ENERGY CODES AND STANDARDS FOR THE BUILT ENVIRONMENT Richard Lawrence, PMP Interim Director, Engineering Division

Energy Facts about Buildings Buildings account for one-third of the world’s total energy use and associated Greenhouse Gas Emissions (GHG) More than half of electricity produced is consumed by buildings Typically 10%-20% of total life-cycle energy consumed is used for the manufacture and assembly of building materials, construction and maintenance 80-90% is used for heating, cooling, ventilation, lighting & appliances

History of the Building Code 1/3 1908 - KSAC Building Regulations drafted. - response to public and private pressures against poor engineering standards after 1907 earthquake. - based on 1892 London Building Regs. - restrictive, inflexible & required frequent modifications - this was a KSAC only effort.

History of the Building Code 2/3 1962 - revision of KSAC Building Regs. 1965 final draft regulations were presented to Cabinet and KSAC for ratification. Regulations redraft remained in limbo for 9 years! 1974 a major redraft of the 1965 effort updating technology and revising administrative contents.

History of the Building Code 3/3 1981 Committee appointed to revise 1974 KSAC draft Regulations into an Islandwide Code. 1991/ 92 - the National Building Code was Metricated 2008- I-Codes adopted as new National Building Codes

Key Focus of the IECC The International Energy Efficiency Building Code (IECC) Application Document addresses energy efficiency or conservation for: all types of commercial, office, hotel, high rise residential and, detached multi-family residential buildings. EXCEPTION - industrial plants and special purpose buildings

Key Focus of the IECC The Jamaican Application Document for the IECC is based on: IECC ASHRAE’s 2004 Advanced Energy Design Guide for Small Commercial and Residential Buildings Jamaican Energy Efficiency Building Code.

Key Focus of the IECC The Jamaican Application Document applies to both conditioned and unconditioned buildings (buildings with neither heating nor air-conditioning). IECC only applies to conditioned buildings

Key Focus of the IECC Structured into TWO Parts: Part 1 which deals with energy saving requirements for 3 sizes of unconditioned buildings Part 2 has two sections that deal with conditioned Residential Buildings and Commercial / High Rise Residential Buildings.

Key Focus of the IECC Seeks to prevent the continued use of energy efficient room air-conditioners (split units, cassettes and to a lesser extent window air-conditioners) in inappropriate places such as: high density occupancy areas, rooms requiring air changes to prevent the build-up of pathogens, viruses, germs, bacteria, etc.

Key Focus of the IECC Three climate zones in the island defined by temperature characteristics in terms that designers can utilize to save on energy consumption in that climatic zone: Southern Northern and Midlands Highlands

Key Focus of the IECC The unconditioned building size stratification corresponds roughly with: low, middle and upper income strata energy requirements Energy saving requirements increasing as you go from the smaller to the larger size building category.

Key Focus of the IECC For unconditioned buildings the prescriptive method is used for compliance. Designer is given: the energy goals to be achieved the strategies for achieving the goals the practical steps for achieving the goals.

Key Focus of the IECC Examples of the requirements to be satisfied are: Low Income – energy efficiency lighting, insulated roof, keeping direct radiation out of building, maximizing cross ventilation and openable window space of 10%. Middle Income – all the above plus maximizing the use of daylight, use glass with low solar heat gain, use of solar or gas water heaters and openable window space of 12½%. Upper Income – All the Low and Middle income requirements plus better lighting and power controls as well as openable window space of 15%.

Key Focus of the IECC Part 2 - Residential section of Conditioned Buildings gives designers the following options for arriving at acceptable energy efficient designs: Residential Building Design by Systems Analysis and Design of Buildings Utilizing Renewable Energy Sources Residential Building Design by Component Performance Approach Energy Design by the Advanced Prescriptive Method for Residential and Small Commercial Buildings.

Key Focus of the IECC The Jamaican Application Document gives advice on when to use a particular method The Designer is required to declare the method used for his design so the compliance evaluator can know for what to check. The energy design by Advanced Prescriptive Method will ensure the greatest energy saving (as much as 30% more than the other!)

Key Focus of the IECC The IECC Chapter 7 (Design of Energy Efficient Commercial Buildings) excluded. Replaced by Design by Acceptable Practice for Commercial and Conditioned High-rise Residential Buildings. This section of Part 2 is the Jamaica Energy Efficiency Building Code of 1994. (The section underwent minor changes to reflect the technological changes that has occurred since 1994)

Key Focus of the IECC Section 2 Part 2 - Three proposed methods for designing to meet this section of the code: Prescriptive Requirements System Performance Requirements Whole Building Analysis Methods

Key Focus of the IECC Minor Changes to the Jamaica Energy Efficiency Building Code of 1994 in Section 2 Part 2: The targeted values to be met for the prescriptive and performance requirements to be met. The design approaches to be followed in the Whole Building Analysis Methods of Cost by Energy Consumption and Energy Cost budget The effect on building energy consumption of maximizing the use daylight.

Key Focus of the IECC Minor Changes to the Jamaica Energy Efficiency Building Code of 1994 in Section 2 Part 2: Design requirements for 5 areas of a building that must be targeted to save energy: building envelop, electrical power, lighting, air-conditioning and maintenance

ISO 50001:2011 Energy Management Systems Standard (Requirements with guidance for use)

PDCA Cycle ISO 50001 is based on the Plan-Do-Check-Act management system model The company’s bottom line will be the primary driver for design & implementation

How does it work? Provides strategies to increase energy efficiency, reduce costs & improve energy performance Provides access to a single, harmonized standard for implementation across all Branches/Departments.

How does it work? Fully customized to Individual Customers’ needs: Measure the results Review the effectiveness of the policy Continually improve your energy management
