I. EXECUTIVE SUMMARYMission Statement: GreenHouse™ will provide commercial buildings with advanced energy-efficient, cost-effective and convenient lighting. We will provide adaptable lighting systems utilizing the latest in LED technology, minimizing environmental impact and optimize convenience and efficiency.
Problem: Currently, approximately $40 billion dollars a year in energy and expense is wasted in commercial buildings due to inefficient lighting methods such as incandescent bulbs and CFLs (Compact Fluorescent Lighting). In addition, typical lighting methods used in commercial buildings are incompatible with dimmers and timers and release excessive heat. Although Congress passed a law in 2007 essentially phasing out incandescent bulbs between 2012 and 2014, with further restrictions coming into effect in 2020, 48% of commercial buildings still currently use incandescent bulbs as their main form of lighting.
Solution: The GreenHouse™ solution cuts energy costs by up to 50% through a retrofitted system which couples LED lighting with four distinctive strategies (natural light sensors, time scheduling, monitoring of light levels, and occupancy sensors). The GreenHouse™ solution enables buildings to minimize environmental and financial impact by optimizing the amount of lighting produced, while simultaneously improving workplace ergonomics and increasing convenience for building inhabitants.
Industry: Annual LED sales are currently approximately $11 billion and are expected to grow 19% annually. Annual revenues of the lighting systems control components market are estimated to be $2.6 billion, a figure predicted to double by 2016, and triple by 2020.
Target Market: GreenHouse™ will sell its lighting systems for use in commercial buildings in concentrated urban settings across the country. The primary and secondary markets are office buildings and hospitals. Facilities in these markets are heavy users of lighting and incur correspondingly high financial and environmental costs.
Marketing: GreenHouse™ will position itself as the most convenient way to achieve energy and cost efficiency in their lighting. To ensure market presence is achieved, GreenHouse™ will employ an aggressive marketing plan funded by 15% of revenues, including direct marketing, advertising, media and trade shows, and print advertising. The focus of the GreenHouse™ marketing plan will be to inform customers of the benefits available from installing a GreenHouse™ system on a personal basis, conveying that the GreenHouse™ system is a customizable system that can be best suited to tailor to a particular building’s needs.
Management Team: GreenHouse™ has an experienced, passionate, and well-connected group of executives and advisors. Founder and CEO Eva Spitzen will lead the effort to bring GreenHouse™ to success, along with CFO Nobanari Oda as well as a VP of Marketing, VP of Sales, and VP of Technology.
The Board of Directors includes:
Howard E. Janzen, Janzen Ventures Robert Zollars, Vocera Communications Greg Gallo, DLA Piper Jeffery Hillebrand, Northshore University HealthSystem Glenn Schwaber, Israel Cleantech Ventures Merrill Newman, Convergent Technologies
Financial Data: GreenHouse™ requires $2 million to achieve a successful startup. Of this amount, $500,000 has been secured through a combination of personal investment and angel investors, and a further $1,500,000 investment is now required.
Exit Strategies: An exit strategy for early investors in GreenHouse™ is projected to be available after five years of operation, through a sale of a controlling interest, a merger, or an initial public offering. Potential return on investment in these scenarios is 10 to 30 times the original investment.
II. DESCRIPTION AND ANALYSIS OF THE BUSINESS SITUATION
A. RATIONALE AND MARKETING RESEARCHProblem
In the U.S., about 20% of all energy consumed in commercial buildings is wasted.1 Although energy is
always lost when fuels are burned, inefficient technology and design are the main culprits. According to the
Continental Automated Buildings Association, buildings can reduce energy consumption by up to 70% with
updated energy systems.2 Many of these problems are due to the fact that 80% of commercial buildings use either
CFLs or Incandescent bulbs, the drawbacks of which are outlined in the table below.

