a washing machine, a shower and an outside tap. The rising
main also feeds a storage tank at a high point in the building from where the water is fed to all
the other taps using gravity.

In Yule mountain boutique hotel was install the low-flow water system for their water
consumption. The low-flow features can reduce water usage by as much as 30%. The designed
on the same gravity-flow principle as standard toilets but holding less water.

2.7 Smart Safety, Security and Auxiliary System Retrofitting
Yule mountain boutique hotel have covers the internal and external security of the

guests and the staff of the hotel. The internal security covers security issues against theft, fire
safety and even tracking the unwanted guests in the hotels. The external security aspect covers
the incidents inside and outside the premises of the hotel. The external security measures used
are proper manning of security guards in the hotel, proper fencing of the pool area and even
the installation of 24 CCTV (Closed circuit television) cameras within the campus of the hotel.

Yule mountain boutique hotel use the alarm system for fire safety. The alarm system
provide notice to at least the building occupants usually transmit a signal to a staffed monitoring
station either on or off site. Key Card Locks also use in this hotel for security. The key card
locking system (Electronic Locking System) directly interfaced with the Property Management
System of the hotel so that guest room access can be supervised.