1. Natural Light Sensors
Sensors will discern the amount of natural sunlight entering a room at any given time, and adjust the amount of artificial light provided accordingly to provide the
adequate amount of light for a given room.
2.Time schedulingTime scheduling will be employed in rooms where sensor controls are not
appropriate. For example, open office space, hallways, and storage room lighting will be controlled automatically.
3. Maximum lighting levels
Maximum levels of artificial lighting depending on the type of activities conducted in different rooms can be controlled to ensure that excess lighting is not wasted.
4. Occupancy Sensors
Occupancy sensors will be installed to detect activity in rooms. This will prevent energy waste by people that forget to turn off lights, and also provide a more
convenient method of turning lights on and off.
II. Proposed Marketing/Promotion Plan
A. PROPOSED PRODUCT/SERVICE Product Details/Plans for Installation
GreenHouse™ systems will be installed by licensed contractors throughout the country, whom
GreenHouse™ will contract as providers of outside services.
Potential Supplier/Manufacturing Plans and Inventory PoliciesAll GreenHouse™ hardware will be manufactured by Chicony Electronics Co., Ltd., a Taiwan-based
multinational electronics manufacturer, in production facilities located in mainland China. Chicony will supply LED
light bulbs for $6 apiece, natural light sensors for $0.30 apiece, and occupancy sensors for $0.35 apiece. Included
in these prices are the costs of wiring and shipping to the GreenHouse™ Silicon Valley warehouse.10 GreenHouse™
will rent a 8,736 square foot warehouse for $5,600 monthly. The warehouse will be located near company
headquarters, in Silicon Valley. In it, GreenHouse™ will keep in stock 90 days of inventory at any given time.
B. PROPOSED PRICING POLICYPricing
One lighting unit will consist of one LED light bulb, one sensor, and one light switch. Therefore,
considering the average size of office buildings in the US is approximately 15,000 square feet, approximately 500
units will be needed, in addition to about 20 hours of a contractor's installation, at about $45 an hour. Therefore
the installation of one GreenHouse™ system in an office building will be priced at about $12,000. Equivalently, the
10 Prices Obtained through a call to Chicony.
average size of hospitals in the US is 120,000 square feet, hence the average price of installation of a GreenHouse™
system in a hospital will be about $60,000.
C. PERSONAL PROMOTIONPersonal promotion will consist of three components: social media, telemarketing, and onsite
presentations, outlined in the table below:
Direct marketing (onsite presentations) Direct marketing will consist of onsite presentations and customer relations. These meetings will be geared towards setting up a plan to satisfy and individualize a particular commercial building’s needs, and establishing plans for future lighting renovations.
Social media GreenHouse™ will create social media pages on websites such as Facebook. These pages will be designed and maintained with the purpose of giving customers an easy means of acquiring information on GreenHouse™ and hearing the latest product news.
Telemarketing In addition to onsite presentations, sales people will acquire lists of local commercial buildings and conduct phone calls in order to spread the word about GreenHouse™ and garner local interest from commercial buildings.
D. NONPERSONAL PROMOTIONGreenHouse™ will employ media promotion as follows:
Advertising Advertising will entail ads in specialty trade journals such as business and healthcare periodicals. Examples include American Medical News, the American Journal of Nursing, and the Wall Street Journal.
Media and trade shows Media and trade shows will consist of paid media attention, media convention spots, and trade show booths in expos. GreenHouse™ will have booths at both green expos and commercial construction conventions, such as the GreenTech Expo and the Commercial Construction Show. This will allow the demonstration of GreenHouse™ products to potential customers.
MARKETING BUDGETGreenHouse™ will allot 15% of total
revenues to marketing. Following extensive
market research, it was determined that this
budget will be most effectively allocated as
follows: 50% direct marketing, 30% print
advertising, and 20% media and trade shows.
Marketing in both target markets, office
buildings and healthcare buildings, will be
effectively reached through this allocation. 50% of the total marketing budget will be allocated to office buildings
and 50% to healthcare buildings.
E. PLACE
Depicted above is the basic business model for GreenHouse™, which will be utilized to generate revenue
as the business grows. It includes expenses on the left, value proposition in the middle, and revenue on the right.
This business model is easily scalable and will allow GreenHouse™ to reduce production costs as it begins to
expand operations.
The GreenHouse™ Distribution model consists of GreenHouse™ purchasing lighting system components
from its manufacturer, Chicony Electronics™, and directly installing them into customers’ buildings through
partnerships with outside contractors.

Proposed plan to meet capital needsEva Spitzen has invested $400,000 collectively out of the $2 million required for startup.
Having acquired $400,000 of the $2 million needed for startup, GreenHouse™ necessitates $1,500,000
from venture capital firms and an additional $100,000 from Angel Investors.
In return, GreenHouse™ will offer investors equity of proportional value to the amount invested.
GreenHouse™ does not require short-term or long-term borrowing.
C. CAPITAL AND REPAYMENT PLANSCapital startup investments will be repaid in proportion to the holding of GreenHouse™ equity at the end
of its investment period. There are three profitable ways GreenHouse™ can exit the market:
Sale of controlling interest (51%) Sale of 100% of company (e.g. merger)
Initial Public Offering

Listed below are the competitive advantages and disadvantages of GreenHouse™.
Table 2 Competitive AnalysisAdvantages Disadvantages
Growing Industry- As more commercial businesses attempt to balance energy efficiency and cost effectiveness, a booming growth in the LED industry has occurred, growing 388% in just six years and reaching $12.8 billion in 2010. It is expected that this industry will continue to grow throughout the following years, presenting the perfect opportunity for GreenHouse™ to provide companies with a convenient way to save money and energy.
Problem: Lack of position- As a new start-up company, GreenHouse™ has yet to develop brand awareness as the addressable market is currently unaware of our abilities. We plan to sell an innovative method of energy conservation which our target market does not fully appreciate.Solution- Aggressive marketing strategies will ensure our company becomes known to the target market for its money and energy-conserving strategies.
Government incentives- Using GreenHouse™ systems provides companies the opportunity to apply for certification from government agencies such as Leadership in Energy and Environmental Design, or LEED, which include payback in some areas in the form of tax benefits.
Problem: Start up costs- GreenHouse™ anticipates $1 million in start-up capital, but further analysis is needed to anticipate other possible obstacles.Solution- GreenHouse™ will secure liberal start-up funds to account for unanticipated hurdles. An experienced Board of Advisors and Executive Team will ensure uncertainties can be addressed in an efficient manner.
High profit margins- As one of the first emerging companies in the industry, GreenHouse™ will be able to set the price for system installation, leading to high profit margins.Innovative application of technology- Although LEDs are gaining popularity in recent years as alternative home lighting systems, LED lighting is not yet common in commercial buildings. Thus, GreenHouse™ will have a first mover advantage.
